An organic light emitting diode display that is flexible is disclosed. The controller includes a sensor for sensing a temperature of the respective segments, said temperature indicative of an extent of the overlapping print regions. A side of the angle adjusting device is connected to the backrest frame, and another side of the angle adjusting device is connected to the seat frame. The pretensioning device is configured to cinch and lock the shoulder stabilizing zone around a shoulder region of the occupant, thereby preventing forward rotation of the shoulder region, in response to a side impact collision. After a laboratory performs testing specified in an order, the laboratory may enter the testing results, which are routed to recipients indicated for the results. The contact field is equipped with several metallic contacts for a connection with a twisted-pair socket, with each metallic contact having a feed line section for a connection with a circuit board.
