Transmission shaft between seat backrest hinges - contains elastic clamp acting in axial direction

摘要

The transmission shaft is mounted between the hinges on opposite sides between a seat and backrest, particularly in a motor vehicle. An adjusting and locking mechanism acts between the halves of each hinge, one half is mounted on the eccentric portion of a rotary spindle with cone face and which is turned by a driving member. The two spindles are coupled by the transmission shaft. The transmission shaft (23) contains an elastic clamping device (33) exerting a force in the axial direction. ADVANTAGE - Exerts only axial force to hold spindle cone faces in engaged position.
