Description

[Detailed Description of the Invention] This invention relates to a guide portion structure of a sliding door for a vehicle.

2. Description of the Related Art Conventionally, a vehicle such as a so-called one-box car has been provided with a sliding door that is slid along the side surface in the front-rear direction to open and close an opening on the side of the vehicle.

Such a sliding door for a vehicle usually has a guide rail and a guide mechanism at two locations on the front side of the door, one above the other, and one location on the rear side of the door, approximately at the center of the door. Generally, the guide rails installed above and below the door are located inside the door, and when the door is closed,
It is hidden from the outside to improve the confidentiality of the cabin and the exterior appearance. The substantial opening width secured when the door is opened is limited to the shortest of the three guide rails. Usually, this applies to the guide rail at the top of the door, so the substantial opening width of the door is limited to the front and back range of the upper side of the vehicle side opening.

By the way, the shape of the vehicle side opening (shape of the door)
This has a significant impact on the ease of getting on and off the vehicle. In particular, the lower half of the door needs to be wide open from front to back, considering the movement of the occupant's waist when getting on and off the vehicle. The upper half of the door may be narrower than the lower half, considering the posture of the occupant when getting on and off the vehicle (rear doors allow passengers to get on and off while leaning forward). Therefore, in the case of many passenger cars, since the upper part of the vehicle is trapezoidal, the shape shown in FIG. 4A is often adopted for the front door, and the shape shown in FIG. 4B is often adopted for the rear door.

However, even if the door shape is adopted in this way, when the door is opened, it must be ensured that the opening width is substantially the same as that of this door shape, especially in the lower half. Problems arise when actually getting on and off the vehicle. Therefore, whether the door has the shape of FIG. 4A or the door of FIG. 4B, there is a problem in that the ease of getting in and out of the vehicle may be impaired unless the doors are opened wide as shown by the broken lines.

In addition, in order to solve this problem, for example,
48-33125, if the guide rail is simply extended rearward (or forward) beyond the rear edge (or front edge) of the door opening, the door will not run along the outside of the vehicle body. Since the guide rail cannot be attached to the inside of the vehicle body due to the opening, the guide rail ends up extending to a portion of the outside of the vehicle body side where the door opening does not exist at all. As a result, a problem occurred in that the appearance quality deteriorated.

This idea was made in view of the above-mentioned conventional problems, and is a sliding door for a vehicle that improves the side appearance of the vehicle while preventing the front-to-back length of the upper part of the door from being restricted by the guide rail. The purpose of the present invention is to provide a guide section structure.

This invention includes a roof side rail with a closed cross section along the upper side of a vehicle side opening that is opened and closed by a sliding door, a roof drip channel formed along the edge of the roof panel in the vehicle body width direction, and A guide portion structure for a sliding door for a vehicle, comprising a guide rail provided along the rail, and a roller attached to the upper part of the sliding door via an arm and in rolling contact with the guide rail, wherein the roof side rail is provided with a guide rail. , forming a concave portion having a generally U-shaped vertical section that expands toward the inside in the vehicle width direction and toward the outside of the vehicle body, and extending the roof side rail forward or backward beyond the front side or rear side of the vehicle side opening. extending, the guide rail is provided in a U-shaped recess of the roof side rail, and the lower end of the roof drip channel is substantially covered by the guide rail in the recess;
In addition, the above object is achieved by hanging down to a position where there is a minimum vertical clearance in which the arm can slide without any trouble.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 to 3, this embodiment includes a guide rail 5 provided within a roof side rail 4 along the upper side of a side opening 3 of a vehicle 2 that is opened and closed by a sliding door 1; It is attached to the upper part of the sliding door 1 via the arm 6, and
A sliding door guide mechanism for a vehicle includes a roller 7 that contacts the guide rail 5 in rolling contact with the guide rail 5, in which the guide rail 5 extends rearward beyond the rear side 3B of the opening 3.

That is, the roof side rail 4 is connected to the roof panel 8, as shown in enlarged form in FIGS. 2 and 3.
It is constructed by welding a quarter inner panel 4A and a quarter outer panel 4B to form a closed cross section 4C in the longitudinal direction of the vehicle at the lower position of the side end in the vehicle width direction, and the guide rail 5
In the vehicle longitudinal direction, the quarter outer panel 4B is recessed along the upper side 3A of the opening 3 in the direction of the quarter inner panel 4A (inward direction in the width direction of the vehicle body) into a recess 9 having a substantially U-shaped vertical cross section. In this embodiment, the recess 9 of the quarter outer panel 4B is formed by extending rearward beyond the rear side 3B of the opening 3, that is, the upper end of the quarter pillar 10. .

Reference numeral 11 in the figure indicates a lower position of the side edge of the roof panel 8, which covers the upper part of the opening of the recess 9 of the quarter outer panel 4B, and more specifically, the guide rail 5 in the recess 9. A roof drip channel is shown which is drooped and welded to connect the roof panel 8 and the quarter outer panel 4B so as to cover the roof panel 8 and the quarter outer panel 4B.

In this embodiment, the guide rail 5 is arranged to extend rearward beyond the rear side 3B of the opening 3, so that the front-to-back length of the upper part of the sliding door 1 is as shown in FIG. Even if the length is smaller than the front-to-back length of the lower part, the opening 3 can be slid rearward as far as it can be fully opened.

In the above embodiment, the guide rail 5 extends rearward beyond the rear side 3B of the opening 3, but the present invention is not limited to this, and can be applied to a sliding door of the vehicle. Depending on the arrangement, the guide rail may extend forward. This is applied, for example, to a case where a sliding door at the rear of the vehicle is moved forward to open the door in a large vehicle.

Further, in the embodiment, the rear side 3B of the opening 3
is the position of the quarter pillar 10, but the present invention is naturally applicable to cases where there is no pillar.

Further, the gap 12 for the arm 6 in the above embodiment to be inserted into the recess 9 of the quarter outer panel 4B is the distance between the lower surface of the recess 9 of the quarter outer panel 4B and the lower end of the roof drip channel 11. 1, but this is because the vertical dimension of the gap 12 is set to the minimum width so that the arm 6 does not interfere with the quarter outer panel 4B and the roof drip channel 11, so the appearance of the vehicle does not deteriorate. That is, most of the guide rail 5 is covered by the hanging roof drip channel 11, so that it is hardly noticeable that it extends to the rear of the door opening.

In addition, in the above embodiment, the guide rail 5
extends over its entire length inside the recess, and guides the roller 7 by the surface 9A of the recess facing the roof drip channel and the inner surface 11A of the roof drip channel 11. , all or part of the guide rail 5 may be omitted (see FIG. 3). In this case, weight and cost can be reduced.

Since the present invention is configured as described above, the front-to-back length of the sliding door is not limited by the length of the guide rail, and therefore the sliding door can be installed on vehicles with shapes that have been difficult to install in the past. Alternatively, the degree of freedom in designing the sliding door can be greatly increased, and the appearance of the vehicle is not deteriorated, which is an excellent effect.
