The other end of the cargo box cable 76 is connected to the common cable 38 in the distributor 36 described above. Therefore, when the tip-up lever 40 is operated, the operating force is transmitted to the latch 72 via the common cable 38 and the cargo box cable 76, and the latch 72 is moved from the locked position indicated by the two-dot chain line in FIG. It is rotated to the unlock position indicated by the solid line in FIG. As a result, the restraint of the box body 46 by the latch 72 is released, and the box body 46 is moved to the use position by the biasing force of a spring (not shown).

  On the other hand, as shown in FIGS. 4 to 6, the tray 50 is formed in a shallow box shape with an open top, and includes a bottom wall portion 78, a front wall portion 80, a rear wall portion 82, and left and right sides. And a side wall 84. The tray 50 is formed, for example, in the size of about A4 size, and the length dimension along the sheet width direction is set to be equal to the length dimension along the sheet width direction of the box body 46. The tray 50 is set such that the length dimension along the front-rear direction of the sheet is shorter than the length dimension along the front-rear direction of the box body 46. The tray 50 is connected to the box body 46 via a link mechanism 48.

  The link mechanism 48 includes a pair of left and right four-joint links (parallel links) provided with a front link member 86 and a rear link member 88. The front link member 86 and the rear link member 88 are arranged side by side in the seat front-rear direction. Each of the front link member 86 and the rear link member 88 has an upper end portion (rear end portion) connected to a side wall portion 58 of the box body 46 via a connecting shaft 90, and a lower end portion (respective front end portion). ) Is connected to the side wall 58 of the tray 50 via a connecting shaft 92. The connecting shafts 90 and 92 are arranged such that the axial direction is along the sheet width direction, and the front link member 86 and the rear link member 88 are along the sheet width direction with respect to the box body 46 and the tray 50. It can rotate around the axis. As a result, the tray 50 can be moved up and down while maintaining a horizontal posture with respect to the box body 46, and the raised position (see FIG. 2) that contacts or approaches the lower end of the box body 46 and the box. It is movable between a lowering position (see FIG. 3) that is spaced downward with respect to the main body 46.

  In the state where the tray 50 is disposed at the raised position, the tray 50 overlaps the lower side of the box body 46, and the front link member 86 and the rear link member 88 are disposed along the sheet front-rear direction on the side of the tray 50. (See the two-dot chain line in FIG. 6). In this state, the tray 50 is arranged slightly above the bottom wall 54 of the frame 42, and the box body 46 and the tray 50 are slid (stored) with respect to the frame 42 to the storage position. It becomes possible. As shown in FIG. 5, in a state where the box body 46 and the tray 50 are located at the storage position (storage state), the tray 50 is accommodated between the box body 46 and the bottom wall 54 of the frame 42, and the cargo box 18. Is approximately equal to the volume of the frame 42.

  On the other hand, when the box body 46 is slid to the use position, the tray 50 is moved to the front side of the sheet from the front cover 24 of the base portion 16, and the movement (lowering) of the tray 50 to the lowered position is allowed. As a result, the tray 50 is lowered to the lowered position by its own weight, and the cargo box 18 is in the unfolded state (shown in FIGS. 3 and 4). In this unfolded state, the lower surface (bottom wall portion 78) of the tray 50 comes into contact with a floor mat (not shown) laid on the vehicle body floor portion, so that the tray 50 is supported on the vehicle body floor portion via the floor mat. Further, in this expanded state, the front link member 86 and the rear link member 88 are disposed so as to be inclined in a front-down state.

  A pair of left and right sliders 94 (guide members) are fixed to the bottom wall 54 of the frame 42 corresponding to the rear link member 88 described above. The left and right sliders 94 are formed in a long shape using a sheet metal material or the like, and are fixed to the upper surfaces of both ends of the bottom wall 54 in the sheet width direction along the front-rear direction of the sheet. The front end sides of the left and right sliders 94 protrude forward of the seat from the front end of the frame 42, and the front end portions of the left and right sliders 94 are formed with curved portions 94A that are curved downward. The left and right sliders 94 overlap the left and right rear link members 88 in the seat width direction, and come into sliding contact with the rear link members 88 when the box body 46 slides forward and backward with respect to the frame 42. Thus, the tray 50 moves up and down relative to the box body 46 in conjunction with the slide of the box body 46.

  Specifically, in a state where the box main body 46 is located at the use position, the curved portions 94A (front end portions) of the left and right sliders 94 face the upper end sides of the left and right rear link members 88 from the seat rear side. Be placed. When the box body 46 is slid to the retracted position by pushing the front wall portion 60 of the box body 46 to the seat rear side from this state, the rear link member 88 comes into sliding contact with the curved portion 94A of the slider 94, and the rear A reaction force to the front side of the seat and the upper side of the seat acts on the side link member 88. As a result, the rear link member 88 is rotated upward (clockwise in FIG. 6) around the connection shaft 90, and the front link member 86 that forms a parallel link with the rear link member 88 is rotated around the connection shaft 90. It is rotated upward. As a result, the tray 50 is moved to the raised position with respect to the box body 46 and is slid to the storage position together with the box body 46.

  On the other hand, when the box main body 46 is slid from the storage position to the use position, the rear link member 88 slides forward of the seat while sliding on the upper surface of the slider 94 and is also in sliding contact with the curved portion 94A. It is rotated downward around the connecting shaft 90 while being guided. As a result, the front link member 86 that forms a parallel link together with the rear link member 88 is rotated downward about the connecting shaft 90, and the tray 50 is lowered to the lowered position by its own weight. When the tray 50 is lowered to the lowered position (that is, the box body 46 is located at the use position), the tray 50 is located at the raised position (ie, the box body 46 is located at the retracted position). The height dimension (depth dimension) of the cargo box 18 increases, and the volume of the cargo box 18 increases (in this case, more than twice).

  Further, the cargo box 18 is provided with a pair of front and rear folding walls 98 and a pair of left and right nets 100 as luggage receiving members. The front and rear folding walls 98 include an upper plate 102 and a lower plate 104 that are formed into a long plate shape by a resin material or the like. The upper plate 102 and the lower plate 104 are arranged in a state where the longitudinal direction is along the sheet width direction, and one end portion in the width direction of the upper plate 102 and one end portion in the width direction of the lower plate 104 are in the sheet width direction. It is rotatably connected through a hinge portion 106 extending in the direction. Thereby, the front and rear folding walls 98 can be folded (deformable).

  The other end in the width direction of the upper plate 102 is connected to the front end of the left and right side wall portions 58 of the box body 46 via a connecting shaft 108, and the front side folding wall 98 is connected to the other side in the width direction of the lower plate 104. The end portion is connected to the front end portions of the left and right side wall portions 84 of the tray 50 via a connecting shaft 108. The rear folding wall 98 has the other end in the width direction of the upper plate 102 rotatably connected to the rear end side of the left and right side wall portions 58 of the box body 46 via a connecting shaft 108. The other end in the width direction of 104 is connected to the rear end of the left and right side walls 84 of the tray 50 via a connecting shaft 108. Each connecting shaft 108 is arranged in a state where the axial direction is along the sheet width direction, and the upper plate 102 and the lower plate 104 are rotatable around each connecting shaft 108.

  As shown in FIG. 6, in the state in which the tray 50 is located at the lowered position, the front folding wall 98 has the lower plate 104 standing substantially vertically while the upper end portion of the upper plate 102 is higher than the hinge portion 106. The upper plate 102 is inclined so as to be positioned on the front side of the seat. Similarly, in the state in which the tray 50 is located at the lowered position, the rear folding wall 98 is such that the lower plate 104 stands substantially vertically while the upper end portion of the upper plate 102 is on the rear side of the seat with respect to the hinge portion 106. The upper plate 102 is inclined so as to be positioned. Therefore, when the tray 50 is raised to the raised position, the front and rear folding walls 98 are folded toward the inside of the tray 50, and when the tray 50 is lowered to the lowered position, the front and rear folding walls 98 are moved to the box body 46 and the tray. 50 to expand. In this unfolded state, the gap between the front wall portion 60 of the box body 46 and the front wall portion 80 of the tray 50 is closed by the front folding wall 98, and the rear wall portion 62 of the box body 46 and the tray 50 are closed. The gap between the rear wall portion 82 is closed by the rear folding wall 98 (see FIGS. 4 and 6).

  On the other hand, the left and right nets 100 are formed in a long shape by a deformable cloth material or the like, and are arranged in a state where the longitudinal direction is along the front-rear direction of the seat. The front end portion of the net 100 is locked to the sheet width direction end portion of the lower plate 104 in the front folding wall 98, and the rear end portion of the net 100 is connected to the lower plate 104 in the rear folding wall 98. Locked to the end in the sheet width direction. Further, the lower end portion of the net 100 is locked to the side wall portion 84 of the tray 50. These nets 100 are folded toward the inside of the tray 50 when the tray 50 is raised to the raised position, and are expanded between the front and rear lower plates 104 when the tray 50 is lowered to the lowered position. In this unfolded state, the lower side of the gap between the left and right side wall portions 58 of the tray 50 and the left and right side wall portions 58 of the box body 46 is closed by the left and right nets 100.

<Action and effect>
Next, the operation and effect of this embodiment will be described.

  In the vehicle seat 10 having the above configuration, when the tip-up lever 40 is operated in the state shown in FIG. 1, the operating force of the tip-up lever 40 is locked via the common cable 38 and the tip-up cable 34. Transmitted to the latch 32 of the mechanism, the latch 32 is rotated to the unlocked position. When the latch 32 is rotated to the unlock position, the restraint of the seat cushion 12 by the latch 32 is released, and the seat cushion 12 is flipped up to the tip-up position by the biasing force of the spring (see FIGS. 2 and 3). .

  At this time, the operating force of the tip-up lever 40 is transmitted to the latch 72 of the cargo box locking mechanism 70 via the common cable 38 and the cargo box cable 76, and the latch 72 is rotated to the unlock position. When the latch 72 is rotated to the unlock position, the restraint of the box body 46 by the latch 72 is released, and the box body 46 is slid to the use position by the biasing force of the spring. Thereby, the cargo box 18 appears outside the front cover 24 (see FIG. 2).

  When the box body 46 is slid to the use position, the tray 50 connected to the box body 46 via the link mechanism 48 is moved to a lowered position that is spaced downward with respect to the box body 46 (see FIG. 3). Thereby, since the volume of the cargo box 18 increases, it becomes possible to place a larger load in the cargo box 18. Therefore, according to the present embodiment, even a large baggage that could conventionally be placed only on the seat cushion 12 or the vehicle body floor portion can be held by the cargo box 18, and the baggage when the vehicle is running Can be prevented from rolling and scattering. Therefore, the convenience of the cargo box 18 can be greatly improved.

  In addition, in the present embodiment, the cargo box 18 operates in conjunction with the tip-up of the seat cushion 12, and therefore the luggage compartment can be operated by one operation of tip-up (operation of the tip-up lever 40). Therefore, the operability can be improved as compared with the case where the chip up and the operation of the cargo box 18 must be operated separately. In addition, when the tip up and the cargo box 18 must be operated with both hands, it is necessary to place the luggage on the floor of the vehicle body. However, in this embodiment, the occupant holds the tip up lever 40 with one hand. Since it can be operated, it is possible to save the trouble of placing luggage. Furthermore, since the space above the cargo box 18 is expanded by tip-up of the seat cushion 12, it is possible to easily take in and out the cargo to the cargo box 18 and to further improve convenience.

  In this embodiment, the interlocking mechanism 68 for interlocking the tip up of the seat cushion 12 and the operation of the cargo box 18 uses the operating force of the tip up lever 40 for tipping up the seat cushion 12 as the common cable 38. Then, the signal is transmitted to the cargo box lock mechanism 70 via the cargo box cable 76. Thereby, the restraint of the box body 46 in the storage position is released, and the box body 46 is moved from the storage position to the use position by the biasing force of the spring. Therefore, the shared cable 38 and the tip-up lever 40 can be shared with the tip-up mechanism 30 and the interlocking mechanism can be established with a simple configuration.

  Furthermore, in the present embodiment, when the cargo box 18 is deployed, the tray 50 is supported on the floor of the vehicle body by the bottom wall portion 78 of the tray 50 coming into contact with the floor mat. For this reason, even when a heavy load is put in the cargo box 18, the weight of the load can be supported by the vehicle body floor portion via the tray 50. Thereby, since the rigidity of the cargo box 18 can be reduced, the weight reduction and cost reduction of the cargo box 18 can be achieved.
