ABSTRACT:
The invention relates to planar sensor arrangements, in particular seat mat sensors, for recognition of seat occupancy in a motor vehicle, comprising several pressure sensitive sensor elements, arranged in a planar distribution, the electrical properties of which are dependent on the local value of a measured parameter and having at least one non-rotationally symmetrical sensor element on an insulation-dependent fold line of the sensor arrangement, with a longest sectional line through the active surface of the sensor element arranged along the fold line.
