Abstract
The universal curved towbar comprises a pair of curved arm assemblies which are pivoted upon a coupler assembly, and diverge to include bumper mounting assemblies on their distal ends. The curved arm assemblies lie in a lateral plane, with their convex surfaces facing each other, thereby allowing significantly improved clearance between the bumper of the towing vehicle and the arm assemblies themselves. At the distal ends of the curved arm assemblies are three distinct bumper engagement means, including a lower bumper clamping chain which is tensioned against an upper bumper clamp, together with a redundant tensioning through a safety chain attached to the frame of the towed vehicle. At the distal ends of the curved arm assemblies there is further provided a spreader bar assembly, which both adjustably maintains the bumper mounting assemblies in position, and adds significantly increased overall rigidity to the entire towbar assembly.
