<p>A steering shaft (21) has a steering wheel (20) connected to its upper end, and a steering gear (27) connected to its lower end. The steering shaft consists of an elongate energy absorbing tube (23,25) having a bond (24) between the tube and one or both the steering wheel and the steering gear. The longitudinal axial component of the bond is adapted to disrupt under crash impact and to allow the tube to progressively collapse and absorb the impact energy.</p> |
