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.

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 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： 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 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。
