Abstract
A pair of identical side frames (A) are each made up of a pair of generally L-shaped tubular members which are welded together. A reinforcing tube (30) is slidably received within a forward portion (14) of each side frame to strengthen an interconnection with a front wheel assembly mounting bracket (32) with mechanical fasteners. A swing away leg rest mounting bracket (50) is also connected with the forward tubular portion and reinforcing tube for selectively supporting a swing away leg rest assembly thereon. A folding mechanism (D) includes a pair of pivotally connected seat support structures (100). The seat support structures include seat side supports (102) which have a longer free end (106) and shorter free end (108), cross mambers 104 and fittings (120). Circumferentially disposed grooves (124) are offset in such a manner that the seat support structures are interchangeable. An arm rest assembly (F) is releasably connected with the side frames with brackets (162, 174) such that the arm support structure can be selectively removed form the brackets or pivoted about one of them.
