Abstract: When a vehicle is rear-ended and a seated user moves rearward in reaction to the rear-end collision, a load generated by a rearward movement of a lumbar part of the seated user is sufficiently transmitted from a pressure plate (10a; 20c) of operating force generating means (10) to an operating force generating mechanism (10B), regardless of an amount of rearward tilting of a seat back (3). Then, a pressure roller (10P) serving as a driven member of the operating force generating mechanism (10B) largely deflects and sufficiently pulls inner cables (11B, 11B) of respective pulling cable devices (11, 11), thereby smoothly moving both end portions of a headrest frame (7) upward. As a result, the headrest frame (7) is moved upward smoothly and reliably, and a headrest (4) is moved in an upward-forward direction, that is, toward the head of the seated user smoothly and reliably.

Abstract: When a vehicle is rear-ended and a seated user moves rearward in reaction to the rear-end collision, a load generated by a rearward movement of a lumbar portion of the seated user is transmitted from a pressure plate (10A) of operating force generating means (10) to an operating force generating mechanism (10B). Then, a pressure roller of the operating force generating mechanism (10B) deflects and pulls inner cables of pulling cable devices (11, 11), thereby moving both end portions of a headrest frame (7) upward. As a result, the headrest frame (7) is moved upward along with headrest supporting brackets (7C, 7C) smoothly and reliably, whereby a headrest (4) attached to the headrest supporting brackets (7C, 7C) with headrest stays (4A, 4A) arranged between the headrest (4) and the respective headrest supporting brackets (7C, 7C) is moved in the upward-forward direction, that is, toward the head of the seated user smoothly and reliably.

Abstract: PROBLEM TO BE SOLVED: To provide a vehicular seat with a lower frame to be deformed constantly at its position and in its direction upon rear collision. SOLUTION: The vehicular seat comprises the lower frame 101 provided on a floor side, on which a seat cushion is arranged, an upper frame 103 rotatably provided on the lower frame 101, on which a seatback is arranged, and a reclining mechanism 102 for prohibiting/permitting the rotation of the upper frame 103. The peripheral edge of the lower frame 101 at the lower part of the reclining mechanism 102 is provided with a bent offset portion 121 protruded to one of the outside and the inside of the lower frame 101 and a reinforcing bent flange portion 111 formed almost all over the peripheral edge of the lower frame 101.

Abstract: A vehicle footrest system is obtained that allows an occupant seated in a rear seat to brace their feet when a footrest section is employed during travel, and that is capable of inhibiting load from concentrating at the heels of an occupant. A footrest system (38) is provided with: a reclining device (40) that rotates an upper end part side of a seatback (22) in the direction of arrow A and holds it at a predetermined angle of rotation; and a slide device (50) that slides a front seat (16) in the direction of arrow B with respect to a vehicle body floor (14). When an occupant (5) seated in a rear seat (18) uses a footrest portion (48) of the seatback (22), the reclining device (40) is operated and the upper end part side of the seatback (22) is inclined toward the vehicle front side. Further, the slide device (50) is operated and a slide portion (54) of a seat cushion (20) is moved in a vehicle front-rear direction along a rail portion (52). In this state, feet (5A) can be placed at the footrest portion (48).

Abstract: PROBLEM TO BE SOLVED: To provide an occupant's waist restraint system having a simple structure which is capable of enhancing the occupant restraint performance and enhancing the ride quality performance of an occupant on a vehicular seat by preventing occurrence of a submarine phenomenon. SOLUTION: A boomerang-shaped restraint member 48 having an interference part 48A and a push-up part 48B is arranged rockingly around a spindle 50 below a front part of a seat cushion frame 38. The interference part 48A of the restraint member 48 is abutted on a back side of an inclined surface 44A of a seat pan 42 by the urging force. When a vehicle is collided, a lower portion 60B of a waist of an occupant is inertially moved forward of the vehicle, and the seat pan 42 slides forward, the interference part 48A is pressed, the restraint member 48 is rocked around the spindle 50, and the push-up part 48B pushes up a seat cushion to increase its rigidity.

Abstract: PROBLEM TO BE SOLVED: To provide a seat for a vehicle having a headrest capable of effectively constraining a head part at the time of a collision. SOLUTION: A seat back 12 has a support bracket 60 for inserting a stay 15 of the headrest 13, an upper frame member 32 for supporting a back face 60a of the support bracket 60 to be movable in the vertical direction, a headrest driving mechanism 67 and a pressure receiving member 70. The headrest driving mechanism 67 includes an oblong bracket 51 having a guide hole 50, a slide member 58 inserted into the guide hole 50 and a pressing member for bringing the slide member 58 into contact with an upper side part 50c of the guide hole 50. To constitute the pressing means, a wire 44 connected to the slide member 58 is obliquely extended to the upper side part 50c side by forming an angle α1 with the upper side part 50c of the guide hole 50.

Abstract: PROBLEM TO BE SOLVED: To provide a seat for a vehicle capable of securing the slidability of a headrest driving mechanism of a sliding structure and preventing lowering head part constraint property at the time of a collision. SOLUTION: A seat back 12 has a support bracket 60 for inserting a stay 15 of a headrest 13, a sliding guide bracket 65 for supporting the support bracket 60 to be movable in the vertical direction, and a headrest driving mechanism 67, etc. The headrest driving mechanism 67 drives the support bracket 60 to incline to a front side, while the support bracket 60 moves from a reference position toward an ascending position when a pressure receiving member 75 moves to a rear side. The sliding guide bracket 65 is provided with a pressing part 70 and a horizontal direction regulating part 71. The pressing part 70 energizes the support bracket 60 toward an upper frame member 32.
