How the 2015 Ford Mustang will save your kneesSat, 21 Jun 2014 11:00:00 EST
The 2015 Mustang is one of the most hotly anticipated vehicles of the moment, and Ford continues to leak out interesting little details about its newest pony car. The latest info doesn't have anything to do with its quarter-mile time or handling, but if any of that goes drastically wrong, the innovative new glovebox-mounted airbag may prevent passengers from knee injuries.
All variants of the 2015 Mustang get the active knee airbag as standard, and it's the first vehicle in Ford's lineup to receive the system. The setup is actually quite simple and ingenious. The glovebox is made from a plastic outer panel that is attached to the inner door. Sandwiched between them is this new injection-molded plastic bladder that folds flat when in use. If the passenger-side airbag deploys, the system springs into action to act as a cushion for your knees. Compared to a traditional knee airbag that has to fully inflate, this arrangement is 65 percent lighter and can use a 75 percent smaller inflator. It's also basically invisible when you look at the glovebox door.
Ford spokesperson Ed Saenz declined to tell Autoblog whether the system will appear in other vehicles in the Blue Oval's lineup but said, "We're considering other applications." Provided it's effective, the approach seems too simple not to make its way to other products. Scroll down to watch a video showing how the glovebox-mounted knee airbag works.
Ford Introduces Innovative Airbag Design on New 2015 Mustang
? Ford is introducing an all-new inflatable airbag restraint design that provides the front seat passenger in a Ford Mustang with knee airbag protection while significantly reducing system size and weight, enabling a roomier interior for more comfort
? Ford introduces the first passenger knee airbag system packaged inside the glove box door with 15 patents granted and more pending
? All-new Mustang has twice as many airbags, twice as many peripheral crash sensors and additional pretensioning safety belt technology compared to the outgoing model
DEARBORN, Mich., June 19, 2014 – A new airbag design debuting on the 2015 Ford Mustang raises the bar for passenger safety by providing inflatable restraint protection in a smaller, lighter package that also enables a roomier interior for more comfort.
The new airbag will be introduced later this year as part of a standard comprehensive safety system that includes a more robust package of sensors, safety belt anchor pretensioners, improved exterior lighting and double the total number of airbags on the all-new Mustang.
In the initial application of this technology, an inflatable plastic bladder is integrated into the glove box door and provides front passenger knee protection similar to a conventional knee airbag mounted under the instrument panel. Other applications for this unique and patented technology – which allows airbags to be placed in new locations inside the vehicle and provides more freedom to vehicle designers – are being considered.
"We provide a high level of safety, quality and design for our customers and their passengers," said Sean West, Ford restraints manager. "With this innovative airbag design, we have developed technology that provides protection for vehicle occupants while also reducing weight and enabling greater design flexibility."
To make the new knee airbag possible, Ford engineers developed and tested innovative materials and construction techniques. Unlike a traditional fabric airbag, the new system consists of a pliable, injection-molded plastic bladder sandwiched between the inner and outer glove box door panels. After an applicable vehicle impact is detected by the crash sensor system and classified, an inflator fills the bladder, extending the entire glove box outer door panel toward the front passenger's legs. Once deployed, the outer door helps to provide cushioning in a manner similar to a traditional knee airbag.
Since the glove box-integrated airbag extends straight out from the instrument panel, it doesn't have to travel as far as a conventional airbag, which deploys toward the floor before curving upward. Since the glovebox door distributes the impact load over a larger area than a traditional airbag, it is able to operate at a lower inflation pressure.
The resulting design is 65 percent lighter with an inflator that is approximately 75 percent smaller than a conventional knee airbag inflator, while providing comparable protection to the passenger. The improved packaging of the system is more discreet, with no visible seams or airbag cover. This has given designers more flexibility to move the dashboard closer to the windshield, enhancing the feeling of roominess in the cabin.
In developing the new Mustang passenger knee airbag, Ford has been granted 15 U.S. patents already, with more patents filed.
The active glove box knee airbag is among a number of technology features on the all-new Mustang, including:
? Eight airbags, twice as many as the current model. Along with the glove box knee airbag for front passenger, the new Mustang fastback and convertible have driver and passenger front and seat-mounted side airbags, as well as a driver knee airbag. The fastback adds two side curtain airbags, while the convertible gets a seat-mounted head airbag on each side
? Additional crash sensors are located on the front, sides and center of the car to control the deployment of airbags and safety belt pretensioners. The new Mustang now has two front sensors – two per side – and a roll rate sensor in the restraint control module, all of which contribute to a more adaptive safety system to protect occupants in different types of crashes
? Also new to Mustang are safety belt pretensioners added to the belt anchor side that further tighten the belt around front seat occupants, keeping them in a more secure spot early in the event of a crash
? Tri-bar signature lighting and high-intensity-discharge headlamps for improved visibility of the road ahead during nighttime driving
? Industry-exclusive Ford MyKey® allows parents to limit top speed and audio system volume, and to set limits to prevent the disabling of driver-assist features
"The new Mustang has increased ability to adapt safety systems to a variety of potential situations," said Jeff Rupp, Mustang safety systems manager. "For example, we've added new anchor-side safety belt pretensioning capability and a steering column that can adapt stiffness properties."
2015 Ford Mustang
The all-new Mustang is the most advanced version yet of the pony car. The sleek new design of Mustang fastback and convertible is backed up by world-class performance from a range of available engines, including a new turbocharged EcoBoost® 2.3-liter and an upgraded 5.0-liter V8 with more than 420 horsepower.
In addition to state-of-the-art connectivity systems, Mustang makes advanced driver-assist systems available – including track apps, launch control and more.
