ABSTRACT:
A pre-impact alarm apparatus which is adapted to signal the driver of a motor vehicle that obstacles exist in the path of the car while said car is backing up. The pre-impact alarm apparatus has a flexible sensing bar to be installed at a rear cover of a car which generates a signal that activates a buzzer to warn the driver when making contact with an obstacle, therefore improving upon the infrared alarm apparatus which can not warn the driver when the car is approaching an obstacle at an angle.
