ABSTRACT:
An air bag large enough for several children to jump on at one time is equipped with one or more bellows centrally on the top surface providing means for children safely to propel one another for great vertical distances, being assured of cushioning of the fall when they return by the perimeter of the bag. Preferably the bag is of the constant-volume or non-stretching type so that jump-on compression of any portion of the bag results not in stretching the bag but instead efficiently snaps the bellows structure out to the full extent, and upon relaxation permits the bellows structure to collapse instead of remaining distended.
Similarly the bellows structure is preferably of the non-stretch material and preferably has a top reinforcement and an elastic return which may be a spring.
