ABSTRACT:
A mobile chair for the handicapped includes a seat frame, a front support frame and a removable rear support frame. The seal frame is pivotable with respect to the front support frame selectively to vary the position of the seat frame. The rear support frame is releasable from the front support frame and is connected thereto by a toggle mechanism at the rear and a pivotal releasable ball and socket joint at the front. To place the chair in a car or other vehicle, the front of the chair is first placed on the vehicle floor, the rear toggle connection is released and the seat frame and front support frame are placed on the vehicle seat. The ball and socket joint permits the seat frame and front support frame to be pivoted into the car and placed on the seat while the rear support frame remains essentially stationary outside the vehicle. Once the chair is in the vehicle, the ball and socket connection is released and the rear support frame may be removed and stowed elsewhere.
