When the door 3 occupying the closed position is locked with respect to the vehicle body 2, the operation button 38 and the swing link 43
Etc. occupy the position shown by the solid line in FIG. here,
First and second door lock devices 1 to open door 3
To release the locks of the locks 8 and 19, for example, an operator outside the vehicle compartment presses the operation button 38 with the finger toward the vehicle compartment as shown by an arrow P, and the button 38 is pressed against the action of the spring 41, Slide in the direction of arrow P together with the pressure pin 42. As a result, the swing link 43 is pressed, and the link 43 rotates around the pivot pin 44 to the position shown by the chain line in FIG. Then, the transmission wire 46 is pulled upward, the transmission link 48 is pulled downward, and the operation button 38
Is transmitted to the first and second door lock devices 18 and 19, respectively. Thereby, each door lock device 1
The latches 8 and 19 are rotated, and the latches are disengaged from the strikers 22 and 23, respectively, and the door lock devices 18 and 1
9 is unlocked. The door 3 enters the free state. So, if you pull the door 3 backward as described above,
This can be brought to the open position. When the door 3 is returned to the closed position, the latches of the door lock devices 18 and 19 are automatically engaged with the strikers 22 and 23, respectively, and the door 3 is locked.

As described above, an inside handle (not shown) is provided on the inner panel 4 of the door 3, that is, the surface on the vehicle interior side. Is transmitted to the first and second door lock devices 18 and 19 via a transmission element (not shown), the lock is released, and the door 3 can be moved to the open position.

As described above, in this example, the operation buttons 38
And the inside handle constitute an operating member operated when unlocking a plurality of door lock devices so as to open the door, and the pressure pin 42 and the swing link 4 shown in FIG.
3. The operation of the transmission wire 46 and the transmission link 48 and the operation of the insid handle are controlled by the first and second door lock devices 1.
Transmission elements (not shown) that transmit the signals to the doors 8 and 19 constitute transmission means that transmits the operation of the operating member to the door lock devices. The operation member and the transmission means are both provided on the door 3. The automobile shown in FIG. 1 has such operating members and transmission means.

As can be seen from the above description, only by pressing one operation member, for example, the operation button 38,
All of the plurality of door lock devices 18 and 19 can be operated to release the lock. Therefore, the door lock releasing operation can be easily performed. However, on the other hand, since a plurality of door lock devices are operated by one operating member, a large force may have to be applied to the operating member. The operating force required to release the door lock becomes excessively large, and the operability is reduced. The door pivotally opened and closed with respect to the vehicle body is 1
Since the door lock device is locked to the vehicle body, the operating force when unlocking this door lock device is small, but in the case of a sliding door, multiple door lock devices Since the door is locked to the vehicle body, unlocking these door lock devices must be done by 1
If performed simultaneously by two operating members, an extremely large operating force is required, and the operability is impaired.

Therefore, in the vehicle of this embodiment, the operation buttons 38 shown in FIG.
Is pressed, a plurality of door lock devices 18, 19
Are not simultaneously performed, but are unlocked sequentially at a later time. The details are as follows.

The swing link 43 shown in FIG. 7 is pivotally supported by the inner panel 4 via the pivot pin 44 as described above. Here, the first arm 45 is moved from the center of the pivot pin 44. , The distance to the portion where the transmission wire 46 is locked is R1. Similarly, if the distance from the center of the pivot pin 44 to the tip of the second arm 47, that is, the portion where the transmission link 48 is pivotally connected is R2, then R1> R2. With such a configuration, the operation button 38 is pressed in the direction of the arrow P as described above, and the swing link 43 starts rotating from the initial position shown by the solid line, and at the time before this reaches the final position shown by the chain line, When the swing link 43 rotates by a predetermined angle θ, the amount of movement at the tip of the first arm 45 is larger than the amount of movement at the tip of the second arm 48. That is, when the swing link 43 rotates by an angle of θ, the transmission wire 46 is pulled a greater distance than the transmission link 48. For this reason,
While the operator presses the operation button 38, first, the latch of the first door lock device 18 is disengaged from the first striker 22 to release the lock, and after a certain time, the second door lock device 18 is released. The latch of the device 19 is released from the second striker 23 and its lock is released. For example, when the swing link 43 rotates by an angle of θ from the initial position of the solid line, the lock of the first door lock device 18 is released,
Further, when the swing link 43 reaches the final position shown by the chain line, the lock of the second door lock device 19 is released.

As described above, the plurality of door lock devices 1
8 and 19 perform the lock release operation with a time lag,
The operation force applied to the operation button 38 can be significantly reduced as compared with the case where the lock release operation is performed simultaneously. FIG. 8 is a graph showing one example, in which the horizontal axis indicates the amount of operation when the operation button 38 is pressed, and the vertical axis indicates the operation force applied to the operation button 38. Pushing the operation button 38, in accordance with the operation amount is increased, the operating force is also increased, at the operation amount indicated by S _1,
The operating force indicates the first peak P _1. This indicates that the first door lock device 18 has been unlocked. When the operation button 38 is further depressed after the lock is released, the operation force temporarily decreases and increases again.
Then, at the operation amount indicated by S _2, the unlocking of the second door lock device 19 is performed, the operation force at this time is the second
Shows a peak P _2.

In the present embodiment, the center of rotation of the swing link 43 is
Distance R between the connecting point of the operating wire 46 and the transmission link 48
1, R2, that is, by changing the lever ratio, the lock release timing of each door lock device 18, 19 is regulated, and the swing link 43 and the setting of the lever ratio operate one operation member. At this time, the timing control means for regulating the lock release timing of each door lock device is configured so that the unlocking of the plurality of door lock devices is performed sequentially at a later time.

As described above, in the present embodiment, the timing control means is constituted by using the swing link 43 which is one component of the transmission means.
The timing control means can also be configured by using the elements 8 and 19 and setting the lever ratio appropriately. In the illustrated example, two door lock devices 1 are provided.
Although 8 and 19 are provided, even when three or more door lock devices are provided, each of the three or more door lock devices is sequentially unlocked by operation of one operating member so that the locks are sequentially performed at a later time. The lock release timing of the door lock device can be controlled.

FIG. 9 shows an example of the swing link 43 when three door lock devices are provided.
Has a third arm 51 in addition to the first and second arms 45 and 47, and a transmission element 52 connected to a third door lock device (not shown) is locked at the tip of the third arm 51. The distances R1, R2, and R3 from the center of rotation of the moving link 43 to the distal ends of the arms 45, 47, and 51 satisfy R3>R1> R2. Therefore, in this case, the lock of the third door lock device is first released, then the lock of the first door lock device 18 is released, and then the lock of the second door lock device 19 is released. In this way, the operating force can be reduced.

As can be seen from FIG. 8, when the locks of the door lock devices 18 and 19 are sequentially released,
The operating forces P ₁ and P ₂ required for unlocking the lock are sequentially increased. With this configuration, the operability can be enhanced without giving the operator a sense of discomfort. When the operation button 38 is depressed, if a maximum operation force is required first and then a smaller operation force is required, the operator feels strange and the operability is reduced.
This is because the operator usually recognizes that when the operation button 38 is pressed, the operation force gradually increases. The same applies to the case where three or more door lock devices are provided. When the unlocking of each door lock device is performed with a time lag, the operation force required for the unlock operation is sequentially increased to thereby improve the operation. Can be enhanced.

As described above, in the vehicle of this embodiment, when the unlocking of the plurality of door lock devices is sequentially performed, the operating force required for unlocking the doors is sequentially increased so that the operating force required for unlocking the door locking devices increases. Operating force control means for regulating the force is provided. Such control means adjusts, for example, a spring constant of a spring constituting each door lock device and a lever ratio of each element including an element of the transmission means. And can be appropriately configured.

It is needless to say that each of the above-described configurations can be adopted for the above-described inside handle. That is, when the inside handle, which is one operation member, is operated, the timing control that regulates the unlock timing of the door lock devices so that the unlocking of the plurality of door lock devices 18 and 19 is sequentially performed with a time interval. The means is provided. This control means can also be realized by, for example, configuring a transmission element interposed between the inside handle and each of the door lock devices 18 and 19 in the same manner as the swing link 43 shown in FIG. In addition, a plurality of door lock devices 18 and 19 are operated by operating the inside handle.
When unlocking is sequentially performed, an operating force control unit that regulates the operating force may be provided so that the operating force required for unlocking sequentially increases. The configuration can be made in exactly the same manner as described above.

By the way, as shown in FIG. 1, when the door 3 is in the closed position, the door 3 is connected to the first and second door lock devices 18 and 19 and the first and second strikers 2.
2 and 23, the door 3 is supported on the vehicle body 2 mainly at only two points. As shown in FIG. It is easy to fluctuate around the line L connecting the lines 18 and 19, whereby the sealing property in the vehicle interior is reduced, or the door may vibrate very slightly when the automobile is running, and wind noise may be generated.

When the door 3 occupies the closed position, the vicinity of the peripheral portion thereof comes into pressure contact with the weather strips 24 and 25 mounted along the door opening 10 of the vehicle body 2 as described above, and the sealing property of the vehicle interior I is improved. In this case, it is assumed that the door 3 occupying the closed position is supported by the vehicle body 2 mainly at only two places of the first and second door lock devices 18 and 19. Since the window frame 7 on the upper side of the door 3 is lower in rigidity than the door main body 6 therebelow, the window frame 7 is pushed out toward the outside O of the vehicle due to the elasticity of the weather strips 24 and 25. For this reason, the pressure contact force between the window frame portion 7 and the weather strips 24 and 25 is weakened, the sealing function at this portion is reduced, and there is a possibility that rainwater or wind may enter the vehicle interior I through this portion. Further, when the vehicle is running, the door 3 vibrates around the line L connecting the two door lock devices 18 and 19 to generate abnormal noise, or the window frame 7 is sucked out to the outside O of the vehicle, whereby Wind noise may be generated. The vehicle of this example is configured so that such disadvantages can be eliminated, and this point will be clarified below for reference.

In the vehicle of this embodiment, a door that holds the door portion below the line L connecting the first and second door lock devices 18 and 19 to the vehicle body 2 with the door 3 in the closed position. A holding means is provided, and in the illustrated example, the door holding means is constituted by a stopper 30 as shown in FIG. As shown in FIG. 10, the stopper 30 is formed in a cylindrical shape made of an elastic material such as rubber, and has a spiral thread groove 31 formed on an outer peripheral surface thereof. With the door 3 closed as shown in FIG. 5, a line L connecting the first and second door lock devices 18 and 19 shown in FIG.
A stopper mounting hole 32 is formed in the vehicle body portion (the floor panel 28 in this example) facing the door portion 3a below the lower end, and the stopper 30 is screwed into the mounting hole 32 and fixed.

When the door 3 is in the closed position, the stopper 30 attached to the vehicle body 2 is pressed against the above-mentioned door portion 3a and presses the door portion 3a in a direction to push the door portion 3a to the outside of the vehicle compartment. As a result, as shown in FIG. 4, the window frame 7 of the door 3 is attached to the weather strips 24, 25 attached to the vehicle body 2.
Of the weather strips 24, 25
Pressure with appropriate pressure.

As described above, when the door 3 is in the closed position, the line L connecting the first and second door lock devices 18 and 19 is formed.
The lower door portion 3a is moved by the stopper 30
The door 3 can be held on the vehicle body 2 and the position of the door 3 can be regulated. Thereby, it is possible to prevent the sealing function between the window frame 7 and the weather strips 24 and 25 from being hindered. In addition, the door 3 vibrates around the line L when the automobile is running, It is possible to prevent a problem that the airbag 7 is sucked out of the vehicle compartment. The stopper 30 has a very simple structure as compared with the door lock device, and its cost and weight can be reduced.

The stopper 30 is provided with a screw groove 3 on its outer periphery.
1 is screwed into the vehicle body 2 and its stopper 3
By turning 0, the amount by which the stopper 30 projects in the width direction of the vehicle body can be adjusted. For this reason, door 3
The position of the door 3 in the closed position can be correctly regulated by adjusting the amount of protrusion of the stopper 30 according to the installation state of the door 3.

In the example shown in FIG. 5, the stopper 30 constituting the door holding means is connected to the first and second door lock devices 1.
A stopper 30 presses against the door portion 3a in a state where the door 3 is in the closed position, and the stopper 30 presses the door portion 3a to restrict the position of the door 3 when the door 3 is in the closed position. However, the stopper 30 may be provided on the side of the door 3 as shown in FIG. That is, the door holding means is constituted by the stopper 30 shown in FIG. 10, and the stopper 30 is more than the line L (FIG. 1) connecting the first and second door lock devices 18 and 19 as shown in FIG. 11. The stopper 30 is provided on the lower door portion 3a and when the door 3 is in the closed position, the stopper 30 is moved to the door portion 3a.
The position of the door 3 is regulated by being pressed against the body portion facing the vehicle. Also in this case, by rotating the stopper 30, the amount by which the stopper 30 projects from the door portion in the width direction of the vehicle body 3 can be adjusted, and thereby the door 3 can be properly held at an appropriate position. .

Further, as shown in FIGS. 1, 6, and 12, a third striker 3

In this example, it is fixed to the front pillar 27. As shown in FIG. 12, a base member 35 is fixed to the inner panel 4 of the door 3, and the base member 35
The latch 34 described above is rotatably supported via 6. As can be seen from FIG. 1, the latch 34 includes first and second latches.
A door member below a line L connecting the door lock devices 18 and 19 is rotatably supported via a base member 35. When each end of a tension spring 37 is locked to the latch 34 and the base member 35, the latch 37 is urged to rotate clockwise in FIG. 12 by the spring 37, and the door 3 is opened. The latch 34 occupies the position indicated by the chain line in FIG. When the door 3 is closed, the pressing portion 34a of the latch 34 hits the third striker 33 and is pressed. When the door 3 reaches the closed position, the latch 34 rotates to the position shown by the solid line in FIG. 12 against the pulling action of the spring 37, and at this time, the latch 34 engages with the third striker 33. Also in this case, a cutout (not shown) is formed in the inner panel 4 of the door 3 so that the striker 33 can engage with the latch 34.
Relatively enter the notch and engage the latch 34. Similarly, a notch 35 a is formed in the base member 35.

As described above, when the door 3 occupies the closed position, the latch 34 engages with the third striker 33 to regulate the position of the door 3. The latch 34 is located below the line L connecting the first and second door lock devices 18 and 19, and the third striker 33 fixed to the vehicle body 2 at that position.

The door portion below line L connecting line 9 is held against vehicle body 2, and the door portion is pushed out of the vehicle compartment. This allows
The weather strip 2 attached to the vehicle body 2 has a window frame 7
4 and 25, and is pressed against the weather strips 24 and 25 with an appropriate pressure. In addition, it is possible to prevent the door 3 from vibrating around the line L and the window frame 7 from being sucked out of the vehicle compartment when the automobile is running.

When the door 3 is opened, the latch 34 is moved to the third striker 33 in accordance with the movement of the door 3.
And the latch 34 is rotated by the action of the spring 37 to the position shown by the chain line in FIG. Thus, when the door 3 is opened, the latch 34 naturally becomes the third strasker 33.
It is out of the way. For this reason, there is no need to provide an unlocking device for releasing the engagement between the latch 34 and the striker 33, and the configuration can be simplified, and an increase in cost and weight of the automobile can be suppressed. Latch 34
The latch itself is the same as the latches of the first and second lock devices 18 and 19, but in the configuration shown in FIG. 12, there is no means for releasing the engagement between the latch 34 and the third striker 33. As a result, the structure is simpler than that of the door lock device, and the weight is reduced.

In the illustrated vehicle, the stopper 30
Although the door holding means including the third striker 33 and the latch 34 are provided together, only one of the door holding means may be provided.

The present invention is widely applicable to various types of automobiles other than trucks.
