Alpinestars touts its Tech-Air as the world’s first self-contained street airbag system designed to function without the need for sensors to be fitted to the motorcycle. This eliminates the need for any kind of installation or pairing with a specific bike. All the rider has to do is zip up their jacket and the system is activated.
An LED display located on the sleeve provides visual confirmation the system is active and displays the battery’s charging level. When fully charged, its battery pack should be good for 25 hours of continuous use, with Alpinestars adding that one hour of charging is sufficient for four hours of riding time.
The algorithm of the street version has been optimized to identify all possible danger situations, including low- and high-side collisions. It even detects accidents that occur when the motorcycle is stationary, such as a rear impact while waiting at the traffic lights, for example.
Depending on the accident type, the system will typically detect an impact within 30 to 60 milliseconds and deploy in the subsequent 25 ms, promising protection to the chest, kidney areas, back and shoulders.
The BMW Motorrad jacket, which will carry branding of both BMW and Alpinestars and come in male and female versions, is set to make its public debut later this year.
The following video shows the Alpinestars Tech-Air street airbag system in action and outlines its functions.
