Abstract
Abstract Air bags are provided along the length of the car and are inflated to apply pressure against the lading in a generally transverse direction. The air bags may act upon panels or upon a flexible covering. Various lading loading schemes are accommodated by applying different amounts of pressure to individual bags. Thus the problem of lateral shift of the lading is avoided or reduced.
