ABSTRACT:
A chassis in a wheelchair assembly interconnects forward large wheels having hand rims and a reclining chair via a recliner mechanism and supports side panels for the assembly. Rear caster wheels are connected to the rear of the side panels. The occupant of the wheelchair normally has his center of gravity centered between the forward and rear wheels. The chassis has an H-configuration as seen in plan. An underlying transverse tube of rectangular cross-section is welded to the undersides of two square cross-section tubes extending in the usual direction of travel of the wheelchair. One-half inch thick bars are welded to the transverse bar and inclined upwardly therefrom for mounting the axles for the large wheels. A horizontal brace is welded between the inclined bars and the upper aspects of the tubes of rectangular cross-section to provide an extremely strong and rigid all welded, all steel chassis.
