Background

A child seat system has been proposed having at least one base module which can be fixedly mounted in a motor vehicle and an infant seat which can be fixedly connected in the base module for transporting a child in the motor vehicle.

Disclosure of Invention

The invention is based on the object, inter alia, of providing a device of this type with improved properties with regard to safety and comfort. According to the invention, this object is achieved by the features of claim 1, while advantageous embodiments and refinements of the invention are obtainable from the dependent claims.

The invention relates to a child seat system having at least one base module which can be fixedly mounted in a motor vehicle and an infant seat which can be fixedly connected in the base module for transporting a child in the motor vehicle.

The invention proposes that the infant seat has a weight of less than 4 kg. In this context, an "infant seat" is to be understood to mean, in particular, a transport seat for a child, in which a child up to 15 months of age and/or a weight of up to 13kg from birth can be transported in a safe and suitable manner for the child, in particular in a motor vehicle, wherein the child transported in the infant seat is transported in the infant seat essentially in a lying-down manner. In this case, the infant seat is in particular designed such that infants of different ages and lengths can be transported in different lying positions in the infant seat. In principle, it is also conceivable for the infant seat to also be provided for transporting a child outside the motor vehicle; it is thus conceivable, for example, for the baby seat to be connected to a stroller frame via a coupling module, in order thus to form a stroller together with it. The child seat system, in particular the infant seat, is configured to comply with, in particular, ECE standard R129. A "base module" is to be understood here to mean, in particular, a module which is intended to be fixedly mounted in a motor vehicle, in particular on a motor vehicle seat, and which has at least one connection region for an infant seat, via which the infant seat can be connected to the base module in a fixed and secure manner. The base module is provided for ensuring that the infant seat is reliably secured in the motor vehicle. The base module is configured as a seat base. Preferably, the base module comprises: a rigid substrate; a bearing block arranged at the front end of the base body and provided for supporting in the extended state at the foot region of the motor vehicle; and/or at least two form-fitting elements configured as ISOFIX, which are arranged at the support structure of the motor vehicle seat. In this context, "fixedly mountable in a motor vehicle" is to be understood to mean, in particular, that it can be rigidly connected to a support structure of the motor vehicle for safe transport. The base module is connected to a support structure of a motor vehicle, in particular of a motor vehicle seat or of a motor vehicle bench seat, in particular by means of at least one form-fitting element. The base module is especially arranged to remain in the motor vehicle when the infant seat is used for transporting a child outside the motor vehicle. By "weight below 4 kg" is to be understood in particular that the weight of the infant seat is below 3.9kg, preferably below 3.5kg, in a particularly advantageous embodiment below 2.8 kg. "provided" is to be understood as specially designed and/or equipped. An "object provided for a specific function" is to be understood to mean that the object fulfills and/or executes the specific function in at least one application and/or operating state. It is therefore particularly advantageous if the infant seat is of light construction and is improved, in particular for use outside a motor vehicle.

Furthermore, it is proposed that at least one function and/or safety element required for transport in the motor vehicle is arranged on the base module. A "functional and/or safety element" is to be understood here to mean, in particular, an element which is provided to ensure child safety during transport of the motor vehicle and/or is provided to perform at least one function at least during transport in the motor vehicle. A "functional element" is to be understood in particular as a comfort or holding device for a child seat system, wherein the holding device is provided in particular for accessories that are customary for children. The functional element configured as a holding device is preferably a pacifier mount, a water bottle mount, a tablet computer mount or another mount that is of interest to the person skilled in the art. In principle, it is also conceivable to design the functional element as a camera and/or a camera support, a mirror, a sunshade, a sound system or another element that is relevant to the person skilled in the art, with which the parent can ensure the comfort of the child or monitor the child, in particular during driving. In this case, "arranged at the base module" is to be understood in particular to mean that the base module is connected fixedly at least in the installed state. In this case, the functional and/or safety elements arranged on the base module are also arranged on the base module, in particular in a state in which the infant seat is separated from the base module. The infant seat is thus advantageously constructed to be light.

It is also proposed that the base module is provided for absorbing at least a large part of the impact energy in the event of a frontal impact. In this context, "crash energy" is to be understood to mean, in particular, an energy, in particular an impact energy, which acts on the motor vehicle and/or the child seat system in the event of a crash or in a crash test. In this context, crash energy is to be understood to mean, in particular, deceleration energy and/or impact energy generated by elements of the motor vehicle which are in contact with the child seat system. A "frontal collision" is to be understood here to mean, in particular, a collision in which a deceleration takes place in the direction of travel, i.e. in the seat direction of an infant seat arranged correctly in the motor vehicle. "largely" is to be understood here to mean, in particular, at least more than 50%, preferably more than 75% and particularly advantageously more than 99%. In this context, "absorbing the crash energy" is understood to mean converting and/or guiding the crash energy into a support structure of the motor vehicle, bypassing the infant seat. Advantageously, the base module is provided for absorbing the impact energy at least substantially also in the event of a side or rear impact and here absorbs at least a major portion of the impact energy occurring. The child seat system is thereby configured to be particularly safe and the infant seat is advantageously configured to be light.

It is furthermore proposed that the base module is provided for at least substantially covering the infant seat in the mounted state at least in the shoulder region and/or the hip region. In this context, the term "installed state" is to be understood to mean, in particular, a state in which the infant seat is correctly connected to the base module in a fixed and loss-proof manner. In this context, "shoulder region" is to be understood to mean, in particular, the region of the infant seat in which the shoulders of a child lying in the infant seat are located. In this context, "hip region" is to be understood to mean, in particular, the region of the infant seat in which the hips of a child lying in the infant seat are located. In this context, "at least substantially covers" is to be understood in particular to mean that the base module covers the infant seat up to at least 50%, preferably at least 75% and in a particularly advantageous embodiment at least 95%, in particular in the shoulder region and/or in the hip region in the side view. The child seat system can thereby be constructed in a particularly safe manner, wherein in particular the infant seat is advantageously constructed to be light.

It is also proposed that the infant seat have a carrying handle which is provided for absorbing impact energy in the event of a side impact together with the base module. In this context, a "carrying handle" is to be understood to mean, in particular, an element, in particular a carrying element, which is provided such that the infant seat can be carried thereon. The handle has a substantially U-shaped curve. The handle is arranged with a first end at a first left side of the infant seat and with a second end at a second, opposite, right side. The handle is designed as a rigid element. The carrying handle is connected to a base body of the infant seat, which is configured as a support structure for the infant seat. Here, the carrying handle is movably connected with the infant seat. The handle is adjustable relative to the infant seat. In this context, a "side impact" is to be understood to mean, in particular, an impact transverse to the seat direction of the infant seat, in particular transverse to the direction of travel of the vehicle in which the child seat system is arranged. Thereby, the infant seat can be constructed in a particularly safe manner.

It is also proposed that the child seat system has at least one energy absorption unit which is arranged at least partially between the base module and the infant seat. An "energy absorption unit" is to be understood here to mean, in particular, a unit which is provided for converting movement energy, in particular into deformation energy and/or thermal energy, in order to reduce forces, in particular forces acting on a child in the infant seat. In this context, an "energy absorption unit" is to be understood to mean, in particular, a unit which, on the basis of its material properties, can absorb, in particular convert, energy, in particular kinetic energy, for example rotational energy, translational energy, particularly well from a component which is in contact with the energy absorption unit. Thus, the child seat system can be constructed in a particularly safe manner.

It is also proposed that the infant seat be provided for providing at least two different reclining angles, wherein the infant seat is configured non-mechanically here. In this context, the term "reclining angle" is to be understood to mean, in particular, the angle between the base on which the infant seat is arranged and the back region of the infant seat, against which the child reclining in the infant seat rests with its back. In this context, "at least two different reclining angles" are to be understood in particular to mean that with the infant seat it is possible to provide two reclining positions for a child, wherein the child can be oriented at different angles relative to the floor and/or the base module. Here, "non-mechanical" is to be understood in particular to mean that the infant seat is configured without mechanical means for achieving an adjustment of the reclining angle. It is therefore particularly advantageous that the infant seat can be constructed to be light.

It is also proposed that the infant seat is formed at least in some regions by a housing, in particular a plastic housing, which has a wall thickness of less than 2 mm. Advantageously, the plastic housing has a wall thickness of less than 1.5 mm. The wall thickness is understood here to mean the entire plastic housing. Thereby, the infant seat can be constructed particularly light.

It is also proposed that the base module has a width of less than 440 mm. The child seat system can thereby be constructed particularly advantageously and in accordance with ECE standard R129.

The child seat system according to the invention should not be limited to the applications and embodiments described above. In particular, the child seat system according to the invention has a number different from the number of the individual elements, components and units mentioned therein in order to achieve the functional manner described therein.

Detailed Description

Fig. 1 to 4 show a design of a child seat system according to the invention. Child seat systems are provided to safely transport children, particularly young children, in motor vehicles.

Child seat systems are provided for safely transporting an infant or young child in a motor vehicle. The child seat system includes an infant seat 10. The infant seat 10 is provided for transporting an infant. An infant or young child may be transported in the infant seat 10 in a substantially recumbent manner. The child seat system includes a base module 12 configured to be fixedly coupled within a motor vehicle. The base module 12 is configured to be separated from the infant seat 10. The base module 12 is provided for attachment to a motor vehicle seat and/or a motor vehicle bench seat in a fixed and travel-safe manner. The base module 12 includes a base 14. The base 14 is configured as a support structure for the base module 12. The base module 12 has a bearing 16 at the front end of the base 14. The bearing block 16 is provided to support the base module 12 at the floor of the motor vehicle, in particular in the foot region of the motor vehicle. The base module 12 has a form-fitting element 18 at the rear end of the base module 12, by means of which the base module 12 can be fixedly connected to a support structure of a motor vehicle, in particular of a motor vehicle seat on which the base module 12 is arranged. The form-fitting element 18 is designed here as an ISOFIX connector. The form-fitting element 18 and the bearing block 16, which are designed as ISOFIX connectors, are known from the prior art and are designed accordingly, so that a detailed description thereof is omitted. For transport in a motor vehicle, the infant seat 10 is arranged in a fixed connection with a base module 12 connected in the motor vehicle. For this purpose, the base module 12 has a connection unit in the interior region of the base body 14 of the base module 12. The connection unit, which is not shown in detail, is constructed from a plurality of form-fitting elements by means of which the infant seat 10 can be coupled form-fittingly with the base module 12. For this purpose, the infant seat 10 has a correspondingly configured connection unit at its underside. The infant seat 10 can be inserted from above into the base body 14 of the base module 12 and be positively coupled to the base module 12 by means of a connecting unit. Here, the infant seat 10 is coupled with the base module 12 in a transport-safe manner. To couple the infant seat 10 with the base module 12, the infant seat 10 is first inserted into the base module 12 at a prescribed location. The defined position is achieved by form-fitting elements in the base module 12, into which the infant seat 10 is inserted by means of correspondingly configured form-fitting elements in the base module 12. The infant seat 10 is then tilted relative to the base module 12 and is in this case locked fixedly with the base module 12. Advantageously, the infant seat 10 is here rotated about the form-fitting element for positioning. The infant seat 10 is thereby coupled particularly simply and safely with the base module 12. In particular in the event of a crash in which a high force acts on the base module 12 and the infant seat 10, the infant seat 10 remains securely and fixedly coupled with the base module 12.

The infant seat 10 has a weight of 4kg or less. The infant seat 10 has a weight of 3.7 kg. In particular, the infant seat 10 together with all the components that stabilize the infant seat 10 when used outside of the base module 12 has a weight of 3.0 kg. The weight of the infant seat 10 is measured particularly in a state where the infant seat 10 is separated from the base module 12. In particular, the weight of the infant seat 10 is measured along with all of the elements of the infant seat 10 that are required to apply the infant seat 10 outside of the motor vehicle, outside of the base module 12. Here, elements that are formed by the infant seat 10 and take into account the weight of the infant seat 10 are explained below. The list of elements of the infant seat 10 is not to be regarded as complete here, since the infant seat 10 may, of course, also have other elements or components.

The infant seat 10 has a base 20. The base 20 of the infant seat 10 is formed from a plastic shell. The base body 20 of the infant seat 10 is formed by a housing, in particular a plastic housing. The base 20 of the infant seat 10 has a wall thickness of 1.5 mm. The infant seat 10 has an integrated harness system 22. The integrated seat belt system 22 is configured as a three-point seat belt. The internal safety belt system 22 is in particular designed as a Y-belt, which in particular has two shoulder belts and a step belt, which can be connected to one another by means of a belt buckle. In principle, it is conceivable to configure the internal seat belt system 22 as a five-point seat belt. An integrated harness system 22 is provided for securing a child in the infant seat 10. The infant seat 10 has a cushion unit 24. The cushion unit 24 is connected to the base body 20 of the infant seat 10. The cushion unit 24 is configured as a support surface for the infant seat 10. Here, the cushion unit 24 is formed of a foamed plastic. The cushion unit 24 has a removable, not shown in detail, liner. In principle, it is also conceivable to construct the cushion unit 24 in another way which is meaningful to the person skilled in the art. The infant seat 10 includes a shock absorber 28 that is optionally incorporated into the infant seat 10. The shock absorber 28 is disposed on the reclining surface and incorporated into the infant seat 10 to match the angle of the infant seat 10 and the size of the reclining area of the infant seat 10 to the infant. Shock absorber 28 is made of foam. The shock absorbers 28 can be coupled with the infant seat 10 in a loss-proof manner.

The infant seat 10 has a carrying handle 26. The handle 26 is adjustable between at least two positions. The handle 26 is adjustably attached to the base 20 of the infant seat 10. In particular, the handle 26 is pivotally connected to the base 20 of the infant seat 10. Handle 26 is configured to be substantially U-shaped. Handle 26 has a substantially U-shaped curve. Handle 26 extends from a first side of base 20 to an opposite second side of base 20. Handle 26 has two side parts extending parallel to each other. The first side part is arranged on a first side of the base body 20 and the second side part is arranged on a second, opposite side of the base body 20. The side elements of handle 26 are configured substantially identical to one another. The side parts of the carrying handle 26 are each connected with a first end to the base body 20 of the infant seat 10. The first ends of the side parts of the carrying handle 26 are each connected to the base body 20 of the infant seat 10 via a pivot bearing. The side pieces are connected to each other at the second end by means of the connecting piece of the handle 26. The connecting member extends from the first side member to the opposite second side member. The connecting member spans the base 20 of the infant seat 10. The side members and connecting members form a handle 26. The side members and the connecting member are integrally constructed with each other. The connecting part is configured as a gripping area which is arranged to be gripped by a person for carrying the infant seat 10. In principle, a rigid connection of the carrying handle 26 to the infant seat 10 is also conceivable. In the event of a side impact, the handle 26 is provided with the base module 12 to absorb impact energy. For this purpose, the handle 26 is in particular designed to be rigid, so that it is substantially undeformed in the event of a side impact. In principle, it is also conceivable for the handle 26 to be arranged so as to be slightly elastically deformable in the event of a side impact, in particular to absorb impact energy. Here, handle 26 is deformed back to its original shape again after the impact. In particular, the carrying handle 26 is arranged such that, in the event of a side impact, forces acting laterally on the infant seat 10 are guided via the side parts and the connecting parts around a child lying in the infant seat 10.

The infant seat 10 is configured to provide two different reclining angles 30, 32. In principle, it is also conceivable that the infant seat 10 is provided for providing three or more different reclining angles. The different reclining angles 30, 32 are designed here as angles enclosed by the base on which the infant seat 10 is arranged and the back region of the infant seat 10, in particular the reclining surface of the infant seat 10. The first reclining angle 30 is here 40 degrees. Second reclining angle 32 is here 55 degrees. The infant seat 10 is not mechanically configured to provide different lie angles 30, 32. In order to provide the different reclining angles 30, 32 non-mechanically, the infant seat 10 has two different rest areas 34, 36. The rest areas 34, 36 are provided for the infant seat 10 to be supported on a base. Depending on which of the placement regions 34, 36 the infant seat 10 is placed on the base, the lying surfaces of the infant seat 10 are oriented differently and thus form different lying angles 30, 32. The rest areas 34, 36 here form three contact areas, respectively, in which the infant seat 10 rests on the base. In particular, the infant seat 10 has a first lie down angle 30 when properly secured in the base module 12. The infant seat 10 optionally has a reclining angle 30 or 32 in a state where the base is positioned outside of the base module 12. In principle, it is also conceivable that the infant seat 10 can be placed only at the second reclining angle 32 when it is placed outside the base module 12, so that the infant seat 10 can be arranged only at the reclining angle 30 corresponding to the position in which it is arranged in the base module 12 and at the reclining angle 32 corresponding to the position in which it is placed outside the base module 12.

Functional and/or safety elements 38, 40, 42 required for transport in the motor vehicle are arranged at the base module 12. Preferably, all functions and/or safety elements 38, 40, 42 which are not required for transporting children outside the motor vehicle are arranged at the base module 12. The safety element 38 is configured as a front impact protection. The safety element 38 forms a front region of the base module 12. The safety element 38 extends from a lower region of the base module 12, with which the base module 12 rests on the motor vehicle seat, into an upper region in which a head region of the infant seat 10 is arranged in the state in which the infant seat 10 is arranged in the base module 12. The safety element 38 is formed obliquely. The security element 38 has a height of 245 mm. In principle, it is also conceivable for the safety element 38 to have a height of between 350mm and 150 mm. By means of the safety element 38, which is formed integrally with the base module 12, the base module 12 absorbs at least a large part of the impact energy in the event of a frontal impact.

The safety element 40 is configured for frontal side impact protection. The safety element 40 is constructed integrally with the base module 12. In the state in which the infant seat 10 is arranged in the base module 12, the safety element 40 is arranged between the first safety element 38, which constitutes front crash protection, and the carrying handle 26 of the infant seat 10. The second safety element 40 forms a side impact protection on both sides in the shoulder region of the infant seat 10. The safety element 40 forms the opposite side wall of the base module 12 in the shoulder region of the infant seat 10. The safety element 40 extends from a lower region of the base module 12 into a shoulder region of the infant seat 10.

The safety element 42 is configured for rear side impact protection. The safety element 42 is constructed integrally with the base module 12. In the state in which the infant seat 10 is arranged in the base module 12, the safety element 42 is arranged between the rear end of the base module 12, at which the form-fitting element 18 is arranged to be coupled with the motor vehicle seat, and the carrying handle 26 of the infant seat 10. The third safety element 42 forms a side impact protection on both sides in the hip region of the infant seat 10. The safety element 42 forms the opposite side wall of the base module 12 in the hip region of the infant seat 10. The safety element 42 extends from a lower region of the base module 12 into a hip region of the infant seat 10. In a state in which the infant seat 10 is arranged in the base module 12, the safety elements 40 and 42 substantially cover the shoulder and hip areas of the infant seat 10.

The child seat system includes a first energy absorbing unit 44. The child seat system includes a second energy absorbing unit 46. In principle, it is also conceivable for the child seat system to have further energy absorption units 44, 46. The energy absorbing units 44, 46 are arranged between the base module 12 and the infant seat 10. The first energy absorption unit 44 is arranged here on a first inner side of the base module 12. A second energy-absorbing unit 46 is arranged on a second, opposite inner side of the base module 12. The energy absorbing units 44, 46 are fixedly connected to the base module 12. The energy absorption units 44, 46 are arranged for converting impact energy, in particular impact energy into deformation energy. The energy absorbing units 44, 46 are arranged to reduce acceleration forces acting on a child lying in the infant seat 10 in a collision. Advantageously, the energy absorption units 44, 46 are configured as a U-shaped frame which in the mounted state surrounds the infant seat 10 at least laterally and on the rear side. Advantageously, the two energy absorption units 44, 46 are integrally formed with one another. Preferably, the energy absorbing units 44, 46 configured as U-shaped frames are formed of an energy absorbing material, such as foam or other deformable material that is meaningful to one skilled in the art. In principle, it is also conceivable for the energy absorption units 44, 46 to be designed in other ways that are meaningful to the person skilled in the art, for example as airbag elements which are triggered in the event of a crash and are at the same time filled with gas in particular.
