Operating device for fixing bar of headrest of motor vehicle, has bearing sleeve and pivot movement released during operation of drive slide gate valve is transferred on head as rotating movement

摘要

The operating device has a bearing sleeve (2), and a slide gate valve in the bearing sleeve in an operation direction, and a mechanism influencing on fixing bar. The mechanism has a articulation arm (5) applied rotating to the bearing sleeve, which can be rotated with the slide gate valve over an angular region, and directed to connect articulation head (6) with the fixing bar in a torque proof manner. The articulation head is so coupled with the arm that the pivot movement released during operation of the drive slide gate valve is transferred on the articulation head as rotating movement.
