The Indianapolis 500, commonly called Indy 500, is a 500-mile automobile race which has become the largest single-day spectator sporting event in the world. Since its meager beginnings in 1909, people have flocked to the track in record numbers to watch the high-speed thrills. On May 30, 1941, George “Joie” Chitwood readied his cigar-shaped racecar, the Blue Crown Spark Plug Special, for the Indianapolis 500. During qualifying, Joie bounced around the track in his racecar and had a hard time keeping his foot on the accelerator. Out of necessity, Joie used a simple strap to fix the problem. The other drivers objected to the strap because they thought it was dangerous. The heads of the AAA Drivers Association agreed and refused to allow Joie to use the strap. They only relented when Joie promised to release the strap if he thought he was going to crash. Keep in mind that the cars traveled more than 100 miles per hour. Joie did not crash that day. He came in 14th place and won $620. (The first-place winner, Floyd Davis, received $29,200.) Joie believed that using the strap helped his performance in the 1941 Indy 500, but the other drivers remained skeptical.
For decades, the general public remained skeptical as well. Carmakers often adopt equipment designed for racing cars on their vehicles. In 1949, now defunct carmaker Nash Motors offered this strap on about 40,000 of their Airflyte and Ambassador models, but over 39,000 of them were removed by dealerships at the request of the owners. In 1955, Ford offered it as an option on their vehicles, but less than 2% of buyers chose the strap. In 1958, Saab became the first carmaker to include the strap as part of their standard equipment.
Although he had nothing to do with its invention, Joie Chitwood made history that day in May 1941 because he was the first driver to wear the strap in the Indy 500. Today, all race car drivers are required to wear one. It has also become a requirement in all automobiles. At that time, the common misperception was that people were safer in a car accident if they were thrown from the wreck rather than behind held inside the vehicle. They called the strap safety belts, but we know this strap as the seat belt.
