Abstract
A seat bottom assembly including a first frame subassembly and a second frame subassembly supported by and rotatably coupled to the first frame subassembly about a rotation axis, the second frame subassembly configured to rotate about the rotation axis between a first position and a second position. A fabric diaphragm has a fore end connected to the second frame subassembly and an aft end connected to the first frame subassembly. The rotation axis is positioned forward of the connection of the aft end of the fabric diaphragm to the first frame subassembly, such that when the second frame subassembly is in the first position the fabric diaphragm is stretched, and when the second frame subassembly is in the second position the fabric diaphragm is relaxed. In use, the first position may correspond to sitting and the second position may correspond to under seat access.
