[0048] Figure 1 is an exploded view of a swivel seat according to an embodiment of the present disclosure, Figure 2 is a view showing a coupling state of a swivel seat according to an embodiment of the present disclosure, Figure 3 is a view showing an example of applying the swivel seat to a vehicle.

[0049] Referring to Figures 1 to 3 , a swivel seat according to an embodiment of the present disclosure includes: a locking pin 100, each of the locking pins 100 extending in a longitudinal direction; an inner plate 200, configured such that a seat can be coupled to an outer side of the inner plate 200 and the locking pins 100 are received inside the inner plate 200; and an outer plate 300, configured to rotatably receive the inner plate 200 inside the outer plate 300, wherein the outer plate 300 has a plurality of locking pin fixing grooves 310 and 310' respectively formed at a plurality of positions of the outer plate 300 and configured to fix the locking pins 100, one end of each of the locking pins 100 is inserted into a corresponding one of the locking pin fixing grooves, and the locking pins 100 are selectively inserted into a part of the plurality of locking pin fixing grooves 310 and 310' by rotation of the inner plate 200.

[0050] The seat of the present disclosure has a function of rotating in the interior space of a vehicle. When necessary, the seat can be rotated so that a passenger can be seated in a desired direction. At the same time, the seat is prevented from rotating from the desired position of the passenger after the seat rotates. Since it is necessary to reliably ensure the safety of the passenger against a vehicle collision while the vehicle is continuously running, it is necessary to prevent the seat from rotating while the vehicle is running.

[0051] To this end, the present disclosure can provide a device capable of rotating a seat relative to a vehicle body floor or a guide rail provided on the vehicle body floor.

[0052] Specifically, the seat S can be coupled to the outer side of the inner plate 200. A seat coupling hole 210 is formed in one surface of the inner plate 200, and the seat coupling hole 210 is configured such that the seat S can be coupled to the inner plate 200. In this way, when either the seat S or the inner plate 200 rotates, the other component can also rotate. One surface of the inner plate 200 can be a surface facing the seat S.

[0053] The inner plate 200 can be made of metal or plastic and can be formed by injection molding. Since the inner plate 200 is connected to the vehicle seat, the inner plate 200 is preferably made of a material with sufficient rigidity.

[0054] On the other hand, referring to Figure 3 , the swivel seat 1000 including the inner plate 200 is connected to the seat rail R provided on the vehicle floor or directly connected to the vehicle floor, thereby providing the swivel seat 1000 in the vehicle.

[0055] As described above, the swivel seat is installed on the seat rail provided in the vehicle, so that not only can the free movement and free rotation of the seat be realized, but also a vehicle seat that can be placed in various positions in the vehicle can be provided.

[0056] Figure 4 And Figure 5 are diagrams respectively showing the inner plate and the locking pin accommodated in the inner plate. Here, Figure 4 is a diagram showing the upper surface of the inner plate, Figure 5 is a diagram showing the lower surface of the inner plate.

[0057] The locking pin 100 is accommodated in the inner plate 200. The locking pin 100 performs a linear reciprocating motion in the inner plate 200. A locking pin accommodation groove 220 is formed in the inner plate 200, and the locking pin accommodation groove 220 is configured such that the locking pin 100 can be accommodated inside the inner plate 200. The locking pin 100 is accommodated in the locking pin accommodation groove 220 so as to realize the linear reciprocating motion of the locking pin 100 in the locking pin accommodation groove 220. That is, the locking pin accommodation groove 220 serves as the reciprocating motion path of the locking pin 100.

[0058] Therefore, when one end of the locking pin 100 is inserted into the locking pin fixing groove 310 of the outer plate 300, the inner plate 200 is fixed. When one end of the locking pin 100 is separated from the locking pin fixing groove 310, the inner plate 200 becomes rotatable.

[0059] The locking pin is used to fix the inner plate to the outer plate to prevent the inner plate from rotating. Here, in the state where the locking pin is inserted into the locking pin fixing groove of the outer plate, it is necessary to prevent the locking pin from separating from the locking pin fixing groove due to external impact. In addition, the locking pin can be made of metal or plastic to ensure sufficient rigidity, so as to prevent the locking pin from being cut off in the state where the locking pin is inserted into the locking pin fixing groove.

[0060] A pair of locking pins 100 are accommodated inside the inner plate 200 in a state where the locking pins 100 face each other on the same line. However, this structural configuration is only an embodiment, and in some cases, a single locking pin 100 can be provided, or a pair or more pairs of locking pins 100 can be provided.

[0061] When multiple locking pins are provided, the inner plate can be more firmly fixed to the outer plate.

[0062] In this way, one end of the locking pin 100 can be inserted into the locking pin fixing groove 310 formed in the outer plate 300, or one end of the locking pin 100 can be separated from the locking pin fixing groove 310.

[0063] An inner plate accommodating space 320 is formed in the outer plate 300, and the inner plate accommodating space 320 is configured to accommodate the inner plate 200 in the inner plate accommodating space 320, so as to accommodate the inner plate 200 in the outer plate 300. As Figure 6 shown, when one end of the locking pin 100 accommodated in the inner plate 200 is inserted into the locking pin fixing groove 310 of the outer plate 300, the inner plate 200 becomes unable to rotate. On the other hand, as Figure 7 shown, when one end of the locking pin 100 is separated from the locking pin fixing groove 310 of the outer plate 300, the inner plate 200 can rotate within the outer plate 300. Therefore, the inner plate 200 accommodated in the outer plate can rotate.

[0064] One end of the locking pin accommodated in the inner plate 200 is repeatedly inserted into and separated from the outer plate 300. In addition, the outer plate 300 has a locking pin fixing groove 310, and the locking pin fixing groove 310 is configured such that one end of the locking pin 100 can be inserted into the locking pin fixing groove 310 and fixed to the locking pin fixing groove 310, and the inner plate rotates repeatedly within the outer plate. Therefore, the outer plate 300 preferably ensures at least the same rigidity as that of the inner plate 200 or the locking pin 100. More preferably, the outer plate ensures a stronger rigidity than that of the inner plate 200 or the locking pin 100.

[0065] As described above, by accommodating the locking pin 100 in the inner plate 200 and accommodating the inner plate 200 in the outer plate 300, a compact-sized device suitable for rotating a seat can be manufactured. In addition, since the device is made of a material capable of ensuring sufficient rigidity, the risk of damage can be reduced even if a vehicle collision occurs outside the vehicle.

[0066] In addition, since the locking pin 100 is firmly fixed to the outer plate 300, it is possible to prevent the coupling member from separating from the device due to vibrations occurring during vehicle travel, or to prevent vibrations from being transmitted to the seat, thereby providing a comfortable driving experience.

[0067] As Figures 6 to 8As shown, the locking pin fixing grooves 310 and 310' can be formed at equal intervals along the circumference of the outer plate 300. When a user attempts to rotate the seat S coupled to the inner plate 200, one end of the locking pin 100 can be separated from the locking pin fixing groove 310, so that the seat S becomes rotatable. When the seat S rotates, the inner plate 200 rotates, and then the locking pin 100 is inserted into the locking pin fixing groove 310', which is different from the locking pin fixing groove 310 into which the locking pin 100 was previously inserted. In this way, when the inner plate 200 is fixed, the rotation of the seat S can be completed.

[0068] Specifically, the locking pin fixing grooves 310 are formed along the circumference of the outer plate 300 and are respectively configured such that the distance between the locking pin fixing grooves 310 into which the locking pin 100 can be inserted is not large enough in the counterclockwise and clockwise directions. Therefore, even if an impact is applied to the vehicle body from any direction, the inner plate 200 can be stably fixed to the outer plate.

[0069] In addition, when a plurality of locking pin fixing grooves 310 are formed in the outer plate 300, the seat can be rotatable to achieve a desired viewing angle. In the drawings, four locking pin fixing grooves 310 are shown and the seat can be rotated 90 degrees. On the other hand, four or more locking pin fixing grooves 310 can be provided so that the seat rotates at an angle smaller than 90 degrees.

[0070] As described above, a brief description of the operation sequence of the vehicle seat according to an embodiment of the present disclosure is given. Hereinafter, the specific operation sequence will be described.

[0071] First, in order to put the seat S in a rotatable state, one end of the locking pin 100 is separated from the locking pin fixing groove 310.

[0072] Figure 6 and Figure 7 are diagrams respectively showing the results of observing the state in which one end of the locking pin 100 is separated from the locking pin fixing groove 310 from above. Referring to Figure 6 and Figure 7 , one end of the locking pin 100 can be separated from the locking pin fixing groove 310 by applying a release force C to a rod plate 400, which will be described later. Therefore, the inner plate 200 enters a rotatable state.

[0073] Here, the release force C refers to an external force applied by a user or other device to the rod plate 400.

[0074] Specifically, referring to Figure 4 and Figure 5, a first guiding protrusion 110 is formed on one surface of the locking pin 100, and the first guiding protrusion 110 is formed to protrude outward from the inner plate 200. In addition, a slot hole 510 is formed in the locking pin bracket 500, and the slot hole 510 is configured such that the first guiding protrusion 110 of the locking pin 100 can be movable in the slot hole 510. Here, the locking pin bracket 500 can be received in a locking pin bracket receiving groove 230 formed outside the inner plate 200. One surface of the locking pin 100 can be the surface facing the seat S. The locking pin bracket 500 is a component configured to urge the locking pin 100 to move and rotate through the slot hole 510 formed in the locking pin bracket 500, and is a necessary component for separating the locking pin 100 inserted into the locking pin fixing groove 310 from the locking pin fixing groove 310.

[0075] The locking pin 100 is coupled to the locking pin bracket 500 such that the first guiding protrusion 110 is received in the slot hole 510 formed in the locking pin bracket 500. Therefore, when the locking pin bracket 500 rotates, the first guiding protrusion 110 moves in the slot hole 510, thereby realizing the linear reciprocating motion of the locking pin 100. In this case, a pair of slot holes 510 are formed in a streamlined shape, so that the locking pin 100 can perform a linear reciprocating motion according to the rotation of the locking pin bracket 500.

[0076] The slot hole 510 is preferably formed wider than the width of the first guiding protrusion 110 so that the first guiding protrusion 110 can move smoothly in the slot hole 510, and the first guiding protrusion 110 preferably has an appropriate height so as to be smoothly received in the slot hole 510.

[0077] On the other hand, referring to Figure 1 and Figure 2 , the rotation of the locking pin bracket 500 is performed by a rod plate 400 connected to the locking pin bracket 500 and the inner plate 200. A rod 410 is formed at one end of the rod plate 400, and the rod 410 is configured such that a release force can be applied to the rod 410. That is, a release force is applied to the rod 410, thereby causing the rod plate 400 to rotate.

[0078] The rod plate 400 is connected to the locking pin bracket 500, and the locking pin bracket 500 also rotates through the rotation of the rod plate 400. When the first guiding protrusion 110 received in the locking pin bracket 500 moves along the slot hole 510, the linear motion of the locking pin 100 can be promoted.

[0079] More specifically, the connection relationship between the locking pin bracket 500, the rod plate 400, and the inner plate 200 will be described.

[0080] The rod plate 400 is connected to the locking pin bracket 500. A first connection hole 520 is formed in the locking pin bracket 500, and a second connection hole 420 is formed in the rod plate 400 at a position corresponding to the first connection hole 520. Then, the connecting member L is inserted into the first connection hole 520 and the second connection hole 420 to connect the locking pin bracket 500 to the rod plate 400. In this way, the force applied to the rod plate 400 can also be transmitted to the locking pin bracket 500.

[0081] Since the connecting member L connects the locking pin bracket 500 to the rod plate 400, the connecting member L is required to have sufficient rigidity. In addition, the connecting member L is desirably formed to have a sufficient length so as to completely penetrate the rod plate 400 and the locking pin bracket 500.

[0082] In addition, referring to Figure 2 , the rod plate 400 and the inner plate 200 are connected to each other by a torsion spring 600. Spring connection protrusions 430 are formed on one surface of the rod plate 400, and spring connection protrusions 240 are formed on one surface of the inner plate 200. Here, the torsion spring 600 is connected to the spring connection protrusions 430 and 240. Specifically, one end and the other end of the torsion spring 600 are respectively connected to the spring connection protrusions 430 and 240, thereby connecting the rod plate 400 to the inner plate 200. One surface of the rod plate 400 may be the surface facing the seat S.

[0083] The torsion spring 600 applies a force to the inner plate 200 or the rod plate 400 according to the relative positions of the inner plate 200 and the rod plate 400. That is, the rod plate 400 and the inner plate 200 are rotatably provided, and the torsion spring 600 connecting the rod plate 400 to the inner plate 200 also changes its position according to the rotation of the rod plate 400 and the inner plate 200 (refer to the arrow B shown in Figure 6 ).

[0084] Therefore, when the position of the torsion spring 600 changes, the direction of the force acting on the rod plate 400 and the locking pin bracket 500 also changes, and the force acts on the locking pin 100 in the inward or outward direction of the inner plate 200. Therefore, the locking pin 100 can perform a linear reciprocating motion within the inner plate 200.

[0085] Figures 6 to 9 are diagrams respectively showing the direction A of the force of the torsion spring.

[0086] Hereinafter, the specific direction of the force applied to the locking pin 100 etc. will be described according to the operation sequence of the rotating seat according to the present disclosure.

[0087] First, a description will be given of the process of separating one end of the locking pin 100 from the locking pin fixing groove 310 according to the above connection relationship. Referring to Figure 6 and Figure 7 , Figure 6It is a view showing a state in which the locking pin 100 is forced in the outward direction of the inner plate by the force generated by the torsion spring 600, causing one end of the locking pin 100 to move to the locking pin fixing groove 310.

[0088] That is, the torsion spring 600 applies a force in the clockwise direction, and the rod plate 400 and the locking pin bracket 500 connected thereto are subjected to the force applied in the clockwise direction. Therefore, the locking pin 100 is forced in the outward direction of the inner plate 200.

[0089] At this time, in order to rotate the seat S, when a release force (exceeding the force generated by the torsion spring) is applied to the rod plate 400 in the counterclockwise direction to rotate the rod plate 400 in the counterclockwise direction, the locking pin bracket 500 connected to the rod plate 400 also rotates.

[0090] That is, since the release force applied to the rod plate 400 is greater than the force generated by the torsion spring 600, one end of the locking pin 100 is forced in the direction away from the locking pin fixing groove 310, that is, in the inward direction of the inner plate 200.

[0091] Therefore, the first guide protrusion 110 of the locking pin 100 moves along the slot hole 510 toward the rotation center of the locking pin bracket 500, and one end of the locking pin 100 separates from the locking pin fixing groove 310, thus entering Figure 7 the state shown.

[0092] In addition, referring to Figure 6 and Figure 7 , when one end of the locking pin 100 is completely separated from the locking pin fixing groove 310, the position of the torsion spring 600 is also rotatably changed by the rotation of the rod plate 400. When the position of the torsion spring 600 is rotatably changed, the force applied from the torsion spring 600 to the rod plate 400 and the locking pin bracket 500 acts in the counterclockwise direction.

[0093] That is, as Figure 6 shown, before the rod plate 400 rotates, the force of the torsion spring 600 acts in the clockwise direction, but as Figure 7 shown, when the rod plate 400 rotates, the force of the torsion spring 600 acts in the counterclockwise direction, and the rod plate 400 and the locking pin bracket 500 connected thereto are subjected to the force in the counterclockwise direction. Therefore, the locking pin 100 is forced, prompting the locking pin 100 to move inward of the inner plate 200.

[0094] As described above, when one end of the locking pin 100 is separated from the locking pin fixing groove 310 by applying a release force to the rod plate 400, the seat S connected to the inner plate 200 can be in a rotatable state. In this state, when a rotational force is applied to the seat S to rotate the seat S, the inner plate 200 connected to the seat S can rotate.

[0095] Here, the rotational force refers to the external force applied by the user to the seat to rotate the seat.

[0096] That is, the seat can rotate in the Figure 7 state shown in, and can complete the rotation of the seat by passing through the Figure 8 and Figure 9 states shown in. When the inner plate 200 rotates due to the rotation of the seat, the locking pin 100 accommodated in the inner plate 200 can be inserted into any one of the plurality of locking pin fixing grooves 310. When the locking pin 100 is inserted into any one of the plurality of locking pin fixing grooves 310 without applying a release force to the rod plate 400, the inner plate 200 can be fixed.

[0097] Next, the inner plate 200 rotates due to the rotation of the seat S, and the locking pin 100 is inserted into another locking pin fixing groove 310', thereby completing the rotation of the seat S.

[0098] Referring to Figure 4 and Figure 5 , a second guiding protrusion 120 protruding downward is formed on the lower surface of the locking pin 100. Referring to Figure 1 , a base plate 700 is provided below the inner plate 200, and a guiding portion 710 is formed on the base plate 700, and the guiding portion 710 is configured to contact the second guiding protrusion 120 to move the second guiding protrusion 120.

[0099] In a state where one end of the locking pin 100 is separated from the locking pin fixing groove 310, when the seat S rotates clockwise or counterclockwise, the guiding portion 710 formed on the base plate 700 can push the second guiding protrusion 120 in the direction of the force applied to the seat S, and can apply a force outward from the inner plate 200 to the locking pin 100.

[0100] Figures 10 to 15 are diagrams respectively showing the results of the operation sequence of observing the rotating seat from below. First, referring to Figure 10 and Figure 11 , the locking pin 100 is separated from the locking pin fixing groove 310 by the release force applied to the rod plate 400. Thereafter, the second guiding protrusion 120 contacts the outer peripheral surface of the guiding portion 710 formed on the base plate 700.

[0101] Thereafter, when a rotational force is applied to the seat S, the rotational force is transmitted to the inner plate 200, and the force is also transmitted to the locking pin 100 accommodated in the inner plate 200. Referring to Figures 10 to 13, the direction in which the locking pin 100 moves is determined by the force transmitted through the rotation of the seat S to the locking pin 100. In addition, the second guiding protrusion 120 of the locking pin 100 continuously moves in the direction in which the locking pin 100 moves due to the reaction force generated on the outer peripheral surface of the guiding portion 710 until the second guiding protrusion 120 separates from the outer peripheral surface of the guiding portion 710.

[0102] Figures 16 to 18 are diagrams respectively showing the movement of the second guiding protrusion 120 of the locking pin 100 through the shape of the outer peripheral surface of the guiding portion 710. Refer to Figures 16 to 18 , the second guiding protrusion 120 of the locking pin 100 continuously moves through the shape of the outer peripheral surface of the guiding portion 710 until the second guiding protrusion 120 separates from the outer peripheral surface of the guiding portion 710.

[0103] Due to the reaction force from the guiding portion 710, a force outward from the inner plate 200 is applied to the locking pin 100. In particular, the outer peripheral surface of the guiding portion 710 is formed to have a shape suitable for pushing the second guiding protrusion 120, and the guiding portion 710 applies a reaction force to the second guiding protrusion 120. Therefore, a force outward from the inner plate 200 can be applied to the locking pin 100.

[0104] Thereafter, when in the Figure 12 state shown, when the second guiding protrusion 120 and the outer peripheral surface of the guiding portion 710 are separated from each other, one end of the locking pin 100 is inserted into the locking pin fixing groove 310' which is different from the locking pin fixing groove 310 into which one end of the locking pin 100 was previously inserted (refer to Figure 7 ). Thereafter, the locking pin 100 is coupled to the outer plate 300, and the inner plate 200 stops rotating, thereby completing the rotation of the seat S.

[0105] It is apparent from the above description that the present disclosure provides a swivel seat having the following advantages: the vehicle seat can be rotated, and the device capable of rotating the vehicle seat is simple and compact in size.

[0106] In particular, the user can easily control the locked state and the unlocked state of the swivel seat, and the connection rigidity between the swivel seat and the vehicle body can be stably maintained in the locked state, thereby ensuring the safety of the passengers to the maximum extent in the event of a vehicle collision.

[0107] The present disclosure has been described in detail with reference to the preferred embodiments of the present disclosure. However, those skilled in the art will understand that these embodiments can be changed without departing from the principles and spirit of the present disclosure, and the scope of the present disclosure is defined by the appended claims and their equivalents.
