Abstract

An exterior door handle system ( 2 ) in a motor vehicle has a bearing bracket ( 11 ) on an interior side ( 10 ) of an exterior door panel ( 1 ) and a door handle ( 12 ) on an exterior side ( 9 ) of the exterior door panel ( 1 ). The door handle ( 12 ) is mounted from the exterior and penetrates the exterior door panel ( 1 ) for mounting in the bearing bracket ( 11 ). A unit ( 19 ) formed from a lock barrel ( 20 ) and a housing ( 21 ) for the lock barrel ( 20 ) is mounted in the bearing bracket ( 11 ) from the interior and is covered on the exterior side ( 9 ) of the exterior door panel ( 1 ) by a protective cap ( 24 ). A locking clip ( 30 ) is mounted in the bearing bracket ( 11 ) arranged on the interior side ( 10 ) and locks both the unit ( 19 ) and the protective cap ( 24 ) counter to their respective mounting direction.

First claim

What is claimed is:

1. An exterior door handle system to be mounted on an exterior door panel of a motor vehicle, the exterior door handle system comprising:
a bearing bracket arranged on an interior side of the exterior door panel, the bearing bracket having an outer surface held substantially in contact with the exterior door panel, an inner surface, a side surface extending between the outer and inner surfaces, an opening formed between the outer and inner surfaces corresponding to an opening formed in the exterior door panel, and a slot-shaped receptacle formed in the side surface in communication with the opening in bearing bracket;
a unit formed from a lock barrel and a housing for the lock barrel, the unit being inserted along an insertion direction into the opening of the bearing bracket from the inner surface of the bearing bracket so that a leading edge of the unit penetrates the opening in the exterior door panel, and an array of coplanar grooves formed in an outer surface of the unit and defining a plane substantially normal to the insertion direction bracket of the unit into the bearing bracket;
a protective cap mounted from an exterior side of the exterior door panel and covering the leading edge of the unit, the protective cap having first and second spaced apart projections projecting through the opening in the exterior door panel, the first projection having two coplanar first grooves facing in opposite directions and the second projection having at least one second groove coplanar with the first grooves, the first and second grooves of the protective cap being coplanar with the coplanar grooves of the unit;
a door handle arranged on the exterior side of the exterior door panel and being mounted to the bearing bracket;
a substantially U-shaped locking clip having a first plate and a second plate that are perpendicular to one another, at least the first plate being configured to be inserted into the receptacle, the first plate of the locking clip having a crosspiece and first and second limbs projecting from the crosspiece and spaced from each other, the crosspiece and the limbs being substantially coplanar, first and second locking piece projections formed respectively on the first and second limbs to project towards each other, and the second plate having a hole penetrating therethrough; and
a screw passing through the hole in the second plate of the locking clip, through the bearing bracket and engaged threadedly in the housing of the unit, wherein
the crosspiece and the limbs of the locking clip engages plural areas of the at array of grooves of the unit, the crosspiece further engages the at least second groove of the protective cap, and the first and second limbs of the locking clip respectively engage the two oppositely facing first grooves of the protective cap.

2. The exterior door handle system of claim 1 , wherein the locking clip is formed from a unitary plate.

3. The exterior door handle system of claim 1 , wherein the screw connecting the locking clip and housing, is aligned substantially perpendicular to the insertion direction of the unit.

4. The exterior door handle system of claim 1 , wherein the screw mounted in the hole of the locking clip is fixed axially by a securing ring that is connected to the screw.

5. The exterior door handle system of claim 4 , wherein the locking clip is composed of steel sheet.
