grounded Three-Point-Seating TPS System

The Issue

minimal-bearing-supportMost common storage device for Skydive Harness-Container-Systems is a simple crossbar-tubing. With an avg. tube diameter of 50mm (~2″) a BigBoy Rig with 40mm belts load mechanically on a gross support surface about 65cm² (~10 sq. “). This is even less than a smartphone display!!!


Main Problem:

High Tension Force Peaks @ Shoulder Harness


The Consequences


Considering the stress curve the effective bearing area which holds ~80% of the weight is approx 1/3 of the upper arc. That effects partly enormous tension force peaks on the shoulder harness and may cause fatigue of material. Definetely it is counterproductive for safety relevant equipment and reduces lifetime of airworthyness.

Worst case:

Torn shoulder harness due to continously heavy loading effected by harness T-bar hanging.



The Innovation

The Idea

Starting point for the concept design was the Focus on ideal safe-keeping for skydive aerial sports equipment. Thinking about the “natural habitat” of the harness-container-system is, of course, on a skydivers back while having an awesome time in the sky. Keeping this in mind, we developed the advanced concept of the grounded TPS technology.

The Technology

The innovative grounded gStool system is designed to distribute the weight on a relatively big contacting surface. This effects steady loading without any force tension peaks on certain areas. The Parachute Container lays mainly on the gStool system so the upper crossbar has only a stabilizing function. In effect the shoulder harness is only bonded through fixation, preventing the Rig from tilting sidewards. Grounded advanced skydive gear technology provides a always proper, secure fixing and keeps your gear in perfect shape.
