ABSTRACT:
A seat belt alarm system activates an alarm when a child is buckled in a car seat and when the car key is removed from the ignition. The seat belt alarm system includes a belt buckle having a belt-buckled sensor and a transmitter that transmits a belt-buckled signal when the belt is buckled. A remote key module includes a key-removed sensor that senses when the key is not in a keyhole. The key module further includes a receiver and an alarm device that is activated when the key is not in the keyhole and the belt-buckled signal is received from the transmitter. In another variation, a controller is provided. The controller may be coupled to various components including the belt-buckled sensor, a key-removed sensor, a transmitter and additional devices such as a horn, air conditioning, etc. The controller instructs the transmitter to send an activate-alarm signal to a receiver in the key module when a belt-buckled signal and a key-removed signal are input to the controller. The alarm device may provide a sound, vibration, light, or another indicator. Another variation includes a removable baby seat with a seat belt alarm system. Still another variation includes an automobile having a seat belt alarm system.
