Abstract
In an apparatus for protecting passengers of a motor vehicle from being injured in the event a collision of the vehicle by utilizing an air cushion bag which is inflated by an electric actuator device operative in response to the collision, an apparatus for recording erroneous inflation of the protection air bag comprises a circuit for detecting the application of electric energy to the actuator device and for determining if such application of electric energy is made through a collision sensing switch which serves to connect the actuator device to an electric energy source upon an actual collision. When the application of the electric energy to the actuator device without the aid of the collision sensing switch is detected upon the inflation of the air bag, such inflation is regarded as the one due to erroneous operation for some reason other than an actual collision and a signal indicative of such inflation is recorded.
