From the state in which the function of the second stopper 5 is off, the function of the second stopper 5 is turned on by strengthening the fastening of the bolt 5 and sending the bolt 5 to the inside of the fixed rail 2. As described above, the second stopper 5 is configured to be capable of switching on and off the stopper function.

<Bracket>
The bracket 6 is a member fixed to the fixed rail 2. As shown in FIGS. 6 and 7, the bracket 6 includes a first plate-like portion 6A, a second plate-like portion 6B, a nut 6C, and two claw portions 6D. The bracket 6 is made of metal, for example.

  The first plate-like portion 6A is a plate-like portion whose plate surface is perpendicular to the sheet width direction (that is, extends in the up-down direction and the slide direction). The first plate-like portion 6A is disposed outside the side wall 2E of the fixed rail 2 in the seat width direction.

  The second plate-like portion 6B is a plate-like portion whose plate surface is perpendicular to the vertical direction (that is, extends in the sheet width direction and the slide direction). The second plate-like portion 6B is connected to the lower end of the first plate-like portion 6A and is disposed below the bottom wall 2C of the fixed rail 2.

As shown in FIG. 7, the second plate-like portion 6 </ b> B is fixed to the bottom wall 2 </ b> C of the fixed rail 2 with a plurality of bolts 7.
The nut 6 </ b> C is a part for fastening the bolt 5. The nut 6C is fixed to the first plate-like portion 6A, for example, by welding.

  The two claw portions 6D are portions that protrude upward from the second plate-like portion 6B. Each of the two claw portions 6D penetrates the bottom wall 2C of the fixed rail 2 in the vertical direction. Specifically, as shown in FIG. 6, the two claw portions 6 </ b> D are inserted into the through holes that constitute the pressure receiving portion 2 </ b> F of the fixed rail 2, and protrude into the fixed rail 2.

  When the bracket 6 is pressed to the first end 2A side of the fixed rail 2 via the bolt 5 fastened to the nut 6C, the two claw portions 6D are configured to move the fixed rail 2 toward the first end 2A. The pressing part to press is comprised. In other words, when the movable rail 3 collides with the bolt 5, the claws 6 </ b> D collide with the pressure receiving portions 2 </ b> F, so that the force received by the bolt 5 from the movable rail 3 is applied to the bracket 6 and the fixed rail 2. Dispersed across multiple surfaces.

  Further, the two claw portions 6D are arranged closer to the first end portion 2A of the fixed rail 2 than the nut 6C. The surface on the second end 2B side of the fixed rail 2 in the two claw portions 6D constitutes the first stopper 4 as described above.

  That is, in the state where the second stopper 5 does not function (that is, the bolt 5 is not inserted into the fixed rail 2), the protrusion 3A provided on the bottom surface of the movable rail 3 is a claw portion as shown in FIG. The sliding of the movable rail 3 toward the first end 2 </ b> A side of the fixed rail 2 is restricted by contacting the first stopper 4 formed by 6 </ b> D. FIG. 4 shows a state in which the movement of the movable rail 3 is restricted by the first stopper 4 as described above.

  The bolt 5 and the bracket 6 may be provided on either side of the two side walls 2D and 2E of the fixed rail 2. However, from the viewpoint of reducing the visibility of these members during use of the vehicle seat, these members are arranged on the side wall located on the inner side in the seat width direction of the vehicle seat, out of the two side walls of the fixed rail 2. It is preferable.

  When a plurality of slide structures are attached to one vehicle seat, the bolts 5 and the brackets 6 (that is, the first stopper 4 and the second stopper 5) do not need to be provided on all the slide structures. In this case, it is preferable to provide the first stopper 4 and the second stopper 5 at least on the slide structure closest to the center of gravity of the vehicle seat.

  The slide structure 1 includes a third stopper (not shown) configured to restrict the slide of the movable rail 3 toward the second end 2B side of the fixed rail 2 by contacting the movable rail 3. Yes. FIG. 3 shows a state where the movement of the movable rail 3 is restricted by the third stopper.

The method for assembling the vehicle seat according to the present embodiment is a method for assembling a vehicle seat including the seat cushion S, the fixed rail 2, the movable rail 3, and the first stopper 4 to the floor of the vehicle.

  Hereinafter, the assembling method will be described using a vehicle seat including the leg 8 fixed to the lower surface of the fixed rail 2, but the vehicle seat does not necessarily need to include the leg 8. That is, the fixed rail 2 may be directly fixed to the floor.

  As shown in FIG. 9, the vehicle seat assembly method of the present embodiment includes a first slide step S10, a first fastening step S20, a second slide step S30, a second fastening step S40, and a third slide. Step S50 and stopper adjustment step S60 are provided.

<First slide process>
In this step, as shown in FIG. 10A, the movable rail 3 is slid to the second end 2B side of the fixed rail 2 to be in the first sliding state. Specifically, the movable rail 3 is slid to a position where it comes into contact with a third stopper (not shown) of the fixed rail 2 and stops.

  It should be noted that the bolt 5 is not attached to the fixed rail 2 at this time or is disposed at a position where it does not contact the movable rail 3. That is, at this time, the function of the second stopper 5 is turned off.

<First fastening process>
In this step, the fixed rail 2 is fastened to the vehicle floor via the legs 8 in the first sliding state. Specifically, the tool T is brought into the space on the front side of the seat provided by the slide of the movable rail 3, and the portion of the leg 8 on the first end 2A side (that is, the front side of the seat) of the fixed rail 2 is placed on the floor with the bolt 9A. Conclude.

<Second slide process>
In this step, as shown in FIG. 10B, the movable rail 3 is slid to the first end 2A side of the fixed rail 2 to be in the second sliding state. Specifically, the movable rail 3 is slid to a position where it comes into contact with the first stopper 4 of the fixed rail 2 and stops. This second slide state is an overstroke state in which the vehicle has slid to the front side of the seat with respect to the slide region in the use state of the vehicle seat.

<Second fastening process>
In this step, the fixed rail 2 is fastened to the vehicle floor via the legs 8 in the second sliding state. Specifically, the tool T is brought into the space on the rear side of the seat provided by the slide of the movable rail 3, and the second end 2B side (that is, the rear side of the seat) of the fixed rail 2 in the leg 8 is secured with a bolt 9B. Fasten to the floor.

<Third slide process>
In this step, as shown in FIG. 10C, the movable rail 3 is slid to the second end 2B side of the fixed rail 2 after the second fastening step S40. Specifically, the movable rail 3 is slid to the second end 2B side from the attachment position of the second stopper 5 (that is, the insertion position of the bolt 5).

<Stopper adjustment process>
In this step, after the third sliding step S50, the second stopper 5 is attached at a position farther from the first end 2A of the fixed rail 2 than the first stopper 4, and the function of the second stopper 5 is turned on. Specifically, the bolt 5 is inserted into the fixed rail 2 to a position where it abuts on the movable rail 3. By adjusting the second stopper 5, the slide area is narrowed to a range when the vehicle seat is used.

[1-3. effect]
According to the embodiment detailed above, the following effects can be obtained.
(1a) When the vehicle seat is fixed, only the first stopper 4 of the first stopper 4 and the second stopper 5 functions so that the sliding area of the movable rail 3 is increased and the working efficiency is increased. It is done. On the other hand, after the fixing work, the sliding area of the movable rail 3 is reduced by causing the second stopper 5 provided inside the fixed rail 2 to function rather than the first stopper 4, so that the range in the usage state of the vehicle seat is reduced. The slide area can be easily adjusted. Therefore, the present disclosure can improve the assembly efficiency of the vehicle seat with a simple configuration.

  (1b) By using the bolt 5 extending in the direction perpendicular to the sliding direction of the movable rail 3 toward the inner side of the fixed rail 2 as the second stopper 5, positioning of the second stopper 5 in the sliding direction becomes easy. . Therefore, the positional accuracy of the second stopper 5 is improved. Further, the function of the second stopper 5 can be easily switched on and off by adjusting the fastening state of the bolt 5 using a tool used for fastening the vehicle seat.

  (1c) The nut 6 </ b> C can be easily attached to the fixed rail 2 by the bracket 6. That is, since it is not necessary to weld the nut 6C directly to the fixed rail 2, the shape accuracy of the fixed rail 2 is improved. Further, since the bracket 6 has the claw portion 6D, the impact when the movable rail 3 comes into contact with the second stopper 5 is dispersed in the sheet width direction, so that the displacement and deformation of the second stopper 5 are suppressed.

  (1d) Since the 1st stopper 4 is comprised by the nail | claw part 6D of the bracket 6, it is not necessary to provide the 1st stopper 4 and the press part which presses the fixed rail 2 in a sliding direction separately. Therefore, the number of parts can be reduced.

[2. Second Embodiment]
[2-1. Constitution]
FIG. 11 is a view showing a part of the fixed rail 2 and the second stopper 15 in the vehicle seat slide structure of the second embodiment.

In 2nd Embodiment, since the fixed rail 2 and the movable rail 3 are the same as that of the slide structure 1 of FIG. 1, description of these structures is abbreviate | omitted.
As shown in FIG. 11, the second stopper 15 in the present embodiment is configured as a cap attached to the first end 2 </ b> A of the fixed rail 2. The second stopper 15 is made of, for example, resin. The second stopper 15 extends in the direction from the first end 2A to the second end 2B of the fixed rail 2 (that is, from the front side of the seat toward the rear side).

  The second stopper 15 regulates the sliding of the movable rail 3 toward the first end 2 </ b> A side (that is, the front side of the seat) of the fixed rail 2 by the tip portion 15 </ b> A contacting the tip of the movable rail 3.

Further, the claw portion 6 </ b> D of the bracket 6 does not necessarily constitute the first stopper 4. Furthermore, the bracket 6 does not necessarily have the claw portion 6D.

  Therefore, for example, as shown in FIG. 12, the slide structure 1 may have a structure having only the first plate-like portion 6A and the nut 6C. In this case, the first stopper is constituted by a part of the fixed rail 2 or another member.

(3b) In the vehicle seat slide structure 1 of the above embodiment, the second stopper 5 may not be a bolt.
For example, as shown in FIG. 13, a cylindrical stopper pin 25 penetrating the side wall of the fixed rail 2 may be used as the second stopper. In FIG. 13, the stopper pin 25 has an enlarged diameter portion 25 </ b> A whose diameter is larger than that of other portions. Further, the stopper pin 25 passes through the bracket 26 </ b> A attached to the side wall of the fixed rail 2.

  A coil spring 26B is wound around a portion between the enlarged diameter portion 25A of the stopper pin 25 and the bracket 26A. The stopper pin 25 is pressed toward the inside of the fixed rail 2 by the elastic force of the coil spring 26B.

  In FIG. 13, the function of the second stopper can be turned off by moving the stopper pin 25 toward the outside of the fixed rail 2 while compressing the coil spring 26 </ b> B. At this time, the lock member is fixed to a portion protruding outward from the bracket 26A so that the stopper pin 25 does not move to the inside of the fixed rail 2 by the restoring force of the coil spring 26B. As the lock member, for example, a pin that penetrates the stopper pin 25 in the radial direction can be used. By removing the lock member, the function of the second stopper can be switched from OFF to ON.

  Furthermore, as shown in FIG. 14, a stopper bracket 35 penetrating the side wall of the fixed rail 2 may be used as the second stopper. In FIG. 14, the stopper bracket 35 is attached to the fixed rail 2 by the auxiliary bracket 36. The auxiliary bracket 36 is fixed to the fixed rail 2 by welding or the like, and is fastened to the stopper bracket 35 with bolts 37.

  In FIG. 14, the function of the second stopper is turned on by inserting the tip end portion of the stopper bracket 35 into the inside from the side wall of the fixed rail 2 and fastening the stopper bracket 35 to the auxiliary bracket 36.

  (3c) The vehicle seat slide structure 1 according to the above embodiment can be applied to a vehicle seat other than a passenger car, and a seat used for a vehicle such as a railway vehicle other than an automobile, a ship, and an aircraft.

  (3d) The functions of one component in the above embodiment may be distributed as a plurality of components, or the functions of a plurality of components may be integrated into one component.
