Current designs for articulating wheelchair legrests do not provide the extension and elevation needed to reduce hip flexion and increase blood circulation. Existing products and patents for available articulating legrests are not as durable as the nonarticulating variety. To solve these problems, an articulating wheelchair legrest that consists of a planar six-bar linkage coupled with a linear slider to reduce binding with the slider was designed and built. When compared to an articulating design developed by a student group in 2002-2003, this design decreases the overall size and weight and increases durability.
