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.

Abstract: A guide device for a headrest with a guide structure for supporting and guiding an end region of a holding rod and with a trim part for covering an edge region of an opening for the passage of the holding rod in a cushion, wherein the holding rod can be releasably locked by a latch device in at least one position relative to the guide structure. The guide device includes the trim part and the guide structure, wherein the trim part has first fastening components which are engageable with second fastening components of the guide structure.

Abstract: Inter alia, the invention relates to a support bracket (12) with two bar regions bracket on a vehicle seat, with a traverse (15) connecting the bar regions pivotally supporting a head contact part (11) of a headrest (10), and with locking means of a latch (17) for blocking pivoting the head contact part (11). The special feature is that the traverse (15) is made of plastic or a composite material and comprises attachment regions for securing to a support rod (13a, 13b) or is integrally connected with bar regions.

Abstract: A headrest (10) for a vehicle seat has at least one base (11), such as a support rod or the like. A main body (12) is held on the base (11). A support part (13) having a head support surface (44) can move relative to the main body (12) forward in the forward direction (x) toward the back of the head of the vehicle occupant and back in the rearward direction (z). The main body (12) is movable on the base (11) and can be shifted by at least one rotatable transmission element (K1; 28, 30) in the forward direction (x) and in the rearward direction (z). At the same time, the support part, which moveable in the same direction with the main body (12) in the forward direction (x) and the rearward direction (z), is pivoted on the same rotatable transmission element (K1; 28, 30).

Abstract: A headrest has a generally stationary support, a headrest body having a forwardly directed front face and positioned such that a head of a user seated in front of the support is generally level with the body, and a guide securing the body to the support for vertical movement relative to the support. A drive can vertically shift the body relative to the support. A sensor assembly has at least three horizontally elongated and vertically spaced electrodes carried on the front face. A controller connected to the electrodes and to the drive means detects a vertical position of the user's head relative to the body and displaces the body so as to centrally align with the user's head.
