[0052] FIG. 1 and FIG. 4 show an equipment part 10 for a vehicle, which comprises a base 11 and a pivot part 12. In the present embodiment, the equipment part 10 is an armrest with a base 11 fixed to the body, and the pivot part 12 is an arm support that can be pivoted relative to the base 11. The pivot part 12 forms a pivot joint 13 with the base 11 with the pivot axis a. Here, the base 11 is in the form of a retaining clip or U-shaped. The base 11 is formed by a sheet metal member having a central region 35, with end regions being angled forward at approximately right angles to the central region 35. Recesses 34 are arranged in the angled regions 36.

[0053] The pivot part 12 is pivotable about the pivot axis a relative to the base 11 between a first position and a second position. The first position (see FIGS. 1a, 1b, 2 and 3) is an approximately horizontal position in which a longitudinal central axis of the pivot part 12 is arranged e.g. parallel to or e.g. deviating by up to 30° from an x-axis. The x-axis is part of a common coordinate system comprising an x-axis, a y-axis and a z-axis according to FIGS. 1a and 1b.

[0054] In the second position (see FIGS. 4 and 5), the longitudinal center axis of the pivot part 12 is arranged approximately vertically, for example, i.e. parallel to the z-axis, or forms an angle of up to 30° with the z-axis, for example. Between the first position and the second position, the pivot part 12 in the present embodiment covers a pivot angle of about 90°. The pivot angle may deviate therefrom in other embodiments of the invention.

[0055] In this example, the pivot part 12 has an elongated shape, with the longitudinal extension being large with respect to width and height. A frame of the pivot part 12 includes side members 19a and 19b and a cross member 16 connecting the side members 19a and 19b. A housing or padding of the pivot part 12 is not shown in Figs.

[0056] A limitation of the movement of the pivot part 12 in the second position is effected by means of the traverse 16 which comprises opposite end regions 18a and 18b. The end portions 18a and 18b each move in a link 17 formed in the base 11. In the first position of the pivot part 12, an end portion 27 of the link 17 prevents movement in the direction u2 beyond the first position shown in FIG. 1. In the second position, there is also a stop, not shown, which in the second position prevents movement of the pivot part 12 beyond the second position in the direction u1.

[0057] The pivot part 12 comprises an end region 14 arranged near the base 11 and a free end region 15. In order to supply devices on the pivot part with power, for example, or in order to transmit data between devices arranged on the pivot part 12 and a vehicle unit, for example, a line 26 is routed between the base 11 and the pivot part 12. As a transition of the line 26 from the base 11 to the pivot part 12, the end region 14 is suitable, because here the movement of the pivot part 12 is small and the line 26 can be better protected against damage. Such a line 26 is formed, for example, by a metal cable or an optical fiber line.

[0058] In prior art devices, torsion and bending of the cable also occurred in this area, which could lead to damage to the cable under continuous load. According to the invention, such loads are prevented, which becomes clear from the following explanations.

[0059] According to the invention, the equipment part 10 comprises a guide device 20 for the line 26, which is shown in more detail as an assembly in FIGS. 6 to 12. In the present example, the guide device 20 is formed coaxially with respect to the pivot axis a. It comprises a base-fixed first part 21 and a second part 22 fixedly held to the pivot part 12. The second part 22 is pivotable relative to the first part 21.

[0060] A recess 24 is formed in the first part 21 coaxially with the central axis a, and a recess 25 is formed in the second part 22, likewise coaxially with the central axis a, through which an axle element 29 fixedly connected to the pivot part 12 passes. As can be seen in FIG. 4, the axle element 29 is mounted in a recess 34 of the base 11.

[0061] According to FIG. 7, a first portion 31 of the line 26 is connected to the first part 21 by a connection 28 and a second portion 32 of the line 26 is connected to the second part 22 by a connection 30. The connection 28 is located in the region of an axial opening 23 in the first part 21, and the connection 30 is located in the region of an axial opening 38 in the second part 22. The first portion 31 leads to the base 11 and the second portion 32 leads to the pivot part 12. Between the connection 28 of the first part 21 with the first portion 31 at and the connection 30 of the second part 22 with the second portion 32 at, a line store 33 (see FIG. 8) is formed in the form of an excess of the length of the line 26. The length of the line 26 in the line store 33 is constant.

[0062] In FIG. 8, it can be seen that the part 22 is designed as a pot-shaped housing and the part 21 is cover-shaped. An annular web 37 serves to center the part 21 on the part 22. In this way, the line store 33 is protected from external influences. Such influences can be, for example, mechanical effects. Damage is prevented in this way. Also, in this way the line 26 cannot interfere with the movement of the pivot part 12 or other movable parts. Furthermore, the line store 33 is accommodated by the housing parts 20 and 21 in such a way that it can assume different states.

[0063] In the present embodiment, the line 26 into the line store 33 is wound in a substantially spiral fashion. However, it can also be arranged differently according to an alternative embodiment. It is essential that the arrangement is such that, when the portion 32 moves relative to the portion 31, only slight deformations of the portions of the line 26 in the line store 33 are caused. In particular, a deformation should be evenly distributed over a long portion extending in the longitudinal direction of the line 26 in the line store 33.

[0064] In the present embodiment, in which the line store 33 comprises a spiral winding (see

[0065] FIG. 9b), the end portion 31 is closer to the pivot axis a than the end portion 32. When the first portion 21 moves relative to the second portion 22, the first portion 31 also moves relative to the second portion 32 (compare FIGS. 9b and 10b).

[0066] As an alternative to the spiral winding, a meandering laying of the line 26 can also be considered, for example.

[0067] According to FIGS. 9a and 9b, for example, the pivot part 12 is in the first position. For example, the arm support of an armrest is approximately in a horizontal position. When the pivot part 12 is pivoted in the direction u1, the second part 22 and the second portion 32 move with the pivot part 12 in the direction u1, while the first portion 31 and the first part 21 are immovable relative to the base 11. According to FIG. 9b, there are 2.25 turns of the line 26 in the line store 33. A radial gap S1 is formed between the turns.

[0068] In FIGS. 10a and 10b, the guide device 20 is shown in the second position of the pivot part 12. During the movement of the pivot part 12 in the direction u1 to the second position, the area 32 is rotated by about 90° in the direction u1 from the position according to FIG. 8. Referring to FIG. 10b, the line is wound with 2.5 turns, with the radial gap between the turns decreasing from S1 to the gap S2.

[0069] The line 26 experiences only a slight deformation per length section and is not twisted or kinked. Movement of the line takes place only within the guide device 20 and exclusively in the portion of the line 26 spirally wound around the center a, while the portions of the line located outside the guide device 20 are subjected to no deformation or only very slight deformation during movement of the pivot part 12. The service life of the line is thus considerably extended.

[0070] The larger the line store 33, i.e. the longer the line 26 located in the line store 33, the lower the deformation per length section of the line 26 during a movement of the pivot part 12.

[0071] During the reverse pivoting operation of the pivot part 12 from the second position in the direction u2 to the first position, the first part 21 and the second part 22 move to the relative position shown in FIGS. 9a and 9b, with the line store 33 assuming the position shown, in which the gap S1 between the line windings is established.

[0072] It should be noted that the gap S in this exemplary embodiment is only intended to indicate different winding states, which does not necessarily mean that the gap is constant over the entire winding.
