A longitudinal adjuster for a seat, in particular vehicle seat, may have at least a fixed lower track and an upper track slidable coupled to the lower track, an adjustment device for longitudinally adjusting the upper track relative to the lower track, a latch mechanism to latch the upper track relative to the lower track, and an electromechanical device relatively coupled to the latch mechanism. The electromechanical device may be configured to bias the latch mechanism between a release position and a latch position, and upon release of the latch mechanism the adjustment device is actuated to drive the upper track relative to the lower track.

Provided is a belt assist device having a compact configuration and being configured to move a seatbelt to an easily reachable position. A vehicle seat includes a belt assist device attached to a lateral portion of a seat back and configured to move a portion of a seatbelt placed on the lateral portion to the easily reachable position. The belt assist device includes a rotary member attached to a recessed housing portion of the lateral portion via a rotary shaft and configured to rotate up and down between a housing position at which the rotary member is housed in the seat back and a protruding position at which the rotary member rotates to protrude forward of the seat back to push out a portion of the seatbelt. The rotary member is disposed forward of a belt guide provided at the periphery of an upper end of the seat back.

A seat adjustment apparatus for mobility includes a seat cushion, wherein, during seat cushion tilting, the front portion of the seat cushion is moved upwards, and the rear portion thereof is moved downwards so that the occupant's lower body is not moved upwards as a whole, and the occupant's feet are not excessively lifted. Accordingly, there is no need for a separate footrest for supporting the occupant's feet, and seating convenience is improved by implementing a stable occupant posture. Furthermore, a tilting bar provided for seat cushion tilting supports a seat frame so that the posture of the occupant's lower body does not collapse due to deformation of the seat cushion during a collision, securing the occupant's stability.

A support for a headrest may have a single-part bending joint support which may have two support regions. A first support region may be situated in a backrest, and a second support region may be designed to receive a headrest body. Also included is a headrest for a seat, including a vehicle seat, that may have at least one headrest body and a support mentioned above and a seat.

A vehicle seat comprising a seatback mounted pivoting by an articulation mechanism selectively lockable and unlockable, relative to a seatback footing selectively lockable and unlockable on a base, where the seat further comprises a seat cushion, first and second rear connecting rods connecting the seatback to the base, an actuating device being configured, by rotation of the first rear connecting rod, for driving the seatback into a folded down position when the articulation mechanism is unlocked and the seatback footing is locked on the base, and for driving the seat in a forward tilted position when the seatback footing is unlocked and the articulation mechanism is locked.

A support mechanism for a vehicle seating assembly includes a seat frame moveable between a sitting position and a standing position and a support bracket coupled to a vehicle floor. A linkage assembly extends between the support bracket and the seat frame. The linkage assembly is positionable between a collapsed position if the seat frame is in the sitting position and an extended position if the seat frame is in the standing position and includes a first end rotatably coupled to the support bracket and a second end slidably coupled to the seat frame. A pawl assembly is engageable with the linkage assembly and positionable in an unlocked position if the linkage assembly is in the collapsed position and a locked position if the linkage assembly is in the extended position.

A sliding unit for a vehicle includes: a rail having a bottom surface, both side surfaces and a top surface, the rail configured to extend in a front-rear direction, be bent, and then extend in a left-right direction; a moving part slidably disposed on the rail to slide along the rail to move in the front-rear direction or in the left-right direction; a magnetic force part disposed in the moving part and configured to be locked to or unlocked from the rail through a magnetic force; and ground parts disposed on the moving part, electrically connected to the magnetic force part, and grounded with the rail to supply power from the rail to the magnetic force part.

A sliding unit for a vehicle, the sliding unit may include a rail provided on the vehicle; a fixing portion formed of a material through which magnetism is flowable and provided along a direction in which the rail extends; a moving portion that is slidable along the rail; and a magnetic module provided in the moving portion, disposed toward the fixing portion, and selectively locked to the fixing portion by a magnetic path to selectively fix the moving portion to the rail.

A moving and locking device for a vehicle seat includes: a lower frame mounted on a bottom surface of a seat cushion; a plurality of wheels disposed underneath the lower frame in such a manner that the plurality of wheels roll on a floor panel; and a vacuum adsorption device disposed inside the lower frame and configured to be adsorbed on the floor panel by vacuum force. The vehicle seat is configured to be moved to the desired position through the rolling motion of the plurality of wheels, and configured to be locked at the desired position through vacuum adsorption of the vacuum adsorption device on the floor panel.
