Abstract
A leg prothesis device for use as an upper leg prothesis permitting the wearer of the device to kneel thereupon comprising a first member adapted to support an upper leg prosthesis and a second member spaced from the first member adapted to support a lower leg portion connected to a foot prothesis. The first and second members are movable with respect to each other between a maximum leg angle of about 180.degree. and a minimum leg angle of about 20.degree.. A connecting member connecting the first and second members comprises three arm portions: (1) a curved portion pivotally connected at one distal end to the first member and defining a pivot axis between the first and second members; (2) a first linear portion that is integral with the curved portion; and (3) a second linear portion angularly connected to the first linear portion. The second linear portion is fixedly connected to said second member with the curved portion being pivotably connected to the first member at a point located intermediate a vertical extension of the second linear portion and a vertical axis of the second member when the leg angle is about 180.degree.. The first member is provided with a slot through which the first linear portion extends and moves.
