Description

Technical Field

[0001] The present invention relates to a seat back table for vehicles, and more specifically, to a seat back table for vehicles that can be fixed in a position unfolded from the seat back. Background Technology

[0002] Typically, to provide convenience for passengers, the interior of a vehicle is equipped with various storage or support devices.

[0003] In such storage or support devices, a seatback table is a convenient device that can be rotatably mounted on the back of the front seat so that passengers sitting in the back can place various small items.

[0004] Typically, a seat can consist of a seat cushion for passengers to sit on and a seat back that is rotatably connected to the seat cushion to support the passenger's back. A seat back table can be installed behind the seat back so that passengers sitting in the back can place small items.

[0005] This chair back table is designed to fold or unfold behind the chair back as needed.

[0006] However, in the case of the seat back as described above, since it was previously impossible to fix it in the unfolded position, there were many inconveniences.

[0007] In other words, since the existing seat back tables cannot be adjusted in terms of unfolding angle, they can only be fixed at the preset maximum unfolding position. Therefore, when the angle of the front row seat back changes, items placed on the seat back tables may fall off, which may cause various problems. Summary of the Invention

[0008] (a) Technical problems to be solved The purpose of this invention is to provide a seat back table for vehicles, which, when extended and unfolded from the seat back, allows a sliding gear to selectively engage with a fixed gear by operating an angle adjustment switch, thereby fixing the unfolded position.

[0009] (II) Technical Solution The vehicle seat backrest table according to the present invention is characterized in that it comprises: a backrest panel, installed on the back of the seat back; a backrest table, foldably or unfoldably connected to the backrest panel; a fixing switch, slidably disposed on the backrest table; and a fixing guide, coupled to the backrest table, selectively engaging with a fixing shaft of the backrest table when the fixing switch slides, so as to guide and fix the rotation angle of the backrest table.

[0010] Here, the fixed guide includes: a switch connector connected to the fixed switch; a pair of gear locking pins rotatably engaged about the rotation axis of the switch connector, which, when the switch connector moves, are pressed against the fixed axis and unfold in opposite directions; and a pair of sliding gears engaged to the fixed axis, which, when the gear locking pins unfold, are selectively movable on the fixed axis.

[0011] Each of the sliding gears has gear teeth on its outer side, and the fixed shaft has a fixed gear, each of the fixed gears having gear teeth formed on its inner side, so as to selectively engage with the sliding gear when the sliding gear moves.

[0012] Additionally, the fixed guide includes an elastic member that provides an elastic force for moving the sliding gears in opposite directions, such that when the gear locking pin returns to its initial position, the engagement between the sliding gear and the fixed gear is disengaged.

[0013] In addition, the fixed switch is provided with a switch wire, which extends and connects to the switch connector.

[0014] Furthermore, when the fixed switch moves forward in the operating slot provided on the backrest table, the switch line moves forward, causing the gear locking pin to unfold, thereby fixing the rotation angle of the backrest table.

[0015] Here, when the fixed switch moves backward in the operating slot, the switch line moves backward, causing the gear locking pin to return to its initial position, thereby releasing the fixation of the rotation angle of the backrest table.

[0016] On the other hand, the backrest table is connected to the backrest panel via a four-section linkage structure including an upper linkage and a lower linkage.

[0017] Furthermore, the vehicle seat backrest table according to the present invention further includes: an extension module mounted on the backrest panel, such that the backrest table can be selectively unfolded.

[0018] This lead-out module includes: an operation button exposed on the surface of the backrest panel and configured to be resiliently movable in a button housing when pressurized; and a locking hook engaged in a locking groove of the backrest table and selectively rotated by movement of the operation button to disengage from the locking groove.

[0019] (III) Beneficial Effects The advantage of this invention is that when the seat is extended and unfolded from the backrest, the sliding gear is selectively engaged with the fixed gear by operating the angle adjustment switch, thereby fixing the unfolded position.

[0020] Meanwhile, the advantage of this invention is that when the angle adjustment switch is operated in the fixed unfolded position of the seat back table, the sliding gear is reset to the initial position by the elastic component to disengage from the fixed gear, thereby easily converting the seat back table into a foldable or unfoldable state.

[0040] also, Figure 8 This is a diagram illustrating the rearward movement of a fixed switch in a vehicle seat back table according to an embodiment of the present invention. Figure 9 This is used to illustrate the structure of the lead-out module in the vehicle seat back table according to an embodiment of the present invention. Figure 1a AA section diagram, Figure 10 This is used to illustrate the operation of the lead-out module in the vehicle seat back table according to an embodiment of the present invention. Figure 1b BB cross-sectional view.

[0041] like Figure 1a and Figure 1b As shown, the vehicle seat back table according to this embodiment is configured as a back table 200 that can be selectively folded or unfolded on the back panel 100 mounted on the back of the seat back.

[0042] Here, the backrest table 200 can be adjusted to rotate when unfolded, thus providing convenience for passengers sitting in the back row.

[0043] That is, since the existing backrest table 200 is set to only be able to be folded or unfolded, if the front seat is tilted when it is unfolded from the backrest panel 100, the angle of the backrest table 200 will change and become tilted, which may cause the placed items to fall off the backrest table 200.

[0044] In particular, when the rear recline adjustment of the front seats is performed, the backrest table 200 may exert an impact on the body of the passenger sitting in the back, which may cause injury.

[0045] Therefore, the vehicle seat backrest table according to this embodiment includes a backrest table 200, a fixed switch 300, and a fixed guide 400, thereby solving the existing problems as described above.

[0046] The backrest table 200 is foldable or unfoldable and connected to the backrest panel 100 installed on the back of the seat back.

[0047] like Figure 2 As shown, this backrest table 200 can be equipped with a four-section linkage structure including an upper linkage 210 and a lower linkage 220, and one side and the other side of the upper linkage 210 and the lower linkage 220 are rotatably connected to the backrest panel 100 and the support guide 202, so that it can be folded or unfolded on the backrest panel 100 (see reference). Figure 3 ).

[0048] The fixed switch 300 can be installed on one side of the backrest table 200 and exposed externally (see reference). Figure 1b Furthermore, for the purpose of fixing the rotation angle of the backrest table 200, it can be slidably mounted on the backrest table 200 (see reference). Figure 6 and Figure 8 ).

[0049] In addition, when the fixed switch 300 slides forward in the operation groove H on one side of the backrest table 200, the switch wire 310 moves forward, thereby fixing the rotation angle of the backrest table 200. And when it slides backward in the operation groove H in the opposite direction, the switch wire 310 returns to the initial position, thereby releasing the fixing of the rotation angle of the backrest table 200.

[0050] like Figure 3 As shown, when the fixed switch 300 slides, the fixed guide 400 selectively engages with the fixed shaft 206 provided on the backrest table 200, more specifically, with the fixed shaft 206 that forms a hinge shaft for the rotation of the backrest table 200 and is fixedly connected to the rotating link 204, so as to guide the rotation angle of the fixed backrest table 200.

[0051] Here, as Figure 4 As shown, the fixed guide 400 includes a switch connector 410, a gear locking pin 420, a sliding gear 430, and an elastic member 440.

[0052] Since the fixed switch 300 includes a switch wire 310 having a predetermined length and extending therefrom, the switch connector 410 is connected to the fixed switch 300 via this switch wire 310.

[0053] The switch connector 410 is configured to move in the back-and-forth direction when the operating force of the sliding fixed switch 300 is transmitted through the switch line 310.

[0054] The gear locking pins 420 are formed such that a pair of gear locking pins are rotatably engaged around the rotation axis 410a of the switch connector 410, and when the switch connector 410 moves, they are in close contact with the fixed shaft 206, and each gear locking pin 420 rotates and unfolds in opposite directions around the rotation axis 410a.

[0055] More preferably, the gear locking pin 420 may be configured such that each edge region of its contact with the fixed shaft 206 in the initial position is rounded, thereby allowing it to rotate while in close contact with the fixed shaft 206 as described above (see reference). Figure 7 ).

[0056] The sliding gears 430 are configured such that a pair of sliding gears 430 are rotatably coupled to a rotation guide 206a extending from a fixed shaft 206, and when a pair of gear locking pins 420 are deployed, the sliding gears 430 are selectively movable on the fixed shaft 206 in a direction away from each other.

[0057] Here, each of the sliding gears 430 may have gear teeth on its outer side, and the fixed shaft 206 may be provided with a fixed gear 212, which has gear teeth on its inner side for selectively meshing with the sliding gears 430.

[0058] That is, the fixed gear 212 is fixedly mounted on the fixed shaft 206 and does not rotate. As the backrest table 200 rotates, the sliding gear 430 rotates along the rotation guide 206a. When the gear locking pin 420 is unfolded, the sliding gear 430 moves away from each other and selectively engages with the sliding gear 430. Here, as described above, since the fixed shaft 206 is fixed in a state of rotation, when the fixed gear 212 and the sliding gear 430 mounted on the rotating backrest table 200 engage with each other, the angle of the rotating backrest table 200 can be fixed.

[0059] The elastic member 440 provides an elastic force for moving the sliding gears 430 in a direction facing each other, such that when a pair of gear locking pins 420 are reset to their initial positions, the engagement between the sliding gears 430 and the fixed gears 212 is disengaged, thereby allowing the rotation of the backrest table 200 to be restored.

[0060] On the other hand, refer to Figures 5 to 8 The following will explain the fixing and unfixing of the rotation angle of the vehicle seat back table according to this embodiment, based on the structure of the fixed guide 400 described above.

[0061] like Figure 6 As shown, when the fixed switch 300 slides forward in the operating slot H, the switch line 310 connected to the fixed switch 300 will move forward.

[0062] Here, since switch line 310 is connected to switch connector 410, therefore, as Figure 5 As shown, when the operating force generated by the sliding of the fixed switch 300 is transmitted through the switch line 310, causing the switch connector 410 to move forward, a pair of gear locking pins 420 will also move forward and connect with the fixed shaft 206. At this time, when the switch connector 410 moves further forward, the pair of gear locking pins 420 rotate and unfold in opposite directions around the rotation shaft 410a.

[0063] As described above, when a pair of gear locking pins 420 are unfolded, the sliding gear 430 moves away from each other on the fixed shaft 206 by the amount that the pair of gear locking pins 420 are unfolded. At this time, when the sliding gear 430 moves and meshes with the fixed gear 212, the rotation angle of the backrest table 200, including the sliding gear 430, can be fixed because the backrest table 200 cannot rotate.

[0064] On the contrary, such as Figure 8 As shown, when the fixed switch 300 slides backward in the operating slot H, the switch line 310 connected to the fixed switch 300 will move backward.

[0065] Here, since switch line 310 is connected to switch connector 410, therefore, as Figure 7 As shown, when the operating force generated by the sliding of the fixed switch 300 is transmitted through the switch line 310, causing the switch connector 410 to move backward, a pair of gear locking pins 420 will also be released from their unfolded state and move backward.

[0066] At this time, when the unfolding of a pair of gear locking pins 420 is released, the sliding gear 430, which has moved away from each other through the elastic member 440, is reset to its initial position, thereby also releasing the meshing engagement between the sliding gear 430 and the fixed gear 212.

[0067] As described above, when the meshing between the sliding gear 430 and the fixed gear 212 is disengaged, the backrest table 200, including the sliding gear 430, can rotate, thus allowing the backrest table 200 to rotate freely in the folding or unfolding direction.

[0068] On the other hand, the vehicle seat back table according to this embodiment may further include an extension module 500, such as... Figure 1a and Figure 1b As shown, this lead-out module 500 is mounted on the backrest panel 100, allowing the backrest table 200 to be selectively unfolded.

[0069] Therefore, such as Figure 9 As shown, the lead-out module 500 may be equipped with an operation button 510 and a locking hook 520.

[0070] The operation button 510 is exposed on the surface of the backrest 100 and is configured to be elastically movable in the button housing 500a when pressed by the user.

[0071] Additionally, the latch 520 engages in the latching groove 200a of the backrest table 200 and is configured to be selectively rotated by moving the operation button 510 to disengage from the latching groove 200a.

[0072] In other words, the engaging hook 520 is bent to engage one side in the engaging groove 200a, and the other side is also bent from the central axis 520a and faces the operating button 510. Through this structure, as... Figure 10 As shown, when the operation button 510 moves elastically, when the other side of the engaging hook 520 is pressed and rotated with reference to the central axis 520a, one side of it rotates elastically to release the engagement from the engaging groove 200a.

[0073] Therefore, the backrest table 200, which is fixed to the backrest panel 100 in a folded state, can be converted into an easily unfolded state. At this time, as described above, when the fixed switch 300 is slid in the operation slot H, the rotation angle of the unfolded backrest table 200 can be fixed.

[0074] The advantage of this invention is that when the seat is extended and unfolded from the backrest, the sliding gear is selectively engaged with the fixed gear by operating the angle adjustment switch, thereby fixing the unfolded position.

[0075] Meanwhile, the advantage of this invention is that when the angle adjustment switch is operated in the fixed unfolded position of the seat back table, the sliding gear is reset to the initial position by the elastic component to disengage from the fixed gear, thereby easily converting the seat back table into a foldable or unfoldable state.

[0076] The present invention has been described above with reference to the embodiments shown in the accompanying drawings. However, these are merely examples, and those skilled in the art should understand that various modifications can be made therein, and all or part of the above embodiments can be selectively combined to form the invention. Therefore, the true scope of protection of the present invention should be defined by the technical concept of the appended claims.
