Embodiment Construction

[0023] The cover plate 1 shown in FIGS. 1 and 2 has a cover part 2 , a front wall 3 and a rear wall 4 . The two walls are connected to each other by side walls 5 , 6 . Where the walls 3, 4 are substantially rectilinear in cross-section, the side walls 5, 6 extend in a slightly curved manner and bend inwards at the front and rear. However, this profile offers hardly any improvement over a rectilinear profile in terms of the strength of the side walls 5,6.

[0024] Openings are provided in the side walls 5 , 6 , one of which 7 is shown in FIGS. 3 and 4 . Locking hooks 8 engage in said openings in order to lock the generator bracket (not shown) to the cover plate 1 .

[0025] 5 and 6 show the cover plate 9 of the present invention. The cover plate has a cover part 10 , a front wall 11 and a rear wall 12 . The two walls are connected to each other by side walls 13 , 14 . The rear wall 12 and the two side walls 13 , 14 have a meandering cross section. Such a cross-section inc...

Abstract

The invention relates to a cover for an airbag module, in particular a driver's airbag module. The cover plate includes a cover portion and at least one wall extending substantially perpendicularly relative to the cover portion. According to the invention, in order to prevent the formation of recessed areas on the visible surface at the transition point of the cover part to the wall and to ensure an easy deformation of the airbag cover from the production tool, the walls (12, 13, 14 when viewed in cross-section of the wall ) extend alternately in different directions for a distance shorter than the length of the wall.

Description

technical field [0001] The invention relates to a cover for an airbag module according to the preamble of claim 1 . Background technique [0002] A cover panel for an airbag module, in particular for a driver's airbag module, usually has a cover part, ie a cover panel in the narrower sense, and a plurality of interconnected walls connected to the cover part. The walls provided are generally front and rear walls and two side walls interconnecting the aforementioned walls. The wall is straight or slightly curved in cross-section. [0003] In known cover plates, the cover part and the wall have approximately the same wall thickness. Since they are manufactured as a single part, for example by injection moulding, this manufacturing method leads to the formation of sink marks on the visible surface of the cover part at the transition point from the cover part to the wall. [0004] Sink marks can be avoided if the ratio of the wall thickness to the thickness of the cover part i...
