1. A progressive strap assembly comprising:
- a strap having a length defined by an elongate body having a first elasticity and a first end;
an elastic body having first and second ends, the second end of the elastic body anchored to the first end of the strap, and having a second elasticity different from and greater than the first elasticity of the strap, the elastic body having a maximum stretchable length;
a tension limiter having first and second ends secured to the first and second ends of the elastic body, respectively, the tension limiter being non-stretchable in a longitudinal direction and arranged to inhibit a predetermined stretchable length of the elastic body short of the maximum stretchable length;
a retainer secured to the second ends of the elastic body and the tension limiter;
a dosing device having at least one elongate element coupled to an end of the retainer, the dosing device arranged for incremental adjustment of a length of the at least one elongate element between the dosing device and the retainer;
a flexible sleeve secured to the dosing device through which the at least one elongate element extends, the second ends of the elastic body and the tension limiter are arranged to linearly slide through the sleeve with the retainer upon the incremental adjustment of the dosing device, the first end of the strap being maintained outside of the sleeve.
