摘要： A swivel device for vehicle seats may rotate a seat mounted inside a vehicle at 180° or more and firmly fix the seat at a normal position before and after rotation. The swivel device includes: a base plate provided with a plurality of first locking members; a swivel plate disposed on the base plate to be rotated by a second motor; a rotary force transmission mechanism mounted on an output shaft of the second motor and the swivel plate to transmit a rotary force of the second motor to the swivel plate; an elevating plate provided with a plurality of second locking members separably coupled to the plurality of first locking members and formed on a lower surface of the elevating plate; and a first motor mounted on an upper surface of the elevating plate to transmit a rotary force to the lead screw.

摘要： The present disclosure provides a seat back including a bolster for a vehicle. The seat back may include a seat back frame including a side member formed on each of opposite sides thereof so that a left-and-right support of the seat back may be automatically adjusted. The seat back further includes a rotating plate having a structure integrally including an external plate extending into the bolster, and an internal plate extending inwardly into the seat back. 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.

摘要： 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.
