Then, the second rear seat 7B is moved to the front of the vehicle body 8 by the moving mechanism 2 so that a part of the second rear seat 7B passes above the first rear seat 7A. Let

  Next, in the second mounting step, as shown in FIG. 12, the second rear seat 7 </ b> B gripped by the gripping portion 22 is moved to the outside in the left-right direction W of the automobile body 8 by the moving mechanism 2. Next, as shown in FIG. 13, when the jump arm 4 is moved to the retracted position 401, the seat leg 73 of the second rear seat 7 </ b> B is lifted from the original position by the spring biasing force. Return to state. Thereafter, as shown in FIG. 14, the second rear seat 7 </ b> B is moved below the automobile body 8 by the moving mechanism 2, and the second rear seat 7 </ b> B is mounted in the room 82 of the automobile body 8.

Next, the effect by the sheet | seat mounting apparatus 1 and the sheet | seat mounting method of this example is demonstrated.
In this example, when the second rear seat 7B is mounted in the room 82 while the first rear seat 7A is mounted in the room 82, the side of the second rear seat 7B Alternatively, the seat leg portion 73 of the second rear seat 7B is flipped up to a predetermined angle by the jumping mechanism 3 disposed above.
The contact portion 42 of the jumping arm portion 4 is changed to the second rear portion by the configuration of the jumping mechanism 3 including the rail member 51 and the link member 52 as the guide portion 5, the moving member 62, the constant velocity joint 61 and the like. The seat leg portion 73 can be flipped up by moving from a state positioned above the seat seat 7B to a state positioned below the second rear seat 7B.

By the way, in order to form the operation of retracting the raising arm portion 4 from the second rear seat 7B and the operation of raising the seat leg portion 73 by the raising arm portion 4, generally, These operations are performed separately using a driving source. However, when two drive sources are used, not only the overall weight of the jumping mechanism 3 increases, but it becomes difficult to retract one drive source from the second rear seat 7B.
In order to solve this problem, in the seat mounting apparatus 1 of the present example, the air cylinder 32 that is one drive source is used by using the rail member 51, the link member 52, the moving member 62, the constant velocity joint 61, and the like. The retraction operation and the jumping operation can be realized only by the thrust in the sliding direction S. Therefore, the number of drive sources can be reduced and the raising mechanism 3 can be formed compactly.

Further, the torsion generated between the jumping arm part 4 and the slider 332, which is generated when the jumping arm part 4 is rotated in the two rotation directions of the retraction operation and the jumping operation, is constant velocity joint. It can be absorbed by using 61. In the jumping mechanism 3, the jumping arm unit 4 performs the first trajectory X1 rotating between the retracted position 401 and the intermediate position 402 in order to realize the retracting operation, and the jumping operation. In order to achieve this, it is possible to smoothly form the second track X2 that rotates between the intermediate position 402 and the jumping position 403.
Further, by passing a part of the second rear seat 7B mounted in the room 82 from behind, the second rear seat 7B is passed over the first rear seat 7A previously mounted in the room 82. The work sheet 7B can be inserted into the rear opening 81 as low as possible. Therefore, it is possible to prevent the grip portion 22 or the lifting mechanism 3 that grips the second rear seat 7B from interfering with the upper side portion of the rear opening 81.

In addition, after the second rear seat 7B is inserted into the room 82 from the rear opening 81, an obstacle when the second rear seat 7B is installed in the room 82 by the operation of the jumping mechanism 3. The jump arm 4 can be easily retracted to a position where it does not become.
Therefore, according to the seat mounting apparatus 1 and the seat mounting method of the present example, the flip-up mechanism 3 is formed compactly, and the rear seats 7A and 7B having the seat leg portions 73 can be smoothly mounted on the vehicle body 8. Can be done.
