Definitions
- the present invention relates to a suspension trauma relief strap assembly for use with a fall protection harness.
- Orthostatic intolerance also commonly referred to as “suspension trauma” may include symptoms such as light-headedness, breathlessness, palpitations, tremulousness, poor concentration, fatigue, nausea, dizziness, headache, sweating, paleness, increased or unusually low heart rate, unusually low blood pressure, loss of vision, weakness, and faintness.
- blood can accumulate in the veins, commonly referred to as “venous pooling”, and cause orthostatic intolerance.
- Venous pooling typically occurs in the legs due to gravity and a lack of movement, and an accumulation of blood in the legs reduces the amount of blood in circulation throughout the rest of the body. The body reacts by speeding up the heart rate in an attempt to maintain sufficient blood flow to the brain.
- Orthostatic intolerance may be experienced by workers using fall protection systems including fall protection harnesses. After a fall, a worker is suspended by the dorsal D-ring of the fall protection harness, and the worker is left suspended in a relatively vertical/upright position by the fall protection system until rescued. The worker may remain suspended in the fall protection harness for a length of time, and the sustained immobility may lead to a state of unconsciousness and/or any of the other above-mentioned symptoms. Depending upon the length of time the suspended worker is unconscious and/or immobile and depending upon the level of venous pooling, the resulting orthostatic intolerance may possibly lead to death. While not common, such fatalities are often referred to as “harness induced pathology”.
- footholds may be used to alleviate pressure on the workers’ legs and provide support for “muscle pumping” to activate the leg muscles and reduce the risk of venous pooling. Therefore, fall protection harnesses incorporating such footholds or trauma relief assemblies are desirable to reduce risk of suspension trauma.

Connector 103 engaged with connection mechanism 110 to form a connection assembly 200, 202, 220, 230240, which results in formation of a sling. Length of the sling can be adjusted by workers before strap 101 and connector 103 are stowed in first housing 100, by adjusting length of strap 101 during use, or a combination thereof. Worker may “stand” on sling while suspended in fall protection harness.
- presently disclosed trauma relief strap assemblies 510 can be deployed by workers using only one hand. In some examples, presently disclosed trauma relief strap assemblies 510, can be integrated into fall protection harness to avoid abrasion and snagging. In some examples, presently disclosed trauma relief strap assemblies 510 can provide a strap for workers to stand on rather than a connector or some other component. In some examples, presently disclosed trauma relief strap assemblies 510 provide any combination, including all three, of these benefits to workers at the same time.
- the worker Due to the fall, the worker is suspended by the dorsal D-ring, which pulls the shoulder straps upward and/or taut proximate the back of the worker.
- the sling is operatively connected to the portions of the shoulder strap being pulled by the dorsal D-ring (proximate the ends of the rear portions of the shoulder straps above the junctures with the seat strap), and when the worker “stands” on the sling, the pressure extends from the dorsal D-ring to the sling rather than to the worker. This allows for the load or ken off the worker’s body and the other straps of the fall protection harness because the load is applied from the dorsal D-ring to the sling instead.
- the other straps of the fall protection harness loosen so as to not constrict the worker’s body when suspended.
- the suspension relief strap assembly the worker is able to “stand” on the provided sling to relieve the pressure from the fall protection harness and reduce the risk of suspension trauma.
- the suspension relief strap assembly of the present disclosure may be retrofittable to accommodate most styles of fall protection harnesses.
- the presently disclosed suspension relief strap assembly is reusable on another fall protection harness should a fall occur and the fall protection harness must be discarded.
- the presently disclosed suspension relief strap assembly may also be sewn directly onto the fall protection harness rather than used as a retrofit, reusable accessory.
