Thereby, the rotation of the left and right links 48 and 50 in the direction of the arrow R2 in FIG. 4 is restricted. In this state, the weight of the seat body 16 acts to press the left and right links 48 and 50 against the second stopper portion. Accordingly, inadvertent rotation of the left and right links 48 and 50 in the direction of the arrow R2 in FIG. 4 is restricted, and the seat body 16 is held in the flip-up position. Then, when the leg portion 30 of the seat cushion 24 is rotated to the storage position as shown in FIG. 4, the storage of the seat body 16 is completed. Note that a lock mechanism that restricts the rotation of the left and right links 48 and 50 in a state where the seat body 16 is in the flip-up position may be provided in the front and rear connecting portions 32A of the seat cushion 24 and the like.

  In the state in which the seat body 16 is flipped up as described above (the flip-up state), the left and right links 48 and 50 are in a posture extending from the left and right connection brackets 52 and 54 to the vehicle upper side and the vehicle width direction inward. The shaft 62 is disposed on the vehicle upper side and the vehicle width direction inner side with respect to the connecting shaft 60. Further, in this flip-up state, the seat cushion 24 is arranged on the inner side in the vehicle width direction with respect to the seat back 26, and the bottom surface of the seat cushion 24 is configured to face the driver's seat 14 side. Further, in this flip-up state, the seat body 16 is disposed so as to be offset outward in the vehicle width direction with respect to the center between the left and right slide rails 18 (see the alternate long and short dash line CL in FIG. 4). It is comprised so that it may be arrange | positioned below the side mirror 66 (refer FIG. 1) of the side.

  In the present embodiment, the front / rear position of the seat body 16 can be adjusted by the left and right slide rails 18 in both the normal state and the flip-up state described above.

(Function and effect)
Next, the operation and effect of this embodiment will be described.

  In the vehicle seat 10 having the above-described configuration, the front and rear slide members 20 are bridged between the left and right slide rails 18 in which the seat cushion 24 of the seat body 16 is slidably connected to the vehicle body floor portion 44 in the front-rear direction of the seat. ing. Front and rear link mechanisms 46 constituting the side flip-up mechanism 22 are attached to these slide members 20. These link mechanisms 46 are connected to the seat cushion 24 so that the seat body 16 in a state in which the seat back 26 is tilted forward on the seat cushion 24 can be flipped up to a sideways posture.

  As described above, in this embodiment, the front and rear slide members spanned between the left and right slide rails 18 are the side flip-up mechanism 22 (the front and rear link mechanism 46) for jumping the seat body 16 to the sideways posture. 20 is attached. Thereby, even if the seat body 16 is arranged on the side of the front side door 15, the side flip-up mechanism 22 can be installed independently of the front side door 15. Side-up storage is possible. Moreover, since the front and rear slide members 20 are fixed to the upper rails 38 of the left and right slide rails 18, the front and rear positions of the seat body 16 can be adjusted by the left and right slide rails 18, and the seat body 16 can be flipped up sideways. It is possible to balance storage.

  Further, in this embodiment, the front and rear link mechanisms 46 constituting the side flipping mechanism 22 have a pair of left and right links 48 and 50. The left and right links 48 and 50 are arranged side by side in the seat width direction, and both ends in the longitudinal direction can rotate about the axis in the front-rear direction of the seat with respect to the slide frame 20 and the cushion frame 32 of the seat cushion 24, respectively. It is connected to. As these links 48 and 50 rotate with respect to the slide member 20 and the seat cushion 24, the seat body 16 is guided to be flipped up. Moreover, the flip-up position of the seat body 16 can be adjusted (changed in setting) by setting the connection positions of the left and right links 48, 50 with respect to the slide member 20 and the seat cushion 24, the dimensions of the left and right links 48, 50, and the like. Therefore, the degree of freedom in setting the flip-up position of the seat body 16 can be improved.

  For example, as in the present embodiment, the flip-up position of the seat body 16 can be set low so that the seat body 16 that is flipped up is disposed below the side mirror 66 on the passenger seat side. . As a result, as shown in FIG. 1, the seat body 16 that is flipped up can be prevented from obstructing the side view (see the one-dot chain line SV in FIG. 1) on the passenger seat side of the driver D. .

  Further, in the present embodiment, when the seat body 16 is flipped up, the left and right links 48 and 50 are turned inward in the vehicle width direction, whereby the connecting portion 32A of the seat body 16 is inward in the vehicle width direction (the seat body 16). Is displaced to the side opposite to the side from which the spring is raised. Thereby, it can prevent by the simple structure that the sheet | seat main body 16 bounced up interferes with the front side door 15. FIG. Moreover, since the passenger who raises the seat body 16 only needs to lift the side of the seat body 16 on the inner side in the vehicle width direction, the raising operation is easy.

  In the present embodiment, in a state where the seat body 16 is flipped up, the seat body 16 is arranged to be offset outward in the vehicle width direction with respect to the center CL (see FIG. 4) between the left and right slide rails 18. . Thereby, a space such as a walk-through space (see an arrow WT in FIG. 5) in which a passenger can move between the seat body 16 that is flipped up and the driver's seat 14 or a bag 68 (see FIG. 6). A multi-space can be formed for placing. Thereby, a passenger | crew's convenience can be improved (In addition, the code | symbol 70 is attached | subjected to the rear seat of the vehicle 11 in FIG.5 and FIG.6).

  In particular, in a light vehicle having a limited size in the vehicle width direction, the walk-through between the rear seat 70 and the driver's seat 14 that is employed in a small vehicle or the like cannot be employed. According to this, even in a light vehicle, a walk-through between the rear seat 70 and the driver's seat 14 is possible. Thereby, the convenience in case a mother etc. use a child seat on a rainy day can be improved, for example. In other words, in a conventional light vehicle that cannot be walk-through, a mother or the like may head for the driver's seat 14 after having a child seated in a child seat (not shown) attached to the rear seat 70 if the child does not go out of the vehicle. It can't be done, so it gets wet in the rain. In this regard, in the present embodiment, the driver's seat 14 and the rear seat 70 can be moved back and forth without going out of the vehicle.

  Furthermore, in the present embodiment, when the seat body 16 is flipped up, the side portion on the inner side in the vehicle width direction of the seat body 16 is lifted upward. Thereby, the operativity at the time of performing the flip-up operation of the seat body 16 from the driver's seat 14 side can be improved. Further, when the seat body 16 is flipped up, the seat cushion 24 is disposed on the inner side in the vehicle width direction with respect to the seat back 26, and the bottom surface of the seat cushion 24 faces the driver's seat 14 side. Thereby, the operativity at the time of folding the leg part 30 from the driver's seat 14 side can be made favorable.

  In the first embodiment, the side of the seat body 16 on the inner side in the vehicle width direction is lifted upward when the seat body 16 is flipped up. However, the present invention is not limited to this. Absent. That is, like the vehicle seat 80 (modified example) shown in FIGS. 7A to 7C, when the seat body 16 is flipped up, the side portion on the outer side in the vehicle width direction of the seat body 16 is lifted upward in the vehicle. It may be configured. In the vehicle seat 80, the side flip-up mechanism 22, the legs 30, and the striker 42 are arranged and structured symmetrically with respect to the vehicle seat 10 according to the first embodiment. Other configurations are the same as those in the first embodiment.

  In the vehicle seat 80, the seat cushion 24 is disposed on the outer side in the vehicle width direction with respect to the seat back 26 when the seat body 16 is flipped up, so that the bottom surface of the seat cushion 24 is not exposed to the driver's seat 14 side. Can be. Accordingly, the setting of the cover member for improving the appearance of the bottom surface of the seat cushion 24 and the configuration for satisfying the so-called in-collision requirement (safety standard for vehicle interior parts: ECE21) are unnecessary, which is preferable. .

  Further, in the first embodiment, the seat body 16 that is flipped up is arranged to be offset toward the outside in the vehicle width direction with respect to the center CL between the left and right slide rails 18. It is not limited. In other words, the seat body 16 that is flipped up may be configured to be offset toward the inner side in the vehicle width direction with respect to the center CL between the left and right slide rails 18. The arrangement of can be changed as appropriate.
