    • In a seat (10) for a motor vehicle, a seat cushion (20) is constructed by providing a cushion member (18) on a seat-section frame (14) of a seat frame (12). An upper cushion member (three-dimensional knit fabric)(86) that is a surface layer of the cushion member (18) is stretched over the seat-section frame (14) and is laid over a cloth spring member (68) that is a lower layer of the cushion member (18). When an occupant takes a seat on a cushion (20) and the cloth spring member (68) is pressed and sagged downward by a pressing force caused by the weight of the occupant seated, a tensile force of a tensile coil spring (80), or a force in a pressing direction, acts on portions of the cloth spring member (68) where the hipbone joints of the occupant seated press. Then, the tensile force of the cushion member (18) directs three-dimensional directions.
    • 在汽车座椅(10)中,座垫(20)通过在座椅框架(12)的座椅部分框架(14)上设置缓冲部件(18)而构成。 作为缓冲部件(18)的表层的上部缓冲部件(立体编织物)(86)在座位部框架(14)上延伸并覆盖布料弹簧部件(68),该布料弹簧部件 所述衬垫构件(18)的下层。 当乘坐者坐在坐垫20上并且布弹簧部件68因乘坐者的体重而产生的按压力被按压而向下方下垂时,拉伸螺旋弹簧80的拉伸力, 或按压方向的力作用于布弹簧部件(68)的就座者的髋关节的按压部位。 然后,缓冲构件(18)的拉伸力指向三维方向。
