Abstract

A handle unit for a vehicle door lock system has a lever door handle mounted on a pivot in a housing. The lever can be locked in the position which corresponds to a "door locked" condition. A release button allows the lever to be locked or released so that the lever can be operated. The lever is locked by a detent which captures the lever and can be released by pushing the detent away from the lever.

Claims

1. A door handle unit for a vehicle door lock system, the unit comprising a housing adapted to be flush-mounted in a door trim panel, a handle assembly pivotally mounted in the housing and means for connecting one end of a door lock operating cable to the handle assembly, the handle assembly comprising a handle and a release member both mounted on a common pivot axis in the housing and a detent member arranged to capture the handle when a locked condition of the handle is set and to prevent the handle being moved to an unlocked condition, and means for operating the release member to move the detent and to release the handle, and wherein the handle is spring-loaded for movement on the pivot axis so that, when the detent is moved, the handle is spring-biased to its unlocked position.

2. A door handle unit as defined in claim 1, wherein the operating cable is connected directly to the handle, and the handle is movable between locked and unlocked conditions, and further movable between unlocked and unlatched positions.

3. A door handle unit as defined in claim 1 or claim 2, wherein the release member is mounted between two side portions of the handle.

4. A door handle unit as defined in claim 1, wherein the release member is a cam mounted on the same pivot in the housing as the door handle itself.

5. A door handle unit as defined in claim 1, wherein there is a lost motion connection between the release member and the handle.

6. A door handle unit as defined in claim 1, wherein the release member includes a button which can be pressed to operate the member.

7. A door handle unit as defined in claim 1, wherein the detent is spring-loaded to a position engaging a portion of the handle.

8. A door handle unit as defined in claim 7, wherein the spring-loaded detent is a pawl.

9. A door handle unit as defined in claim 7, wherein the spring-loaded detent is a stiff wire loop.

10. A door handle unit as defined in claim 1, wherein the release member is located in a slot-like recess in the handle itself.
