Abstract: The device is a cargo restraint mechanism for restraining cargo pallets. The mechanism includes two links rotatably attached to a frame member, and a latch member pivotably attached to the links. One link is provided with a lever and the latch includes a cargo restraint lip. The mechanism is erected by pressing the lever thereby raising the restraint lip above the plane of the top surface of the frame and into a cargo pallet engaging position. A downward force delivered to the top surface of the restraint lip retracts the restraint mechanism beneath the plane of the top surface of the frame. A helper leaf spring follows a cam surface on the other link causing a snap-type action in the mechanism. The frame may include an additional mechanism such as a separately actuatable and retractable seat pallet guide.
