  • Referring now in detail to the drawing, the reference numeral 20 denotes generally a passive exercise cushion in accordance with this invention. The cushion 20 as illustrated in the embodiment shown in FIGS. 2-4, includes three interdependent, air inflatable, components--a back cradling pillow member 22, a pressure pouch 24, and a support mat 26. The aforementioned components are encased within a fabric cover 28.

    A portable, inflatable exercise cushion made from welded PVC plastic, divided into two compartments with a centre weld through which a small air passage allows only restricted air transfer.

  • As previously discussed, a counterbalancing force will be exerted by the parallel abdominal muscles and related sets of back muscles which support the spine, such as the erector spinea, the rectus abdominus, the lateral muscles, the hip flexor muscles and the gluteal muscles. The stretching and contraction of these muscles are indicated generally by the several arrows designated as 72 and this will occur as a natural reaction to the forwardly directed force 70. It is, however, within the scope of this exercise cushion to develop active exercises directed to one or more muscle groups, which can be achieved, for example, by moving the neck, elevating the leg, raising and lowering the arms and by turning the head.
