Problems solved by technology

Known elastic hinge solutions have the disadvantage that elongation of the flexible hinge material by creasing or bulging makes precise and reliably predictable elongation difficult, so that the hinge effect often cannot be designed with sufficient reproducibility

Embodiment Construction

[0040] exist Figure 1a , 1b , and 1c, a schematic diagram showing the principle of hinge fastening of an airbag door flap according to the prior art.

[0041] Figure 1a An airbag door flap 1 is shown, which is integrated into an interior trim component 4 of a motor vehicle. The airbag door flap 1 is connected on the bottom side to a strap hinge 3 which extends across the swivel point 6 to the trim part 4 and is firmly connected thereto.

[0042] Figure 1b The airbag door flap 1 is shown after airbag deployment (not depicted). The airbag door flap 1 rotates about the pivot point 6 of the strap hinge 3 and is held by the strap hinge 3 . The hinge region 2 of the flexible strap hinge 3 enables the rotation of the airbag door flap 1 .

[0043] According to the existing technology, such as Figure 1c As shown in , the extra length of the strap hinge 3 is held ready for use in the hinge region 2 by the length supply in folded form, for example, to wrap the airbag door flap 1...

Abstract

The invention relates to an interior trim component with an airbag door flap for a motor vehicle with an airbag system, wherein the airbag door flap (1) is held in the open state by means of an elastic belt hinge (3). A hinge area (2) is rotatably attached to said trim panel part (4), characterized in that ribs (8, 9, 10) are provided in said hinge area (2), said ribs delimiting said Changed length (X) of strap hinge (3).

Description

technical field [0001] The invention relates to an interior trim component with an airbag door flap for a motor vehicle with an airbag system. Background technique [0002] The airbag door flaps in modern airbag systems are integrated into the trim panel and connected to the trim panel components by means of hinge solutions. As a result, airbag door flaps can be successfully opened after deployment of the airbag, while the flaps are held by hinges and cannot be thrown into the passenger compartment, where they could become uncontrolled and damage the occupants of the vehicle. [0003] A number of different technologies for airbag door flaps and reinforcements for the hinge area are known in the prior art. For example, an airbag door flap is implemented as a metal plate attached to a carrier part / base plate. Alternatively, the airbag door flap is made of a soft material that is welded by injection molding the carrier part / base plate or welded, sprayed on fabric or sprayed o...
