The seat selectively performs one function of a walk-in function, a relaxation posture change function, and a seatback full-flat folding function through the one integrated mechanism.

Abstract: An apparatus for rotating a headrest of a vehicle seat includes a headrest that is rotated forward to support a seat occupant's head upon reclining of a seatback. A seat occupant's head is comfortably supported by the headrest and a comfortable relaxation posture is implemented.

Abstract: Disclosed is a vehicle seat adjustment device including a seat-cushion-tilting frame disposed on a moving rail, the moving rail being coupled to a fixed rail so as to be movable forwards and backwards, and connected to a seatback frame, a tilting device hingedly coupled to a base bracket on the moving rail and to a rear end of the seat-cushion-tilting frame to perform forward tilting of the seat-cushion-tilting frame, a locking device connected to the tilting device to lock and unlock the tilting device, and a probe rotatably disposed between the seatback frame and the tilting device, the probe including a stopper capable of being inserted into a locking groove formed in the seatback frame.

Abstract: Disclosed is a seat for a vehicle configured to variously adjust a seat position between, for example, a full-flat mode, a relaxation mode, a cushion tip-up mode, a full-bed mode, a walk-in mode, and a rear-view mode using a first hinge shaft to rotate the entire seat, including a seatback and a seat cushion, and a second hinge shaft to rotate the seatback.

Abstract: The present disclosure relates to a vehicle seat wherein matchability with a luggage box is maintained when the seat is folded, and a relax mode and a backward relax mode can be implemented. The vehicle seat according to the present disclosure includes: a tilting link configured to tilt a front portion of a seat cushion upwards/downwards; and a sliding bracket having one end to which a seat is connected by a hinge structure such that the seat is tilted around the hinge structure, the other end of the sliding bracket being connected so as to slide forwards/backwards.

Abstract: A walk-in apparatus for a vehicle seat includes a walk-in bracket rotatably coupled to a crossbar of a cushion frame and operable to release a fixing member by contacting the fixing member of a seat rail; a compensator bracket operably connected to the walk-in bracket through a hinge, the compensator bracket also being connected to a walk-in cable; and a compensator spring configured to support the walk-in bracket and the compensator bracket, rotate at least one of the walk-in bracket and the compensator bracket, and operate in such a manner as to return the compensator bracket. Even when the walk-in cable is released due to a seatback rebound phenomenon during a walk-in operation, the walk-in bracket maintains a pressing state of the fixing member to maintain continuously an unlocking state of the seat rail, allowing the vehicle seat to move forward smoothly to enable a walk-in operation.

Abstract: 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.

Abstract: A duct for a ventilation seat of a vehicle includes a seat cushion duct and a seatback duct that are interconnected so as to communicate with each other via a telescopic sliding duct. The telescopic sliding duct is variable in length in a forward-backward direction such that a length of the telescopic sliding duct interconnecting the seat cushion duct and the seatback duct may be increased when the seatback is folded, and the length of the telescopic sliding duct interconnecting the seat cushion duct and the seatback duct may be reduced when the seatback is unfolded. Because the telescopic sliding duct can vary in length, it is possible to avoid damage due to a load applied to the telescopic sliding duct by folding and unfolding operations of the seatback. Further, it is possible to easily supply air to the seatback and the seat cushion without leakage of air.
