ABSTRACT:
A traction mat is disclosed for use under a vehicle wheel to provide traction under conditions such as snow, ice, and the like. The mat includes a generally flat body having cleats which are movable relative to the body between inoperative condition substantially out of engagement with the ground and operative condition in engagement with the ground in response to the vehicle wheel moving over the mat. The cleats are disclosed as individual spike-like members reciprocally mounted within bores in respective elements of the body. The elements are formed in a series of generally parallel rows providing flexibility for the body. The spikes are axially movable relative to the body between inoperative positions and operative positions gripping the ground in response to the vehicle wheel moving over the spikes.
