ABSTRACT:
A seat assembly for releasable attachment to the center post of a conventional crutch comprises a planar sitting board with a support board hingedly attached thereto. In a first embodiment, a sleeve is affixed to a hinge which is affixed to the back edge of the sitting board. The sleeve may be slidingly fit over the top end of the crutch center post and thereby maintain the seat assembly in the open, ready position wherein the sitting board is substantially horizontal and the crutch and support board are vertically oriented, being spaced apart by the sitting board. In a second embodiment, a bracket having a pair of grooves is attached to the sitting board and attaches to a pair of spaced bolts affixed to the crutch center post. Additional securing means are provided in the form of a stabilizer rod extending from the center post to the support board.
