Next, when the slide door 3 is closed and the rear lock 31b engages and locks the striker 10d and locks, the connecting rod 34c is pushed out in the direction of the arrow Y2 in conjunction with this, whereby the link lever 48 moves the support shaft 480. The pivot lever 45 and the hook member 44B pivot in the direction of the arrow Y3 around the center, interlocking with the pivot of the link lever 48, and integrally pivot in the direction of the arrow X3 against the urging force to the coupling position. Operate. When the hook member 44B and the rotation lever 45 reach the connection position, the engaging claw 47 of the latch lever 46 engages with the tip corner of the rotation lever 45 to move the hook member 44B and the rotation lever 45 to the connection position. Let me keep. At this time, the hook member 44B and the projecting piece 42 of the base member 40B form the above-mentioned annular portion in the lateral direction.
[0027]
When the door handle 32 is operated to open the slide door 3, the remote control mechanism 33 is operated, and the connection wire 34 d is pulled in the direction of the arrow Z <b> 2 in conjunction with the operation, and the latch lever 46 is pulled by the connection wire 34 d. It turns in the direction opposite to the arrow X4 against the urging force. As a result, the engagement between the rotating lever 45 and the engaging claw 47 is released, and the hook member 44B and the rotating lever 45 are rotated from the connection position in the direction of arrow X3 by the urging force to the open position.
[0028]
The engagement operation of the first and second connecting means 4A, 4B when the hinge door 2 and the slide door 3 are closed will be described. For example, when the slide door 3 is closed while the hinge door 2 is closed, as shown in FIGS. 2A and 2B, on the hinge door 2 side, the hook member 44A of the first connection means 4A operates to the connection position. The hook member 44A and the protruding piece 42 of the base member 40A form a vertical annular portion. On the other hand, when the slide door 3 is open, the second connecting means 4B is housed in the slide door 3 with the hook member 44B in the open position (shown by a chain line in the figure).
[0029]
When the sliding door 3 is slid in the direction of the white arrow to close the door 3, the projecting piece 42 of the base member 40B of the second connecting means 4B interferes with the projecting piece 42 of the first connecting means 4A. Instead, it is a position adjacent to the outside of the vehicle and upward, and the opening between the base end and the front end of the hook member 44B is a position facing the rear end side of the hook member 44A forward and backward. Then, when the rear lock 31b of the slide door 3 is locked, the link lever 48 and the rotation lever 45 of the second connecting means 4B are operated in conjunction with the locking, and the hook member 44B connects the tip thereof to the first connecting means 4A. It operates to the connecting position while being inserted into the vertical annular portion, and the annular portions of the first and second connecting means 4A, 4B engage in a vertical and horizontal chain shape without contacting each other.
[0030]
In the event of a side collision of the vehicle, even if the hinge door 2 and the slide door 3 flex and deform toward each other due to the impact, and the two doors 2 and 3 are opened, the hook member 44A of the first connection means 4A and the second connection means The hook members 44B of the 4B abut against each other and are pulled together, thereby suppressing deformation of the doors 2 and 3 inside the vehicle and preventing the doors 2 and 3 from opening. Even if the impact of the collision is large and a large load acts on both hook members 44A and 44B, the two hook members 44A and 44B pull each other, and the curved shape of both of them expands and deforms. Since the hook 441 at the tip of each hook member 44A, 44B inserted into the 420 engages with the opening edge of each through hole 420, the extension deformation of each hook member 44A, 44B is suppressed, and each annular portion does not collapse. Opening of both doors 2 and 3 can be reliably prevented.
[0031]
The first and second connecting mechanisms 4A, 4B are adapted to operate the hook members 44A, 44B to the connecting position in conjunction with the lock mechanisms 21b, 31b of the doors 2, 3 on which they are installed. Therefore, it is possible to close the hinge door 2 with the slide door 3 closed. In this case, on the side of the slide door 3 in the closed state, the hook member 44B of the second connecting means 4B is at the connecting position, and forms a horizontal annular portion with the protruding piece 42. When the hinge door 2 is closed, the hook member 44A and the protruding piece 42 of the first connecting means 4A in the open position vertically oppose the annular portion of the second connecting means 4B, and the hinge door 2 is moved. By being locked, the hook member 44A operates to the connecting position while inserting its tip into the annular portion of the second connecting means 4B, and the annular portions of the first and second connecting means 4A, 4B are engaged. I do.
[0032]
The first and second connecting mechanisms 4A and 4B operate the hook members 44A and 44B from the connecting position to the open position in conjunction with the door handles 22 and 32 of the doors 2 and 3 on which the first and second connecting mechanisms are installed. The first and second connecting mechanisms 4A and 4B can be disengaged by opening the door handles 22 and 32 of one of the doors 2 and 3. For example, when the door handle 22 of the hinge door 2 is operated, the hook member 44A of the first connecting means 4A is operated to the open position in conjunction therewith, and its annular portion is opened to allow the hook member 44A to engage with the annular portion of the second connecting means. The engagement can be released and the hinge door 2 can be opened. On the other hand, when the door handle 32 of the slide door 3 is operated, the hook member 44B of the second connecting means 4B is operated to the open position to release the engagement of the first and second connecting means 4A, 4B, and the slide is performed. The door 3 can be opened.
[0033]
