The receiving unit includes a reception controller that determined whether to drive a load based on the PWM signal and a switching unit that is turned on or turned off based on the determination of the reception controller.

Abstract: A seatback frame for a vehicle is capable of preventing a passenger seated on a seat from being injured by a sharp edge of a side frame in the event of a collision of the vehicle. The seatback frame includes side frames installed to extend longitudinally in a vertical direction at opposite sides of the seatback frame, respectively, an upper frame joined to the side frames, and a lower frame joined to the side frames. Protrusions are formed at a surface of the upper frame while being spaced apart, by a predetermined distance, from edges present at edge portions of the side frames, respectively, to prevent the passenger from being injured by the edges.

Abstract: A vehicle seat back may include an integrated suspension structure including a suspension wire and suspension mounting guides coupled to both sides of the suspension wire; and a seat back pad foamed for integrating with the integrated suspension structure in a state in which the integrated suspension structure is inserted into a mold for seat back pad formation.

Abstract: A lubrication device for an automatic transmission, the lubrication device includes: a pinion gear unit comprising a pinion shaft and a pinion gear surrounding the pinion shaft, a ring gear unit engaged with the pinion gear, a first thrust bearing coupled to the ring gear unit, a second thrust bearing disposed on one side of the pinion gear, an oil guide coupled to the pinion shaft and guiding the oil, scattering from the first thrust bearing, toward the pinion shaft, a sun gear engaged with the pinion gear and comprising a first oil hole portion through which the oil passes and a second oil hole portion allowing the oil to be supplied toward the second thrust bearing therethrough, and a carrier comprising a third oil hole portion receiving the oil from the first oil hole portion and transferring the received oil toward the first thrust bearing and a fourth oil hole portion receiving the oil from the second thrust bearing and transferring the received oil toward the oil guide.

Abstract: A seat track mechanism for installing beneath a vehicle seat in order to move the vehicle seat in the forward and backward directions includes a monotrack mechanism, to which a monopost structure and a single rail structure are applied. The seat track mechanism includes a structure for hook-engaging lower and upper rails constituting the mono track mechanism by hook guides. The single rail structure applied to the seat track mechanism is capable of not only reducing actuating force required for operation, but also preventing creation of excessive clearance upon stopping.

Abstract: A ventilation structure of a vehicle seat is configured to circulate indoor air of a vehicle through a seatback via a blower mounted on the seatback in a dual blower type of ventilation structure. This structure includes the seatback including a seatback pad having an exhaust hole and a seatback board having an intake hole, a seatback blower mounted on the seatback pad and providing a blowing force to introduce outdoor air of the seatback through the intake hole and then discharge the outdoor air to the exhaust hole, an intake duct mounted on the seatback board and providing a path to move the outdoor air of the seatback introduced into the intake hole, and a flexible duct connecting the seatback blower and the intake duct and deformable by a movement of the seatback while maintaining connection of the seatback blower and the intake duct.

Abstract: A side bolster adjustment apparatus of a vehicle seat may include a guide frame which is mounted to a seat back frame, and is formed with a guide groove; a slider which slides along a direction in which a bolster protrudes from a seat back, which is the longitudinal direction of the guide groove, by a guide means formed in the guide groove; a lead screw which is provided to penetrate the slider, and is mounted in the longitudinal direction of the guide groove; a motor which is coupled to the lead screw and selectively rotate the lead screw; and a bolster plate which is coupled to the slider, and rotates around a vertical longitudinal direction of the seat back by operation of the slider.

Abstract: A cup holder for a vehicle may include a holder body slidably coupled to a cup holder mounting portion in the vehicle, a finger elastically and pivotably mounted to the holder body, and configured to press and support a side surface of a cup inserted into the cup holder together with the holder body, a support connected to the holder body by a link such that the support is vertically movable in accordance with pivotal movement of the link, the support being configured to support a bottom portion of the cup, and a locking member disposed between the finger and the link, to lock the link, for prevention of pivotal movement of the link, or to unlock the link in linkage with pivotal operation of the finger.

Abstract: A seat swivel mechanism secured under a vehicle seat and configured to swivel the vehicle seat in a motor-driven manner is described. The seat swivel mechanism includes a lower plate, which is a fixed support body for supporting the swivel motion, and an upper plate rotatably secured on the lower plate. The upper plate and the lower plate are configured to rotate relative to each other, and the vehicle seat swivels due to the relative rotation of the upper plate and the lower plate. A driving motor is secured to any one of the upper plate and the lower plate, and an internal gear, which is secured to any one of the upper plate and the lower plate, is rotated by the driving motor, thereby swiveling the vehicle seat.

Abstract: A fold and dive seat for a vehicle is provided with a seat-cushion tilting mechanism, a fold and dive mechanism, and a seatback reclining mechanism so as to simultaneously performed both a seatback reclining operation and a tilting operation of a front portion of a seat cushion. The fold and dive seat reduces by evenly dispersing a body pressure over a passenger's upper body and lower body.

Abstract: A fold and dive seat for a vehicle that achieves a fatigue reduction posture is provided. The seat includes a tip up-extension mechanism that enables tipping-up and extension of the front end of a seat cushion and a seatback reclining mechanism for the fold and dive seat so that tipping-up for lifting the front end of the seat cushion and extension for extending the front end forward are performed simultaneously performed when the seatback reclining is performed.

Abstract: A backboard fastening device for vehicle seats capable of preventing the movement of a backboard attached to the rear surface of a seat and the generation of rattle noise due to the movement of the backboard includes a clip framework and a compressible and elastically restorable fastening clip. The clip framework is formed at a clip mounting end of the backboard. A fastening clip, which is configured to exhibit elastic restoring force when compressed, is mounted to the clip framework, thereby improving assembly durability of the backboard to a seat back, easily restraining the generation of assembly tolerance and rattle noise, and easily achieving separation of the backboard for maintenance.

Abstract: Disclosed is a ventilation mat for vehicles in which at least one exhaust hole configured to be spaced apart from a channel of a ventilation mat of a seat back and communicate with a covering layer is formed through the ventilation mat so as to form an exhaust air circulation structure to uniformly maintain ventilation performance of the seat back regardless of physical characteristics of a passenger seated on a seating part of the seat back. Therefore, through the exhaust air circulation structure, the ventilation mat for vehicles consistently inhales cooling air in a vehicle when the passenger is seated on the ventilation seat, and thus lowers the temperature of the seating part to improve passenger's thermal comfort.

Abstract: A seatback frame for vehicles is disclosed. The seatback frame for vehicles has a simple structure without bracket structures used to install a conventional seatback frame and thus achieves cost reduction and weight reduction. In particular, the seatback frame is segmented into several parts having different rigidities so that only a part, on which load is concentrated, is set to have high strength and thus avoids overdesign for excessively high strength of an unnecessary part.
