Abstract

A door handle assembly for a vehicle includes a handle portion and an antenna positioned within the handle portion. The handle portion is movable or actuatable to open the door of the vehicle. The antenna receives a signal from a remote signaling device and communicates a signal to an accessory or system of the vehicle, such as a door locking/unlocking system of the vehicle, a lighting system of the vehicle, an ignition system of the vehicle, and/or the like. The antenna may function to receive the signal and automatically communicate a signal to the accessory or system of the vehicle in response to a remote signaling device approaching the door handle assembly. The antenna is preferably positioned within a cavity of the door handle portion and, more preferably, the handle portion is molded at least substantially around the antenna.

Claims

1. A door handle assembly for a door of a vehicle, the vehicle including a door locking system, said door handle assembly comprising:

a base portion adapted to mount to the door of the vehicle;

a handle portion, said handle portion being movably mounted to said base portion, said handle portion comprising an outer portion molded from a first polymeric material;

an antenna; and

an inner core portion molded from a second polymeric material, said inner core portion disposed at least partially around said antenna to at least partially encase said antenna within said inner core portion, said outer portion of said handle portion disposed at least partially around and contacting said inner core portion to at least partially encase said inner core portion within said outer portion, said antenna being adapted to receive a signal from a remote signaling device and communicating the signal to the door locking system of the vehicle.

2. The door handle assembly of claim 1, wherein said antenna includes at least one wire extending therefrom, said inner core portion being molded at least partially around said antenna and said at least one wire such that an end of said at least one wire extends from said molded inner core portion.

3. The door handle assembly of claim 1, wherein said first polymeric material of said outer portion and said second polymeric material or said inner core portion comprise different polymeric materials.

4. The door handle assembly of claim 3, wherein said first polymeric material of said outer portion and said second polymeric material of said inner core portion comprise compatible polymeric materials.

5. The door handle assembly of claim 1, wherein said first polymeric material of said outer portion and said second polymeric material of said inner core portion comprise common polymeric materials.

6. The door handle assembly of claim 1, wherein said second polymeric material of said inner core portion and said first polymeric material of said outer portion of said handle portion comprise one of a mineral filled nylon material and a glass filled nylon material.

7. The door handle assembly of claim 1, wherein said handle portion is integrally molded at least partially around said inner core portion and said antenna.

8. The door handle assembly of claim 1, wherein said antenna communicates the signal to the door locking system via a wire connection between the locking system and said antenna.

9. The door handle assembly of claim 1, wherein said antenna communicates the signal to the door locking system via a wireless signal.

10. The door handle assembly of claim 1, wherein said antenna communicates the signal to the door locking system via at least one of a vehicle bus or multiplex system.

11. The door handle assembly of claim 1, wherein said antenna communicates the signal to the door locking system in response to a signal from a remote signaling device.

12. The door handle assembly of claim 11, wherein said antenna communicates the signal to the door locking system automatically in response to the remote signaling device approaching said door handle assembly.

13. The door handle assembly of claim 1, wherein said antenna communicates the signal to at least one other vehicle accessory.

14. The door handle assembly of claim 13, wherein said at least one other vehicle accessory comprises at least one of a vehicle lighting system, an interior light, a security light and a vehicle ignition.

15. The door handle assembly of claim 1, wherein said handle portion comprises an elongated strap handle portion pivotable about a generally vertical axis at said base portion.

16. A door handle assembly rot a door of a vehicle, the vehicle including a door locking system, said door handle assembly comprising:

a base portion adapted to mount to the door of the vehicle;

a handle portion, said handle portion being movably mounted to said base portion, said handle portion comprising a molded shell portion;

an antenna; and

an inner core portion molded at least partially around said antenna, said shell portion being molded at least partially around and contacting said inner core portion, said antenna receiving a signal from a remote signaling device and communicating the signal to the door locking system of the vehicle.

17. The door handle assembly of claim 16, wherein said antenna includes at least one wire extending therefrom, said inner core portion being molded at least partially around said antenna and said at least one wire such that an end or said at least one wire extends from said molded inner core portion.

18. The door handle assembly of claim 16, wherein said inner core portion and said shell portion comprise one of a mineral filled nylon material and a glass filled nylon material.

19. The door handle assembly of claim 16, wherein said shell portion of said handle portion is integrally molded at least partially around said inner core portion.

20. The door handle assembly of claim 16, wherein said antenna is substantially encased within said inner core portion, said shell portion of said handle portion defining an outer layer molded at least partially around and contacting said inner core portion.

21. The door handle assembly of claim 20, wherein said antenna includes a wire extending from said core portion and said outer layer of said handle portion.

22. The door handle assembly of claim 16, wherein said antenna communicates the signal to the door locking system via at least one of a wire connection and a wireless signal.

23. The door handle assembly of claim 16, wherein said antenna communicates the signal to the door locking system via a wire connection between the locking system and said antenna.

24. The door handle assembly of claim 16, wherein said antenna communicates the signal to the door locking system via a wireless signal.

25. The door handle assembly of claim 16, wherein said antenna communicates the signal to the door locking system via at least one of a vehicle bus or multiplex system.

26. The door handle assembly of claim 16, wherein said antenna communicates the signal to the door locking system automatically in response to a remote signaling device approaching said door handle assembly.

27. The door handle assembly of claim 16, wherein said antenna communicates the signal to at least one other vehicle accessory.

28. The door handle assembly of claim 27, wherein said at least one other vehicle accessory comprises at least one of a vehicle lighting system, an interior light, a security light and a vehicle ignition.

29. The door handle assembly of claim 16, wherein said handle portion comprises an elongated strap handle portion pivotable about a generally vertical axis at said base portion.
