<p>PURPOSE: To improve safety by a method wherein when a large impact is imparted to an automobile, an acceleration sensor is actuated to inflate a balloon and a solenoid valve or the like of a door lock device is actuated to automatically release the lock. CONSTITUTION: When an automobile comes into collision and abruptly stops, a signal of an acceleration sensor 1 causes a balloon before a driver's seat to inflate, protecting a driver. At that moment, a solenoid valve or the like of an automatic locking device 3 is actuated to automatically release automatic locking. Next, in the case of a manual locking, a solenoid valve for release is provided so that the solenoid valve is actuated upon a signal of the sensor 1 to release manual locking. Consequently, a door may not be cut by a cutting machine and people in the automobile can be rapidly rescued.</p> |
