TRW Automotive Holdings Corp. has begun production of active and passive safety systems and components in China for the Audi A4, built at First Automotive Works. TRW FAWER Automobile Safety Systems Co., Ltd. (TFASS), TRW's joint venture with the FAW Group, supplies steering wheels, driver-side airbag modules and side-impact airbag modules. Active safety components for this model such as rear brake calipers and brake boosters are supplied from TRW Lucas Varity Langzhong Brake Co., Ltd. (LVLB) in Langfang, China.
Earlier this year, TRW began production of safety systems and components for the Audi A6, to which TFASS also supplies steering wheels and driver-side and curtain airbag modules.
Among other TRW components, the A4 and A6 feature driver side dual-stage airbag inflators that provide varying air bag inflation levels to match deployment to variables including crash severity, seat belt usage, occupant position and weight.
