Instrument panel with a passenger airbag
View Patent ↗An instrument panel has a passenger airbag system such that, in the deployment of the airbag, an airbag cover on the top side of the instrument panel adjacent to the windshield is upwardly displaceable in the direction of the windshield about a transverse pivot axis. Thereby, a passage for the actual airbag of the passenger airbag module is cleared. In order to prevent damage to the windshield due to the airbag cover being pivoted upward when the airbag is deployed, a transverse intended breaking line is provided on the airbag cover at a distance from the pivot axis so that the airbag cover is bent upward about this intended breaking line when it comes to rest against the windshield.
1. Instrument panel accommodating a front passenger airbag, comprising an airbag covering extending on a top side of and being integrated with the instrument panel adjacent to a windshield, the instrument panel being displaceable in an upward direction toward the windshield about a transversely extending swiveling axis to open up a passage opening for a gas bag of the front passenger airbag, a transversely extending desired buckling point is spaced from the swiveling axis on the airbag covering constructed integrally with the instrument panel such that the airbag covering is able to fold upwards about the buckling point when resting against the windshield, the airbag covering being connected on an interior side thereof with a thin-walled sheet metal part, a bent forward edge area of the sheet metal part being operatively fastenable to an adjoining shooting channel of the front passenger airbag, and the desired buckling point being constituted by an outwardly-directed or upwardly-directed bead of the sheet metal part and a corresponding weakening of the adjoining rigid carrier part of the instrument panel or of the airbag covering.
2. Instrument panel according to claim 1 , wherein
the instrument panel and the airbag covering are comprised of the rigid carrier part, a plastic foam layer disposed above the rigid carrier part and a decorative layer provided on a side of the front passenger space.
3. Instrument panel according to claim 1 , wherein a radius-shaped transition area of the sheet metal part forms the transversely extending swiveling axis for the airbag covering.
4. Instrument panel according claim 1 , wherein the sheet metal part extends over substantially an entire surface area of the airbag covering.
5. Instrument panel according to claim 1 , wherein an edge side of the sheet metal part has a surrounding, frame-shaped, inward-directed stiffening crease.
6. Instrument panel according to claim 5 , wherein the transversely extending buckling point projects approximately to both lateral edges of the surrounding stiffening bead.
7. Instrument panel according to claim 1 , wherein rivets locally connect the sheet metal part with the rigid carrier part.
