DETAILED DESCRIPTION
(10) In the figures, the same components are denoted by the same reference numerals, it being possible for the reference numerals to be omitted in some figures for clarity.
(11) FIG. 1 shows a vehicle seat element 1 in a perspective view, a first fastening eye 3 being arranged on the vehicle seat element 1. In particular, a fastening element 14 can be provided, by means of which the first fastening eye 3 is connected to the vehicle seat element 1. In this case, the fastening eye 3 is cylindrical and has an outer surface 15 and an inner surface 16. In particular, the first fastening eye 3 is circular in a cross section with a cylinder ring having a finite extent. It can also be seen that the first fastening eye 3 has grooves 9 into which the projections 7, 8 of the fastening eye insert 4 of the residual spring travel adjustment device 2 can engage. The arrangement and the configuration of the projections 7, 8, as well as the grooves 9, are shown in more detail in the following figures. Furthermore, the fastening eye insert 4 has an eccentric hole 5, that is, the hole is not located centrally in the fastening eye insert 4, but is displaced by a certain distance with respect to the centre of the fastening eye insert 4. The centre of the fastening eye insert 4 can be formed, for example, by the central axis or axis of rotation.
(12) FIG. 2 shows the vehicle seat element 1 in a side view. As can be seen, the fastening eye 3 has a total of 4 grooves 9, 9′, 9″ and 9″, the grooves being arranged in pairs, that is, the grooves 9 and 9′ are arranged oppositely in the radial direction of the fastening eye 3 and the next pair of grooves 9″ and 9m are also arranged oppositely. Furthermore, the first pair of grooves 9, 9′ and the second pair of grooves 9″, 9″ are offset by an angle 17. In this case, the angle 17 is, according to a preferred embodiment, 90°. If the fastening eye insert is inserted into the first fastening eye 3, the projections 7, 8 engage in a pair of grooves 9, 9′ or 9″, 9″. In the present case, the projections 7, 8 engage in the grooves 9″ and 9m. If the fastening eye insert 4 is removed from the fastening eye 3 and subjected to rotation, preferably to the left or right in the circumferential direction 6, and then introduced back into the fastening eye 3, in particular into a pair of grooves 9, 9′, 9″, 9″, the eccentric hole 5 will also have been rotated in the circumferential direction. Accordingly, three different states are recognisable, the first state being shown in FIG. 2, the first state in this case describing the fact that the eccentric hole is located closest to the vehicle seat element 1. Another state, in particular the second state, describes a central position of the eccentric hole. In this case, the projections 7, 8 are in contact with the grooves 9, 9′. Furthermore, a third state is possible, the first state, in which the projections 7, 8 engage in the grooves 9″ and 9″, likewise engaging in the same grooves 9″, 9″ again, the grooves 7, 8, however, being rotated 180° in the circumferential direction 6. This third state describes the fact that the eccentric hole 5 is now farthest from the vehicle seat element 1.
(13) As can also be seen from FIGS. 1 and 2, the projections 7, 8, as well as the grooves 9, 9′, 9″, 9″ shaped complementarily thereto, have a defined width 18 or a defined depth 19.
(14) FIG. 3 shows a further embodiment of the fastening eye insert 4 being brought into contact with the first fastening eye 3. As can be seen, fine toothing 10 is formed between the fastening eye insert 4 and the first fastening eye 3. In particular, the fine toothing 10 is formed between the fastening eye insert 4 and the inner surface 16 of the first fastening eye 3. In this case, the fastening eye insert 4 can be displaced with respect to the first fastening eye 3, as shown in the embodiment in FIG. 2. First, the fastening eye insert 4 is removed from the first fastening eye 3 and subsequently rotated to the left or right in the circumferential direction 6 by a desired angle and then introduced back into the first fastening eye 3. In this case, the fine toothing 10 makes very precise adjustment of the position of the eccentric hole 5 possible.
(15) FIG. 4 shows a further embodiment, the fastening eye insert 4 being designed as a worm wheel 12 that is in contact with a worm 13, the worm 13 being connected to the first fastening eye 3 so as to be rotatable about a first axis of rotation 20. By actuating the worm, that is, by rotating the worm 13, the worm wheel 12 is driven and the fastening eye insert 4 is displaced to the left or right in the circumferential direction 6 relative to the first fastening eye 3. By rotating the worm wheel 12 by means of the worm 13, as well as according to the other embodiments, the eccentric hole 5 is displaced relative to the first fastening eye 3.
(16) The various essential states are shown again in FIGS. 5A, 5B and 5C. FIG. 5A shows the third state, in which the eccentric hole 5 is farthest away from the vehicle seat element 1. By contrast, FIG. 5C shows the first state, in which the eccentric hole 5 is located closest to the vehicle seat element 1. FIG. 5B shows an intermediate state in which the eccentric hole is located in a central position that is between the first state in FIG. 5A and the third state in FIG. 5C, in particular centrally between these states. These states can be taken up independently of the selected embodiment.
(17) FIG. 6 schematically shows an embodiment having a vehicle seat element 1. This is, in particular, a linear controller of the vehicle seat element 1, which is designed as a level controller according to the FIG. 6.
(18) Moreover, it is also conceivable that a second fastening eye is provided that also has a residual spring travel adjustment device 2 having a fastening eye insert 4. The embodiments of the second fastening eye as well as the residual spring travel adjustment device and the fastening eye insert can be designed in a similar way to the first fastening eye and as described above.
(19) All the features disclosed in the application documents are claimed as being essential to the invention, provided that, individually or in combination, they are novel over the prior art.
