Cover plate for an airbag module
View Patent ↗A cover plate for an airbag module, such as a driver side airbag module. The cover plate includes a cover part and at least one wall which extends in a generally perpendicular manner in relation to the cover part. In order to prevent indentation areas from forming on the visible surface of the cover part on the transition points towards the walls and to provide the simple deformation of the airbag cover from the production tool, the wall extends, when seen in the cross-section thereof, at distances which are short in relation to the length of the wall, alternating in different directions.
1. A cover plate for an airbag module, comprising:
a cover part;
and at least one wall which extends away from the cover part in a direction essentially perpendicular to the cover part,
wherein the wall, when viewed in a cross section made by sectioning the wall along a plane essentially parallel to the cover part, runs in different directions in an alternating manner at distances which are short in relation to the length of the wall so that the wall runs in a circuitous manner,
wherein openings are provided for latching a generator support to the cover plate at wall sections which bear against wall regions of the generator support which are provided with fastening elements, and
wherein the cross section of the wall changes in direction at the edges of the openings.
2. The cover plate as claimed in claim 1 , wherein the thickness of the wall is half to a third of the thickness of the cover part.
3. The cover plate as claimed in claim 1 , wherein the wall has reinforcing ribs.
4. The cover plate as claimed in claim 3 , wherein the reinforcing ribs run away generally perpendicular from a cover plate without being connected to the cover plate.
5. The cover plate as claimed in claim 1 , wherein four inter-connected walls are provided, of which three run in different directions in an alternating manner in cross section.
6. The cover plate as claimed in claim 5 , wherein two side walls and a rear wall run in different directions in an alternating manner in cross section.
7. The cover plate as claimed in claim 5 , wherein at least one wall is at least partially slit generally perpendicular with respect to the cover part.
8. The cover plate as claimed in claim 1 , wherein both sides of the wall run in parallel.
