摘要： 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.

摘要： A power chair is provided comprising a frame transversely foldable between operating and transport positions. A seat is connected to the frame, with a pair of drive wheels also connected to the frame. The drive wheels are rotatable about a transverse axis below a portion of the seat supporting an occupant's thighs. The power chair further includes motors for driving respective drive wheels. Perspective motor/drive wheel combinations are pivotally connected to the frame. At least one ground-engaging idler wheel is connected to the frame, located rearward of the drive wheels. At least one anti-tip wheel is positioned above ground, forward of the drive wheels, and connected to the frame for movement relative to the frame upon encountering an obstacle.

摘要： A mid-wheel drive power wheelchair is provide having a pair of drive wheels on the support frame below the seat. Castor wheels are positioned behind the drive wheels and rearward of the seat. A pair of anti-tip idler wheels are positioned forward of the drive wheels on opposite sides of the frame. The anti-tip wheels are normally positioned off the ground when the drive wheels and the castor wheels are in their normal ground-engaging position. The anti-tip wheels have a resilient mounting comprising a support arm attached at a rear end to the frame. The forward positioned anti-tip wheels are movable upwardly about the attachment of the support arm, with the suspension resiliently resisting such movement, in response to the engagement with a curb or obstruction or in response to a forward pitching of the chair about the drive wheels.
