| Abstract: |
These amusement devices enable users to experience the sensations of zero gravity or weightlessness in free flight, with the sensations heightened because the users experience gravity forces in excess of one while being accelerated into and retrieved from free flight. The apparatus comprises coordinated, cooperating acceleration and retrieval means. The flight may be essentially vertical or have a parabolic trajectory. Use of the apparatus is not dependent on the physical condition and ability of users.

What is claimed is:
1. An energy absorbing bed, having a working surface and comprising a support structure, a plurality of elongated, resilient members having first and second ends and longitudinal axes, said members being positioned adjacently within said support structure with said longitudinal axes oriented essentially normal to said working surface, said working surface comprising said first ends, said bed including a plenum chamber within said support structure and means for supplying air at pressure connected to said plenum and in which said members are made from thin, flexible material, said first ends are closed and said second ends are open and with said second ends in communication with said plenum chamber so that said members can be inflated with air supplied to said plenum chamber by said means for supplying air, and wherein said support structure comprises an essentially cylindrical sidewall having a bottom edge, an essentially circular bottom having an outer edge, a plurality of tension ties, said second ends of said members having edges, said sidewall being flexible and impermeable, and said bottom being impermeable, said bottom edge being sealed to said outer edge, said edges of said second ends being attached to said bottom by said tension ties, said edges of said second ends of adjacently positioned said members being sealed to adjacent edges and to said sidewall to form said plenum chamber.
