Abstract

A spare wheel lift mechanism is provided for a motor vehicle. That spare wheel lift mechanism includes a holder for receiving and holding the spare wheel and a support for the holder. The support is displaceable between a wheel storage position within a storage compartment of the motor vehicle and an access position wherein the spare wheel projects at least partially outside the body of the motor vehicle for easy access. A method of assisting an individual with access to a spare wheel stored in a storage compartment of a motor vehicle is also provided.

First claim

What is claimed:

1. A spare wheel lift mechanism for a motor vehicle, comprising:
a holder for receiving and holding a spare wheel;
a support for said holder, said spare wheel lift mechanism being displaceable between a wheel storage position within a storage compartment of said motor vehicle and an access position wherein said spare wheel projects at least partially outside a body of said motor vehicle; and
a counter balancing element for biasing said support toward said access position, said counter balancing element being formed by a torsion bar.

2. The spare wheel lift mechanism of claim 1 , wherein said support includes a linkage having a first end connected to said motor vehicle and a second end connected to said holder.

3. The spare wheel lift mechanism of claim 2 , wherein said support further includes a base fixed to said motor vehicle and a bracket fixed to said holder.

4. The spare wheel lift mechanism of claim 3 , wherein said support further includes a first hinge connecting said first end of said linkage to said base and a second hinge connecting said second end of said linkage to said bracket.

5. The spare wheel lift mechanism of claim 4 , wherein said linkage includes a first link and a second link.

6. The spare wheel lift mechanism of claim 5 , wherein said first hinge is a dual hinge connecting said first link and said second link to said base.

7. The spare wheel lift mechanism of claim 6 , wherein said second hinge is a dual hinge connecting said first link and said second link to said bracket.

8. The spare wheel lift mechanism of claim 7 , wherein said torsion bar includes a first section forming a first hinge pin for said first hinge.

9. The spare wheel lift mechanism of claim 8 , wherein said torsion bar includes a second section forming a second hinge pin for said first hinge.

10. The spare wheel lift mechanism of claim 9 , wherein said linkage includes a flange and said torsion bar includes a third section that engages said flange.

11. The spare wheel lift mechanism of claim 10 , wherein said base includes two opposed flanges having a first set of opposed apertures and a second set of opposed apertures.

12. The spare wheel lift mechanism of claim 11 , wherein said first section of said torsion bar extends through said first set of opposed apertures and said second section of said torsion bar extends through said second set of opposed apertures.

13. The spare wheel lift mechanism of claim 1 , further including a counter balancing element connecting said support to said holder and biasing said support toward said access position.

14. A motor vehicle incorporating the spare wheel assist mechanism set forth in claim 1 .

15. A method of assisting an individual with access to a spare wheel stored in a storage compartment of a motor vehicle, comprising:
holding said spare wheel on a support that his displaceable between a storage position within said storage compartment and a raised, access position; and
biasing, by a torsion bar, said support toward said access position so as to reduce effort of said individual required to raise said support and said spare wheel.

16. The method of claim 15 , including holding said spare wheel so that said spare wheel at least partially projects from a body of the motor vehicle when in said access position.
