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.

An extension assembly for selectively altering the aerodynamic shape of a vehicle comprising: a substantially air-tight outer shell of elastomeric material having a first desired contour when in the relaxed state an interior structure of flexible material which is substantially non-stretchable and which is coupled to the inside of said outer shell, said inner structure being shaped to define a second desired contour when it is tautened, and means for selectively introducing a gaseous medium into said outer shell so that the outer shell and inner structure expands from said first desired contour toward said second desired contour.
