US Patent 10960806 Vehicle ramp resistant apparatus

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.
