Patent ID: 7646288

Claim:
A warning system for prompting a search of a passenger carrying vehicle for remaining passengers upon completion of a use of the vehicle, the system being selectively connectable to the vehicle electrical power system responsive to the positioning of an ignition switch of the vehicle, comprising: a) a switch actuated by a change of position of the ignition switch for alternatively connecting elements of the warning system to the vehicle electrical power system; b) a voice module in said warning system for providing a repeating audible voice message upon positioning the ignition switch to its “off” position following the ignition switch having been positioned to its “on” position; c) a timer in said warning system for timing a predetermined period of time following positioning the ignition switch to its “off” position following the ignition switch having been positioned to its “on” position; d) alarm for providing an alarm initiated by said timer following a predetermined time signaled by said timer following positioning the ignition switch to its “off” position following the ignition switch having been positioned to its “on” position; e) switch for disabling said voice module and said alarm, said switch being physically mounted in the vehicle at a distance from the ignition switch greater than the physical reach of an operator of the vehicle; whereby upon positioning the ignition switch to its “off” position following the ignition switch having been positioned to its “on” position, said voice module prompts a search for remaining passengers in the vehicle and a later timed alarm is actuated if not disabled by activation of said switch subsequent to positioning the ignition switch to its “off” position following the ignition switch having been positioned to its “on” position; and f) a standby switch positioned electrically in series with the ignition switch and said warning system, said standby switch operably disabling said voice module and alarm on subsequent positioning of the ignition switch to its “on” position following the ignition switch having been positioned to its “off” position whereby said standby switch disables said warning system only after a full cycle of operation of said warning system including activation of said switch or activation of said voice module and alarm.
