There has thus been outlined, rather broadly, the more important features of the disclosure 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 disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.

FIG. 1 is a top view of a vehicle occupancy key locking safety device according to an embodiment of the disclosure.
FIG. 2 is a top rear side perspective view of an embodiment of the disclosure.
FIG. 3 is a partial top rear side perspective view of an embodiment of the disclosure.

FIG. 5 is a schematic view of an embodiment of the disclosure.



DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 5 thereof, a new safety device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 5, the vehicle occupancy key locking safety device 10 generally comprises a vehicle 12 having a plurality of non-driver seats 16 and an ignition 18. The ignition 18 is of the type dependent on a key 20 being turned between a run position 22 and an off position 24 to shut off the vehicle 12. Thus, the vehicle 12 remains running, including any air conditioning or heating systems activated, until the key 20 is turned from the run position 22 to the off position 24. Each non-driver seat 16 may be a respective rear seat 26 within the vehicle 12. There may be a single row of rear seats 26 in the vehicle 12 or the vehicle may be of the type having a plurality of rows, each comprising one or more rear seats 26. The vehicle 12 also is of the type having a battery 28 used to start an engine or initiate running of the vehicle 12.
Each of a plurality of sensors 30 is coupled to the vehicle 12 such that each sensor 30 detects occupancy of an associated one of the non-driver seats 16. Each sensor 30 is a pressure sensor 32 having a base 34 and a pressure sensitive button section 36. Apertured flanges 38 may extend from the base 34 to facilitate coupling of the sensor 30 within a bottom section 42 of the associated non-driver seat 16.
A key locking mechanism 44 is coupled to the ignition 18 of the vehicle 12. The key locking mechanism 44 inhibits turning of the key 20 to the off position 24 to shut off the vehicle 12 while the key locking mechanism 44 is actuated. The key locking mechanism 44 is operationally coupled to each sensor 30 such that the key locking mechanism 44 is actuated while any one non-driver seat 16 is occupied as detected by the associated sensor 30. The key locking mechanism 44 may provide a conventional mechanical obstruction to turning of the key 20.
A processor 50 is coupled to the vehicle 12. Each sensor 30 is communicatively coupled to the processor 50. The key locking mechanism 44 is operationally coupled to the processor 50 such that the key locking mechanism 44 is actuated by the processor 50. Thus, the key locking mechanism 44 may permit physical turning of the key 20 while preventing such turning from shutting off the vehicle 12. The processor 50 is electrically coupled to the battery 28. Each sensor 30 is electrically coupled to the battery 28 through the processor 50 and the key locking mechanism 44 is also electrically coupled to the battery 28 through the processor 50.
In use, the device 10 is passive in that it acts to prevent shutting off the vehicle 12 while occupancy of any non-driver seat 16 is detected. Thus, a driver cannot inadvertently leave a child or pet in the vehicle 12 unless the vehicle 12 remains running.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
