Editing Webbing (section)

=== Automotive and racing safety ===

[[Seat belt]]s 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. [[seat belt|Racing harnesses]] restraining the driver have used nylon webbing for years, but since the death of [[Dale Earnhardt#Death|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 {{cvt|2500|lbf|kN|order=flip}} 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 car racing|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.
