Sensor arrangement
First Claim
Patent Images
1. A sensor arrangement for recognition of seat occupancy in a motor vehicle, comprising:
- a plurality of pressure-sensitive sensor elements arranged distributed in a planar manner, each of the plurality of sensor elements having an electrical performance dependent upon a local value of a measured variable;
at least one of the of sensor elements being a non-rotationally symmetric pressure-sensitive sensor element including an active face, the active face having dimensions defining a longest line of intersection extending through the active face and a shortest line of intersection extending through the active face; and
the non-rotationally symmetric sensor element located on an installation-dependent fold line of a vehicle seat such that the longest line of intersection lies along the fold line.

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.
