ABSTRACT:
A protection system providing a crash barrier for an occupant of a vehicle having a header when the vehicle is subjected to an impact force. The protection system comprises a pair of expandable bellows, a latch, a crash barrier, a sensor, and an expander responsive to operation of the sensor. The pair of spaced expandable bellows are adapted to be in a normally retracted stored relationship to the header of the vehicle. Each bellows has a first end affixed with respect to the vehicle on one side of the occupant and a second end expandably deployable to an opposite side of the occupant. The latch is adapted to be affixed with respect to the vehicle at the opposite side of the occupant to latchingly receive the second end of each bellows. The crash barrier has one portion adapted to be affixed with respect to the vehicle on the one side of the occupant and another portion attached to the second end of each bellows. The crash barrier is deployable with the second end of each bellows to the opposite side of the occupant. The sensor operates to sense when the vehicle is subjected to a high impact force and expands the bellows to deploy the crash barrier.
