## 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.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 1)

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.

### Claim 4 (depends on 1)

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

### Claim 5 (depends on 1)

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

### Claim 6 (depends on 1)

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

### Claim 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.

### Claim 8 (depends on 7)

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.

### Claim 9 (depends on 7)

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.

### Claim 10 (depends on 7)

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

### Claim 11 (depends on 7)

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

### Claim 12 (depends on 7)

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

### Claim 13 (depends on 7)

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