[0003] This specification discloses a small table on the back of a vehicle seat that is fixed to the seat back. Background Technology

[0004] The small tables fixed to the back of car seats, also known as seatback tables, have long been widely known. Most of these seatback tables function solely as small tables.

[0005] To further enhance occupant comfort, in addition to a small table, an auxiliary armrest that occupants can hold onto for support is also required. Patent Document 1 discloses a rod-shaped auxiliary armrest installed on the back of the front seat. In Patent Document 1, a speaker is installed at the end of this auxiliary armrest, thereby further improving occupant comfort.

[0006] However, the armrest in Patent Document 1 is rod-shaped, suitable for holding while seated in the rear. In other words, the armrest in Patent Document 1 is difficult for users to hold when getting on and off the vehicle. Furthermore, since the armrest in Patent Document 1 does not function as a small table, a separate table is required if needed. However, balancing space and cost makes it difficult to incorporate both the armrest and the small table. As a result, significantly improving passenger comfort is challenging in the prior art.

[0007] Therefore, this specification discloses a seat back table that can further improve the comfort of the occupants.

[0010] Patent Document 1: Japanese Patent Application Publication No. 2009-046001 Summary of the Invention

[0011] The seat back table disclosed in this specification is a seat back table installed on the back of a vehicle seat. It is characterized by comprising: a base plate fixed relative to the back of the seat back; a small table that can be opened and closed by swinging relative to the base plate, wherein at least a portion of the periphery of the base plate has a gap between it and the seat back, which is large enough to insert a fingertip, and the at least a portion of the periphery of the base plate functions as an armrest that can be held by a user.

[0012] By designing the structure in question, even in a cramped vehicle interior, the availability of both a small table and auxiliary armrests enhances passenger comfort. Furthermore, by utilizing the perimeter of the floor as an armrest, passengers can grip the floor from all directions. Thus, the auxiliary armrests are not limited to situations where passengers are seated in the rear seats; they can also be used when getting on or off the vehicle. As a result, passenger comfort is further improved.

[0013] In this case, the following method can also be adopted: the base plate is an arc-shaped rounded quadrilateral or a circle at the upper corner where the upper edge and the side edge intersect, and at least the upper edge, the side edge and the upper corner edge function as the armrest that can be held by the user.

[0014] By designing the structure in question, since there are no sharp corners on the armrests, occupants can grip the floor more comfortably.

[0015] Alternatively, a hinge with a latching function can be used to connect the small table to the base plate in a swingable manner and latch the opening angle of the small table relative to the base plate at a predetermined latching angle. The latching function can change the latching angle in multiple stages or continuously.

[0016] By designing the structure in question, the latching angle of the small table can be changed according to the tilt angle of the seat back. Furthermore, this ensures that the small table remains horizontal even if the tilt angle of the seat back changes.

[0017] In this case, the latching angle of the hinge with latching function can be varied to a greater extent than the reclining angle of the seat back.

[0018] By setting the structure in question, the small table can remain level even if the reclining angle of the seat back is significantly changed.

[0019] Alternatively, a connector may be provided that can be attached to and detached from the base plate, and the connector supports the object by being mounted on the base plate.

[0020] By setting the structure in question, the convenience of the small table on the back of the chair can be further improved.

[0021] In this case, the following method can also be adopted: on the opposing surface of the base plate opposite to the small table, a recessed portion is formed in the thickness direction and the connector is installed thereon, the recessed portion having a size that can completely accommodate the connector.

[0022] By configuring the structure in question, the small table can be closed even with the connector installed. Furthermore, this reduces the number of times the connector needs to be disassembled and reassembled, thereby reducing the workload for the occupants.

[0023] Alternatively, the base plate may have a guide rail groove that is elongated in the left-right direction and is located at the part exposed when the small table is open, and the connector is attached to any position of the guide rail groove.

[0024] By setting the structure involved, the left and right positions of the connector can be freely changed.

[0025] Furthermore, it can also be further provided with a latch that keeps the small table in a closed state. The latch is a magnetic latch, which has a magnet disposed on one of the base plate and the small table, and a magnetic body or another magnet disposed on the other of the base plate and the small table and magnetically attracted to the magnet.

[0026] By designing the structure in question, the locking mechanism can be released simply by grasping the perimeter of the tray table and pulling it towards the front. In other words, since no complicated operation is required to unlock the tray table, occupants can open it intuitively.

[0027] Alternatively, it can also be provided with a fixing part that protrudes from the base plate toward the seat back and is fixedly mounted on the back of the seat back, with a recess formed on the upper surface of the fixing part.

[0028] By designing the structure in question, small items can be placed in the recess on the upper surface of the mounting section. Furthermore, since the seat back is located directly in front of the mounting section, thin, flat components such as smartphones placed in the recess can rest against the seat back. Moreover, this further enhances the convenience of the seat back table.

[0029] The seat back table disclosed in this specification can further improve the comfort of the occupants. Attached Figure Description

[0043] The structure of the small table 10 on the back of the chair will be described below with reference to the attached drawings. Figure 1 A 3D view of the seat back table 10 in its closed state. Figure 2 A perspective view of the small table 10 on the back of the chair in its open position. Additionally, Figure 3 This is a rear view of the small table 10 on the back of the chair. Figure 4 From Figure 3The diagram shows the small table 14 that was removed from the middle. Furthermore, Figure 5 for Figure 3 A sectional view of section AA. Furthermore, unless otherwise specified, the terms "front," "front-back," "left-right," "up," and "down" in the following description refer to the directions viewed from the perspective of an occupant seated on the vehicle seat 100. Additionally, the terms "Fr," "Rh," and "Up" in the accompanying drawings refer to the directions viewed from the perspective of an occupant seated on the vehicle seat 100: front, right side, and above, respectively.

[0044] The seatback table 10 is a small table fixed to the seatback 110 of the vehicle seat 100 installed in the vehicle. The seatback table 10 is primarily for use by rear occupants (hereinafter referred to as "users") seated in the rear seats (not shown) located behind the vehicle seat 100. Furthermore, while the vehicle seat 100 and the rear seats are not specifically limited to any seats installed in a vehicle, for example, the vehicle seat 100 can be the driver's seat or the front passenger seat, and the rear seats can be the rear seats of the vehicle.

[0045] The seat back table 10 is roughly divided into a base plate 12, a mounting part 16 that fixes the base plate 12 to the seat back 110, and a small table 14 that can swing relative to the base plate 12. The seat back table 10 can be transformed into... Figure 1 , Figure 3 , Figure 5 The "off state" and Figure 2 The "open state" is shown. In the closed state, the small table 14 is approximately parallel to the base plate 12 and overlaps with the base plate 12 in the thickness direction. In the open state, the small table 14 is approximately parallel to the horizontal direction and forms a predetermined angle with respect to the base plate 12. In the open state, various items can be placed on the upward-facing surface of the small table 14 (hereinafter referred to as "small tabletop 52"). Therefore, in the open state, the user can use the small table 14 as a small table.

[0046] Furthermore, the seat backrest table 10 in this example also functions as an auxiliary armrest for the user to hold onto for support. When used as an auxiliary armrest, the user can grasp the perimeter of the seat backrest table 10 with their hands. The structure of each part of the seat backrest table 10 will be described below.

[0047] The base plate 12 is a plate-shaped component fixed in an attitude substantially parallel to the back of the seat back 110. The base plate 12 is spaced apart from the back of the seat back 110 by a gap G1 (see reference). Figure 5The base plate 12 is located behind the seat back 110 in a manner that allows it to be positioned. The base plate 12 is a rounded rectangle formed by connecting the upper edge and the side edges with a gentle arc. In other words, the base plate 12 has a rounded shape without sharp corners.

[0048] like Figure 2 , Figure 4 , Figure 5 As shown, a recessed storage portion 24, recessed in the thickness direction, is formed on the central portion of the back side of the base plate 12 (i.e., the side facing the small tabletop 14). Within this storage recess 24, two elongated guide grooves 26 are provided, spaced vertically. A connector 60, described later, is installed in these guide grooves 26. While the storage recess 24 is large enough to completely accommodate the connector 60, this will be described later.

[0049] A magnet 42, which is a component of the magnetic latch 40, is provided on the upper side relative to the receiving recess 24. This magnet 42 maintains the small table 14 in a closed state through the magnetic attraction between itself and the magnetic body 44 mounted on the small table 14. A hinge 28, which supports the small table 14 in a swinging manner, is provided on the lower part of the base plate 12. The structure of this hinge 28 will be described in detail later.

[0050] like Figure 1 , Figure 2 , Figure 5 As shown, the mounting portion 16 protrudes from the front surface of the base plate 12 (i.e., the side opposite to the small table 14). The mounting portion 16 is a part that is fixedly mounted on the back of the seat back 110. The method by which the mounting portion 16 is fixed to the seat back 110 is not particularly limited. Therefore, the mounting portion 16 can be fixed using fastening components such as bolts or adhesives. Regardless of the method used, the mounting portion 16 is firmly fixed to the seat back 110 and will not loosen even if the user pulls on it. In this example, the mounting portion 16 is integrally formed with the base plate 12. However, it is obvious that the mounting portion 16 can also be a separate part from the base plate 12.

[0051] exist Figure 4 The outline of the fixed mounting part 16 is shown in the figure with dashed lines. As per the diagram... Figure 4As explicitly stated, the outer shape of the mounting portion 16 is smaller than that of the base plate 12. Specifically, the upper edge of the mounting portion 16 is a few centimeters lower than the upper edge of the base plate 12, and the side edges of the mounting portion 16 are a few centimeters inward in the left-right direction compared to the side edges of the base plate 12. Furthermore, the thickness (i.e., the front-back dimension) of the mounting portion 16 is sufficiently large compared to the thickness of a user's hand. As a result, a gap G1 equivalent to the thickness of the mounting portion 16 is created between the periphery of the base plate 12, especially its upper edge, side edges, and upper corner edges, and the seat back 110 (see reference). Figure 5 The gap G1 is large enough to allow a user's fingertips to be inserted. Furthermore, by having the gap G1, the user can grip the upper edge, side edges, and upper corner edges of the base plate 12. In other words, the upper edge, side edges, and upper corner edges of the base plate 12 function as armrests 32 that can be held by the user's hands. Figure 4 The thick lines in the text indicate the perimeter range that functions as the armrest part 32. Figure 5 As shown, the periphery of the base plate 12 and even the cross-sectional shape of the armrest 32 have a generally semi-circular thickness that is easy to grip by hand.

[0052] Furthermore, as according to Figure 4 As clearly stated, the upper surface of the mounting portion 16 is provided with an upper surface recess 30 that is recessed downwards compared to the surrounding area. The user can use this upper surface recess 30 as a small item holder for placing small items such as pills.

[0053] The small table 14 is a plate-shaped component with a shape roughly the same as the base plate 12. The surface of the small table 14 that faces the base plate 12 in the closed state, i.e., the small tabletop 52, is mostly a flat surface without any bumps or depressions. In the open state, this small tabletop 52 is roughly parallel to the horizontal direction, allowing for the placement of various items.

[0054] A magnetic body 44, which is a component of the magnetic latch 40, is provided in the small tabletop 52 at a position directly opposite the magnet 42 when the tabletop is closed. Furthermore, when the small tabletop 14 is closed and locked, the magnetic body 44 and the magnet 42 attract each other through magnetic force, thereby maintaining the closed state. It is also apparent that the magnet 42 and the magnetic body 44 can be arranged in reverse; the magnetic body 44 can be provided on the base plate 12, and the magnet 42 on the small tabletop 14. Alternatively, the magnet 42 can be provided on both the base plate 12 and the small tabletop 14.

[0055] The perimeter of the small table 14 is decorated with a metallic style. Figure 3In the image, the areas shaded with gray indicate decorative parts 50 that have been given a metallic finish. For example... Figure 5 As shown, the periphery of the small table 14, i.e., the decorative part 50, has a circular cross-section, and a small gap G2 is formed between it and the base plate 12. The user can release the magnetic latch 40 by hooking their fingertip into the gap G2 and pulling it towards the front.

[0056] Here, as clearly stated in the preceding description, in this example, the upper edge, side edges, and upper corner edges of the base plate 12 function as armrests 32 for the user to grip. In other words, in this example, the seat back table 10 not only functions as a small table but also as an auxiliary armrest. Furthermore, by configuring the structure described, both a small table and an auxiliary armrest can be provided within the confined space of the vehicle, thereby further enhancing user convenience.

[0057] Furthermore, according to this example, the user can grasp the floor panel 12 from various directions, thus utilizing the armrest 32 in a wide range of scenarios. For example, when getting on or off the vehicle, the user can grasp the upper corner edge or side edge of the floor panel 12 from the side, thereby making getting on and off the vehicle safer. In addition, when the user is sitting in the rear seat, they can grasp the upper edge of the floor panel 12 from above, thereby suppressing body swaying and further improving the comfort inside the vehicle.

[0058] Additionally, when the small table 10 on the back of the seat is closed, such as Figure 5 As shown, the user will grasp the base plate 12 and the small table 14 together. Furthermore, when the small table 10 on the seat back is in the open position, as... Figure 6B As shown, the user only grips the base plate 12. Therefore, the base plate 12 and the small table 14 are of a suitable thickness for gripping, regardless of whether they are in the open or closed state. Furthermore, the periphery of the base plate 12 and the small table 14 has a rounded cross-section with rounded corners so that no sharp corners will come into contact with the hand when gripping.

[0059] Furthermore, the gap G1 between the periphery of the base plate 12 and the seat back 110 can also be utilized as space for placing various small items. For example, as described above, in this example, an upper surface recess 30 is formed on the upper surface of the fixed mounting portion 16. Small items can be placed in this upper surface recess 30. Furthermore, the seat back 110 is located immediately in front of the upper surface recess 30. Therefore, as... Figure 6AAs shown, a plate-shaped item 130, such as a smartphone or tablet, can be placed in the upper surface recess 30 by resting it against the seat back 110. Alternatively, a rod-shaped item, such as an umbrella or cane, can be inserted from the side into the gap between the side edge of the base plate 12 and the seat back 110, resting against the side of the mounting portion 16. In this case, tipping over is effectively prevented, thus keeping the rod-shaped item stable and upright. Furthermore, clothing such as jackets or short coats can be hung around the perimeter of the base plate 12.

[0060] Furthermore, as described above, the small table 14 is able to swing relative to the base plate 12 via a hinge 28. This hinge 28 has a latching function that maintains the opening angle of the small table 14 relative to the base plate 12 at a predetermined latching angle. Moreover, the latching angle can be changed in multiple stages or continuously. For example, a ratchet hinge that can switch the latching angle in multiple stages, or a torque hinge that can continuously change the latching angle, can be used as the hinge 28.

[0061] Reference Figure 6A , Figure 6B This explains the rationale for using hinge 28, which allows for changing the opening angle θo (i.e., latch angle) when the latch is engaged. As repeatedly stated, the seat back table 10 in this example is fixed to the seat back 110. Then, generally speaking, the angle between the back of the seat back 110 and the vertical direction (hereinafter referred to as the "backward tilt angle θb") can be freely changed within a fixed range. Therefore, when the latch angle is set to a fixed value, depending on the backward tilt angle θb of the seat back 110, the table 14 may not be able to remain horizontal, and thus items cannot be placed stably.

[0062] On the other hand, in this example, as described above, the latch angle can be changed in stages or continuously. By configuring the structure in question, the opening angle θo of the small table 14 can be changed in conjunction with the change in the reclining angle θb of the seat back 110. For example, by using a method similar to... Figure 6A As shown, when the back tilt angle θb is small, the opening angle θo is increased, like... Figure 6B As shown, when the backward tilt angle θb is large, the opening angle θo is reduced, thereby enabling the small table 14 to remain horizontal.

[0063] Furthermore, in this case, the adjustable range of the latching angle of the hinge 28 is greater than the adjustable range of the reclining angle of the seat back 110. For example, if the reclining angle of the seat back 110 can be varied within the range of θb1 to θb2, the latching angle of the hinge 28 can be varied within the range of at least (90-θb1+α) to (90-θb2+α). Additionally, the angle α is a fixed value and is the angle formed by the back of the seat back 110 and the base plate 12.

[0064] Furthermore, as mentioned above, in this example, a magnetic latch 40 is used to keep the small table 14 in the closed state. By adopting this structure, opening and closing the small table 14 becomes easier, thereby improving the convenience of the seat back table 10. That is, as a latching mechanism, a locking mechanism that engages a claw formed on one side with a hole formed on the other side, or a locking mechanism that engages a locking member formed on one side with a part of the other side, can be widely used. However, such locking or engaging latching mechanisms require specific operations at specific locations to release the latch. For example, in the case of a locking mechanism, a part of the claw needs to be pressed with a finger each time the latch is released. Furthermore, in a locking mechanism, releasing the latch requires operating a specific component such as a handle to move the locking member in the direction of disengagement.

[0065] On the other hand, with the magnetic latch 40, if the small table 14 is pulled in the opening direction with a force greater than magnetic attraction, the latch will be released. In this case, the position where the pulling operation is performed is not particularly limited. In this example, a gap G2 is formed between the decorative part 50 formed on the periphery of the small table 14 and the base plate 12, which can be hooked by a fingertip. If the fingertip hooks into the gap G2 and is pulled, the latch can be released, thereby opening the small table 14. That is, by using the magnetic latch 40, the periphery of the small table 14, especially the upper edge, side edges, and upper corner edges, can function as opening operation parts for receiving the opening operation of the small table 14. Then, by using most of the periphery of the small table 14 as opening operation parts in this way, the user can open the small table 14 more intuitively, thus improving the convenience of the seat back table 10. In addition, although the magnetic latch 40 is used in this example, it is obvious that other latching mechanisms can also be used. For example, a latching mechanism using hook and loop fasteners, a latching mechanism using pawls, or a snap-fit ​​latching mechanism can also be used.

[0066] Next, the connector 60, which is mounted on the base plate 12, will be described. Figure 7 A rear view of the seat back table 10 with the arm-type connector 62 installed. Furthermore, Figure 8 , Figure 9 This is a perspective view showing an example of the connector 60. As described above, the connector 60 can be mounted on the base plate 12. Although the manner in which the connector 60 is mounted is not particularly limited, for example... Figure 8 The arm-type connector 62 shown, or Figure 9 The bag-type connector 64 is shown. (As shown) Figure 8 As shown, the arm-type connector 62 has a base 66 and an arm 68. The arm 68 is a rod-shaped member that is elongated in one direction and has a slightly curved tip. Furthermore, the base of the arm 68 is connected to the base 66 in a swinging manner. The swing angle of the arm 68 can be latched in stages. Moreover, by latching the swing angle of the arm 68 at various angles, it is possible to hold articles of various shapes.

[0067] For example, such as Figure 7 Like the arm-type connector 62a, if the arm 68 is set at an angle approximately parallel to the base 66, thin sheet components such as smartphones can be clamped between the arm 68 and the base plate 12. Alternatively, it can be like... Figure 7 Like the arm-type connector 62b, the arm 68 is latched at an angle that is approximately orthogonal to the base 66. In this case, if the two arm-type connectors 62b are combined, it is possible to clamp thick items such as cups through the two arms 68.

[0068] In addition, although Figure 7 , Figure 8 While not visible in the center, a connecting member 70 is provided on the inner side of the base 66, which is inserted into and engaged with the guide rail groove 26. The connecting member 70 is not particularly limited as long as it can be installed and removed from the guide rail groove 26. Therefore, for example, the connecting member 70 could be as follows: Figure 10A As shown, an elastic protrusion 70a protrudes from the back of the base 66 and is made of an elastic material such as rubber. In this case, the vertical dimension near the entrance of the guide groove 26 is smaller than the vertical dimension of the elastic protrusion 70a. Moreover, the connector 60 is engaged with the base plate 12 by pressing the elastic protrusion 70a into the guide groove 26. Alternatively, the engaging member 70 may also be configured as follows: Figure 10BAs shown, a roughly L-shaped hook 70b extends downward after protruding horizontally from the base 66. In this case, the guide groove 26 has a roughly L-shaped cross-section larger than that of the hook 70b. By inserting the hook 70b into the guide groove 26 and engaging it, the connector 60 is joined to the base plate 12. In any case, the left-right position of the connector 60 can be freely adjusted by employing a structure in which the connecting member 70 of the connector 60 engages with the guide groove 26, which is elongated in the left-right direction. Furthermore, it is obvious that the shapes of the connecting member 70 and the guide groove 26 are not limited to these cases and can be appropriately modified. For example, although the connector 60 is mounted using the guide groove 26 in this example, the connector 60 can also be mounted without utilizing the guide groove 26. For example, the connector 60 can also be mounted on the base plate 12 using a magnet.

[0069] In addition, it is also possible to use, such as Figure 9 The bag-type connector 64 is shown. The bag-type connector 64 has a base 66 that overlaps along the surface of the receiving recess 24, and a bag portion 67 extending from the base 66. On the back side of the base 66, a shape resembling... Figure 10A or Figure 10B The connecting component 70 is shown as described. By utilizing the pocket-shaped connector 64 involved, smaller items, such as keys or rings, can be stably stored. Furthermore, the structure of the connector 60 described so far is only an example, and various shapes of connectors 60 can be set up to accommodate items that are desired to be held.

[0070] Furthermore, in this example, the recess 24 is designed to fully accommodate the connector 60. This configuration allows the small table 14 to be closed while the connector 60 remains mounted on the base plate 12. As a result, the number of times the connector 60 needs to be disassembled and reassembled is reduced, thereby improving the convenience of the seat back table 10.

[0071] In addition, such as Figure 11As shown, a mirror 76 can also be installed in the receiving recess 24 of the base plate 12 instead of the guide rail groove 26. In this case, the angle of the mirror 76 can be freely changed. For example, the upper end of the mirror 76 can be connected to the receiving recess 24 in a swingable manner, and the cover 78 covering the mirror 76 can be connected to the lower end of the mirror 76 in a swingable manner. Furthermore, a connecting member 79 is pre-installed at the end of the cover 78 opposite to the connecting part (i.e., the free end) to engage with any position on the small tabletop 52. In this case, by pulling the free end of the cover 78 towards the front, the lower end of the mirror 76 is pulled forward, thereby allowing the angle of the mirror 76 to be freely changed. By adjusting the mirror 76 to the desired angle, the connecting member 79 at the free end of the cover 78 can be engaged with the small tabletop 52. Furthermore, while the structure of the connecting component 79 is not particularly limited, it can be, for example, a high-friction component that generates high friction with the small tabletop 52. Additionally, if the small tabletop 52 has a magnetic material, the connecting component 79 can also be a magnet. In any case, by providing the mirror 76 on the base plate 12, the user can easily perform tasks such as applying makeup inside the vehicle.

[0072] Furthermore, the structures described so far are merely examples. Any structure that includes a base plate 12 fixed to the back of the seat back 110, a small table 14 that opens and closes by swinging relative to the base plate 12, and at least a portion of the periphery of the base plate 12 functions as an armrest 32, is acceptable. Other structures can be appropriately modified. For example, the shapes of the base plate 12 and the small table 14 can be appropriately modified; for instance, instead of rounded quadrilaterals, they can be designed as... Figure 4 The circular shape R is shown with a double-dotted line. Alternatively, it may not have the receiving recess 24 or the upper surface recess 30.
