Description

Technical Field

[0001] This invention relates to a vehicle swivel seat for vehicles. Background Technology

[0002] Vehicle seats can be rotatable to accommodate various usage scenarios within the vehicle. For example, rotating a seat towards the vehicle door can make entering or leaving the vehicle easier. Furthermore, it might be desirable to rotate a vehicle seat 180 degrees so that the occupant of the rotatable seat can face other occupants in the rear seats of the vehicle, for example, to facilitate more natural conversation between occupants.

[0003] CN 214607191 U describes a rotatable vehicle seat that can be unlocked and manually rotated. However, motor-driven adjustment of the vehicle seat could be more convenient to operate and allow for improved control.

[0004] CN 213973681 U describes a motor-driven rotatable vehicle seat. In this seat, an inner circumferential gear ring is engaged by a pinion that rotates by means of a motor.

[0005] However, it has been found that solutions with driven pinions that roll along the inner circumferential gear ring may tend to have a considerable weight. Summary of the Invention

[0006] One object of the present invention is to provide an improved vehicle swivel seat.

[0007] This objective is achieved by a vehicle swivel seat having the features of claim 1.

[0008] Accordingly, a vehicle swivel seat includes a base, a carrier rotatably supported on the base, a seat portion (directly or indirectly) mounted on the carrier, and a drive unit for driving the carrier (together with the seat portion) to rotate relative to the base. Specifically, the drive unit includes a motor unit and a spindle capable of being driven by the motor unit to displace relative to the motor unit.

[0009] By using a motor unit with a spindle, i.e., a spindle drive, the overall weight of the components can be reduced, especially because a large internal circumferential gear ring is not required. Furthermore, reduced play can be achieved. Thus, a motor-driven swivel seat for vehicles is provided, allowing for reduced weight, convenient use with improved control, and minimal play. Moreover, the construction of this spindle drive can be relatively simple and robust. The spindle has a spindle axis. The threads of the spindle define a helix around the spindle axis. The spindle axis is oriented along the length of the spindle. Actuation of the motor unit causes the spindle to shift relative to the motor unit along its spindle axis.

[0010] The drive unit can be pivotally mounted on the base or on the carrier. This simplifies the transmission of the force generated by the motor unit to drive the rotation of the carrier.

[0011] The motor unit has a motor shaft rotation axis. For example, the electric motor of the motor unit has a stator and a rotor, the rotor being rotatable relative to the stator about the motor shaft rotation axis. The main shaft can extend at an angle relative to the motor shaft rotation axis, particularly perpendicular to the motor shaft rotation axis. This allows for a compact construction.

[0012] The support member is mounted to be rotatable relative to the base about a rotation axis passing through the seat portion. Wherein, when the vehicle swivel seat is oriented for use so that an occupant can sit, the rotation axis is oriented vertically.

[0013] The carrier can rotate at least 180 degrees relative to the base, optionally 360 degrees. This allows for turning of the rear seats.

[0014] The drive unit can be mounted on one of the base and the carrier. The drive unit can be operatively connected to the other of the base and the carrier by means of a rotary drive mechanism. For example, the drive unit can be mounted to the base (or the carrier) in a fixed or rotatable manner, and the rotary drive mechanism connects the drive unit (particularly the spindle) to the carrier (or the base). This allows for a robust connection and efficient drive.

[0015] The rotary drive mechanism may include a linkage. The linkage may be fixed to the spindle. The linkage may be pivotally connected to either the base or the carrier. This allows for a robust and durable mechanism. Backlash can be significantly reduced compared to solutions with an internal circumferential gear ring.

[0016] Alternatively, the rotary drive mechanism may include a lever pivotally connected to the spindle. This allows for a wide range of rotation using a relatively short spindle with minimal backlash.

[0017] For example, the rod is pivotally mounted on the base. A connecting rod can be pivotally connected to the rod. The connecting rod can be pivotally connected to the carrier. Thus, the connecting rod can connect the rod to the carrier. This allows for a further increase in the range of rotation. Furthermore, these components can form a four-bar linkage. This allows for precise adjustment and minimal backlash. More generally, the vehicle swivel seat can include a swivel drive mechanism with a four-bar linkage.

[0018] In one example, the connecting rod is arched. This allows the axis of rotation to be positioned between the connection point of the connecting rod and the member, and between the connection point of the connecting rod and the support member (or the base). Therefore, a wide range of rotation of the support member can be achieved through a simple design.

[0019] The rod can be fixed to the load-bearing member. This allows the design to be simple yet robust and durable.

[0020] Alternatively, the rod can be pivotally mounted to the load-bearing member. This allows for a wide range of rotation.

[0021] In one example, the rod is arched. This allows for a greater degree of rotation, and the drive unit can be arranged more flexibly.

[0022] The rotary drive mechanism may include a pinion. The pinion may be fixed to one of the base and the carrier. The rotary drive mechanism may include a toothed segment. The toothed segment may be pivotally mounted on the other of the base and the carrier. The toothed segment may mesh with the pinion. The toothed segment may be pivotally connected to the spindle. This allows for a simple and compact design.

[0023] The rotary drive mechanism includes a traction element. The traction element can form a closed loop. The main shaft can be fixed to a section of the traction element, for example, by means of a connector. This allows for large rotation angles and simple installation of the drive unit.

[0024] For example, the traction element is a belt or chain. These are robust and durable components and standard parts.

[0025] The base may include a base plate. The base may include, for example, a circular bearing mounted on the base plate. Such a base plate can provide uniform support. The circular bearing can provide robust and durable support for the load-bearing component with the seat portion.

[0026] The base may include one or more hooks. The support member may include one or more hooks. At least one hook of the base may engage with at least one hook of the support member, at least in one rotational position of the support member relative to the base. Such engaged hooks can provide robust support even under abnormal loads, such as in an accident.

[0027] For example, at least one hook of the support member is movably resting on the circular bearing. In this way, the hook can have a dual function: support during use and safety against abnormal loads.

[0028] In some examples, the base is mounted on a longitudinal adjustment mechanism. This longitudinal adjustment mechanism allows for displacement along an axis at an angle (e.g., perpendicular to the axis of rotation of the carrier). Such a longitudinal adjustment mechanism, combined with the swivel seat, allows for comfortable adjustment of the vehicle seat.

[0029] The seat portion can be mounted on the support member via a height adjustment mechanism. Therefore, it is not necessary to use the height adjustment mechanism to lift the weight of the support member and the base. This increased freedom of adjustment in the vehicle swivel seat allows for further enhancement of comfort.

[0030] The backrest can be pivotally mounted on the seat portion. This allows the seat portion and the backrest to be adjusted as a single unit.

[0031] According to one aspect, a vehicle is provided that includes a vehicle swivel seat according to any aspect or embodiment described herein. Regarding the advantages of this vehicle swivel seat, please refer to the description above. Attached Figure Description

Detailed Implementation

[0033] Figure 1 A vehicle seat for a vehicle, in the form of a vehicle swivel seat 1, is shown. Vehicle seat 1 can be a front passenger seat, a driver's seat (particularly in autonomous vehicles), or a seat in the second row or other rows of seats in a vehicle. The vehicle swivel seat, hereinafter simply referred to as vehicle seat 1, includes a seat portion 12 and a backrest 15. A person can sit on the seat portion 12 and rest their back against the backrest 15. Figure 1 The structural components of the seat portion 12 and the backrest 15 are shown in the diagram. In use, a cushion or similar material is installed on the seat portion 12 and the backrest 15.

[0034] A backrest 15 is mounted on a seat portion 12. The backrest 15 is pivotable relative to the seat portion 12. For this purpose, the backrest 15 is connected to the seat portion 12 via an adjuster device, which in this example includes two adjusters 18 operable to pivot the backrest relative to the seat portion 12 about a pivot axis B. The backrest further includes an opening (at the upper edge) for guiding the seat belt through. In the installed state, the seat belt is mounted on the backrest 15.

[0035] The vehicle seat 1 further includes a longitudinal adjustment mechanism 16. The longitudinal adjustment mechanism 16 allows the seat portion 12, together with the backrest 15, to be displaced along the longitudinal axis X. When installed in a vehicle, the longitudinal axis X corresponds to the vehicle's longitudinal axis in the vehicle coordinate system. The longitudinal adjustment mechanism 16 includes two pairs of guide rails. Each pair of guide rails is arranged parallel to each other and parallel to the longitudinal axis X. Each pair of guide rails is displaced relative to each other along the transverse axis Y. The transverse axis Y is perpendicular to the longitudinal axis X. The longitudinal axis and the transverse axis open into a plane (XY plane), which is horizontal when installed in a vehicle arranged on a horizontal surface. The vertical axis Z is perpendicular to the longitudinal axis X and perpendicular to the transverse axis Y. When the vehicle seat 1 is installed in a vehicle arranged on a horizontal surface, the vertical axis Z is vertical.

[0036] The vehicle seat 1 further includes a swivel mechanism 19, which will be described in more detail below. The swivel mechanism 19 allows the seat portion 12 (together with the backrest 15) to rotate about a swivel axis A, up to 180 degrees in this example. The swivel axis A is parallel to the vertical axis Z. Therefore, it is perpendicular to the XY plane. The swivel axis A is oriented upright when the vehicle seat 1 is oriented to be usable for occupants to sit on. In use, a person sitting (or seated) in the vehicle seat 1 can use the swivel mechanism 19 to rotate the seat portion 12 and the backrest 15, for example, by 90 degrees for easier exiting (or entering), or by 180 degrees to face occupants in the second or third row of seats in the vehicle. The swivel axis A is perpendicular to the backrest pivot axis B. The swivel axis A passes centrally through the seat portion 12. Figure 1 In the example, the slewing mechanism 19 is mounted on the longitudinal adjustment mechanism 16.

[0037] In addition, the vehicle seat 1 includes a height adjustment mechanism 17. The height adjustment mechanism 17 is used to adjust the height of the seat portion 12 (together with the backrest 15) along the vertical axis Z. The height adjustment mechanism 17 includes two pivotable links on the left and right sides. These links can be rotated to raise or lower the seat portion 12.

[0038] It is worth noting that the height adjustment mechanism 17, the longitudinal adjustment mechanism 16, and the angle adjuster device 18 are not necessarily provided. Figure 1 The vehicle seat 1 may include all these adjustment mechanisms, but may also include only one or two of these mechanisms, or even none of them.

[0039] Here, the slewing mechanism 19 is mounted on the longitudinal adjustment mechanism 16. The height adjustment mechanism 17 is mounted on the longitudinal adjustment mechanism 16. The seat portion 12 is mounted on the height adjustment mechanism 17. Therefore, the longitudinal adjustment mechanism 16 is configured to carry the slewing mechanism 19, the height adjustment mechanism 17, the seat portion 12, and the backrest 15. The slewing mechanism 19 is configured to carry the height adjustment mechanism 17, the seat portion 12, and the backrest 15.

[0040] Figure 2 The slewing mechanism 19 is shown separately. The slewing mechanism 19 (and therefore the vehicle seat 1) includes a base 10A and a carrier 11A rotatably supported on the base 10A. Figure 1 In the shown installation configuration, the base 10A is mounted on the longitudinal adjustment mechanism 16, and the height adjustment mechanism 17 is mounted on the support member 11A. The seat portion 12 is mounted on the support members 11A and 11B. More specifically, the seat portion 12 is mounted on the support members 11A and 11B by means of the height adjustment mechanism 17. The base 10A includes a base plate 100A, the main portion of which is planar. It has edges extending around its outer edge. The base plate 100A has a square outer shape with rounded corners. The support member 11A is also mainly planar and has a square outer shape with rounded corners. The outer shapes of the base 10A and the support member 11A match each other. This configuration allows for a very flat structure.

[0041] The carrier 11A is mounted to be rotatable about the axis of rotation A relative to the base 10A. At its center, a mating bolt (or other fastener) rotatably secures the carrier 11A to the base 10A. The mating bolt 111 is located in a central recess of the carrier 11A. The mating bolt 111 extends through a central hole 112A in the carrier 11A. The carrier 11A is capable of rotating 180 degrees relative to the base 10A.

[0042] exist Figure 2 In the image, you can also see the components of bearing 101A and drive unit 13, which will now be described in more detail.

[0043] Turning Figure 3A and 3B The image shows a view of the base 10A without the support member 11A, so that the bearing 101A and the drive unit 13 can be fully seen from the top.

[0044] Bearing 101A is circular. Bearing 101A is mounted on base plate 100A. Bearing 101A extends adjacent to the outer edge of base plate 100A. As an example, bearing 101A is made of plastic. As an example, base 10A and carrier 11A are made of metal (e.g., steel). Multiple rollers 103 are mounted in bearing 101A. Each roller 103 has the shape of a roll, but alternatively, it can be formed as a ball. The rollers 103 are arranged in a receiving portion in bearing 101A, arranged around axis of rotation A, and on the side facing carrier 11A. In this example, bearing 101A is made of multiple parts. That is, bearing 101A includes four segments 107 (while other numbers are also conceivable). Figure 9 The diagram shows one segment of segment 107. Segment 107 defines one-quarter of a circle. Segment 107 has an opening in which the roller 103 is arranged. Segment 107 has a male connector 108 end and a female connector 109 end. Thus, segments 107 can be securely connected to each other to form bearing 101A.

[0045] The rotary mechanism 19 further includes a drive unit 13 for driving the carrier 11A to rotate relative to the base 10A. The drive unit 13 includes a motor unit 130 and a spindle 131 capable of being driven by the motor unit 130 and displaced relative to it. The drive unit 13 is mounted on the base 10A. More specifically, the drive unit 13 (including the motor unit 130) is pivotally mounted on the base 10A. It is noteworthy that, alternatively, the drive unit 13 may be mounted on the carrier 11A.

[0046] Drive unit 13 in Figure 6 The diagram is shown in more detail below. Motor unit 130 includes an electric motor and a gearbox. Motor unit 130 has a spindle nut. Actuation of motor unit 130 causes spindle nut to rotate in a selectable direction of rotation. Spindle nut is rotatably held on motor unit 130. Drive unit 13 further includes a bracket 134 on which motor unit 130 is mounted. Bracket 134 includes an opening, such as... Figure 3A and 3B In the shown installation configuration, a bolt or similar object extends through the opening. This connection holds the drive unit 13 to the base 10A but allows the drive unit 13 to pivot relative to the base 10A. The mounting bracket 132, fixed to the base 10A, allows for pivotable connection to a second hole on the bracket 134 (on the other side of the spindle 131) for a more secure connection. Thus, the drive unit 13 is able to pivot relative to the base 10A about the pivot axis P (see [reference]). Figure 6 ).

[0047] Motor unit 130 has a motor shaft rotation axis R. The rotor of motor unit 130 is supported so as to be rotatable relative to the stator of motor unit 130 about the motor shaft rotation axis R. Motor unit 130 has a motor shaft fixed to the rotor. Main shaft 131 extends perpendicular to the motor shaft rotation axis R. More specifically, main shaft 131 is elongated, and its elongated axis is perpendicular to the motor shaft rotation axis R.

[0048] The spindle 131 includes an external thread. The spindle 131 is threadedly engaged with a spindle nut. Thus, rotation of the spindle nut causes the spindle to screw in or out depending on the direction of rotation. Rotation of the spindle 131 is prevented by connecting the spindle to the rotary drive mechanism 14A. The drive unit 13 is mounted on the base 10A and is operatively connected to the carrier 11A by means of the rotary drive mechanism 14A.

[0049] The main shaft 131 is pivotally connected to a link 140A of the rotary drive mechanism 14A. The main shaft 131 and the link 140A together form a pivot shaft P. In this example, a connecting ring 133 is formed at one end of the main shaft 131. The connecting ring 133 is pivotally connected to the link 140A of the rotary drive mechanism 14A, for example, by means of a bolt or the like. The bolt extends through a hole in the connecting ring 133 and the link 140A. The hole in the link 140A is located at one end of the link 140A.

[0050] The rod 140A itself is pivotally mounted on the base 10A. For this purpose, the rod 140A includes a hole between its two ends, through which the rod 140A is pivotally mounted on the base 10A about an additional pivot axis P.

[0051] Link 140A has a third pivot P, which in this example is located at the other end of its connection to the connecting link 141 of the rotary drive mechanism 14A. Similarly, link 140A has a hole for a bolt or similar for this pivot P. The three pivots P of link 140A are arranged in a straight line. Corresponding holes in link 140A are also arranged in a straight line. Furthermore, the central pivot P is positioned closer to the pivot P connected to the main shaft than the pivot P near the connecting link 141. This provides a leverage effect, allowing the connecting link 141 to move more than the corresponding movement of the main shaft 131.

[0052] The connecting rod 141 is pivotally connected to the carrier 11A. Here, the connecting rod 141 is, for example, by means of... Figure 2The bolt 147 shown is pivotally connected to the carrier 11A. The bolt 147 extends through a hole 112B in the carrier 11A. The bolt 147 (and the connection point) is eccentric relative to the mating bolt 111 and the axis of rotation A. Therefore, movement of the connecting rod 141 causes rotation of the carrier 11A relative to the base 10A. The connecting rod 141 connects the rod 140A to the carrier 11A.

[0053] The rotary mechanism 19 includes a four-bar linkage. More specifically, the base 10A, link 140A, connecting link 141, and spindle 131 (together with its connection to the base 10A) together form the four-bar linkage. The length of one of the links (i.e., the spindle 131) is adjustable to adjust the position of the four-bar linkage. The four-bar linkage allows for high adjustment speed, continuous stepless adjustment, minimal free play, and light weight.

[0054] The connecting rod 141 is arched. More specifically, the connecting rod 141 has a circular cross-section. As a result, the connecting rod 141 allows the load-bearing member to rotate around a large angle because, due to its shape, it will not interfere with the mating bolt 111.

[0055] For example, this can be done Figure 3A and 3B I saw it in [the text]. Figure 3A The starting position is shown in the image, for example... Figure 1 The seat portion 12 is positioned in the forward travel direction. The main shaft 131 is fully retracted, and the motor side of the lever 140A is pulled toward the motor unit 130. The connecting rod 141 is pulled toward the side of the drive unit 13. When the motor unit 130 is activated, the main shaft 131 extends, causing the connecting ring 133 to move away from the motor unit 130. The lever 140A pivots about its pivot axis P connected to the base 10A, thereby pushing the connecting rod 141. As a result, the connecting rod 141 pushes the carrier 11A to rotate about the axis of rotation A relative to the base 10A. During this movement, the drive unit 13 pivots relative to the base 10A.

[0056] It is worth noting that the motor unit 130 is arranged within a cutout 104 in the base plate 100A. This cutout 104 allows for the pivoting movement of the motor drive 130 while accommodating most of the components of the motor unit 130 below the base 10A, such as... Figure 4 As shown, the rod 140A and the connecting ring 141 (as well as the main shaft 131) are arranged between the base 10A and the bearing member 11A. This allows for a particularly flat structure.

[0057] The drive unit 13 and the rotary drive mechanism 14A are arranged within a circle defined by the bearing 101A.

[0058] Further reference Figure 5 and 8 ,from Figure 4 It can also be specifically seen that hook 102 is fixed (e.g., welded) to base 10A, and hook 110 is fixed (e.g., welded) to carrier 11A. At least in some rotational positions of carrier 11A, hook 110 of carrier 11A engages with hook 102 of base 10A. Here, hooks 102 and 110 engage in the initial position, after rotating 90 degrees relative to the initial position, and after rotating 180 degrees. Hooks 102 and 110 are arranged at the four corners of base 10A and carrier 11A. Figure 3A , 3B As shown in Figures 5 and 7, four pairs of hooks 102 and 110 are provided (equally spaced around the axis of rotation A).

[0059] Hooks 102 and 110 provide secure retention of the load-bearing member 11A on the base 10A even under impact loads.

[0060] Hooks 102 and 110 extend along a section of the circular bearing 101A. Hook 110 of the carrier 11A rests movably on the circular bearing 101A. Hook 110 of the carrier 11A rolls on rollers 103 on the bearing 101A. The bearing 101A forms a cage for the rollers 103.

[0061] Furthermore, the hook 102 of the base 10A has an overmolded layer (e.g., made of plastic) that reduces friction and clearance between the hook 102 of the base 10A and the corresponding hook 110 of the carrier 11. In cross-section, the hooks 102 and 110 have a J-shape.

[0062] Figure 4 and 5 A nut 106 is also shown formed on or fixed to the base plate 100A. A mating bolt 111 is screwed into the nut 106. In this example, the mating bolt 111 is a shoulder bolt.

[0063] Turn now Figure 10A , 10B 10A and 11, the alternative rotary drive mechanism 14B will now be described. Although the base 10A, the carrier 11A and the drive unit 13 may be simply as described above, the rotary drive mechanism 14A includes a toothed segment 143 and a pinion 142 in place of the rod 140A and the connecting rod 141.

[0064] The pinion 142 is fixed to the carrier 11A. The toothed section 143 is pivotally mounted on the base 10A via a pivot shaft P. The toothed section 143 is in gear mesh with the pinion 142. The toothed section 143 is pivotally connected to the main shaft 131 via another pivot shaft P.

[0065] When the drive unit 13 is as described above (especially referenced) Figure 3A and 3B During operation, the spindle 131 is pulled against (or pulled according to the direction of movement) the toothed segment 143 at another pivot axis P. This other pivot axis P is offset from the pivot axis P, thus causing the toothed segment 143 to pivot relative to the base 10A. Simultaneously with pivoting, the toothed segment 143 rolls along the pinion 142, thereby driving the pinion 142 to rotate. Since the pinion 142 is fixed to the carrier 11A, the carrier 11A is rotated relative to the base 10A.

[0066] from Figure 10A Starting from the position where the central spindle 131 retracts, as... Figure 10B As shown, with the spindle 131 fully extended, the carrier 11A can rotate up to 180 degrees.

[0067] refer to Figures 12 to 14 A further alternative rotary drive mechanism 14C for vehicle seat 1 will now be described.

[0068] As described above, a base 10B, a carrier 11B rotatably supported on the base 10B for supporting the seat portion 12 (e.g., by means of a height adjustment mechanism 17), and a drive unit 13 for driving the carrier 11B to rotate relative to the base 10B are provided. Similarly, the drive unit 13 includes a motor unit 130 and a spindle 131 that can be driven by the motor unit 130 and displaced relative to the motor unit 130.

[0069] The drive unit 13 is part of a rotary drive mechanism 14C, which includes a rod 140B fixed to the main shaft 131. Furthermore, the rod 140B is (directly) pivotally connected to the carrier 11B. This allows for a particularly robust and simple construction. The drive unit can be positioned behind, in front of, or beside the bearing 101B.

[0070] Here, the support member 11B is rotatably fixed to the base 10B by means of a central bearing 101B. The central bearing 101B has an inner through-hole through which cables, etc., can be laid. Offset relative to the central axis of rotation A defined by the centrally located bearing 101B, the rod 140B is pivotally mounted on the support member 11B via a pivot shaft P. Figure 14 As can be seen in the cross-sectional view, member 140B extends between base 10B and bearing member 11B, and is rotatably fixed to bearing member 11B by means of bolts. Member 140B extends coaxially with spindle 131. Member 140B is mounted on one of the longitudinal ends of spindle 131 (or formed as a single piece with one of the longitudinal ends of spindle 131).

[0071] Motor unit 130 is mounted on motor plate 136. Motor plate 136 is mounted on base 10B in a pivotable manner about pivot axis P using bolts.

[0072] The carrier 11B is further supported on the base 10B by means of support members 114 that are further offset from the axis of rotation A than the central bearing 101B. Each support member 114 includes rollers (in this case, balls) configured to roll on the base plate 100B of the base 10B. Depending on the connection position between the rod 140B and the carrier 11B, rotation angles greater than 180 degrees are possible.

[0073] Figure 15 Another rotary drive mechanism 14D for vehicle seat 1 is schematically shown. Refer to the description above to avoid repetition. The rotary drive mechanism 14D includes a rod 140C fixedly connected to the carrier 11B. The rod 140C is pivotally connected to the main shaft 131 via a pivot bearing 135, which forms a pivot axis P (parallel to the rotation axis A).

[0074] Drive unit 13 is mounted to base 10B (not in) via pivot bearing 135 forming pivot shaft P (which is parallel to the axis of rotation A). Figure 15 (As shown in the image).

[0075] This arrangement is particularly robust and durable.

[0076] Figure 16 Another rotary drive mechanism 14E for vehicle seat 1 is schematically shown. Again, to avoid repetition, please refer to the description above.

[0077] Figure 16 The rotary drive mechanism 14E includes a traction element 144. The traction element 144 forms a closed loop. A main shaft 130 is operatively connected to the traction element. In this example, the main shaft 131 is fixed to a section of the traction element 144 by means of a connector 145. The connector 145 is fixed to a section of the traction element 144. The connector 145 is connected to the main shaft 131 either in a fixed manner or via a pivot bearing. The drive unit 13 is fixedly mounted on the base 10B (however, a pivot connection is also possible).

[0078] The traction element 144 is, for example, a belt or chain.

[0079] The traction element 144 is guided around one or more (two in this case) pulleys 146. A connector 145 is connected to the traction element 144 between two pulleys 146. The traction element 149 partially contacts the carrier 11B forming a contact area 149. The contact area 149 may include teeth that mesh with the teeth or links of the traction element 144 or the like. The contact area 149 is circular (or at least forms a portion of a circle).

[0080] Depending on the diameter of the contact area 149 and the distance between the pulleys, the maximum rotation angle of the carrier 11B can be adjusted, with angles of 360 degrees or even greater being possible.

[0081] A tensioner 148 may be provided, which applies a force F to the traction element 144, particularly from the outside of it.

[0082] Figure 17 Another rotary drive mechanism 14F for vehicle seat 1 is schematically shown. Again, to avoid repetition, please refer to the description above.

[0083] Figure 17 The rotary drive mechanism 14F includes a link 140D, which is pivotally connected to the carrier 11B via a pivot bearing 135 (directly) forming a pivot axis (parallel to the rotation axis A). The link 140D is also pivotally connected to the main shaft 131 via a pivot bearing 135 (directly) forming a pivot axis P (parallel to the rotation axis A). The link 140D is elongated and has a straight shape (a curved form is also possible).

[0084] The drive unit 13 is fixedly mounted on the base 10B (but a pivoting connection is also possible). The spindle 131 is arranged, for example, parallel to the longitudinal axis X or the transverse axis Y.

[0085] Figure 18 Another rotary drive mechanism 14G for vehicle seat 1 is schematically shown. Again, to avoid repetition, please refer to the description above.

[0086] Figure 18 The rotary drive mechanism 14G includes a link 140E, which is pivotally connected to the carrier 11B via a pivot bearing 135 (directly) forming a pivot axis P (which is parallel to the rotation axis A). The link 140E is also pivotally connected to the main shaft 131 via the pivot bearing 135 (directly) forming the pivot axis P (which is parallel to the rotation axis A).

[0087] The drive unit 13 is fixedly mounted on the base 10B (but a pivoting connection is also possible). The main shaft 131 is arranged at an angle to the longitudinal axis X and at an angle to the transverse axis Y (and at an angle to the vertical axis Z, particularly perpendicular to the vertical axis Z). According to... Figure 18 Member 140E is arched. It follows a curve. Member 140E is able to grasp around the axis of rotation A.

[0088] Alternatively or additionally, the rotary drive mechanism may include a crank-gear transmission mechanism. The spindle drive is a linear drive mechanism.
