Seat arrangement for a motor vehicle, having: a seat which has a seat structure for providing structural dimensions and structural strength for accommodating at least one person sitting thereon, and a seat padding which is applied at least to a seat surface portion of the seat structure such that said seat padding forms a seat surface for the at least one person, a backrest which has a backrest structure for providing structural dimensions and structural strength for the rear-side support of the at least one person, and a backrest padding which is applied at least to a contact surface portion of the backrest structure such that said backrest padding forms a contact surface for the at least one person, and a side airbag device which is integrated in the backrest adjacent to a lateral backrest boundary, wherein the side airbag device is integrated in the backrest in such a manner that, in a width direction of the seat arrangement in relation to a side member of the backrest structure, said side member corresponding to the lateral backrest boundary, said side airbag device is arranged offset with respect to a centre of the backrest and is overlapped, as seen in the width direction, by the side member on the side of the lateral backrest boundary, characterized in that the seat padding has, as an edge region, a bead exceeding the seat surface in terms of height, and in that the seat arrangement has a sensor device, with a first pressure sensor which engages in the bead in such a manner that said pressure sensor can identify a pressure load acting obliquely from above on the bead from the side of the seat surface and, on identifying such a pressure load, can generate a first identification signal, and with a second pressure sensor which engages in the bead in such a manner that said pressure sensor identify a pressure load acting vertically from above on the bead and, on identifying such a pressure load, generates a second identification signal, wherein, by means of the first identification signal, a warning signal is generated by the electronic control device, to which the sensor device 30 is connected, and is perceptible to people in the passenger compartment by means of a visual output device and/or a sound-generating output device, and in that, when the second identification signal is present, the latter is identified as the overlapping signal by the electronic control device, and a deactivation signal is output to the side airbag device by the electronic control device on the basis of an overlapping signal if a person located on the seat arrangement overlaps a seam-shaped airbag outlet region of the side airbag device that is formed on the backrest adjacent to the lateral backrest boundary. a seat which has a seat structure for
