Suppliers develop rear-seat Airbag

Airbag suppliers, which have developed an array of airbags, side curtains and knee bolsters to protect front-seat occupants, are starting to design a new generation of airbags for rear-seat passengers.

TRW Automotive Holdings Corp. has unveiled two airbags, one mounted in the roof, and one in the back of the front seat, that could protect rear-seat passengers during a frontal collision.


The new airbags are likely to debut in Europe, which has mandated crash tests for a dummy the size of a 6-year-old in the rear seat starting in 2016, says Steve Peterson, TRW's North American director for occupant safety systems engineering.

"Europe is a little bit ahead of the U.S.," Peterson said. "We've got some customers in Europe that want to deploy a rear bag from the roof, and some from the front seat. We are studying this with several different customers."

'Bag in roof'

The Citroen C4 Cactus is equipped with a new roof-mounted passenger airbag technology. The new 'bag in roof' replaces the passenger airbag typically mounted in the instrument panel. Besides saving space, it will allow for improved interior design aesthetics, ergonomics and functionality as the instrument panel does not need to be designed around the conventional passenger airbag.



The airbag unit attaches to the roof above the windscreen. When it fires, instead of unfolding towards the occupant, the bag unfolds along the windscreen. This helps to restrain front seat passengers of varying shapes and sizes.

During a recent crashtest conducted by EuroNCAP the Citroen C4 Cactus scored 4 stars. The video of this crash test also shows how the roof-mounted passenger airbag deploys during the collision:


From an extrication-perspective the new ´bag in roof´ raises some concerns when it comes to cutting into the roof of the vehicle, for instance when relief cuts are set in order to flap the roof down on a side resting vehicle.

Similar to the passenger dashboard-mounted airbag the roof-mounted airbag consists of the folded airbag cushion, a gas diffusion channel and the airbag inflator. Airbag inflators should generally not be damaged during extrication evolutions, which makes it essential to know where airbag modules or remotely mounted inflators are mounted in the vehicle. Therefore, the Crash Recovery System will show the new airbag design and its location in the roof which will make it easy to identify the hazard zone and to avoid cutting into the airbag module.

Ford Mustang frontal airbag:


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
