• and
• a first stop preventing the display unit from moving in the initial position by abutment of a free end of the bridge on the first stop, the free end is bent in a bending plane in a direction of the guide element when moving in a direction of the first stop, the supporting element is arranged in the bending plane between the bridge and the guide element, the supporting element supports the bridge at the guide element when the bridge deforms in the direction of the guide element and prevents a deformation of the bridge away from the abutment on the first stop.
