Abstract
A prosthetic foot having an adjustable height heel includes a frame portion with an ankle link pivotally supported on the frame portion at a first pivot axis. A detent rod is pivotally connected to the ankle at a second pivot axis, and a detent member is pivotally affixed to the frame portion at a third pivot axis. The detent member is selectively operable to receive and releasably retain a length of the detent rod therein so that the length of the detent rod extending between the second and third pivot axes may be selectably adjusted. When the length of the rod is so adjusted, the angular relationship of the frame portion and the ankle link is changed thereby changing the heel height of the foot. The detent mechanism may be activated by various means including fluidic means, mechanical means, electromechanical means, and the like.
