Claim Text:
1. A prosthetic foot and ankle assembly comprising a combination of: a foot component, and an ankle joint mounted to the foot component and having a fixed range of dorsi-plantar flexion during walking, the ankle joint comprising a joint mechanism providing resistance to ankle flexion, wherein the joint mechanism comprises: wherein the joint mechanism includes a first flexion limiter that limits dorsi-flexion of the joint mechanism to a dorsi-flexion limit and a second flexion limiter that limits plantar-flexion of the joint mechanism to a plantar-flexion limit, thereby defining said fixed range of dorsi-plantar flexion, the first and second flexion limiters comprising mechanical end stops of the joint mechanism, and wherein the joint mechanism is non-electronically controlled and the hydraulic damping provided by the hydraulic linear piston and cylinder assembly is non-electronically controlled.
