Abstract

A security configuration in or for a motor vehicle, which includes a bodywork part, such as a door, and a window pane arranged in the bodywork part. The security configuration includes a touch-sensitive keypad integrated in or mounted to the window pane. The keypad has a plurality of touch sensors, each of which takes the form of resonant oscillating circuits and via which an actuation of a respective touch sensor can be picked up. An electronic evaluation system is configured for the purpose of detecting an actuation of the keypad and attributing said actuation to a respectively actuated touch sensor. There is also provided a motor vehicle which includes such a security configuration.
