Automatic emergency signal means for vehicles
First Claim
1. An automatic emergency signal means for vehicles comprising:
- a casing mounted in a vehicle and having a groove longitudinally recessed in said casing and defining a starting position in a rear portion in said casing and a target position in a front portion in said casing;
a movable weight movable in said groove in said casing;
a restoring lever pivotally mounted in said casing resiliently contacting said movable weight for normally biasing said weight towards the starting position in said casing;
a sensor provided in said casing at said target position for sensing a trigger signal when the weight is forwardly moved to approximate said sensor due to arm inertia of the weight upon an emergency brake of the vehicle;
an amplifier electrically connected with said sensor for amplifying said trigger signal as output from said sensor; and
a controller electrically connected to said amplifier for receiving and treating said trigger signal far controlling on and off of at least a warning light electrically connected to said controller, said controller electrically connected to a power source far powering said controller;
whereby upon an emergency brake of the vehicle, said movable weight is forwardly moved to sense said sensor to trigger said controller for lighting up said warning light for alerting a following vehicle.
