DETAILED DESCRIPTION OF THE INVENTION

[0037] A device 1 according to the present invention comprises a rotation unit 2, a sliding unit 3, a locking element 4, as well as an operating lever 5, for example, (FIGS. 1 to 9).

[0038] The rotation unit 2 is advantageously composed of a base plate 6 and a turntable 7. The base plate 6 is configured, for example, to be fixed in position and mounted on a vehicle (not shown), e.g., on a substructure of a vehicle seat. The turntable 7 is mounted on the base plate 6, for example, rotatable about an axis of rotation D. The base plate 6 has, for example, a circular opening 8, especially a cylindrical one, in an area around the axis of rotation D. The turntable 7 has, for example, a circular opening 28, especially a cylindrical one, in an area around the axis of rotation D. Advantageously, a diameter of the opening 28 is as large as or larger than a diameter of the opening 8. The base plate 8 advantageously borders the opening 8 with a peripheral edge 9, such as a circular one, especially a cylindrical one. In the area of the peripheral edge 9, latching mechanism is formed on the base plate 8 in the form of cut-outs 10, 11. The cut-outs 10, 11 are advantageously present in such a way that they interrupt the circular and/or cylindrical contour of the peripheral edge 9, for example, or increase its diameter.

[0039] For example, the operating lever 5 is rotatably or pivotably mounted on the turntable 7 on a mount 12 of the turntable 7. The operating lever 5 is advantageously angled in configuration, with a, for example, relatively long lever arm 13, on which a handle 14 is present for working the operating lever 5 by the user, and a, for example, relatively short lever arm 15 making an angle with this. Advantageously the locking element 4 is formed on the lever arm 15. The two lever arms 13, 15 are preferably joined together at a connection point 16. For example, the operating lever 5 is mounted on the mount 12 at the connection point 16, especially in rotatable manner.

[0040] The sliding unit 3 has, for example, a first sliding piece 17 and a second sliding piece 18.

[0041] Advantageously, the first and the second sliding piece 17, 18 are slidable relative to each other, especially in linear manner, on the sliding unit 3. Preferably the first sliding piece 17 is firmly joined to the turntable 7 of the rotation unit 2, e.g., screwed, welded, and/or riveted. In this way, the sliding unit 3 can rotate relative to the base plate 6. In particular, in the mounted condition of the device 1 on the vehicle, the sliding unit 3 is in this way rotatably mounted on the vehicle.

[0042] The first sliding piece 17 advantageously comprises, for example, a circular, in particular, cylindrical opening 19. The opening 19 especially in one diameter is precisely as large, advantageously larger in configuration than the opening 8 of the rotation unit 2. It is also conceivable that the first sliding piece 17 is framelike, while distances between mutually facing sides of the frame are advantageously larger than the diameter of the openings 8, 28 of the rotation unit 2 and the sliding unit 3 is mounted on the rotation unit 2 in such a way that the frame of the first sliding piece 17, looking from a top view onto the device 1, is not present above the openings 8, 19 or the frame sides are present at a distance from the peripheral edge 9 toward the outside in the radial direction. It is further conceivable that the first sliding piece 17 comprises two rail elements 22, 23, on which the second sliding piece 18 is arranged, especially in a linearly slidable manner. Advantageously, the two rail elements 22, 23 are oriented parallel to each other. The two rail elements 22, 23 are advantageously spaced apart from each other in such a way that the spacing of the rail elements 22, 23 is larger than a largest diameter of an opening 8, 19.

[0043] The second sliding piece 18 advantageously comprises a mounting device, on which a vehicle seat (not shown) can be secured. In the mounted condition, the vehicle seat and the second sliding piece 18 are advantageously joined together in fixed position. In this way, for example, a vehicle seat is connected both rotatably and displaceably to the base plate 6 or to a vehicle.

[0044] The second sliding piece 18 is likewise advantageously framelike. Ideally, a frame of the second sliding piece 18 corresponds in its dimensions to dimensions of the frame of the first sliding piece 17. For example, the second sliding piece 18 comprises in addition a lengthwise brace 21. The lengthwise brace 21 is configured, for example, in such a way and the sliding unit 3 is advantageously arranged on the rotation unit 2 in such a way that the lengthwise brace 21, especially in every position of the device 1, forms a secant to the two openings 8, 19. For example, the lengthwise brace 21 is present on the sliding unit 3 parallel to the rail elements 22, 23 of the first sliding piece 17 and is formed, for example, between sides of the frame of the second sliding piece 18. On the second sliding piece 18, a holding mechanism is present, for example, in the form of a cut-out 20 in the region of the edge 24 on the lengthwise brace 21.

[0045] Advantageously, in every displacement or rotation position of the device 1, an edge 24 of the lengthwise brace 21 looking in a top view onto the device 1 forms a tangent to the opening 8 or a tangent to a circular arc of the opening 8, especially a tangent to the peripheral edge 9 of the opening 8. Preferably, looking in a top view, one point of the edge 24 of the lengthwise brace 21 and one point of a longitudinal axis of the lengthwise brace 21 situated on a normal to the edge 24 or the longitudinal axis of the lengthwise brace 21, the normals extending through the axis of rotation D, are present at the same spacing in every rotational or sliding position of the device 1 with respect to the peripheral edge 9 of the base plate 6 or the circular arc of the opening 8 of the base plate 6, this spacing being called hereafter the radial spacing. Advantageously, this radial spacing from the edge 24 to the peripheral edge 9 of the base plate 6 is zero, i.e., looking from the top view onto the device 1, the edge 24 or the lengthwise brace 21 is tangent to the peripheral edge 9 or the circular arc of the opening 8, for example.

[0046] Advantageously, both the latching mechanism and the holding mechanism are present in such a way that the locking element 4 can be positioned to engage with the latching mechanism or the holding mechanism, so that the locking element 4 looking in a top view onto the device 1 is not intersected by the circular arc of the opening 8 or the longitudinal axis of the edge 24 of the lengthwise brace 21.

[0047] The locking element 4 is formed, in particular, as a cylindrical bolt, for example. The bolt is advantageously arranged on the operating lever 5 in such a way that a longitudinal axis of the bolt is present perpendicular to a plane of movement of the operating lever 5. For example, the bolt in every position on the device 1 engages either with a latching mechanism, e.g., with the cut-out 10 or with the cut-out 11, and/or with a holding mechanism, e.g., with the cut-out 20.

[0048] Advantageously, the bolt is present such that it can be arranged to abut by a first outer region in the mounted condition against the latching mechanism or against a surface of the latching mechanism and it can be arranged to abut by a second outer region, which is present opposite the first outer region in the radial direction looking toward the axis of rotation D, against the holding mechanism or against a surface of the holding mechanism.

[0049] If the bolt engages in one position with a holding mechanism, a rotation range of the turntable 7 relative to the base plate 6 will be limited. Conversely, if the bolt engages in one position with a latching mechanism, a displacement range of the second sliding piece 18 relative to the first sliding piece 17 or to the base plate 6 will be limited. If the device is present, e.g., in such a way that the bolt engages in one position with both a latching mechanism and a holding mechanism at the same time, both a rotation range and a displacement range will be limited.

[0050] In the following, various movement positions of the device 1 will be described as an example with FIGS. 1 to 9.

[0051] In FIGS. 1 and 2, the bolt is situated engaging with the cut-out 10. In this way, a rotational movement of the turntable 7 and thus of the sliding unit 3 relative to the base plate 6 is blocked. In this position, the cut-out 10 surrounds the bolt advantageously with form fitting, such that the bolt is hindered by the cut-out 10 in a rotating direction about the axis of rotation D (FIG. 2). FIG. 2 shows the sliding unit 2 transparent relative to the base plate 6 in a top view onto the device 1, for better comprehension. In this way, it can be seen that the turntable 7 is secured by the bolt in the cut-out 10 relative to the base plate 6 and that the second sliding piece 18 of the sliding unit 3 can move slidably past the bolt.

[0052] In FIGS. 3 and 5, the second sliding piece 18 has been displaced relative to the base plate 6 in such a way that the bolt can be pivoted into the cut-out 20 by a movement of the operating lever 5. FIG. 4 in addition shows that the bolt is led advantageously by a guide element in the form of a guide plate 25. For this, the guide plate 25 comprises e.g. a slotlike cut-out 26, in which the bolt is led along the pivoting movement dictated by the operating lever 5. The cut-out 26 advantageously has a stop surface 27, against which the bolt abuts in the maximum pivoted condition. This prevents a skewing or jamming of the device 1 or the operating lever 5.

[0053] If the bolt has been pivoted into the cut-out 20 (FIG. 6), the second sliding piece 18 can be displaced along the lengthwise brace 21, relative to the base plate 6, according to the size of the cut-out 20, especially according to the length of the cut-out 20. For this, the cut-out 20 has e.g. two mutually facing end stops, against which the bolt abuts when the second sliding piece 18 is moved by a user. This defines a sliding range of the sliding unit 3. At the same time, a rotation of the turntable 7 relative to the base plate 6 is free, so that the sliding unit 3 and thus, for example, the mounted vehicle seat can rotate relative to the base plate 6.

[0054] FIG. 7 shows how the sliding unit 3 has been rotated relative to the base plate 6 such that the cut-out 20 and the cut-out 11 are adjacent to each other. In this way, the operating lever 5 can be pivoted, so that the bolt can be pivoted out from the cut-out 20 of the second sliding unit 18 into the cut-out 11 of the base plate 6.

[0055] In the movement position of the bolt in the cut-out 11, the sliding unit 3 is once again freely movable relative to the base plate 6 (FIGS. 8, 9), while a rotation range of the turntable 7 relative to the base plate 6 is limited by the cut-out 11.
