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.

A vehicle with a pet protection function includes a pet guard body, a first air-bag device, and a controller. The pet guard body is disposed in a vehicle compartment of the vehicle on which a pet is to be loaded in such a manner that the pet guard body partitions a vehicle compartment into a front portion and a rear portion. The first air-bag device is configured to be deployed behind the pet guard body. The controller is configured to deploy the first air-bag device upon contact of the vehicle.

An apparatus for helping to protect an occupant of a vehicle includes an airbag configured to inflate and deploy away from a vehicle roof toward a vehicle seat. The airbag includes a base portion configured to be connected to the vehicle roof and a cushion portion in fluid communication with the base portion. The cushion portion extends from the base portion toward the vehicle seat to an inflated and deployed condition in which the cushion portion is configured to receive and cushion an occupant seated on the vehicle seat. The apparatus also includes a deployment pocket for initially restricting the deployment of the cushion portion without restricting the base portion.

A roof airbag for a vehicle longitudinally extends along a length between first and second longitudinal ends and laterally extends along a width between first and second lateral sides. An inlet for receiving inflation gases is provided at the first longitudinal end. A plenum is in fluid communication with the inlet for receiving the inflation gases from the inlet. The roof airbag includes a plurality of primary inflatable chambers, each primary inflatable chamber in fluid communication with the plenum to receive inflation gases from the plenum. A plurality of secondary inflatable chambers is in indirect fluid communication with the plenum to receive inflation gases indirectly from the plenum through the plurality of primary inflatable chambers. The primary inflatable chambers of the plurality of primary inflatable chambers are arranged to first drive deployment of the airbag and subsequently inflate the second inflatable chambers of the plurality of second inflatable chambers to tension the airbag in the lateral direction. The primary and secondary inflatable chambers cooperate to provide a barrier between occupants of the vehicle and the roof frame.

A motor vehicle has a passenger compartment for at least one vehicle user and has at least one sensor device for detecting a location of the vehicle user in the passenger compartment. At least one retaining device is used to fix the vehicle user in his/her location. A control device is provided to activate the at least one retaining device according to a signal of at least one impact sensor of the motor vehicle. The at least one retaining device is designed to fix the vehicle user in a location in the passenger compartment different from a vehicle seat of the motor vehicle. A method operates such a motor vehicle.

An occupant protection system for a vehicle may include an expandable curtain and/or an expandable bladder configured to be expanded from a stowed state to a deployed state. The system may also include a transverse ceiling trim panel and one or more side ceiling trim panels configured to be coupled to a ceiling of the vehicle, with the transverse ceiling trim panel extending substantially transversely with respect to the one or more side ceiling trim panels. Portions of the ceiling trim panels may be configured to deflect and allow expansion of the expandable curtain and/or the expandable bladder to the deployed state. The system may also include a deployment controller and one or more inflators configured to cause deployment of the expandable curtain at a first time and deployment of the expandable bladder at a second time after the first time.
