  • Towing device for vehicles
    Patent number: 6971662
    Abstract: A towing device (1) for motor vehicles includes an elongated element (2) having a length, a cross section, a first end portion (13) and a second end portion (5). The cross section of the elongated element (2) at least along a part of the length of the elongated element (2) is designed to be hollow. The first end portion (13) is designed to be connected to a motor vehicle. The towing device (1) further includes a lug (3) being connected to the second end portion (5) of the elongated element (2). Due to the hollow cross section, the mass of the towing device (1) is substantially reduced.
