Abstract: A vehicle-mounted seat device includes an SB main frame, a back rest which the back of a seated person leans on, a relay disc fixed to the back rest, a first engagement member fixed with respect to the SB main frame at a position higher than the relay disc, an upper wire for suspending and holding the back rest from the first engagement member so as to be able to swing with respect to the SB main frame with the relay disc being the center, and a height adjustment mechanism constructed to be capable of pulling in part of the upper wire, so that an amount by which the upper wire is pulled in is changed to cause a change in disposed height of the back rest with respect to the SB main frame.

Abstract: A vehicle-mounted seat device includes an SB main frame, a backrest, an SB subframe, and one or more front-back position regulation mechanisms for regulating the position of the SB subframe in the front-back direction relative to the SB main frame. Each front-back position regulation mechanism includes a front restraining bracket secured relative to the SB main frame, a rear restraining bracket secured on the SB subframe, and a front-back wire strung between the front and rear restraining brackets. The rear restraining bracket is deformed such that its front end portion is displaced rearward relative to its end portion upon input of a load greater than a predetermined load. A maximum pulling load of the front-back wire is greater than a load that causes initial deformation of the rear restraining bracket.

Abstract: A seat cushion is swingable about an axis A with respect to a seat cushion support frame that is a part of a main frame. A cushion return spring that is a flat spring is disposed between the seat cushion and the seat cushion support frame so that an elastic force of the cushion return spring returns the seat cushion to a neutral position. A pair of clamp rollers that clamps the cushion return spring is disposed. The clamp rollers are movable along a longitudinal axis of the cushion return spring. Changing of a clamping position by moving the clamp rollers changes an effective length of the cushion return spring. In this way, a swingable range of the seat cushion and a force to return the seat cushion to the neutral position are changed.

Abstract: A headrest is supported by an upper lateral member and a lower lateral member of a seat frame. A headrest stay is inserted through each of guide slots, both of which are formed in both the upper lateral member and the lower lateral member, and an extension wire is hooked on a lower end of the headrest stay. In a rear-collision, a seat back is retreated by a force received from a seated passenger, and a tension of the tension wire is accordingly loosened, which causes the headrest to be tilted forward by an urging force of tilt springs.
