SEAT

摘要

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.
