摘要： An upper end portion of a seat backrest and a lower end portion of a head rest are superposed together. A rear end portion of an upper portion cushion member and a lower end portion of the seat backrest are superposed together. These superposed portions are sewn together by thin threads which break when pressing force of a predetermined value or greater is applied to the seat backrest. Thus, when pressing force of the predetermined value or greater is applied to the seat backrest, the thin threads break. A portion of the seat backrest which a shoulder portion of a seated occupant contacts, and a portion of the seat backrest which buttocks of the seated occupant contact, are enlarged, and impact force can be damped.

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.
摘要翻译：座椅包括座椅框架和由座椅框架支撑的缓冲材料，并且具有三维针织物，该三维针织织物通过与连接螺纹连接而形成，所述三维针织织物布置成与一个针织物分离另一个。衬垫材料包括当乘员坐在座椅上时将反作用力施加到衬垫材料的延伸侧时的弹性柔量的第一区域基本上等于乘坐人体的一部分按压衬垫材料的弹性柔量以及弹性柔量大于第一区域的第二区域。因此，可以提供薄而轻的座椅，能够减轻长时间坐着时对乘员的块茎尾部的负荷集中，能够提高振动传递特性。

摘要： A seat provides a band-like support for the body sides of a user so as to reduce the supporting pressure on the user's lumbar and to hold the user's upper body stably. In this seat, the center of a load to be received in regions symmetrically divided to a vertical central line of the seat are positioned outside of a back region defined by left and right angulus inferior scapulae and by the upper ends of iliac bones. Moreover, the load ratios in the individual regions are not more than 25% in the region corresponding to a region extended downward from the back region.

摘要： A seat structure includes a torsion bar 40 disposed along the width direction in the vicinity of the bottom end of a back frame 20, a pelvis supporting plate 50 is connected to the torsion bar 40, and a flat-type supporting member 60 for the seat back is engaged with the vicinity of the bottom end of the pelvis supporting plate 50 and strained. Slack of the flat-type supporting member 60 can be eliminated by the pelvis supporting plate 50 to enhance the appearance. Further, a vibration inputted from the seat back side, and vibrates as if patting on the back of the human body can be absorbed by an elastic force of the torsion bar 40.

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： 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.
