Is the wedge that is in contact.

When the door is closed, the striker 30 engages with the engagement groove 33 of the latch 31 to rotate the latch 31 forward.
( Leftward in FIG. 2) , and the half-latch engagement step 35
The half-latch position where the pawl 34 of the ratchet 32 is engaged is shown in FIG. 3 (FIG. 3) . Then, the short piece 4 of the operating arm 29
2 presses the switch terminal 43a of the switch 43 from the side to energize the drive motor 5 to rotate the passive gear 2 via the drive gear 8 and the engagement tooth portion 9; 10 and the clutch engaging recess 11 rotate the sliding rotating piece 3, and the front rotating roller 20 engages with the long hole 28 to rotate the fixed rotating piece 4.
Is rotated, the other end 27 of the fixed rotating piece 4 pushes the roller 41 of the long piece 40 of the operating arm 29 to rotate the latch 31 to the full latch position .

The fail-safe lever 6 is connected to the rotating shaft 4.
7, the shaft is fixed to the fixing metal bracket 1. The fail-safe lever 6 is substantially T-shaped, and a rod 49 extending to the outer handle or inner handle for the back door 57 is attached to the tip of a right piece 48 extending rightward from the rotation shaft 47, and extends leftward. An arc 51 is formed on the lower surface of the left piece 50. The arc portion 51 is an arc that approaches the central axis 22 of the passive gear 2 as approaching the rotation shaft 47. At the lower end of the hanging piece 52 of the fail-safe lever 6 extending below the rotation shaft 47, a hook 54 facing the projection 53 of the ratchet 32 is attached. The hook 54
Is provided with a long hole 55 in the longitudinal direction, and a protrusion 56 protruding from the bracket 1 is engaged with the long hole 55.

[0013]

Next, the operation will be described. (Normal Operation) When the door is closed, the striker 30 is engaged with the engagement groove 33 of the latch 31.
The latch 31 engages by left rotation in Fig. 2, the pawl 34 of the ratchet 32 in the half-latch engagement Godan unit 35 is in the half latched position as shown in FIG. 3 engage the. Then,
Operation that rotates together with the latch 31 about the latches shaft 37
The short piece 42 of the arm 29 is the switch terminal 4 of the switch 43.
Press 3a to energize the drive motor 5. When the drive motor 5 is energized, the drive gear 8 rotates, and the passive gear 2 rotates due to the engagement between the drive gear 8 and the engagement tooth portion 9.
Pin 1 engaged with the clutch engaging recess 11
0, the sliding and rotating piece 3 is centered on the central shaft 22 in FIG.
Then, the fixed rotation piece 4 is rotated clockwise by engagement of the clutch pin 10 and the elongated hole 28.

[0014] fixed turning piece 4 rotates clockwise, from hitting roller 41 of the operating arm 29 at the other end (lower end) 27 of the fixed pivot member 4, the actuating arm 29 rotates counterclockwise in FIG. 3, hydraulic
Arm 29 is left rolling latch 31 via the connecting shaft 39, the fully latched latch 31 as shown in FIG. 4 in motor power
Position .

When the latch is fully latched, the roller 17 of the sliding rotation piece 3 is moved by the arc 5 of the left piece 50 of the fail-safe lever 6.
1 is joined to a portion close to the rotation shaft 47. This part is axis 2
2, the roller 17 is pushed, and the sliding and rotating piece 3 is moved downward against the elasticity of the reduction spring 26. Release and the full latch is complete.

(Emergency Operation) A half latch state (FIG. 3) in which the pawl 34 of the ratchet 32 is engaged with the half latch engaging step 35, or the pawl 34 of the ratchet 32 is engaged with the full latch engaging step 36 in either engaged fully-latched state (FIG. 4), the back door 57
Pinch a more hands on, there is a time of emergency to pinch things. At that time, open the inner or inner handle . Then, the fail-safe lever 6 rotates counterclockwise in FIG. 1 via the rod 49, and presses the roller 17 with the arc portion 51, so that the sliding rotation piece 3 descends and the engagement between the clutch engagement recess 11 and the clutch pin 10 is reduced. If this is the case,
As a result, the connection state between the passive gear 2 and the sliding rotation piece 3 is released,
It is possible to stop the rotation of the latch 31 by the motor power.
I can .

Further , when the handle is opened, a failure occurs.
When the safe lever 6 rotates to the left in FIG. 1, the hanging piece 52 extending downward from the rotation shaft 47 simultaneously moves rightward, so that the hook rod 54 facing the projection 53 of the ratchet 32 is moved, and the hook rod 54 projects. the piece 53 is moved off from the half-latch engagement Godan unit 35 or the full-latch engagement Godan portion 36 a pawl 34 of the ratchet 32, thereby opening the door.

[0018]

According to the above-mentioned known automatic closer, in the event of an emergency in which a hand or an object is pinched, the outer or inner handle can be opened to operate the door.
It had been configured to interrupt the lock, the known ones, merely interrupting the closing by motor, of suspended
I couldn't open the door.

However, according to the present invention, the back door 5 of a vehicle is provided.
