Abstract
A rollover device for a passenger compartment of a motor vehicle includes a plurality of struts made of fiber-reinforced plastic, and a plurality of fastening feet made of metallic material for connecting the rollover device to a vehicle body. At least one fastening foot made of metallic material is connected to a respective strut made of fiber-reinforced plastic via a material-locking connection on the one hand and via a form-locking connection on the other hand.
Claims13
A rollover device for a passenger compartment of a motor vehicle, said rollover device comprising:
- a plurality of struts composed of fiber-reinforced plastic,
- a plurality of fastening feet composed of metallic material for connecting the rollover device to a vehicle body,
- wherein at least one fastening foot of said plurality of fastening feet that is composed of metallic material is connected to a respective strut of the plurality of struts that is composed of fiber-reinforced plastic via a material-locking connection as well as a form-locking connection,
- wherein the material-locking connection is an adhesive connection, and
- wherein the form-locking connection is a bolt, screw or rivet connection.
A rollover device for a passenger compartment of a motor vehicle, said rollover device comprising:
- a plurality of struts composed of fiber-reinforced plastic,
- a plurality of fastening feet composed of metallic material for connecting the rollover device to a vehicle body,
- wherein at least one fastening foot of said plurality of fastening feet that is composed of metallic material is connected to a respective strut of the plurality of struts that is composed of fiber-reinforced plastic via a material-locking connection as well as a form-locking connection,
- wherein the at least one fastening foot projects partly into a first end of the respective strut, which respective strut is at least partly hollow and forms an overlap region with the at least one fastening foot, wherein the material-locking connection is configured along the overlap region, and at least one form-locking fastening means extends through the overlap region to create the form-locking connection,
- wherein openings are disposed in the first end of the respective strut and in the at least one fastening foot in the overlap region through which openings the at least one form-locking fastening means extends, wherein the openings are implemented as an entry opening and an exit opening in the at least one fastening foot as well as an entry opening and an exit opening in the respective strut, wherein the entry and exit openings of the at least one fastening foot and the respective strut are respectively configured opposite to one another on the first end of the respective strut and in the at least one fastening foot, wherein longitudinal axes of the entry and exit openings of the at least one fastening foot and the respective strut are disposed on a straight line, wherein the entry openings of the at least one fastening foot and the respective strut have diameters that are larger than diameters of the exit openings of the at least one fastening foot and the respective strut.
A method for producing a rollover device including struts made of fiber-reinforced plastic and fastening feet made of metallic material, said method comprising the following steps:
- connecting at least one fastening foot made of metallic material to a respective strut made of fiber-reinforced plastic via both a material-locking connection and a form-locking connection,
- wherein the material-locking connection is an adhesive connection, and
- wherein the form-locking connection is a bolt, screw or rivet connection.
