A restraint system (10) for helping to protect an occupant (60) of a vehicle (20) having a seat (50) for the occupant (60) includes a primary airbag (70) having a stored condition within the roof (32) and being inflatable to a deployed condition extending into the cabin (40) on a first side of the seat (50). A support airbag (76) has a stored condition within the roof (32) and is inflatable to a deployed condition on a second side of the seat (50) opposite the first side. Tethers (120) connect the primary airbag (70) and the support airbag (76) such that occupant (60) penetration into the primary airbag (70) pulls the support airbag (76) into engagement with the seat (50).

A vehicle airbag system includes an airbag module, a seat detector, and an electronic controller. The airbag module has an airbag that is configured to be movably mounted to a vehicle roof structure. The seat detector detects a position of a vehicle seat. The electronic controller is in communication with the airbag module and the seat detector. The controller controls the airbag module to inflate the airbag in a predetermined direction based on detected position of the vehicle seat by the seat detector.

Proposed is a roof airbag that is disposed at the roof of a vehicle and is deployed into an interior space of the vehicle. A bracket is provided to the roof. An inflator is connected to the bracket and configured to discharge an inflation gas when operated. An airbag cushion is provided to an airbag cover connected to the bracket in a foldable way and deployed into an interior space of the vehicle by the inflation gas supplied by the inflator. A tether is configured such that one end thereof is fixed to the roof side, and the other end of which is connected to the airbag cushion. The tether supports the airbag cushion so that, when the airbag cushion is deployed, the airbag cushion is deployed toward a seat.

A vehicle detects a rotation angle of a seat, controls activation of a first type of roof airbag module provided in a central portion of a headlining and located at a side of the seat when the detected rotation angle of the seat is greater than a first reference angle and less than or equal to a second reference angle, controls activation of the first type of roof airbag module and a second type of roof airbag module provided in the central portion of the headlining and provided at a rear of the seat when the detected rotation angle of the seat is greater than the second reference angle and less than or equal to a third reference angle, determines whether a collision with an obstacle has occurred during traveling, and deploys and expands the activated airbag module when determining that the collision with the obstacle has occurred.

A roof airbag for vehicles is proposed. The roof airbag includes: a main chamber configured to be deployed as gas is introduced therein through a diffuser; an overlap chamber into which the gas is introduced and configured to be deployed into a shape that overlaps the main chamber around the diffuser; and a support chamber into which the gas is introduced and configured to be deployed while overlapping a roof frame.
