  • Patent number: 4565385
    Abstract: A tiltable supporting wheel chair having a tilting mechanism with front support wheels which pivot downward and outward engaging the floor and raising the front of the wheelchair and tilting it backwards. The tilting mechanism further includes a cross-frame pivotably attached to the frame of the wheelchair and activated by movement of an arm attached to it. The arm is controlled by a rod leading to a pivotal plate which is connected to a lever on the side of the wheelchair by a linkage. Upon movement of the lever, the linkage rotates the plate, moving the arm and cross-frame to extend or retract the front wheels. A locking mechanism prevents accidental movement of the level. Rear supports extend behind the wheelchair and engage the floor upon the front wheels being pivoted to their furthest point forward.
