Abstract
Anti-tip mechanism for wheelchairs having wheels on a rear axle. The mechanism includes left and right side sections that are each attached to an exterior end of the rear axle with a bracket. Each side of the mechanism extends perpendicular to the axle when the mechanism is in a functional position and parallel to the axle when in an idle position. The bracket is equipped with a hinge plate mounted at an angle; whether the angle is positive or negative depends on whether the bracket is part of the mechanism's left side or right side. A support arm is rotatably coupled to the hinge plate by a locking mechanism and includes a support roller at the other end. Release of the locking mechanism allows movement of the support arm between the functional and idle positions.
