Abstract
Safety devices for vehicle tire carriers including safety features that protect against the tire being dropped upon a failure in a cable system that supports the tire in a stowed condition. In one implementation the tire carrier has a support shaft at least partially housed within a longitudinal sleeve having a window. A pivotable arm has a first feature that engages with a portion of the support shaft to limit downward movement of the support shaft within the longitudinal sleeve when the pivotable arm is in a first rotational position and upon a failure in the cable system to properly support the tire in the stowed condition. The pivotable arm may also have a second feature that engages with the longitudinal sleeve to inhibit the arm from pivoting away from the first rotational position upon a failure in the cable system to properly support the tire in the stowed condition.
