Automotive seat

A seat structure includes a torsion bardisposed along the width direction, and an armwhich is connected to the torsion bar, enforced in the direction of falling backward at a normal state by the torsion barin the rear of a seat cushion, and disposed is a flat-type supporting memberbetween the supporting framesupported by the armand a frame member provided in front of the seat cushion, being strained by the elastic force of the torsion bar. Through this structure, the spring characteristic to give an influence on comfortability and riding comfort at the time of being seated can be given by the torsion bar, so that the number of coil springs which have been necessary in the vicinity of the body side can be reduced or the use of the coil spring can be stopped.

Seat structure

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.
