Abstract: The present invention relates to a contactless detector unit for a load suspension device, which may be used, for example, for recognizing passengers in a motor vehicle, and to a corresponding load suspension device. In order to provide a detector unit for a load suspension device that, on the one hand, may be optimally calibrated and thus provides improved precision and, on the other hand, may be produced particularly cost-effectively, the overall structure being particularly stable and robust, the detector unit comprises a sensor for producing a sensor signal in response to a geometrical position of an indicator with respect to the sensor. The sensor is assembled in an assembly unit, and the position of the indicator may be changed by an actuating unit in response to a load. According to the invention, the indicator is arranged on the assembly unit, and the assembly unit comprises a flexible region, which may be moved for changing the geometrical position of the indicator with respect to the sensor.
