Abstract
An improved energy and shock absorber is provided using one standard off--shelf textile material for all the strap components having the same configuration and composition and varying only in length. Such a design enables the shock absorber to be fabricated and/or repaired economically and expeditiously at any installation or facility that has available a commercial sewing machine. The magnitude of shock absorption can be varied without the need for any research and development effort, and by operating personnel.
Claims10
A shock absorber comprising a pair of spaced load attaching fittings;
- a plurality of elongate tear members extending between and having their ends operatively connected between said fittings;
- all of said tear members being made of the same material having equal cross-sections and predetermined physical characteristics;
- said tear members extending for a portion of their length substantially in a common plane, in lateral side-by-side relationships;
- said tear members each being progressively longer in effective parting length;
- the effective lengths of said tear members being constructed so that a tensile force between said fittings is applied to at least two adjacent tear members simultaneously causing the force to be transferred between the tear members smoothly and continuously as the tear members are successively parted.
