Airbag deployment and eye perforation by a tobacco pipe.

Airbags have been shown to reduce injuries and save the lives of car occupants in a crash. Like any protection system, airbags potentially introduce some new risks if no appropriate countermeasures are taken. A case of a relatively moderate frontal impact is described where the driver of an airbag-equipped car suffered a severe penetrating eye injury after the airbag deployed. Since the airbag fabric itself was excluded as an injury-producing structure, other objects such as eyeglasses, a wrist-watch, a bracelet, and a large finger ring had to be assessed. The investigation of the car interior as well as the morphologic details of the injuries to the eye and the face revealed that the most likely candidate for the injury was a tobacco pipe, which was probably being held in one hand and was broken apart by the deploying airbag and projected into the face of the driver. This case illustrates the hazard of having any rigid object between the occupant and the deploying airbag. The desirability of warning car occupants of the potential hazards which can result from today's protection systems is also discussed.
