Abstract
Abstract A novel medical appliance is disclosed comprising an inflatable cervical collar adapted to be disposed about the neck of a wearer who may be an occupant of a motor vehicle, for example. A source of compressed gas is connected to the inflatable collar, and triggering means are associated with the compressed gas source for inflating the collar upon the occurence of an impact to the vehicle, such as a rear-end collision. When the collar is inflated, rotation of the neck of the wearer relative to the torso is substantially reduced or prevented, thus preventing a whiplash-like head or neck injury.
