ABSTRACT:
A new and improved wheelchair tilting apparatus includes a base assembly and a wheelchair receiving assembly supported by the base assembly. The wheelchair receiving assembly includes a first platform portion and a first frame assembly supporting the first platform portion. The wheelchair receiving assembly also includes a second platform portion and a second frame assembly supporting the second platform portion. The first and second frame assemblies are connected to each other and oriented with respect to each other at a predetermined obtuse angle, such that the first and second platform portions are oriented with respect to each other at the predetermined obtuse angle. A tilt assembly is supported by the base assembly and is provided for tilting the wheelchair receiving assembly after a wheelchair is received in the wheelchair receiving assembly. The tilt assembly includes an electric motor and a gear assembly that is connected to the wheelchair receiving assembly, such that the tilt assembly controls a tilt angle of the wheelchair receiving assembly and the wheelchair supported thereon. Wheel assemblies are connected to bottom portions of the base assembly. A wheel-stop assembly is connected to the first platform portion for preventing rolling of the wheelchair when the wheelchair is resting on the first platform portion. A wheelchair backstop assembly is connected between respective first and second side frame assemblies that are connected respectively to the first and second frame assemblies. A headrest assembly is also connected between the first and second side frame assemblies.
