Abstract

A vehicle traction device for passenger cars and alike including a flexible belt-like traction mat with transverse corrugations on one side and substantially smooth on the other side. One end of the mat is pivotally secured to anchoring means including a flexible anchoring pad and ground gripping element. In use, the traction mat is first arranged to form a loop relative to the anchoring means. With its corrugations facing a tire and its smooth side facing the ground the traction mat will easily be drawn under a spinning wheel until that end of it, which is secured to the anchoring means becomes choked by the anchoring means. The tractive effort then developed causes the anchoring means to become wedged and thus assuring its fixed position, whereby the traction mat is prevented from being propelled away by the driven wheel.
