Abstract: The recognition of seat occupancy of a seat is achieved by recording at least one measured signal by way of a seat occupancy sensor. The measured signal is allocated a weight signal by way of an allocation rule, which is representative of a weight with which the seat is occupied. The allocation rule is altered when the weight signal over the course of time is first greater than a given upper threshold and when further, during a given first duration the weight signal lies in a first weight range at a weight zero value. The allocation rule is altered such that the then current measured signal is allocated the weight signal reduced by a given percentage from the weight signal. The allocation rule is further altered when the weight signal lies around the weight zero value in a given second weight range during a given second duration, which is much longer than the first duration.

Abstract: At least two weight sensors are disposed below the seat such that measured values of the at least two weight sensors are representative of a force which is transmitted from the seat to its mount. At least two measured values are detected at a chronological interval from each other within a predetermined period of time by the weight sensors. A weight sensor is arranged in a first region of the seat and a weight sensor is arranged in a second region of the seat. A gradient is determined from the respective at least two measured values for the particular weight sensor. The jamming of the seat is recognized in dependence on the presence of different gradient signs that are assigned to the weight sensor disposed in the first region of the seat and to the weight sensor disposed in the second region of the seat.
