Problems solved by technology

[0008] As described above, if the direction of inertia acting on various movable parts is reversed from the outward direction to the inward direction, the invention described in Patent Document 1 has the following problem: when an impact is applied from the side, although the inertial operating lever moves from the first position Moves to the second position, but immediately returns to the first position without reliably constraining the open linkage
[0009] In addition, in the invention described in Patent Document 2, since the force applied to the inertial operating lever from the locked position toward the unlocked position is restricted by engaging the spring member with the restricting portion, when the direction of inertia acting on the inertial operating lever is reversed, There is also a risk of the spring member coming out of the restraint, moving the inertia lever towards the unlocked position

Embodiment Construction

[0026] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

[0027] Such as figure 1 As shown, the automobile door lock device 1 is installed in the door D, and the door D is freely opened and closed supported on the side of the vehicle body, as shown in FIG. figure 2 , 3 As shown, the automobile door lock device 1 includes: a base structure 2, which is fixed in the door D; an engaging mechanism 3, assembled on the base structure 2, which can lock the door D by engaging with the locking pin S fixed on the vehicle body. Keep in the closed state; and various movable parts described later are assembled on the base structure 2 .

[0028] Such as figure 1 As shown, an outside handle (door handle) OH is provided on the outside of the door D, and the outside handle OH is opened when the door D is opened from the outside of the vehicle. In addition, an inside handle (door handle) is provided on the inside of the door D. ) IH and ...

Abstract

The present invention provides an automobile door lock device capable of reliably maintaining a closed state of a door even when the direction of inertia acting on an inertial lever is reversed upon receiving an impact. When the opening link (17) is in the unlocked position, and the inertial operating lever (15) overcomes the force of the spring (26) to move from the standby position to the blocking position due to the inertial force exceeding the set value, the inertial operating lever ( 15) Abut against the opening link (17), so that the opening link (17) moves from the unlocked position to the locked position, and prevent the opening link (17) from moving from the locked position to the unlocked position, and the inertial operating lever (15 ) is prevented from moving from the blocking position to the standby position by engaging with the opening link (17).

Description

technical field [0001] The present invention relates to an automobile door lock device, and particularly relates to an automobile door lock device capable of maintaining a closed state of a door even when a side impact is received. Background technique [0002] Conventionally, for example, Patent Documents 1 and 2 describe an invention capable of maintaining the closed state of the door when the door receives an impact from the side. [0003] According to the invention described in Patent Document 1, the inertial operating lever is pivotally supported on the opening link that rotates in conjunction with the operation of the outside handle provided on the outside of the door, and an impact exceeding the set value acts due to an impact from the side. The inertial lever prevents accidental opening of the door by swinging from a first position avoiding abutment against the housing to a second position abutting the housing and constraining the opening link in the event of an iner...
