Abstract: My invention relates to a device for providing additional traction and grip for aiding an automobile which has been disabled by a rut or a slippery road surface or stuck in mud, sand or snow. The device provides a belt having a wedge-shaped appendage at one end so that, if the belt is pulled under the wheel, the spinning is reduced or stopped, and the wedge provides additional traction and lift to free the automobile.
Abstract translation: 本发明涉及一种用于提供额外的牵引力和抓地力的装置,用于帮助已经被车辙或者滑溜的路面阻挡或被卡在泥土,沙子或雪中的汽车。 该装置在一端提供具有楔形附件的带,使得如果带被拉到车轮下方,则纺纱被减小或停止,并且楔形件提供额外的牵引力和提升以释放汽车。
