DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS

(11) FIG. 1 shows a flat part 2, which has a longitudinal extent along a Y-axis 4 and a transverse extension along an X-axis 6. The end face edges 8 run parallel to the X-axis 6. The longitudinal edges 10 run parallel to the Y-axis. A first recess 14 is provided in the wide surface 12 of the flat part.

(12) The recess 14 can be formed as a oblong hole. The extent of recess 14 along the Y-axis 4 is preferably greater than the extent of recess 14 along the X-axis 6. The dimensions of recess 14 are such that the extents in the directions of X-axis 6 and Y-axis 4 are greater than the maximum tolerances of a bolt on an attachment part.

(13) A tolerance slider 16 as shown in FIG. 2a, b can be slid onto the flat part 2 as shown in FIG. 1. A top view of a tolerance slider 16 is shown in FIG. 2a. The tolerance slider 16 has an extent along the X-axis 6 which is either slightly larger than the extent of the flat part 2 along the X-axis 6 or corresponds to the extent of the recess 14 along the X-axis 6. In the first case, the tolerance slider 16 can be provided with outer arms 18, as shown in FIG. 2b, which can embrace the flat part 2 along the longitudinal edges 10. In the latter case it is possible that the tolerance slider 16 is inserted into the recess 14. Both will be shown below.

(14) A recess 20 is provided in the tolerance slider 16. The recess 20 preferably has the same extent along the X-axis 6 as the recess 14, but can also be reduced by the dimension of the webs 22, which limit the recess 20 in the direction of the longitudinal edges 24.

(15) In the y-direction 4, recess 20 has a smaller extent than recess 14. In particular, the extent of recess 20 in the direction of the y-axis 4 is preferably only slightly larger than a diameter of a bolt.

(16) The arms 18 can be c-shaped in order to e.g., completely embrace the flat part 2 along the longitudinal edges 10 and, if necessary, to grip behind it or to engage in a groove arranged on a side surface.

(17) Bolts, to which a tolerance compensation according to the subject-matter is to be attached, can have different shapes. FIGS. 3a and b show examples of such different shapes. For example, a bolt 26 can have a diameter 26c. This is shown in FIG. 3a.

(18) FIG. 3b shows that a bolt 26 can also have a rectangular or square cross-section. Other polygonal cross-sections are also possible. The longitudinal extent 26a and the transverse extension 26b can, for example, be decisive for the size of recess 14 and 20. In particular, recess 14 in Y axis 4 is larger than the transverse extent 26a. The recess 14 is larger along the X-axis 6 than the transverse extent 26b. The recess 22 preferably is, along the Y-axis 4, as large as or only slightly larger than the longitudinal extension 26a. The recess 20 is preferably larger along the X-axis 6 than the transverse extension 26b.

(19) To attach the flat part 2 to a bolt 26, it is placed on a bolt 26 as shown in FIGS. 4-8.

(20) FIGS. 4a, b show a fastening of a flat part 2 to a bolt 26, where the bolt 26 has a deviation from its target position in the image plane to the right and downwards.

(21) The tolerance slider 16 can be moved along the Y-axis 4 on the flat part 2. The displacement direction 28 corresponds to the orientation of the Y-axis 4. To fix the flat part 2 to the bolt 26, the recess 14 is placed over the bolt 26 and the bolt 26 is pushed through the recess 14. At the same time, the tolerance slider 16 is positioned along the displacement direction 28 on the flat part 2 in such a way that the bolt 26 can also be inserted through the recess 20. It can be seen that the bolt 26 is received by the tolerance slider 16 in such a way that the recess 20 touches the bolt 26 in close contact, especially along the Y-axis 4. Thus, the bolt 26 can for example be screwed to the flat part 2 by means of a screw connection.

(22) In FIG. 4b it can be seen that the bolt 26 is displaced from the target position 30 to the right. Furthermore it can be seen that the tolerance slider 16 engages with its arms 18 in a groove 2a of the flat part 2 on the side faces of the flat part 2.

(23) FIG. 5a shows a further embodiment in which the bolt 26 is shifted to the left and upwards in relation to the target position 30. Here too, the extent of recess 14 ensures that the bolt 26 can be inserted into recess 14 without any problems. The flat part 2 can remain in the target position 30, although the bolt 26 has a tolerance in relation to it. By shifting the tolerance slider 16 along the shifting direction 28, the bolt 26 can be positioned in the recess 20.

(24) FIG. 5b also shows a positioning of the bolt 26 deviating from a target position 30.

(25) FIG. 6 shows a side view of a tolerance compensation according to FIG. 5a. It can be seen how the arms 18 engage in the groove 2a. The groove 2a extends along the recess 14.

(26) FIG. 7a shows a flat part 2, which has a slot 32 in the area of the front face edge 8. The slot 32 extends from the front face edge 8 to the recess 14. Due to the slot 32 it is possible to elastically deform the flat part 12 in the area of the recess 14 in the direction of the X-axis 6. This can be particularly advantageous if the tolerance slider 16 is to be pushed onto the flat part 2.

(27) In FIG. 7b it can be seen that the tolerance slider 16 has been pushed onto the flat part 2. Here, for example, the slot 32 can serve to compress the front face edge 8 so that the tolerance slider 6, which embraces the flat part 2 with its arms 18, can be pushed onto the flat part 2. The slot 32 is then widened again by the restoring force of the flat part 2, so that the tolerance slider 16 can be held at the flat part 2, for example in a clamped manner. The positioning of the bolt 26 in the recesses 14, 20 according to FIG. 7b is carried out as shown in FIG. 4a.

(28) Subsequently, a fixing of the bolt 26 follows, as shown in FIG. 7c. For this purpose, a nut 34, for example, is screwed onto the bolt 26. Via a washer not shown, the nut 34 can be pressed onto the tolerance slider 16. This fixes the flat part 2 and the tolerance slider 16 to the bolt 26 and to the attachment part to which the bolt 26 is attached.

(29) FIG. 8 shows a further embodiment in which the tolerance slider 16 is guided in the recess 14. It can be seen that the tolerance slider 16 is guided with its longitudinal edges 24 on the inside longitudinal edges of recess 14. For this purpose, the tolerance slider 16 can engage in grooves within the inner surfaces of recess 14, for example. The tolerance slider 16 can also embrace the longitudinal edges of recess 14. A positioning of the bolt 26 in the recesses 14, 20 is carried out in such a way that the tolerance slider 16 is shifted in shift direction 28 in the recess 14 so that it is aligned with the bolt 26. Then the bolt 26 can be pushed through the recess 20 and thus through the recess 14 and can be fixed, for example, with a nut, as shown in FIG. 7c, to the tolerance slide 16.

(30) FIG. 9 shows a further embodiment in which a flat cable 36 is assembled. The flat cable 36 can, for example, be designed as a double flat cable and be made up of flat parts lying one above the other. The double flat cable can be connected with the battery positive pole on the one hand and the battery negative pole on the other hand. Taps can be provided at different positions along the flat cable 36. Thus, two or more taps are possible. These taps can, for example, be welded onto the flat cable 36 and protected by means of coupling boxes 38.

(31) The flat cable 36 can be bent around different axes, especially around the longitudinal axis of the flat cable 36 and/or the transverse axis of the flat cable 36 and/or an axis perpendicular to the drawing plane.

(32) The Coupling Boxes 38 can be provided for fastening with coarse threaded bolts 26. For this purpose, tolerance compensations with flat part 2 and tolerance slider 16 are provided on the coupling boxes 38. One or more tolerance compensations can be provided at a coupling box 38.

(33) The bolts 26 are welded to the body subject to tolerances. In order to avoid that the flat cable 36 has to be bent when fixing it, the tolerance compensations according to the subject-matter are provided. At each of the tolerance compensations, a tolerance of a bolt 26 can be compensated by moving the tolerance slide 16 along the flat part 2. Thus, the flat cable 36 or the coupling boxes 38 can be attached to the bolts 26 without mechanical tensions occurring on the coupling boxes 38, the bolts 26 and the taps arranged in the coupling boxes 38.

(34) To fix the bolts 26 to the tolerance sliders, plastic nuts can be provided, for example, which can be tightened with a few Newton metres of slots.

(35) For example, two taps, one at a lower flat cable and one at an upper flat cable, can be provided at a coupling box 38, so that the double flat cable 36 can be tapped at its two potentials.
