Abstract: A seat arrangement for a motor vehicle, having a vehicle seat with a backrest and a seat part which is arranged in a seating position above a storage region and at least partially covers on the upper face an access opening to the storage region, which is configured in a seat substructure, and which is pivotable about a seat pivot axis into a folded-up position in order to uncover the access opening. In order to permit a flexible and efficient use of the storage space in the region of the vehicle seat, the seat arrangement has at least one storage container with a wall which is configured around the periphery to the side and on the lower face, said storage container being able to be inserted into the storage region through the access opening and being able to be received therein so as to prevent displacement in the horizontal direction.

Abstract: A method determines state information relating to a belt grinder. The belt grinder has at least one abrasive belt for grinding a workpiece. The method includes providing measurement data relating to the belt grinder, and determining the state information from the measurement data using a machine learning system. The machine learning system is configured to determine the state information based on the provided measurement data.

Abstract: A vehicle seat for a motor vehicle, comprising a seat part with a seat cushion which provides a seat surface and which comprises a front seat portion and a rear seat portion extending diametrically thereto, and a backrest with a lower backrest portion and an upper backrest portion extending diametrically thereto. The lower backrest portion of the backrest is arranged adjacent to the rear seat portion of the seat cushion.
