Description

[0001] Seat device for a tilting vehicle

[0002] The invention relates to a seating device for a tilting vehicle.

[0003] Seating systems for tilting vehicles are known in which bench seats are detachably mounted on a supporting structure of the tilting vehicle. These are connected to the bench seat via a lock or a screw connection. With a screw connection, detaching the bench seat from the supporting structure of the tilting vehicle proves to be time-consuming. Using a lock that requires a key can also prove cumbersome if the key to open the lock is not carried or, due to extended use of the tilting vehicle, is no longer available to the user or can only be found after a lengthy search.

[0004] Furthermore, it has been found to be disadvantageous in the known seating devices that the locking devices used there are exposed to environmental influences due to the necessary accessibility from the outside, whereby the locking devices are exposed to contamination and / or corrosion of individual components.

[0005] An object of an embodiment of the invention is to propose a seating device for a tilting vehicle in which a seat can be easily and weather-resistantly fixed to the supporting structure of the tilting vehicle.

[0006] This object is achieved by a seating device for a tilting vehicle with a supporting structure, with at least one seat, which comprises a seat surface on which a user can be arranged sitting, which comprises a seat pan on the side opposite the seat surface and which comprises at least one elastically compressible cushioning body between the seat surface and the seat pan, wherein the seat can be releasably fixed by means of the seat pan to the supporting structure of the tilting vehicle in a contact-fitting manner, and with at least one locking device, which comprises a projection means which is fixed to the supporting structure and which projects towards the seat, which has a receiving unit which is fixed to the seat pan,which has a locking means and which, for securing the seat to the support structure along a joining direction, can be plugged onto the projection means and can be secured by the locking means in a locking position of the locking means on the projection means against movement counter to the joining direction, and which comprises a manually operable unlocking means arranged between the seat surface and the seat pan, which includes an actuating section that is at least partially surrounded by the upholstery body, and by means of which the locking means can be transferred from the locking position into a release position released from the projection means by manually actuating the actuating section, in which release position the seat is free to move counter to the joining direction.

[0007] Because the seat device comprises a locking device which has a receiving unit which can be unlocked by an unlocking means arranged between the seat surface and the seat pan, the locking device is arranged in an improved manner to protect it against environmental influences.

[0008] Since the bench seat can be arranged on the support structure by placing it on the projection means and can be fixed by securing it to the projection means, the bench seat can be arranged and fixed on the support structure of the seating device in a simple manner.

[0009] By manually actuating the release mechanism, the receiving unit releases the projection means, allowing the seat to be easily detached and removed from the supporting structure without the need for tools. A tilting vehicle refers to bicycles, motorcycles, or motorcycle-like motor vehicles, such as scooters, in particular two-, three-, or four-wheeled scooters, tilting trikes, quads, or the like.

[0010] Because the unlocking means is arranged between the seat surface and the seat pan and the actuating section of the unlocking means is at least partially surrounded by the upholstery body, the unlocking means runs entirely or at least partially within the seat bench.

[0011] Embodiments of the seat device are conceivable in which the receiving unit is fixed to the seat pan on the side of the seat pan facing the support structure or is fixed to the seat pan on the side of the seat pan facing away from the support structure, wherein the seat pan comprises a continuous recess through which the projection means can be pushed for arrangement in the receiving unit, and / or in which the locking means is fixed to the projection means in a releasable manner in the locking position, in particular in a frictional and / or positively locking manner.

[0012] If the receiving unit is fixed to the seat pan on the side of the seat pan facing the supporting structure, this is easier to access for the projection means.

[0013] If the receiving unit is fixed to the seat pan on the side of the seat pan facing away from the supporting structure, the receiving unit is also protected from environmental influences and is arranged within the seat between the seat pan and the supporting structure.

[0014] If the locking means is releasably attached to the

[0015] If the projection is fixed, this can be done, for example, by frictional engagement. In this case, the seat is clamped to the projection by the receiving unit.

[0016] If the seat pan is fixed by forming a positive connection between the locking means and the fixing means, a rear grip is formed with respect to the joining direction.

[0017] In embodiments of the seat device, it proves to be advantageous if the unlocking means can be transferred from an unactuated basic position into an actuated position by a rotational movement about a rotation axis and / or by a translational movement along an unlocking direction, in which the locking means is arranged in the release position, in particular wherein the unlocking direction of the unlocking means runs transversely or obliquely to the joining direction, and / or if the transfer of the locking means from the release position into the locking position and vice versa comprises a rotational movement about a locking rotation axis or a translational movement transversely or obliquely to the joining direction.

[0018] If the unlocking means can be transferred from the unactuated basic position into the actuated position by a translational movement along an unlocking direction, the unlocking means can be easily pressed by a user.

[0019] It is conceivable that the unlocking means is moved by a translational movement along the unlocking direction, and this movement leads to a rotational movement of the locking means. In this case, the locking means can easily comprise a rotary lock or the like.

[0020] Furthermore, the locking means and unlocking means are movable relative to one another. If the unlocking means can be moved from the basic position to the actuated position by a rotational movement and, at the same time, the locking means can also be moved from the release position to the locking position and vice versa by a rotational movement, the unlocking means and locking means can be fixed to one another in a rotationally fixed manner.

[0021] In principle, bench designs are conceivable in which the seat surface directly adjoins and merges with the seat pan. With a more heavily padded bench, it is advantageous for the bench to include a side panel extending between the seat surface and the seat pan, particularly if the seat surface and side panel comprise a common, one-piece component, in particular a flexibly bendable cover.

[0022] In this case, the upholstered body is completely enclosed by the seat, side panels, and seat pan. If the seat and side panels comprise a single, integral component, this can be, for example, a flexible, bendable covering material. The covering material can be made of textile, leather, or plastic, for example.

[0023] Furthermore, in embodiments of the seat device, it can be provided that the actuating section of the unlocking means is arranged entirely within the seat bench, limited to the outside by the seat surface and / or by the side surface of the seat bench, and can be actuated through the seat surface and / or the side surface of the seat bench, in particular through a region of the upholstery body, or that the actuating section projects outwards through a recess in the seat surface and / or in the side surface of the seat bench and is freely accessible and actuable from the outside.If the actuating portion of the release means is arranged entirely within the seat, enclosed on the outside by the seat surface and / or the side surface of the seat, and can be actuated through the seat surface and / or the side surface of the seat, in particular through a region of the upholstery, the release means is arranged entirely within the seat. This allows the actuating means to be easily felt and actuated by a user of the motor vehicle.

[0024] In order to increase the seating comfort of the seating device, the actuating section of the unlocking means can preferably be actuated by a side surface of the seat.

[0025] If the actuating section projects outwards through a recess in the seat surface and / or in the side surface of the seat bench and is freely accessible and operable from the outside, the actuating section of the unlocking means is easier to grasp and does not have to be felt and found by a user of the motor vehicle.

[0026] The unlocking means can, in principle, be designed in any way, as long as it is suitable for manual grasping and actuation. The unlocking means can be designed compactly if the unlocking means is designed as a rod, pin, or stud and / or includes an actuating surface extending transversely or obliquely to the actuation direction.

[0027] If the release mechanism is designed as a rod, pin, or stud, the volume of the release mechanism is reduced. This makes it possible, for example, to fix the receiving unit centrally with respect to the seat and to bridge the distance from the center of the seat to the side surface with the release mechanism. If the release mechanism comprises an actuating surface extending transversely or diagonally to the actuating direction, the release mechanism can be easily operated with a user's finger and, in particular, can be transferred from the unactuated basic position to the actuated position by means of the rotational movement and / or the translational movement.

[0028] In addition, when forming an actuating surface extending transversely or obliquely to the actuating direction, a possibility can be created with which the unlocking means in the unactuated basic position lies flat against the side surface of the seat bench without it being detectable by the user from the outside, for example by a bulge or the like.

[0029] If the operating surface runs parallel to the side of the seat, damage to the side of the seat can be prevented.

[0030] A movement of the unlocking means onto the locking means can be ensured in a simple manner if the unlocking means comprises a pin extending transversely to the actuation direction on the end opposite the actuation surface and if the locking means comprises a through opening extending transversely to the actuation direction, in which opening the pin is movably arranged, wherein the movement of the unlocking means in the actuation direction can be transferred to the locking means by means of the pin.

[0031] This makes it possible for the unlocking means to be movable relative to the locking means and at the same time allows a movement of the unlocking means towards the locking means.

[0032] For example, if the release means is along the

[0033] If the locking means is movable by translation in the unlocking direction, the locking means can be rotated about a rotation axis through the interaction of the pin and the opening.

[0034] In order to ensure that the receiving unit is automatically fixed to the projection means when arranged on the projection means and / or in order to ensure that the unlocking means is always easily graspable, in particular palpable, it proves to be advantageous if the locking device comprises at least one tensioning means by which the locking means is pretensioned into the blocking position and / or by which the unlocking means is pretensioned into the unactuated basic position.

[0035] In this case, embodiments are conceivable in which only the locking means is directly pre-tensioned into the locking position by the clamping means, wherein the locking means in such a case transfers the unlocking means into the unactuated basic position.

[0036] In order to ensure that the unlocking means can be operated easily and without problems, in one embodiment of the seat device at least one clamp-like or clamp-like guide means is provided which is fixed to the seat pan, which surrounds a guide section of the unlocking means arranged between the actuating surface and the pin and at least limits a movement of the unlocking means transversely to the actuating direction.

[0037] The clamp-like or clip-like guide means can rest on the guide section of the unlocking means in such a way that it touches and surrounds it on the side facing away from the seat pan. In this case, the unlocking means is secured against movement in a direction transverse to the seat pan. Furthermore, the clamp-like or clip-like guide means can be designed such that it surrounds the guide section of the unlocking means at least in sections on the sides running transversely thereto. As a result, the unlocking means is at least limited against movement transverse to the actuation direction when moving along the actuation direction. Limited means that although the unlocking means is surrounded by the clamp-like or clip-like guide means, it is not clamped in a force- or friction-locking manner, but rather a relative movement between the guide means and the unlocking means in the form of a sliding movement in the actuation direction is permitted.

[0038] In addition, several, in particular two, three, or four, clamp-like guide means can be provided, spaced apart from one another. This reduces the risk of jamming during movement.

[0039] In principle, it is conceivable for the projection means of the locking device to be attached to the supporting structure in any desired manner. The projection means can be releasably attached, in particular with a force-fitting and form-fitting connection, or non-releasably attached, in particular with a force-fitting, form-fitting, and / or material-fitting connection.

[0040] It proves to be advantageous if the projection means of the locking device can be releasably fixed on the side of the support structure facing the seat pan and can be detached from the support structure, in particular from the side of the support structure facing away from the seat pan.

[0041] If the projection means of the locking direction can be releasably fixed on the side of the support structure facing the seat shell, the projection means can be easily arranged on existing seating devices and can be retrofitted to existing tilting vehicles.

[0042] If the projection means is detachable from the support structure from the side of the support structure facing away from the seat shell, the seat can be removed from the support structure with the projection means arranged in the receiving unit. This can be particularly advantageous if the receiving unit and / or the release means are damaged. In this case, the seat can be removed from the support structure without the seat being able to be removed, for example, by cutting open the cover means and / or the upholstery body.

[0043] In such a case, the projection means can be fixed to the supporting structure, for example by screwing.

[0044] The projection means may comprise a mushroom-shaped portion arranged on the side facing the seat surface. This allows the locking means, in the locking position, to engage behind the mushroom-shaped portion opposite to the joining direction and create a positive connection.

[0045] Furthermore, the projection means may comprise a section which is recessed transversely to the joining direction and which is engaged behind by the locking means in the locking position to form a rear grip.

[0046] Further features, details and advantages of the invention emerge from the appended patent claims, from the drawings and the following description of a preferred embodiment of the seating device.

[0047] The drawing shows:

[0048] Figure 1 A partially transparent plan view of an embodiment of the seating device according to the invention;

[0049] Figure 2: A detailed view in the area of ​​the locking device as shown in Figure 1; Figure 3: A sectional side view parallel to the longitudinal direction of the tilting vehicle through a projection means.

[0050] The figures show a seating device for a tilting vehicle (not explicitly shown in the figures), designated overall by the reference number 2.

[0051] The seating device 2 comprises a support structure 4 (visible only in Figure 3) and a bench seat 6. The bench seat 6 comprises a seat surface 8 on which a user can be seated. On the side opposite the seat surface 8, the bench seat 6 comprises a seat pan 10. An elastically compressible cushioning body 12 is arranged between the seat surface 8 and the seat pan 10.

[0052] The seat 6 can be secured to the support structure 4 with the seat pan 10 resting against the support structure 4. For this purpose, the seat device 2 comprises a locking device 14, which comprises a projection 16 that is secured to the support structure 4. The projection 16 projects toward the seat 6. In the exemplary embodiment shown in the figures, the projection 16 is releasably secured to the support structure by screwing.

[0053] The projection means 16 comprises a mushroom-shaped section, with which the projection means 16 is arranged in a receiving unit 18 of the locking device 14. The receiving unit 18 is fixed to the seat pan 10 of the seat bench 6. The receiving unit 18 comprises a locking means 20. To secure the seat bench 6 to the support structure 4, the receiving unit is plugged onto the projection means 16 along a joining direction 22. The locking means 20 is thus fixed to the projection means 16, whereby the seat bench 6 is fixed to the support structure 4 against movement counter to the joining direction 22. In the exemplary embodiment shown in the figures, the locking means forms a rear engagement with the mushroom-shaped section of the projection means 16 with respect to the joining direction 22.

[0054] Furthermore, the locking device 14 comprises an unlocking means 24 arranged between the seat surface 8 and the seat pan 10. The unlocking means 24 comprises an actuating portion 26 that is at least partially surrounded by the cushion body 12. The unlocking means 24 allows the locking means 20 to be moved from the locked position into a release position released from the projection means 16 by manually actuating the actuating portion 26. In the release position, the seat bench 6 is released for movement opposite to the joining direction 22.

[0055] In the exemplary embodiment shown in the figures, the receiving unit 18 is fixed on the side of the seat pan 10 facing the seat surface 8. The projection means 16 protrudes through a continuous recess 28 provided in the seat pan 10 to reach the receiving unit 18.

[0056] The unlocking means 24 comprises, on the side facing the locking means 20, a pin 32 extending transversely to an actuating direction 30. This pin 32 is arranged in a through opening 34 in the locking means 20 extending transversely to the actuating direction 30 and allows a relative movement of the pin 32 in the opening 34. This enables the unlocking means 24 to perform a translational movement along the actuating direction 30. The actuating direction 30 runs transversely to the joining direction 22. The movement transmitted by the unlocking means 24 via the pin 32 to the locking means 20 results in a rotational movement of the locking means 20 about a rotational axis. By rotating about the rotational axis, the locking means 20 is transferred from the locking position to the release position and back again.In order to pre-tension the locking means 20 into the locking position, the locking device 14 comprises a tensioning means 36 by which the locking means 20 is pre-tensioned into the locking position.

[0057] In order to guide a movement of the unlocking means 24 along the actuating direction 30, the seat device 2 comprises a clamp-like or clip-like guide means 38 which is fixed to the seat pan 10 and which surrounds a guide section 40 of the unlocking means 24 arranged between the actuating section 26 and the pin 32 and at least limits a movement of the unlocking means 24 transversely to the actuating direction 30.

[0058] In the embodiment shown in the figures, two guide means 38 are provided which are spaced apart from one another.

[0059] In the exemplary embodiment shown in the figures, a side surface 42 is arranged between the seat surface 8 and the seat pan 10. The side surface 42 and the seat surface 8 comprise a common, one-piece component, in particular a common, flexibly bendable cover element.

[0060] The release means 24 and the receiving unit 18 are arranged entirely within the seat 8. As a result, the release means 24 does not extend through the seat surface 8 or the side surface 42. The actuating section 26 of the release means 24 can be actuated by pressing on the side surface 42 and, if appropriate, the cushion body 12 arranged therebetween.

[0061] The features of the invention disclosed in the above description, in the claims and in the drawings can be essential both individually and in any combination in the realization of the invention in its various embodiments within the scope of the following claims.
