ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to warning systems and more particularly pertains to a new warning system for fulfilling the need for an electronic reminder system that would help prevent parents from leaving children in vehicles unattended.
2. Description of the Prior Art
The use of warning systems is known in the prior art. U.S. Pat. No. 5,793,291 describes a child alert system for automobiles for detecting the presence of a person locked in a parked automobile. Another type of warning system is U.S. Pat. No. 5,949,340 describing a warning system for detecting presence of a child in an infant seat. U.S. Pat. No. 5,680,096 describes a process and apparatus for monitoring a vehicle interior. U.S. Pat. No. 6,028,509 describes a voice activated vehicle alarm system for the interior of a vehicle utilizing a temperature sensor measuring the interior temperature of a vehicle and producing a signal when a certain level of temperature is reached. U.S. Pat. No. Des. 411,375 describes an ornamental design for a combined child bed and safety seat for an automobile. U.S. Pat. No. 5,260,684 describes a warning system for a child's restraining seat for use in a passenger vehicle.
While these devices fulfill their respective, particular objectives and requirements, the need remains for a system that integrates with an existing vehicles security system for alerting you that your child is in the back seat of the vehicle.
SUMMARY OF THE INVENTION
The present invention meets the needs presented above by integrating with an existing vehicles electrical and security systems.
Another object of the present invention is to provide a new warning system that would remind parents to always take their children with them, so as to prevent heat stroke, potential abductions, and children working the vehicle controls that might otherwise cause accidents.
Still another object of the present invention is to provide a new warning system that would utilize dual sensors and detectors to prevent false triggering.
To this end, the present invention generally comprises a warning system for detecting the presence of a child in a vehicle. The vehicle has a front seat area, a rear seat area, and an interior. The vehicle has an electronics system. The system comprises a plurality of pressure sensors each removably positioned selectively under one or both of the front and rear seat areas such that pressure on one of the seat areas actuates an associated one of the pressure sensors. A control is electrically coupled to an electrical power supply and is electrically coupled to each of the pressure sensors. The control is selectively coupled to the electric system of the vehicle such that the processor may detect when the vehicle is turned off. An alarm is operationally coupled to the control and emits an audible sound when any of the pressure sensors sense pressure. The control is turned on when the vehicle is turned off.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the invention, along with the various features of novelty, which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
