Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a door lock device for vehicles and the like.

Prior Art Generally, a door lock device (31) for a vehicle, etc. is a mechanism that opens and opens a door by engaging and disengaging a latch and a striker. Functionality is ensured.

This J, about the technology around the general door, automatic i1
It is described on the specified page of Volume 13 of N Engineering Money Writing Mountain if + J Domitsu Tj).

1~Around seal function 4J, door fully closed (closed 1) 7! For example, a grounding helix installed on the door side or around the door (4) on the body side is elastically deformed between the vehicle body side and the door side to ensure watertightness. Therefore, in order to obtain good sealing performance by using sea urchin + f + strip, it is sufficient to set the riser strip to a sheet with reaction force characteristics that can obtain a high sealing reaction force, but it is not necessary to If a seal with a high reaction force is used, the effect of the reaction force will be heavier when the door is closed than when the door is ajar.When the door is opened suddenly, the reaction force will push the door back and cause C engagement (striker). There is also the risk of a defect in the engagement between the latch and the latch, which poses a problem in terms of closing performance.

Purpose of the invention Therefore, this invention IJ, +311 ji 1' of the door! [I am trying to improve the stable I,
(There is.)

In order to achieve the above object of the invention, in this invention, the engagement position of the latch with the king play 1 is changed to a half-door shape! To the outside, pull the door in the full latch position further towards the Φ body side and engage it with the label closed. In the closed ITl' state, set the drive mechanism to avoid forced LC operation.1.1.
- Hatrahel 113 door 1 person (1) - The seal reaction force of the strip is increased to make the seal M direction -1 bow -2.

Embodiment Hereinafter, one embodiment of the present invention will be described in detail in Section 4 with reference to the drawings in FIGS. 1 to 10.

In Figure 1, 1 indicates the door of the white motor vehicle 5 that can be opened and closed using the hinge 33 as a fulcrum. A melting soil 1f-strip 9 is installed.

The door lock mechanism 7 (hereinafter referred to as door lock in 11j)
is fixed to the inner relays 1 to 1 of the door 1, is pivoted 23 on the base brake 21, and has a latch 11, and a striker 15 that can engage with the latch 11 and is installed on the inner side 13; The latch 11 has an X-engaging plate 17 that engages with the wrap 11 when the latch 15 is engaged. The latch 11 is inserted into the notch 625 cut out in the inner brake 1 of the open openings 19atJ1.1-71 of the meshing surface 19 when the latch 11 is in the closed state a3 and the striker 15 moves forward and backward.

On the other hand, it is pivoted 27 on the 11-tuned λ-ring brakes 1 to 171U, 7\-Sugrei-i-21, and l=, and is held in the position shown in Fig. 6 by a spring (not shown) when the door is closed.
There is C. At 0flH ahead of the locking brake 1-17, I is the 1st part of the 1st gear 11. A pawl ri+ (35 is formed) that engages with each second engaging part 11 29, 31° 33, respectively.
When the door opening/closing operation handle 3.6.38 is operated, the claw portion 35 rotates in the direction δj at 1 o'clock in FIG.
