Car seat for railed adjusting movement

摘要

A clamp on rail (2,102) can only move at right angles to the rail but is pressed to the other rail (7,107) at pre-set force, using an actuator (14,114) to modify the contact force of the clamp (111). Thus the clamp designed as a friction element can be raised off the second rail by the actuator and is forced onto the rail by a spring (113). The actuator is controlled by the backrest (6) or backrest lock. It uses the clamp as a bow to clasp the rail (2) from above. It clasps the bottom rail from below to include the load spring between yoke part and top rail.
