Vehicle temperature alarm for vehicle occupants and pets
First Claim
1. A vehicle interior temperature alarm system for activating an alarm at a selected cold temperature or selected heat temperature, comprising:
- a single housing having a forward facing wall and a rearward facing wall and side walls facing in different directions from the forward facing wall and the rearward facing wall, one of the side walls supporting a front vehicle seat facing scanning motion detector covering at least a front seat portion of the vehicle and the rearward facing wall supporting a separate rear vehicle seat facing scanning motion detector covering a rear seat of the vehicle, and the single housing having a temperature sensor, the single housing having a removable strap mount adapted to be mounted to a headrest on a seat inside of a vehicle, the temperature sensor being adjustable for detecting a selected cold threshold temperature and a selected heat threshold temperature;
an alarm inside of the vehicle, wherein a combination of occupant motion detected by at least one of the front vehicle seat or the rear vehicle seat scanning motion detectors inside of the vehicle, and either the selected heat threshold temperature or the selected cold threshold temperature is detected by the temperature sensor, activates the alarm; and
a battery power supply for the alarm system, with a low battery indicator.

Abstract
Systems, devices and methods of using motion detectors and temperature sensors inside vehicles for activating alarms to protect vehicle occupants that include babies, children, infirm, elderly and pets. Headrest mounted motion detector(s) and a temperature sensor detect both motion and selected temperatures to remotely transmit alarm signals to the vehicle horn that can play an SOS alarm. The detectors and temperature sensor can sound alarms when unsafe cold and warm interior vehicle temperatures are reached. Low battery indicators such as audible alarms, chirp sounds and lights can be used to indicate low battery power supplies.

11. A method of activating a temperature dependent alarm inside a vehicle, comprising the steps of:
-
providing a single housing having a forward facing wall and a rearward facing wall and side walls facing in different directions from the forward facing wall and the rearward facing wall; supporting a rear vehicle seat motion scanning detector from the rearward facing wall, for covering at least a rear seat portion of the vehicle; supporting a separate front vehicle seat motion scanning detector from at least one of the side walls covering a front seat in the vehicle; providing a temperature sensor in the single housing, which is adjustable for sensing between a selected cold temperature threshold and a selected heat temperature threshold; attaching by a removable strap mount the single housing to a headrest above a seat inside of the vehicle; supplying power from a battery supply to both the rear seat motion detector and the front seat motion detector and the temperature sensor; detecting motion of a vehicle occupant from at least one of the rear seat motion detector and the front seat motion detector, in combination with the selected cold temperature threshold or the selected heat temperature threshold sensed by the temperature sensor inside the vehicle; activating an alarm when both the motion and the selected cold temperature threshold or the selected heat temperature threshold have occurred over a selected time period; and indicating a low battery condition when the battery supply is running low. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
