A wheelchair anti-tip mechanism including an adjustable base that is bolted to the lower frame of a wheelchair inside of the wheels and below the center of gravity. Telescoping legs are placable into the sides and rear of the base in an outrigged fashion and are capable of extension out from and retraction into the base. The forward legs are adjustable and, when extended provide sufficient tilt toward the rear outrigged legs so as to raise the main wheels of the wheelchair off the ground. Once the wheelchair is rigged with the legs, and the forward legs adjustably extended, it becomes practically impossible for an unattended occupant to tip over the chair. When not in use, the legs may be stowed in the rear portion of the adjustable base.
