DETAILED DESCRIPTION OF THE DRAWINGS

[0037] FIG. 1 shows a motorcycle 10 which is configured as a motorbike. The motorcycle has a body 12, a tank 14 and an adjustable seat assembly 16 which is attached to the motorcycle 10 behind the tank 14 in relation to a longitudinal direction of the motorcycle 10.

[0038] As an alternative to this, however, the tank 14 can also be provided at another location of the motorcycle 10, for example in the region of the rear of the motorcycle 10 or below the seat assembly 16.

[0039] FIG. 2 shows a seat assembly 16 in a side view. The seat assembly 16 has a seat pan 18, to which a seat cushion 20 is attached which is covered with a seat cushion cover 22. Here, the seat cushion 20 forms a seat face for a rider of the motorcycle 10 and possibly for a pillion passenger.

[0040] FIG. 3 shows the seat assembly 16 in a side view with a removed seat cushion 20. The seat pan 18 has a base shell 24 which is attached via a fastening section 25 fixedly and non-displaceably to the body 12 and/or to a frame part of the motorcycle 10. Furthermore, the seat pan 18 has an adjusting shell 26 which is placed onto the base shell 24.

[0041] The seat assembly 16 has an adjusting device 28 which connects the base shell 24 and the adjusting shell 26 and is configured to adjust a height and/or an inclination of the adjusting shell 26 with respect to the base shell 24.

[0042] The base shell 24 has three guide elements 30 which extend in each case through one of two through openings 32 which are provided in the adjusting shell 26. Any desired other number of guide elements 30 can also be provided, however. Here, the guide elements 30 bear on their lateral sections (as viewed in the longitudinal direction of the seat assembly 16) in each case against an inner wall of the corresponding through opening 32. Here, the two guide elements 30 prevent a lateral movement (as viewed in the longitudinal direction of the motorcycle 10) of the adjusting shell 26 with respect to the base shell 24.

[0043] The guide elements 30 further preferably run, starting from the base shell 24, in each case predominantly vertically, the guide elements 30 being inclined, in particular, toward the rear in each case in the longitudinal direction of the seat assembly 16 and enclosing an angle with the vertical of at most 45°, preferably at most 30°, further preferably at most 20°.

[0044] As an alternative, the guide elements 30 can also be configured as hinges and/or as pivot pins which are attached in each case to the base shell 24 and the adjusting shell 26, with the result that the base shell 24 and the adjusting shell 26 are connected to one another such that they can be moved relative to one another.

[0045] FIG. 4a shows the base shell 24 with an adjusting device 28 in accordance with a first embodiment in a plan view, the adjusting shell 26 being shown merely in part for illustration reasons. The adjusting shell 26 extends, however, substantially over the entire base shell 24.

[0046] The adjusting device 28 has a first shaft 34 and a second shaft 36 which are attached to the base shell 24 such that they are offset with respect to one another in the longitudinal direction of the seat assembly 16 and cannot be displaced in each case with respect to the base shell 24, but can be rotated with respect to the base shell 24.

[0047] A first adjusting element 38 is attached fixedly to the first shaft 34 so as to rotate with it. In an analogous manner with respect to this, a second adjusting element 40 is attached fixedly to the second shaft 36 so as to rotate with it. In the embodiment which is shown, the two adjusting elements 38, 40 are configured in each case as toggle levers.

[0048] FIG. 4b shows the adjusting shell 26 in a view from below, the base shell 24 not being shown for illustration reasons, but the two shafts 34, 36 with the two adjusting elements 38, 40 being shown.

[0049] The first adjusting element 38 has a first contact point 42 with respect to the adjusting shell 26, whereas the second adjusting element 40 has a second contact point 44 with respect to the adjusting shell 26.

[0050] As illustrated diagrammatically in FIG. 5a, the first adjusting element 38 defines a spacing between the first shaft 34 and the first contact point 42 here, and therefore defines a local spacing between the base shell 24 and the adjusting shell 26. If the first shaft 34 is rotated, said spacing changes.

[0051] In an analogous manner with respect to this, the second adjusting element 40 defines a spacing between the second shaft 36 and the second contact point 44, and therefore defines a local spacing between the base shell 24 and the adjusting shell 26. If the second shaft 36 is rotated, said spacing changes.

[0052] Since the two shafts 34, 36 are offset with respect to one another in the longitudinal direction of the seat assembly 16, the height and/or the inclination of the adjusting shell 26 with respect to the base shell 24 can be set by way of rotation of the two shafts 34, 36.

[0053] The two shafts 34, 36 can preferably be rotated independently of one another, with the result that both the height and the inclination of the adjusting shell 26 with respect to the base shell 24 can be set individually.

[0054] In particular, merely the height of the adjusting shell 26 is changed if the two adjusting elements 38, 40 are actuated at the same time in the same direction. If, in contrast, merely one of the two adjusting elements 38, 40 is actuated or if the two adjusting elements 38, 40 are actuated at the same time in different directions, the inclination of the adjusting shell 26 is changed.

[0055] In particular, the adjusting device 28 can be actuated mechanically and/or electrically. Accordingly, the adjusting device 28 comprises at least one electric motor 43 and/or a mechanical mechanism, by means of which at least one shaft, preferably the two shafts 34, 36, can be rotated.

[0056] The adjusting device preferably comprises two electric motors 43 which are connected in each case in a torque-transmitting manner to one of the shafts 34, 36 and are configured to rotate the respective associated shaft 34, 36.

[0057] Here, the electric motors 43 can be actuated, without it being necessary for parts such as, for example, the seat cushion 20 to be removed from the seat assembly 16. For this purpose, the adjusting device 28 can have an actuating element which is accessible from outside the motorcycle 10, such as, for example, an actuating switch for the electric motors 43, which actuating switch can be arranged on a dashboard and/or on handlebars of the motorcycle 10.

[0058] The adjusting device 28 can comprise a locking device which is configured to release and/or to lock the height and/or inclination adjustment of the adjusting shell 26. In the above-described embodiment, the locking device can be formed, for example, by way of the electric motors 43 themselves which can be operated in a locking mode, in which they prevent the rotation of the two shafts 34, 36.

[0059] The motorcycle 10 can optionally have a control unit 45 (FIG. 1) which is configured to actuate the adjusting device 28 automatically in a manner which is based on operating parameters of the motorcycle 10, in particular in a manner which is based on a speed of the motorcycle 10.

[0060] For example, the control unit actuates the adjusting device 28 in such a way that the adjusting shell 26 has a lower inclination and/or a lower height at low speeds, in particular when starting, than at higher speeds.

[0061] The height of the seat face is preferably reduced at low speeds, in particular when the motorcycle 10 is stopping, with the result that the rider can reach the ground with his/her legs more easily.

[0062] Further preferably, the inclination of the seat face is increased as the speed increases and/or in the case of pronounced acceleration, that is to say if the acceleration exceeds a predefined limit value, with the result that the rider requires less force, in order to hold onto the motorcycle 10 firmly counter to the increasing wind resistance.

[0063] In the following text, further embodiments of the seat assembly 16 will be described, largely functionally identical components bearing the same designations. Here, merely the differences with respect to the above-described embodiment will be described in the following text.

[0064] FIG. 5b diagrammatically shows a second embodiment of the adjusting device 28, in the case of which the first adjusting element 38 is configured as a cam.

[0065] The fundamental method of operation is the same as described above, however. The first adjusting element 38 defines a spacing of the first shaft 34 with respect to the first contact point 42, said spacing changing in the case of a rotation of the first shaft 34 on account of the non-round contour of the cam. In an analogous manner with respect to this, the second adjusting element 40 can also be configured as a cam.

[0066] FIGS. 6 and 7 show a third embodiment of the seat assembly 16 in an oblique view, in the case of which the two shafts 34, 36 and the two adjusting elements 38, 40 in accordance with the above-described embodiments are replaced by a first adjusting element 38′ and a second adjusting element 40′, the two adjusting elements 38′, 40′ being configured in each case as a pneumatically and/or hydraulically actuable fluid cushion.

[0067] The two adjusting elements 38′, 40′ are attached fixedly and non-displaceably to the base shell 24 in a manner which is offset with respect to one another in the longitudinal direction of the seat assembly 16.

[0068] Here, the two adjusting elements 38′, 40′ are of substantially rectangular configuration and extend in each case transversely with respect to the longitudinal direction of the seat assembly 16.

[0069] On their upper side, the first adjusting element 38′ and the second adjusting element 40′ have a first contact face 46 and a second contact face 48, respectively, with respect to the adjusting shell 26.

[0070] In addition, the adjusting device 28 comprises a first pump 50 and a second pump 52 which are connected in a fluid-conducting manner to the first adjusting element 38′ and the second adjusting element 40′, respectively. The two pumps 50, 52 are configured to pump a fluid into the respective adjusting element 38′ and 40′, respectively, and/or to pump the fluid out of the respective adjusting element 38′ and 40′, respectively.

[0071] The adjusting elements 38′, 40′ extend, starting from the base shell 24, in each case over a defined height, depending on how much air and/or liquid are/is situated in the fluid cushions. Accordingly, the height and/or the inclination of the adjusting shell 26 with respect to the base shell 24 can be adjusted by the fact that air and/or liquid are/is pumped into the adjusting elements 38′, 40′ or are/is discharged from the adjusting elements 38′, 40′. Here, the height and/or the inclination of the adjusting shell 26 with respect to the base shell 24 is greater, the more air and/or liquid are/is situated in the fluid cushions.

[0072] If the fluid is air, one-way operation of the pumps 50, 52 is also conceivable, with the result that the pumps 50, 52 are configured merely to pump air into the fluid cushions. In order to discharge the air again, a discharge valve 54 can be provided in each case on the adjusting elements 38′, 40′.

[0073] For example, the adjusting device 28 comprises two electric motors which are assigned in each case to one of the pumps 50, 52 and are configured to actuate the respective associated pump 50, 52.

[0074] The adjusting device 28 comprises a locking device which is configured to release and/or to lock the height and/or inclination adjustment of the adjusting shell 26. For example, the locking device is formed by way of control valves 56, the first pump 50 and the second pump 52 being assigned in each case one control valve 56. The control valves 56 are configured to release and/or to lock a fluid flow into the two adjusting elements 38′, 40′ and/or out of the two adjusting elements 38′, 40′.

[0075] In all above-described embodiments, only one of the two adjusting elements 38, 40 or 38′, 40′ can of course also be provided. Depending on the arrangement of said one adjusting element, the height and/or the inclination of the adjusting shell 26 with respect to the base shell 24 can then be adjusted.
