SEAT OCCUPANCY SENSOR

摘要

A sensor arrangement, as e.g. a seat occupancy sensor, comprises at least two terminals for connecting said sensor assembly to a control unit, and a first switching group of at least two switching units, said at least two switching units of said first switching group being connected together in such a way as to implement a first logical AND gate. According to the invention the sensor arrangement further comprises at least one second group of at least two switching units, wherein said at least two switching units of said second switching group are connected together in such a way as to implement a second logical AND gate and wherein said first switching group and said at least one second switching group are connected together in such a way as to implement a logical OR gate.

1. A sensor arrangement comprising:
at least two terminals for connecting said sensor assembly to a control unit, a first switching group of at least n switching units, wherein n≧3 and wherein said at least n switching units of said first switching group being connected together in such a way as to implement a first logical AND gate, and at least one second switching group of at least m switching units, wherein m≧3 and wherein said at least m switching units of said second switching group are connected together in such a way as to implement a second logical AND gate, wherein said first switching group and said at least one second switching group are connected together in such a way as to implement a logical OR gate, and wherein said sensor arrangement comprises at least one interconnection line, said interconnection line connecting a node arranged between two of said n switching units of said first switching group with at least one node arranged between two of said m switching units of said second switching group.
