<p>A seat comprising a seat frame,and a cushion material including a three−dimensional knitted fabric formed by joining a pair of ground knitted fabrics spaced apart from each other through a joining yarn and supported by the seat frame.As elastic compliance characteristics when an elongation side reaction acts at the time of seating,the cushion material includes a first part having an elastic compliance substantially equal to that at a pressing human body part,and a second part having an elastic compliance higher than that at the first part.A thin lightweight seat can thereby be provided,comfortableness is improved by relaxing concentration of load beneath the tuber of ischium,occurrence of numbness is reduced after long time seating and transmission characteristics of vibration can be enhanced.</p> |
