Description

The invention relates to a covering device for an airbag module arranged in a receiving area of an instrument panel of a motor vehicle according to claim 1. Furthermore, the invention relates to an arrangement of an airbag module in a receiving area of an instrument panel for a motor vehicle according to claim 8. The DE 10 2020 110 967 A1 Disclosing an airbag module for a motor vehicle, comprising a housing located in the receiving space, which terminates at an end face of the housing extending in a plane, is supported via the end face on at least one further component of the motor vehicle and has an opening around which the end face extends at least partially in the circumferential direction of the opening, and comprising at least one airbag located in a stowed position, which has at least one airbag part arranged in the receiving space which, for moving the airbag from the stowed position into a restraint position, is at least partially movable out of the receiving space via the opening, wherein at least one cover element is provided which at least partially covers the airbag on a side of the airbag facing away from the housing and which is tensioned against the housing by means of at least one tensioning element. The object of the invention is to provide a covering device for an airbag module arranged in a receiving area of an instrument panel of a motor vehicle, as well as an arrangement of an airbag module in a receiving area of an instrument panel for a motor vehicle, so that the safety of the motor vehicle can be particularly improved. This problem is solved according to the invention by a covering device for an airbag module arranged in a receiving area of an instrument panel of a motor vehicle, comprising the features of claim 1, and by an arrangement of an airbag module in a receiving area of an instrument panel of a motor vehicle, comprising the features of claim 8. Advantageous embodiments of the invention are the subject of the dependent claims and the description. A first aspect of the invention relates to a covering device for an airbag module arranged or to be arranged in a receiving area of an instrument panel of a motor vehicle. This can be understood to mean, in particular, that the covering device is provided or designed to cover the airbag module, especially an airbag of the airbag module. The motor vehicle is, for example, a passenger car or a commercial vehicle. Preferably, the motor vehicle, particularly in its fully manufactured state, has the covering device and/or the airbag module. The term "airbag module" can thus be understood to refer in particular to an airbag module of the motor vehicle. The cover device comprises at least one cover element which is pivotable about at least one pivot axis, for example at least indirectly or directly, on at least one wall of the instrument panel that at least partially, in particular predominantly or completely, defines the receiving area, via a mounting area between a closed position and at least one open position, which is, in particular, different from the closed position. In other words, the cover element is pivotable about the pivot axis from the closed position to the open position, in particular relative to the wall, and/or from the open position to the closed position, in particular relative to the wall, wherein the cover element can be attached or is attached to the wall of the instrument panel at least indirectly, in particular directly, via the mounting area, or can be connected or is connected to the wall. The cover element, in particular the cover device, can be referred to as an airbag flap or airbag cover, or simply as a cover. In particular, the cover device, for example the cover element, comprises the mounting area. The term "wall" can refer in particular to a wall element of the instrument panel. The term "instrument panel," which can also be called an I-panel, can refer in particular to a dashboard. Preferably, the instrument panel is located in a forward area of the interior, relative to the longitudinal direction of the vehicle. The term "interior," which can also be called the vehicle interior, can refer in particular to a passenger compartment or passenger cell. The requirement that the recording area is at least partially bounded by the wall of the instrument panel can be understood, in particular, to mean that the recording area is at least partially formed by the wall. In other words, the recording area is at least partially, and especially predominantly or completely, for example, entirely, surrounded or covered by the wall. The airbag module, for example, The housing of the airbag module is preferably designed to correspond to the receiving area. Preferably, the airbag module, and in particular its housing, is arranged or positioned at least predominantly, and especially completely, within the receiving area of the instrument panel. The cover element has at least one outer surface facing upwards in the vehicle's v
