ABSTRACT:
A vehicle tilt alarm system including a tilt angle responsive switch having a pendulum that can swing to make contact with conductive bolts provided on either side of the pendulum's pivot point. The amount of the protrusion of the bolts into the pendulum housing can be adjusted, thereby allowing the user to set the angle of vehicle tilt at which the switch will activate the alarm system. The switch is incorporated in an circuit including an alarm device such as a buzzer or flashing light. The alarm system is mounted on a vehicle whereby the tilting of the vehicle past a predetermined angle will activate the alarm system, thus informing the vehicle operator that the vehicle is dangerously close to rolling over.
