Abstract: A vehicle seat comprises a seat back frame having a pair of side frames, a seat spring mounted between the side frames, a single plate-shaped flexible cushion plate mounted to the seat spring, a seat back cushion provided in front of the cushion plate, a single plate-shaped flexible auxiliary plate mounted on the cushion plate. The auxiliary plate is located between the cushion plate and the seat back cushion. The auxiliary plate pushes the seat back cushion to the front by being forwardly bent in response to an operation member. A collision detector is located on the rear side of the cushion plate having a predetermined distance therebetween.

Abstract: The vehicle seat of the invention has an active headrest mechanism for moving the headrest forward in the event of a rear-end collision. The active headrest mechanism is composed of a headrest support part in lateral direction provided with a vertical engaging part for supporting a pillar of the headrest, and an upside link mechanism for moving the headrest support part ahead of the backrest, and the upside link mechanism is mounted on the upper frame of one plate of the backrest frame by way of a bracket.

Abstract: A vehicle seat of the invention includes: a rectangular-shaped seat back frame (5) having a pair of side frames (6); a plurality of seat springs (34A, 34B) disposed between the side frames; a single plate-shaped flexible cushion plate (31) attached to the seat springs; a seat cushion (9) provided on the front side of the cushion plate; link mechanisms (15, 35) provided near the side frames; and a headrest (4) coupled to the link mechanisms (15). Both ends of the seat spring (34B) are coupled to the link mechanisms. When the seat spring (34B) is moved rearward, the headrest is moved forward. Both sides of each of the remaining seat springs (34A) are mounted to the side frames.

Abstract: A vehicle seat comprises a headrest mounted on the seatback frame so as to be movable in a front-and-back direction, a cushion plate mounted on the seatback frame, and a collision detector provided at back side of cushion plate. The headrest is connected to the collision detector by way of a active headrest mechanism. When the collision detector is moved backward, the headrest is moved forward. A space part is formed between an upper edge of the cushion plate and an upper frame of the seatback frame. The space part is enlarged by forming the upper frame by a pipe frame.

Abstract: A backrest frame 5 is provided with a cushion plate 31 of one substantially square plate form positioned behind the waist from the upper part of the back of a vehicle seat occupant, movably back and forth by way of a plurality of upper and lower parallel seat springs, one end of either one of a pair of right and left seat springs 34B of the plurality of upper and lower parallel seat springs is connected to a pair of lower link mechanisms 35 provided rotatably on the backrest frame 5, and a rear end collision sensor 40 is formed by the cushion plate 31 between the seat springs 34B for moving a headrest 4 forward, and a coupling part 39 of the other end of the seat spring 34B is directly attached to the lower link mechanism 35.

Abstract: A vehicle seat of the invention has an upper movable member (10) supporting a headrest (3), a lower movable member (30) provided inside a backrest, and a coupling mechanism for coupling the upper movable member and the lower movable member. The coupling mechanism includes an upper link mechanism (15) positioned in an upper part of a side frame (40) and coupled to the upper movable member, a lower link mechanism (32) positioned in a lower part of the side frame and coupled to the lower movable member, and a rod (27) extending along the side frame and coupling the upper link mechanism and the lower link mechanism. The upper link mechanism amplifies a backward moving amount of the lower movable member, and moves the headrest forward.

Abstract: In an automobile seat provided with a seatback having a metal-made seatback frame of a substantially quadrilateral shape, the seatback frame comprising a pair of spaced apart left and right side frame sections 10a, 10b, an upper frame section 11 interconnecting upper end portions of the side frame sections 10a, 10b, and a lower frame section 12 interconnecting lower end portions of the side frame sections 10a, 10b, the lower frame section comprises a horizontally extending body arranged between the lower end portions of the side frame sections 10a, 10b, side bracket portions 12a, 12b provided at left and right ends of the horizontally extending body so as to project forward from the horizontally extending body, the side bracket portions 12a, 12b being applied and fixed to the lower end portions of the side frame sections 10a, 10b, and a structure for serving to facilitate deformation of the seatback in the event of a car crash or the like in order to absorb impact caused by the car crash or the like, the stru
