  As shown in FIG. 2B, the seat back 62 and the seat cushion 61 are moved toward the bottom plate 33 of the luggage compartment 32 as indicated by an arrow d while the seat back 62 is tilted to the seat cushion 61.

  As shown in FIG. 2C, the seat back 62 and the seat cushion 61 are accommodated in the luggage compartment 32. The back leg 75 is in a state of being brought down. In addition, the seat back 62 and the seat cushion 61 can be raised and brought into an upright state by performing the steps described above in reverse.

Next, the support part 73, the leg part 75, and the leg part cover 91 are demonstrated.
As shown in FIGS. 4 to 6, the leg cover 91 is made of resin and includes a front-side front half 92 and a back-side rear half 93. The front half 92 and the back half 93 are formed so as to extend along the rear leg 75. The rear half body 93 is longer than the front half body 92 and is formed so as to cover from the vicinity of the lower surface of the seat cushion 61 (see FIG. 3) to the side of the support portion 73 provided on the bottom plate 33. For this reason, the external appearance of the leg part 75 from the luggage compartment 32 side can be improved more.

  The rear half 93 includes a rear surface portion 94 formed on the vehicle rear side along the vehicle width direction, side surface portions 95 and 95 formed to extend forward from both ends of the rear surface portion 94 in the vehicle width direction, and a rear surface. The lower end portion of the portion 94 has a notch portion 96 formed so as to avoid the support portion 73. The cutout portion 96 can prevent the back surface portion 94 from interfering with the support portion 74 even if the leg portion 75 is tilted backward.

  The side surface portion 95 of the leg portion cover 91 covers up to the side of the first shaft 74 provided on the support portion 73. Since the 1st axis | shaft 74 is covered with the side part 95, the external appearance property from a vehicle width direction can be improved.

  A protrusion 98 that protrudes toward the inside of the leg 75 is formed at the end 97 on the support 73 side in the rear half 93 of the leg cover 91. A gap between the lower surface (lower end) 75 a on the back side of the leg portion 75 and the support portion 73 is narrowed by the protruding portion 98. The protrusion 98 is formed over the entire vehicle width direction of the notch 96, and the width of the protrusion 98 in the vehicle width direction is equal to or equal to the width of the support 73 in the vehicle width direction. It is slightly larger than the width of 73 in the vehicle width direction.

  Even if the leg part 75 is tilted by the projection part 98, it is possible to prevent foreign matter from entering between the leg part 75 and the support part 73. For this reason, when the leg portion 75 is tilted, the right seat 22 in the third row (see FIG. 3) can be smoothly folded or raised without being pressed by hand so that no foreign matter enters. Further, since only the plate-like protrusion 98 is formed on the end portion 97 on the support portion 73 side in the leg cover 91, the molding is easy, and the component cost can be reduced.

  A lower surface 75 a of a portion of the leg portion 75 that is covered with the leg portion cover 75 is in contact with the protruding portion 98. Even if a foreign object tries to enter the gap between the leg portion 75 and the support portion 73 and the projection portion 98 receives a pressing force due to the foreign matter, the projection portion 98 is supported by the lower surface 75a of the leg portion 75. The deformation of 98 can be prevented, and entry of foreign matter can be prevented.

  The support portion 73 is covered with a support portion cover 101 from the rear portion to the upper portion. The upper surface 73a of the support portion 73 is formed in an arc shape so as to follow the trajectory of the protrusion 98 rotating. The upper surface 101a of the support portion cover 101 is formed in an arc shape so as to follow the trajectory of the protrusion 98 rotating.

  For this reason, as shown in FIG. 6, even if the leg portion 75 indicated by the solid line is rotated to the position of the leg portion 75 indicated by the imaginary line, the upper surface 73a of the support portion 73 and the upper surface 101a of the support portion cover 101 The gap between the protrusion 98 and the tip can be kept small, and foreign matter can be prevented from entering regardless of the pivot position of the leg 75.

  As shown in FIG. 7, the right seats 22 in the third row are folded and stored in the luggage compartment 32. The leg portion 75 is turned down and disposed along the bottom plate 33. Since the protruding portion 98 protrudes toward the inside of the leg portion 75, it does not protrude into the luggage compartment 32. Even if there is a cloth foreign matter on the bottom plate 33 of the luggage compartment 32, it will not be caught by the protrusion 98. For this reason, even if the right seat 22 in the third row is raised, the foreign matter does not enter the gap between the leg portion 75 and the support portion 73.

  In the embodiment, the support portion 73, the leg portion 75, and the leg portion cover 91 of the right seat 22 in the third row have been described. However, the present invention is not limited to this, and the support portion 73 and the leg portion of the left seat in the third row. 75 and the leg cover 91 have the same configuration and action. In the embodiment, the third row sheet has been described. However, if a protrusion protruding toward the inside of the leg portion is provided at the end portion on the support portion side in the leg portion cover, the first row seat is provided. It does not matter whether the sheet is in the row, the second row, or the left and right.

  In the embodiment, the seat structure in which the leg portion of the seat is tilted rearward of the vehicle has been described. However, the present invention is not limited to this. In this case, it is possible to prevent foreign matter from entering the gap between the support portion and the leg portion when the leg portion is rotated backward from the state where the leg portion has fallen forward.

  Further, in the embodiment, the leg portion is provided at a recessed position like the cargo compartment 32, but the present invention is not limited to this, and the leg portion 75 is rotatably provided on the floor 31 and provided higher than the floor 31. There is no problem even if the lock portion 78 is engaged with the striker 36. In other words, the embodiments are merely examples of the present invention, and the present invention is not limited to these types as long as the operations and effects are achieved.

  The present invention is suitable for a seat structure in which the seat is folded by tilting the leg portion of the seat.
