DETAILED DESCRIPTION OF THE DRAWINGS

[0024] FIG. 1 shows a part of a motor vehicle 10 in a sectional view in the XZ-plane of the motor vehicle 10 with a viewing direction in the Y-direction of the motor vehicle 10. The motor vehicle 10 has a vehicle body 20. Within the context of this invention, the vehicle body 20 also comprises a tailgate 20.1. A receptacle 22 is arranged in the vehicle body 20, in which receptacle 22 a vehicle part 30 is received. FIGS. 1 to 4 show a rear light by way of example as a vehicle part 30.

[0025] The vehicle part 30 is fastened in the receptacle 22 with the aid of a spring bolt 40. FIG. 1 shows that a threaded bolt 42 of the spring bolt 40 can be arranged, for example, on the vehicle part 30. As FIG. 1 also shows, other known constituent parts of the spring bolt 40 can be arranged in an opening of the receptacle 22, such as, for example, a spring 44, a housing with a thread 46, etc. Before the insertion of the vehicle part 30, the spring bolt 40 is not prestressed. The spring bolt 40 is arranged, for example, in the bottom of the receptacle 22.

[0026] FIG. 2 shows the vehicle part 30 which is fastened in the receptacle 22 by way of the spring bolt 40 in the view from FIG. 1. As can be seen in FIGS. 1 and 2, the rotational axis D of the spring bolt 40 is arranged in such a way that it has precisely one point of intersection S with an XY-plane of the motor vehicle 10. As a result, the rotational axis D of the spring bolt 40 always has an angle of intersection a with an XY-plane of the motor vehicle 10. Therefore, according to the invention, the rotational axis D of the spring bolt 40 is not arranged parallel to an XY-plane of the motor vehicle 10 or in an XY-plane of the motor vehicle 10.

[0027] The axial force F of the spring bolt 40 along the rotational axis D can likewise be seen in FIG. 2. By virtue of the fact that the rotational axis D of the spring bolt 40 has precisely one point of intersection S with an XY-plane of the motor vehicle 10, at least one part Fz of the axial force F which results from the spring bolt 40 acts in the receptacle 22 in the Z-direction of the motor vehicle 10. As a result, the vehicle part can be pulled particularly satisfactorily against the top in the Z-direction of the receptacle 22, and the tolerance can be reduced to a very small value.

[0028] Here, the vehicle part 30 preferably has at least one Z-rest 32, by way of which the vehicle part 30 bears in the receptacle 22 in the Z-direction and via which the force Fz is transmitted to the vehicle body 20. The vehicle part 30 particularly preferably has two Z-rests 32.

[0029] FIG. 2 also shows by way of example a part Fx of the axial force F which results from the spring bolt 40 in the X-direction of the motor vehicle 10. The force Fx pulls the vehicle part 30 at the same time onto the bottom of the receptacle 22, as a result of which the tolerance in said direction can likewise be reduced to a very small value.

[0030] Here, the vehicle part 30 preferably has at least one X-rest 34, by way of which the vehicle part 30 bears in the receptacle 22 in the X-direction and via which the force Fx is transmitted to the vehicle body 20. The vehicle part 30 particularly preferably has three X-rests 32.

[0031] Therefore, in summary, the vehicle part 30 is mounted and held in a sprung manner in the receptacle 22 by way of the spring bolt 40. Here, tensile forces of the spring bolt 40 in the range of 400 N or more are preferably used. Here, tensile forces of 500 N±50 N are particularly preferred.

[0032] FIG. 3 shows the rear side of the vehicle part 30. The vehicle part 30 has by way of example three X-rests 34 which are preferably configured as cross ribs. Moreover, the vehicle part 30 has two Z-rests 32 which are configured as flat elements. Parts of the spring bolt 40 are likewise depicted in FIG. 3.

[0033] Therefore, a force equilibrium in two planes and over five points (three X-rests, two Z-rests) is achieved by way of the arrangement according to the invention of the spring bolt 40 in this embodiment. Here, said five points are sufficient to achieve particularly satisfactory orientation and fastening only with the aid of the spring bolt 40 which is oriented according to the invention.

[0034] Furthermore, FIG. 3 depicts a seal 50 which, in the installed state, is arranged between the receptacle 22 and the vehicle part 30. The seal 50 is preferably formed from a foamable material. The seal 50 is compressed during the tightening of the spring bolt 40. Moreover, the vehicle part 30 is oriented particularly satisfactorily in the seal 50 during the tightening of the spring bolt 40.

[0035] The spring bolt 40 is particularly preferably arranged at the centroid position of the seal 50 and/or the rests 32 and 34. As a result, particularly satisfactory orientation and fastening of the vehicle part 30 in the receptacle 22 are achieved.

[0036] Moreover, FIG. 3 depicts a Y-setting pin 36 which is arranged on the vehicle part 30. The Y-setting pin 36 serves for the additional orientation of the vehicle part 30 in the Y-direction of the motor vehicle 10.

[0037] FIG. 4 shows the vehicle body 20 with the receptacle 22 for receiving the vehicle part 30 in an outside view of the vehicle body 20. Here, the vehicle body 20 is configured by way of example as a tailgate 20.1.

[0038] In FIG. 4, three X-rest receptacles 34.1 and one Y-setting pin receptacle 36.1 are arranged in the bottom of the receptacle 22. In general, the receptacles receive the corresponding rests or pins, and facilitate the orientation of the vehicle part 30.
