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.

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.

Method for manufacturing headrest, and headrest

To obtain an integrated foam-molded product whose manufacturing cost is reduced and which makes an effective use of a property of an integration target. Foaming heat generated at the time of the foaming of a polyurethane foam raw material, whose influence has been conventionally prevented by contriving a special measure, is positively used. The integration target is influenced by foaming heat generated at the time of the foaming of the polyurethane foam raw material in a mold, to thermally deform into a desired shape along a mold shape. Consequently, it is possible to mold the integration target into an arbitrary shape in a step of integrating the integration target with a polyurethane foam layer in the mold by integrated foaming, and therefore, there is no need to work the integration target to a state closer to a final shape in a step before it is disposed in the mold, which can simplify manufacturing steps and reduce manufacturing cost.

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.

To achieve weight reduction while providing elasticity sufficient in a cushioning member for a vehicle seat, an elastic member made of expanded resin beads includes an elastic covering material having stretching properties stuck to an outer face of an expanded bead body. Therefore, when the elastic member made of expanded resin beads is bent or compressed, the respective beads themselves configuring the expanded bead body are elastically deformed according to stretching or compressing of the elastic covering material, and since the elastic deformation is not such deformation that a gap between beads of the expanded bead body largely expands, a crack occurring between beads or permanent deformation does not occur so that bending or compressing becomes possible. Accordingly, the elastic member made of expanded resin beads is suitable as a cushioning member utilizing an elastic recovering force in a bending direction and a thickness direction thereof.

There are provided a bio-signal analyzer using a sensor capable of detecting, even though it is non-invasive, a more prominent bio-signal, and a seat using the bio-signal analyzer. Air cushions (), which are sensors detecting a bio-signal in a non-invasive manner, are disposed at the positions corresponding respectively to left and right iliocostalis lumborum muscles of a person, in a substantially vertically long state along the iliocostalis lumborum muscles, with upper ends thereof being set at least at the height corresponding to a lower face of a human diaphragm. In the diaphragm, bio-signals such as heartbeats, breaths, or pulsations of aorta passing through the vicinity of the diaphragm are resonated and amplified. Further, the iliocostalis lumborum muscles are at positions where they are easily vibrated by pulsations of aorta passing through the vicinity of the lumbar region. Therefore, by disposing the air cushions () as described above, bio-signals amplified by the diaphragm and the iliocostalis lumborum muscles can be detected.

A plane magnetic sensor or a plane magnetic sensor for a multidimensional magnetic field analysis which can measure a magnetic field ever a wide area in a short time is provided. A plane magnetic sensor according to the present invention comprises a sensing layer made of a magnetoresistance effect film formed in a planar state with an arbitrary size, to pass a current therethrough due to a tunneling effect only when voltage reaches or exceeds a predetermined value, and to change its resistance value to show a giant magnetoresistance effect when directions of magnetization of magnetic fine particles change according to the strength of a magnetic field, and conductor layers laminated on respective surfaces of the magnetoresistance effect film and are made of a plurality of line conductor films formed in linear shapes along directions of the respective surfaces with predetermined intervals therebetween. The line conductor films of one conductor layer and the line conductor films of the other conductor layer are arranged to intersect to each other in plan view, with the magnetoresistance effect film therebetween.

The multi-pole magnet is separated into two pieces, and a single-pole magnet is interposed between the two pieces of the multi-pole magnet. Magnetic poles of the single-pole magnet are formed in a direction different from the direction in which those of the multi-pole magnet are formed.
