摘要 |
A pneumatic massage mat comprises a plurality of juxtaposed air chambers which are expanded and contracted in given sequence by sequentially feeding and bleeding air under pressure into and out of the respective chambers. The air space of each said air chamber is narrowed in the width direction at a substantially central portion and opposed end portions with respect to the longitudinal direction of the chamber such that these narrow portions are filled with a smaller volume of air than the remaining portions.
