HOW F1 SAFETY BELTS LOST WEIGHT












A Formula 1 safety belt evolves quickly through the seasons, just as every device used in the main motorsport series. OMP, though, has raised the bar even more dramatically, when the Dyneema safety belt broke through becoming (and still being) a favorite for many teams and drivers. Let’s compare it with the first ever safety belt directly developed by OMP, Robert Kubica’s “Formula” (2010).

WEIGHT
The main difference between the two harnesses is the weight, which is also the real “obsession” in F1. Polyester was the best choice until 2010, but the weight of a belt was 900 grams. OMP conceived the Dyneema safety belt to reduce drastically the weight compared to the old Formula: the total weight is now 480 grams.
“DELICATE AREAS"
The crotch straps must pass through the groin area, that are obviously delicate. A problem with relatively hard polyester while soft material attenuates the friction between harness and those areas so Dyneema, with its softness, has had a big success from the get-go.
WHAT’S THE TAPE MADE OF
What is the lightness determined by? Mainly by the material that makes up the tape. 2010 Formula was made of polyester, like most harnesses in those years. The Dyneema takes its name from the fiber OMP can use under exclusive license for motorsport. It’s a lighter and more resistant fiber, whose color (white) is peculiar because it can’t be dyed, unless you want to waste its extreme softness.
NEW BUCKLE
The buckle has been re-designed to be less invasive in the cramped space of a formula car cockpit: the trigger doesn’t come out of the main body anymore. Also, the design has been extremized in order to reduce the weight as much as possible.
AND WHAT ABOUT THE METAL PARTS?
The buckles of “Formula” were made of steel and aluminium; the latter is still present in the Dyneema, but bound to the lighter titanium and magnesium.
THE RING
The “D Ring” is the belt loop that allows the crotch strap to pass over the other straps and get into the buckle. In order to avoid the presence of a rigid part in that area, the metal D-ring has been replaced by a loop in the tape.
