Automotive and Racing Safety
Seat belts are an obvious example of webbings used in auto safety but there are myriad other uses. Nylon and polyester webbing are used a great deal in auto racing safety for a large variety of items. Racing harnesses restraining the driver have used nylon webbing for years, but since the death of Dale Earnhardt Polyester webbing is becoming more popular due to its increased strength, and lower rate of elongation under load. The nylon commercial type 9 webbing generally used in racing harnesses stretches approximately 20 to 30 percent of its initial length at 2500 lb (11.1 Kn) while Polyester only stretches 5 to 15 percent. Window nets to prevent objects from entering the driver compartment are constructed of polypropylene webbing, as are helmet nets used to reduce side loads to the head in Sprint cars. The HANS device uses webbing tethers to attach the helmet to the collar, and the Hutchens device is made almost entirely of webbing.

Famous quotes containing the words racing and/or safety:
“Upscale people are fixated with food simply because they are now able to eat so much of it without getting fat, and the reason they don’t get fat is that they maintain a profligate level of calorie expenditure. The very same people whose evenings begin with melted goat’s cheese ... get up at dawn to run, break for a mid-morning aerobics class, and watch the evening news while racing on a stationary bicycle.”
—Barbara Ehrenreich (b. 1941)
“An evident principle ... is the principle of justice to all peoples and nationalities, and their right to live on equal terms of liberty and safety with one another, whether they be strong or weak.”
—Woodrow Wilson (1856–1924)
