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.

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.

Among other things, the invention relates to a mounting assembly for a headrest with at least one mounting rod (13a, 13b) having at least one retaining structure (17) that can be mounted on a vehicle seat by at least one mounting assembly (19a, 19b) having a respective seat (14), wherein the seat (14) forms a passage (25) for supporting and guiding the mounting rod (13a, 13b), wherein the mounting assembly (19a, 19b) has a latch assembly (15) that releasably latches the mounting rod (13a, 13b) can be releasably latched in at least one position relative to the seat (14), wherein the latch assembly (15) has at least one latch element (16) that is movable between a latching position and a release position and has a latch formation (21) that can be releasably engaged with at least one retaining structure (22) of the mounting rod (13a, 13b) to prevent movement of the mounting rod in at least one direction (p.sub.1, p.sub.2) along the passage (25).

The particularity is that the latch formation (21) has at least one mating surface (32, 33) that cooperates with a driving surface (34, 35) of the retaining structure (17) in such a way that when rotating the mounting rod (13a) about a longitudinal central axis (m) relative to at least one rotational direction (u.sub.1, u.sub.2), in particular relative to two opposite rotational directions (u.sub.1, u.sub.2), the latch element (16) is entrained.

There is shown and described, inter alia, a holder for supporting a headrest, which holder can be fixed in a retaining structure of a vehicle by insertion in a first mounting direction, wherein the holder is formed with a guide passage for receiving a retaining rod of the headrest, and wherein the holder has fixing means for fixing to a retaining structure of the vehicle.

The particular feature consists in that the fixing means have at least one deflection device, having at least one movable element that is supported on the holder so as to be movable from a first position in which the movable element is in the movement path of the retaining rod inserted into the guide passage, and a second position in which the movable element is outside the movement path, wherein the element has a region that is suitable for cooperating with an abutment surface of the retaining structure, in moving between the first position and the second position, such that the retaining element is loaded in a mounting direction relative to the retaining structure.

A quickly installed headrest adjustment device includes a mount case connected to the chair back and includes a recessed area, an engaging hole, a latch and a first contact face on the rear side of the chair back. The engaging hole is located between the two side slots and defined through the inner bottom of the recessed area. The latch is connected to the inner top side of the engaging hole and includes a bottom face which protrudes beyond the engaging hole and faces the inner side of the recessed area. An adjustment device is mounted to the rail and includes a second contact face facing the first contact face, two ridges, and a block. The block is located between the two ridges. The users can connect the adjustment device to the mount case of the chair back to quickly install the headrest unit to the chair back.

A head restraint assembly is provided with a head restraint frame mounted to a post for movement along the post for adjustment relative to a vehicle seat. The head restraint frame has a contact surface. A biasing member is mounted to the head restraint frame for movement relative to the head restraint frame to maintain the head restraint frame in a locked condition along the post. An actuation member is mounted to the head restraint frame for movement relative to the head restraint frame. The actuation member cooperates with the biasing member such that movement of the actuation member moves the biasing member, thereby disengaging the biasing member from the post to permit movement of the head restraint along the post such that the biasing member engages the contact surface in the second position to provide feedback to the user of an unlocked condition of the head restraint frame.
