Fastening arrangement in a vehicle

Abstract

The invention relates to a fastening fixture for a motor vehicle, comprising a sheet metal part (7) on the car body and a U-shaped bracket (1) attached thereto that has a crossbar (2) with adjoining U-shaped legs (3) from the ends of which foot sections (5) extend at an angle and engage underneath the sheet metal part (7) on the car body and are especially welded to it. According to the invention, the sheet metal part (7) has cutouts (8) that are separate from each other and spaced at the same distance as the two U-shaped legs (3) of the bracket (1), and the foot sections (5) of the U-shaped legs (3) pass through said cutouts (8).

Claims

1. A fastening fixture for a motor vehicle, comprising: a sheet metal part on a body of the motor vehicle and a U-shaped bracket attached thereto, wherein the U-shaped bracket has a crossbar with adjoining legs that are spaced from each other by a distance and from ends of which foot sections extend at an angle and engage underneath the sheet metal part on the motor vehicle body, wherein the sheet metal part has cutouts that are separate from each other and are spaced at the spacing distance of the legs of the bracket, and the foot sections of the legs pass through said cutouts; and wherein the legs and the crossbar of the U-shaped bracket form a wire bracket plane, and the foot sections protrude from the legs in opposite directions with respect to the wire bracket plane.

2. The fastening fixture according to claim 1, wherein the bracket is made out of round stock, and wherein a cross section of both cutouts is larger than that of the round stock.

3. The fastening fixture according to claim 1, wherein the foot sections are bent away from the legs by a bending angle of 90.

4. The fastening fixture according to claim 1, wherein the foot sections are in a plane that is at a right angle relative to the wire bracket plane and/or are arranged parallel to each other.

5. The fastening fixture according to claim 1, wherein the foot sections are positioned in a staggered arrangement with respect to each other in which each foot section is slanted in a direction opposite to a direction of another leg, forming an acute angle with the wire bracket plane.

6. The fastening fixture according to claim 1, wherein, after the bracket has been fastened, the sheet metal part can be permanently connected to an adjoining structural part of the motor vehicle body.

7. The fastening fixture according to claim 1, wherein, when the sheet metal part is in a structural part of the motor vehicle body, the bracket is inserted directly into a structural part of the motor vehicle body.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The following is shown:

(2) FIG. 1 shows a U-shaped bracket made of round wire, in a stereoscopic depiction, with a crossbar, two U-shaped legs that protrude perpendicular from said crossbar, and two foot sections bent by 90 relative to said U-shaped legs;

(3) FIG. 2 shows the bracket in a side view;

(4) FIG. 3 shows the sheet metal part shown on its own as well with two circular-symmetrical cutouts for the insertion of the bracket; and

(5) FIG. 4 shows the fastening fixture with the bracket and the sheet metal part in the completely mounted state.

DETAILED DESCRIPTION OF THE INVENTION

(6) The bracket 1 shown in the figures is preferably made of a steel round wire having a defined diameter, and it has a straight crossbar 2, two U-shaped legs 3 that protrude perpendicularly from said crossbar and two foot sections 5 bent in opposite directions at an angle of 90. The length of the foot sections 5 can correspond approximately to the height of the U-shaped legs 3.

(7) As can be seen in FIG. 2, the U-shaped legs 3 and the crossbar 2 form a wire bracket plane E from which the foot sections 5 sections protrude in opposite directions from each other, that is to say, to both sides of the plane E. The foot sections 5 are bent away from the U-shaped legs 3 by a bending angle of 90 (FIG. 1) and are arranged parallel to each other.

(8) Moreover, the foot sections 5 in the figures are positioned in a staggered arrangement in which the foot sections 5 are at the positioning angle (FIG. 2) of approximately 15 to 60, especially of about 30 to 45, and are turned so as to be oriented parallel to each other inwards (in the direction of the middle of the crossbar 2). This means that each of the two foot sections 5 is slanted in the direction of the opposite U-shaped leg 3 and forms an acute positioning angle with the wire bracket plane E.

(9) In the flat sheet metal part 7 shown in FIG. 3, the bracket 1 is inserted into the position shown in FIG. 4 in a manner that will be described below.

(10) For this purpose, two circular-symmetrical cutouts 8 that are spaced at the same distance as the U-shaped legs 3 are machined into the sheet metal part 7 by means of stamping, drilling, etc. The diameters of the cutouts 8 are approximately 2 mm larger than the outer diameter of the round wire of the bracket 1.

(11) Moreover, the bending radii between the U-shaped legs 3 and the foot sections 5 are configured in such a way that the U-shaped legs 3 can be swiveled into the cutouts 8. The bracket 1 is inserted into the sheet metal part 7 as follows:

(12) First of all, the bracket 1 is oriented in such a way that one of its foot sections 5 is oriented slanted relative to the sheet metal part 7; the crossbar 2 here is tilted upwards at a slant.

(13) After the foot section 5 has been inserted into the cutout 8, the bracket 1 is swiveled around the bend between the inserted foot section 5 and the adjoining U-shaped leg 3, whereby the crossbar 2 moves outward, as indicated by the arrow 10 in FIG. 1.

(14) This causes the other foot section 5 (which has not yet been inserted) of the bracket 1 to be swiveled into the area of the associated cutout 8 in the sheet metal part so as to be inserted into said cutout 8.

(15) Then the U-shaped legs 3 can be set upright via the bends towards the foot sections 5 in the direction opposite to that indicated by the arrow 10, and the bracket 1 can be swiveled into its final position shown in FIG. 4.

(16) Subsequently, the foot sections 5 are integrally bonded to the sheet metal part 7, preferably by means of the familiar method of resistance projection welding (drawn lines 11).

(17) The sheet metal part 7 can be subsequently fastened at the prescribed position to the car body, for example, by means of spot-welded connections. Diverging from the embodiment shown, the sheet metal part 7 can be a structural part of the car body.
