Abstract: A height-adjustable seal frame structure for a DAP exercise system has a seal frame, opposing lateral vertical lifts, and opposing lateral tensile restraints. The seal frame defines opposing lateral side restraint connectors and can be attached to an inflatable enclosure top portion about a user port. The vertical lifts can be attached at lateral sides of the system and a longitudinal position proximate the user port for vertically driving a carriage to adjust height. The first end each tensile restraint can securely attach to a lift carriage connector and the second end can securely attach to the corresponding restraint connector at a restraint length therebetween. In use, the seal frame can be retained in a floating arrangement forced upward solely by the enclosure top portion and restrained downward against the upward force at a seal frame height by the tensile restraints. Quick disconnects can permit manual seal frame release.

Abstract: A support platform for retaining a DAP system inflatable enclosure is provided that includes a top cover including a support surface defining a truncated access opening, a bottom cover including a panel, and a plurality of side covers each including a panel, in which the top, bottom and side covers are connected to form an airtight platform defining an interior for retaining an exercise device. A base opening of the enclosure can be secured at a perimeter region of the access opening above the exercise device. The platform further includes an exercise device upper interface for securing the support surface to an upper region of the exercise device, a lower interface for securing a lower region of the exercise device to the bottom cover or ground, and a blower interface for forming an airtight connection with a blower. The truncated access opening limits pneumatic forces secured by the exercise device.
