Abstract: The invention relates to a roller shutter system for a motor vehicle body, in particular for a fire brigade vehicle, with a roller shutter armor (26) formed by slats (25) connected in an articulated manner to one another. Guide arrangements (27) extend on both sides of the roller shutter armor (26) between a floor virtually as far as a ceiling of a machine body. The roller shutter armor (26) is provided with an opening and locking device on an end slat facing the floor. The guide arrangement (27) is formed by a first guide profile (34) which is connected to the machine body and forms at least one guide track (51). A further guide profile (52) is detachably connected to the first guide profile (34). An end profile (65) which, by means of at least one elastic sealing lip (68), covers an end region of the slats (25), is arranged on the further guide profile (52).
