IPC: A47C31/11
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To provide a seat capable of reducing the recovering cost of the outermost layer and retaining the adhesive performance of the outermost layer even if it is repeatedly recovered. SOLUTION: Since a hook and loop male faster 2b is fixed to a cushion body 2 side, even when the outermost cover 3 is recovered, the hook and loop male fastener 2b which is several times as expensive as the hook and loop female fastener 3b can be reused as it is at the obverse of the cushion body 2. Hence, the recovering cost of the outermost cover 3 can be greatly reduced as compared with the case that the male fastener 2b is fixed to the outermost cover 3 side. Further, when the outermost cover 3 is repeatedly replaced several times, the female fastener 3b is worn and damaged, but as it is fixed to the outermost cover 3 side, it can be replaced with a new one together with the outermost cover 3. Therefore, the adhesive performance of the outermost cover 3 can be kept.
