Abstract
A cargo airbag structure system for use within a cargo bay of a transport vehicle in order to buffer and stabilize loads, such as, for example, large paper rolls or drums, comprises two inflatable bladders disposed in an overlapping disposition with respect to each other within a sealed, expandible, multi-ply paper container. When interposed between the cargo load rolls, the airbag structure conforms to the external contours of the cargo load rolls which serves to not only enable the airbag system to buffer and stabilize the cargo loads, but in addition, the airbag system is stably retained between the cargo load rolls. In order to prevent friction, abrasion, or pinching of the bladders during the inflation process as well as during use of the airbag system when the bladders are disposed in their inflated state, the inflatable bladders are disposed within encasing sleeves which fully envelop the bladders along the longitudinal extents thereof, the opposite ends of the sleeves being open. By preventing the noted friction, abrasion, and pinching of the bladders, the structural integrity of the bladders is preserved resulting in enhanced service life.
