Abstract

A frame structure for a motor vehicle body includes at least two profile components and a connecting node, which connects the profile components with each other. At least one of the profile components has at least one console which is made of fiber reinforced plastic and on which other components can be fastened or supported.

First claim

What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims and includes equivalents of the elements recited therein:

1. A frame structure for a motor vehicle body, said frame structure comprising:
at least two profile components; and
a connecting node which connects the at least two profile components with each other, and at least one of the at least two profile components has at least one console made of fiber reinforced thermoset plastic, said at least one console having a metallic insert configured as a force application point anchored in the fiber reinforced thermoset plastic of the console, said at least one console being adapted for fastening or supporting other components thereon.

2. The frame structure of claim 1 , wherein the console has at least one of a connecting section and an integrated load introduction element.

3. The frame structure of claim 1 , wherein the console is made of a plastic that is reinforced with short fibers.

4. The frame structure of claim 1 , wherein the console is formed about the profile component in the manner of a sleeve.

5. The frame structure of claim 1 , wherein the console is arranged on a free end of the one of the at least two profile components and forms an end piece of the one of the at least two profile components.

6. The frame structure of claim 1 , wherein the at least two profile components are made of a fiber reinforced plastic composite material.

7. A method for producing a console on a profile component for a frame structure, said method comprising the steps of:
positioning the profile component in a pressing tool that produces the console;
performing a pressing procedure in the presence of a fiber containing thermoset plastic mass in the pressing tool for generating the console;
opening the pressing tool and removing the profile component with the console formed thereon; and
anchoring a metallic insert configured as a force application point in the fiber reinforced thermoset plastic of the console.

8. The method of claim 7 , wherein the fiber-containing plastic mass is SMC or BMC.

9. The method of claim 7 , wherein the profile component is a hollow profile component and the console is molded onto a free end of the hollow profile component, the method further comprising closing an open profile end of the hollow profile component with a closing element which during the pressing procedure prevents entering of the fiber-containing plastic mass into the hollow profile component.

10. A motor vehicle, comprising:
a frame structure, said frame structure comprising at least two profile components and a connecting node which connects the at least two profile components with each other, and at feast one of the at least two profile components has at least one console made of fiber reinforced thermoset plastic, said at least one console having a metallic insert configured as a force application point anchored in the fiber reinforced thermoset plastic of the console, said at least one console being adapted for fastening or supporting other components thereon.

11. The motor vehicle of claim 10 , wherein the frame structure is produced with the following method steps:
positioning the profile component in a pressing tool;
performing a pressing procedure in the presence of a fiber containing plastic mass in the pressing tool for generating the console; and
opening the pressing tool and removing the profile component with the console formed thereon.
