摘要： A vehicle seat device is designed to perform tilt adjustment of a seat cushion in a construction which is high in rigidity, downsized and high in the quality of external appearance. The device comprises rotational links; floor attached front brackets and front swing links which make couplings between first joint portions of the rotational links and upper rails; flank brackets coupled to the rotational links at front portion thereof; floor attached rear brackets and rear swing links which make couplings between rear portions of the flank brackets and the upper rails; a front drive device secured to one of the flank brackets for rotationally driving the rotational links; and cushion frames coupled to the flank brackets and second joint portions of the rotational links respectively at rear portions and front portions thereof. The second joint portions and the cushion frames are coupled to respective both ends of cushion frame swing links.

摘要： To be able to store a seat back and a seat cushion in line from front to back and be able to widely ensure space above a storage position of the seat cushion.In a rear seat (10), when a seat back (18) is rotated to a forwardly collapsed position in a state where a seat cushion (16) has been moved to a storage position, the seat back (18) and the seat cushion (16) are stored in parallel from front to back. Consequently, the seat back (18) and the seat cushion (16) can be thinly stored in an up-down direction of a vehicle. Moreover, the storage position of the seat cushion (16) is set on a rear lower side of a use position, so space above the storage position can be widely ensured.

摘要： A vehicle seat device includes a seat cushion frame and a seatback frame including a lower-side frame supported at a lower end portion thereof to be tiltable relative to a rear end portion of the seat cushion frame, an upper-side frame arranged at an upper portion of the lower-side frame, and a center bending mechanism coupling the lower-side frame and the upper-side frame to be bendable forward, wherein the center bending mechanism bends the upper-side frame about a rotational center that is ahead of a seatback outer layer covering a front surface of the seatback frame. The movement of the upper-side frame when tilted comes close to the movement of the passenger who bends forward. The slip between the seatback outer layer and the back of the passenger can be minimized, and thus, it becomes possible to lessen an uncomfortable feeling of a passenger.
