Abstract

Actuating unit for automotive applications, especially motor vehicle door locks ( 1 ), comprising a drive ( 2 ) and with a linear actuator ( 3, 4 ) which can be pressurised by the drive ( 2 ), wherein the drive ( 2 ) and the linear actuator ( 3, 4 ) are arranged at an angle, and especially at a right angle, to one another.

First claim

What is claimed is:

1. An actuating unit for motor vehicle door locks, comprising: a drive having an output shaft, and a linear actuator which can be pressurised by the drive, wherein
the drive and the linear actuator are arranged at a right angle, to one another,
the drive and the linear actuator are jointly accommodated in a housing and the drive is supported via a pair of bearing points,
the pair of bearing points includes a first bearing point provided on a first end of the output shaft and a second bearing point provided on a second end of the output shaft opposite from the first end, each bearing point being a unitary component made of a same material comprising a central portion and a plurality of strip ribs made of the same material, the central portion defining an inner bearing surface for rotation of the output shaft and the plurality of strip ribs extends radially outward from the central portion and are deformed in the housing relative to the central portion during installation of the drive, the strip ribs being parallel to a central axis of the drive; and

the drive has a resilient bearing seat as a further bearing point for the drive in addition to the pair of bearing points.

2. The actuating unit in accordance with claim 1 , wherein each bearing point is formed as a bearing bushing.

3. The actuating unit in accordance with claim 1 , wherein the bearing points are formed in the housing and/or on the drive.

4. The actuating unit in accordance with claim 1 , wherein each bearing point is provided for in and/or on a separate bearing bushing.

5. The actuating unit in accordance with claim 1 , wherein the bearing points are made wholly or partially from a plastic.

6. The actuating unit in accordance with claim 1 , wherein the resilient bearing seat is made of rubber.

7. The actuating unit in accordance with claim 6 , wherein the rubber bearing seat is formed in a rubber ring which wholly or partially accommodates the drive.

8. The actuating unit in accordance with claim 1 , wherein a lid section together with an upper section form the housing which comprises at least two sections.

9. The actuating unit in accordance with claim 1 , wherein the drive is designed in a rotationally symmetrical manner and each bearing point is formed as a retaining ring or partial ring bushing.

10. The actuating unit in accordance with claim 1 , wherein the strip ribs are plastically deformed when the bearing points are installed in the housing.
