Abstract: A wheelchair has a base and further comprises a seat frame mounted for tilting with respect to the base, and a seat frame tilting mechanism for rotating the seat frame with respect to the base. A back frame is mounted for reclining with respect to the base, and a back frame recline mechanism is positioned for rotating the back frame with respect to the base. A controller is provided for separately controlling the seat frame tilting mechanism and back frame recline mechanism so that the seat frame and the back frame can be rotated independently.

Abstract: An adjustable linkage assembly supports the footplate of a wheelchair footrest. The wheelchair footrest has a tube supported by the wheelchair frame. The linkage assembly comprises a plurality of pivots and a plurality of clamps. The clamps are structured and configured to releasably couple the pivots and the footplate together and in substantially fixed positions relative to one another. An extension tube is for use with a hanger mounted to a forward portion of a wheelchair. The extension tube adjustably supports a wheelchair footplate. The extension tube is engageable with a hollow portion of the hanger. The extension tube and the hanger are structured and dimensioned to be matingly engageable with one another and to prevent rotation of the extension tube relative to the hanger.
