Description

Technical Field

[0001] The present disclosure relates to a seat for a moving vehicle that can be changed in the sitting direction. Background Art

[0002] Moving vehicles (including vehicles with occupants sitting) are provided with seats to ensure the convenience of the occupants. The seats allow the occupants to sit in a comfortable position so that the occupants do not get fatigued even during a long journey.

[0003] The seats are fixed in position in the vehicle compartment, and the occupants need to manually adjust the position of the seat cushion and the position of the seat backrest.

[0004] Recently, purpose-built vehicles (PBVs) have been developed as ground vehicles based on electric vehicles. PBVs are moved by electric wheels that can move freely in 360 degrees instead of the wheels of the vehicle. PBVs are not only used as means of transportation but also provide personalized services to the occupants when they travel to their destinations. The personalized design of PBVs means that they can act as urban shuttles, provide leisure spaces such as restaurants, cafes, and hotels, and can be transformed into various spaces such as hospitals, pharmacies, and other basic social facilities. So far, the interior of the vehicle body can be customized using modular products to suit its purpose.

[0005] However, since the interior space needs to be customized for various usage purposes, it is necessary to change the sitting direction of the seat.

[0006] However, since the seats are fixed in position, it is inconvenient to remove the seats to change their positions.

[0007] The information included in this background art of the present disclosure is only for enhancing the understanding of the general background art of the present disclosure and may not be regarded as an admission or suggestion in any form that this information forms the prior art known to those skilled in the art.

[0051] Hereinafter, a seat for a moving vehicle according to an exemplary embodiment of the present disclosure will be described with reference to the accompanying drawings. In addition, as an example, for the purpose of helping to understand the present disclosure hereinafter, the term "moving vehicle" may refer to a moving vehicle.

[0052] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a seat for a moving vehicle according to an exemplary embodiment of the present disclosure includes: a guide rail 100 disposed on a floor surface; a support part 200 movably mounted on the guide rail 100; a link part 300 rotatably disposed on the support part 200 and including a first connection part 310 and a second connection part 320 spaced apart from a rotation center 330 of the link part 300; a backrest frame 400 tiltably disposed on the support part 200 and including a first operation part 410 to which the first connection part 310 of the link part 300 is rotatably engaged; and a seat cushion frame 500 rotatably disposed on the support part 200 and including a second operation part 510 to which the second connection part 320 of the link part 300 is rotatably engaged, the seat cushion frame 500 configured to rotate in cooperation with the tilting operation of the backrest frame 400 through the link part 300.

[0053] The guide rail 100 is fixed to an inner floor surface and extends in a straight shape or a curved shape to provide a movement path for the support part 200.

[0054] The support part 200 is slidably connected to the guide rail 100. A seat track structure may be used as the support part 200. Accordingly, the moving position of the support part 200 may be changed along the guide rail 100. The position of the moving support part 200 may be fixed by a locking structure included in the seat track structure. Since the seat track structure is a common technology, a detailed description of its structure will be omitted.

[0055] According to an exemplary embodiment of the present disclosure, the backrest frame 400 and the seat cushion frame 500 are disposed on the support part 200. The backrest frame 400 and the seat cushion frame 500 are connected by the link part 300 and operate in cooperation with each other.

[0056] The link part 300 is rotatably disposed on the support part 200 and includes a first connection part 310 and a second connection part 320.

[0057] The backrest frame 400 may be rotatably and hingedly connected to the support part 200 and connected to the first connection part 310 of the link part 300 through the first operation part 410. In an exemplary embodiment of the present disclosure, the seat is configured such that an occupant can sit on the seat in the forward / backward direction of the seat. Accordingly, padding may be applied to the front surface and the rear surface of the backrest frame 400.

[0058] The seat cushion frame 500 can be rotatably and hingedly connected to the support part 200, and is connected to the second connection part 320 of the link part 300 through the second operation part 510. In an exemplary embodiment of the present disclosure, the seat is configured such that an occupant can sit on the seat in the forward / backward direction of the seat. Therefore, padding can be applied to two opposite surfaces of the seat cushion frame 500.

[0059] As described above, the first connection part 310 of the link part 300 is connected to the first operation part 410, and the second connection part 320 of the link part 300 is connected to the second operation part 510, such that when the backrest frame 400 or the seat cushion frame 500 rotates, the backrest frame 400 and the seat cushion frame 500 can rotate in coordination with the rotation of the link part 300.

[0060] As described above, according to an exemplary embodiment of the present disclosure, the state in which an occupant can sit on the seat in two directions can be achieved through the cooperative structure between the backrest frame 400 and the seat cushion frame 500 by the link part 300, so that the storage convenience of the seat and the use convenience of the seat can be ensured.

[0061] According to an exemplary embodiment of the present disclosure, the backrest frame 400 can be arranged on the outer surface of the support part 200, the seat cushion frame 500 can be arranged on the inner surface of the support part 200, the link part 300 can be provided on the outer surface of the support part 200, the first connection part 310 can extend outward and be connected to the first operation part 410 of the backrest frame 400, and the second connection part 320 can extend inward and be connected to the second operation part 510 of the seat cushion frame 500.

[0062] As Figure 3 shown, according to an exemplary embodiment of the present disclosure, the backrest frame 400 and the seat cushion frame 500 are provided on the support part 200. In this case, the support part 200 can be provided as a pair of support parts 200, a pair of end parts of the backrest frame 400 are provided on the outer surfaces of the two support parts 200, and the seat cushion frame 500 can be arranged inside the two support parts 200 and is provided on the inner surface of the support part 200. Therefore, the backrest frame 400 and the seat cushion frame 500 can be provided on the support part 200 without interfering with each other.

[0063] The link part 300 can be respectively provided on the two support parts 200 and connected to the backrest frame 400 and the seat cushion frame 500.

[0064] Accordingly, the first connection portion 310 of the link portion 300 extends outwardly and is connected to the first operation portion 410 of the backrest frame 400, and the second connection portion 320 extends inwardly at a position where the second connection portion 320 does not interfere with the support portion 200, and is connected to the second operation portion 510 of the seat cushion frame 500.

[0065] Accordingly, the backrest frame 400 and the seat cushion frame 500 can be connected by the link portion 300 to operate in cooperation with each other, such that the backrest frame 400 and the seat cushion frame 500 can rotate simultaneously.

[0066] Meanwhile, the lower portion of the backrest frame 400 can be rotatably provided on the support portion 200 to be disposed below the link portion 300, and the first operation portion 410 can be provided to be spaced apart from the point where the support portion 200 is provided.

[0067] As Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown in, the lower portion of the backrest frame 400 is rotatably and hingedly connected to the support portion 200, and the point 250 to which the support portion 200 is connected can be positioned below the link portion 300. Accordingly, when the backrest frame 400 rotates, the link portion 300 can rotate along the rotation radius of the backrest frame 400, and the seat cushion frame 500 can also rotate through the link portion 300.

[0068] In addition, the first operation portion 410 can be positioned to be spaced apart from the point 250 where the backrest frame 400 is mounted on the support portion 200 to be connected to the first connection portion 310 of the link portion 300, such that the link portion 300 can rotate by the rotation of the backrest frame 400 while including the same rotation radius.

[0069] Meanwhile, as can be seen from Figure 5 , the point 550 where the seat cushion frame 500 is provided on the support portion 200 can be arranged to be offset toward either side in the longitudinal direction, and when the point 550 where the seat cushion frame 500 is provided on the support portion 200 is offset, the second operation portion 510 can be spaced apart from the point 550 where the seat cushion frame 500 is provided on the support portion 200 in the direction in which the length of the seat cushion frame based on the point 550 where the seat cushion frame 500 is provided on the support portion 200 is shorter.

[0070] As described above, since the point 550 where the seat cushion frame 500 is disposed on the support portion 200 is arranged to be offset, the seat cushion frame 500 is divided into a seating surface with a larger area and a seating surface with a relatively smaller area. In this case, the seating direction of the seat cushion frame 500 can be changed according to the position where the seating surface with a larger area is deployed, so that the occupant can sit on the seating surface with a larger area.

[0071] The second operation portion 510 is formed on one side of the seating surface with a smaller area of the seat cushion frame 500 in the direction of the shorter length of the seat cushion frame 500. Therefore, the seat cushion frame 500 can rotate in cooperation with the rotation of the link portion 300, so that the occupant can sit on the seating surface with a larger area, and the link portion 300 does not interfere with the occupant.

[0072] Therefore, the direction of the seating surface with a larger area of the seat cushion frame 500 can be changed according to the direction in which the seat cushion frame 500 rotates in cooperation with the rotation of the backrest frame 400 and the link portion 300, so that the seating direction can be selectively changed between two directions.

[0073] Meanwhile, the first connection portion 310, the first operation portion 410, the second connection portion 320, and the second operation portion 510 can be respectively configured as protrusions or slits and define an insertion structure.

[0074] That is, the connection structure between the first connection portion 310 and the first operation portion 410 and the connection structure between the second connection portion 320 and the second operation portion 510 are connected to each other by a structure in which the protrusion is inserted into the slit. Therefore, the backrest frame 400 and the seat cushion frame 500 rotate as the protrusion rotates and moves in the slit.

[0075] In the description of the present disclosure, the first connection portion 310 and the second connection portion 320 of the link portion 300 are configured as protrusions, and the first operation portion 410 of the backrest frame 400 and the second operation portion 510 of the seat cushion frame 500 are configured as slits. Of course, the first connection portion 310 and the second connection portion 320 can be configured as slits, and the first operation portion 410 and the second operation portion 510 can be configured as protrusions. The same operating principle can be applied.

[0076] Each of the slits related to the first connection portion 310, the first operation portion 410, the second connection portion 320, and the second operation portion 510 can extend to define the movement path of the protrusion.

[0077] In an exemplary embodiment of the present disclosure, the first operation portion 410 and the second operation portion 510 may be configured as slits. The first operation portion 410 extends in the longitudinal direction of the backrest frame 400, and the second operation portion 510 extends in the longitudinal direction of the seat cushion frame 500.

[0078] Therefore, in a state where the first connection portion 310 configured as a protrusion is inserted into the first operation portion 410, the backrest frame 400 can also rotate along the rotation radius of the link portion 300, and the tilting position of the backrest frame 400 can be changed according to the position where the protrusion moves in the slit.

[0079] In addition, in a state where the second connection portion 320 configured as a protrusion is inserted into the second operation portion 510, the seat cushion frame 500 can also rotate along the rotation radius of the link portion 300, and the rotation position of the seat cushion frame 500 can be changed according to the position where the protrusion moves in the slit.

[0080] In the case of the slits related to the first connection portion 310, the first operation portion 410, the second connection portion 320, and the second operation portion 510, in a state where the backrest frame 400 and the seat cushion frame 500 rotate on a line perpendicular to the up / down direction, the protrusion of the first connection portion 310 and the protrusion of the first operation portion 410 can be positioned at the uppermost end portion of the slit, and the protrusion of the second connection portion 320 and the protrusion of the second operation portion 510 can be positioned at the lowermost end portion of the slit.

[0081] Reference Figure 8 and Figure 9 , in a stored state where the backrest frame 400 and the seat cushion frame 500 rotate on a line perpendicular to the up / down direction, the first connection portion 310 as a protrusion is positioned at the uppermost end portion of the first operation portion 410 as a slit, and the second connection portion 320 as a protrusion is positioned at the lowermost end portion of the second operation portion 510 as a slit, so that the backrest frame 400 and the seat cushion frame 500 can rotate in opposite directions.

[0082] In addition, one end portion of the link portion 300 is rotatably provided on the support portion 200, and the first connection portion 310 and the second connection portion 320 are sequentially spaced apart from each other toward the other end portion. Therefore, when the link portion 300 rotates around the rotation center 330, it is possible to ensure that the rotation radius of the second connection portion 320 is larger than the rotation radius of the first connection portion 310. In this case, in the stored state of the backrest frame 400 and the seat cushion frame 500, one direction of the link portion 300 may be the downward direction, and the other direction of the link portion 300 may be its upward direction.

[0083] Therefore, the length of the slit in each of the first connection part 310 and the first operation part 410 is shorter than the length of the slit in each of the second connection part 320 and the second operation part 510, so that the rotation amount of the seat cushion frame 500 can be greater than the tilt amount of the backrest frame 400.

[0084] That is, according to the movement amount of the first connection part 310 moving along a relatively small rotation radius, the length of the first operation part 410 configured as a slit is configured to be a relatively short length, so that the tilt angle of the backrest frame 400 can be changed to support the back of the occupant.

[0085] In addition, according to the movement amount of the second connection part 320 moving along a relatively large rotation radius, the length of the second operation part 510 configured as a slit is configured to be a relatively long length, so that the angle of the seat cushion frame 500 can be changed so that the occupant can sit on the seat cushion frame 500 in a state where the seat cushion frame 500 is upright.

[0086] As described above, according to the exemplary embodiment of the present disclosure, the rotation amounts of the backrest frame 400 and the seat cushion frame 500 can be set based on the positions of the first connection part 310 and the second connection part 320 forming the link part 300 and the lengths of the second operation part 510 and the first operation part 410. Therefore, the backrest frame 400 and the seat cushion frame 500 can be implemented as seats on which an occupant can sit.

[0087] The operations of the present disclosure can be performed as follows.

[0088] In the stored state as shown in Figure 7 (where the backrest frame 400 and the seat cushion frame 500 are deployed on a vertical line), the first connection part 310 as a protrusion is positioned at the uppermost end part of the first operation part 410 as a slit, and the second connection part 320 as a protrusion is positioned at the lowermost end part of the second operation part 510 as a slit, as shown in Figure 8 and Figure 9 shown.

[0089] In this case, when the backrest frame 400 rotates in any direction as shown in Figure 10 shown, the first connection part 310 as a protrusion moves downward in the opposite direction in the first operation part 410 as a slit according to the rotation of the backrest frame 400, as shown in Figure 11 and Figure 12 shown. At the same time, when the first connection part 310 moves in the first operation part 410, the link part 300 rotates, and the second connection part 320 as a protrusion moves in the opposite direction in the second operation part 510 as a slit, so that the seat cushion frame 500 rotates.

[0090] Therefore, during the reclining operation of the backrest frame 400, the seat cushion frame 500 rotates in cooperation with the backrest frame 400 through the link part 300, so that the backrest frame 400 and the seat cushion frame 500 can be switched to the state where the occupant can sit.

[0091] In addition, when the backrest frame 400 rotates in the other direction as shown in Figure 13 , the first connecting part 310 as a protrusion moves downward in the opposite direction in the first operating part 410 as a slit according to the rotation of the backrest frame 400, as shown in Figure 14 and Figure 15 . At the same time, when the first connecting part 310 moves in the first operating part 410, the link part 300 rotates, and the second connecting part 320 as a protrusion moves in the opposite direction in the second operating part 510 as a slit, so that the seat cushion frame 500 rotates.

[0092] As described above, according to the exemplary embodiment of the present disclosure, the link part 300 rotates according to the rotation direction of the backrest frame 400, and the seat cushion frame 500 rotates in cooperation with the link part 300. Therefore, the backrest frame 400 and the seat cushion frame 500 rotate in opposite directions by using the connection structure of the connecting part and the operating part, so that the seat posture changes. In addition, the sitting direction changes between two directions according to the rotation directions of the backrest frame 400 and the seat cushion frame 500, so that the usability can be improved.

[0093] At the same time, as can be seen from Figure 5 and Figure 6 , the backrest frame 400 can be rotatably provided on the support part 200 through the recliner 600.

[0094] The recliner 600 includes the function of adjusting the reclining angle of the backrest frame 400 and locking the backrest frame 400, and the backrest frame 400 is provided on the support part 200 through the recliner 600, so that the reclining angle of the backrest frame 400 can be adjusted and fixed.

[0095] The recliner 600 may include: a housing; a locking plate coupled to a rotating shaft in the housing; a fixing part configured to limit the relative rotation between the locking plate and the housing; an elastic part configured to apply an elastic force to the locking plate in the direction in which the fixing part is caught and coupled; and a lever configured to release the fixing part. The detailed structure of the recliner 600 can be used in various embodiments.

[0096] In this case, a cable can be connected to the lever so that the occupant can directly perform the locking or unlocking operation manually. Alternatively, a motor can be connected so that the locking or unlocking operation can be automated.

[0097] At the same time, as inFigure 16 As shown, the stopper 210 may be formed on the support portion 200 to limit the rotational position of the link portion 300. The stopper 210 may be formed at a position where the link portion 300 contacts the stopper 210 when the seat cushion frame 500 rotates at a deployment angle at which an occupant can sit on the seat cushion frame 500.

[0098] The stopper 210 is configured to control the rotational positions of the backrest frame 400 and the seat cushion frame 500. The stopper 210 may be formed in a wedge shape on the support portion 200. When the backrest frame 400 and the seat cushion frame 500 rotate in a state where an occupant can sit on the backrest frame 400 and the seat cushion frame 500, the stopper 210 may contact the rotating link portion 300 and be supported by the link portion 300.

[0099] Therefore, when the link portion 300 contacts the stopper 210, the rotation of the link portion 300 is restricted, the position of the link portion 300 is fixed, and the positions of the backrest frame 400 and the seat cushion frame 500 are controlled so that the positions of the backrest frame 400 and the seat cushion frame 500 can be maintained for an occupant to sit on the backrest frame 400 and the seat cushion frame 500.

[0100] In addition, the link portion 300 may contact the stopper 210 and implement a support structure so that the postures of the backrest frame 400 and the seat cushion frame 500 can be stabilized.

[0101] Meanwhile, as Figure 16 shown, the latch 520 may be provided on the seat cushion frame 500, and the latch 520 may be configured to connect the link portion 300 when the seat cushion frame 500 rotates at a deployment angle at which an occupant can sit on the seat cushion frame 500.

[0102] The latch 520 may be provided on the second operation portion 510 and configured to control the rotational positions of the backrest frame 400 and the seat cushion frame 500.

[0103] Figure 16 An exemplary embodiment is shown in which the second connection portion 320 is configured as a groove and the second operation portion 510 is configured as a protrusion.

[0104] In this case, the latch 520 is configured to fix the position of the link part 300 when the link part 300 is connected. The latch 520 is provided at a position where the latch 520 can be connected to the link part 300 when the link part 300 rotates in coordination with the rotation of the seat cushion frame 500 in a state where an occupant can sit on the seat cushion frame 500. The latch 520 can be provided as a single latch 520 or a plurality of latches 520. According to an exemplary embodiment of the present disclosure, since the sitting direction changes between two directions, a pair of latches 520 can be configured based on the two directions.

[0105] Therefore, when the backrest frame 400 and the seat cushion frame 500 rotate and switch to a state where an occupant can sit on the backrest frame 400 and the seat cushion frame 500, the link part 300 also rotates and moves to a position where the link part 300 can be connected to the latch 520, and the link part 300 is fixed by being connected to the latch 520, so that the positions of the backrest frame 400 and the seat cushion frame 500 can be controlled. Therefore, the positions of the backrest frame 400 and the seat cushion frame 500 can be maintained so that an occupant can sit on the backrest frame 400 and the seat cushion frame 500.

[0106] Meanwhile, as can be seen from Figure 1 and Figure 2 the headrest 420 can be provided on the upper part of the backrest frame 400, and the headrest 420 can be rotatably provided on the backrest frame 400.

[0107] So far, the fixed shaft a can be provided on the upper side of the backrest frame 400, and the headrest 420 can be rotatably engaged with the fixed shaft. When the headrest 420 rotates 180° around the fixed shaft a, the position of the headrest can be changed between two directions. According to the embodiment of the seat, the rotation angle of the headrest 420 can be set to various angles.

[0108] Therefore, the occupant can be stably supported by changing the position of the headrest 420 according to the change in the sitting direction of the backrest frame 400 and the seat cushion frame 500.

[0109] Meanwhile, the seat cushion frame 500 can be divided into a plurality of seat cushion frames 500. Any one of the seat cushion frames 500 can be provided on the support part 200, and the remaining seat cushion frames 500 can be rotatably engaged with the seat cushion frame 500 provided on the support part 200.

[0110] As described above, in a state where the seat cushion frame 500 includes a plurality of seat cushion frames 500, the seat cushion frame 500 can be configured to be folded or unfolded. When the seat cushion frame 500 is folded, the storage space can be reduced. When the seat cushion frame 500 is unfolded, an occupant can sit. In addition, the sitting posture of the occupant can be optimized by changing the angle of the seat cushion frame 500.

[0111] According to the seat for a moving vehicle constructed as described above, the sitting direction of the seat can be changed so that the convenience of use of the seat can be ensured, the weight and volume can be reduced by structural simplification, and the manufacturing cost can be reduced.
