摘要： The object of the present invention is to suppress rebound of a human body by making a reaction force small due to a large damping ratio. A bulging portion 11 is formed at a seat cushioning member 14 which is a tension structure. This structure has a structure of changing the damping characteristics functioned by the change in strain energy and tension by deformation created by a plane wave of the tension structure in accordance with the magnitude of the excitation force of an inputted vibration. Therefore, since the damping characteristics function with a small damping ratio to an input of a small excitation force, it can relieve the vibration with a phase difference due to the spring property of the seat cushioning member 14 and/or a back cushioning member 24, and to an input of a large excitation force, by increase of the strain energy and decrease of the tension, the damping characteristics function with a large damping ratio and a long operating time, so that rebound of a human body upward can be suppressed.

摘要： A magnetic spring has at least two permanent magnets (2 and 4) spaced from each other in a kinetic mechanism. At the time of input and at the time of output, the geometric dimensions between the two permanent magnets are changed by the kinetic mechanism or an external force. The change in geometric dimensions is converted into a repulsive force in the kinetic mechanism, thereby (1) making the repulsive force from a balanced position of the two permanent magnets greater at the time of output than at the time of input, or (2) deriving a damping term of the magnetic spring to provide nonlinear damping and spring characteristics.

摘要： There is provided a bio-signal detector to detect a heart rate and a respiratory rate so that the determination of a kind of a seat load placed on a seat can be made. That is, whether the seat load is a human or an object is determined, and if it is the human, then the physique size is determined to be small or large (the level of the physique size is determined). Accordingly, as compared with the means based only on a weight of the seat load, the determination result is highly reliable. Besides, with the use of the bio-signal detector, the discrimination between the human and the object is ensured. Moreover, a structure additionally including a weight sensor allows the determination of the physique size in more accurate manner.

摘要： A structural material is provided, the strength and toughness of which are well-balanced at a high level, suitable in particular for seat frames in automobiles, aircrafts and the like. Specifically disclosed is a structural material produced by integrally joining thin steel members in a part thereof and, after joining, thermally heating a part thereof so that the heat-treated part differs from the other parts in strength and toughness. Unlike a structural material, the strength of which as a whole has been uniformly improved by heat treatment, the above-described structural material consists of a part having a high strength and a part having low strength. Thus, a structural material, the strength and toughness of which are well-balanced at a high level can be obtained. Since the strength and toughness are well-balanced at a high level, the structural material is suitable particularly for seat frames in automobiles, aircrafts and the like.

摘要： A seat has a configuration in which, in each side frame of a cushion frame, an inner frame and an outer frame which have flanges extending along peripheral edges thereof are faced to each other with a space therebetween at least partially, and the flanges are fixed by hemming process along the entire peripheral edges thereof. Since the entire peripheral edges are hemmed, the inner frame and the outer frame are securely fixed. Additionally, since the inner frame and the outer frame which are thin-plate-shaped are used, reduction in weight of each side frame can be achieved. Further, since the inner frame and the outer frame are faced to each other with a space therebetween at least partially, a compressive/tensile strength required as a side frame can be secured by inserting an expanded bead body into the space.
