摘要： A vehicle seat allowing to improve a vibration absorption characteristic, securing a stable seating posture, having high vehicle operability, and allowing to alleviate fatigue due to long time seating. In a seat cushion of a vehicle seat, a first human body support portion having a center at a position corresponding to a substantially center between the pair of ischial tuberosities of a human body, and a second human body support portion corresponding to the vicinities of femoral bases of a human body and having a center at a position located forward at a horizontal distance of 100 mm along a longitudinally center line of the seat cushion from the first human body support portion are regarded respectively as spring elements, and static spring constants and dynamic spring constants thereof are set to a predetermined relationship. Thus, stability and vibration absorbency during static seating are improved.

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 includes a back part frame which is elastically deformable in a direction such that right and left side part frames are brought closer to, or moved away from, each other, and a tensile structural element which is stretched between the right and left side part frames so as to configure a backrest. Further, a headrest is provided at an upper part of the back part frame. In addition, the tensile structural element is stretched over the back part frame so as to configure a backrest, and is configured such that the back part frame is deformed so that the headrest is moved forward due to a tensile force resulting from a load imparted on the backrest.

摘要： The present invention makes it possible to easily perform judgment of a mental-and-physical state, and distinction between a person and a thing. A load body state is judged from time series data of an emphasis displacement inclination obtained by collecting displacement signal data of the load body state using a displacement signal collection sensor 10, determining a rate of change for every arbitrary interval of an original waveform as an original waveform displacement inclination at an operating unit 20, and at the same time, determining time series data of an average displacement inclination for every prescribed time period range from a plurality of original waveform displacement inclinations, and by determining an emphasis displacement inclination through slide calculation of time series data of the average displacement inclination for every prescribed sampling time. Accordingly, it is possible to obtain time series data in which wobbling-like fluctuation peculiar to a low frequency living body displacement signal is emphasized by determining an emphasis displacement inclination from an original displacement inclination and an average displacement inclination even when vibration or the like transmitted from a road surface during traveling of a car is contained in the displacement signal data collected by the displacement signal collection sensor 10.

摘要： A vehicle seat is provided with a pair of left and right seatback side frames comprising a seatback frame. The seatback frame is connected to the rear end of a seat portion frame via a reclining mechanism. The vehicle seat is further provided with a torsion bar that is an elastic body between the reclining mechanism and the seatback frame. When the seatback frame displaces and falls forward relative to the seat portion frame, the torsion bar deforms and resists the displacement of the seatback frame. The torsion bar is arranged at the upper region of the seat occupant's pelvis.

摘要： A suspension unit includes a lower frame, an upper frame vertically movably mounted on the lower frame, and two link mechanisms disposed on respective sides of the upper and lower frames for connecting them to each other. Each of the two link mechanisms includes a parallel link mechanism having two arms extending generally parallel to each other and a pantograph-shaped link mechanism having a plurality of arms. The suspension unit further includes two permanent magnets each fixedly mounted on one of the upper and lower frames with like magnetic poles opposed to each other, a metallic spring engaged with one of the pantograph-shaped link mechanisms, and a shock absorber engaged with the other of the pantograph-shaped link mechanisms that has spring properties. With such construction, vibration below a predetermined amplitude is absorbed by the spring properties of the other of the pantograph-shaped link mechanisms with the shock absorber not operated.

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.
摘要翻译：一种能够处理正常姿势和静止姿势并且在休息姿势下提供充分放松同时确保乘客舒适性极佳的座椅结构。根据本发明，后框架20本身固定到框架支撑件10，但是缓冲框架30根据乘员的运动从第一位置A移动到第二位置B，并且骨盆支撑件31的倾斜角度相应地增加。乘员的骨盆部分和比骨盆部分低的部分向前移动，但是他或她的背部在其乳房上的一部分不变。利用这种结构，可以获得与常规座椅结构中的搁置姿势相同的效果，即后框架倾斜的姿势。由于背部不向后倾斜，所以后排座椅中的腿部空间（脚踏板）空间不受限制。

摘要： In order to improve seating comfort and vibration absorbency, the present invention includes a front torsion bar unit 80 disposed in the front of a seat cushion, the front end of a base net 60 is connected to a supporting frame 84 of the front torsion bar unit 80, the rear end of the base net 60 is connected to a rear frame 70. Accordingly, owing to elastic force of a front torsion bar 81 of the front torsion bar unit 80 positioned in the front of the seat cushion, a sense of stroke at the time of seating is enhanced. A structure to dispose a torsion bar unit in the front as in the present invention works upon a tiny load fluctuation sensitively, and absorbency of high frequency vibration is further enhanced.
