Abstract

The sill panel is of multi-part design and consists of a lower sill panel part facing the carriageway and composed of nonwoven fabric (LWRT) and of an upper adjoining sill panel part composed of plastic (PTT). The two sill panel parts are connected to each other by means of an edge-side overlap which is adhesively bonded or welded.

First claim

What is claimed is:

1. A side sill for a motor vehicle, with an outer sill panel of profiled cross section, the outer sill panel being of multi-part design and comprising: a lower first sill panel part that faces a roadway and is composed of a light weight reinforced thermoplastic (LWRT) that is acoustically active for reducing stone impact noise, the first sill panel part being connected to an upper second sill panel part composed of plastic (PTT), the first sill panel part being joined to the second sill panel part at a flat overlap formed by a planar extension of the second sill panel part and an offset planar extension of the first sill panel part, the offset planar extension of the first sill panel part being secured in face-to-face contact with an inwardly facing surface of the planar extension of the second sill panel part and so that an outer surface of the planar extension of the second sill panel part is flush with an outer surface of the first sill panel part adjacent the offset planar extension of the first sill panel part.

2. The side sill of claim 1 , wherein the connection of the planar extensions of the first and second panel parts takes place via a retrospective welding or adhesive bonding.

3. The side sill of claim 1 the first sill panel part comprises nonwoven fabric.

4. The side sill of claim 1 , wherein the second sill panel part has a plurality of transversely running sprues for the first sill panel part.

5. The side sill of claim 1 , wherein the first panel part or the second panel part is insert molded on the second panel part or on the first panel part.
