摘要： To make it possible to improve seated person's posture stability with respect to input vibration, and more improve a vibration absorption characteristic or an impact absorption characteristic caused by impact vibration as compared with conventional ones. A suspension mechanism 1 has a structure in which two suspension units 100, 200 which support a movable support part 140 and a seat support part 240 through link mechanisms 110, 120 respectively are arranged in two upper and lower stages, and a configuration such that, when the movable support part 140 and the seat support part 240 move up and down relatively in response to input vibration, the two link mechanisms 110, 210 supporting the respective parts are operated to rotate in opposite directions to each other. Therefore, a position of a hip point of a person seated on a seat supported by the seat support part 240 is displaced in an approximately vertical trajectory, which reduces forward and backward swinging and stabilizes a seating posture, resulting in good ride comfort, as compared with a case of one link mechanism.

摘要： To provide a power seat slide device having improved effects of reducing abnormal sound, a temperature increase, and so on in gear mechanisms and so on. Gear mechanisms 30 each include a case 310 in which a worm 320 and a worm wheel 330 are rotatably supported, the cases 310 are suspended from and supported by upper rails 12. The worms 320 are connected to and supported by a rotational force transmission shaft 220 of a drive mechanism 20, and the worm wheels 330 are screwed to and supported by slide screws 11a provided in lower rails 11. Further, the cases 310 are supported on the lower rails 11 via balls 340 which are rolling members. This structure stabilizes a slide operation of the cases 310 themselves and can further improve the effects of reducing abnormal sound and so on.

摘要： 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. Since a moving magnet unit 52 is provided such that a moving direction of a moving body coincides with an approximately perpendicular direction to a mutual displacement direction of an upper frame 10 relative to a lower frame 20, the thickness (height) of a fixed magnet unit 51 is made thin as compared with a case where the moving magnet unit is provided such that the moving direction of the moving body coincides with approximately the same direction as the mutual displacement direction of the upper frame relative to the lower frame, so that the thickness of the whole seat suspension at a position at which the upper frame 10 has come closest to the lower frame 20 (a lower limit position) can be made thin.

摘要： In order to improve posture supportiveness, body pressure dispersiveness, energy absorbency, and the like, a base net (170) for a back is formed from a three-dimensional stereoscopic knit, and has a configuration in which seams (171a-171d) for bringing a pair of ground knitted fabrics thereof to close to each other in a thickness direction are partially provided, predetermined preliminary compression is applied in the thickness direction by the seams, and thereby residual stress is generated in a surface direction (stretching direction). Therefore, stiffness is partially increased by partial improvement in residual stress, and consequently a human body with extreme roughness is supported by nearly uniform pressure. Thus, in spite of a simple configuration in which the seams (171a-171d) are provided in desired regions, posture supportiveness and body pressure dispersiveness can be improved. Further, by arbitrarily adjusting the formation positions of the seams (171a-171d), the pressure distribution is adjusted, thereby making it possible to easily control the vibration mode to desired setting, and easily improve vibration absorbency.

摘要： A neck injury is improved with a structure having a lifting mechanism part only on one side. While a lifting driving part (160) is provided on a side of one side frame (11), a coupling driving rod (170) is coupled to a rotation center of a drive gear (160d), a driving link (171) is disposed on a side of the other side frame (11), and the driving link (171) is coupled to the coupling driving rod (170). A driving force in the lifting driving part (160) operates on the side of one side frame (11) having the drive gear (160d), but on the side of the other side frame (11), the driving link (171) rotates together with the drive gear (160d) via the coupling driving rod (170), so as to perform a lifting or lowering operation. The shape of a virtual square coupling contact points of the driving link (171), the side connectors (153, 153), the coupling driving rod (170), and the drive gear (160d) does not collapse, and thus an external input is dispersed.

摘要： A technology to grasp a state of a human being more accurately is provided. The technology is provided with means for acquiring a time-series waveform of a frequency from a time-series waveform of a biological signal sampled from the upper body of a human being and for further acquiring a time-series waveform of frequency slope and a time-series waveform of frequency fluctuation and for applying frequency analysis to them. In the frequency analysis, a power spectrum of each frequency corresponding to a functional adjustment signal, a fatigue reception signal, and an activity adjustment signal, respectively, determined in advance is acquired. Then, a state of a human being is determined from a time-series change of each power spectrum. The fatigue reception signal indicates a degree of progress of fatigue in a usual active state and thus, by comparing it with degrees of predominance of the functional adjustment signal and the activity adjustment signal as their distribution rates, a state of a human being (relaxed state, fatigued state, state in which sympathetic nerve is predominant, a state in which parasympathetic nerve is predominant and the like) can be determined more accurately.
