TRW has unveiled its new ‘bag-in-roof’ airbag system which replaces passenger airbags typically mounted in the instrument panel.
The new airbag, says TRW, can help mitigate passenger injuries and can allow for improved interior design aesthetics and ergonomics, while saving space in the instrument panel.

By eliminating the need to package a passenger airbag in the instrument panel, TRW’s bag-in-roof design can significantly reduce development costs of the dashboard as there is no need to develop a specific ‘door’ that opens with the airbag deployment.
“Occupant safety systems are becoming increasingly versatile,” said TRW inflatable restraint systems engineering director Dirk Schultz. “With the increasing focus on reducing road fatalities we need to develop new ways to enhance the protection of occupants – one area of focus is the design and configuration of airbags.
“Studies have shown that such a technology provides styling flexibility for future vehicle interiors in combination with restraint performance.”
The airbag unit comprises a cushion and a gas generator which supplies the gas to the cushion in the event of an impact.
