Abstract

The child car seat safety alarm is an alarm system. The child car seat safety alarm is configured for use with a child safety seat and a driver'"'"'s seat. The child car seat safety alarm is configured to detect the weight of a first individual in the driver'"'"'s seat. The child car seat safety alarm is configured to detect the weight of a second individual in the child safety seat. If the child car seat safety alarm detects the weight of the second individual in the child safety seat but does not detect the weight of the first individual, the child car seat safety alarm initiates a plurality audio and visual alarms to indicate that the second individual remains in the child safety seat. The child car seat safety alarm comprises a beacon module and a child safety seat module.

Claims

1. A movable seat comprising:

a beacon module and a child safety seat module;

wherein the beacon module and the child safety seat form a wireless communication link;

wherein the movable seat is configured for use with a vehicle;

wherein the vehicle is further defined with a child safety seat and a driver'"'"'s seat;

wherein the beacon module installs in the driver'"'"'s seat of the vehicle;

wherein the child safety seat module installs in the child safety seat;

wherein the beacon module;

a) detects the weight of a first individual in the driver'"'"'s seat; and

, b) transmits a signal over the wireless communication link to the child safety seat module;

wherein the child safety seat module;

c) detects the weight of a second individual in the child safety seat;

d) detects the transmitted signal from the beacon module; and

;

e) generates the audible and visual alarm;

wherein if the child seat module detects the weight of the second individual in the child safety seat but does not detect the weight of the first individual, the child seat module initiates a plurality audio and visual alarms to indicate that the second individual remains in the child safety seat;

wherein the beacon module comprises a tee housing and a beacon circuit;

wherein the tee housing contains the beacon circuit;

wherein the tee housing mounts in the driver'"'"'s seat of the vehicle;

wherein the tee housing is a hollow structure;

wherein the tee housing mounts in the driver'"'"'s seat such that the hollow interior volume of the tee housing decreases when the first individual is in the driver'"'"'s seat.

2. The movable seat according to claim 1

wherein the tee housing further comprises a circuit cylinder and a tee cylinder;

wherein the tee cylinder is a tee shaped structure;

wherein the tee cylinder installs telescopically into the circuit cylinder;

wherein the circuit cylinder is a capped tube;

wherein the circuit cylinder contains the beacon circuit.

3. The movable seat according to claim 2

wherein the tee cylinder further comprises a cross cylinder and a cantilever cylinder;

wherein the cross cylinder forms the cross prism of the tee cylinder;

wherein the cantilever cylinder forms the cantilever prism of the tee cylinder;

wherein the tee housing installs in the driver'"'"'s seat of the vehicle such that the back of the first individual presses against the cross cylinder of the tee cylinder.

4. The movable seat according to claim 3

wherein the circuit cylinder is a hollow first prism;

wherein the circuit cylinder is further defined with an inner dimension and an open end;

wherein the cantilever cylinder is a second prism;

wherein the cantilever cylinder that is further defined with an outer dimension;

wherein the circuit cylinder and the cantilever cylinder are geometrically similar;

wherein the outer dimension of the cantilever cylinder is less than the inner dimension of the circuit cylinder such that the cantilever cylinder inserts into the open end of the circuit cylinder in a telescopic manner;

wherein the position of the cantilever cylinder within the circuit cylinder determines whether the driver'"'"'s seat is occupied.

5. The movable seat according to claim 4

wherein the beacon circuit is an electric circuit;

wherein the beacon circuit detects the weight of the first individual in the driver'"'"'s seat;

wherein on detection of the weight of the first individual, the beacon circuit initiates the transmission of the signal over the wireless communication link.

6. The movable seat according to claim 5

wherein the beacon circuit further comprises a beacon power source, a beacon pressure switch, and a transmitter;

wherein the beacon power source, the beacon pressure switch and the transmitter are electrically interconnected.

7. The movable seat according to claim 6

wherein the beacon power source provides electrical energy for the operation of the transmitter;

wherein the transmitter is a radio frequency transmitting circuit that generates the signal transmitted by the beacon module;

wherein the beacon power source, the beacon pressure switch, and the transmitter form a series circuit such that the closure of the beacon pressure switch provides the power that initiates the operation of the transmitter.

8. The movable seat according to claim 7 wherein the free end of the cantilever cylinder attaches to the beacon pressure switch of the beacon circuit such that the weight of the first individual in the driver'"'"'s seat will actuate the beacon pressure switch into a closed position.

9. The movable seat according to claim 8

wherein the child safety seat module comprises a CSS housing and a CSS circuit;

wherein the CSS housing contains the CSS circuit;

wherein the CSS housing is a rectangular block structure placed on the child safety seat.

10. The movable seat according to claim 9

wherein the CSS circuit comprises a logic module, a communication module, a CSS power source, a CSS pressure switch, a plurality of LEDs, one or more speakers, a limit resistor, and the wireless communication link;

wherein the CSS power source provides electrical energy for the balance of the CSS circuit;

wherein the logic module, the communication module, the CSS power source, the CSS pressure switch, the plurality of LEDs, the one or more speakers, and the limit resistor are electrically interconnected.

11. The movable seat according to claim 10

wherein the logic module is a programmable electronic device

wherein the communication module is a wireless electronic communication device;

wherein the communication module establishes the wireless communication link between the CSS circuit and the transmitter of the beacon circuit.

12. The movable seat according to claim 11

wherein the CSS pressure switch physically attaches to the bench of the child safety seat;

wherein the CSS pressure switch is actuated when the weight of the second individual is placed in the child safety seat.

13. The movable seat according to claim 12 wherein the CSS pressure switch is placed in series between the CSS power source and the balance of the CSS circuit such that the closure of the CSS pressure switch provides the power that initiates the operation of the CSS circuit.

14. The movable seat according to claim 13

wherein the plurality of LEDs generate visible illumination;

wherein the illumination of the plurality of LEDs is controlled by the logic module.

15. The movable seat according to claim 14

wherein the limit resistor is a resistor placed in series between the plurality of LEDs and the logic module;
