A vehicular cabin comprising: a substantially rigid body, endlessly arcuate in all cross sections in the form of Fig. 1 and in middle cross sections in the form of FIG. 12; and a shock-absorbing cushion around at least the bottom and a substantial portion of the sides of the body, comprising flexible foam plastic or yieldable fibers, and flexible, inflated tubes or balloons in the plastic or fibers. The wall of the rigid body includes: cans or tubes that are imbedded in substantially rigid foam plastic and optionally form part of stave-like elements whose bonded-together sides converge inwardly toward each other; mesh that tightly surrounds the foam plastic and cans; and stucco (containing plastic or portland cement) on the mesh. Balloon means, having a center of lift above the cabin's center of gravity, stabilize the vehicle against pitching and rolling. Inflated flexible tubes having tapered, flattened ends, of several uses in the cabin, are disclosed. |
