Abstract: A roller restraint assembly is removably mounted on the floor of a vehicle in an outboard location where it restrains cargo movement laterally but permits longitudinal cargo movement along its roller. This assembly has a pivotally mounted restraint arm which engages the base portion of a cargo pallet and restrains the pallet against vertical movement. When the cargo is moved longitudinally it drives the restraint arm aside on its pivot, thereby permitting longitudinal movement of such cargo. A roller is rotatably mounted on the assembly to facilitate longitudinal movement of the cargo while restraining lateral movement thereof. The roller further has a dampener incorporated therein which dampens and attenuates the impact of loads thereagainst.

Abstract: A roller assembly is removably mounted on the floor of a vehicle. This assembly has a retracted configuration adapted for moving cargo therelong in a first direction and an erected configuration for moving cargo in a second direction normal to the first direction. A first set of rollers is mounted in the assembly for universal movement.
