## 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.

## Claims

### Claim 1

An actuating unit for automotive applications, namely motor vehicle door locks (1), comprising: a drive (2), and 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 namely at a right angle, to one another.

### Claim 2 (depends on 1)

The actuating unit in accordance with claim 1, wherein the drive (2) and the linear actuator (3, 4) are jointly accommodated in a housing (8a, 8b).

### Claim 3 (depends on 2)

The actuating unit in accordance with claim 2, wherein the drive (2) is connected to the housing (8b) by at least one bearing point (7, 7′).

### Claim 4 (depends on 3)

The actuating unit in accordance with claim 3, wherein the bearing point (7, 7′) is formed as a die seat (7, 7′).

### Claim 5 (depends on 3)

The actuating unit in accordance with claim 3, wherein the bearing point (7, 7′) is formed in several sections.

### Claim 6 (depends on 3)

The actuating unit in accordance with claim 3, wherein the bearing point (7, 7′) is equipped with bars (12) which are deformed in the housing (8a, 8b) during installation of the drive (2).

### Claim 7 (depends on 6)

The actuating unit in accordance with claim 6, wherein the bars (12) are formed as flexible ribs (12).

### Claim 8 (depends on 3)

The actuating unit in accordance with claim 3, wherein the bearing point (7, 7′) is formed in the housing (8a, 8b) and/or on the drive.

### Claim 9 (depends on 3)

The actuating unit in accordance with claim 3, wherein the bearing point (7, 7′) is provided for in and/or on a separate bearing bushing (7).

### Claim 10 (depends on 3)
