ABSTRACT:
This brake assembly can be readily adapted for use with a conventional wheelchair. It provides a hand brake assembly adjacent each side frame including first and second links pivoted to the side frame and a third link connected between said first and second link. An arm rest is pivotally connected to the upper portion of each side frame and is connected at its front end by a link assembly to the hand brake assembly so that downward movement of the front of the arm rest actuates the hand brake assembly into engagement with the wheel.
