Abstract

The electronic system for monitoring the occupancy of a vehicle seat to alert of an abandoned child includes a pressure sensing pad, that is placed atop a vehicle seat under an infant or child safety car seat and control module that interacts with a wireless device or FOB. When the pressure pad senses the weight of an infant or child on the vehicle seat, but the control module fails to detect the physical presence of the FOB within a predetermined range, the control module signals an alarm.

Claims

1. :

In a vehicle having a seat and safety restraints, an electrical system for externally indicating the occupancy status of the seat comprising;

a wireless device adapted to by carried by a user;

an alarm;

a pressure sensitive pad adapted to overly the vehicle seat for detecting the weight of an infant or child;

control unit operatively connected to the pad for activating the alarm when pressure pad detects the presence of an infant or child seated thereon and the wireless device is physically outside a predetermined range from the control unit.

2. :

The system of claim 1 wherein the control unit and wireless device each include proximity detection circuitry that generates a signal when the wireless device is outside a predetermined range from the control unit.

3. :

In a vehicle having a seat and safety restraints, an electrical system for externally indicating the occupancy status of the seat and the status of the safety restraints comprising;

a wireless device adapted to be carried by a user;

an alarm;

a buckle assembly adapted to be mounted to the safety restraints and having a first connector part and a second connector part, the buckle assembly generating a occupancy signal when the first connector part is couple to the second connector part,

a control unit responsive to the occupancy signal from the buckle assembly and the proximity of the wireless device to the control unit for activating the alarm when the wireless device is physically outside a predetermined range from the control unit.

4. :

The system of claim 3 wherein the first connector part includes a power supply and second connector part includes a transmitter to generating the signal.

5. :

The system of claim 3 wherein the occupancy signal is a wireless signal received by the control unit.

6. :

The system of claim 3 wherein the control unit and wireless device each include proximity detection circuitry that generates a signal when the wireless device is outside a predetermined range from the control unit.
