Mecanismo de aperto de coluna de direção

摘要

A steering column clamping mechanism has bolt links interconnecting substantially parallel spaced-apart plates which basically form a rectangle and are so linked one to another that the rectangle can assume an orientation defining a non-rectangular parallelogram or lozenge. One of the connecting bolts is mounted in a bracket fixed to a chassis of a vehicle, the bracket having a depending reaction plate against which an actuating member can be urged to push the plate member away from the reaction member. Through the linkage, this causes the other plate member to compress onto a steering column tube member to clamp it between that plate and the opposite side of the reaction plate.
