Abstract: 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.

Abstract: There is provided a touch fastener that has high followability to the relative movement of portions to be engaged and does not easily separate from a mating member, and thus is usable in a wider range of applications. In the touch fastener, all the elements, that is, first strands, second strands, and engagement elements are formed of a thermoplastic elastomer. Further, the plurality of first strands and the plurality of second strands are disposed to intersect with each other, and consequently, hole portions each surrounded by the two adjacent first strands and the two adjacent second strands are provided. Accordingly, it has a high elastic function, easily stretches, and has high followability to the relative movement of portions to be engaged.

Abstract: A mesh hook surface fastener does not lose engagement ability even when subjected to mold-in forming and gives only a slight feeling of something foreign. The mesh hook surface fastener contains first shape holding ribs (a21) with a relatively small protrusion height and second shape holding ribs (a22) with a relatively large protrusion height which protrude to the opposite side of hook-shaped engagement elements (B1, B2) across a base layer (A1) and are alternately arranged. The heights of the adjacent shape holding ribs (a21, a22) are different, which prevents the direct entrance of a foamable resin liquid and weakens its force. As the force weakens, foaming and curing progress more readily and, as a result, the amount of the foamable resin liquid that passes through meshes of the base layer to reach the hook-shaped engagement elements can be reduced.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A predetermined component such as a recliner is attached to a long member in advance, and thereafter by bending the long member, a pair of side frames and an upper frame are integrally formed. Therefore, the recliner can be attached to the long member not bent yet and thus in a substantially flat state, and in addition, the pair of side frames and the upper frame can be integrally formed, which does not require labor and contributes to a reduction in manufacturing cost. Moreover, by adjusting a position where the bending is performed, it is possible to manufacture seat frame structures different in dimension even if the long members not bent yet have the same length, and from this viewpoint as well, it is possible to reduce labor and manufacturing cost.
