Abstract
An articulating leg rest is provided having a first member pivotally connected to a base frame. The base frame may be either connected to or part of a wheelchair frame. A second member is telescopically received by the first member. A drive system includes a motor-driven lead screw. First and second housings each have internally threaded portions engaged with the lead screw. A link connects the first housing to the base frame. The second housing engages the second member. Rotation of the lead screw advances the first housing along the lead screw, moving the link and causing the first and second members to rotate relative to the base frame. Rotation of the lead screw also advances the second housing along the lead screw, causing the second housing to linearly translate the second member relative to the first member.
