Abstract

A vehicle door assembly comprising includes a vehicle door panel, a vehicle door handle operably connected to the door panel so as to enable operation of a door latch by the door handle, and at least one sanitizer dispensing mechanism having at least a first nozzle coupled to the vehicle door panel and structured to discharge a sanitizing material onto an exterior surface of the door handle.

First claim

What is claimed is:

1 . A vehicle door assembly comprising:
a vehicle door panel; a vehicle door handle operably connected to the door panel so as to enable operation of a door latch by the door handle; and at least one sanitizer dispensing mechanism having at least a first nozzle coupled to the vehicle door panel and structured to discharge a sanitizing material onto an exterior surface of the door handle.

2 . The vehicle door assembly of claim 1 wherein the at least a first nozzle is structured to reside at a level vertically higher than the door handle when the vehicle door assembly is mounted on a vehicle.

3 . The vehicle door assembly of claim 2 wherein the at least a first nozzle is an atomizer structured to dispense a fine mist of sanitizing material.

4 . The vehicle door assembly of claim 2 wherein the at least a first nozzle is structured to dispense the sanitizing material in an arcuate distribution from the at least a first nozzle along a horizontal plane located above the door handle when the vehicle door assembly is mounted on the vehicle.

5 . The vehicle door assembly of claim 2 wherein the at least a first nozzle is positioned along a vertical plane bisecting a length of the door handle.

6 . The vehicle door assembly of claim 2 wherein the vehicle door panel includes a recess structured to receive at least a portion of the door handle therein and wherein the at least a first nozzle is mounted within the recess.

7 . The vehicle door assembly of claim 1 wherein the at least a first nozzle is structured to dispense the sanitizing material onto an uppermost exterior surface of the door handle.

8 . The vehicle door assembly of claim 1 wherein the at least a first nozzle is structured to dispense the sanitizing material onto an outermost exterior surface of the door handle.

9 . The vehicle door assembly of claim 1 wherein the at least a first nozzle is structured to dispense the sanitizing material onto an innermost exterior surface of the door handle.

10 . The vehicle door assembly of claim 1 wherein the vehicle door panel includes an opening formed therein, wherein the door assembly includes a door handle module structured to be secured in the opening, the door handle module including a recess structured to receive the at least a portion of the door handle therein.

11 . The vehicle door assembly of claim 1 further comprising a second nozzle coupled to the vehicle door panel and structured to discharge a sanitizing material onto a lowermost exterior surface of the door handle.

12 . The vehicle door assembly of claim 11 wherein the second nozzle is structured to dispense the sanitizing material onto an innermost exterior surface of the door handle.

13 . The vehicle door assembly of claim 1 wherein the vehicle door assembly is mounted on a vehicle, the vehicle including one or more processors and a memory communicably coupled to the one or more processors and storing a vehicle door handle sanitizing system control module including computer-readable instructions that when executed by the one or more processors cause the one or more processors to control operation of the at least one dispensing mechanism to discharge the sanitizing material onto an exterior surface of the door handle responsive to information received from at least one sensor mounted on the vehicle and in operative communication with the door handle sanitizing system control module.

14 . The vehicle door assembly of claim 13 wherein the vehicle includes at least one door latch sensor configured to detect when the vehicle door is latched and wherein the control module includes computer-readable instructions that when executed by the one or more processors cause the one or more processors to:
determine if a predetermined time period has passed since the vehicle door was latched; and
responsive to passage of the predetermined time period after the vehicle door was latched, control operation of the at least one dispensing mechanism to discharge the sanitizing material onto the exterior surface of the door handle.

15 . The vehicle door assembly of claim 13 wherein the vehicle includes at least one door lock sensor configured to detect when the vehicle door is locked and wherein the control module includes computer-readable instructions that when executed by the one or more processors cause the one or more processors to:
determine if a predetermined time period has passed since the vehicle door was locked; and
responsive to passage of the predetermined time period after the vehicle door was locked, control operation of the at least one dispensing mechanism to discharge the sanitizing material onto the exterior surface of the door handle.
