Abstract
A lounger-type air manager comprises a lounger body (1) including a seat portion (2) and a backrest portion (3) provided on the rear end of the seat portion, bags (4, 5, 10) provided in the seat portion and the backrest portion and adapted to inflate and deflate when compressed air is fed thereinto and discharged therefrom, and a compressed air control device (11) for controlling the feed and discharge of the compressed air into and from the bags. The bag in the seat portion is fixed at its rear edge portion on the backrest side to the seat portion, and the bag in the backrest portion is fixed at its upper end portion to the backrest portion. The compressed air control device (50, 50', 50', 50'') changes the charging time or exhaust time for the compressed air, the capacity of each bag, or the flow resistance of a charging/exhaust pipe for each bag so as to make the bag (35, 39) among the bags, which is subjected to a heavier load from the body weight of a person seated on the lounger body (30) than the other bag (34, 36a, 36b, 37a, 37b, 38a, 38b, 41a, 41b, 42a, 42b), has the same inflation as the inflation of the other bag after the feed of the compressed air into those bags is finished.
