DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide door stopper provided on a vehicle body side.

[0002]

2. Description of the Related Art Conventionally, a slide door that slides in the front-rear direction of a vehicle body is provided on the side of the vehicle body of a one-box car or the like. As shown in FIG. It is supported by the held roller bracket 82.

A rear end of the sill outer 85 to which the lower rail 81 is fixed is provided with an extending portion 86 extending to the side of the vehicle body.
And a flange 8 extending from the extension 86 to the rear of the vehicle body R.
The flange 87 is fixed to the wheel house outer 89 via a rear fender 88. The sill outer 85 is provided with a rubber bracket 91 having a bumper rubber 90 with which the roller bracket 82 abuts and extending in the vehicle front-rear direction.
6 and a stopper for the sliding door is formed.

[0004]

However, since the lower rail 81 is provided with a rubber bracket 91 extending in the longitudinal direction of the vehicle body at the rear R thereof,
There is a problem that the overall length of the lower rail 81 is shortened. As a result, the amount of movement of the roller bracket 82 that slides in the lower rail 81 decreases, so that the opening stroke of the slide door supported by the roller bracket 82 decreases.

The present invention has been made in view of such a conventional problem, and an object of the present invention is to provide a slide door stopper structure which can increase the opening stroke of the slide door. .

[0006]

According to the present invention, there is provided a slide door having a contact surface disposed on a rear end of a sill outer provided with a lower rail of a slide door and extending from the lower rail. A stopper member having a stopper is provided, and a reinforce extending along the stopper member and the sill outer is provided along with the stopper member, and an end of the reinforce is fixed to the lower rail together with the sill outer. A bumper rubber that moves in the lower rail and supports the slide door is provided on a roller bracket that contacts the contact surface of the stopper member.

That is, the roller bracket which moves in the lower rail provided on the sill outer is provided until the bumper rubber provided on the roller bracket comes into contact with a contact surface of a stopper member provided on the rear end of the sill outer. Be moved. The stopper member is provided alongside the stopper member, and is reinforced by a reinforce fixed to the lower rail together with the sill outer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a view showing a side portion of a vehicle body 1 provided with a stopper portion structure of a slide door according to the present embodiment, and a rear seat 3 is provided between a center pillar 2 and a rear pillar 3 of the vehicle body 1. An entrance 4 is provided.
A lower rail 6 of a slide door (not shown) that opens and closes the entrance 4 is provided in a side sill 5 provided below the entrance 4 to extend in the front-rear direction of the vehicle body.

That is, as shown in FIG. 2, the lower rail 6 is fixed to a sill outer 11 forming the side sill 5, and a rear end of the sill outer 11 has a stopper member thicker than the sill outer 11. An extension sill outer 12 is provided. As shown in FIGS. 2 and 3, the extension sill outer 12 extends from the sill outer 11 to the rear side of the vehicle body, and is fixed to a rear end portion of the sill outer 11. From 15 is bent in the O direction outside the cabin,
A contact surface 16 disposed on an extension of the lower rail 6;
It comprises a bent surface 18 bent from the corresponding contact surface 16 to the rear R of the vehicle body via an inclined surface 17, and the bent surface 18 is provided via a rear fender 19 to a wheel house outer 21 forming a tire opening 20. It is fixed.

As shown in FIG. 3, first and second upper jog surfaces 31 and 32 corresponding to the sill outer 11 are formed on the upper portion of the fixing surface 15 of the extension sill outer 12 by bending. The first and second
The upper and lower jogging surfaces 31 and 32 are formed on the third and fourth upper jogging surfaces 3 that are bent above the contact surface 16.
3 and 34, respectively. A lower joggle surface 35 is formed below the fixing surface 15 and is bent in the direction of the vehicle compartment I.
5 is connected to the lower edge of the contact surface 16. The lower joggle surface 35 is formed with a downwardly depending surface 36 which is suspended downward, and the hanging surface 36 is provided continuously with the lower edge of the bent surface 18.

The extension sill outer 1
2, a first extending surface 41 extending along the contact surface 16 of the extension sill outer 12 and a fixing surface 15 of the sill outer 11 extend as shown in FIG. A reinforcement 43 including a second extending surface 42 is provided, and the second extending surface 42 is set to have a length overlapping with a rear end of the lower rail 6. In this reinforcement 43, the first extending surface 41 is fixed to the contact surface 16 of the extension sill outer 12, and the end of the second extending surface 42 is connected to the sill outer 11 together with the sill outer 11. It is fixed to the lower rail 6.

On the other hand, in the lower rail 6, while supporting the slide door, a plurality of rollers 51,.
The roller bracket 52 provided with ・ is slidably held. At the rear end of the roller bracket 52,
A bumper rubber 53 projecting from the contact surface 16 of the extension sill outer 12 disposed on the extension of the lower rail 6 is provided in a protruding manner.

In the embodiment having the above-described configuration, the roller bracket 52 that moves in the lower rail 6 provided on the sill outer 11 is
The bumper rubber 53 provided on the sill outer 1
1 extension sill outer 1 provided at the rear end
2, a rubber bracket extending in the vehicle front-rear direction is provided on the rear side R of the vehicle body from the lower rail 6.
The length of the lower rail 6 can be set longer than in the related art in which it was not possible to extend to the rear end of the sill outer 11 provided with the lower rail 6. As a result, the amount of movement of the roller bracket 52 that slides in the lower rail 6 can be increased, so that the opening stroke of the slide door supported by the roller bracket 52 can be increased. The frontage at the entrance 4 of the vehicle can be widened.

The extension sill outer 1
2 is attached to the extension sill outer 12 and the lower rail 6 together with the sill outer 11.
Since the reinforcement 43 can be reinforced by the reinforcement 43, the extension sill outer 12 can be prevented from being deformed when the bumper rubber 53 projecting from the roller bracket 52 abuts.
Further, since the reinforce 43 is fixed to the sill outer 11 of the side sill 5 constituting the vehicle body, the skeleton of the vehicle body can be strengthened.

[0015]

As described above, in the present invention,
Moving the roller bracket moved in the lower rail provided on the sill outer until the bumper rubber provided on the roller bracket comes into contact with a contact surface of a stopper member provided on the rear end of the sill outer; Therefore, a rubber bracket extending in the vehicle front-rear direction behind the lower rail is provided, and the lower rail is
The overall length of the lower rail can be made longer than in the conventional case where the lower rail cannot be extended to the rear end of the sill outer provided with the lower rail. Thus, the amount of movement of the roller bracket that slides in the lower rail can be increased, so that the opening stroke of the slide door supported by the roller bracket can be increased.

Further, the stopper member is provided in parallel with the stopper member and can be reinforced by a reinforce fixed to the lower rail together with the sill outer, so that the bumper rubber provided on the roller bracket can be used. The deformation of the stopper member at the time of contact can be prevented. Further, since the reinforce is fixed to the sill outer constituting the vehicle body, the skeleton of the vehicle body can be strengthened.
