Technical Field
This document relates generally to the field of automotive equipment and, more particularly, to a new and improved fastening system for securing trim panels to a support substrate and, more particularly, for securing door trim panels to a door inner panel.
Background
During a side impact event, the laterally intruding movement of the vehicle can cause severe deformation of the door sheet metal. Door trim panels that are directly attached to the door sheet metal via conventional mechanical fasteners such as plastic clips, thumbtacks, metal clips, etc. may not be able to overcome the door sheet metal deformation and the door trim panel may separate away from the door sheet metal toward the passenger seat location. This separation can adversely affect vehicle horizontal performance, including, for example, proper deployment of the side airbag.
This document relates to a new and improved fastening system that improves the integrity of the connection between a door trim panel and a supporting base panel or door inner panel. Advantageously, the enhanced integrity of this connection serves to counter side impact energy and associated vehicle lateral intrusion movement resulting from a side impact without performing any intensive body side structural upgrade that would require, for example, increased B-pillar reinforcement, thickened B-pillars, door impact beams, and the like. While effective, such body side structural upgrades increase the cost and weight of the vehicle, which will adversely affect the overall fuel economy performance of the vehicle. Advantageously, these disadvantages are avoided by using the new and improved fastening system, which is also completely hidden from view and does not adversely affect the aesthetic appearance of the door trim.
Disclosure of Invention
In accordance with the objects and benefits described herein, a new and improved trim piece fastening system is provided. The fastening system is particularly suitable for securing a door trim panel to a support substrate, such as a door inner panel of a motor vehicle door.
The fastening system includes a locking pin, a dog house structure including a receiver, and a retainer body retained in the receiver. The retainer body includes a retention feature adapted to receive and retain the locking pin.
The retainer body may include a spring clip at the front end. The retention feature may include a locking aperture that receives the locking pin. The locking hole may have a first diameter D1。
The spring clip may include a first cantilever arm and a second cantilever arm. Further, the retainer body may include a stop at the rear end opposite the spring clip at the front end. When the retainer body is properly seated in the receptacle of the kennel structure, the spring clip may engage a first sidewall of the kennel structure at a first end of the receptacle and the stop may engage a second sidewall of the kennel structure at a second end of the receptacle.
The locking pin may include a seating flange, an anchoring end on a support substrate side of the seating flange, and a dog house-like structure end on a decorative component side of the seating flange. More specifically, the anchoring end may include an enlarged base. The dog house structure may include a head and a handle. The handle may be disposed between the head and the seating flange.
The head may have a second diameter D2Wherein D is1>D2. The shank may have a third diameter D3Wherein D is1>D2>D3. When the locking pin is properly secured in the retainer body, the shank passes through the locking hole. According to a further aspect, a method for securing a trim component to a door inner panel is provided. The method comprises the following steps: (a) securing the locking pin to the door inner panel, (b) providing a dog house structure onto the trim component, (c) inserting the retainer body into a receptacle in the dog house structure, and (d) engaging the locking pin with the retention feature of the retainer body.
The method may also include the step of sliding the retainer body into the receiver such that the shank of the locking pin engages a rim of the retainer body defining the retention feature. Additionally, the method may further include the step of capturing the head of the retaining pin with a rim of the retainer body extending around and defining the retaining feature.
In addition, the inserting step may be performed in a first direction and the sliding step may be performed in a second direction, wherein the first direction is perpendicular to the second direction. The perpendicular relationship between the orientation of the insertion action and the orientation of the sliding action serves to greatly improve the integrity of the connection between the locking pin and the retainer body and, therefore, the connection of the door trim panel to the inner door panel.
In the following description, several preferred embodiments of a fastening system and associated method of securing a decorative bread component to a door inner panel are shown and described. It will be appreciated that the fastening system and associated method are capable of other different embodiments and its several details are capable of modification in various, obvious aspects, all without departing from the fastening system and method as set forth and described in the following claims. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.
