Abstract
A vehicle steering wheel comprises a steering wheel rim having a skeleton, whereon several predetermined deformation zones with predetermined deformation directions are defined. A rigid wood casing surrounds the skeleton. The wood casing has an inner side facing the skeleton, and a deformation space is provided in deformation direction between the inner side of the wood casing facing the skeleton and the skeleton in the predetermined deformation zones. The deformation space is greater than a space of the inner side of the wood casing to the skeleton in radial direction in other zones.
Claims11
A vehicle steering wheel comprising:
- a steering wheel rim (12) having a skeleton (24), several predetermined deformation zones (18) with predetermined deformation directions (Vx, Vy) being defined on said skeleton (24),
- and a rigid wood casing (20) surrounding said skeleton (24), said wood casing (20) having an inner side (26) facing said skeleton (24),
- a deformation space (dx, dy) being provided in said deformation direction (Vx, Vy) between said inner side (26) of said wood casing (20) facing said skeleton (24) and said skeleton (24) in said predetermined deformation zones (18),
- said deformation space (dx, dy) being greater than a space between said inner side (26) of said wood casing (20) and said skeleton (24) in radial direction (R) in other zones.
