A boundary portion between the external plate and the internal plate of the rotating plate may be rotatably mounted to the side member of the seat back frame.

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.

Abstract: The present disclosure relates to a height adjustment apparatus of a vehicle seat, whereby during a height adjustment of a seat cushion, a desired tilting angle of the seat cushion is obtained and heights of a front part and a rear part of the seat cushion are individually adjusted.

In addition, a link connection is structurally secured and thus its durability is also improved.

Abstract: The present disclosure provides a multi-joint seat back for a vehicle, which may include a plurality of partitioned seat back components provided to have a structure in which a seat pad is inserted into a front portion of a skeletal frame and configured to be hinged to one another in a manner of rotating angularly in a forward or backward direction; elastic wires, each of which is connected between two partitioned seat back components selected from the plurality of partitioned seat back components; pulling wires bound to predetermined positions of the elastic wires respectively; and a drive unit connected to the pulling wires such that it winds the pulling wires to pull the elastic wires or otherwise releases the pulling wires to restore the elastic wires.

Abstract: A lumbar support apparatus for a vehicle seat includes: a seatback frame having an adjustable inclination angle; an operating mechanism disposed at an upper portion of the seatback frame, the operating mechanism including a connector generating an operating force in a vertical direction by being in contact with a fixture fixed to a vehicle body when the inclination angle of the seatback frame is adjusted; and a support mechanism disposed at a lower portion of the seatback frame, connected to the connector, receiving the operating force generated from the connecting mechanism, and configured to slide in a front and rear direction depending on an application direction of the operating force, such that when the inclination angle of the seatback frame is adjusted to be directed rearward, the support mechanism receives the operating force of the operating mechanism and is advanced forward to support a waist of an occupant.

Abstract: A side extension device for a seat of a vehicle, may include a seat cushion frame for forming a framework, a cushion pad provided with a bolster formed on each of opposite sides thereof, and a seat cover for covering a surface of the cushion pad, wherein a plurality of slits is formed in the bolster of the cushion pad, and divided bolster parts are formed between the slits, wherein the divided bolster parts are successively inclined outward by contact pressure of side parts of hips of an occupant, so that the bolster spreads outward.

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 device for swiveling and tilting a vehicle seat is provided. The device performs a swiveling operation to enable the vehicle seat to be rotated in a desired direction using a motor driving force and a gear/screw operating mechanism associated with the motor driving force. The device also performs a tilting operation to enable the vehicle seat to be tilted backwards by a desired angle using the motor driving force and a lead screw/link operating mechanism associated with the motor driving force.
