Abstract

The impact-element of this invention includes an energy-absorbing, elongated deformation member which is secured to an elongated, dimensionally stable carrier that is, in turn, mounted below the dashboard of the vehicle. The energy-absorbing deformation forces are generally independent of the impact direction. In one embodiment of the invention, the energy-absorbing deformation member is an elongated, hollow body which, in transverse cross section, is ring-shaped at least in the portion opposing the knees of the occupants of the vehicle. In an alternative embodiment of the invention, the elongated, energy-absorbing member is hollow and is box-shaped in transverse cross section. In the second embodiment of the invention, a dimensionally stable, elongated cross piece is diagonally positioned within the box-shaped energy-absorbing member and contacts the upper end of the carrier. Stiffening means in the form of corrugations may be provided in both the box-shaped, energy-absorbing member and the cross piece of the second embodiment.

Claims

1. A safety device for protecting an occupant of a vehicle, particularly a motor vehicle, against injury in the event of rapid deceleration of the vehicle relative to the occupant, comprising

a rigid carrier;

means for mounting said carrier in the passenger compartment of a vehicle forwardly of the position assumed by an occupant; and

a plastically deformable energy-absorbing member provided on said carrier and positioned to undergo plastic deformation upon impacting by the occupant to thereby absorb the impact energy and protect the occupant, said member being constructed in the form of a hollow body which is box-shaped in cross section and wherein there is further provided a deformation resistant, diagonally oriented cross piece in said hollow body.

2. The device according to claim 1 wherein said diagonal cross piece contact an upper end of said carrier.

3. The device according to claim 1 wherein said diagonal cross piece includes stiffening corrugations extending in a transverse direction.

4. The device according to claim 1 wherein two surfaces of said box-shaped hollow energy-absorbing member each include at least one stiffening corrugation extending in a longitudinal direction.

5. The device according to claim 1 wherein said energy-absorbing deformation member is made of sheet metal.

6. The device according to claim 1 wherein said carrier is adapted to be removably connected to the vehicle.

7. The device according to claim 5, wherein said carrier is adapted to be removably secured to the front door post of the vehicle.

8. The device according to claim 1 wherein said energy-absorbing deformation member is of polygonal cross section.

9. The device according to claim 8, wherein said energy-absorbing deformation member includes an angularly oriented end face that is in opposition to said carrier.

10. The device according to claim 9, wherein said angularly oriented end face forms an acute angle with respect to one surface of said energy-absorbing deformation member and forms an obtuse angle with respect to an opposed other surface of said energy-absorbing deformation member.

11. The device according to claim 1, wherein said energy-absorbing member is adapted to be positioned below and in spaced relationship with the dashboard of the motor vehicle.
