摘要： A biological signal detection device is capable of accurately and simply measuring biological signals and promotes daily health care. A body abutting-side cushioning member 10 formed of a three-dimensional knitted fabric is substantially circular in plan view. A base cushioning member 20 is also substantially circular in plan view. A square one tends to undergo deformation such as turning-up or folding of its edges around the corners when, for example, a person sits thereon. Such deformation tends to distort detection data. Moreover, the folding and the like give a feeling of something foreign. In contrast, a substantially circular one less undergoes such folding and the like.

摘要： A novel technique for analyzing a biological state is provided. A body trunk biological signal (aortic pulse wave) extracted from the back of a body trunk is differentiated twice. By using a resultant second derivative waveform, a waveform component of a maximum amplitude of a low frequency appearing as a result of switch of an amplitude from attenuation to amplification in transition from a contracting phase to a diastolic phase of a ventricle is specified in each period of the second derivative waveform. Inflection points are specified that appear before and after the maximum amplitude waveform component. A biological state is analyzed using information about each of the inflection points. The two inflection points obtained from a reference form of the second derivative waveform of the aortic pulse wave substantially agree in time phase with first heart sound and second heart sound (or an R wave and a T wave in an electrocardiogram) indicating the dynamic state of a cardiovascular system. This enables analysis of a biological state.

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 each include a case in which a worm and a worm wheel are rotatably supported, the cases are suspended from and supported by upper rails. The worms are connected to and supported by a rotational force transmission shaft of a drive mechanism, and the worm wheels are screwed to and supported by slide screws provided in lower rails. Further, the cases are supported on the lower rails via balls which are rolling members. This structure stabilizes a slide operation of the cases themselves and can further improve the effects of reducing abnormal sound and so on.

摘要： A headrest in which a pad layer is integrally formed, including a portion with a narrow gap, between a mechanism having various types of incorporated functions and a skin member. A shock absorbing member that is an injection-passage-forming member having a foaming raw material injection passage formed so as to run substantially along a direction that is the vertical direction of the headrest in orientation of when a seat is attached, is set in the inside of a skin member, and a foaming raw material for forming the pad layer is injected through the foaming raw material injection passage. The configuration preferably causes the foaming raw material to spread by the foaming start time, as the foaming raw material spreads to the outer side of the headrest, that is, to the inner surface of the skin member, where the pad layer is required to be formed.

摘要： A seat structure. A reinforcing structure in a substantially rectangular frame shape is set in an area where cushion-part side frames and back-part side frames are coupled to each other via reclining mechanism parts, from vicinities of rear portions of the cushion-part side frames up to vicinities of lower portions of the back-part side frames. The reinforcing structure increases unity of a cushion frame and a back frame, and when a load is applied to the back frame due to an impact at the time of a rear-end collision or the like, the load acts as a force deforming mainly the cushion frame via the reinforcing structure, and when the body of a seated person thereafter moves rearward, the load acts as a force deforming mainly the back frame, making it possible to use not only strength of the back frame but also strength of the cushion frame.

摘要： A surface fastener formed of a synthetic resin and in which a base with a 0.1 to 0.9 mm thickness and engagement element groups including engagement elements with a 0.2 to 0.8 mm protrusion height are integrally molded, and engagement element rows are composed of the plural engagement elements arranged in a row direction and each protruding independently. A cushioning member is covered with a covering member via the surface fastener. A resistance value of the surface fastener by itself as measured by a handle-o-meter method conforming to the JIS L 1096 E method is 80 to 150 g, whereas a load-deflection characteristic when a pressure is applied to an overlapping portion of the stacked surface fastener and cushioning member by a pressure plate with a 30 mm diameter approximates a similarly measured load-deflection characteristic of the cushioning member by itself.

摘要： A seat suspension with a compact structure while being capable of coping with input vibrations not only in a vertical direction but in six-axis directions. Three pantograph links between a vehicle body floor side and a seat side are employed. Thus, control in six-axis directions is possible, allowing simplification compared to conventional structures. In addition to an active control mechanism using the pantograph links, the seat suspension has a compressed coil spring and the magnetic spring as a first elastic member and a second elastic member. Specifically, damping is performed with high efficiency by controlling the seat side in a reverse phase to the vehicle body floor side with respect to the input direction of vibrations by the active control mechanism and meanwhile performing damping passively by these elastic members.
