The present invention relates to a novel rear seat structure in which an opening is formed in a seat back by moving a part forward and a long object can be placed through the opening.

As described above, various types of rear seat structures for vehicles that can use a part of the rear seat as a mounting portion for a long object have been proposed. As one of them, a part of the seat back of the rear seat is provided so as to be able to be moved forward, and a portion opened to the seat back is formed by the forward tilt, and a long object can be mounted through the opening. (For example, see Patent Document 1).
Japanese Utility Model Publication No. 61-113036

  However, in the case of the technique disclosed in Patent Document 1 described above, if the position in the width direction of the part where the seat back is moved forward is shifted to the left and right, it is difficult to put two people on the rear seat. On the other hand, if the part that forwards the seat back is provided in the center part of the rear seat, it is possible to hang on the rear seat comfortably, but the center part of the rear seat cushion is covered with the seat back part forward There is a drawback that it becomes difficult to use. For example, when a storage portion with a lid is provided at the center portion of the seat cushion, it is difficult to flip up the lid (also serving as the skin portion of the seat cushion).

  The present invention has been made to solve the above-described problems of the prior art, and can be used for a vehicle in which two persons can sit comfortably on the rear seat and the center portion of the rear seat cushion can be easily used. An object is to provide a rear seat structure.

  A vehicle rear seat structure according to claim 1 of the present invention includes a seat cushion center portion that is movable by dividing a width direction center portion of a seat cushion in a rear seat in the second and subsequent rows of the vehicle, and a seat back in the rear seat. A seat back center portion that is movable by dividing a width direction center portion, a shaft member that supports the seat back center portion so as to be swingable between a posture integrated with the seat back and a forward tilted posture, and the seat The cushion center part is provided with the link for moving over the position integrated with a seat cushion, and the movement position of the front side rather than the seat back center part of the said front-down position.

  A vehicle rear seat structure according to a second aspect of the present invention is the vehicle rear seat structure according to the first aspect, wherein the vehicle rear seat structure is swung to a rear end portion of the seat cushion center portion moved to the moving position and to the forwardly tilted posture. Further, the seat back center portion is configured to be connected to the upper end portion.

  A vehicle rear seat structure according to a third aspect of the present invention is the vehicle rear seat structure according to the first or second aspect, wherein the vehicle rear seat structure is swung between the surface of the seat cushion center portion moved to the moving position and the forward tilted posture. Further, the seat back center portion is configured to be substantially flush with the back surface.

  In the case of the vehicle rear seat structure according to the present invention, when the seat back center portion of the rear seats in the second and subsequent rows of the vehicle is swung from the posture integrated with the seat back via the shaft member to the forward tilted posture, An opening penetrating in the front-rear direction appears in the back center portion, and a long object can be mounted through the opening. In addition, the seat back center portion that has been tilted forward can be used as an armrest by adjusting the height of the back surface (becomes the upper surface in the forward tilted state). In addition, the seat cushion center part of the bag whose upper part is covered by the forward-backed seat back center part can be moved to the position of the front side of the forward-backed seat back center part by the link, and the center part of the rear seat cushion is moved forward. Since it is not covered with the seat back center portion, the center portion of the rear seat cushion can be easily used.

  In the case of the vehicle rear seat structure according to the second aspect, the rear end portion of the seat cushion center portion moved to the moving position is connected to the upper end portion of the seat back center portion in the forward tilted position. If there is no gap formed, the appearance can be improved.

  In the case of the vehicle rear seat structure according to claim 3, the surface of the seat cushion center portion moved to the moving position and the back surface of the seat back center portion swung forwardly are substantially flush with each other. Can also create a flat carrier.

  Hereinafter, the vehicle rear seat structure according to the present invention will be described in detail.

  FIG. 1 is a perspective view showing a rear seat to which the structure of the present invention is applied, and FIG. 2 is a schematic sectional view taken along line II-II in FIG. 3 is a perspective view showing a state in which the center portion of the rear seat is deformed, and FIG. 4 is a schematic cross-sectional view taken along line IV-IV in FIG.

  The rear seat 1 is a second seat disposed immediately behind the front seat, and includes a seat cushion 2 and a seat back 3. The seat back 3 is divided into two on the left and right sides in the width direction, and includes a left seat back 31 and a right seat back 32. The left seat back 31 is formed wider than the right seat back 32, and a seat back center portion 33 is provided on the right side of the left seat back 31.

  The left seat back 31 and the right seat back 32 are each configured to be able to recline independently. Further, the seat back center portion 33 is a shaft member that spans between the seat back center portion 33 and the left seat back 31. 34 is supported so as to be swingable. The shaft member 34 is disposed near the lower portion of the seat back center portion 33, and the seat back center portion 33 extends over a posture A in which the seat back center portion 33 is integrated with the seat back 3 and a forward tilted posture B in which the upper end portion 33 a falls to the front side. Swing. Note that, in the forward-facing posture B, the back surface 33 b of the seat back center portion 33 is set to be substantially horizontal, and an opening 35 penetrating in the front-rear direction appears at the position of the seat back center portion 33.

  The seat cushion 2 is divided into a left side seat cushion 21 on the left side in the width direction, a seat cushion center portion 22 at the center in the width direction, and a right side seat cushion 23 on the right side in the width direction. The left seat cushion 21 and the right seat cushion 23 are fixed to the vehicle body frame 5 in this embodiment. The seat cushion center portion 22 has a position C that is integrated with the seat cushion 2 by links 6a, 6b, 6c, and 6d provided at four locations on the front, rear, left, and right sides, and the seat back center portion 33 in the forward-downward posture B. It can move across the front movement position D. And in the movement position D, it sets so that the upper surface 22a of the seat cushion center part 22 may become substantially horizontal. The link 6a is the front left side, the link 6b is the front right side, the link 6c is the rear left side, and the link 6d is the rear right side.

  In addition, inside the seat cushion center portion 22, a storage portion 24 with a lid 25 is provided. In the illustrated example, the lid 25 includes a front rear opening lid 25a and a rear front opening lid 25b.

  In the structure of the rear seat 1 configured as described above, when a long object is mounted, the rear seat 1 is deformed as shown in FIG.

  First, the seat cushion center portion 22 is moved from a position C indicated by a two-dot chain line to a movement position D indicated by a solid line. Accordingly, the upper surface 22a of the seat cushion center portion 22 becomes substantially horizontal. Next, the seat back center portion 33 is swung from the posture A indicated by the two-dot chain line to the forward posture B indicated by the solid line, so that the back surface 33a of the seat back center portion 33 is made horizontal. As a result, the seat cushion center portion 22 is positioned in front of the seat back center portion 33 in the forward posture B.

  Therefore, in the case of the structure of the rear seat 1 of the present embodiment, if the seat back center portion 33 is swung forward from the posture A to the posture B via the shaft member 34, the seat back center portion 33 penetrates in the front-rear direction. The opening 35 appears, and a long object can be mounted through the opening 35. Further, the seat back center portion 33 that has been tilted forward can also be used as an armrest by adjusting the height of the rear surface 33a (which is the upper surface when tilted forward). Furthermore, the seat cushion center portion 22 that is covered with the seat back center portion 33 that has been tilted forward can be moved to the front moving position D with respect to the seat back center portion 33 that has been tilted forward by the links 6a to 6d. Since the cushion center portion 22 is not covered with the forward-backed seat back center portion 33, the seat cushion center portion 22 can be easily used. For example, when the seat cushion center portion 22 is provided with a storage portion 24 with a lid 25 as shown in FIGS. 2 and 4, the lid 25 can be easily opened and closed. In other words, since the seat cushion center portion 22 at the moving position D is positioned in front of the seat back center portion 33 in the forward tilted posture B, even if a long object is mounted through the opening 35, the long object is This is because it is difficult to cover the upper portion of the seat cushion center portion 22 at the movement position D. Further, even when a long object mounted through the opening 35 is in a state of covering the seat cushion center portion 22, the lid 25 can be opened and closed by slightly lifting the long object. On the other hand, when the seat cushion center portion 22 is covered with the forward-backed seat back center portion 33 as in the prior art, it is necessary to lift not only long objects but also the forward-backed seat back center portion 33, Furthermore, it is difficult for one person to open and close the lid 25, and the usability of the seat cushion center portion 22 is deteriorated.

  As shown in FIG. 2, the length L1 of the two front links 6a, 6b is set to be shorter than the length L2 of the two rear links 6c, 6d. Thus, even when the seat cushion center portion 22 is located at the position C and the front side is located above the rear side, the height position of the front side and the rear side is substantially the same when the movement position D is reached. Is possible. Further, by setting the length L1 and the length L2 to appropriate values, the rear end portion 22b of the seat cushion center portion 22 that has moved to the moving position D and the seat back center portion 33 that has become the forward-facing posture B are provided. Since the upper end portion 33a is connected, there is no gap formed when these are separated, and the appearance can be improved.

  Further, for example, by adjusting the heights of the links 6a, 6b, 6c, 6d and the height of the shaft member 34, the upper surface 22a of the seat cushion center portion 22 at the moving position D and the rear surface of the seat back center portion 33 in the forward posture B. Since 33b is substantially flush with the rear seat 1, a flat cargo bed can be created on the rear seat 1 as well. In this configuration, if the height of the cargo compartment immediately behind the rear seat 1 is made to coincide with the height of the flat cargo bed, it becomes possible to create a vast flat cargo bed extending from the top of the rear seat 1 to the cargo compartment. Long objects can be mounted very stably.

  In the above-described embodiment, the entire front and rear direction of the seat cushion center portion 22 is configured to move between the position C and the movement position D. However, the present invention is not limited to this, and the front and rear direction of the seat cushion center portion 22 is configured. Of course, it is also possible to adopt a configuration in which a part moves between the position C and the movement position D.

  Further, in the above-described embodiment, the portion from the upper end of the seat back center portion 33 to the shaft member 34 swings between the posture A and the forward tilted posture B. However, the present invention is not limited to this, and the seat back center is not limited thereto. A portion near the upper end portion 33a of the portion 33 may be left in the seat back, and a portion from the lower side to the shaft member 34 slightly below the upper end portion 33a may swing similarly.

  Further, in the above-described embodiment, in the configuration in which the seat cushion center portion 22 is moved by the link between the position C and the movement position D, means for forcibly holding the seat cushion center portion 22 at the position C and means for forcibly holding the movement at the movement position D In the present invention, as a means for forcibly holding the position C and a means for forcibly holding the movement position D, for example, a damper or a balance spring may be used in combination with the link. it can.

  Furthermore, in the above-described embodiment, the rear seat structure of the present invention is applied to the second seat disposed immediately behind the front seat, but the present invention is not limited to this. For example, the present invention can be similarly applied to the third and subsequent rear seats of a vehicle in which two or more rear seats are provided on the rear side of the front seat.
