Central Airbag for Small and Compact Vehicles
Airbag Adds Stability Across the Seat
How is a 'transverse' setup different from a traditional CeAB setup? The conventional CeAB cushion uses the center console as a support element when it inflates. It is designed to deploy two chambers of the airbag to provide maximum 'lateral retention' up to head height.
However, many small and compact cars do not have a pronounced center console. Unlike larger vehicle classes, the narrow space between the driver and passenger seats in small and compact cars many times can only accommodate flat storage compartments or cupholders, if at all, making it more difficult to stabilize a central bag. ZF engineers developed an innovative, eponymous seat anchorage for their new transverse (center) airbag. The airbag fabric has a third anchorage point that extends right into the upper 'head chamber'.
On the seat, the airbag is also secured to the top of the backrest frame at two points. This optimized integration of the airbag into the seat marks a major difference from today's concepts on the market, providing numerous advantages and possibilities.
