Abstract: To expand a body weight adjustment range and achieve thinning. An initial position adjusting member 15 which can adjust initial resilient forces of two torsion bars 31, 41 is provided. Therefore, a body weight adjustment range is expanded as compared with a conventional configuration where a resilient force of only one torsion bar is adjusted.

Abstract: A reclining adjuster has a lower bracket fixed to a seat cushion; an upper bracket fixed to a seatback and connected to the lower bracket so as to be rotatable about a shaft; a lock mechanism capable of having a locked state where rotation of the upper bracket relative to the lower bracket is locked and a released state where the lock is released; and an emergency lock mechanism for preventing relative rotation between the lock mechanism and the upper bracket when it occurs. In the emergency lock mechanism, when a cam projection of an outer toothed ring gear is pressed in the circumferential direction by a cam pin of a disk member by the relative rotation therebetween, the outer toothed ring gear meshes with both inner teeth of the lower bracket and inner teeth of the upper bracket.

Abstract: Reduces backlash and clearance in a thrust direction of a worm when engaging a seat back to more securely prevent the generation of abnormal noise that before. A movable bearing 12 is pressed by cams 21, 22 that are pressing members, when the seat back is stopped at a predetermined angle, to approach a worm wheel 5. A ball 14 disposed in a recess 12a of the movable bearing 12 moves slightly along an inner surface of the recess 12a so a worm 4 is pressed to the worm wheel 5 side and pressed to the fixed bearing 11 side, and a latch member 23 that is a engaging member engages the worm 4 to inhibit rotation of the worm wheel 5 thereby securely holding that state. Since the movable bearing 12 moves to the worm wheel 5 side, the substantial movement range of the ball is wider compared to a structure that supports a ball only at a fixed bearing, and the range of displacement of the worm 4 by being pressed by the ball is substantially larger.

Abstract: A seat structure applicable to both a normal posture and a comfortable posture, in which a sufficiently relaxed resting posture is available and an excellent comfort is obtained while seated. A cushion frame is supported by a rear link plate and a front link plate, set such that the rear link plate within its movable range has a displacement angle larger than a displacement angle of the front link plate, and an angle between a side frame portion of a base frame and the rear link plate becomes smaller than an angle between the side frame portion and the front link plate when the plates are rotated and moved to the forward-most positions. Consequently, a seating surface angle of the cushion frame increases as the rear link plate and the front link plate are rotated and moved forward. An inclination angle of a back frame itself does not vary but the seating surface angle of the cushion frame can be varied according to a movement of a person.

Abstract: A seat height adjusting device includes first and second brackets spaced away from each other, an arm disposed between the first and second brackets and having first and second ends pivotally mounted on the first bracket and a seat support, a spur gear operable to rotate the arm, first and second latches engageable with the spur gear, and a handle rotatably mounted on the first or second bracket. One of the first and second brackets is joined to a seat frame. When the seat is raised, the handle is operated to intermittently engage the first latch with the spur gear, thereby rotating the spur gear in a first direction to drive the arm. To lower the seat, the handle is operated to intermittently engage the second latch with the spur gear, thereby rotating the spur gear in a direction opposite the first direction to drive the arm.

Abstract: A recliner adjuster for appropriately adjusting an inclination of a seat back with respect to a seat cushion includes a worm rotatably mounted on the seat cushion, and a helical gear held in engagement with the worm and mounted on the seat back via an auxiliary locking mechanism. The auxiliary locking mechanism includes a pair of external gears connected to the helical gear and held in engagement with a portion of the seat back, and a pair of internal teeth mounted on the seat cushion so as to accommodate the pair of external gears therein, respectively. During normal use, the seat back is held at a predetermined angle with respect to the seat cushion by the engagement of the helical gear with the worm, while when a load greater than a predetermined value is inputted to the seat back, the pair of external gears are partly deformed to engage with the pair of internal teeth, respectively, to thereby hold the seat back at the predetermined angle with respect to the seat cushion.

Abstract: The object of the present invention is to suppress rebound of a human body when receiving a large impact load accompanying a collision or the like. A back frame member 20 and a seat frame member 10 are individually formed by welding or caulking, and a link member 30 for connecting both is attached to the back frame member 20 and the seat frame member 10 by welding or caulking. Each of the frame members is provided with a cushioning member as a tension structure. Upon receipt of an impact vibration or an impact force at a predetermined magnitude or more, the tension of the cushioning member provided as the tension structure lowers to be able to exhibit high damping characteristics.

Abstract: In order to improve vibration absorbency and impact absorbency, the seat structure includes a swing member provided in a manner to be able to swing at least back and forth on a rear frame member positioned around the rear of a seat cushion, a pelvis supporting member connected to the swing member at the vicinity of the lower portion of the pelvis supporting member and disposed behind the pelvis of a seated person, and coil springs as an elastic member to support the pelvis supporting member biasing in the direction pushing forwards in a normal seating state. Accordingly, vibration inputted from the seat back side and as if patting on the back of the human body can be absorbed by the pelvis supporting member supported elastically.
