Abstract: A ramp restraint apparatus for a vehicle includes an elongate, rigid restraint bar having one end rotatably attached to the ramp and a free end having a notch and a roller at its tip. The restraint bar travels over a bar support on a lock/release assembly mounted to a vehicle bulkhead. The bar support is shaped at one end to receive the notch of the bar and hold the bar in place when the ramp is fully deployed. A release arm has a cam follower that pushes up on and releases the restraint bar when the release arm is rotated, allowing the ramp to close. When the ramp is fully closed, a storage bracket receives and holds the inboard end of the restraint bar.

Abstract: A clearance-measuring break-away pintle hitch includes a mount having a first end for coupling to a vehicle. A pintle body has a portion thereof aligned with and coupled to a second end of the mount by a shear pin. Gauge members are pivotally coupled along a common axis of rotation to the pintle body. Each gauge member is rigid and has a unique length measured from the common axis of rotation. Each gauge member is independently rotatable about the common axis of rotation.
