Vehicle exit signaling system

Claim 2

A vehicle exit signaling system comprising: a. manual actuator means; b. audio signal means responsive to momentary actuation of said manual actuator means for producing audio signals in the vehicle indicative of a passenger''s desire to disembark; c. visual signal means enabled by operation of said manual actuator means for continuously providing visual signals; and d. circuit means responsive to said momentary actuation of said manual actuator means for disenabling said audio signal means subsequent to said momentary actuation of the manual actuator means.

Claim 3

The system set forth in claim 1 wherein said means for disenabling said audio signal means maintains operation of said visual signal means.

Claim 4

The system set forth in claim 2 together with reset means for selectively disabling said circuit means to enable said audio signal means for subsequent operation by of said manual actuator means.

Claim 5

The system set forth in claim 3 wherein said reset means for selectively disabling said circuit means is responsive to operation of a vehicle exit door.

Claim 6

The combination of claim 1 wherein said circuit means includes timing means for maintaining the audio signal means in operation for a predetermined interval of time following said momentary actuation of the manual actuator means.

Claim 7

In combination with a source of electrical energy and a signalling system having audible and visual alerting devices simultaneously energized by said source upon momentary actuation of a signalling switch, means for controlling operation of said alerting devices, comprising self-latching relay means connected to said source by the signalling switch for energization simultaneously with the audible alerting device in response to said momentary actuation of the switch, timing means responsive to energization of the relay means for initiating a timing cycle of predetermined duration, means responsive to termination of said timing cycle for disabling the audible alerting device, means connecting the visual alerting device to the relay means in by-pass relation to the timing means for continuous operation while the relay means is energized, and reset means connected to the relay means for deenergization thereof to disable the visual alerting means and recondition the audible device for operation.

Claim 8

In combination with a source of electrical energy and a signalling system having audible and visual alerting devices simultaneously energized by said source upon momentary actuation of a signalling switch, means for controlling operation of said alerting devices, comprising self-latching relay means connected to said source by the signalling switch for energization simultaneously with the audible alerting device in response to said momentary actuation of the switch, timing means responsive to energization of the relay means for initiating a timing cycle of predetermined duration, means responsive to termination of said timing cycle for disabling the audible alerting device, means connecting the visual alerting device to the relay means in by-pass relation to the timing means for continuous operation while the relay means is energized, and reset means connected to the relay means for deenergization thereof to disable the visual alerting means and recondition the audible device for operation.

Claim 9

The combination of claim 6 wherein said relay means includes a relay coil connected to the source in series with the signalling switch and the reset means, a relay holding switch connecting the source to the relay coil in by-pass relation to the signalling switch, a relay control switch connecting the visual alerting device to the source in series with said relay holding switch, and a timer control switch connected in series with the timing means.

Claim 10

The combination of claim 7 wherein said timing means includes a time delay relay connected in series with the signalling switch and the timer control switch to said source and having normally closed contacts connected in series with the audible alerting device to the source.
