Technical Field

The present invention relates to a roller shutter assembly for a vehicle. Further, a method for manufacturing a roller shutter assembly for a vehicle is provided.

Background

Roller blind assemblies (also referred to as shade devices) having a roller blind web are known for use in vehicles. Such roller blind assemblies are used, for example, to protect against sunlight under transparent sections of the vehicle, such as under light-transmitting portions of the roof. Such a roller shutter assembly is described, for example, in EP 1006012 a 2.

It is desirable to provide a roller shade assembly for a vehicle that enables reliable operation. Furthermore, it is desirable to provide a method for manufacturing a roller shutter assembly for a vehicle, which method can be reliably implemented.

Disclosure of Invention

The invention provides a roller shutter assembly for a vehicle roof. Furthermore, a method for manufacturing a roller blind assembly for a vehicle, in particular for manufacturing a roller blind assembly as described herein, is provided. The advantages, features and improvements of the roller blind arrangement correspondingly also apply to the method and vice versa.

According to at least one embodiment, the roller blind assembly has a roller blind web. The rolling web can be rolled up and unrolled in the longitudinal direction. The roller blind web can thus be changed in particular between a stowed position in which it is rolled together and a functional position in which it is unrolled.

The roller blind assembly has a plastic guide strip. The guide strip is connected to the roller blind web in the edge region of the roller blind web in the longitudinal direction. The plastic guide strip consists of plastic or at least substantially, in particular at least 90%, consists of plastic. The plastic guide strip (also referred to as guide strip or plastic strip in the following) is flexible in order to be rolled up and unrolled together with the roller blind web.

The roller blind assembly has a driver. The driver and the plastic guide strip are rigidly coupled to each other relative to each other along the longitudinal direction. In particular, no significant relative movement between the driver and the plastic guide strip in the longitudinal direction can be achieved in the ready state.

The roller shade assembly has a roller shade coupler. The roller blind coupling may be coupled with a driver. The coupling between the roller blind coupling and the driver makes it possible to drive the drive device by means of the driver and the roller blind coupling on the plastic guide belt.

The connection between the driver, the roller blind coupling and the guide strip is designed in such a way that a force flow from the driver and the roller blind coupling to the plastic guide strip can occur during operation. When the drive moves the roller blind coupling and/or the driver, this movement is transmitted directly to the guide belt. The drive therefore also directly moves the guide belt. This is not the case, for example, if the guide strip is connected to the roller blind coupling only indirectly via the roller blind web and, for example, the pull bracket. The drive actively moves the elements guided in the guide rails, i.e. the guide belt and the roller blind coupling, respectively.

The coupling of the guide belt to the drive enables a large pull-out length, since the increased friction of the guide belt in the guide rail can also be overcome. Thus, especially when winding up the roller blind web, compression of the guide belt can be avoided. During the handling of the roller blind assembly, a corrugation and/or a wrinkle formation of the roller blind web, in particular in the attachment region, can be avoided. Attaching the guide strip to the roller blind coupler enables higher material stresses of the roller blind web than in conventional roller blind assemblies in which the lateral guide is not attached to the coupler. Therefore, despite a large rolling screen area, an increase in sag can be avoided. Overall, therefore, reliable operation of the roller blind assembly can also be achieved over a relatively long service life. Due to its increased robustness, the possible opening/closing cycles of the roller blind assembly can be increased, in particular in comparison with conventional roller blind assemblies.

According to at least one embodiment, the driver protrudes transversely to the longitudinal direction from the roller blind web. Thus, a simple and reliable locking in the longitudinal direction can be achieved.

According to at least one embodiment, the roller blind assembly has a sewn connection. The sewn connection connects the plastic guide strip and the roller blind web to each other. Other attachment means, such as ultrasonic welding or adhesive bonding, may also be used.

According to at least one embodiment, the plastic guide strip is directly connected to the roller blind web in a material-locking manner. In particular, the connection between the guide strip and the roller blind web is constructed directly during the manufacture of the guide strip. The guide strip is produced in such a way that it is directly connected to the roller blind web during production in a material-locking manner. For example, plastic guide tapes are printed directly onto the roller blind web by means of additive manufacturing. It is also possible for the guide strip to be sprayed directly onto the roller blind web by means of extrusion or injection molding. In the extrusion method, the tool part is moved relative to the injection nozzle during the injection of the plastic. Different connection means may also be combined.

According to at least one embodiment, the plastic guide strip and the driver are formed integrally with one another. The guide belt and the driver are jointly manufactured. For example, the driver is printed by means of additive manufacturing or manufactured by means of an extrusion or injection molding method. This enables fewer process steps for manufacturing. Fewer individual components may also be implemented. This also makes it possible to reduce the installation space requirement, since the installation space requirement for connecting the driver to the guide belt is eliminated. In operation, due to the design of the driver and the plastic guide strip, a better force absorption can be achieved in a common step.

According to at least one embodiment, the plastic guide strip and the driver are configured as separate components from one another. The roller blind assembly has a plastic connecting part for connecting the plastic guide belt and the driver to each other. The plastic connecting part has, for example, at least in regions, a molded part of the plastic guide strip and/or the driver, in order to form a force-locking and/or form-locking and/or material-locking plastic connecting part between the guide strip and the driver.

According to at least one embodiment, the roller blind coupling has a snap connection. The snap connection serves to couple the driver and the roller blind coupling to one another. It is possible to press the driver into the roller blind coupling by means of a relative movement in the longitudinal direction. The snap connection can be pressed in. The snap connection then engages behind the driver, preventing relative movement in the longitudinal direction.

According to at least one embodiment, the driver is part of the attachment portion of the drive cable. The roller blind coupling can be coupled to the attachment of the drive cable by means of a catch. The attachment is in particular a plastic injection-molded part or a plastic foam part of the drive cable. The driver is directly attached to the drive cable. No relative movement between the driver and the drive cable is possible. The catch is used for attaching the roller blind coupling and for attaching the guide belt to the drive cable.

According to at least one embodiment, the driver is directly fixed to the roller blind coupling. The catch engages directly into a corresponding recess of the roller blind coupling. In operation, therefore, the transmission of force can take place without additional intermediate elements.

According to at least one embodiment, a method for manufacturing a roller shade assembly includes providing a roller shade web having a plastic guide strip. The plastic guide strip is coupled to the roller blind web in the edge region of the roller blind web in the longitudinal direction. The driver and the plastic guide strip are rigidly coupled to each other relative to each other along the longitudinal direction. A roller shade coupling is provided. The roller blind coupling may be coupled to a drive device. The roller blind coupling, the catch and the plastic guide strip are coupled to one another, so that a drive movement of the drive can be transmitted to the plastic guide strip by means of the catch and the roller blind coupling.

It is possible that the roller blind coupling is first connected to the drive cable of the drive device and the driver is connected to the plastic guide strip. Subsequently, the driver is connected to the roller blind coupling.

It is also possible that the roller blind coupling is first directly connected to the plastic guide belt and the driver is first directly connected to the drive cable. Subsequently, the driver and the roller blind coupling are connected to one another.

According to at least one embodiment, the plastic guide strip is manufactured by means of an extrusion or injection molding method. For example, the driver is produced together with the plastic guide strip by means of an extrusion or injection molding method.

Alternatively or additionally, the plastic guide strip is manufactured by means of additive manufacturing, also known as 3D printing. For example, the driver is produced together with the plastic guide strip by means of additive manufacturing.

According to at least one embodiment, the driver is made of plastic. The plastic of the driver is deformed for fixing the driver and the plastic guide strip to each other. Alternatively or additionally, the roller blind coupling is made of plastic. The plastic of the roller blind coupling is deformed for fixing the roller blind coupling and the plastic guide strip to one another. The desired rigid connection between the individual elements can thus be established by means of deformation of the plastic.

Detailed Description

Fig. 1 shows a schematic view of a vehicle 100 having a roof 101 provided with a roof opening 102. The roof opening 102 can be closed by means of a cover 131. The cover 131 is, for example, a movable cover which is movable relative to the rest of the roof 101 in order to at least release the roof opening 102. Alternatively, the cover 131 is rigidly connected to the rest of the vehicle roof 101, for example as a so-called fixed glass element. The cover 131 is at least partially transparent or translucent so that light can pass from the outside through the cover 131 into the interior space of the vehicle 100.

The positional and directional information used, such as rear or front, upper or lower, left or right, relate to the longitudinal axis of the vehicle and to the general direction of travel of the vehicle 100 ready for operation.

The guide rails 104 are connected to the roof 101 on both sides of the roof opening 102. The roller shade assembly 110 is at least partially retained by the guide rail 104. The rolling shutter assembly 110 has a rolling shutter web 111. The rolling shutter web 111 is disposed below the cover 131 and faces the interior space of the vehicle 100.

The rolling web 111 may be wound and unwound from the roller 121 along the longitudinal direction 107. The rolling web 111 may be moved forward and backward along the longitudinal direction 107, so that the rolling web 111 is rolled up and unrolled. The longitudinal direction 107 extends substantially parallel to the longitudinal axis of the vehicle 100.

The roller shade web 111 and the roller shade assembly 110 are used to allow sunlight and ambient light to enter the vehicle 100 through the roof opening 102 or to reduce sunlight and ambient light from entering the vehicle.

The roller blind web 111 is guided in the side rails 104 or at least extends between these when being rolled up and unrolled. A pull frame 108 is arranged on a first end 122 of the roller blind web 111 facing the windshield 109 of the motor vehicle. The traction frame is coupled with a drive device 105 by means of a drive cable 106. The driving device 105 has, for example, a motor. The drive movement of the drive device 105 is transmitted by means of the drive cable 106 to the pull carriage 108 in order to wind up and unwind the roller blind web.

An inverted configuration is also possible, in which the drive device 105 is arranged on the side facing the windshield 109 next to the roof opening 102 and the first end 122 of the roller blind web faces the oppositely arranged rear window. Alternatively or additionally, the roller blind assembly 110 is used to cover another opening in the body of the vehicle 100.

Only one side of the roof opening 102 is shown in each of the figures described below. The opposite side is correspondingly configured and is not explicitly explained separately below.

FIG. 2 illustrates a schematic view of a portion of a roller shade assembly 110 according to one embodiment. Fig. 3 and 4 respectively show a sectional view of the roller blind assembly 110 according to fig. 2.

The roller shade assembly 110 has a plastic guide strip 112. The plastic guide strip 112 is connected to the roller blind web 111 in the edge region 113. For example, the plastic guide strip 112 is connected to the roller blind web 111 by means of a sewn connection 117. For example, the plastic guide strip 112 and the roller blind web 111 are connected to each other by means of stitching. The edge region 113 adjoins in particular the side edge 114 of the roller blind web 111 directly.

The plastic guide strip 112 is guided in the guide rail 104. The guidance in the longitudinal direction 107 of the roller blind web 111 and the tensioning in the Y direction can be achieved by means of a plastic guide strip 112 (which is also referred to below as plastic strip or guide strip).

At the first end 122, the driver 115 is connected to the guide belt 112. As shown, for example, in fig. 3, the driver 115 according to an embodiment has a protruding region 119. The protruding region passes through a recess, not explicitly shown, of the guide strip 112 in the Z-direction. A plastic connection 118 is formed on the projection 119 in order to connect the driver 115 to the guide band 112 in such a way that they are immovable relative to one another at least in the longitudinal direction 107.

According to an exemplary embodiment, two or three recesses, for example holes, are provided in the guide strip 112, and a corresponding number of projecting regions 118 are formed on the driver 115. For the purpose of forming the plastic connection 118, the projection regions 119 are, for example, each at least partially thermally deformed, for example, pressed flat. Alternatively or additionally, the driver 115 can be connected to the guide band 112 by means of ultrasonic welding. The plastic connection 118 can also be formed by means of ultrasonic welding.

The driver 115 has an engagement element 126. The engaging elements 126 project in the Z direction. The engagement elements 126 are exposed from the rail 104. The engagement element 126 is configured for engagement with the roller blind coupler 116.

The roller blind coupling 116 is guided in the guide rail 104. The roller shade coupler 116 is attached directly to the drive cable 106. For example, a roller shade coupling 116 made of plastic is injection molded directly onto the drive cable 106.

In order to fix the driver 115 to the roller blind coupling 116, the roller blind coupling 116 has a snap connection 120. The snap connection 120 has a flexible leg 124 with a nose 123. In order to mount the driver 115 on the roller blind coupling, the driver 115 is moved in the longitudinal direction 107 relative to the roller blind coupling 116. This movement causes a pivoting of the flexible leg 124, which can then cause the engagement element 126 of the driver 115 to enter into the snap connection 120. To this end, the roller blind coupling has a recess 125, which releases the movement of the leg 124. Once the engagement element 126 is in its operative position, the flexible leg 124 moves back to its initial position. The nose 123 engages behind the engagement element 126, so that a relative movement between the driver 115 and the roller blind coupling 116 in the longitudinal direction 107 is prevented.

Thus, in the roller shutter assembly 110, the guide belt 112 is attached to the drive device 105 by means of a rigid element. In contrast, in conventional roller blind assemblies without the driver 115, the guide belt can be moved only indirectly by means of the roller blind web 111. The roller shade assembly 110 described herein enables the guide strip 112 to move directly relative to the guide rail 104 regardless of movement of the roller shade web 111 or the roller shade material. The guide belt 112 together with the roller blind coupling 116 is moved directly driven by the drive cable 106 relative to the guide rail 104. The force introduction to the guide belt 112 is not effected primarily by the roller blind material of the roller blind web 111, but primarily by means of the driver 115.

The driver 115 is designed, for example, as a plastic injection-molded part. The driver 115 is connected to the plastic guide band 112. The plastic guide strip 112 constitutes a lateral guide made of plastic. For assembly, the driver 115 is snapped into the roller blind coupling 116. The roller shade coupling 116 is injection molded onto the drive cable 106. The pulling yoke 108 is preassembled on the roller blind material of the roller blind web 111. The pull carriage 108 snaps into the roller blind coupling 116, for example, by means of a rotational movement. It is thus possible for the roller blind assembly 110 to be fitted in the region of the guide rail 104 in which the roller blind coupling 116 is already arranged.

Fig. 5, 6 and 7 show a roller shade assembly 110 according to another embodiment. The roller blind assembly 110 substantially corresponds to the embodiment of fig. 2 to 4. The differences are mainly discussed below.

In the exemplary embodiment according to fig. 5 to 7, the guide band 112 is produced together with the driver 115, in particular the engagement element 126 of the driver 115. For example, the guide belt 112 and the driver 115 are manufactured by means of 3D printing. Alternatively or additionally, the guide band 112 and the driver 115 are produced by an extrusion method or injection molding. For example, the guide strip is deposited directly as an elongated flat geometry onto the roller shade fabric of the roller shade web 111. In the 3D printing and extrusion method, the injection molding is carried out with a cavity that can be successively enlarged and reduced, which makes it possible to jointly produce the guide band 112 and the driver 115 with different degrees of extensibility from one another, in particular in the Z direction. Therefore, an additional plastic connection 118 for connecting the driver 115 and the guide band 112 can be omitted. Thus, fewer process steps are required for manufacturing. Fewer components are generally required. In operation, good force absorption can be achieved by forming the driver 115 and the guide belt 112 in one common step. Furthermore, in the region of the guide rail 104, installation space can be reduced by omitting the plastic connection 118 below the location for assembling the roller blind assembly 110 on the guide rail.

Fig. 8, 9 and 10 show a roller shade assembly 110 according to another embodiment. The basic operation corresponds to the embodiment of the figures described so far. The differences are mainly discussed below.

The driver 115 is not directly fixed to the guide belt 112. The catch 115 is part of the attachment 103 to the drive cable 106. The attachment portion 103 is injection molded directly onto the drive cable 106 along with the driver 115. The drive cable 106 forms a structural group together with the attachment portion 103 with the driver 115.

The roller shade coupler 116 has one or more tabs 128. The tab 128 is used to connect the roller shade coupler 116 with the guide belt 112. The guide strip 112 is therefore directly connected to the roller blind coupling 116, for example by means of a plastic connection, such as thermoforming or ultrasonic welding, or another connection type. The roller blind coupling 116 is therefore first connected to the guide strip 112.

The roller shade coupler 116 has a recess 127. The recess 127 corresponds in its shape to the driver 115. For example, the driver 115 and the recess 127 are configured as a loss prevention device. In the embodiment shown, a dovetail shape is configured. This enables the roller blind coupling 116 to be inserted onto the driver 115 in the Z direction. In the assembled state, however, a relative movement between the driver 115 and the roller blind coupling 116 in the longitudinal direction 107 is prevented.

Fig. 9 shows the mounting region 129 in front of one end of the guide rail 104. At this mounting region, the roller blind coupling 116 can be plugged onto the driver 115. The driver 115 is then moved together with the roller blind coupling 116 and possibly the pull rail 108 (not shown in detail) into the guide rail 104. The mounting region is closed with a closure 130 (fig. 10) in order to prevent the roller blind coupling 116 from unintentionally falling out of the guide rail 104. Alternatively or additionally, the closure 130 also serves to guide the centering of the belt 112.

The embodiment according to fig. 8 to 10 thus makes it possible to assemble the roller blind coupling 116 with the driver 115 outside the guide rail 104. The roller shade coupling 116 transmits the movement force directly to the draw frame 108 and the guide belt 112.

The rolling shutter assembly 110 according to various embodiments can allow the rolling shutter web 110 to have a drawn-out length of up to 2m or more while maintaining aesthetic regulations. Higher material stresses are possible. A better appearance of the roller blind web 111 in the pulled-out state can be achieved, since a smaller material sag is achieved. The roller blind web 111 can be assembled and disassembled with the guide rails 104 in the installed state in the vehicle roof 101 by means of the pull frame 108. According to embodiments, a specific mounting location for the roller shade coupler 116 outside the guide rail 104 may be omitted. Therefore, the installation space can be saved along the longitudinal direction 107. The firmness of the roller shade assembly 110 may be improved. A longer service life or more winding/unwinding cycles can be achieved. Due to the direct movement of the guide belt 112 by means of the driver 115, the high friction on the guide belt 112, which occurs, for example, when the pull-out length increases, is overcome.

The coupling of the driver 115 to the roller blind coupling 116 is coordinated in such a way that a relative movement between the driver 115 and the roller blind coupling 116, which could produce a click sound, is avoided. For example, the engagement element 126 is configured to slightly interfere such that it is securely tensioned in the roller blind coupler 116. Other types of tolerance compensation are also possible, in particular by means of the driver 115 and the roller blind coupling 116 being geometrically coordinated with one another.
