ABSTRACT:
An air cushion crutch pad generally includes a sealed hollow chamber having an air cushion therein, and a cavity which provides means for removably mounting the crutch pad to a upper cross piece of a crutch. Opposing sidewalls of the sealed hollow chamber include rounded upper portions and straight vertical lower portions. A line of inflection provides means for controlling compression of the sealed hollow chamber. A rib, dividing the sealed hollw chamber from the cavity, provides means for stabilizing the sidewalls to prevent collapse thereof. The air cushion crutch pad may be unitary in structure and made of a rubberlike material.
