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： In order to improve vibration absorbency and impact absorbency, the seat structure includes a swing member provided in a manner to be able to swing at least back and forth on a rear frame member positioned around the rear of a seat cushion, a pelvis supporting member connected to the swing member at the vicinity of the lower portion of the pelvis supporting member and disposed behind the pelvis of a seated person, and coil springs as an elastic member to support the pelvis supporting member biasing in the direction pushing forwards in a normal seating state. Accordingly, vibration inputted from the seat back side and as if patting on the back of the human body can be absorbed by the pelvis supporting member supported elastically. Besides, since the pelvis supporting member is connected to the rear frame member via the swing member, since pivoting movement in the back-and-forth direction of the pelvis supporting member is performed with a connecting portion of the swing member and the rear frame member as the center, and the radius of gyration is large, the vicinity of the lower portion of the pelvis supporting member never presses the pelvis.
摘要翻译：为了提高振动吸收性和冲击吸收性，座椅结构包括摆动构件，其以能够至少在位于座垫的后部的后框架构件上来回摆动的方式设置，骨架支撑构件连接到骨盆支撑构件的下部附近的摆动构件，并且设置在就座人的骨盆后面，螺旋弹簧作为弹性构件，以支撑骨盆支撑构件在正常就座状态下向前推动的方向。因此，从座椅靠背侧输入的振动和仿佛拍摄在人体背部的振动可以被弹性支撑的骨盆支撑构件吸收。此外，由于骨盆支撑构件经由摆动构件连接到后框架构件，因此通过摆动构件和后框架构件的连接部分进行骨盆支撑构件的前后方向的枢转运动作为中心，并且回转半径大，骨盆支撑构件的下部附近从不压迫骨盆。

摘要： A seat includes a seat cushion frame, a seat back frame mounted to the seat cushion frame, and at least one three-dimensional net having upper and lower mesh layers and a pile layer made up of a large number of piles for connecting the upper and lower mesh layers. The three-dimensional net is stretched over substantially the entire region of the seat cushion frame and the seat back frame, thereby forming a seat cushion and a seat back. The three-dimensional net has a fixed end at a front end portion of the seat cushion and another fixed end at an upper end portion of the seat back. The seat also includes a first tension member attached to the three-dimensional net at a location adjacent to a central portion thereof for imparting tension thereto, and a second tension member attached to another portion of the three-dimensional net for fastening it to at least one of the seat cushion frame and the seat back frame.

摘要： A seat structure capable of dealing with both a normal posture and a resting posture and providing sufficient relaxation in the resting posture while ensuring excellent comfortableness of an occupant.According to the present invention, a back frame 20 itself is fixed to a frame support 10 but a cushion frame 30 shifts from a first position A to a second position B according to an occupant's movement and an inclination angle of a pelvis support 31 increases accordingly. The occupant's pelvis portion and a portion lower than the pelvis portion is moved forward but a part of his or her back above his or her breast is not varied. With this structure, the same effect of the resting posture, that is, the posture in which the back frame is reclined in a conventional seat structure, can be obtained. Since the back is not tilted backward, a leg room (footrest) space in a rear seat is not limited.
摘要翻译：一种能够处理正常姿势和静止姿势并且在休息姿势下提供充分放松同时确保乘客舒适性极佳的座椅结构。根据本发明，后框架20本身固定到框架支撑件10，但是缓冲框架30根据乘员的运动从第一位置A移动到第二位置B，并且骨盆支撑件31的倾斜角度相应地增加。乘员的骨盆部分和比骨盆部分低的部分向前移动，但是他或她的背部在其乳房上的一部分不变。利用这种结构，可以获得与常规座椅结构中的搁置姿势相同的效果，即后框架倾斜的姿势。由于背部不向后倾斜，所以后排座椅中的腿部空间（脚踏板）空间不受限制。
