Description

[Detailed Description of the Invention] The present invention relates to an improvement of a locking device provided between an upper rail and a lower rail that enable the seat to move back and forth.

As shown in Figures 1 to 3, the locking device located at the bottom of the vehicle seat has the function of allowing the seat to be moved to a desired position and fixed at that position at all times. In many cases, a lock plate 2 is pivotally attached to the upper surface of the lower rail so as to be rotatable in the horizontal direction, and a claw 4 is pushed into a position regulating hole in the side surface of the lower rail 3 by a spring 10. Such a locking device 5 is provided on either one of the rails mounted parallel to the bottom of the seat, and is connected by a pull wire 6 to a locking device provided with a manual handle provided on the other rail. When the handle provided on one side is pulled, the device on that side and the lock device provided on the other side are simultaneously released.

Because of the above structure, the pull wire 6 must be locked to the lock plate 2. Therefore, conventionally, a hole for inserting a pull wire was provided at a point P located at a distance from the rotation axis 7 of the lock plate 2, and the pull wire was manually inserted and locked during assembly. This work was difficult and inefficient and had to be resolved. Further, referring to FIG. 4, in order to obtain the maximum movement of the claw 4 of the lock plate by the amount of movement of the pull wire, it is desirable that the attachment position P of the pull wire be within the area shown in the figure. . However, as mentioned above, it is difficult to attach the pull wire to this area.

The present invention solves the above-mentioned difficulties and is characterized by the fact that the pull wire is attached to the lock plate via a link plate rotatably mounted. Specifically, it is clear from the exemplary diagrams of FIGS. 2 and 3. Note that FIG. 1 is a front view of the main parts of the automobile seat, FIG. 2 is a front view of the locking device, and FIG. 3 is a plan view of the same. One end of a link plate 8 is pivoted to a point P that is a predetermined distance away from a rotation shaft 7 of a lock plate 2 that is pivoted to an upper rail 1. A wire passage hole 9 is provided at the other end of the link plate 8, and the pull wire 6 can be simply inserted into this hole and locked.

Generally, the space between the bottom surface of the seat and the top surface of the slide rail is narrow, making it difficult to attach the pull wire, but this invention solves this problem and greatly contributes to improving work efficiency.
