Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operating lever used for a seat track, and more particularly to an operating lever for disengaging a slide rail stopper of a movable rail from a tooth row of a fixed rail.

[0002]

[Background Art] In a seat track used for automatic seats, an operation lever that hangs a slide rail stopper of left and right movable rails on a tooth row of left and right fixed rails is bent into a substantially U shape, and both ends are bent. The left and right slide rail stopper holders are attached so that they can be prevented from slipping off, and are joined, so when the left and right fixed and movable rails are mounted on the floor in the front, rear, left, and right directions, the operation lever twists and twists. It is transmitted to the slide rail stopper, and the slide rail
The stopper may impair the lock operation load performance.

[0003]

An object of the present invention is to provide an operating lever used for a seat track, which absorbs a twist due to misalignment of left and right fixed and movable rails and can secure a lock operation load performance to a slide rail stopper. Is provided.

[0004]

Means corresponding to the object and the operation thereof
A main lever that has a handle arm integrally at the tip and fixedly connects the root to one holder of the left and right slide rail stoppers, and a connecting arm at the tip that connects the handle arm to the handle It is connected to the arm so that it can move back and forth and left and right within a predetermined range, and the left and right slides
Includes a cooperative lever that fixedly connects the root to the other holder of the rail stopper, and absorbs twist due to left and right fixed and movable rail misalignment at the connection point between the handle arm and the connection arm I am about to do it.

DESCRIPTION OF SPECIFIC EXAMPLES Hereinafter, the operating lever used in the seat truck of the present invention will be described based on the specified and illustrated specific examples. FIGS. 1 and 2 show a seat track of a passenger car seat. 20 shows a specific example 10 of the operating lever used in the seat track of the present invention as applied to 20. In this operating lever 10, the main lever 11
However, the handle arm 13 is integrally formed at the tip, and is inserted and coupled to the holder 29 of one of the left and right slide rail stoppers 26, 27 so that the root can be prevented from coming off.
Further, the cooperating lever 12 has a connecting arm 14 at its tip, and connects the connecting arm 14 to the handle arm 13 so as to be movable back and forth and left and right within a predetermined range, and the left and right slide rails. The other 2 of the stoppers 26 and 27
The base is inserted into the holder 28 of No. 6 so as to prevent the base from coming off, and is coupled.

The main lever 11 has its handle arm 13 bent at its tip, and in particular, the handle arm 13 is bent into a substantially U shape, opened in the left-right direction, and extends in the front-rear direction. Slots 19, 1
Brackets 17, 18 having 9 are provided on the arm root 15 and the arm tip 16 respectively by welding, and the connecting arm 14 is penetrated through the slots 19, 19 of the brackets 17, 18 to attach the cooperating lever 12 thereof. It is connected to the main lever 11. Of course, that slot 19,
Reference numeral 19 eliminates vertical rattling by making the short diameter a substantially equal to the outer diameter of the connecting arm 14, and allows the front and rear mounting deviation to be absorbed by the long diameter b, and the left and right mounting deviation can be absorbed by penetrating. To Further, the handle arm 13 is bent into a substantially U-shape as shown in the drawing so that the lateral shift amount of the main lever 11 and the cooperating lever 12 can be absorbed.

The cooperating lever 12 has its main lever 12
Similarly, the connecting arm 14 is bent at the tip.

In the seat track 20 utilizing the operating lever 10, 21 and 22 are left and right fixed rails, 23 and 24 are left and right movable rails, and 2
5 is a row of teeth.

Therefore, in the operating lever 10, even if the left and right fixed rails 21 and 22 are attached to the floor of a passenger car in the front-rear and left-right directions, the handle arm 13 and the connecting arm 14 are connected to each other. The mounting deviation is absorbed, and the lever twist due to the mounting deviation is avoided, so that the slide rail stoppers 26, 27 have the lock operation load performance.

As will be apparent from the specific embodiments of the present invention described above with reference to the drawings, those of ordinary skill in the art to which the present invention pertains have the subject matter of the present invention. Is the nature of the invention (na
), and are readily embodied in other aspects that are objectively perceived as inherent in them. Of course, the content of the present invention corresponds to the subject of the invention (be commensu).
rate with) and essential for the invention.

[0011]

As will be understood from the above, the operating lever used in the seat track of the present invention has a handle arm integrally at its tip and has one holder for the left and right slide rail stoppers. A main lever that fixedly connects the root to the base, and a connecting arm at the tip that connects the connecting arm to the handle arm so that it can move back and forth and left and right, and the left and right slide rails.・
Since the other lever of the stopper includes the cooperating lever that fixedly connects the root to the other holder, in the operation lever used in the seat track of the present invention, the seat track has the left and right fixed and movable rails on the floor in the front, rear, left and right directions. The misalignment due to misalignment is absorbed at the connection point between the handle arm and its connecting arm, and the lever twist due to the misalignment is avoided, and the slide rail stopper is locked to the load capacity. Is ensured and, as a result, is very useful and practical for seat trucks.
