A support frame for a knee pad has three major components that interlock with each other to form a rigid and strong frame capable of supporting the weight of a person who is working on knees. The three components are molded of a rigid plastic material. The upper component has a knee seat and a strap for wrapping around the leg of the wearer; the lower component has a cuff for wrapping around the wearer's ankle. Fastener devices for attaching the knee pad and the straps to the support frame are either incorporated into or provided on the support frame. |
