A headrest adjusting bracket surrounds posts from the headrest. A screw displaces one side of the bracket to apply a frictional force to the headrest posts. Protrusions on the interior surface of the bracket, proximal to each post, increases the surface area contact between the bracket and the posts when the screw is tightened.

A headrest (1) for a vehicle includes a main element (2) on which a wing element (3) is mounted by means of a hinge (4) so as to be rotatable about a substantially vertical axis. So as to create a frictional locking function, the hinge (4) includes a shaft (41) with a projection (43) as well as a bush (42) with a receptacle (44) that is associated with the projection (43). The shaft (41) is mounted in the bush (42), and in a locked position the projection (43) engages into the receptacle (44).

A device for reducing a kinetosis-related disorder in a driving mode of a vehicle includes a vehicle seat with a headrest and an actuator system. The vehicle seat and/or the headrest is adjustable by the actuator system to position the headrest relative to a head of an occupant on the vehicle seat. A support region of the headrest includes a material which is elastically switchable and the material is solidifiable when a pressure is exerted on the material such that the material stiffens when the head of the occupant sinks into the support region.

A head restraint (14) has a headrest (16) and at least one guide tube (18) that can be latched to a backrest structure of a motor vehicle seat for movable guidance of the headrest (16) in the direction of travel. An actuating rod (30) is mounted rotatably in the guide tube (18) and an unlocking slide (40) can be moved axially by rotating the actuating rod (30). In an actuating position, the unlocking slide (40) moves a latching element (58) into an unlatched position, and, in a rest position, the latching element (58) occupies a latched position. An actuating bar (24) is guided in the headrest (16) for rotating the actuating rod (30). The guide tube (18) is supported axially without tilting, and protectively accommodates a latching mechanism (59) that is easy to actuate from outside so that the head restraint (14) can be adjusted in a simple manner.

A cover material, in particular a seat cover material, having an upper side and a lower side and at least one seam that runs over at least a part of the cover material and that is visible on the upper side. An electrically conductive element that generates an electric field is arranged on the lower side in the region where the seam runs.

A head restraint travel accessory that stabilizes a user's head when sleeping in a seated position. A harness system attaches to a seat or chair using one of two configurations of straps, cobra or butterfly, depending on the construction and size of the seat. Once the harness is attached, an adjustable head restraint band holds the passenger's head in a fixed position and is attached to the harness. A contoured pillow is positioned on top of the harness and is between the harness and the neck and head of the passenger. The head restraint travel accessory is ergonomically designed to hold a person's head and neck in the optimal position for vertebrae alignment when they are sleeping in a chair, so they will not be awakened by the vestibular response that occurs when the head bobs from side to side or front to back thus waking the person.

A pneumatically adjustable seat includes a seat frame having a seat back frame portion and a headrest coupled to the seat back frame portion. The headrest includes a resilient cushion. A drive assembly includes a contact member operatively associated with the resilient cushion. A first bladder is operatively coupled to the contact member and in fluid communication with a source of pressurized fluid. Inflation of the first bladder via the source of pressurized fluid extends the contact member from a first position nearer the seat back frame to a second position further from the seat back frame. A second bladder is operatively coupled to the contact member and in fluid communication with the source of pressurized fluid. Inflation of the second bladder via the source of pressurized fluid pivots the contact member away from an occupant of the seat.

An adjustment device includes a housing in which a rotary element is rotatably mounted about a rotational axis, a locking device having a first locking element, connected in a rotationally fixed manner to the rotary element, and a second locking element arranged on the housing and which can be reversibly moved between a primary position in a locked situation, in which the locking elements have a form- and/or force-locking connection, and a secondary position without the connection. An adapter plate is rotates relative to the rotary element and the housing. An unlocking element cooperates with the adapter plate in an actuator region when the second locking element is transferred into the secondary position. The second locking element is shifted by an unlocking height in the unlocking region, and by a lifting height in the actuator region. The actuator region is arranged with the lifting height smaller than the unlocking height.
