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： A damper has a simple structure yet exhibits appropriate damping force according to a relative displacement amount. The damper includes: a line-shaped member 32 wound around an outer peripheral surface of a piston 3 which makes a relative motion in a cylinder 2; and a viscous fluid which is made to adhere to the line-shaped member 32 and exhibits viscous damping force. The relative motion of the cylinder 2 and the piston 3 produces tension, and in the line-shaped member 32, as an amplitude is smaller, its contiguously wound portions each try to deform so as to twist along a circumferential direction of the line-shaped member 32 itself, and as the amplitude is larger, the contiguously wound portions more tend to try to deform as a unit. When the amplitude is small, frictional resistance decreases, resulting in the smooth motion of the piston 3, and appropriate damping force is obtained due to the viscous damping force of the viscous fluid. When the amplitude is large, as a result of the increased tendency that the contiguously wound portions of the line-shaped member 32 try to deform as a unit, friction damping force acts relatively greatly.

摘要： A biological signal with small amplitude is detected with greater sensitivity than before. A mechanical amplification device provided with a three-dimensional knitted material 10 and plate-shaped foam bodies 21 and 22 laminated in the periphery of the three-dimensional knitted material, preferably a mechanical amplification device provided with a film 16 disposed between the three-dimensional knitted material 10 and the plate-shaped foam bodies 21 and 22 is provided, and a vibration sensor 30 is attached to this mechanical amplification device. Micro vibration on the body surface caused by a human biological signal such as heart rate, respiration, atrial and aortic vibrations and the like is propagated to the plate-shaped foam bodies 21 and 22, the film 16, and the three-dimensional knitted material 10, and membrane vibration is generated in the plate-shaped foam bodies 21 and 22 and the film 16, while string vibration of a fiber is generated in the three-dimensional knitted material 10. As a result, the biological signal such as heart rate, respiration, atrial and aortic vibrations and the like can be accurately transmitted.

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： Provided is a technique for more accurately ascertaining a person's status. In particular, the present invention makes it possible to accurately ascertain the detection of alcohol or the like. A fluctuation waveform of an ultra-low-frequency band is found from a biosignal collected from a biosignal measuring means, the fluctuation waveform is plotted as coordinate points on a four-quadrant coordinate system on the basis of a predetermined standard, and biological status is estimated on the basis of temporal change in the coordinate points. According to the method of the present invention for plotting a fluctuation waveform as coordinate points on a four-quadrant coordinate system on the basis of the predetermined standard, change in the fluctuation waveform of the ultra-low-frequency band can be expanded or highlighted and thus perceived, and therefore the present invention is adapted for more accurately perceiving change in a person's status.

摘要： Weight reduction is realized and vibration absorbability and impact absorbing properties are improved. A vehicle seat 1 of the present invention includes a tension structure extended on a back frame 10 and has a configuration in which a natural frequency in the right-and-left direction of the back frame 10 is set lower than the natural frequency in the front-and-rear direction. Since the natural frequency in the right-and-left direction is lower than the natural frequency in the front-and-rear direction, 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： 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.
