A passenger car has a self-supporting body, which has a roof opening. The roof opening is outwardly delimited in the vehicle transverse direction by lateral roof rails of the body and in the vehicle longitudinal direction by a transverse element of the body connected to the roof rails. A roof apparatus has a frame and at least one roof element that overlaps with at least part of the roof opening. The roof element is retained on the frame directly and on the body by way of the frame. The frame has a transverse frame part, on which the roof element is retained directly, the transverse frame part being connected directly to the transverse element of the body.

Passenger car

A motor vehicle has a bodyshell which forms a passenger cell. The bodyshell has two lateral side frames with in each case one front, lateral bodyshell pillar or A pillar. On a front side of the bodyshell, a front-end structure is formed, wherein the front-end structure has, on both sides, in each case one spring strut dome, one horizontally running support member arranged between the spring strut dome and the respective A pillar, and one support member running diagonally between the spring strut dome and a lower end of the A pillar. The two support members and the A pillar are assembled in monocoque construction from member profiles, wherein the three members form in each case one triangular load-bearing structure. The respective outwardly facing member profile of the A pillar, the respective outwardly facing member profile of the horizontally running support member and the respective outwardly facing member profile of the diagonally running support member are each unipartite profiles. The three profiles are connected to one another to form a triangular load-bearing structure.

Front-end structure of a motor vehicle

A motor vehicle, in which a fastening of a lower end section of a car body pillar to a side skirt is simplified in that the through-opening of the inner profile of the car body pillar for guiding the belt strap is closed at the end portion pointing of the through-opening to the inner profile of the sill by way of a fastening portion, and a left side portion and a right side portion adjoining the fastening portion. The three portions are fastened to a flange portion of the inner profile of the sill and form a covering surface from two sheet-metal portions connected to one another.
