SENSOR SYSTEM AND METHOD FOR DETERMINING THE WEIGHT AND/OR POSITION OF A SEAT OCCUPANT
First Claim
Patent Images
1. A sensor system for determining at least one the weight and position of a seat occupant, comprising:
- at least two spaced-apart weight force sensors, which provide measured weight force signals; and
a control device, which generates a signal characterising at least one the weight and the position of a seat occupant on the basis of the measured weight force signals;
wherein the control device has a time analysis device, by means of which the time course of a measured weight force signal of at least one weight force sensor is adapted to be analysed and which provides time analysis data.

Abstract
A sensor system for determining the weight and/or position of a seat occupant, comprising at least two spaced-apart weight force sensors which provide measured weight force signals, and a control device which generates a signal characterising the weight and/or the position of a seat occupant, on the basis of the measured weight force signals, is provided, wherein the control device has a time analysis device, by means of which the time course of a measured weight force signal of at least one weight force sensor can be analysed and which provides time analysis data.

21. A seat, which is provided with a sensor system for determining at least one of the weight and position of a seat occupant, comprising:
-
at least two spaced-apart weight force sensors, which provide measured weight force signals; and a control device, which generates a signal characterising at least one of the weight and the position of a seat occupant on the basis of the measured weight force signals; wherein the control device has a time analysis device, by means of which the time course of a measured weight force signal of at least one weight force sensor can be analysed and which provides time analysis data. - View Dependent Claims (22)

23. A method for determining at least one of the weight and position of a seat occupant, in which measured weight force signals from at least two spaced-apart weight force sensors are evaluated,
wherein in addition to the evaluation of measured weight force variables, a time analysis of measured weight force signals is carried out and time analysis data are taken into account in calculating at least one of the weight and position of a seat occupant, and the measured weight force signals are checked for plausibility with the aid of the time analysis data.
