Abstract: An apparatus for adjusting the height of a vehicle seat. The apparatus includes an input shaft for inputting a torque by using a lever installed at one side of the seat; an output member connected to a link means to output the torque for adjusting the height of the seat; a clutch drum interposed between the input shaft and the output member on a torque transfer path; a torque transfer unit comprising a plurality of neighboring engagers wherein the engagers disposed at two ends of the torque transfer unit are spaced apart from each other, and wedge-combined between the input shaft and the clutch drum to transfer the torque; and an elastic member for providing an elastic restoration force for moving the torque transfer unit to its initial position. According to the present invention, since a conventional retainer may be omitted, backlash caused by a retaining clearance and an operation clearance may be prevented and thus an operational efficiency may be increased.

Abstract: Disclosed in the smart car seat manufacture method, which features in that the smart car seat is manufactured in such a way that the cushion pad assembly supporting the user's hips is assembled with the cushion cover covered on the cushion pad, and the back pad assembly is assembled, which supports the sit passenger's back with the light emitting raw sheet sewed on the back cover so as to form the portion which is exposed to the outside along with the back cover covered on the back pad. The smart car seat comprises the back frame, the cushion frame and the light emitting raw sheet processed along with the head rest by way of the finish process.

Abstract: The present invention relates to a reclining device of a seat for a vehicle, which makes it possible to prevent backlash between an external gear 12 and an internal gear 22 in stop, resulting in preventing a vibration noise due to movement of the seatback. Further, it is possible to obtain sufficient power from even a small-output motor in operation, by minimizing the gear press angle to increase the operational efficiency. In addition, it is possible to design a compact reclining device by simplifying the shape and reduce the size of assemblies of wedge blocks 70, 120 and cams 80, 110, resulting in reducing the weight and the manufacturing cost and making it possible to freely designing the reclining device, depending on a disposing space.

Abstract: The present invention relates to a pumping device for a seat cushion of a vehicle, in which a brake assembly 40 is disposed outside a clutch assembly 30 and parts are arranged in a line, such that it is possible to reduce the entire size, volume, and weight, thereby reducing cost. Further, because it is possible to prevent pollution of parts, it is possible to improve the durability, performance, and quality. Furthermore, it is possible to reduce operational noise and improve operational sensitivity.

Abstract: A reclining device of a seat for a vehicle is disclosed. With the disclosed device it is possible to prevent unexpected pivot of a seatback and improve the passenger's safety by maintaining the engagement of a sector tooth 20 and a pawl tooth 70 even if the pawl tooth 70 is separated from a rotational center protrusion 11 by a relatively large external force applied to the seatback.

Abstract: The present invention relates to a reclining device for seats in vehicles, which has improved engagement force between an upper tooth bracket and an operating part, improved overall strength and durability, and improved quality due to the improvement in the connection structure of pole gears and rear guide protrusions. Further, the reclining device provides improved ride comfort for the driver and passengers and prevents operational noise.
