Designers study physical characteristics to optimize the user’s safety, health, comfort and performance. Physiological problems occur when the body is required to do too much work, to work awkwardly or to work under bad environmental conditions. Fatigue results from most work. Ergonomists assess physical work by measuring oxygen breathed, heart rate change etc, this interesting article from Core77 explores the Ergonomic considerations when designing a Formula 1 racing drivers helmet.
In addition to the pull-off strips, there is an impressive investment of design and materials science in the modern-day F1 helmet. First off they’re freakishly light, weighing just 1250 grams (under three pounds). This is to avoid burdening the driver with an extra-heavy head as they can experience as much as five G’s while cornering and braking.
Small vents are designed to allow airflow into the helmet. As it’s the driver’s only source of fresh air, there are filters in place to keep out brake dust, splashes of motor oil and the like.
The rest of the helmet, though, is designed to channel air around it, making it as aerodynamic as possible. F1 cars are traveling at such speeds that an overly wind-resistant design would snap the driver’s head backwards.
Alongside the chin-mounted comms microphone you’d expect is something more surprising: An in-helmet drinking straw that leads to the driver’s beverage of choice. A handy button on the steering wheel lets the liquid start flowing.
