A vehicle includes a vehicle body defining a moonroof opening and a moonroof. The moonroof is moveably supported by the body and is moveable relative to the moonroof opening between an open position and a closed position. An airbag is mounted to the vehicle body. An inflator is in fluid communication with the airbag. A pyrotechnic device is operatively connected to the airbag to pull the airbag across the moonroof opening.

During a rollover situation there are possibilities of passenger head hitting the roof of the vehicle causing injury depending upon the passenger's height, head room, vertical and angular momentum where only side and curtain airbags cannot provide a complete head and neck protection. Comprehensive Roof Airbags (CRA) are integrated or installed internally and externally between, through and across the top of windshield, top of the roll over protection bars, head liner, roof rails, top of A, B and C pillars particularly works in roll over situation and deployed to cover the area with airbags on either one or more or combinations of inside headliner, outside rooftop and over the top of occupants head according to configurations and type of the vehicles thereby forming a protective layer to prevent or reduce the severity of head hitting the roof top in closed top vehicles and head hitting the road surface and debris in case open top vehicle ultimately to protect the passengers all to avoid or mitigate the head, neck and spine injury.

A roof-mounted energy absorbing countermeasure system for use in a vehicle is provided. In one example, the system may include an impact detection module configured to detect whether a vehicle has experienced an impact and generate an impact detection signal in response thereto. The system may also include a countermeasure disposed between an outer roof panel of the vehicle and an inner roof panel of the vehicle. The outer roof panel and the inner roof panel may be separated by a first distance in a pre-impact state. The countermeasure may eb configured to deploy, in response to generation of the impact detection signal, so as to cause at least a portion of the outer roof panel and at least a portion of the inner roof panel to be separated by a second distance that is greater than the first distance.

Systems for providing for an external vehicle airbag to mitigate the negative effects of vehicle rollover are described. In an exemplary implementation, one or more airbags are disposed inside the roof rails attached to a vehicle roof. In the event of a vehicle rollover, the airbags will deploy and extend downward along the sides of the vehicle. The airbags may be held in desirable deployed position by one or more elastic tethers.

An assembly includes a housing. The assembly includes an optical sensor supported within the housing. The assembly includes an airbag supported within the housing and deployable from a stowed position internal of the housing to an inflated position external of the housing. The airbag in the inflated position adjacent the optical sensor.

A control unit includes a communication module configured to receive a switch state configuration signal, which includes a configuration request for the switch state of the anti-rollover function suppression switch. The control unit further includes a judgment module configured to judge a validity of the switch state configuration signal, and a control module configured to control an ignition circuit associated with the anti-rollover function according to the switch state requested to be configured in the switch state configuration signal when it is determined that the switch state configuration signal is valid.
