Abstract: A curved vehicle door having a correspondingly curved windowpane and a correspondingly curved function carrier on which all of the add-on parts and door coverings are held and which can be used as protection for the occupant in the event of a lateral crash against the door. The function carrier is constructed in a sandwich-like manner from at least two shell bodies each having one of horizontal and vertical stiffening sections, the stiffening sections forming crossing points for fastening the shell bodies to each other so that the shell bodies form together a continuously closed frame of the function carrier. The outer shell body forms the curved outer side of the function carrier having at least two parallel grooves for accommodating a window lifting and lowering device which has a curvature matched to the curvature of the vehicle door.

Abstract: The invention relates to a curved vehicle door having a correspondingly curved windowpane and a correspondingly curved function carrier on which all of the add-on parts and door coverings are held and which can be used as protection for the occupant in the [lacuna] or in a militant assault, the function carrier being provided in each case along lines at least in two parallel planes with intersecting stiffening sections and advantageously being constructed in a sandwich-like manner from at least two shell bodies with longitudinal and transverse stiffening sections within a continuously closed frame, the outer shell body of which has at least two parallel grooves for accommodating a window lifting and lowering device which is matched to the curvature of the vehicle door.
