US Patent 10112652 Three-wheeled vehicle crumple zone

A three-wheeled vehicle crumple zone is described. The crumple zone includes a triangular, single-sided swing arm coupling a wheel to a frame of the vehicle at an end-most portion of the vehicle. The swing arm includes a u-shaped frame yoke coupling the swing arm to the frame and an angled wheel yoke coupling the wheel to the swing arm. The wheel yoke extends from the frame yoke at an angle ranging from 40 to 70 degrees, such that the frame yoke, the wheel yoke, and a centerline axis extending perpendicularly from the frame yoke form a right triangle.
