Abstract

An apparatus provides visible warning to a vehicle'"'"'s driver, other drivers and law enforcement when an vehicle'"'"'s occupant remains unbuckled in a car seat.

Claims

1. An apparatus for the notification and alert of drivers and law enforcement officials of the presence of an unsecured occupant of an automobile comprising:

(a) an occupant state detector for determining the presence of an unsecured individual disposed upon a car seat located within the automobile including;

(i) a latch state sensor for detecting the state of a seat belt latch of a seat belt associated with the car seat and capable of being activated by an unbuckled seat belt;

(ii) an occupant detector for detecting the presence of a individual seated within the car seat and activated if the seat is occupied; and

(iii) an alarm light visible from outside the vehicle and activated if the sensor is activated and the occupant detector is activated.

2. An apparatus for the notification and alert of drivers and law enforcement officials of the presence of an unsecured occupant of an automobile comprising:

(a) an occupant state detector for determining the presence of an unsecured individual disposed upon a car seat located within the automobile including;

(i) a latch state sensor for detecting the state of a seat belt latch of a seat belt associated with the car seat and capable of being activated by an unbuckled seat belt; and

(ii) an occupant detector for detecting the presence of a individual seated within the car seat; and

(iii) a control unit for processing signals generated by the latch state sensor and the occupant sensor, the control unit capable of determining and generating an alarm signal when during the presence of an “

OCCUPANT”

signal provided by the occupant detector there is lacking for at least a predetermined criteria of time a “

LATCH”

signal from the latch state sensor; and

(b) a power unit for supplying electrical power to the control unit.
