Abstract
A collapsible vehicle extension assembly for vehicles and a method for fabrication of such an assembly. The extension has an elastomeric outer shell and an inner structure of flexible non-stretchable membranes which define a plurality of separate air chambers when a gaseous medium is introduced into the outer shell. The interior membranes are semi-permeable to allow gradual equalization of pressures throughout the assembly during inflation while preventing the instantaneous deflation of each chamber from impact on the outer shell. Various interior chamber configurations are shown as well as a plurality of inflation techniques for different purposes.
