Here, the bottom plate 11 is formed in a shape in which a front region thereof is wide and wide in the width direction as an escape hole 11A. And in the location near each edge part of the width direction of the baseplate 11, the escape holes 11B and 11B extended further to the back side from the escape hole 11A are formed. The escape holes 11A and the escape holes 11B and 11B are formed to avoid interference with the constituent members of the second sheet 20 when the second sheet 20 (see FIG. 1) is accommodated inside the container 10. ing.

  Specifically, the escape hole 11A is formed so as to avoid interference with the bottom surface portion of the seat cushion 22 in a posture of being dropped onto the floor F. The escape holes 11B and 11B are formed so as to avoid interference with link arms 24A and 24B and an upper rail 25A connected to a second seat 20 described later in FIG. Returning to FIG. 2, the side plates 12, 12 are erected along both side edges of the above-described bottom plate 11.

  These side plates 12 and 12 are formed with penetrating handles 12A and 12A serving as grips when the storage box 10 is pulled out to the front side at a position near the front end. And the long holes 12H and 12H extended in the front-back direction along this upper edge are penetrated and formed in the upper edge location near the front end of each side plate 12 and 12. As shown in FIG. The rear plate 13 is erected along the rear edge of the bottom plate 11 described above. The rear plate 13 is formed integrally with the bottom plate 11 and the side plates 12 and 12.

  Next, the top plate 14 is arranged in a fashion that connects the upper edges of the side plates 12, 12. The top plate 14 is disposed and formed so as to cover the formation region of the long holes 12H and 12H formed in the side plates 12 and 12 described above from above. Accordingly, the storage box 10 has a shape in which a part of the front region of the upper surface portion is covered with the top plate 14 and the remaining rear region is opened. The arrangement of the top plate 14 reinforces the front structure of the storage box 10 that has been lowered by the arrangement of the escape holes 11 </ b> A, the long holes 12 </ b> H and 12 </ b> H, and the opening / closing lid 15.

  Next, the open / close lid 15 is fitted with the pins 15P and 15P provided on both side portions on the upper end side thereof in the long holes 12H and 12H formed through the side plates 12 and 12, respectively. , 12 is pivotally connected to be rotatable. Here, the pins 15P and 15P correspond to the coupler of the present invention. As a result, the opening / closing lid 15 can perform an opening / closing operation for opening and closing the internal space of the storage box 10 in accordance with the rotational movement around the connection point of the pins 15P and 15P. Yes. Here, a handle 15 </ b> A serving as a handle when the opening / closing lid 15 is opened / closed is formed in a concave shape at the center lower end portion of the opening / closing lid 15.

  And the metal plate 15B ... is integrally stuck by the lower end part of the right-and-left both ends side of the opening-and-closing lid | cover 15 on the front and back both surfaces. These metal plates 15B are attached to magnets 16A and 16A installed at the corners of the side plates 12 and 12 and the bottom plate 11 when the open / close lid 15 is closed. Thus, the opening / closing lid 15 is held in a closed state by the force with which the metal plates 15B and the magnets 16A and 16A stick together. As shown in FIG. 3, the opening / closing lid 15 is opened and raised against the force with which the metal plate 15 </ b> B and the magnets 16 </ b> A and 16 </ b> A stick to each other, thereby opening the inner space of the storage box 10. It becomes a state.

  Here, each of the long holes 12H and 12H is formed in a shape in which the front and rear end portions are slightly hung downward. Thereby, the opening / closing operation | movement of the opening-and-closing lid | cover 15 can be performed now without sliding the pins 15P and 15P to the back side in the front-end part position of the long holes 12H and 12H. Then, as shown in FIG. 4, the open / close lid 15 is guided to the shape of the long holes 12H and 12H by pushing the pins 15P and 15P slightly upward from the above-mentioned opened and raised positions. However, it is transferred to the rear side.

  Then, in this state, the metal plate 15B attached to the surface of the opening / closing lid 15 is attached to the magnets 16B, 16B installed on the back surface of the top plate 14 of the storage box 10, whereby the opening / closing lid 15 is The posture is superposed on the back surface of the plate 14. Thereby, the storage box 10 is held in a state in which the opening / closing lid 15 is opened and the internal space is opened. Therefore, from this state, the second sheet 20 (see FIG. 1) or an object can be accommodated or taken out from the container 10 in a state in which the hand is released from the opening / closing lid 15.

  Then, as shown in FIG. 5, the opening / closing lid 15 is further slid rearward from the position held on the back surface side of the top plate 14 to cause the pins 15P and 15P to be rear ends of the long holes 12H and 12H. And by closing the pins 15P and 15P downward, the metal plate 15B attached to the back surface of the magnet 16C is set at a position retracted from the magnets 16A and 16A. , 16C is attached. As a result, the opening / closing lid 15 is similarly held at a position retracted from the closed position when it is attached to the magnets 16A and 16A described above with reference to FIG.

  Specifically, the opening / closing lid 15 is held by being attached to the magnets 16C and 16C at a position on the bottom plate 11 on the rear side that is removed from the escape hole 11A. Thereby, the storage box 10 is in a state in which the storage object can be enclosed in the region having the seating surface formed by the bottom plate 11. And as FIG. 8 shows, even if the seating person of the 3rd seat 30 pulls a leg part back, the leg part becomes difficult to hit the opening / closing lid 15 by the arrangement | positioning position of the opening / closing lid 15 moving backward.

  Here, referring back to FIG. 2, eight rollers R... Are provided at the left and right sides of the bottom of the storage box 10. Thereby, as shown in FIG. 6, the storage box 10 is pulled by the operator by pulling the handles 12 </ b> A and 12 </ b> A of the side plates 12 and 12 with their hands, thereby rolling the rollers R. It is pulled out smoothly to the front side. At this time, as shown in the figure, it is preferable that the second seat 20 is folded up and moved forward so that the storage box 10 can be pulled out further forward.

  And by pulling out the storage box 10 in this way, the storage box 10 comes out of the storage space 34, and the opening of the upper surface is exposed to the outside. Thereby, it becomes possible to accommodate and take out an object from the opening of the upper surface portion of the housing box 10. Further, as described above with reference to FIG. 7, the upper opening of the storage box 10 can be exposed to the outside by raising the seat cushion 32 of the third seat 30. At this time, the upper opening of the storage box 10 can be more widely exposed to the outside by pulling out the storage box 10 slightly forward.

  Next, the configuration of the second sheet 20 will be described in detail. As shown in FIG. 1, the second seat 20 includes a seat back 21 that serves as a backrest and a seat cushion 22 that serves as a seating portion. Here, the seat back 21 is connected to the rear end of the seat cushion 22 via the reclining device 23 at the lower ends of both sides thereof. As a result, the seat back 21 is fixed to a posture position standing up with respect to the seat cushion 22 by switching the operating state of the reclining device 23, or the fixed state is released and the seat back 21 is moved forward to the upper surface of the seat cushion 22. It has come to be.

  Note that the basic configuration of the reclining device 23 is a known configuration disclosed in a document such as Japanese Patent Application Laid-Open No. 2002-360368, and a detailed description thereof will be omitted. The reclining device 23 is always held in a locked state in which the backrest angle of the seat back 21 is fixed. The locked state of the reclining device 23 is released by an operation of pulling down the operation lever 21A provided at the left shoulder opening of the seat back 21 toward the front side in the figure.

  Here, although not shown in the figure, a spring member that urges the seat back 21 in the forward-tilting direction at all times is hooked between the seat back 21 and the seat cushion 22. Thus, the seat back 21 is tilted forward to the upper surface portion of the seat cushion 22 by urging by releasing the locked state of the reclining device 23 by releasing the operation lever 21A.

  By the way, the seat cushion 22 is linked to a pair of left and right slider devices 25 arranged on the floor F by two link arms 24A and 24B having a pair of left and right structures. . Here, the slider device 25 has a rail-shaped lower rail 25B fixedly installed in the floor F, and a rail-shaped upper rail 25A fitted into the lower rail 25B so as to be slidable in the direction in which the rail extends.

  Each of the lower rail 25B and the upper rail 25A is arranged and formed so that the rail shape extends straight in the longitudinal direction of the vehicle. Specifically, as shown in FIG. 2, the lower rail 25 </ b> B extends and is formed to an internal position of the accommodation space 34 formed in the lower part of the third seat 30. Although not shown, the slider device 25 regulates the sliding of the upper rail 25A relative to the lower rail 25B when a lock claw installed on the upper rail 25A enters over the through holes formed in both rails. It has a configuration.

  The lock claw is normally urged in the operating direction to enter the through hole by an urging force of a spring member (not shown). As shown in FIG. 1, the lock claw works against the above-mentioned bias in conjunction with the movement of the second seat 20 being dropped onto the floor F along with the link movement of the link arms 24A and 24B. It is designed to be removed from the through hole.

  Accordingly, when the second seat 20 is dropped onto the floor F, the upper rail 25A is switched to a slidable state. Therefore, by sliding the second seat 20 in the posture dropped onto the floor F to the vehicle rear side as it is, the second seat 20 can be accommodated in the accommodating space 34 under the third seat 30.

  By the way, the pair of left and right link arms 24A and 24B described above are pivotally connected at their lower ends to the side plates of the L-shaped bracket L fixedly installed on the upper surface of each upper rail 25A. Yes. And the upper end part of each link arm 24A, 24B is pivotally connected by the side part of the frame of the seat cushion 22 so that rotation is possible. The link arms 24A and 24B move the seat cushion 22 up and down between a normal seating use position and a lying position where the seat cushion 22 is dropped on the floor F by the up-and-down rotation accompanying the link movement.

  The up-and-down rotation of the link arms 24A, 24B is locked by a rotation stopper device (not shown) provided at the upper end connecting portion of the front link arm 24A. Here, the basic configuration of the rotation-retaining device is substantially the same as that of the reclining device 23 described above, and the rotation-retaining device is always held in a locked state where the rotation-retaining device is rotationally retained. This locked state is released by a pulling down operation of the operation lever 21A provided at the left shoulder of the seat back 21 described above.

  Therefore, by performing the release operation of the operation lever 21A, the seat back 21 is brought down on the upper surface portion of the seat cushion 22, and the entire second seat 20 is dropped onto the floor F. Then, since the slide lock state of the slider device 25 is released, the second seat 20 in the folded posture can be slid rearward as it is and accommodated in the accommodating space 34 under the third seat 30. it can.

  Thus, according to the vehicle seat structure of the present embodiment, the storage box 10 that surrounds the storage space 34 is closed so that it cannot be seen from the outside by closing the open / close lid 15 when the second seat 20 is not stored. You will be able to store and remove things. As shown in FIG. 6, when the second sheet 20 is not accommodated, the accommodation box 10 is removed from the accommodation space 34 by the slide, so that the opening of the upper surface portion is exposed to the outside, and the object is removed from there. It can be stored and taken out.

  As shown in FIG. 8, the position of the opening / closing lid 15 can be retracted, so that the leg portion of the seated person of the third seat 30 does not easily hit the opening / closing lid 15. Therefore, the effective utilization of the accommodation space 34 can be improved without harming the seating feeling. Further, as shown in FIG. 4, the second seat 20 and other objects are accommodated in and removed from the accommodation space 34 by temporarily holding the opening / closing lid 15 in the opened position. Can be done easily.

  Further, as shown in FIG. 7, by raising the seat cushion 32 of the third seat 30, an object can be accommodated or taken out from the opening (accommodating space 34) of the accommodating box 10 exposed at the lower part thereof. . Thus, the accommodation space 34 formed in the lower part of the third sheet 30 can be effectively used as a space that functions as the accommodation box 10 when the second sheet 20 is not accommodated.

Although the embodiment of the present invention has been described with respect to one example, the present invention can be implemented in various forms in addition to the above-described example.
For example, the enclosure part (accommodation box) arrange | positioned in accommodation space may be integrally fixed to the support body and the 3rd sheet | seat. However, it should be noted that in this case, it is impossible to move the container box.
Moreover, the open / close lid may be configured to be laterally opened or downwardly opened. However, when opening downward, a separate device is required so that the opening / closing lid does not hinder the accommodation movement of the second sheet.

In addition, the second seat and the third seat may be separately formed in a size shape for seating each seated person. In this case, the size of the storage box (enclosure) is also formed according to the size of each storage space.
In addition, the slider device is shown as a mechanism for accommodating and moving the second seat into the third sheet accommodating space. However, the second seat may be accommodated and moved using the movement of another mechanism such as a link mechanism. good. Alternatively, the second seat may be removed from the floor and simply stored on the floor so as to be accommodated in the accommodation space.

Moreover, although the structure arrange | positioned in the lower space of the back seat of the sheet | seat arrange | positioned at the front side of a vehicle was shown, the arrangement | positioning relationship between sheets is not specifically limited. Therefore, for example, an accommodation space may be formed in the front sheet, and the rear sheet may be accommodated in the lower space of the front sheet. Moreover, you may make it accommodate the sheet | seat arrange | positioned in another position. In these cases, it is preferable to set the opening / closing lid toward the arrangement direction side of the sheet to be accommodated because it is easy to accommodate and take out.
Further, although the magnet is shown as a means for holding the opening / closing lid at each posture position where the opening / closing lid is opened / closed, other known attaching means may be used. Moreover, it may replace with a sticking structure and may employ | adopt a well-known hook structure and a fitting structure.
