Ford patented a unique airbag for rear seats

The patented rear seat airbag is a substantially `U` shape to encompass both the front and rear sides of rear seat occupants when the rear seat airbag is deployed. The rear airbag is stored within a ceiling lining above a rear passenger cabin section.

The airbag deployment system gathers vehicle state information, analyzes the vehicle state information, determines whether to deploy one or more airbags, and then controls the deployment of the rear airbag.
