Multi-stage inversion tube mounting system

A mounting system for attaching a container to a vehicle configured to resist loads imparted by the container to the mounting system in sequential stages, the mounting system comprising:

• a first spring configured to elastically compress when subjected to a load imparted to the first spring by the container, the first spring having a useable load range from an initiation load to a maximum load at which the first spring is fully bottomed out;
• a first deformable member disposed serially with respect to the first spring, and configured to remain substantially un-deformed until subjected to a first deformation threshold load that equals or exceeds the maximum load at which the first spring is fully bottomed out, whereupon plastic deformation of the first deformable member ensues;
• and
• a second deformable member disposed serially with respect to the first deformable member, and configured to remain substantially un-deformed until subjected to a second deformation threshold load that substantially exceeds the first deformation threshold load, whereupon plastic deformation of the second deformable member ensues.

• and
• a second deformable member disposed serially with respect to the first deformable member, and configured to remain substantially un-deformed until subjected to a second deformation threshold load that substantially exceeds the first deformation threshold load, whereupon plastic deformation of the second deformable member ensues.
