Abstract
An armature for a motor-vehicle steering wheel. The hub, spokes, and rim are at least partly made out of a single sheet of metal. The metal is folded at the edge to produce a cross-section in the form of a U or L. The base of the section is essentially perpendicular to the axis of the steering wheel. The sides of the section essentially parallel that axis. The sides of the U or L are provided with an undulation as viewed longitudinally, that is almost non-existent in the vicinity of the base, and that increases continuously to a maximum as it approaches the edge.

An armature for a motor-vehicle steering wheel, wherein a hub, spokes, and rim are at least partly made out of a single sheet of metal, wherein the metal is folded upwardly at an edge to produce a cross-section in the form of one of U and L, a base of the cross-section essentially perpendicular to an axis of a steering wheel in use and sides of the cross-section and essentially parallel said steering wheel axis and facing a driver during use, wherein the sides of the U or L are provided with undulation as viewed longitudinally, that is substantially zero in the vicinity of the base, and that increases continuously to a maximum as said undulation approaches the edge.
