Abstract
In order to improve seating comfort and vibration absorbency, the present invention includes a front torsion bar unitdisposed in the front of a seat cushion, the front end of a base netis connected to a supporting frameof the front torsion bar unit, the rear end of the base netis connected to a rear frame. Accordingly, owing to elastic force of a front torsion barof the front torsion bar unitpositioned in the front of the seat cushion, a sense of stroke at the time of seating is enhanced. A structure to dispose a torsion bar unit in the front as in the present invention works upon a tiny load fluctuation sensitively, and absorbency of high frequency vibration is further enhanced.
