1. A device for actuating electronic equipment in a motor vehicle, comprising:
- a sensor element for generating electronic signals as a function of positions of persons and/or objects in a passenger compartment of the motor vehicle; and
an evaluation unit for evaluating the electronic signals, the evaluating being responsive to the status of the ignition of the motor vehicle to perform plural functions of airbag control and antitheft control with said sensor element;
wherein the sensor element comprises a picture-taking sensor unit, and the evaluation unit is operative to recognize pictures of the picture-taking sensor unit;
wherein the evaluation unit is operative to sense sizes and/or weights of the persons.

Abstract
A device for actuating electronic equipment in a motor vehicle has a picture-taking sensor unit (21) for monitoring the passenger compartment (1) of the motor vehicle and a evaluation unit (22) for recognizing pictures of the picture-taking sensor unit (21). If the piece of electronic equipment is an airbag (12-15) arranged in front of a vehicle seat (2-4), the triggering of the airbag (12-15) in the event of a crash can be prevented if there is no person (5-7) or no object (8) located on the vehicle seat (2-4).
