Abstract
A seat includes a plurality of flexible belts, each extending in a loop about a fixed tubular member and an opposed rotatable tubular member, the tubular members being mounted in a seat frame. A pair of spaced extensible outer support arms are associated with each belt. Each pair of outer support arms is pivotally mounted on one end to rotatable support shafts on the seat frame and have upper ends slidably disposed in a belt loop to engage the points of contact between the top and bottom surfaces of a belt loop on opposite sides of a user of the seat. The belts and outer pivotal support arms are releasably latchable in the conformed position about a user. Pivotal inner leg support arms are coupled to an endmost pair of outer support arms to conform the inner portions of an endmost belt about a user.

A conformable member comprising:
- a frame;
- first and second tubular members mounted on opposite sides of the frame, at least the first tubular member being rotatably mounted on the frame;
- a plurality of belts spaced along the frame, each of the belts forming a loop having top and bottom opposed portions, the loop of each belt extending around the second tubular member and fixedly connected to the first tubular member and wound in an extensible number of turns about the first tubular member;
- belt lock means for locking each belt in a set length between the first and second tubular members;
- outer support means, mounted on the frame and associated with each belt, for engaging the belt adjacent the area of contact between the top and bottom portions of each belt after a user has contacted the belt urging the top portion of each belt into contact with the bottom portion of each belt;
- means for locking the outer support means in a position engaged with the belt;
- and
- means for rotating the outer support means and the belt lock means between positions.
