Simpson Seat Belts and Harnesses for Experimental Planes

Simpson Performance Products manufactures 5, 6 and 7-point aviation harnesses for experimental planes, aerobatic planes and historical/military restoration planes. We offer our most popular configurations along with fully customized harnesses stylized to the owner’s specifications. Simpson aviation harnesses are made in the USA and backed by Simpson’s 60 years of experience and research in motorsports safety.


Studies of serious accidents have shown that the proper use of shoulder harnesses, in addition to the safety belt, can reduce major injuries by 88 percent, and fatalities by 20 percent.

Simpson’s own research shows us that the use of a 5, 6 or 7-point harness can have a major impact on occupant safety. After a number of auto racing fatalities in the 90's, Simpson Engineering went to the labs and established a library of proven practices that save lives.



Simpson Restraint Philosophy:

1. Restraining the pelvis reduces torso and head injury numbers.

2. For optimum restraint, use 5, 6 or 7-point harnesses, no 4 point systems. Use quick release camlock systems. Do not use retractors.

3. All Simpson restraint systems use Polyester webbing over Nylon for superior performance in stretch and longevity.

4. Apply data for a significantly higher performance rating.

All restraints available in

Latch and Link or Rotary Camlock
