The contact piece 73 does not engage with the protrusion 17 and cannot open the door.

[0022]

[Operation] Next, the operation will be described. In the open state shown in FIGS. 2 and 6, when the door A is closed gently without applying much force, the striker 2 provided on the vehicle body B side slowly opens the door A.
The latch 6 is engaged with the engaging groove 18 of the side latch 6 to rotate the latch 6 to the half-latch position. Then, the abutment with the latch 6 causes the rotor 23 to rotate and press the actuating piece 24 to turn on the half-latch switch 20, whereby the actuator 25 is actuated to wind the wire 43, and the fan-shaped lever 38. Rotate counterclockwise in FIG.

When the fan-shaped lever 38 rotates, the pin 6 is inserted into the radial hole 47 of the fan-shaped lever 38 and the elongated hole 50 of the rotary lever 49.
Since 4 is engaged, the rotating lever 49 also rotates in conjunction with it, and the interlocking lever 28 also rotates clockwise in FIG. 2 via the rotating shaft 27 fixed to the rotating lever 49. As a result, the roller 35 of the slide member 30 moves from the right side to the left side along the guide groove 36, and the arc groove 36 of the guide groove 36.
When it reaches the right end of a, the latch 6 in the half latch position
Abutting on the engaging leg portion 19 (see FIGS. 3 and 7).

When the actuator 25 further rotates and the fan-shaped lever 38 moves to the operation end position shown in FIG. 8, the roller 35 of the slide member 30 is guided by the arc groove 36a,
The latch 6 is rotated to the full-latch position shown in FIG. 4 without being disengaged from the engaging leg portion 19, and the pawl 13 of the ratchet 11 is engaged with the full-engaging step portion 15 of the latch 6 to complete the closing of the door.

When the latch 6 reaches the full-latch position, the operating piece 22 of the full-latch switch 21 is pressed by the latch 6 to be turned on, whereby the energization of the actuator 25 is stopped and the fan-shaped lever 38 at the operation end position is spring-loaded. It is returned to the standby position shown in FIG. 6 again by the elasticity (not shown).

During the above series of operations, the door A is closed.
When an unexpected situation occurs such as when your hand is caught in your hand, it is necessary to immediately stop the forced door closing by the actuator 25. In the present invention, as a countermeasure against this, when the open handles 56 and 60 inside and outside the door are operated, the actuator 2
The power transmission mechanism 29 from 5 to the interlocking lever 28 can be cut off, and the door A can be opened. This will be described in detail below.

As described above, when the latch 6 is in the half-latch position and the actuator 25 is operating, the outer open handle 56 or the inner open handle 60 of the door is operated to rotate the open lever 51. As shown in FIG. 7, the shaft 62, which was located on the same axis as the rotary shaft 27, is displaced as shown in FIG. 9, and the pin 64 of the moving rod 63 is moved from the radial hole 47 of the fan-shaped lever 38. It moves to a position facing the arc hole 46. As a result, the engagement between the pin 64 and the fan-shaped lever 38 is released, and even if the fan-shaped lever 38 rotates, the pin 64 only moves within the arc hole 46.
The rotational force of the fan-shaped lever 38 is not transmitted to the pin 64. Therefore, thereafter, only the fan-shaped lever 38 rotates, and the rotating lever 49 and the interlocking lever 28 do not rotate (tenth position).
Figure). At the same time, when the open lever 51 rotates, the vertical link 66 connected by the shaft 65 moves downward, and the contact piece 73 pushes down the protrusion 17 of the ratchet 11, so that the pawl 13 of the ratchet 11 latches. 6 is separated from the half engagement stepped portion 14, the latch 6 is free, and the door is opened.

Therefore, the slide member 30 is the roller 3
5, the engaging leg portion 19 of the latch 6 is pushed and moved, so that no unreasonable force acts on the latch 6 and the latch member 6 operates smoothly, and the plate 31 of the slide member 30 is made of a thin metal plate. Even if formed, it can withstand a large load.

In the closed state, the latch 6 is in the full latch position in FIG. 4, the slide member 30 is in the standby position in FIG. 2, and the roller 35 of the slide member 30 is from the rotation locus of the engaging leg portion 19 of the latch 6. Since they are separated from each other, even if the latch 6 is released by the door opening operation, the engaging leg portion 19 and the roller 3
5 do not interfere with each other, and the latch 6 can be smoothly rotated toward the open position by the elasticity of the spring 10.

Further, in the present invention, the door A in the state shown in FIG.
When the force is closed, the striker 2 engages with the engagement groove 18 of the latch 6, and the force of the actuator 25 is used to rotate the latch 6 to the full latch position shown in FIG. You can also close the door without it. As a result, even if the actuator 25 fails, the vehicle can be driven without any trouble.

In the above description of the embodiment and the operation, the rotating lever 49 is fixed to the rotating shaft 27, but the rotating lever 49 is substantially an integral part of the interlocking lever 28 and is long. A hole 50 is formed in the interlocking lever 28, and the long hole 50 and the hole 48 of the fan-shaped lever 38 are connected to the pin 6 of the moving rod 63.
It is also possible to omit the rotary lever 49 by inserting 4 into the rotary lever 49.
