The prompt
A detailed 3D mechanical assembly of a convertible wheelchair that transforms into a flat bed. The design features a load-bearing aluminum tubular frame with articulating pivot joints at the seat-to-backrest and seat-to-legrest intersections. The backrest reclines exactly 180 degrees horizontally, while the dual leg rests elevate to form a continuous, flush surface with the seat pan. Includes locking mechanical struts for structural support in the flat bed configuration, drop-down armrests, large rear drive wheels with handrims, and front swivel casters. Parametric design, clean topology, functional linkages, realistic mechanical tolerances
