Clamping mechanism for an adjustable steering column

摘要

Clamping members (6) are drawn by a spring (9) against sides of a steering column mounting bracket (4) which flexes to clamp a steering column supporting adjustment bracket (3). The clamping members (6) are located at opposite pivot points of a parallelogram linkage (5) which has intermediate pivot points coupled to a Bowden cable (11) with sheath (10). Operating the Bowden cable to draw arms (7) of the linkage together against the bias of the spring (9) causes the clamping members (6) to be unclamped to allow adjustment of the steering column.
