Support Assembly With Selective Orbital Rotation About Bracket

A support assembly for a wheelchair, the support assembly comprising:

• a fixable portion adapted to be fixedly mounted to the wheelchair, the fixable portion including:
• at least one mount adapted to be mounted to the wheelchair;
• and
• a shaft having a keyway formed therein, the shaft being supportable by the at least one mount;
• and
• a rotatable portion received on the shaft of the fixable portion and being in selective locked engagement therewith, the rotatable portion including:
• a bracket body defining an opening into which the shaft of the fixable portion is received;
• and
• a key member providing a key, the key member being supported by the bracket body and movable in linear translation between an engaged position in which the key is engaged with the keyway in the shaft to lock an orientation of the bracket body of the rotatable portion relative to the shaft of the fixable portion and a disengaged position in which the key is disengaged from the keyway in the shaft to permit the rotatable portion to rotate relative to the fixable portion about an axis of rotation defined by the shaft.
