Abstract

A guide device for a retaining rod of a headrest, having a guide structure forming a channel for guiding and supporting the retaining rod, having a latch device including a latch movable between a latching position and a release position. The latch cooperates with a latch structure of the retaining rod to prevent movement of the retaining rod relative to the guide structure in at least one direction. In the latching position the latch device is engaged with the latch structure of the retaining rod and in the release position the latch is disengaged from the latch structure. The latch device has a locking device movable between a locking position and a disengagement position and has a locking structure which, in the locking position, is in the movement path of the latch to prevent movement from the latching position into the release position and, in a disengagement position, enable movement of the latch into a release position.
