Description

BACKGROUND(a) Technical area

[0001] The present disclosure / invention relates to a long sliding rail system (e.g. a long sliding rail system, e.g. a long sliding rail system or long sliding rail system) for a vehicle seat, and in particular a long sliding rail system for a vehicle seat which can ensure quality and reduce costs through a structural improvement. (b) State of the art

[0002] In general, a vehicle seat comprises a backrest and a seat cushion and is mounted on a seat sliding device (e.g., a seat sliding device) configured to allow the seat cushion to be moved forward and backward (e.g., longitudinally) along the vehicle body.

[0003] Normally, a front seat is mounted on a sliding mechanism with a short longitudinal extension, configured to allow a limited range of forward and backward movement. Conversely, recreational vehicles (RVs) and vans, which have a larger body and floor area than passenger cars, use a sliding mechanism with a long longitudinal extension to increase the adjustment range for forward and backward seat movement. This ensures sufficient legroom for a passenger and creates a comfortable interior.

[0004] The seat-shifting devices described above can be divided into manually operated seat-shifting devices and electrically operated seat-shifting devices, depending on the type of actuation, with electrically operated seat-shifting devices being widely used to increase user comfort.

[0005] In a structural configuration of the electrically operated seat shifting device, an upper rail fixed to a vehicle seat is movable along a lower rail fixed to the vehicle floor by means of a drive electric motor, a gearbox (a reduction gearbox) and a leadscrew, making the vehicle seat movable forwards and backwards.

[0006] Taking into account recent demands for improved user comfort, the electrification of vehicles has increased dramatically, and various comfort features for driver and passenger seats have been significantly expanded to improve driving comfort and convenience.

[0007] In particular, highly complex technologies are applied to the driver's and front passenger's seats to offer the user various amenities. Examples of these technologies include a sliding function that allows the seat to be moved forward and backward, a seat height adjustment function that ensures the user's forward view, a ventilation and heating function for comfortable driving, a tilt function to adjust the angle of the backrest, and various comfort features such as a heating / cooling control switch and a monitor mounted on the back of the seat for a rear passenger.

[0008] Among the techniques mentioned above, the sliding function for implementing a forward and backward sliding movement of a seat can be achieved by transmitting force and direction-of-movement signals to the vehicle electronics. In this case, as described above, various problems can arise because the sliding device is installed in the form of a long sliding mechanism.

[0009] For example, if a vehicle is equipped with a long sliding mechanism, when a passenger in the third row needs to get in or out, the second-row seat must first be moved forward before the passenger can enter or exit. Since an electric seat cannot be moved forward and / or backward as quickly as the passenger desires, the passenger may be dissatisfied with the forward and / or backward movement of the electric seat.

[0010] To solve the problems described above, a long sliding rail system is provided, configured to operate electrically in normal mode and to be selectively operated manually when a passenger is boarding or alighting in the third row seat.

[0011] The information disclosed above in this "Background" section is provided solely for a better understanding of the background of the disclosure / invention and may therefore contain information that is not part of the prior art already known to a person skilled in the art in this country.

[0039] A preferred embodiment according to the present disclosure / invention is described in detail below with reference to the accompanying drawings.

[0040] The advantages and features of the present disclosure / invention and methods for its implementation will become clearer with reference to the embodiments described in detail below and the accompanying drawings.

[0041] The present disclosure / invention is not limited to the embodiments disclosed below and can be implemented in various forms. These embodiments serve to complete the present disclosure / invention and to fully communicate the scope of the disclosure / invention to those skilled in the art to whom it relates. The present disclosure / invention is defined solely by the scope of its claims.

[0042] In describing the embodiments disclosed herein, a detailed description of publicly known techniques to which the disclosure / invention relates is omitted if it is determined that such a detailed description could obscure the core of the present disclosure / invention.

[0043] The Fig. 1 and Fig. Figure 2 shows views, each depicting the change from an electric mode to a manual mode in a long sliding rail system for a vehicle seat according to an embodiment of the present disclosure / invention, and the Fig. 3 and Fig. Figure 4 shows views that each depict the rotation of a backrest in the long sliding rail system for a vehicle seat according to the embodiment of the present disclosure / invention.

[0044] Additionally, the Fig. 5 and Fig. 6. each actuation of an actuating lever in the long sliding rail system for a vehicle seat according to the embodiment of the present disclosure / invention, and the Fig. 7 and Fig. Figure 8 shows the actuation of a first drive guide and a second drive guide in the long sliding rail system for a vehicle seat according to the embodiment of the present disclosure / invention.

[0045] Furthermore, the Fig. 9, Fig. 10, Fig. 11 to Fig. 12 each the actuation of a third drive guide in the long sliding rail system for a vehicle seat according to the embodiment of the present disclosure / invention, and the Fig. 13, Fig. 14, Fig. 15 to Fig. Figures 16 each show the actuation of a drive module in the long sliding rail system for a vehicle seat according to the embodiment of the present disclosure / invention.

[0046] Furthermore, the Fig. 17 and Fig. 18 each a switching guide in the long sliding rail system for a vehicle seat according to the present embodiment, and the Fig. 19, Fig. 20, Fig. 21 to Fig. Figures 22 show the actuation of the switching guide in the long sliding rail system for a vehicle seat according to the present embodiment.

[0047] As in Fig. As shown in Figure 1, the long sliding rail system for a vehicle seat according to the present embodiment has a lower rail 100 and an upper rail 200.

[0048] The lower rail 100 extends longitudinally along a vehicle floor plate and is firmly attached to it, as shown in the Fig. 13 and Fig. As shown in Figure 15, a rack 102 is provided on the inside of the lower rail 100.

[0049] Furthermore, the upper rail 200 is coupled to the lower rail 100 and attached to a seat cushion 10. The upper rail 200 is also designed so that the seat cushion 10 can slide along the lower rail 100.

[0050] In other words, the long sliding rail system for a vehicle seat according to the present embodiment has a gear module 300, and the gear module 300 has a pinion 302 which engages with the rack 102 (see Fig. 13 and Fig. 14) By such a structural configuration, the upper rail 200, which has the gear module 300, can be moved in the forward and reverse direction of the lower rail 100 when the pinion 302, connected to a drive motor (not shown), is rotated in the forward and reverse direction.

[0051] Here, the upper rail 200 can be moved according to either an electric or a manual mode, and the lower rail 100, which is a long sliding rail, is mounted on the floor panel. For example, when a passenger in the third row needs to enter or exit the vehicle, the second-row seat must be moved forward. In this case, the upper rail 200, when switched between electric and manual modes, can be moved forward and backward along the lower rail 100, allowing the third-row passenger to quickly enter or exit the vehicle.

[0052] For this purpose, the long sliding rail system for a vehicle seat according to the present embodiment can have a drive module 400 and a guide module 500.

[0053] As in the Fig. 13, Fig. 14, Fig. 15 to Fig. As shown in Figure 16, the drive module 400 is vertically movable, coupled to the gear module 300, and configured so that a clutch 304 selectively presses the pinion 302.

[0054] That is, when the clutch 304 provided in the transmission module 300 is selectively moved to press the pinion 302 (see Fig. 16), the drive module 400 can switch / change from electric mode to manual mode.

[0055] Here, the drive module 400 has a main body 410, a pin element 420 and a guide slot 430.

[0056] The main body 410 is attached to a fastening device 200a which is connected to the upper rail 200 so that it can be moved up and down.

[0057] Furthermore, the pin element 420 is coupled to the main body 410 and projects from an upper section of the fastening device 200a. In this state, when the guide module 400 is actuated, the pin element 420 moves the main body 410 from a first position downwards to a second position.

[0058] Here, the first position can be set to a position of the main body 410 corresponding to the electric mode, i.e., a starting position in which the clutch 304 does not press (e.g., on) the pinion 302, and the second position can be set to a position of the main body 410 corresponding to the manual mode, i.e., a position in which the clutch 304 presses (e.g., on) the pinion 302.

[0059] In addition, the guide slots 430 are formed on both sides of the main body 410, and a fastening pin 306a of an input device 306, which faces the coupling 304, is designed so that it is locked / secured in the guide slots 430.

[0060] These guide slots 430 are designed to extend in both upward and downward directions. When the main body 410 is moved downward from the first position to the second position, the retaining pin 306a is moved from the lower position to the upper position. Accordingly, the input device 306 can be moved to cause the clutch 304 to engage the pinion 302 (see Fig. 14 and Fig. 16).

[0061] Preferably, when the main body 410 is moved downwards into the second position, such that the fastening pin 306a is located at the upper section of each of the guide slots 430, the input device 306 is guided and moved through the guide slots 430 in a direction in which the input device 306 presses against the coupling 304. When the main body 410 is moved upwards into the initial position, i.e., the first position, so that the fastening pin 306a is located at the lower section of each guide slot 430, the input device 306 is guided and moved through the guide slots 430 in a direction in which the input device 306 relieves the pressure exerted on the coupling 304. In this case, an elastic restoring force is generated in the direction in which the input device 306 relieves the pressure exerted on the coupling 304.

[0062] Preferably, the guide slot 430 is shaped to have an “S” shape (see Fig. 14 and Fig. 16) According to this shape, when the main body 410 is moved downwards, the fastening pin 306a is pressed to move the input device 306 in a direction in which the clutch 304 is pressed, and when the main body 410 is moved upwards to the starting position, the fastening pin 306a is pulled to move the input device 306 in a direction in which the pressure exerted on the clutch 304 is released.

[0063] The drive module 400 can further comprise an elastic element 440, as shown in the Fig. 13 and Fig. Figure 15 shows that the elastic element 440 can be arranged between a locking jaw (e.g., locking ring shoulder) 422 formed on the pin element 420 and the fastening device 200a. When the drive module 400 switches from electric mode to manual mode, the elastic element 440 can exert an elastic restoring force on the main body 410, which has been moved downwards into the second position. When the drive module 400 switches from manual mode to electric mode, the electrical element 440 can exert an elastic restoring force on the main body 410 so that the main body 410 can be easily moved back into the first position.

[0064] Meanwhile, the guide module 500 transmits a drive force to the drive module 400 to cause the drive module 400 to move from the first position, corresponding to the electric mode, to the second position, corresponding to the manual mode, as shown in the Fig. 11 and Fig. 12 shown.

[0065] The guide module 500 comprises: a first drive guide 510, a second drive guide 520 and a third drive guide 530, each configured to transfer drive force to the drive module 400 to move the main body 410 downwards into the second position by pressing the pin element 420.

[0066] As in the Fig. 7 and Fig. As shown in Figure 8, the first drive guide 510 is designed such that it rotates axially in conjunction with the rotation of a backrest 12 connected to the seat cushion 10, and a locking element (e.g. rotary locking element) 512 is arranged such that it projects along the outer circumferential surface of the first drive guide 510.

[0067] The second drive guide 520 has a projection (or protruding piece) 522 provided along its outer circumferential surface. Due to this structural configuration, when the first drive guide 510 is rotated, the projection 522 is selectively engaged / captured by the rotary locking element 512, and the second drive guide 520 is designed to rotate in a direction opposite to the direction of rotation of the first drive guide 510.

[0068] The third drive guide 530 is designed to selectively press the pin element 420 by being rotated by a first rope C1, which is movable in a direction in which the first rope C1 is pulled in conjunction with the rotation of the second drive guide 520, as shown in the Fig. 9 and Fig. 10 shown.

[0069] For this purpose, the third drive guide 530 has a first bracket 532 and a second bracket 534.

[0070] The first support 532 is connected to the first rope C1 and is designed such that it can be selectively rotated about a reference axis A1 in conjunction with the movement of the first rope C1, which is pulled in the direction in which the first rope C1 is pulled (see Fig. 11).

[0071] The second bracket 534 is arranged so that it overlaps the first bracket 532 and is designed so that it is rotated about a reference axis A2 in conjunction with the rotation of the first bracket 532, i.e., it is rotated in a direction opposite to the direction of rotation of the first bracket 532 (see Fig. 11).

[0072] One side of the second bracket 534 is arranged so that it overlaps the first bracket 532, and the other side is arranged so that it faces the pin element 420.

[0073] Therefore, when the second bracket 534 is rotated by the first bracket 532, one side of the second bracket 534 is rotated in the opposite direction to the rotation direction of the first bracket 532. In this case, the other side of the second bracket 534 presses, as shown in Fig. As shown in Figure 12, the pin element 420 is moved downwards into the second position, allowing the coupling 304 to press against the pinion 302. Accordingly, the operating mode of the upper rail 200 can be switched from electric to manual mode by the first drive guide 510 to the third drive guide 530, which are actuated sequentially as described above.

[0074] Furthermore, the third drive guide 530 can also have a third support 536. As in the Fig. 9 and Fig. As shown in Figure 10, the third bracket 536 is designed to extend from and be integrated with the first bracket 532. Accordingly, the third bracket 536 is rotated in conjunction with the rotation of the first bracket 532 to selectively move a locking module 600 into an unlocked position.

[0075] The locking module 600 is attached to the upper rail 200 and serves to limit the forward and backward movement of the upper rail 200. When pressed by the third bracket 536, the locking module 600 is rotated and selectively released from a locking hole H provided in the lower rail 100. Accordingly, as described above, when the pin element 420 is pressed to switch the operating mode from electric to manual, the upper rail 200 is also switched to a movable state.

[0076] The guide module 500 also has an actuating lever 540, which is connected to the first drive guide 510 via a second cable C2 and is designed to rotate the backrest 12 by moving the second cable C2 in a direction in which the second cable C2 is pulled, as shown in the Fig. 3 and Fig. 4 shown.

[0077] Here, as in Fig. As shown in Figure 1, the actuating lever 540 is actuated in a state in which the backrest 12 is in an upright position. Furthermore, as shown in Fig. Figure 2 shows the actuating lever 540, which is used to rotate the backrest 12 in the folding direction. In this case, the actuation of the actuating lever 540 can be a first actuation to sequentially actuate the first drive guide 510 to the third drive guide 530 in order to switch the operating mode from electric mode to manual mode.

[0078] In other words, when the actuating lever 540 is rotated by pushing, as in the Fig. 5 and Fig. As shown in Figure 6, the second rope C2 is pulled. When the second rope C2 is pulled in this way, the first drive guide 510 is rotated counterclockwise (see Figure 6). Fig. 3 and Fig. 4) In this way, when the first drive guide 510 is rotated, the locking element 512 rotates the projection piece 522 (see Fig. 7 and Fig. 8), and the first rope C1 is moved in a direction in which the first rope C1 is pulled by the rotation of the second drive guide 520.

[0079] As a result, as in Fig. As shown in Figure 11, when the first cable C1 is pulled, the first bracket 532 and the second bracket 534 are rotated successively along the reference axes A1 and A2, respectively, and the second bracket 534 presses on the pin element 420. Accordingly, the main body 410 is moved downwards into the second position, and the clutch 304 selectively presses on the pinion 302. In this way, the upper rail 200 attached to the seat cushion 10 can be moved in the forward and reverse directions of the lower rail 100 according to the selectively switched / changed manual mode.

[0080] Meanwhile, the 500-series control module, as shown in the Fig. 19 and Fig. Figure 20 shows a switching guide 550 which is connected to the backrest 12 and is configured to transmit a drive force to switch the position of the backrest 12 from the first position, which corresponds to the electric mode, to the second position, which corresponds to the manual mode.

[0081] This means that the switching mechanism 550 is configured so that the backrest 12, which has an electric tilt function, can be selectively switched from automatic mode to manual mode, for example, when the second-row seat needs to be moved forward to allow a passenger in the third row to enter or exit the vehicle. In this case, the passenger in the third row can quickly enter or exit the vehicle by adjusting the angle of the backrest 12 according to the manual mode of the backrest 12.

[0082] For this purpose, the switching guide 550 can have a support element (e.g. holding element) 552, a first rotary element 554, a second rotary element 556 and a third rotary element 558.

[0083] As in Fig. As shown in 20, the support element 552 is rotatably elastically coupled to the backrest 12.

[0084] More precisely, the support element 552 can be rotatably coupled to the backrest 12 by means of a return spring (not shown). If the support element 552 is selectively separated / decoupled from the first rotating element 554, the backrest 12 can be rotated in its folding direction by the elastic return force acting on / via the return spring (not shown).

[0085] Furthermore, the first rotating element 554 has a projecting locking piece 554a configured to be inserted into the support element 552, and a locking groove 554b formed at a location facing / opposite the locking piece 554a, and is designed to be axially rotatable (see Fig. 20).

[0086] The first rotating element 554 can be arranged such that it is locked to the support element 552 by the locking piece 554a in the first position, which corresponds to the electric mode, and can be arranged such that it is unlocked from the support element 552 in the second position, which corresponds to the manual mode.

[0087] Furthermore, the second rotary element 556 is arranged such that it is engaged / captured by the first rotary element 554 and is selectively inserted into the locking groove 554b by the latter's rotation. Accordingly, the first rotary element 554 is guided and rotated by the second rotary element 556 to perform the switching / changeover from the first position to the second position. In this way, the first rotary element 554 is unlocked from the support element 552.

[0088] In other words, the second rotating element 556 is shaped to match the shape of the locking groove 554b and is positioned to lock at the entrance of the locking groove 554b. When the second rotating element 556 is rotated in conjunction with the rotation of the third rotating element 558, the second rotating element 556 is inserted into the locking groove 554b to guide the first rotating element 554 in a downward direction and is rotated axially by elasticity. The first rotating element 554 is then unlocked from the support element 552.

[0089] As in Fig. As shown in Figure 19, the third rotary element 558 is coupled to the second rotary element 556 at a point where the third rotary element 558 and the second rotary element 556 are opposite each other via the same axis of rotation and is connected to an actuating cable C3, so that it is connected to the actuating lever 540 via the actuating cable C3.

[0090] Here, the actuating lever 540 is attached to at least one of the seat cushions 10 and / or the backrest 12. Preferably, the actuating lever 540 can be, as in Fig. 18, are attached to the backrest 12 and connected to the third rotary element 558 via the actuating cable C3. Alternatively, as shown in Fig. As shown in Figure 19, the actuating lever 540 is attached to the seat cushion 10 and is connected to the third rotary element 558 via an actuating rope C3'.

[0091] It is described in turn how the backrest 12 switches / changes from electric mode to manual mode based on the configuration of the above-mentioned switching guide 550.

[0092] For example, when a passenger sitting in the third row enters or exits the vehicle, an actuator 1 is actuated to move the second-row seat forward. In this case, a locking guide 559 connected to the actuator 1 is also actuated to rotate the locking module 600, and a sliding motor 2 is driven to move the upper rail 200 according to the electric mode.

[0093] When the upper rail 200 is moved, the backrest 12 is simultaneously rotated in the direction in which it folds down, according to the electric mode. If the backrest 12 needs to be switched from electric mode to manual mode so that the passenger sitting in the third row can quickly get in or out, as described in the Fig. 18 and Fig. Figure 19 shows that the actuation of the switching guide 550 by the actuating rope C3 or C3' can be carried out selectively by actuating the actuating lever 540 in the direction of pull.

[0094] When the switching guide 550 is actuated, the second rotary element 556, which is rotated in conjunction with the rotation of the third rotary element 558, is located as shown in Fig. 21 shows it in a position where it is / can be engaged / captured by the first rotating element 554. In this state, as described above, when the third rotating element 558 is rotated by actuating the actuating lever 540 in the pulling direction, the second rotating element 556 is inserted into the locking groove 554b and locked therein, as shown in Fig. 22 shown.

[0095] Accordingly, the first rotating element 554 is rotated axially in one direction away from the support element 552, and the locking piece 554a is sequentially unlocked from the support element 552. In this case, the support element 552 is freely rotated into a defined position by an elastic restoring force acting on / via the return spring (not shown) of the support element 552, so that the backrest 12 can be quickly rotated in its folding direction.

[0096] In the present embodiment, the backrest 12, which is driven in electric mode, can thus be driven / operated in manual mode by selectively actuating the switching guide 550, and the backrest 12 can be easily switched from electric mode to manual mode. In this way, the passenger sitting in the third row seat can quickly enter or exit the vehicle, thereby improving user satisfaction.

[0097] In this way, after the backrest 12 has been switched from electric mode to manual mode, when the backrest 12 is rotated in the folding direction by the elastic restoring force acting on / via the return spring (not shown) of the support element 552, as shown in Fig. As shown in Figure 17, the guide module 500 is actuated to transmit a drive force that moves the drive module 400 from the first position, corresponding to the electric mode, downwards to the second position, corresponding to the manual mode. More precisely, as described above, the first drive guide 510 is rotated counterclockwise (see Figure 17). Fig. 3 and Fig. 4). Accordingly, the locking element 512 rotates the projection piece 522 (see Fig. 7 and Fig. 8) by rotating the first drive guide 510, and then the first rope C1 is moved in its direction of pull by rotating the second drive guide 520.

[0098] As a result, as in Fig.As shown in Figure 11, when the first cable C1 is pulled, the first bracket 532 and the second bracket 534 are rotated successively along the reference axes A1 and A2, respectively, and the second bracket 534 presses on the pin element 420. Accordingly, the main body 410 is moved downwards into the second position, and then the clutch 304 selectively presses on the pinion 302, so that the seat cushion 10, together with the backrest 12, is / can be selectively switched from electric mode to manual mode. Consequently, the upper rail 200 can be moved forwards and backwards in the direction of the lower rail 100, according to the manual mode.

[0099] According to the present disclosure / invention, to switch an operating mode from an electric mode to a manual mode, a backrest is first rotated in the folding direction by actuating a lever, and a rope is pulled by rotating the backrest. Subsequently, a first bracket and a second bracket are rotated successively to press a pin element and move an input device. In this case, a pinion movable along a rack is selectively pressed by a clutch, thereby allowing a seat, which has a mechanical connection structure, to be easily switched from electric mode to manual mode.

[0100] Furthermore, the present disclosure / invention enables the operation of the seat according to the electric mode or the manual mode through the mechanical connection structure, thereby achieving a cost reduction and stable operation compared to a seat with an electronic connection structure.

[0101] Since the present disclosure / invention also makes it possible for the backrest, together with a seat cushion, to be switched either into electric mode or manual mode, a passenger sitting in the back seat can quickly enter or exit the vehicle, thereby improving user satisfaction.

[0102] As can be seen from the above description, the present disclosure / invention provides a long sliding rail system for a vehicle seat, configured such that an operating mode is switched from an electric mode to a manual mode by first rotating a backrest in a direction in which the backrest is folded down by actuating a lever, pulling a rope by rotating the backrest, sequentially rotating a first bracket and a second bracket to press a pin element and move an input device, and selectively pressing a pinion movable along a rack by means of a clutch. By such a structural configuration, the long sliding rail system enables a seat with a mechanical linkage structure to easily switch from electric mode to manual mode.

[0103] Furthermore, the long sliding rail system allows the seat to be operated in electric mode or in manual mode through the mechanical connection structure, resulting in cost reduction and stable operation compared to a seat with (only) an electronic connection structure.

[0104] Furthermore, the long sliding rail system allows the backrest, along with a seat cushion, to be switched between electric and manual modes, enabling a passenger in the back seat to quickly enter or exit the vehicle, thus improving user satisfaction.

[0105] The present disclosure / invention has been described in detail with reference to the preferred embodiments shown in the drawings, which are for illustrative purposes only. Those skilled in the art will recognize that various modifications can be made to the embodiments and that all or some of the embodiments can be selectively combined. Therefore, the actual technical scope of protection of the present disclosure / invention should be defined by the scope of the accompanying claims.
