Abstract

A system of connected elements for a motor vehicle includes: a first element which has at least one depression on a surface; a second element which is arranged on the first element in such a manner that a surface of the second element and the depression of the first element form a cavity; a filling opening which forms an access to the cavity; and an adhesive which at least partially fills the cavity and thereby adhesively bonds the first element to the second element.

First claim

The invention claimed is:

1. A method for connecting elements of a motor vehicle, the method comprising the steps of:
providing a first element, the first element having a panel-like form and a depression on one surface that is formed by embossing or by impressing or by stamping;
providing a second element;
arranging the first element and the second element in such a way that a surface of the second element and the depression of the first element form a cavity;
introducing an adhesive into the cavity, the adhesive being introduced into the cavity through a filling aperture,
wherein the adhesive during introduction into the cavity has a temperature of 10 to 100° C., and/or wherein the adhesive is introduced into the cavity with a volume flow rate of 0.1 to 5 cm 3 /s.

2. The method as claimed in claim 1 , wherein the method comprises the following additional step: shaping the depression on the surface of the first element.

3. The method as claimed in claim 1 , wherein the method comprises the following additional step:
forming the filling aperture in the first element or in the second element, the filling aperture forming an access to the cavity.

4. The method as claimed in claim 1 , wherein the method comprises the following additional step:
curing the adhesive.

5. The method as claimed in claim 1 , wherein the method is carried out with elements of the system of connected elements for the motor vehicle comprising:
the first element which has at least one depression on one surface;
the second element, which is arranged on the first element in such a way that the surface of the second element and the depression of the first element form the cavity;
the filling aperture which forms an access to the cavity; and
the adhesive which at least partially fills the cavity and thereby bonds the first element to the second element.

6. The method as claimed in claim 1 , wherein the second element has a panel-like form.
