Since years, Sven Krieter is our specialist for the Formula-1-SCHUBERTH helmets for the professional drivers. It is he who is at every Grand Prix to prepare the helmets for the race. He cannot make any mistakes. The drivers trust him.
Sven Krieter attends the Formula-1-Teams to all races and testing to provide the optimum support for all drivers. Every year he flies about a quarter of a million kilometres but he cannot imagine a better job for himself.
My first race was at Silverstone in 2005. Before that, I have never taken a plane. In addition, suddenly I found myself in the Heathrow rush, left-hand traffic and I had no navigation. That was quite hard back then.
Every year, SCHUBERTH produces around 80 SF1 PRO racing helmets for Formula 1 drivers. In 2018, the legendary racing helmet will be replaced by the SF2 PRO.
The helmets are adjusted individually and prepared in an extra department within the factory – all done in handwork. “The drivers need to feel comfortable. So together we try different versions until everything is fits perfectly”, Krieter says. If it comes to the visors and to the special mini-spoilers above the forehead and at the back of the head, then the pilotes have the final say. For every Formula-1-weekend Sven Krieter has six different versions of visors for every helmet prepared.
If its raining I have to screw on the clear visors – then there are also visors tinted 50 % or 80%.
All visors exist in three different colours. Additionally, before every use tearing foils get mount to the visors, so that the drivers are able to remove the layers easily with one flick while driving 320km/h in case they are dirty or fogged up. Sven Krieter is in direct contact with every driver at the racetrack who wears a SCHUBERTH helmet. He observes the weather and prepares as required at least two or three different helmets before the race start. And also that is important for the aerodynamics: All helmets are tested and checked at our own wind tunnel.
Most important for the drivers are air circulation and the weight. In former times, the air was just blown against the forehead and the face. Nowadays the air is guided backwards along the top of the head and escapes through vent holes.
