Abstract

An energy-absorbing covering for a body column of a motor vehicle includes on an area situated in the occupant compartment a covering part and an energy-absorbing element, which is arranged between the body column and the covering part. The energy-absorbing element is formed by a hollow-space-bounding support made of sheet metal. So that a lateral bending-away of the energy-absorbing element is avoided even if the energy-absorbing element is acted upon in an unfavorable direction, while the energy-absorbing covering has a construction which is easy to mount, and, in addition, rattling noises in the driving operation are avoided, it is provided that the energy-absorbing element is connected on the side facing the body column at least in areas with a profiled holding rail which, in sections, rests on the body column and is locally fixedly connected with it. The covering part, which is arranged at a distance in front of the energy-absorbing element, is fastened locally to the holding rail or to the body column.

Claims

1. An energy-absorbing covering for a body column of a motor vehicle, said covering being provided on an area of the body column situated in an occupant compartment of the motor vehicle, comprising:

a covering part;

an energy-absorbing element arranged between the covering part and an inner panel of the body column, the energy-absorbing element having a hollow interior space and being made of sheet metal; and

a profiled holding rail, said energy absorbing element being supported at opposite ends on a side facing the body column over at least a part of its length by said profiled holding rail;

wherein said profiled holding rail abuts areas of the inner panel form-lockingly along a substantial width of the holding rail and is locally fixedly connected with the inner panel of the body column.

2. Energy-absorbing covering according to claim 1, wherein the energy-absorbing element and the holding rail form a prefabricated constructional unit.

3. Energy-absorbing covering according to claim 1, wherein in a cross-sectional view, the energy-absorbing element has an approximately U-shaped profile having two legs, free ends of the two legs respectively being locally connected with respective interior flanges of the holding rail, each associated free end and interior flange extending in the same direction.

4. Energy-absorbing covering according to claim 2, wherein in a cross-sectional view, the energy-absorbing element has an approximately U-shaped profile having two legs, free ends of the two legs respectively being locally connected with respective interior flanges of the holding rail, each associated free end and interior flange extending in the same direction.

5. Energy-absorbing covering according to claim 3, wherein the energy-absorbing element is connected at a locally defined area with the holding rail by one of welding, soldering, gluing, forming and the like.

6. Energy-absorbing covering according to claim 1, wherein the holding rail and the energy-absorbing element are fastened to the body column by one of riveted, welded and screwed connections.

7. Energy-absorbing covering according to claim 1, wherein the holding rail is made of one of sheet aluminum and steel plate and the energy-absorbing element is made of one of sheet aluminum and steel plate, a thickness of the metal sheets amounting to approximately between 0.5 and 2.0 mm.

8. Energy-absorbing covering according to claim 1, wherein the holding rail projects beyond the energy-absorbing element in a downward direction by a defined extent.

9. Energy-absorbing covering according to claim 1, wherein the energy-absorbing element projects behind the holding rail in an upward direction by a defined extent.

10. Energy-absorbing covering according to claim 1, wherein the covering part, which is arranged at a distance in front of the energy-absorbing element, is fastened to the holding rail at a locally defined area.

11. Energy-absorbing covering according to claim 1, wherein the covering part, which is arranged at a distance in front of the energy-absorbing element, is fastened to the body column at a locally defined area.

12. Energy-absorbing covering according to claim 1, wherein at least one oblong slot opening is constructed on the energy-absorbing element, said slot allowing the holding rail to be fastened to the body column and the covering part to be fastened to one of the holding rail and the body column.

13. Energy-absorbing covering according to claim 1, wherein one support flange respectively having an oblong hole is constructed on both elongated ends of the holding rail, into which oblong hole an elastic holding clamp is inserted, a free end of a fastening web of the covering part being insertable into each holding clamp.

14. Energy-absorbing covering according to claim 13, wherein an upper support flange of the holding rail projects through the oblong slot opening of the energy-absorbing element.

15. Energy-absorbing covering according to claim 1, wherein fastening webs of the covering part are aligned approximately perpendicularly to a bent support flange of the holding rail.

16. Energy-absorbing covering according to claim 1, wherein a fastening web of the covering part projecting through an oblong slot opening of the energy-absorbing element can be fitted into a holding clamp, the holding clamp being inserted into an oblong hole of an inside panel of the body column, the holding clamp having a holding tongue with a narrowed section, behind which narrowed section a projecting holding nose of the fastening web reaches when the covering part is mounted.

17. Energy-absorbing covering according to claim 13, wherein each fastening web has on its free end a locally projecting holding nose, and wherein each holding clamp includes a holding tongue having a narrowed section, said projecting holding nose reaching behind the respective holding tongue.

18. Energy-absorbing covering according to claim 1, wherein intermediate felt layers for avoiding rattling noises are placed between the covering part and the energy-absorbing element.
