Abstract

An assembly for a motor vehicle includes an instrument panel and a restraining device which is configured to limit a relative movement between at least a panel section of the instrument panel and a vehicle component of the motor vehicle to a predefined maximum value in a movement direction towards an interior space of a passenger cell of the motor vehicle, when a force is transmitted between the instrument panel and the vehicle component as a result of an accident that causes deformation of the instrument panel.

First claim

What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims and includes equivalents of the elements recited therein:

1. An assembly for a motor vehicle, said assembly comprising:
an instrument panel; and
a restraining device configured to limit a relative movement between at least a panel section of the instrument panel and a vehicle component of the motor vehicle to a predefined maximum value in a movement direction towards an interior space of a passenger cell of the motor vehicle, when a force is transmitted between the instrument panel and the vehicle component as a result of an accident that causes deformation of the instrument panel,
wherein the restraining device includes a malleable deformation component which undergoes deformation when the instrument panel deforms as a result of the accident and the relative movement is limited,
wherein the deformation component includes a fabric extending between opposing ends of the deformation component to limit the relative movement.

2. The assembly of claim 1 , further comprising a dashboard support configured to mount the instrument panel to the motor vehicle, said restraining device being coupled to the dashboard support for force transmission.

3. The assembly of claim 1 , further comprising an airbag device secured to the instrument panel and including a chute channel element, said restraining device being coupled to the chute channel element for force transmission.

4. The assembly of claim 1 , wherein the deformation component includes a spring element to limit the relative movement.

5. The assembly of claim 1 , wherein the deformation component includes a damper element to limit the relative movement.

6. The assembly of claim 1 , wherein the deformation component includes an undulated region when in a state absent any deformation thereof.

7. A motor vehicle, comprising:
a passenger cell;
a vehicle component; and
an assembly comprising an instrument panel, and a restraining device configured to limit a relative movement between at least a panel section of the instrument panel and the vehicle component of the motor vehicle to a predefined maximum value in a movement direction towards an interior space of the passenger cell of the motor vehicle, when a force is transmitted between the instrument panel and the vehicle component as a result of an accident that causes deformation of the instrument panel,
wherein the restraining device includes a malleable deformation component which undergoes deformation when the instrument panel deforms as a result of the accident and the relative movement is limited,
wherein the deformation component includes a fabric extending between opposing ends of the deformation component to limit the relative movement.

8. The motor vehicle of claim 7 , wherein the assembly includes a dashboard support configured to mount the instrument panel to the motor vehicle, said restraining device being coupled to the dashboard support for force transmission.

9. The motor vehicle of claim 7 , wherein the assembly includes an airbag device secured to the instrument panel and including a chute channel element, said restraining device being coupled to the chute channel element for force transmission.

10. The motor vehicle of claim 7 , wherein the deformation component includes a spring element to limit the relative movement.

11. The motor vehicle of claim 7 , wherein the deformation component includes a damper element to limit the relative movement.

12. The motor vehicle of claim 7 , wherein the deformation component includes an undulated region when in a state absent any deformation thereof.

13. The motor vehicle of claim 7 , wherein the vehicle component is embodied as a cross member or a side rail of the motor vehicle.
