WIPO Patent Application WO/2017/099258
Kind Code:
A1
Abstract:
In the present invention, a fabric member (4) bridging the front and the rear of a cushion frame (20) is supported by fabric member supporting units (200, 200) provided on the front part and the rear part of the cushion frame (20). The fabric member supporting units (200, 200) are bridged and unitized by a torsion bar (220) bridging a pair of end support members (210, 210) and a plurality of engaging rods (230) such that the fabric member supporting units (200, 200) have a high stiffness in the lateral direction and have less distortion due to a human weight, a support load variation accompanying seating actions, and a load variation due to input vibrations etc. As such, the present invention achieves a preset and expected vibration absorption property or the like more reliably compared with the conventional art.
