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; and
an alarm inside of the vehicle, wherein a combination of occupant motion detected by at least one of the front vehicle seat and the rear vehicle seat scanning motion detectors inside of the vehicle, and the selected heat temperature or the selected cold temperature is detected by the temperature sensor which together activates the alarm.

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.

12. 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 in 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 between a selected cold temperature threshold and a selected heat temperature threshold; mounting by a removable strap mount, the single housing to a headrest above a seat inside of the vehicle; supplying power to the both the rear vehicle seat and the front vehicle seat motion scanning detectors and the temperature sensor; detecting motion of a vehicle occupant from at least one of the rear vehicle seat and the front vehicle seat motion scanning detectors, and the selected cold temperature or the selected heat temperature has been detected inside the vehicle; and activating an alarm when the motion from at least one of the rear vehicle seat and the front vehicle seat motion scanning detectors, and the selected cold temperature or the selected heat temperature have occurred over a selected time period. - View Dependent Claims (13, 14, 15, 16, 17)
