The present invention relates to a plastic vehicle-interior-part with an impact module.
Plastic vehicle-interior-parts often comprise impact modules, which are used as internal features to prevent excessive deflection of plastic vehicle-interior-parts, for example the valance of a vehicle seat. The impact module's functionality is, for example, to prevent the side valance from deflecting more than 10 mm when subjected to a dynamic seat belt test.
It is therefore the objective of the present invention to provide a plastic vehicle-interior-part with an impact module.
The problem is solved win a plastic vehicle-interior-part with an impact module, whereas the impact module is made from an expanded, plastic foam material.
Preferably, the expanded foam material is an expanded polypropylene. The expanded plastic foam material can he at least partially covered with a coating, preferably a plastic coating, particularly to improve the grade of the surface of the impact module.
Preferably, the impact module has a 3D-shape, whereas particularly the thickness of the impact module varies. Preferably, the shape of the impact module is adapted to the plastic vehicle-part to which it is attached. Preferably, the thickness of the impact module is reduced in its attachment region. Preferably, the impact module comprises a slot, more preferably a T-shaped slot, to attach the impact module to the plastic vehicle-part.
The impact module can be attached to the plastic part by any means known to a person skilled in the art. The impact module can be for example glued to the plastic vehicle-part. The impact module can he molded together with the plastic vehicle-part. However, preferably, the impact module is attached to the. plastic vehicle-interior-part by means of a form- and/or force-fitting-means. Preferably, there are two or more means to attach the impact module to the plastic vehicle-part. Preferably, the impact module is attached to the plastic vehicle-part-with one or more plastic barb(s).
The invention is explained in further detail according to
a-2d show the impact module 1 in different views. As can be seen, the impact module as shaped three dimensionally and has slots 1.1 which allow a form- and/or force-fit between the impact module 1 and the side valance 2. The slot is, in the present case T-shaped, so that the form- and/or force-fitting-means 2.1 can he introduced into the slot at the top of the T and are then drawn or pushed downwards. The impact module is in the present case made from expanded polypropylene. The impact module may, at least partially, comprise a coating of its surface. In the area 1.1, where the impact module 1 is attached to the plastic vehicle-part, it preferably comprises a reduced thickness.
a and 4b show the attachment of the impact module 1 to the side valance 2. The side valance 2 comprises form- and/or force-fitting-means here plastic barbs 2.1, which are inserted into the slots 1.1 of the impact module 1. Due to these barbs, a form- and/or a force-fit between the impact module 1 and the side valance 2 is realized. The form- and/or force-fitting-means 2.1 can be attached to the side valance 2 or the side valance 2 and the form- and/or force-fitting-means 2.1 can be provided as one piece, for example produced during one molding process.
