A restraint device for securing a tire to an apertured surface and which fits in a safe space under a vehicle includes a base, a support, an abutment and an activation system. The base secures the restraint device to an apertured surface. The abutment, which is attached to the support, which in turn is slidably attached to the base, is moved into engagement with the tire using the activation system to prevent movement of the tire. The activation system has a rotational device such as a lever. The abutment may have a wedge shaped lateral support, and a positioning spring to maintain the abutment in a retracted or extended position. The restraint device may have an indicator to show that the device is properly set in the apertured surface, and a handle that collapses into the safe space when not in use. |
