A rear seat apparatus for a vehicle includes a back frame and a cushion frame. The back frame is not interlocked with the cushion frame and is individually rotated in the forward-and-rearward direction independently of the cushion frame. The cushion frame is not interlocked with the back frame and individually slides in the forward-and-rearward direction independently of the back frame. A front seating state and a rear seating state of a passenger are implemented through individual sliding movement of the cushion frame in the forward-and-rearward direction.

A locking device for a vehicle walk-in seat includes: a seat cushion part mounted on a movement rail of a seat rail and configured to slidably move along the seat rail, a rear link having a side mounted on a rear portion of the seat cushion part and another side mounted on a rear side of the movement rail, a front link having a side mounted on a front portion of the seat cushion part and another side mounted on a front side of the movement rail of the seat rail, a locking part locked with the rear link or the front link, and a switching guide part mounted on a lower portion of the seat cushion part and configured to move in a state of being seated on a slide guide provided on a fixed rail of the seat rail.

A device for height adjustment and swivel of a seat for a vehicle has a structure in which a first motor for height adjustment of the seat, a first reduction gear device for increasing output torque of the first motor, and a lifting device configured to lift or lower the seat by being connected to the first reduction gear device are stacked in a vertical direction, and a second motor for driving of seat swivel, a second reduction gear device for increasing output torque of the second motor, a brake device configured to stop the seat are vertically stacked between a bottom of the seat and the first motor, in order to adjust the height of the seat, enable accurate swiveling, and carry out a monopost function of the seat.

The present disclosure relates to a seat rail which includes: a lower rail; an upper rail; and a locking unit, and the locking plate may include: a plate body; and a plurality of locking protrusions provided in the plate body, inserted into and fixed to the inserting hole, and selectively fastened to the locking hole, and the locking protrusion may include a support lock supporting one among the upper rail and the lower rail, and having one contact point supporting the upper rail or the lower rail, thereby minimizing a clearance and a flow of the seat rail in a forward-rearward direction.

A locking device is disclosed of a seat back capable of preventing generation of a clearance between a striker and a latch. The locking device of a seat back includes: a hinge pin installed in a case; a first latch part rotatably installed through the hinge pin with respect to the case and having a fork for coupling to a striker; a second latch part rotatably installed through the hinge pin with respect to the case and having a restraint for preventing a flow of the striker; an interlocking structure for an interlock behavior between the first latch part and the second latch part; a first return spring configured to provide a restorative force in a locking direction with respect to the first latch part; and a second return spring configured to provide a restorative force in a locking direction with respect to the second latch part.

The present disclosure relates to a release actuator capable of selectively converting at least one among a walk-in locking mechanism and a folding locking mechanism into a released state from a locked state according to a rotational direction of a rotational unit. The release actuator of a vehicle seat includes: a pair of first cables installed to release a walk-in locking mechanism; a second cable installed to release a folding locking mechanism; a rotating unit configured to apply tension independently and respectively to the first cable and the second cable based on a forward rotation and a reverse rotation; and a driving unit configured to provide a rotational force to the rotating unit in a forward direction and a reverse direction, and the rotating unit may include a forward interlocking rotating part configured to provide tension to one among the first cable and the second cable based on a forward rotation; and a reverse interlocking rotating part configured to provide tension to another one among the first cable and the second cable based on a reverse rotation.

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.

An embodiment relaxation seat for a vehicle includes a seat cushion lower frame configured to be mounted on a seat rail, a seat cushion upper frame connected to the seat cushion lower frame in a tilting-enabled manner, a seat back frame connected to the seat cushion upper frame, a locking device mounted at a predetermined position on the seat cushion upper frame, a front link hinge-connecting between the seat cushion upper frame and a front end portion of the seat cushion lower frame, a rear link hinge-connecting between the seat cushion upper frame and a rear end portion of the seat cushion lower frame, and a support bar connecting between the locking device and the front link in a manner that is movable backward and forward and configured to support the front link for rotation or fixation thereof.

A power swivel apparatus of a seat for a vehicle includes a motor having an eccentric shaft, a reduction gear device connected to the eccentric shaft of the motor, a brake device configured such that braking of the brake device is released by eccentric rotational force of the reduction gear at a time of driving the motor and the brake device exhibits braking force configured to stop the seat at a time of stopping driving of the motor, and a swivel plate connected to the brake device and configured to transmit rotational force so as to swivel the seat.

A height adjustment device and a swivel device for a vehicle seat are configured to adjust seat height and swivel the vehicle seat. The height adjustment device includes a first reduction gear device disposed at a bottom of the vehicle seat and configured to increase output torque of a first motor and a lifting device engaged with the first reduction gear device and configured to move the seat upwards or downwards, and the swivel device includes a motor driving unit disposed at a bottom of the height adjustment device and a second reduction gear device configured to increase output torque of the motor driving unit, thereby making it possible not only to selectively perform seat height adjustment and swivel operation, but also to perform a monopost function of the seat in a state in which the height adjustment device and the swivel device are stacked in a vertical direction.
