Patent Images
1. A device for detecting an occupancy of a seat, comprising:
- at least one transmitting apparatus for outputting emitted signals and disposed at a first position in the seat;
at least one receiving apparatus for receiving the emitted signals and disposed at a second position in the seat, the second position being distanced from the first position such that a person occupying the seat will be situated at least partially in a signal path between said at least one transmitting apparatus and said at least one receiving apparatus for influencing the emitted signals in dependency on seat occupancy;
at least one base station connected, for generating the emitted signals, to said at least one transmitting apparatus and, for evaluating received signals, to said at least one receiving apparatus; and
at least one sensor apparatus for determining an adjusted position of the seat in a form of seat position data, and the seat position data being taken into account when the received signals are evaluated.

Abstract
A seat occupancy detection device contains at least one transmitting apparatus and at least one receiving apparatus located at a position in a seat which position is distanced from the at least one transmitting apparatus such that a person occupying the seat will be situated at least partially in the signal path between the at least one transmitting apparatus and the at least one receiving apparatus for influencing the signals as a function of seat occupancy. In this manner, occupancy of the seat is effectively detected.
