摘要： To promote bloodstream and reduce fatigue, a seat structure makes a slight sitting posture change by adding a minute body motion with no necessity of moving a cushion frame or a seat frame although it realizes a supporting pressure change at a wide area, not locally, in a seat cushion or a seat back. The seat structure includes a cushioning member for a seat cushion stretched across the cushion frame, and a cushioning member for a seat back stretched across the back frame. The seat structure includes: a lower cloth spring of a seat cushion or a cloth spring of a seat back stretched across the cushion frame or the back frame via a torsion bar; and a cloth spring adjusting member to change a supporting pressure by both cushioning members by adjusting tension of the lower cloth spring or the cloth spring.

A mechanical amplification device provided with a film is disposed between the three-dimensional knitted material and the foam bodies and is provided, and a vibration sensor is attached to this mechanical amplification device. Micro vibration on the body surface caused by a human biological signal is propagated to the foam bodies, the film, and the three-dimensional knitted material, and membrane vibration is generated in the foam bodies and the film, while string vibration of a fiber is generated in the three-dimensional knitted material. As a result, the biological signal such as heart rate, respiration, atrial and aortic vibrations and the like can be accurately transmitted.

摘要： A cushion member includes an intermediate layer, and an upper layer and lower layer stacked and fixed thereto. The cushion member is fixed to a frame by bending an end part of the cushion member so that the upper layer comes to the front side and the lower layer comes to the back side. The intermediate layer is subjected to shear force and the upper layer and the lower layer are subjected to compressive and tensile stress. With the spring characteristic of the intermediate layer, residual stress of the tension and compression is applied to the upper and lower layers from the intermediate layer. Thus, the cushion member can have a restoring property, generation of creases during no load application can be reduced, permanent setting is made less likely, and a compression characteristic in the thickness direction is increased.

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： A seat provides a band-like support for the body sides of a user so as to reduce the supporting pressure on the user's lumbar and to hold the user's upper body stably. In this seat, the center of a load to be received in regions symmetrically divided to a vertical central line of the seat are positioned outside of a back region defined by left and right angulus inferior scapulae and by the upper ends of iliac bones. Moreover, the load ratios in the individual regions are not more than 25% in the region corresponding to a region extended downward from the back region.

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.
