摘要： A vehicle seat is provided with a pair of left and right seatback side frames comprising a seatback frame. The seatback frame is connected to the rear end of a seat portion frame via a reclining mechanism. The vehicle seat is further provided with a torsion bar that is an elastic body between the reclining mechanism and the seatback frame. When the seatback frame displaces and falls forward relative to the seat portion frame, the torsion bar deforms and resists the displacement of the seatback frame. The torsion bar is arranged at the upper region of the seat occupant's pelvis.

摘要： A seat includes a back part frame which is elastically deformable in a direction such that right and left side part frames are brought closer to, or moved away from, each other, and a tensile structural element which is stretched between the right and left side part frames so as to configure a backrest. Further, a headrest is provided at an upper part of the back part frame. In addition, the tensile structural element is stretched over the back part frame so as to configure a backrest, and is configured such that the back part frame is deformed so that the headrest is moved forward due to a tensile force resulting from a load imparted on the backrest.

摘要： In order to improve seating comfort and vibration absorbency, a structure including a first torsion bar unit 70 disposed in the rear of a seat cushion, and a second torsion bar unit 80 disposed in the front of the seat cushion, and a base net 60 stretched between a rear supporting frame 74 of the first torsion bar unit 70 and a front supporting frame 84 of the second torsion bar unit 80, is provided. Owing to the elastic force of a front torsion bar 81 of the second torsion bar unit 80 positioned in the front of the seat, a sense of stroke at the time of seating is enhanced. Owing to the elastic force of a rear torsion bar 71 of the first torsion bar unit 70 positioned in the rear of the seat, similarly to the conventional structure, a load of a seated person can be sufficiently received and a stable seating comfort can be obtained. Since both the first torsion bar unit 70 and the second torsion bar unit 80work together to vibration inputted during driving, vibration absorbency is more enhanced than ever.
摘要翻译：为了提高座椅舒适性和振动吸收性，包括设置在座垫的后部的第一扭杆单元70和设置在座垫前部的第二扭力杆单元80和延伸的基座60的结构设置在第一扭杆单元70的后支撑框架74和第二扭力杆单元80的前支撑框架84之间。由于位于座椅前部的第二扭力杆单元80的前扭杆81的弹力增加了就座时的行程感。由于位于座椅后部的第一扭力杆单元70的后扭杆71的弹性力与常规结构类似，可以充分地接收就座者的负载并且可以获得稳定的就座舒适度。由于第一扭力杆单元70和第二扭力杆单元80两者共同作用于驱动期间输入的振动，因此吸振性比以往任何时候都更强。

摘要： The structure is formed by serially connecting a torsion bar and a coil spring via a arm and a supporting frame to thereby elastically support a flat-type supporting member, and by disposing a cushioning member for seat cushion provided with a spring characteristic closely analogous to a load-to-deflection characteristic (spring characteristic) of the muscle of a human body above the flat-type supporting member. Accordingly, it is possible to make a spring characteristic for working when supporting a load of a human different from a spring characteristic for working when removing vibration even with an extremely simple structure. In other words, the structure has an excellent function to make the spring constant at work when removing vibration, especially when removing a high frequency component.

摘要： The object of the present invention is to suppress rebound of a human body when receiving a large impact load accompanying a collision or the like. A back frame member 20 and a seat frame member 10 are individually formed by welding or caulking, and a link member 30 for connecting both is attached to the back frame member 20 and the seat frame member 10 by welding or caulking. Each of the frame members is provided with a cushioning member as a tension structure. Upon receipt of an impact vibration or an impact force at a predetermined magnitude or more, the tension of the cushioning member provided as the tension structure lowers to be able to exhibit high damping characteristics.

摘要： The object of the present invention is to improve the production efficiency by making its bonding process unnecessary to simplify the production process. The method of production comprises the step of integrally incorporating a magnetic material when the stationary holders 21 and 22 of the stationary member and the movable holder 31 of the movable member 30 are molded with a non-magnetic material such as a plastic material and the like. Therefore, a magnet unit in which the stationary magnets 23 and 24 or the movable magnet 32 is integrally incorporated into the stationary holders 21 and 22 or the movable holder 31 can be provided only by giving magnetization treatment on the magnetic material without using a bonding process.

摘要： A vibration generating mechanism includes first and second permanent magnets spaced from each other with the same magnetic poles opposed to each other, and an electromotive actuator for driving the first permanent magnet. The electromotive actuator moves the first permanent magnet periodically and reciprocatingly relative to the second permanent magnet to change the opposing area of the first and second permanent magnets thereby causing the second permanent magnet to vibrate relative to the first permanent magnet.
