Abstract

Claims (22)

1. A bolster assembly for a vehicle comprising:

a body;

a plurality of brackets provided on a front surface of said body, said brackets being arranged in paired sets; and

a plurality of energy absorbing elements, wherein each energy absorbing element is operably associated with a respective bracket, and where within each paired set of brackets, said energy absorbing elements are disposed in adjacent relationship separated by a gap,

wherein said paired sets of brackets are aligned with a frame structure provided in said vehicle, said frame structure having a width greater than said gap, and

wherein upon a crash event and forward displacement of said body, said paired sets of brackets engage said frame structure, said energy absorbing elements deforming during said forward displacement to absorb energy.

2. The bolster assembly of claim 1 , wherein said body is injection molded, and said brackets are integrally formed with said body.

3. The bolster assembly of claim 2 , wherein said body and said brackets are provided with incorporated gas cells in the injection molded structure, thereby defining a foamed core.

4. The bolster assembly of claim 1 , wherein said body further comprises one or more integrally formed stiffening ribs.

5. The bolster assembly of claim 1 , wherein said energy absorbing elements are provided with a lead-in region that is angularly deflected, serving to establish a pre-determined direction of deformation on engagement with said frame structure.

6. The bolster assembly of claim 1 , wherein said front surface of said body additionally comprises suitable fasteners for mounting said bolster assembly to an instrument panel.

7. The bolster assembly of claim 6 , wherein said fastener generally comprises a fastening clip mounted on a clip tower, the clip/tower arrangement cooperating with a mating aperture on said instrument panel.

8. The bolster assembly of claim 1 , wherein said energy absorbing element is a separately formed component, and is in-molded during production, or inserted post-production into said bracket.

9. The bolster assembly of claim 1 , wherein said energy absorbing element is provided with anchorage features to ensure retention of said energy absorbing element in said bracket.

10. The bolster assembly of claim 1 , wherein two opposing energy absorbing elements provided in a paired set of brackets is provided generally in U-shaped form.

11. A bolster system for a vehicle comprising:

a frame structure provided on said vehicle, said frame structure comprising a cross-bar beam and one or more extension beams extending therefrom; and

a bolster assembly for mounting to said vehicle, said bolster assembly comprising a body;

a plurality of brackets provided on a front surface of said body, said brackets being arranged in paired sets; and

a plurality of energy absorbing elements, wherein each energy absorbing element is operably associated with a respective bracket, and where within each paired set of brackets, said energy absorbing elements are disposed in adjacent relationship separated by a gap,

wherein said paired sets of brackets are aligned with a respective extension beam, said extension beam having a width greater than said gap, and

wherein upon a crash event and forward displacement of said body, said paired sets of brackets engage said extension beam, said energy absorbing elements deforming during said forward displacement to absorb energy.
