Self-tensioning girt
Described are self-tensioning girt assemblies with one or more straps that form loops that extend around opposing sides of an inflatable structure. The one or more strips are configured to apply multi-directional forces such that the girt assembly is self-tensioning. The self-tensioning girt assemblies may comprise at least two sleeves coupled to the inflatable structure and that receive the straps in a way that permits the straps to rotate around the inflatable structure. In some embodiments, the straps are attached to a panel that extends between the straps.
1. A self-tensioning girt assembly comprising:
at least two brackets;
a strap comprising
a first loop formed by positioning a first portion of the strap around a first end of an inflatable structure;
a second loop formed by positioning a second portion of the strap around a second end of the inflatable structure;
wherein an end of each loop is coupled to one of the at least two brackets;
wherein the strap is configured to slide around the ends of the inflatable structure when the inflatable structure is inflated to adjust a size of the loops so that tension applied to the strap by the inflatable structure is uniformly distributed between the at least two brackets.
2. The self-tensioning girt assembly of claim 1 , wherein each of the loops is positioned within a sleeve that is positioned around each end of the inflatable structure.
3. The self-tensioning girt assembly of claim 2 , wherein the strap slides around the ends of the inflatable structure within each sleeve.
4. The self-tensioning girt assembly of claim 1 , further comprising a panel comprising sides, wherein each side is attached to one of the first loop and the second loop.
5. The self-tensioning girt assembly of claim 4 , wherein the panel further comprises a first end that is attached to a third portion of the strap that extends between the first loop and the second loop.
6. The self-tensioning girt assembly of claim 5 , wherein the panel further comprises a second end that is positioned adjacent the inflatable structure.
7. The self-tensioning girt assembly of claim 5 , wherein the uniform distribution of the tension between the at least two brackets also applies a uniform tension to the first end of the panel.
8. The self-tensioning girt assembly of claim 4 , wherein the panel extends between the inflatable structure and a passenger vehicle doorway.
9. The self-tensioning girt assembly of claim 8 , wherein the panel is configured to serve as a footstep.
10. The self-tensioning girt assembly of claim 4 , wherein the panel is flexible and tensioned.
11. The self-tensioning girt assembly of claim 4 , wherein the panel is rigid.
12. The self-tensioning girt assembly of claim 1 wherein the at least two brackets are attached to a passenger vehicle.
