Abstract
A restraint system for helping to protect an occupant of a vehicle having a roof and a cabin with a seat for the occupant includes an airbag mounted to the vehicle roof. The airbag has a stored condition and is inflatable to a deployed condition having a front-facing occupant receiving portion and an opposite rear-facing portion facing away from the occupant. The airbag has one or more connections with the vehicle roof, with the airbag and the connections being configured such that the roof serves as a reaction surface for supporting the airbag against movement in response to a forward moving occupant impacting the occupant receiving portion. The system is non-reliant on the rear-facing portion of the airbag engaging and using vehicle structure as a reaction surface for supporting the airbag against movement in response to the impacting occupant.
