Abstract
A wheelchair having an ergonomically designed seat assembly is provided. The seat assembly includes a backrest subassembly connected to a seat frame The backrest subassembly includes a backrest frame, at least one resilient pivotal member connected to the backrest frame, and a backrest connected to the at least one resilient pivotal member such that the backrest is capable of resilient pivotal flexing about a transverse horizontal axis. A seat is pivotally connected to the seat frame such that the seat is capable of pivotal tilting about a transverse horizontal axis relative to the seat frame and independent of the backrest subassembly. At least one resilient member is disposed between the seat frame and the seat so as to allow resilient relative pivotal tilting therebetween. Two leg rests are pivotally connected to the seat frame such that the leg rests are capable of pivoting about a transverse horizontal axis relative to the seat frame. The leg rests have a locking mechanism whereby the leg rests may be held in place at various angles relative to the seat frame.
