Abstract

A roof frame arrangement of a motor vehicle has a front, a rear and two lateral roof frames, and a supporting device for a motor vehicle tailgate. The supporting device includes a tailgate hinge and at least one gas-filled compression spring. At least the lateral roof frame contains an inner shell and an outer shell connected to the latter. A hollow space is formed between the inner shell and outer shell. In order to provide a roof frame arrangement having increased stiffness, which can be produced in a simple and space-saving manner and with as few manufacturing tolerances as possible and in which a relatively great outlay on leakproofness is not required, it is proposed to form a rear end region of the lateral roof frame as a single-piece, circumferentially closed hollow profile which encloses the hollow space there and forms a receiving housing in which at least one of the hinge and the gas-filled compression spring is fitted.
