Summary of the Invention

Problems to be Solved by the Invention

[0005] For example, the tray for storing luggage as in Patent Document 1 is provided at the front end of the seat cushion when in the stored state, so the space below the seat cushion could not be effectively utilized. Also, when a cover storage member as in Patent Document 2 is provided at the front end of the seat cushion, there is a possibility that it may be obstructive when the cover is not in use.

[0006] An object of the present invention is to provide a vehicle seat capable of effectively utilizing the space below the seat cushion. Another object of the present invention is to provide a vehicle seat capable of storing a cover storage member in the space below the seat cushion.

Means for Solving the Problems

[0007] According to the vehicle seat of the present invention, the above problems are solved by a vehicle seat including a seat back that supports the back of an occupant and a seat cushion that supports the buttocks of the occupant, wherein a storage portion that is disposed below the seat cushion and capable of storing articles, and a rotating member that is rotatably attached to the seat cushion, connects the seat cushion and the storage portion, and moves the storage portion with respect to the seat cushion, and the storage portion moves between a normal position where it is disposed below the front portion of the seat cushion and a storage position where it is located behind the normal position and is stored below the seat cushion when the rotating member rotates with respect to the seat cushion. With the above configuration, the storage portion can be pulled backward by the rotating member and moved below the seat cushion. Therefore, the space below the seat cushion can be effectively utilized.

[0008] At this time, the rotating member includes a first link rotatably attached to the seat cushion, a second link attached to the storage portion, a connection link connecting the first link and the second link and rotatably attached to the first link and the second link, and a moving portion attached to the connection link and moving the connection link rearward with respect to the seat cushion. As the moving portion moves the connection link rearward, the second link moves rearward with respect to the seat cushion, and thus the storage portion may move rearward from the normal position toward the storage position. With the above configuration, since the storage portion can be pulled rearward by the rotation of each link member, the storage portion can be moved rearward with a simple configuration.

[0009] At this time, the vehicle seat has a switching member that switches between a use state in which the seat back and the seat cushion can be seated by the occupant and a folded state in which the seat back is folded so as to overlap the seat cushion from the use state and the seat back and the seat cushion are stored in the vehicle floor. In response to the operation of the switching member for switching the seat back and the seat cushion from the use state to the folded state, the moving portion may move the connection link rearward with respect to the seat cushion. With the above configuration, the storage portion can be pulled rearward in conjunction with the operation of storing the seat cushion in the floor. Therefore, even when the seat cushion is stored, the storage portion can be pulled into a position where it does not get in the way.

[0010] At this time, the switching member is rotatably attached to the front end portion of a cushion frame that forms the framework of the seat cushion, and has an arm portion extending toward the floor and a support portion disposed on the floor and rotatably supporting the arm portion with respect to the floor. The moving portion connects the cushion frame and the connection link, and has a curved connection link rotatably attached to the cushion frame and the connection link. Corresponding to the operation in which the support portion rotates the arm portion to switch the seat back and the seat cushion from the use state to the folded state, the connection link may move the connection link rearward with respect to the seat cushion. With the above configuration, the connecting link can pull the storage portion rearward in conjunction with the operation of storing the seat cushion in the floor with a simple configuration.

[0011] At this time, the switching member is rotatably attached to the front end portion of a cushion frame that forms the framework of the seat cushion, and has an arm portion extending toward the floor and a support portion disposed on the floor and rotatably supporting the arm portion with respect to the floor. The moving portion is attached to the rotation axis of the first link, the connection link, or the second link, and has a biasing member that biases the connection link rearward. Corresponding to the operation in which the support portion rotates the arm portion to switch the seat back and the seat cushion from the use state to the folded state, the biasing member may move the connection link rearward with respect to the seat cushion. With the above configuration, the biasing member can pull the storage portion rearward in conjunction with the operation of storing the seat cushion in the floor with a simple configuration.

[0012] At this time, a fixing portion for fixing the storage portion to the normal position is provided at the front portion of the seat cushion. The storage portion is locked to the fixing portion when in the normal position and fixed below the front portion of the seat cushion, and may be stored below the seat cushion in a state where the locking with the fixing portion is released when in the storage position. With the above configuration, by fixing the storage portion with the fixing portion, the storage portion can be held at a suitable position in the normal position.

[0013] At this time, an opening for storing the article may be formed at the front end portion of the storage portion, and the storage portion may be locked to the fixing portion so that the orientation of the opening can be adjusted when in the normal position. With the above configuration, since the orientation of the opening can be adjusted, it becomes easier to take out the article stored in the storage portion.

[0014] At this time, a recess for storing the storage portion may be formed on the lower surface of the seat cushion, and the storage portion may be stored in the recess when in the storage position. With the above configuration, it can be suitably stored even when the seat cushion is stored on the floor.

[0015] At this time, a cover for covering the seat back, the seat cushion, or the floor of the vehicle may be stored in the storage portion. With the above configuration, since the cover can be stored in the space below the seat cushion, it can be stored in a position where it does not get in the way when not in use.

[0016] At this time, an opening for storing the cover may be formed at the front end portion of the storage portion, and a fastener for opening and closing the opening may be provided at the opening. With the above configuration, since the opening can be easily closed with the fastener, the cover can be suitably stored below the seat cushion.

[0017] At this time, it is preferable that the storage section stores the cover and a winding section that winds up the cover. With the above configuration, by winding up and storing the cover, the storage space can be further reduced.

[0018] At this time, a cover that covers the floor of the vehicle is stored in the storage section, and the cover is fixed at a position covering the floor by a cover fixing section provided on an interior component arranged in front of the vehicle seat or a cover fixing section provided on the floor. With the above configuration, the cover can be fixed at a suitable position even when the floor is covered with the cover.

Mode for Carrying Out the Invention

[0021] Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 13. In the following description, the "front-rear direction" refers to the front-rear direction of the vehicle seat, which is the same as the traveling direction of the vehicle when it is moving. Also, the "seat width direction" refers to the width direction of the vehicle seat, which is the same as the left-right direction as seen by the occupant sitting on the vehicle seat. Further, the "up-down direction" refers to the up-down direction of the vehicle, which is the same as the vertical direction when the vehicle is traveling on a horizontal plane.

[0022] <First Embodiment> As shown in FIG. 1, the vehicle seat S of the present embodiment is a seat placed on the floor F of the vehicle and on which the vehicle occupant sits. The vehicle seat S is used as a rear seat corresponding to the rear seat of the vehicle. However, it is not limited thereto, and the vehicle seat S may be a front seat of the vehicle, and can also be used as a middle seat in the second row or a rear seat in the third row in a vehicle equipped with three rows of seats in the front-rear direction.

[0023] As shown in FIG. 1, the vehicle seat S includes a seat back 1 that supports the occupant's back and a seat cushion 2 that supports the occupant's buttocks. The seat back 1 is a backrest that supports the occupant from behind, and a seat frame (back frame 1a) serving as a skeleton is provided inside thereof. The seat cushion 2 is a seating portion that supports the occupant from below, and a seat frame (cushion frame 2a) serving as a skeleton is provided inside thereof.

[0024] As shown in FIG. 1, the vehicle seat S includes a seat body having the seat back 1 and the seat cushion 2, a switching member 3 that switches the seat body between a use state and a folded state to be described later, a storage portion 4 disposed below the seat cushion 2 and capable of storing articles, a rotating member 5 rotatably attached to the seat cushion 2, and a fixing portion 6 that fixes the storage portion 4 in a normal position. FIG. 2 is a view of the left side portion of the vehicle seat S as seen from the front, and is a view for explaining the positional relationship among the seat cushion 2, the switching member 3, the storage portion 4, and the rotating member 5. In FIG. 2, a part of the switching member 3 is omitted. The storage portion 4 and the rotating member 5 are provided on the inner side in the seat width direction from the switching member 3 below the seat cushion 2. The rotating member 5 connects the seat cushion 2 and the storage portion 4 via the switching member 3 and moves the storage portion 4 with respect to the seat cushion 2.

[0025] As shown in FIGS. 3 and 4, the vehicle seat S can be switched between a use state and a folded state by the switching member 3. The use state is a state in which an occupant can be seated, as shown in FIG. 3, and is a state in which the seat back 1 is in an upright position. The folded state is a so-called dive-down state, as shown in FIG. 4, in which the seat back 1 is folded so as to overlap the seat cushion 2 from the use state, and the seat back 1 and the seat cushion 2 are stored in the vehicle floor F.

[0026] <Switching member> As shown in FIG. 1, the switching member 3 includes a first arm portion 10 rotatably attached to the front portion of the cushion frame 2a, a first support portion 11 that rotatably supports the first arm portion 10 with respect to the floor F, a second arm portion 12 rotatably attached to the first arm portion 10, a third arm portion 13 rotatably attached to the rear end portion of the second arm portion 12, a fourth arm portion 14 rotatably attached to the lower end portion of the third arm portion 13, and a second support portion 15 that rotatably supports the fourth arm portion 14 with respect to the floor F.

[0027] The switching member 3 is composed of a plurality of arms, and each arm is rotatably connected to each other. More specifically, as shown in FIGS. 2 and 3, the switching member 3 has a first shaft 3a, a second shaft 3b, a third shaft 3c, a fourth shaft 3d, and a fifth shaft 3e. The first shaft 3a pivotally connects the lower end of the first arm portion 10 to the first support portion 11. The second shaft 3b pivotally connects the upper end of the first arm portion 10 and the front end of the second arm portion 12 to each other. The third shaft 3c pivotally connects the rear end of the second arm portion 12 and the upper end of the third arm portion 13 to each other. The fourth shaft 3d pivotally connects the lower end of the third arm portion 13 and the rear end of the fourth arm portion 14 to each other. The fifth shaft 3e pivotally connects the front end of the fourth arm portion 14 to the second support portion 15. In addition, an urging mechanism (such as a torsion spring) for assisting the operation of switching the seat body between the use state and the folded state may be provided on each rotation shaft of the switching member 3.

[0028] The first arm portion 10 is a long member extending toward the floor F, and is pivotally attached to the front portion of the cushion frame 2a forming the skeleton of the seat cushion 2. The upper end portion of the first arm portion 10 is pivotally supported by the cushion frame 2a via the second shaft 3b. The lower end portion of the first arm portion 10 is pivotally supported by the first support portion 11 via the first shaft 3a.

[0029] The first support portion 11 is disposed on the floor F and pivotally supports the first arm portion 10 with respect to the floor F. In other words, the first arm portion 10 is rotated about the first shaft 3a by the first support portion 11 fixed to the floor F.

[0030] The second arm portion 12 is a long member extending in the front-rear direction, and is pivotally attached to the upper end portion of the first arm portion 10. The front end portion of the second arm portion 12 is pivotally attached to the front portion of the cushion frame 2a via the second shaft 3b together with the upper end portion of the first arm portion 10. The rear end portion of the second arm portion 12 is pivotally attached to the lower portion of the back frame 1a via the third shaft 3c.

[0031] The third arm portion 13 is an elongated member extending toward the floor F, and is rotatably attached to a lower portion of the back frame 1a that forms the skeleton of the seat back 1. The upper end portion of the third arm portion 13 is rotatably attached to the lower portion of the back frame 1a via a third shaft 3c together with the rear end portion of the second arm portion 12. The lower end portion of the third arm portion 13 is rotatably attached to the rear end portion of the fourth arm portion 14 via a fourth shaft 3d.

[0032] The fourth arm portion 14 is a member having a substantially T-shaped elongated shape in the front-rear direction, and is rotatably attached to the lower end portion of the third arm portion 13 via a fourth shaft 3d. The front end portion of the fourth arm portion 14 is rotatably attached to the second support portion 15 via a fifth shaft 3e. An engaging portion 14a that engages with a striker St fixed to the floor F is provided at a central portion of the fourth arm portion 14 in the front-rear direction.

[0033] The engaging portion 14a is, for example, a latch device that detachably engages with the striker St, and is supported by the floor F by engaging with the striker St when the seat body is in a normal state. In a state where the engaging portion 14a engages with the striker St, the fourth arm portion 14 is locked to the floor F. When the engagement between the engaging portion 14a and the striker St is released, the lock is disengaged and the fourth arm portion 14 becomes rotatable about the fifth shaft 3e with respect to the floor F.

[0034] The second support portion 15 is disposed on the floor F and rotatably supports the fourth arm portion 14 with respect to the floor F. In other words, the fourth arm portion 14 is rotated about the fifth shaft 3e by the second support portion 15 fixed to the floor F.

[0035] When switching the state of the vehicle seat S from the normal state to the folded state, the occupant tilts the seat back 1 forward from the normal state shown in FIG. 3. As shown in FIG. 4, the seat back 1 rotates about the third shaft 3c together with the third arm portion 13. When the third arm portion 13 rotates forward, the second arm portion 12 is pushed forward by the third arm portion 13, and the first arm portion 10 rotates forward about the first shaft 3a. Then, the seat cushion 2 moves downward toward the front, and the lower surface of the seat cushion 2 abuts against the floor F. Also, the seat back 1 is folded so as to overlap the seat cushion 2 in the vertical direction and is supported by the seat cushion 2.

[0036] In this way, the switching member 3 can switch the seat body between the use state and the folded state. Note that the seat body of the vehicle seat S may be configured to be switchable to a hip-up state in which the rear end portion of the seat cushion 2 is located above the front end portion, as compared with the normal state. When switching the state of the vehicle seat S from the normal state shown in FIG. 3 to the hip-up state, the occupant operates an operation lever (not shown) to release the engagement between the engaging portion 14a and the striker St. Thereafter, the occupant lifts the rear end portion of the seat cushion 2 together with the seat back 1 and moves the seat body forward. When the fourth arm portion 14 abuts against the rear surface 15a of the second support portion 15 and the front end portion of the seat cushion 2 abuts against the floor F, the seat body is held in the hip-up state.

[0037] <Storage portion> As shown in FIGS. 1 and 2, the storage portion 4 is a container disposed below the seat cushion 2 and having a space capable of storing articles. More specifically, the storage portion 4 includes a storage main body portion 4a having a rectangular shape, a cover 4b for covering the seat body and the floor F, a winding portion 4c for winding the cover 4b, and a fastener 4d capable of opening and closing the opening 4a1 of the storage main body portion 4a. In this embodiment, the cover 4b that covers the seat back 1, the seat cushion 2, or the floor F of the vehicle is stored in the storage portion 4, but the articles to be stored are not limited to this.

[0038] The storage main body portion 4a is a box having a space for storing articles inside. Note that a tray capable of storing articles may also be used. An opening 4a1 for storing articles is formed at the front end portion of the storage main body portion 4a. A fastener 4d is provided at the opening 4a1. Inside the storage main body 4a, a cover 4b and a winding part 4c are stored. At the rear end of the storage main body 4a, a second link 21 (described later) is rotatably connected. Also, as shown in FIG. 3, at the normal position, a locking part 6b of a fixing part 6 (described later) is locked to the upper surface of the storage main body 4a.

[0039] The cover 4b is, for example, a waterproof cover that is long in the front-rear direction and is wound around the winding part 4c during storage. The cover 4b is pulled out from the opening 4a1 and is arranged to cover the seat body or the floor F. Note that a handle for pulling out the cover 4b may be provided at the front end of the cover 4b.

[0040] The winding part 4c is a long rod-shaped member that extends in the seat width direction and is stored inside the storage main body 4a. When the cover 4b is stored, the winding part 4c is rotated by an operation member (not shown), and the pulled-out cover 4b is wound around the winding part 4c and stored inside the storage main body 4a.

[0041] The fastener 4d is, for example, a wire fastener that is long in the seat width direction and is attached to the storage main body 4a. When the cover 4b is stored, the opening 4a1 is closed by the fastener 4d. When the cover 4b is used, the opening 4a1 is opened by the fastener 4d, and it can be pulled out from the storage main body 4a. Note that the fastener 4d is not limited to a wire fastener and may be a surface fastener. Also, the opening 4a1 may be closed by a locking tool such as a button or a hook, and the fastener 4d or the locking tool may not be provided.

[0042] The storage part 4 moves between a normal position (FIG. 3) where it is arranged below the front part of the seat cushion 2 and a storage position (FIG. 4) where it is behind the normal position and is stored below the seat cushion 2 when the rotating member 5 rotates with respect to the seat cushion 2. As shown in FIGS. 3 and 4, the storage part 4 moves from the normal position to the storage position in response to the operation of the switching member 3 for switching the seat body from the use state to the folded state. In other words, when the seat body is in the use state, the storage part 4 is in the normal position. Also, when the seat body is in the folded state, the storage part 4 is in the storage position.

[0043] In this way, in conjunction with the operation of storing the seat cushion 2 in the floor F (the operation of the seat body diving down), the storage part 4 can be pulled to the rear side of the seat cushion 2. Therefore, even when the seat cushion 2 is stored in the floor F, the storage part 4 can be pulled to a position where it does not get in the way. Note that even when the seat cushion 2 is in the normal position without diving down, the storage part 4 is configured to be pullable to the rear side of the seat cushion 2 by the rotating member 5.

[0044] On the lower surface of the seat cushion 2, a recess 2b for storing the storage part 4 and a depression 2c for storing the fixing part 6 are formed. The recess 2b is provided on the rear side in the front-rear direction of the seat cushion 2 and is formed to be recessed upward from the lower surface of the seat cushion 2. The depression 2c is provided on the front side in the front-rear direction of the seat cushion 2 and is formed to be recessed upward from the lower surface of the seat cushion 2.

[0045] As shown in FIG. 4, when the storage part 4 is stored in the recess 2b when in the storage position, the lower surface of the seat cushion 2 can be placed (stored) in contact with the floor F. In this way, when the seat body is in the folded state, since the storage part 4 fits inside the recess 2b, the seat body can be folded small.

[0046] <Rotating member> As shown in FIGS. 2 and 3, the pivoting member 5 is a link member that connects the seat cushion 2 and the storage portion 4 and moves the storage portion 4 relative to the seat cushion 2. The pivoting member 5 includes a first link 20 pivotally attached to the first arm portion 10, a second link 21 attached to the storage portion 4, a connecting link 22 that connects the first link 20 and the second link 21 and is pivotally attached to the first link 20 and the second link 21, and a moving portion 23 attached to the connecting link 22 that moves the connecting link 22 rearward relative to the seat cushion 2. The moving portion 23 has a curved connecting link 24 that connects the cushion frame 2a and the connecting link 22 and is pivotally attached to the cushion frame 2a and the connecting link 22.

[0047] The pivoting member 5 is composed of a plurality of links, and each link is pivotally connected to each other. More specifically, as shown in FIGS. 2 and 3, the pivoting member 5 includes a first pivot shaft 5a that pivotally connects the front end of the first link 20 to the first arm portion 10, a second pivot shaft 5b that pivotally connects the rear end of the first link 20 and the upper end of the connecting link 22 to each other, a third pivot shaft 5c that pivotally connects the lower end of the connecting link 22 and the rear end of the second link 21 to each other, a fourth pivot shaft 5d that pivotally connects the front end of the second link 21 to the storage portion 4, a fifth pivot shaft 5e that pivotally connects the upper end of the connecting link 24 to the second arm portion 12, and a sixth pivot shaft 5f that pivotally connects the lower end of the connecting link 24 and the central portion of the connecting link 22 to each other. Note that a biasing mechanism (such as a torsion spring) that assists the operation of switching the storage portion 4 from the normal position to the storage position may be provided on each pivot shaft of the pivoting member 5.

[0048] As shown in FIG. 3, the first link 20 is an elongated link that extends linearly in the front-rear direction. The front end of the first link 20 is pivotally attached to the central portion of the first arm portion 10 attached to the seat cushion 2. Therefore, as shown in FIG. 4, the first link 20 moves forward in a state substantially parallel to the floor F in conjunction with the forward pivoting of the first arm portion 10.

[0049] As shown in FIG. 3, the connection link 22 is a long link that extends linearly in the vertical direction. The upper end of the connection link 22 is rotatably attached to the rear end of the first link 20. Therefore, as shown in FIG. 4, the connection link 22 rotates about the sixth rotation axis 5f in conjunction with the forward movement of the first link 20.

[0050] As shown in FIG. 3, the second link 21 is a long link that extends linearly in the front-rear direction. The rear end of the second link 21 is rotatably attached to the lower end of the connection link 22. Therefore, as shown in FIG. 4, the second link 21 moves rearward in conjunction with the forward rotation of the connection link 22 about the sixth rotation axis 5f and the rearward movement of the rear end of the connection link 22.

[0051] As shown in FIG. 3, the moving part 23 is attached to the connection link 22 and moves the connection link 22 rearward with respect to the seat cushion 2. As shown in FIG. 4, as the moving part 23 moves the connection link 22 rearward, the second link 21 moves rearward with respect to the seat cushion 2, so that the storage part 4 moves rearward from the normal position toward the storage position.

[0052] As shown in FIG. 3, the connecting link 24 is a link having a banana shape that curves convexly forward. Since the connecting link 24 has a curved shape, the lower end of the connection link 22 moves smoothly rearward in conjunction with the switching operation of the switching member 3.

[0053] In addition, in the present embodiment, as shown in FIGS. 3 and 4, by providing the moving part 23, the moving part 23 is configured to pull the storage part 4 rearward in response to the switching operation of the switching member 3. However, the present invention is not limited to this, and the vehicle seat S may be configured without the moving part 23. Further, the switching member 3 and the rotating member 5 may be configured not to be interlocked. For example, when the moving part 23 is not provided, the occupant may push the storage part 4 backward by hand to move the storage part 4 from the normal position to the storage position. At this time, the storage part 4 and the rotating member 5 may be stored inside the concave part 2b of the seat cushion 2, or may be stored below the lower surface of the seat cushion 2.

[0054] <Fixed part> As shown in FIG. 3, the fixing part 6 is an arm member that is long in the vertical direction and fixes the storage part 4 in the normal position. The fixing part 6 is rotatably provided at the lower end of the front part of the seat cushion 2. In other words, the fixing part 6 rotates in the front-rear direction around the support shaft 6a with respect to the seat cushion 2. A locking part 6b (for example, a member such as a latch, a J-hook, or a hook-and-loop fastener) is provided at the lower end of the fixing part 6. The locking part 6b locks to a locked part formed on the upper surface of the storage main body part 4a of the storage part 4.

[0055] The support shaft 6a is configured to be able to hold the orientation of the storage part 4 (the arm angle of the fixing part 6 in a side view of the seat) at a predetermined position when the storage part 4 is in the normal position. The angle holding method may be a known locking mechanism that locks at a predetermined position and unlocks with a button, or a mechanism that holds at a predetermined angle with frictional force, etc. Therefore, as shown in FIG. 3, when the storage part 4 is in the normal position, it is locked to the fixing part 6 by the support shaft 6a so that the orientation of the opening 4a1 can be adjusted.

[0056] When in the normal position shown in FIG. 3, the storage part 4 is locked to the locking part 6b of the fixing part 6 and fixed below the front part of the seat cushion 2. When in the storage position shown in FIG. 4, the storage part 4 is stored below the rear part of the seat cushion 2 in a state where the locking with the locking part 6b of the fixing part 6 is released. At this time, the fixing part 6 is stored in the recess 2c formed on the lower surface of the seat cushion 2. When the seat body dives down and abuts against the floor F, since the fixing part 6 is stored in the recess 2c, the seat body fits well without the fixing part 6 getting in the way.

[0057] Thus, since the storage portion 4 is fixed by the fixing portion 6, the storage portion 4 can be held at a suitable position in the normal position. Further, since the angle of the storage portion 4 (the direction of the opening portion 4a1) can be adjusted, it becomes easier to take out the articles stored in the storage portion 4. Specifically, when pulling out the cover 4b from the storage portion 4 and attaching it to the back surface of the seat back 1 (when covering the seat back 1 and the seat cushion 2 with the cover 4b), by setting the angle of the storage portion 4 upward, the cover 4b can be smoothly pulled out upward. Also, when pulling out the cover 4b from the storage portion 4 and attaching it to the interior parts arranged in the front (when covering the floor F in front of the vehicle seat S), by setting the angle of the storage portion 4 downward, the cover 4b can be smoothly pulled out downward.

[0058] Next, with reference to FIGS. 3 and 4, the movement of the seat body by the switching member 3 and the movement of the storage portion 4 by the rotating member 5 will be described. The storage portion 4 moves from the normal position to the storage position in response to the operation of switching the seat body from the use state to the folded state.

[0059] More specifically, first, the occupant removes the locking portion 6b of the fixing portion 6 from the storage main body portion 4a. Then, when the occupant tilts the seat back 1 forward, the second arm portion 12 moves forward, and the first arm portion 10 rotates forward about the first axis 3a. In conjunction with the rotation of the first arm portion 10, the first link 20 moves forward. At this time, the upper end of the connecting link 24 moves forward in conjunction with the forward movement of the second arm portion 12.

[0060] When the first link 20 moves forward, the central portion of the connection link 22 is pushed up by the lower end (the sixth rotation axis 5f) of the connecting link 24, so the rear end (the third rotation axis 5c) of the connection link 22 moves backward. By the rear end of the connection link 22 moving backward, the second link 21 moves backward, and the storage portion 4 moves backward with respect to the seat cushion 2. When the lower surface of the seat cushion 2 abuts against the floor F, the storage portion 4 is stored in the concave portion 2b of the seat cushion 2. Further, the fixing portion 6 rotates about the support shaft 6a and is stored in the recess 2c of the seat cushion 2.

[0061] In this way, in conjunction with the operation in which the switching member 3 switches the seat back 1 and the seat cushion 2 from the use state to the folded state, the moving portion 23 moves the connection link 22 backward with respect to the seat cushion 2. Then, the storage portion 4 moves from the normal position to the storage position as the rotating member 5 rotates with respect to the seat cushion 2. When returning the storage portion 4 from the storage position to the normal position, the movement is opposite to the above-described movement.

[0062] With the above configuration, the rotating member 5 pulls the storage portion 4 backward, and the storage portion 4 moves below the seat cushion 2. Since the storage portion 4 is pulled backward from the front end portion of the seat cushion 2, the space below the seat cushion 2 can be effectively utilized. Specifically, other articles can be stored below the front end portion of the seat cushion 2. Further, since the storage portion 4 is not disposed below the front end portion of the seat cushion 2, the seat body can be dive-down.

[0063] In particular, since the rotating member 5 is composed of a plurality of links, the storage portion 4 can be pulled below the seat cushion 2 with a simple configuration. Further, since the connection link 22 is moved backward by the moving portion 23, the storage portion 4 can be pulled below the seat cushion 2 with a simple configuration. Also, the separation distance between the seat cushion 2 and the storage portion 4 in the vertical direction can be narrowed by a plurality of links. Therefore, the space below the seat cushion 2 can be utilized more effectively.

[0064] In addition, the storage portion 4 can be pulled rearward in conjunction with the operation of storing the seat back 1 and the seat cushion 2 in the floor F. Therefore, even when the seat cushion 2 is stored in the floor F, the storage portion 4 can be easily pulled into a position where it does not interfere. At this time, since the storage portion 4 is pulled inside the recess 2b formed on the lower surface of the seat cushion 2, the seat cushion 2 can be stored more compactly. Note that the storage portion 4 moves simultaneously with the seat body by a link mechanism so as to be interlocked with the switching operation of the seat body, but it is not necessarily required to move simultaneously. For example, after the seat body is in the folded state, the storage portion 4 may move to the storage position.

[0065] <Modification Example 1> FIGS. 5 and 6 are side views of the vehicle seat S according to Modification Example 1 of the first embodiment. In the vehicle seat S according to Modification Example 1, the configuration of the moving portion 33 is different from that of the moving portion 23. The moving portion 33 has a telescopic member 34 that connects the cushion frame 2a and the connection link 22 and is telescopic between the cushion frame 2a and the connection link 22.

[0066] The telescopic member 34 is, for example, a coil spring and biases the connection link 22 in a direction to push it rearward. The telescopic member 34 smoothly moves the lower end of the connection link 22 rearward in conjunction with the switching operation of the switching member 3. Note that the telescopic member 34 may be a member that expands and contracts in a direction to move the connection link 22 rearward, and may be an elastic member such as a rubber string, for example.

[0067] The storage portion 4 moves from the normal position shown in FIG. 5 to the storage position shown in FIG. 6 in conjunction with the operation of switching the seat body from the use state to the folded state by the telescopic member 34. Specifically, when the first link 20 moves forward in conjunction with the rotation of the first arm portion 10, the telescopic member 34 extends so as to push up the central portion (the sixth rotation axis 5f) of the connection link 22, so that the rear end (the third rotation axis 5c) of the connection link 22 moves rearward.

[0068] In this way, since the connection link 22 is moved rearward by the telescopic member 34 of the moving part 33, the storage part 4 can be retracted below the seat cushion 2 with a simple configuration.

[0069] <Manufacturing method> A manufacturing method of the vehicle seat S will be described. In the manufacturing method of the vehicle seat S, a seat body having a seat back 1 that supports the back of an occupant and a seat cushion 2 that supports the buttocks of the occupant is prepared. Then, a switching member 3 is attached so as to connect the seat back 1 and the seat cushion 2. At this time, the seat body may be configured to be switchable between a use state and a folded state by the switching member 3. Then, a rotating member 5 is attached to the seat cushion 2 so as to be rotatable, and a storage part 4 capable of storing an article is connected to the seat cushion 2 via the rotating member 5.

[0070] When connecting the storage part 4 to the seat cushion 2, the storage part 4 is disposed below the seat cushion 2. At this time, the storage part 4 is attached to the rotating member 5 attached to the seat cushion 2 so as to move between a normal position where the storage part 4 is disposed below the front part of the seat cushion 2 and a storage position where the storage part 4 is stored below the seat cushion 2 at a position rearward of the normal position. By the above manufacturing method, a vehicle seat S that can effectively utilize the space below the seat cushion 2 can be manufactured.

[0071] <Second Embodiment> Next, the vehicle seat S2 of the second embodiment will be described with reference to FIGS. 7 and 8. Note that descriptions of configurations overlapping with those of the above-described vehicle seat S will be omitted. In the vehicle seat S2, mainly the configuration of the switching member 103 is different.

[0072] As shown in FIG. 7, the vehicle seat S2 is mainly composed of a seat back 101 and a seat cushion 102. The seat back 101 is provided with a back frame 101a serving as a skeleton inside thereof. The seat cushion 102 is provided with a cushion frame 102a serving as a skeleton inside thereof. The cushion frame 102a is rotatably attached to the back frame 101a.

[0073] As shown in FIGS. 7 and 8, the vehicle seat S2 includes a switching member 103 for switching the seat back 101 and the seat cushion 102 between a use state and a folded state, a storage portion 104 disposed below the seat cushion 102, a rotating member 105 rotatably attached to the seat cushion 102, and a fixing portion 106 for fixing the storage portion 104 at a normal position. The rotating member 105 connects the seat cushion 102 and the storage portion 104 via the switching member 103, and moves the storage portion 104 with respect to the seat cushion 102.

[0074] As shown in FIGS. 7 and 8, the switching member 103 has a first arm portion 110 rotatably attached to a front portion of the cushion frame 102a, a first support portion 111 rotatably supporting the first arm portion 110 with respect to the floor F, and a frame support portion 113 rotatably attached to a lower end portion of the back frame 101a.

[0075] The switching member 103 has a first shaft 103a rotatably connecting a lower end of the first arm portion 110 to the first support portion 111, a second shaft 103b rotatably connecting an upper end of the first arm portion 110 to a front end of the cushion frame 102a, a third shaft 103c rotatably connecting the cushion frame 102a to the back frame 101a, and a fourth shaft 103d rotatably connecting a lower end of the back frame 101a to the frame support portion 113.

[0076] The first arm portion 110 is an elongated member extending toward the floor F and is rotatably attached to a front portion of the cushion frame 102a. The first support portion 111 is a rail device bracket disposed on the floor F, and rotatably supports the first arm portion 110 with respect to the floor F. The frame support portion 113 is attached to the first support portion 111, and rotatably supports the back frame 101a with respect to the floor F.

[0077] Next, with reference to FIGS. 7 and 8, the movement of the seat body by the switching member 103 and the movement of the storage portion 104 by the rotating member 105 will be described. First, the occupant releases the locked state between the fixing portion 106 and the storage portion 4. When the occupant tilts the seat back 101 forward, the cushion frame 102a moves forward, and the first arm portion 110 rotates forward about the first shaft 103a. In conjunction with the rotation of the first arm portion 110, the first link 120 moves forward. At this time, the upper end of the connecting link 124 moves forward in conjunction with the forward movement of the cushion frame 102a.

[0078] When the first link 120 moves forward, the central portion of the connection link 122 is pushed up by the lower end of the connecting link 124, and the rear end of the connection link 122 moves rearward. By the rearward movement of the rear end of the connection link 122, the second link 121 moves rearward, and the storage portion 104 moves rearward with respect to the seat cushion 102. Also, the fixing portion 106 rotates about the support shaft 106a and is disposed rearward of the front end of the seat cushion 2.

[0079] In this way, in conjunction with the operation of the switching member 103 for switching the seat back 101 and the seat cushion 102 from the use state to the folded state, the moving portion 123 (connecting link 124) moves the connection link 122 rearward with respect to the seat cushion 102. Then, the storage portion 104 moves from the normal position to the storage position as the rotating member 105 rotates with respect to the seat cushion 102.

[0080] <Modification 2> FIG. 9 is a side view of the vehicle seat S according to Modification 2 of the second embodiment. In the vehicle seat S2 of Modification 2, the configuration of the moving part 133 is different. Specifically, as the moving part 133, a biasing member 134 is provided instead of the connecting link 124.

[0081] The moving part 133 is attached to the rotation axis of the first link 120, the connection link 122, or the second link 121, and has a biasing member 134 that biases the connection link 122 rearward. The biasing member 134 is, for example, a torsion spring, and assists the operation of switching the storage part 104 between the normal position and the storage position. The biasing member 134 is provided on each rotation axis of the rotating member 105. Specifically, the biasing member 134 includes a first biasing member 134a attached to the first rotation axis 105a, a second biasing member 134b attached to the second rotation axis 105b, and a third biasing member 134c attached to the third rotation axis 105c.

[0082] As the first support part 111 rotates the first arm part 110 to switch the seat back 101 and the seat cushion 102 from the use state to the folded state, the biasing member 134 moves the connection link 122 rearward with respect to the seat cushion 102. In this way, since the connection link 122 is moved rearward by the biasing force of the biasing member 134 of the moving part 133, the storage part 104 can be pulled under the seat cushion 102 with a simple configuration.

[0083] <Third Embodiment> Next, the vehicle seat S3 of the third embodiment will be described with reference to FIGS. 10 to 12. Note that the description of the configurations overlapping with the above-described vehicle seats S and S2 will be omitted. As shown in FIG. 10, the vehicle seat S3 is mainly composed of a seat back 201 and a seat cushion 202.

[0084] As shown in FIGS. 10 to 12, the vehicle seat S3 includes a switching member 203 that switches the seat back 201 and the seat cushion 202 between a use state, a folded state, and a tip-up state, a storage portion 204 disposed below the seat cushion 202 and capable of storing articles, a rotating member 205 rotatably attached to the seat cushion 202, and a fixing portion 206 that fixes the storage portion 204 to a normal position. The rotating member 205 has a moving portion 223 that moves the connection link 222 rearward with respect to the seat cushion 202. The rotating member 205 directly connects the seat cushion 202 and the storage portion 204 and moves the storage portion 204 with respect to the seat cushion 202.

[0085] As shown in FIG. 10, the use state is a state in which a passenger can be seated and the seat back 201 is in an upright position. As shown in FIG. 11, the folded state is a so-called dive-down state in which the seat back 201 is folded from the use state so as to overlap the seat cushion 202, and the seat back 201 is stored on the vehicle floor F. The vehicle seat S3 is provided on the upper stage of the floor F and stored on the lower stage of the floor F. As shown in FIG. 12, the tip-up state is a state in which the front end portion of the seat cushion 202 is flipped upward and folded so as to overlap the seat back 201 in the front-rear direction.

[0086] As shown in FIG. 10, the moving portion 223 is attached to the central portion of the connection link 222 and has a pulling member 224 that pulls the connection link 222 rearward. The tension member 224 is, for example, a wire member that connects the connection link 22 and the seat back 201. The front end portion of the tension member 224 is attached to the central portion of the connection link 22, and the rear end portion is attached to the back surface of the seat back 201. Specifically, the tension member 224 extends rearward from the connection link 22, passes under the seat cushion 2, and is fixed to the attachment portion 224a near the pivot connection portion of the seat back 201 and the seat cushion 202. Note that the extending direction of the tension member 224 is switched via the reel member 224b.

[0087] As shown in FIGS. 10 and 11, in conjunction with the operation of folding the seat back 101, the tension member 224 pulls the connection link 222, and the connection link 222 is moved rearward with respect to the seat cushion 202. In this way, since the connection link 122 is moved rearward by the tension of the tension member 224 of the moving portion 223, the storage portion 204 can be pulled under the seat cushion 102 with a simple configuration.

[0088] In this embodiment, since the fixing portion 206 is fixed to the storage portion 204, when the storage portion 204 is pulled rearward, the storage portion 204 is held in the storage position by the fixing portion 206. Therefore, as shown in FIG. 11, when the seat body is in the folded state, the storage portion 204 can be stored at a position close to the seat cushion 202 in the vertical direction (a position where the storage portion 204 and the floor F are separated in the vertical direction). Further, as shown in FIG. 12, when the seat body is in the tip-up state, the storage portion 204 can be stored at a position close to the back surface (front surface) of the seat cushion 202.

[0089] <Fourth Embodiment> Next, the vehicle seat S4 of the fourth embodiment will be described with reference to FIG. 13. Note that the description of the configurations overlapping with the above-described vehicle seats S, S2, and S3 will be omitted. As shown in FIG. 13, the vehicle seat S4 is a rear seat in a vehicle V having two rows of seats in the front-rear direction. In front of the vehicle seat S4, a front seat FS is arranged. The front seat FS corresponds to an interior component arranged in front of the vehicle seat S4.

[0090] As shown in FIG. 13, the vehicle seat S4 is mainly composed of a seat back 301 and a seat cushion 302. The vehicle seat S4 is provided with a storage portion 304 that is arranged below the seat cushion 302 and can store articles. Although not shown in FIG. 13, the vehicle seat S4 is provided with a rotating member, a switching member, and a fixing portion.

[0091] A cover 304b that covers the floor F of the vehicle V is stored in the storage portion 304. The cover 304b is fixed at a position covering the floor F by a cover fixing portion C provided on the front seat FS or a cover fixing portion C provided on the floor F. In addition, guide members 304e are provided at both ends in the seat width direction of the storage portion 304. The guide member 304e is a member having a concave shape and holds the cover 304b from the side. When the cover 304b is used, the cover 304b pulled downward is guided by the guide member 304e.

[0092] When the storage portion 304 is in the normal position, the occupant can pull out the cover 304b from the storage portion 304 and attach it to the front seat FS, which is a front vehicle seat arranged in the front. More specifically, the front end portion of the cover 304b is attached to a base portion 511a that spans the left and right rail devices 511 of the front seat FS. The base portion 511a is a member that extends longitudinally in the seat width direction. A plurality of cover fixing portions C are provided on the upper surface of the base portion 511a. The cover fixing portion C of the front seat FS includes attachment members such as hook-and-loop fasteners, buttons, and magnets. In this way, the cover 304b is fixed to the base portion 511a of the front seat FS by the cover fixing portion C.

[0093] Further, the floor F has a plurality of cover fixing portions C at positions corresponding to both ends in the sheet width direction of the cover 304b. Both ends of the cover 304b are attached to the cover fixing portions C provided on the floor F. The cover fixing portions C of the floor F include, for example, clips. The cover 304b is guided forward by the cover fixing portions C such as clips. Thus, the cover 304b is fixed to the floor F by the cover fixing portions C. Note that the cover fixing portions C of the floor F may be attachment members such as hook-and-loop fasteners, buttons, magnets, etc.

[0094] Thus, the cover fixing portions C can fix the cover 304b at a suitable position even when the floor F is covered with the cover 304b. Further, the guide member 304e can guide the cover 304b to a suitable position. Note that, although the front seat FS has been described as an example of the interior part to which the cover 304b is attached, the present invention is not limited thereto. For example, the cover 304b may be attached to interior parts such as door pillars and instrument panels.

[0095] In the above embodiment, the vehicle seat used in an automobile has been described as a specific example. However, the present invention is not particularly limited, and in addition to two-wheeled seats for motorcycles, vehicle seats for trains, buses, etc., vehicle seats for airplanes, ships, etc., various seats such as office chairs for work, car seats, and children's seats for shopping carts can be used.

[0096] In the present embodiment, the vehicle seat according to the present invention has been mainly described. However, the above embodiment is merely an example for facilitating the understanding of the present invention, and does not limit the present invention. The present invention can be changed and improved without departing from its gist, and it goes without saying that equivalents of the present invention are included therein.
