BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The invention is described by way of example hereinafter with reference to the accompanying drawings with reference to advantageous embodiments. In the drawings:

[0023] FIG. 1 shows a sectional view of a fastening system according to the invention in the separated state;

[0024] FIG. 2 shows a sectional view of a fastening system according to the invention in the connected state; and

[0025] FIG. 3 shows a detail of FIG. 1 in an enlarged view.

DETAILED DESCRIPTION

[0026] A fastening system shown in FIG. 1 comprises a first component 14 and a second component 15. The first component 14 comprises a plurality of fastening projections 16. A fastening receiver 17 is enclosed between two adjacent fastening projections 16 in each case. Shown in FIG. 1 are seven fastening projections 16 arranged adjacent to one another with six fastening receivers 17 arranged therebetween. The fastening system may comprise more fastening projections 16 and fastening receivers 17 than are shown in FIG. 1.

[0027] The fastening projections are shown in FIG. 1 in cross section. The fastening projections 16 extend with a uniform cross section in the longitudinal direction, oriented perpendicular to the sheet plane. The dimension of the fastening projections in the longitudinal direction, for example, may be five times or ten times as great as the width visible in FIG. 1 of the fastening projection. The fastening projections 17 in this manner cover a rectangular surface on the component 14 with a uniformly repeating structure.

[0028] Correspondingly, on the surface of the second component 15 a rectangular surface is covered by fastening projections 18 and fastening receivers 19. The shape of the fastening projections 18 and the fastening receivers 19 of the second component 15 are identical to the fastening projections 16 and the fastening receiver 17 of the first component 14. If the first component 14 in FIG. 1 were reflected on a horizontal line and pushed slightly to the side, it would cover the second component 15 in an identical manner.

[0029] The shape of the fastening projections 18 and the fastening receivers 19 is described in more detail with reference to the enlarged view of FIG. 3. Accordingly, the fastening projections 18 are symmetrical in cross section with a compression slot 20 which is arranged centrally and extends into the depth of the fastening projection 18. At its lower end the compression slot 20 terminates in a semi-circular shaped contour.

[0030] A first circular segment-shaped portion r1 with a first radius adjoins the compression slot 20. The first circular segment-shaped portion merges into a second circular segment-shaped portion r2 with a second radius, wherein the radius r2 is smaller than the radius r1. Together, the first and the second circular segment shaped-portion form a convex part of the contour of the fastening projection 18. A concave part of the contour of the fastening projection 18 adjoins this convex part. This is formed from a third circular segment-shaped portion r3, which adjoins directly the second circular segment-shaped portion. The third circular segment-shaped portion r3 has a third radius which is as large as the radius r2. A fourth circular segment-shaped portion r4 adjoins the third circular segment-shaped portion r3, said fourth circular segment-shaped portion having a fourth radius. The radius r4 is as large as the radius r1. The fourth circular segment-shaped portion r4 forms at the same time the center of the adjacent fastening receiver 19.

[0031] In this manner, a shape of the fastening projection 18 is produced which is complementary to the fastening receiver 19. If FIG. 3 were to be reflected on the horizontal line which extends through the transition between the second circular segment-shaped portion and the third circular segment-shaped portion and displaced slightly to the side, the fastening projections 18 and the fastening receiver 19 would be covered in an identical manner apart from the compression slots 20.

[0032] The widest point of the fastening projection 18 is formed by the second circular segment-shaped portion r2. The second circular segment-shaped portion r2 extends beyond the widest point and thus forms a portion in which the fastening projection 18 tapers again. Relative to the direction of insertion, this tapering forms an undercut which may be engaged from behind by the fastening projections of the other component.

[0033] If the components 14, 15 were to be guided together from the position shown in FIG. 1, the fastening projections 16 of the first component 14 would engage in the fastening receiver 19 of the second component 15 and vice versa. The widest point of the fastening projections 16 is slightly wider than the narrowest point of the fastening receiver 19 so that the two may be brought into engagement with one another without resistance. If the two components 14, 15 are pressed together, via the outer surfaces a force is exerted in the transverse direction onto the fastening projections 16, 18, the fastening projections 16, 18 being compressed thereby in the transverse direction.

[0034] In this compressed state, the widest points of the fastening projections 16 are able to pass the widest points of the fastening projections 18, so that a full engagement with the respectively opposing fastening receivers 17, 19 is achieved. The fastening projections 16, 18 relax again so that the widest points engage behind one another. The connection between the components 14, 15 may be produced in this manner without regions of the components 14, 15 other than the fastening projections 16, 18 having to be deformed.

[0035] In order to separate the two components 14, 15 again from one another, a force is exerted in the opposing direction. As a result, the fastening projections 16, 18 are compressed again, so that the widest points may be overcome. The force expenditure required therefor corresponds substantially to the force expenditure when producing the connection.
