TURN ACTUATED ALARM SYSTEM FOR AUTOMOTIVE VEHICLES
First Claim
Patent Images
1. A vehicle turn alarm in combination with a vehicle having a conventional turn signal actuator movable between a normally deenergized condition and an energized condition comprising:
- a turn sensor mounted on said vehicle so as to be responsive to vehicle sideWise tilting and sideward centrifugal forces imposed on the vehicle body;
an alarm connected to said sensor in an alarm activation circuit for selective activation when said sensor senses vehicle tilting or sideward centrifugal forces of at least a predetermined permissible upper level;
means for selectively deactivating said alarm following activation thereof by said sensor, and means for maintaining said alarm deactivated until abatement of said forces to a level specified hereinbelow, said deactivating and maintaining means being operatively connected to said turn signal actuator so that movement of said actuator from said normally deenergized condition to an energized condition effects deactivation, by operating a relay to open normally closed relay contacts in the alarm activation circuit, and maintains deactivation by closing normally open relay contacts as described hereinbelow, other normally open contacts connected to said sensor so as to close upon response of said sensor to vehicle tilting or sideward centrifugal forces of a value substantially less than said predetermined permissible upper level, said other normally open contacts being connected through said normally open relay contacts to the coil of the relay in a circuit which, when closed, maintains said relay operated, and means to re-open said other normally open contacts upon response of said sensor to abatement of said vehicle tilting or sideward centrifugal forces to a level below said value substantially less than said permissible upper level.

Abstract
A centrifugally and/or tilt-actuated switch is provided on an automobile which is actuated when a vehicle travels around a curve at a speed in excess of the safe speed on the curve to operate an alarm and alert the driver that he is moving at an excessive rate of speed for that curve. The conventional turn signal mechanism on the automobile when actuated deactivates the alarm so that the alarm will not operate when the automobile is going around a sharp corner in a city and will remain deactivated until the car has returned to normal operation. If the turn indicator is not actuated prior to turning a corner, the alarm will sound to advise the driver that he has not properly actuated the turn signals.

-
2. The arrangement of claim 1 wherein said sensor comprises a centrifugal tilt switch containing passages partially filled with mercury, and said contacts connected to said sensor include wire leads positioned in said passages above the normal horizontal level of mercury contained therein.
