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.
摘要翻译：座椅具有如下构造：在缓冲框架的每个侧框架中，具有沿其周边缘延伸的凸缘的内框架和外框架至少部分地彼此面对并具有间隔，并且凸缘是固定的通过折边工艺沿着其整个周边。由于整个周边边缘被卷绕，所以内框架和外框架牢固地固定。此外，由于使用了薄板状的内框架和外框架，因此可以实现每个侧框架的重量的减轻。此外，由于内框架和外框架至少部分地彼此面对，因此可以通过将膨胀的胎圈体插入到空间中来确保作为侧框架所需的压缩/拉伸强度。

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 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： 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.
摘要翻译：本发明的目的是通过使阻尼比大的反作用力较小来抑制人体的反弹。凸起部11形成在作为张力结构的座椅缓冲构件14上。该结构具有通过根据输入振动的激励力的大小由张力结构的平面波产生的变形而改变由应变能和张力的变化起作用的阻尼特性的结构。因此，由于阻尼特性对于小的励磁力的输入具有小的阻尼比功能，所以能够缓和由于座椅缓冲部件14和/或后缓冲部件24的弹簧特性引起的相位差的振动，并且通过增加应变能量和张力减小，输入大的励磁力，阻尼特性起着较大的阻尼比和较长的作业时间的作用，能够抑制人体向上的回弹。
