ABSTRACT:
Disclosed is an inflatable cushion configured with a substantially flattened tubular shape such that in an inflated state the inflatable cushion is highly adaptable so as to readily conform to the terrain of the underlying surface on which it is deployed and to the footprint of the vehicle tire as the vehicle is driven across the device. During typical use the cushion is not fully inflated and operational inflation pressure is generally less than 10 PSI and preferably 5 PSI. For use the cushion is deployed such that the central axis of the tube is substantially parallel to the driving direction of the vehicle. The inflatable automotive traction recovery tool of the present invention simultaneously lifts the vehicle and provides a driving surface with sufficient pressure against the tire and underlying surface to allow the vehicle to drive on it. The inflatable automotive traction recovery tool of the present invention is able to negotiate a wide variety of obstacles such as, but not limited to, bridging over a ditch, providing a ramp to climb a steep step, providing traction on soft ground and low friction surfaces, and providing support when one or more wheels of the vehicle lose contact pressure with the ground.
