Press release date: June 18, 2014

LIVONIA, Mich. -- TRW Automotive Holdings Corp. (NYSE: TRW), today announced that it is launching its next generation seat belt retractor - the Floating Spool 1 (FS1) - which offers reduced weight and smaller dimensions when compared with previous systems.  The global FS1 technology is starting production with several vehicle manufacturers in Asia, Europe, North America and South America during the second quarter of 2014.

In a crash scenario, most seat belt retractors use a lock pawl to hold the webbing in place. Instead, the new FS1 design with fewer components uses the forward movement of the occupant to apply force to the webbing, which then moves the spool, locking the retractor.  It offers a simpler, standardized component design that can be easily adapted to local market requirements at a highly competitive cost, and can be produced using fully automated or semi-automated manufacturing processes.

Aziz Canatar, global engineering director, TRW Seat Belt Systems, said: "Our new FS1 technology weighs approximately 15 percent less than the previous generation, making it a more environmentally friendly product that can help automobile manufacturers meet emissions and fuel economy targets. In addition, the smaller retractor offers significant packaging advantages and greater installation options."

The new retractor technology is suitable for front and rear seat applications using buckles and/or anchor pretensioners. The FS1 is available as a standard retractor without load limiter, but also with a constant load limiter using a standard torsion bar.

Both standard and reverse payout versions are available with the FS1. The sensor locking mechanism, with fewer moving parts, gives it excellent NVH characteristics. Optional functions include a child seat restraint feature, sensor blockout for folding seats and a noise dampening system.

Canatar added: "The design of the new FS1 offers many advantages related to weight, size and packaging flexibility. Standardized components and assembly options make it a truly cost-competitive, global technology. TRW believes FS1 is the retractor of choice to meet global market needs both now and in the future."
