Abstract
A rod with an increased capacity for buckling under length-wise load has a central portion bent in the form of an omega with a central bend joined to end portions by elbows. The cross-section of the central portion is formed, for example by plastic deformation, into the shape of a bow-tie or the mathematical symbol 'infinity' which consists of two lateral lobes connected by a thin central core and which is inscribed in a rectangle of which the length is equal to at least twice its width. Such rod is used as a shaft in a motor vehicle safety steering column.
