Head support for vehicle seat; has support rod guided in longitudinal guide device with rotatable guide sleeve in back rest, where head support is pivoted forwards as it is raised.

摘要

The support is fixed to a back rest by at least one support rod (2,2'), which is guided in a longitudinal guide device and can pivot about a horizontal axis (6,6'). The head support can be pivoted forwards by a forced control according to increasing height. The guide device has a guide sleeve (4,4') that is rotatably supported about its longitudinal central axis. The guide sleeve engages the support rod over its entire height-adjustment area and has an inner spiral groove (4a,4a') extending over the height-adjustment area to engage a pin (2a') fixed to the support rod. The guide sleeve rotates as the head support is adjusted, and supports a support area (3,3') fixed to the support structure by a transverse guide area fixed to the guide sleeve and running radially and eccentrically to its longitudinal central axis.
