Abstract: A method for controlling a DAP system is provided that includes calculating a user seal interface height based on an estimated user height, and based thereon determining an attachment carriage height and a usage carriage height different than the user seal interface height. The method also includes driving powered vertical lifts to raise each carriage to an attachment position at the attachment carriage height while the user is in the DAP system through the top opening including raising about the user the seal frame attached to the carriages and thereby raising the top opening attached to the seal frame, and also controlling the lifts to retain the attachment position during user seal attachment and confirming the attachment. Responsive to confirming, the method includes driving the lifts to move each carriage to a usage position at the usage carriage height and inflating the enclosure to an unweighting.

Abstract: An inflatable unweighting enclosure for an exercise device is provided formed from a pair of opposing sheets attached to each other by a seam along a closed shape at their perimeter portions, each of which has a top region, an opposite base region, and central region. A trim path interrupts each articulated shape at the base region that defines a perimeter of a base opening for the enclosure when inflated, in which the base and base opening are substantially planar and the base perimeter defines an enclosure inlet. When inflated, the pair of flexible sheets expand laterally apart to define an enclosure inner space and form an elongate, disc-shaped structure interrupted by the base opening. The base opening attaches to a base support of the exercise device, which is shaped and sized to orient and support the enclosure vertically for providing unweighting to a user attached to a top opening.

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.

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.
