Abstract
The present invention relates to a cushion device utilized for a bed, sofa, chair, or seat for a vehicle. The cushion device comprises an outer supporting member (20) having a shock absorbing space (10) and a cushion plate (30) to be elastically installed on the outer supporting member (20). The cushion device of the present invention comfortably accommodates a human body, and has long life.
Claims19
A cushion device, the device comprising:
- an outer supporting member (20), having a predetermined area which is formed to include a shock absorbing space (10);
- a cushion plate (30) which includes two bars (31,31') that are located at a predetermined interval inside from said outer supporting member (20) and connected to said outer supporting member (20) by a plurality of elastic springs (40) and a plurality of steel wires (32) that are installed at regular intervals between said two bars;
- and
- at least one elongated element (33), each elongated element (33) having two ends, the two ends being connected to said outer supporting member (20) by elastic springs (50), and each elongated element (33) being parallel to a longitudinal axis of the outer supporting member (20) and arranged transversely to said plurality of said steel wires (32) to support said steel wires (32), wherein said plurality of said steel wires (32) are tied by strings (34) made of nonmetal materials on said at least one elongated element (33).
