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.
Claims20
A restraint apparatus for a vehicle ramp that can be deployed and retracted, comprising:
- an elongate, rigid restraint bar having an inboard end and an outboard end, said outboard end configured to mount to an interior surface of the ramp, said inboard end having a notch disposed on the underside thereof;
- and
- a bar support mounted on an interior bulkhead of the vehicle proximate to the ramp, said bar support having an edge shaped to accept and hold said notch when the ramp is fully deployed;
- wherein
- said restraint bar is configured to travel over said bar support as the ramp is deployed and retracted.
A restraint apparatus for a vehicle ramp that can be deployed and retracted, comprising:
- an elongate, rigid restraint bar having an inboard end and an outboard end, said outboard end mountable to an interior surface of the ramp, said inboard end having a rounded notch disposed on the underside thereof and an end roller mounted on its tip;
- a storage bracket mounted on an interior surface of the vehicle, said storage bracket configured to accept and hold said inboard end of said restraint bar when the ramp is fully retracted;
- and
- a lock/release assembly comprising
- a weldment plate mounted on a bulkhead of said vehicle proximate to the ramp, and
- a bar support mounted on said weldment plate, said bar support having a rounded edge shaped to accept and hold said notch when the ramp is fully deployed;
- wherein
- said restraint bar is configured to travel over said bar support as the ramp is deployed and retracted.
A ramp system for a vehicle having a cargo compartment with a deck, comprising:
- a rotatable ramp having a point of rotation proximate to the deck and configured to open outward from the cargo compartment when deployed;
- a cable having a first end attached to an interior surface of said ramp and a second end coupled to a winch;
- an elongate, rigid restraint bar having an inboard end and an outboard end, said outboard end rotatably mounted to said ramp, said inboard end having a notch disposed on the underside thereof and an end roller mounted on its tip;
- a storage bracket mounted on an interior surface within the cargo compartment, said storage bracket configured to accept and hold said inboard end of said restraint bar when the ramp is fully retracted;
- and
- a lock/release assembly comprising
- a weldment plate mounted on a bulkhead within the cargo compartment proximate to said ramp,
- a bar support mounted on said weldment plate, said bar support having a rounded edge shaped to accept and hold said notch when the ramp is fully deployed;
- wherein
- said restraint bar is configured to travel over said bar support as the ramp is deployed and retracted.
