FIG. 6 is an exploded perspective view showing an example of the conventional example. In the drawing, reference numerals 101 and 102 denote slide rails, and a fixed rail a mounted on the vehicle body floor, and a movable rail b slidable with respect to the fixed rail a and mounted on the seat body 100 side. It is composed of
[0004]
The slide rails 101, 102 are mounted by fixing the leg brackets 104, 105, 106 fixed to the fixed side rail a to the mounting members 108, 109 fixed to the vehicle body floor 107 with bolts 110.
[0005]
In particular, the leg bracket 103 behind the fixed side rail a in the slide rail 101 inside (center side) of the vehicle body is fixed to the slope 112a of the vehicle body tunnel 112 with a bolt 110 to secure a foot space for the rear seat. ing.
[0006]
[Problems to be solved by the invention]
However, if the leg bracket 103 behind the fixed side rail a of the slide rail 101 is simply attached to the vehicle body tunnel slope 112a with the bolt 110, the seat setting is unstable because the seat attachment surface is inclined. However, there are problems such as difficulty in positioning, incorrect mounting, and in the worst case, distortion of the seat frame. there were.
[0007]
The present invention has been made in view of such circumstances, the seat setting is stable, it is possible to accurately fix the seat to the vehicle body without generating distortion or the like in the seat frame, also for workers An object of the present invention is to provide a structure for mounting a slide rail in a vehicle seat in which a seat setting operation can be stably performed and positioning can be easily performed.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the slide rail mounting structure of the vehicle seat according to the first aspect of the present invention is configured such that a movable rail mounted on the seat side is slidable with respect to a fixed rail mounted on a vehicle body floor. In the slide rail of the seat adjuster mechanism, a locking portion is formed on the slope of the vehicle body tunnel, and a leg bracket fixed to the rear side of the fixed side rail of the slide rail on the vehicle interior center side engages with the locking portion. A mating portion is formed, and the engaging portion is engaged with the locking portion by being brought into contact with the locking portion from above to be mounted .
[0009]
The invention according to claim 2 is the mounting structure for a slide rail in the vehicle seat according to claim 1 , wherein the locking portion is a pin with a collar, and the engaging portion is related to the pin with a collar. It is characterized by slits that match .
[0010]
According to a third aspect of the present invention, there is provided the mounting structure of the slide rail in the vehicle seat according to the first aspect , wherein the locking portion is a locking member formed of a wire or a plate. The portion is a hook portion that is hooked on the hooking member .
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a main part showing an embodiment of the present invention, FIG. 2 is a front view thereof, and FIG. 3 is a side view thereof. As in the conventional example shown in FIG. Although not shown, a slidable movable rail is mounted on the fixed side rail on the seat body, and the leg bracket fixed to the fixed side rail is fixed to the mounting member on the vehicle body floor by bolting. This part is omitted, and only the main parts of the present invention are shown in the drawings.
[0015]
In FIG. 1, a vehicle body tunnel 1 is formed substantially in the center of a vehicle body floor (between a left seat and a right seat) in a front-rear direction, and a slope 1a of the vehicle body tunnel 1 is provided with a collar as a locking portion. The attachment pin 2 is provided in a protruding manner.
[0016]
The slide rail 3 is composed of a fixed rail 3a and a movable rail 3b, and a seat body (not shown) is mounted on the movable rail 3b so that the front and rear positions can be adjusted. A slit 5 is formed in the leg bracket 4 fixed to the rear of the fixed side rail 3a as an engaging portion that engages with the collar pin 2.
The leg bracket 4 has a rising piece 4a and a hanging piece 4b, the slit 5 is formed in the hanging piece 4b, and an elongated hole 7 through which a bolt 6 is inserted is formed in the rising piece 4a.
[0017]
The elongated hole 7 of the rising piece 4a is for fixing the leg bracket 4 to the vehicle body tunnel slope 1a with a bolt 6, and the vehicle body tunnel slope 1a is provided with a bolt hole 8 therefor.
[0018]
Thus, the leg bracket 4 (that is, the seat) is set by engaging the slit 5 with the collar pin 2, inserting the bolt 6 into the elongated hole 7 and temporarily fixing the bolt 6 to the bolt hole 8, and positioning the leg bracket 4. Then, the bolts 6 can be attached by tightening the bolts. 2 and 3 show the mounted state.
[0019]
FIG. 4 is a perspective view of a main part showing another embodiment of the present invention. In this example, the locking portion is the pocket 12, the engaging portion is the insertion piece 15 to be inserted into the pocket 12, and the other portions are the same as those in the above embodiment, and the same components are denoted by the same reference numerals.
[0020]
That is, a pocket 12 is formed from a plate on the slope 1a of the vehicle body tunnel, and the tip of the hanging piece 4b of the leg bracket 4 is formed on an insertion piece 15 that is inserted into the pocket 12.
Therefore, also in this example, setting can be performed by inserting the insertion piece 15 into the pocket 12.
[0021]
FIG. 5 is a perspective view of a main part showing still another embodiment. In this example, the locking portion is a hooking member 22, the engaging portion is a hook portion 25 that hooks on the hooking member 22, and the other components are the same as those of the above-described embodiment. It is.
[0022]
That is, in this embodiment, a handle-shaped hooking member 22 is fixedly formed of a wire on the vehicle body tunnel slope 1a, and a hook portion 25 hooked to the hanging member 22 is formed on the hanging piece 4b of the leg bracket 4. It is. This hook member 22 may be formed of a plate material. Therefore, also in this example, setting can be performed by hooking the hook portion 25 on the hooking member 22.
[0023]
In the above-described embodiment, an example has been described in which the locking portion is formed on the slope 1a of the vehicle body tunnel, and the engaging portion is formed on the leg bracket 4 of the fixed side rail 3a. A support portion (not shown) may be formed only on the slope 1a, and the leg bracket may be simply supported by the support portion. This is because the seat setting can be stabilized by supporting (abutting) the lower end of the leg bracket on the supporting portion. The supporting portion is preferably a pin with a collar, a stepped bolt, or the like.
[0024]
【The invention's effect】
As described in detail above, the present invention relates to a slide rail of a seat adjuster mechanism that allows a movable rail mounted on a seat to slide with respect to a fixed rail mounted on a vehicle body floor. A leg bracket fixed to the rear side of the fixed side rail of the slide rail on the center side of the vehicle is supported by the support portion and attached, and a locking portion (a pin with a collar, a pocket, a hook, An engaging portion (slit, insertion piece, hook portion) that engages with the locking portion is formed on the leg bracket fixed to the rear side of the fixed side rail of the slide rail on the center side in the vehicle. The engaging portion is engaged with the engaging portion so as to be attached, so that not only the seat setting is stabilized, but also the front and rear - vertical-width direction of the positioning it is easy to correct mounting is possible, never causing a distortion or the like to the seat frame. As a result, there is no occurrence of a lock synchronization shift of the double-sided lock type.
[0025]
In addition, the seat setting operator can easily and stably perform the setting operation of the seat and can easily perform the positioning.
