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 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 cushion of a vehicle seat has a base seat whose front end is anchored to a front frame of a frame for a sitting portion, and whose rear end is connected to a rear frame of the frame for a sitting portion via helical tension springs. A supporter, supported via helical tension springs at a pair of left and right side frames of the frame for a sitting portion, is disposed at a lower side of the base seat so as to support a femoral region of a seated person. The supporter and the helical tension springs structure an auxiliary vibration system whose mass element is a femoral region of a seated person. The auxiliary vibration system is made to function as a dynamic vibration absorber with respect to up-down vibrations of a main vibration system whose mass element is an upper body of a seated person.

摘要： A seat includes a seat frame, and a cushion material supported by the seat frame and having a three-dimensional knitted fabric which is formed by joining, with connecting threads, a pair of ground knit fabrics which are disposed so as to be separated from one another. The cushion material includes a first region whose elastic compliance when a reaction force is applied to an extending side of the cushion material when an occupant is seated on the seat is substantially equivalent to an elastic compliance of a portion of the occupant's body pressing the cushion material and a second region whose elastic compliance is larger than that of the first region. Accordingly, a thin and light seat can be provided, load concentration on the occupant's tuber ishiadicum bottom portion when seated for a long period of time can be mitigated, and vibration-transmitting characteristics can be improved.

摘要： In order to improve vibration absorbency and impact absorbency, the seat structure includes a swing member provided in a manner to be able to swing at least back and forth on a rear frame member positioned around the rear of a seat cushion, a pelvis supporting member connected to the swing member at the vicinity of the lower portion of the pelvis supporting member and disposed behind the pelvis of a seated person, and coil springs as an elastic member to support the pelvis supporting member biasing in the direction pushing forwards in a normal seating state. Accordingly, vibration inputted from the seat back side and as if patting on the back of the human body can be absorbed by the pelvis supporting member supported elastically. Besides, since the pelvis supporting member is connected to the rear frame member via the swing member, since pivoting movement in the back-and-forth direction of the pelvis supporting member is performed with a connecting portion of the swing member and the rear frame member as the center, and the radius of gyration is large, the vicinity of the lower portion of the pelvis supporting member never presses the pelvis.
