TRW develops active seat belt presenter

TRW Automotive Holdings has developed a new, active seat belt technology which assists the driver to grasp the belt during the buckling up process. The system, known as TRW's active seat belt presenter, can help to support elderly or less mobile passengers, as well as act as a reminder to fasten the seat belt upon entering the vehicle.

RSS601 TRW Automotive Holdings has developed a new, active seat belt technology which assists the driver to grasp the belt during the buckling up process. The system, known as TRW's active seat belt presenter, can help to support elderly or less mobile passengers, as well as act as a reminder to fasten the seat belt upon entering the vehicle.

"Widely available statistics indicate an aging population globally and we believe that comfort functions such as our seat belt presenter are becoming increasingly important for this demographic,” says Uwe Class, senior engineering manager, global active restraint systems at TRW.

TRW's new seatbelt presenter is mounted directly on the height adjuster within the vehicle's B pillar. When the occupant is seated, the presenter, a small arm which rests within the B pillar, brings the belt forward to an 'easier to reach' position. As soon as the occupant takes the belt, the arm simply reverts to its original park position. TRW says the presenter can be integrated easily into the B pillar with no modifications required other than to the trim.

"The seat belt presenter can bring the belt forward up to 300mm depending on the vehicle,” says Class. “We are working closely with individual vehicle manufacturer customers to identify the optimum position for occupants to retrieve the belt and minimise any twisting action required as part of the buckling process."

    Driverless cars will have a detrimental effect on congestion and security while the road safety benefits can be achieved sooner and cheaper using ADAS, argues Colin Sowman. Many Governments are consulting about the introduction of driverless vehicles and even running trials. As 70% or 80% of crashes are caused by human error, the promise of a crash-free future of driverless, self-driving or autonomous vehicles (call them what you will) is alluring, as are the claims of reduced congestion and lower emissions

    Minnesota DoT has built one of the most intensive Active Traffic Management (ATM) systems on the road today. Like many ITS deployments, the state has gained benefits but also faces many challenges, as Pete Goldin reports. Smart Lanes is the brand name of Minnesota Department of Transportation’s (MnDoT) ATM system on I-35W in the Twin Cities Metro Area. The original system covered 16 miles of I-35W south of Minneapolis starting in 2009, and was extended by two miles in 2011. Additional ATM equipment was inst
