A vehicle seat includes a seat cushion, a seatback, and a headrest. At least one of the seat cushion, the seatback, and the headrest includes a fixed part and a movable part. The fixed part and the movable part that is mounted so as to be movable relative to the fixed part are provided adjacent to each other. A border between the movable part and the fixed part is exposed to an outside of the seat. A movable-side edge of the movable part and a fixed-side edge of the fixed part are disposed adjacent to each other along a direction of movement of the movable part so as to form at least a part of the border exposed to the outside of the seat. The movable part moves relative to the fixed part while keeping a constant clearance between the movable-side edge and the fixed-side edge.

A height-adjustable headrest may have a base support element and a supporting element. The supporting element may be arranged in the base support element. The supporting element may be guidable in a longitudinally displaceable manner in an X direction. In order to form a guide, the basic supporting element may have a number of openings and the supporting element may have a number of guide parts. A shape of the number of openings may correspond to a shape of the number of guide parts.

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.

A seat with a headrest for a locomotive means includes a carrier or support system for a backrest of the seat, a support element having an installation section, and a guide device. The headrest has a headrest box, wherein the installation section of the support element is arranged on the support system in a stationary manner in the region of the headrest. The headrest box is movably arranged on the guide device, and the headrest box can be locked relative to the guide device in a movement direction.

Described is an adjustable friction slider assembly having a rail member and a carriage assembly moveably coupled to the rail member, the carriage assembly having a bracket member and a plurality of roller elements moveably coupled to the rail member and coupled to the bracket member using a plurality of attachment members, the plurality of roller elements comprising at least one adjustable roller element coupled to the bracket member using a moveable attachment member, wherein moving the moveable attachment member adjusts a friction between the plurality of roller elements and the rail member.

A headrest device that integrates with vehicle's seats for providing persons with a device for resting ones head when traveling as a passenger in a vehicle, the headrest device including a headrest assembly that removably mates with a mount assembly.

A seat (1) for transport vehicles with an articulated frame (2) capable of moving and changing shape between a neutral position N and a comfort position C, which comprises a headrest portion (21) mechanically linked by means of a connector (22) to a connection area of a backrest portion (23) that changes the height position thereof as the frame (2) moves from the neutral position N to the comfort position C thereof, the connector (22) being suitable for this change in height position to be transmitted, by means of mechanical drag, to the headrest portion (21), the headrest portion (21) being mechanically linked by means of an upper guide unit (31) of a guide system to the chassis (4) which is configured such that the inclination of both the headrest portion (21) and the backrest portion (23) increase the inclination thereof with respect to the vertical as the frame (2) moves from the neutral position N to the comfort position C thereof.

An adjustable headrest for motor vehicle seat. The headrest includes a support structure fixed to a backrest and a body having a front shell and a rear shell. The front shell has a front face intended for contact with the head of a user of the seat, the front face being movable relative to the support structure along a front-rear direction denoted X, over a total travel distance. The total travel distance is formed by a first travel portion provided by a mounting enabling translational movement of the body relative to the support structure while maintaining the position of the front shell relative to the rear shell substantially constant. The total travel distance is also formed by a second travel portion provided by a mounting enabling translational movement of the front shell alone relative to the rear shell.

The technology can be embodied in a headrest that includes an enclosure that includes one or more acoustic transducers. The headrest includes a bar for mounting on a backrest of the seat, such that the mounted headrest is movable with respect to the backrest to different positions over an adjustable range. The bar includes one or more wires each of which is coupled to an electrical contact at one end, and an acoustic transducer at an opposite end, the one or more wires disposed within a hollow interior portion of the bar. The bar also includes an opening for permitting an electrical connection to be established between an electrical connector coupled to an external source, and the electrical contact coupled to the one or more wires. The connection is maintained over the adjustable range of the headrest by a mechanical bias on either the electrical connector or the electrical contact.
