摘要： Seat structure designed to reduce weight and improve various functions such as impact absorbency, vibration absorbency. A torsion bar arranged along a width direction, and an arm connected to the torsion bar and enforced in a direction of falling backwards in a normal state are provided in the rear of a seat cushion, and a cushioning member is arranged between a supporting frame supported by the arm and a front frame provided at the front of the seat cushion, whose front edge is vertically movable rotationally. When working a pedal or standing up, since the front edge of the front frame is forced to move in a downward direction by a leg portion, a haunch supporting portion of the cushioning member is relatively lifted upward, so that support force to lift up the haunches works.

摘要： A seat structure includes a torsion bar 12 disposed along the width direction, and an arm 13 which is connected to the torsion bar 12, enforced in the direction of falling backward at a normal state by the torsion bar 12 in the rear of a seat cushion 10, and disposed is a flat-type supporting member 15 between the supporting frame 14 supported by the arm 13 and a frame member provided in front of the seat cushion, being strained by the elastic force of the torsion bar 12. Through this structure, the spring characteristic to give an influence on comfortability and riding comfort at the time of being seated can be given by the torsion bar 12, so that the number of coil springs which have been necessary in the vicinity of the body side can be reduced or the use of the coil spring can be stopped.

摘要： A vibration generating mechanism includes at least first and second permanent magnets spaced from each other with the same magnetic poles opposed to each other. The first permanent magnet is coupled to a link mechanism so that the drive force of a drive source may be transmitted to the first permanent magnet via the link mechanism. A periodic and reciprocating movement of the first permanent magnet relative to the second permanent magnet changes the opposing area thereof, causing vibration of the second permanent magnet.

摘要： A vehicle seat includes a tension structure extended on a back frame with a configuration in which a natural frequency in the right-and-left direction of the back frame is set lower than the natural frequency in the front-and-rear direction. Thereby, the structure can easily deflect in the right-and-left direction. Therefore, since an impact load larger than a predetermined level inputted in the front-and-rear direction due to front-and-rear/pitching vibration or a rear collision and the like becomes a force of deflecting the back frame in the right-and-left direction, the vibration/impact energy is consumed by that, and moreover, rearward displacement of the back frame consumes vibration/impact energy. Thus, absorbing performances of the vibration/impact energy are higher than before.

摘要： A seat in which a cushioning member has a high following ability to a human body motion and which can efficiently damp a vibration inputted from the outside is provided. The seat is constituted to use a torsion bar 112 and to support a cushioning member of a seat cushion section 150 by a parallel link mechanism having a first link plate 113 pivotally supported by the torsion bar 112, a second link plate 116 disposed in correspondence with the first link plate 113, and a connection link plate 117 connecting the first link plate 113 and the second link plate 116, and operational directions of the first link plate 113 and the second link plate 116 are set to almost coincide with a vertical direction along a surface of a seat back section. Thus, a rotational motion following a human body motion generated by an external vibration input is performed, so that a relative motion between a human body and the cushioning member is small and a resonance peak is lowered, whereby a vibration absorption characteristic can be improved.

摘要： A seat structure capable of dealing with both a normal posture and a resting posture and providing sufficient relaxation in the resting posture while ensuring excellent comfortableness of an occupant.According to the present invention, a back frame 20 itself is fixed to a frame support 10 but a cushion frame 30 shifts from a first position A to a second position B according to an occupant's movement and an inclination angle of a pelvis support 31 increases accordingly. The occupant's pelvis portion and a portion lower than the pelvis portion is moved forward but a part of his or her back above his or her breast is not varied. With this structure, the same effect of the resting posture, that is, the posture in which the back frame is reclined in a conventional seat structure, can be obtained. Since the back is not tilted backward, a leg room (footrest) space in a rear seat is not limited.

摘要： To provide A seat structure applicable to both a normal posture and a resting posture and providing a sufficiently relaxed resting posture and an excellent comfort.According to the present invention, a seat reference point adjustor for shifting a seat reference point in the resting posture anterior to a seat reference point in the normal posture is provided. With this structure, the resting posture can be taken without tilting its seat back itself backwardly. Since the seat back is not tilted backwardly, a leg room (footrest) space of a rear seat is not limited.
