ABSTRACT:
An alarm includes a pressure-actuated sensor positional beneath the seat liner of a vehicle child seat. The sensor includes a plastic enclosure positioned thereabout for shielding the sensor from foreign elements. A speaker is coupled to the sensor and is attachable to an outer surface of the child seat. A push button switch is coupled to the sensor and the speaker, and is attachable to a vehicle door. The switch includes a female receptacle and a male plug mateable therewith. The receptacle and plug communicate with the sensor. The sensor generates and transmits a signal when a threshold weight is detected and the vehicle door is ajar. The speaker receives the signal and emits an audible signal and continues to emit the signal until at least one sensor and push bottom switch are reset. A power source is coupled to the speaker.
