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： A cushion member includes an intermediate layer, and an upper layer and lower layer stacked and fixed thereto. The cushion member is fixed to a frame by bending an end part of the cushion member so that the upper layer comes to the front side and the lower layer comes to the back side. The intermediate layer is subjected to shear force and the upper layer and the lower layer are subjected to compressive and tensile stress. With the spring characteristic of the intermediate layer, residual stress of the tension and compression is applied to the upper and lower layers from the intermediate layer. Thus, the cushion member can have a restoring property, generation of creases during no load application can be reduced, permanent setting is made less likely, and a compression characteristic in the thickness direction is increased.
摘要翻译：缓冲构件包括中间层，以及堆叠并固定在其上的上层和下层。缓冲构件通过弯曲缓冲构件的端部而固定到框架，使得上层进入前侧，下层到达后侧。中间层承受剪切力，上层和下层受到压缩和拉伸应力。随着中间层的弹簧特性，拉伸和压缩的残余应力从中间层施加到上层和下层。因此，缓冲构件可以具有恢复特性，可以减少无负荷施加期间的折痕的产生，使永久性设定变得不太可能，并且厚度方向上的压缩特性增加。

摘要： 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.

摘要： A vehicle seat includes a tension structure extended on a back frame with a configuration in which a natural frequency in the right-and-left direction of the back frame is set lower than the natural frequency in the front-and-rear direction. Thereby, the structure can easily deflect in the right-and-left direction. Therefore, since an impact load larger than a predetermined level inputted in the front-and-rear direction due to front-and-rear/pitching vibration or a rear collision and the like becomes a force of deflecting the back frame in the right-and-left direction, the vibration/impact energy is consumed by that, and moreover, rearward displacement of the back frame consumes vibration/impact energy. Thus, absorbing performances of the vibration/impact energy are higher than before.
摘要翻译：车辆座椅包括在后框架上延伸的张力结构，其中后框架的左右方向上的固有频率被设定为低于前后方向的固有频率。因此，该结构可以容易地在左右方向上偏转。因此，由于由于前后方向/俯仰振动或后方碰撞等而在前后方向上输入的冲击载荷大于其右侧和右侧的偏转力左右方向，振动/冲击能量被消耗，此外，后框架的向后位移消耗振动/冲击能量。因此，振动/冲击能量的吸收性能比以前更高。

摘要： Follow-up performance to respiratory movements is made higher than that of the prior art without obstructing movements of the pelvis of a person. A configuration is adopted that a cushioning member arrangement frame for a seat back 34, 140 and a cushioning member arrangement frame for a seat cushion are displaced according to load fluctuation to a cushioning member for a seat back 40, 150 or a cushioning member for a seat cushion 20. That is, such a configuration is adopted that the cushioning member arrangement frame for a seat back 34, 140 or the cushioning member for a seat cushion 20 not only moves according to load fluctuation but also frames themselves supporting them move via tension structure members spread over the frames (a cushioning member for a seat back and a cushioning member for a seat cushion). Accordingly, when a person lays his/her pelvis at his/her sitting position for deep breathing, the cushioning member arrangement frame for a seat back is displaced to push the vicinity of an upper portion of the cushioning member for a seat back, so that the vicinity of a lower portion of the cushioning member for a seat back is pushed forward to enrich support of the sacrum of the person.
