ABSTRACT:
A clamping mechanism for an adjustable steering column includes clamping members which are drawn by a spring against sides of a steering column mounting bracket which flexes to clamp a steering column supporting adjustment bracket. The clamping members are located at opposite pivot points of a parallelogram linkage which has intermediate pivot points coupled to a Bowden cable with sheath. Operating the Bowden cable to draw arms of the linkage together against the bias of the spring causes the clamping members to be unclamped to allow adjustment of the steering column.
