Nov. 29, 2011—TRW Automotive Holdings Corp., a supplier of automotive safety systems, on Tuesday unveiled its dual contour passenger airbag, which it calls the next generation of adaptive frontal passenger airbags.

TRW said the dual contour passenger airbag uses sensor inputs to adjust both the airbag pressure and size to help tailor protection according to occupant size and other variables of a crash. The airbag uses a tether activation unit that presents the right size and shape of the bag based on the particular crash variables.

The dual contour passenger airbag will be ready for production by 2013, according to TRW.

"Adaptive occupant safety technologies began with the introduction of dual stage inflators over a decade ago and have progressed to include not only factors such as deployment force, but also the bag geometry, stiffness and shape as the bag deploys,” said Norbert Kagerer, vice president of engineering for TRW's Occupant Safety Systems business. “TRW's next generation adaptive airbags combine all of these elements to help enhance the safety of occupants according to their size, the speed and force of the crash, occupant position, belted versus unbelted and more.”

Livonia, Mich.-based TRW Automotive Holdings Corp. operates in 26 countries and employs more than 60,000 people worldwide. The company’s products include integrated vehicle control and driver assist systems, braking systems, steering systems, suspension systems, occupant safety systems, electronics, engine components, fastening systems and aftermarket replacement parts and services.
