Mercedes-Benz ESF Safety Car: Better, Smarter Airbags!

Last summer we briefly about the Mercedes-Benz experimental safety concept including its remarkable under-car which deploys only a crash to help slow it

It’s a 2009 Mercedes-Benz Hybrid full-size luxury that’s been fitted several new and experimental devices to the car’s passive safety an accident.

Almost all of the technology will make its way into cars at some point.

First since 1974

we spent two hours interviewing manager Michael Fehring and all over the car, which was to revive the company’s long of high-tech safety prototypes, since 1974.

Some of the aren’t particularly visible, automatic headlights that the brightness of a partial high to compensate for oncoming vehicles.

But the notable thing about the ESF may be its use of technology in new and different ways. Not does it have a full of airbags, plus some new it uses gas cylinders to inflate steel door beams and a bag under the car.

Some highlights:

Looking at ways to reduce the of the car, the ESF team created a new of side-intrusion beam inside the skin. Current beams fit within the door skin, they are heavily engineered to be within a very narrow

The startling innovation here was to an inflatable steel beam, the same gas cylinder that current thorax airbags. By the beam’s diameter as much as 2 the beam becomes structurally using much lighter of steel.

The inflation is triggered by side-looking sensors, part of Pre-Safe an all-around accident detection Only 20 to 30 milliseconds is needed to the beam, which bulges out the skin significantly—unimportant if a side is pending.

According to Fehring, of the four new inflatable beams was 0.5 (1.1 pound) lighter the current design, cutting 5 pounds of total vehicle

While front-passenger are now standard in new cars, they’re than perfect. Unlike the seat, where the need to keeps the driver a predictable from the steering wheel, can adjust their seats far or aft—and they do.

The ESF team to make the passenger airbag by using the seat position to control how much the bag inflates. straps inside the bag control its keeping it smaller when the is far forward, but letting it fully if the seat is back.

And this appears to be one ESF innovation close to showing up in Mercedes-Benz Although he wouldn’t say when, said the size-adaptive airbag come very quickly production cars.

An even innovation is adjustment for the passenger’s based on a seat-compression sensor, by or closing a supplemental vent in the Heavier passengers need bags, so the vent stays lighter riders are cushioned by a bag whose gas escapes more through the open secondary
