    • 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.
    • 提供了一种铰接腿托,其具有枢转地连接到基架的第一构件。 基座框架可以连接到轮椅框架的一部分或轮椅框架的一部分。 第二构件由第一构件可伸缩地接收。 驱动系统包括电动丝杠。 第一和第二壳体各自具有与导螺杆接合的内螺纹部分。 链路将第一壳体连接到基架。 第二个壳体与第二个构件接合。 导螺杆的旋转使第一壳体沿着导螺杆前进,使连杆移动并使第一和第二构件相对于基架旋转。 导螺杆的旋转还使得第二壳体沿着导螺杆前进,使得第二壳体相对于第一构件线性平移第二构件。
