Abstract
The invention relates to a frame, comprising, on each of its two sides relative to a vertical longitudinal center plane of the roof, a respective longitudinal beam made of sheet metal and at least one transverse beam made of sheet metal and connecting the two longitudinal beams to each other. The longitudinal beams and the at least one transverse beam are connected to each other via joint lines made of polyurethane foam. Moreover, a method for producing the frame is proposed.
Claims21
A vehicle roof comprising a frame, which at least partially surrounds a roof opening, which can be closed or at least partially released as desired by means of a lid element, and/or serves for supporting and fixing a rigid roof panel forming a hard top section, comprising, on each of its two sides relative to a vertical longitudinal center plane of the roof, a respective longitudinal beam made of sheet metal and at least one transverse beam made of sheet metal and connecting the two longitudinal beams to each other, wherein the longitudinal beams and the at least one transverse beam are connected to each other via joint lines made of polyurethane foam.
A vehicle roof comprising a frame, which at least partially surrounds a roof opening, which can be closed or at least partially released as desired by means of a lid element, and/or serves for supporting and fixing a rigid roof panel forming a hard top section, comprising, on each of its two sides relative to a vertical longitudinal center plane of the roof, a respective longitudinal beam made of sheet metal and at least one transverse beam made of sheet metal and connecting the two longitudinal beams to each other, wherein the vehicle roof comprises at least one functional section, which is made of a polyurethane foam and is connected to at least one of the longitudinal beams and/or the transverse beam.
A vehicle roof comprising a frame, which at least partially surrounds a roof opening, which can be closed or at least partially released as desired by means of a lid element, and/or serves for supporting and fixing a rigid roof panel forming a hard top section, comprising, on each of its two sides relative to a vertical longitudinal center plane of the roof, a respective longitudinal beam made of sheet metal and at least one transverse beam made of sheet metal and connecting the two longitudinal beams to each other, wherein the vehicle roof comprises a visible surface, which is made of a polyurethane foam connected to at least one of the longitudinal beams and/or the transverse beam.
A method for producing a frame of a vehicle roof, which at least partially surrounds a roof opening, which can be closed or at least partially released as desired by means of a lid element, and/or serves for supporting and fixing a rigid roof panel forming a hard top section and which comprises, on each of its two sides relative to a vertical longitudinal center plane of the roof, a respective longitudinal beam made of sheet metal and at least one transverse beam made of sheet metal and connecting the two longitudinal beams to each other, wherein the longitudinal beams and the transverse beam are connected to each other via a polyurethane foam according to a foam molding process and under formation of joint lines.
