发明名称 Passive ergonomic work chair
摘要 A personal office or work chair is provided which includes an open frame construction wherein a seat portion of the chair includes a pair of front springs mounted on either side of the frame, each spring located between frame members extending rearwardly toward the chair seat back portion of the chair, and forwardly to the front edge of the seat portion. In a preferred arrangement, each spring comprises a strip of non-woven fiberglass epoxy resin including forward and rearward substantially planar mounting portions. At the same time, the seat back portion of the chair includes an open frame wherein a pair of laterally spaced frame members are hingedly secured to the corresponding laterally spaced frame members of the seat portion by a hinge bar or rod extending across the frame. One each side of the frame, there is a relatively rigid but somewhat flexible plastic spring fixedly secured between adjacent seat frame and seat back frame members, overlapping the hinged connection between the seat and seat back frame portions. These relatively rigid plastic springs are generally L-shaped and are fixedly riveted to the seat frame members.
