A vehicle including illuminated stitching as a trim on a vehicle interior surface. The method for installing the illuminated stitching includes cutting a continuous channel into the vehicle interior surface. The method also includes installing an illuminated fiber into the channel. The illuminated fiber is at least partially exposed and emits light. The illuminated fiber is secured in the channel to ensure the fiber stays in the channel.

A fastener assembly includes an insert and a base. The insert has a first plurality of teeth. The base defines a cavity to receive the insert and includes a second plurality of teeth to engage with the first plurality of teeth.

Doors for motor vehicles include door trim panel assemblies having multiple door trim panels held together at attachment points. A door trim panel includes a weakened perimeter formed from a series of apertures in the panel, creating a predetermined breakaway point where the assembly will rupture in the event a load is applied. Methods for tuning the durability of a trim panel assembly include a repeatable cycle in which pins are selected and inserted in a mold at varying positions. During injection molding, the pins form apertures to create a predetermined breakaway point. Changing the size, shape, and location of the pins allows tuning of the durability and properties of the breakaway point. Injection molds have variable pin placement capability to facilitate the method.

Quarter turn clip for connecting a vehicle metal sheet plate and an expanded polypropylene vehicle panel, and quarter turn clip and expanded polypropylene vehicle panel assembly. The quarter turn clip is able to perform the sealing and pre-mounting functions despite it comprise neither a sealing ring in order to ensure the sealing function nor additional pre-mounting elements in order to pre-mount the quarter turn clip into the expanded polypropylene vehicle panel.

A clip mounting seat includes a mounting base having an outer edge, a mounting hole, and a mounting base-side insertion opening that is included at a part of a hole edge of the mounting hole and through which the clip is inserted to the mounting hole, a wall extending downward from the outer edge and including an insertion-side wall having a wall-side insertion hole communicated with the mounting base-side insertion opening, and a guide member included in the insertion-side wall and extending toward the mounting hole and being adjacent to the wall-side insertion hole and opposite the mounting base-side insertion opening with respect to an insertion direction of the clip. The guide member guides the clip and includes an end portion that is opposite the mounting base-side insertion opening and has a thickness greater than a distance between a leg portion and a support portion of the clip.

A vehicle interior component includes a base portion in which a trench is formed, a skin portion on which a seam allowance portion stitched with a main seam is provided and which is wrapped around the base portion, an auxiliary portion that is interposed between the seam allowance portion and the trench, and a decoration seam that is formed in the skin portion in a manner that is in parallel with the seam allowance portion centerline, in which at least one of a first guidance means with which the auxiliary portion aligns with the base portion and a second guidance means with which the decoration seam aligns with the auxiliary portion is provided on the base portion.

A component system for fixing a trim part in a defined position as well as a motor vehicle, in particular a passenger car, is provided. The component system has a trim part that is to be fixed in relation to a motor vehicle body component, in particular a headliner, a trim support for supporting the trim part as well as a counter-pressure device for applying a first force to a first area of the trim part. At least one section of the trim support is disposed on a side of the first area opposite the counter-pressure device for applying a second force oriented in an opposite direction from the first force to the first area. A second area of the trim part is disposed on the side of the trim support opposite the first area and thus forms a visible side of the trim part.

An assembly of mating subassemblies having dimensional control features for a motor vehicle is provided. The assembly includes a composite molded first subassembly having a first set of molded-in dimensional control features. The assembly also includes an injection molded second subassembly having a second set of molded-in dimensional control features. The first and second sets of dimensional control features are integrally formed on their respective subassemblies to permit contact between the first and second sets of control features when the subassemblies are assembled together.

A sewn covering for covering support parts includes at least one first and at least one second trim cover element which are connected to one another via a functional seam. A soft insert runs along at least some sections of the functional seam. The seam stump formed by the functional seam can be surrounded by a seam band which can be fixed by the functional seam. To produce such a sewn covering, a band can be used which has an at least partially elastic seam band that is perforated in the longitudinal direction. At least one soft insert is provided in the longitudinal direction of the partially elastic seam band, which insert is fixed to the seam band.
