ABSTRACT:
A wheelchair lift for tilting a wheelchair and occupant backwards to a position for having his or her hair dressed or dental work or the like performed includes a pivotable frame onto which the wheelchair is rolled and secured. The lift also includes a fixed frame, a telescoping arm pivotally attached to the fixed frame and to the rear of the pivotable frame, and an electric motor drive which retracts and extends the telescoping arm to pivot the pivotable frame and wheelchair attached thereto about a pivot axis where the pivotable frame and the fixed frame are connected. The pivotable frame includes a horizontal section and an upright section which are connected at the pivot axis. The upright section includes a headrest which is adjustable. In one position the headrest supports the head of the occupant to allow work such as dental work to be performed while in a second position the headrest is retracted beneath the level of the wheelchair to allow free movement of the occupant's head to permit hair-washing and the like.
