Abstract: In a military vehicle having a cargo box containing two facing troop seat semblies, the improvement comprising a rigid cargo box cover mountable on the box to shield the seated military personnel from the weather, said cover being formed of disconnectable panels for knockdown into a relatively flat storage package. The rigid cover is connected to the cargo box and also to the back structures of the troop seat assemblies so that the cover and seat assemblies act as mutual reinforcements for one another.

Abstract: Improved cargo tiedown anchor means adapted for removable mounting in a vcle cargo box to anchor the ends of flexible cargo-retention straps while the vehicle is in motion or in transit. The anchor means comprises a first anchor system near the box front wall and a second anchor system near the box tailgate. Each anchor system includes a rail extending the width of the cargo box and a series of curved rods welded to the rail at spaced points therealong. The rods form eyes to receive hook-like end connectors carried by the flexible cargo tiedown mechanisms.

Abstract: A shutter mechanism for an engine radiator comprising a series of rigid pus tubes having elastomeric sleeves secured thereto. Introduction of pressurized fluid (e.g. compress air or engine coolant) into the porous tubes pressurizes the spaces between the tubes and sleeves, thereby causing the sleeves to balloon outwardly to fully or partly close the air supply passage leading to the radiator. Depressurization of the tube interior spaces allows the elastomeric sleeves to contract onto the tubes, thereby opening the radiator air passage system.
