Breathable seat

摘要

A breathable seat (S1) comprises a seat body (1) formed of urethane foam (1a), a three-dimensional network cushion body (2) incorporated in that region of the seat body (1) which bears a user's body, a seat cover (4) having breathability, and a pan frame (5). The cushion body (2) is formed of a large number of continuous linear elements (2a) of thermoplastic resin. The linear elements (2a) are looped windingly so that their respective contact portions are fused together. The seat body (1) is formed having venting holes (3) that penetrate the urethane foam (1a) in its thickness direction. The venting holes (3) communicate with the cushion body (2) and apertures (5a) of the pan frame (5). The seat cover (4) envelops the seat body (1) and the cushion body (2).
