ABSTRACT:
A coupling member for taking up torque in a vehicle steering column to absorb vibration and vehicle body misalignment, the coupling member including a plastics disc with a pair of diametrically opposed bosses which protrude further from one face of the disc than from the other face, and another pair of diametrically opposed bosses which protrude further from the other face of the disc than from its one face.
The disc is able to distort upon application of torque through the bosses by means of a cut-out portion between each adjacent boss. A fail-safe deflection plate can be provided on each face of the disc to react against opposed pairs of bosses in the event of high application of torque. An adaptor piece holding one end of a steering column is fitted to one face of the disc and a splined flange is secured to the other face of the disc to enable the coupling member to be secured to another steering column component.
