  FIG. 6D shows that the first door is highly rigid against an impact from the side surface of the door 5 as in the Model 1612c.

  FIG. 9 is a diagram for explaining the operation of Model 1622c. Model 1622c is a long rear door that opens and closes by rotating and translating in a different motion from Model 1612c. Fig. 9 (a) shows the closed first door, Fig. 9 (b) The state of the second door in which only the front-rear range of the front seat 2 is opened, and FIG. 9C shows the state of the third door in which the front-rear range of the front seat 2 and the rear seat 3 are opened. . Although an example of the operation for opening the door 5 is shown, the operation for closing the door 5 and the operation for opening the door 5 are performed in reverse.

The detailed operation of Model 1622c will be described with reference to FIGS.
In the state of the first door, the lock pin (third fixing means) 266 and the lock pin hole (third fixing means) 267 fix the second link 231 and the door side bracket 210 in the vertical direction. The three rotary actuator 242 fixes the second link 231 and the door side bracket 210 in the horizontal direction.

  In the transition from the first door state to the second door state, the first rotary actuator 240 rotates the first link 230, and the second rotary actuator 241 moves the second link and the door side bracket 210 to the first rotary. It rotates in the opposite direction to the actuator 241.

In the state of the second door, the lock pin (third fixing means) 266 and the lock pin hole (third fixing means) 267 fix the second link 231 and the door side bracket 210 in the vertical direction. The three rotary actuator 242 fixes the second link 231 and the door-side bracket 210 in the horizontal direction, and the first link 230 holds the second link 231 and the door-side bracket 210.
In the state of the second door, a stress to be applied to the door 5 is a torsional moment B 284 having a rotation axis at a position where the door 5 is supported by the first link 230. The distance from the rotating shaft to the open end of the door 5 where the force is applied is 3/4 of the length of the door 5, and the length of the first link 230 is about 1 / length of the length of the door 5. 4.
Compared to Model 1612c, Model 1622c is disadvantageous in terms of rigidity because the distance from the rotation axis to the end of the door 5 on the open side, which is a point where force is applied , is long. However, since the first link 230 rotates in the state of the second door, the rear seat occupant can get on and off more easily than the Model 1612c by sliding the front seat 2 forward. This is effective when there is no room in the rear and side spaces when parking and the state of the third door is difficult.

  In the transition from the second door state to the third door state, the second rotary actuator 241 rotates the second link 231, and the third rotary actuator 242 reverses the door-side bracket 210 with the second rotary actuator 241. Rotate in the direction. By rotating the third rotary actuator 242, the lock pin (third fixing means) 266 and the lock pin hole (third fixing means) 267 release the second link 231 and the door side bracket 210 in the vertical direction. To do.

In the state of the third door, the second link 231 and the door-side bracket 210 are in a state of facing and contacting each other at a position different from the state of the first door and the state of the second door, 260 and a lock pin hole (first fixing means) 261 fix the second link 231 and the door side bracket 210 in the vertical direction, and the third rotary actuator 242 includes the second link 231 and the door side bracket 210. Is fixed horizontally.
In the state of the third door, the stress to be applied to the door 5 is a torsional moment C 285 having a rotation axis at the position supported by the first link 230 of the door 5 as in the models 1611c and 1612c. Oh it is, a higher ability to support it even over the body weight at the end of the open side of the door 5 at the time of the occupant getting on and off in a state that opened the door 5.

  As for the improvement of the first fixing means and the third fixing means, the lock pin (first fixing means) 260 does not come off the lock pin hole (first fixing means) 261 in the same manner as Model 1611c and Model 1612c. In order to prevent the lock pin (third fixing means) 266 from being removed from the lock pin hole (third fixing means) 267, a horizontal fixing ability is obtained by using a mechanism that can be locked and released, such as a lock solenoid. Can be increased.

  As described above, it is shown that models other than Model 1611c, Model 1612c, and Model 1622c described in Embodiments 1, 2, and 3 can be described as Model 1611c, Model 1612c, and Model 1622c. The operation of Model 1621c can be explained by the operation of Model 1611c and Model 1622c. The operation of Model 1611a, Model 1612a, Model 1621a, Model 1622a is the second link compared to Model 1611c, Model 1612c, Model 1621c, Model 1622c Although the angles of 131a, 131b, 231 and the door 5 are different, the operation is the same. Therefore, all the models of Model 16 shown in FIG. 1 are described in Examples 1, 2, and 3.
