DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear pillar structure for a vehicle.

[0002]

2. Description of the Related Art As a conventional vehicle rear pillar structure,
For example, the one shown in FIGS. 2 and 3 is known [for a similar technique, see page D-54 of "New Car Manual" (C34-1) issued in January 1993 by Nissan Motor Co., Ltd.]. In the figure, A is the front side and B is the rear side.

Reference numeral 1 denotes a rear pillar, which has a closed cross-sectional structure in which a rear pillar outer 2 and a rear pillar inner 3 are joined. That is, the rear pillar outer 2 has an outer surface portion 4 exposed to the outside of the vehicle at substantially the center, and a stepped portion 2a before and after the outer surface portion 4 is provided.
2b are formed.
The front and rear end portions 3a and 3b of the rear pillar inner 3 are joined to the inner end b, respectively. A rear window panel 5 is provided on a rear stepped portion 2b on the rear side of the rear pillar outer 2 via a weather strip or a molding (not shown). The window panel 6 is made to correspond via a weather strip (not shown).

A rear pillar garnish 7 is provided on the vehicle interior side of the rear pillar inner 3, and large and small mounting holes 8, 9 corresponding to the rear pillar garnish 7 and the rear pillar inner 3, respectively, are formed. And
A welding nut 10 is provided inside a mounting hole 9 as a “mounting portion” of the rear pillar inner 3, and a fixing bolt 12 screwed to the welding nut 10 via a spacer 11 is provided.
A through ring 14 as a “support member” for the seat belt 13 is attached.

[0005]

However, in such a conventional technique, since the through ring 14 for the seat belt 13 is attached to the rear pillar inner member 3, the through ring is taken into consideration in consideration of the occupant restraint. Even if it is desired to set the mounting position of the ring 14 further rearward, the ring 14 can be moved only to the rear end 3b of the rear pillar inner 3. In addition, if the front-rear size of the entire rear pillar 1 is increased, the mounting position of the through ring 14 can be set further rearward. Then, the front-rear width of the outer surface portion 4 of the rear pillar outer 2 exposed to the outside of the vehicle is reduced. Becomes large, which is not preferable in appearance quality.

The present invention has been made by paying attention to such a conventional technique, and the mounting position of the seat belt support member is set to a rear side without changing the width of the outer surface portion of the rear pillar outer. And a rear pillar structure of the vehicle.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, a rear pillar structure for a vehicle according to the present invention extends a stepped portion at a rear side of a rear pillar outer and a rear end of a rear pillar inner to a rear side. By doing so, the mounting portion of the seat belt support member is formed on the rear pillar inner rear portion of the rear pillar outer outer surface portion.

[0008]

According to the rear pillar structure of the vehicle of the present invention, the rear stepped portion on the rear side of the rear pillar outer and the rear end of the rear pillar inner are extended to the rear side, respectively, so that the rear pillar outer is less than the rear pillar outer surface. Since the mounting portion of the seatbelt support member is formed at the rear side position, the mounting position of the seatbelt support member can be set to a rear side as compared with the conventional case by mounting the seatbelt support member at this mounting portion. Becomes possible. Moreover, in the rear pillar outer, only the rear step-down portion extends to the rear side, and the outer surface is not changed, so that the appearance quality is not deteriorated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to FIG. In addition, the description which overlaps with the related art is omitted.

In the rear pillar 15 of this embodiment, a stepped portion 16b on the rear side of the rear pillar outer 16 and a corresponding rear end 17b of the rear pillar inner 17 extend to the rear side. By extending the rear pillar inner 17 to the rear side in this way, the rear pillar inner 17
Accordingly, the front and rear width of the rear pillar garnish 18 that covers the rear pillar inner 17 is also increased. Rear pillar 15 of this embodiment
Only the rear step 16b and the corresponding rear end 17b extend to the rear, and the other front step 16a, the outer surface 19, and the rear end 17a are substantially the same. It has a conventional shape.

In the rear pillar inner 17, a mounting hole 20 is formed at a position behind the outer surface portion 19 of the rear pillar outer 16 as a “mounting portion”,
A welding nut 21 is mounted inside the mounting hole 20 as before. A mounting hole 22 having a slightly larger diameter is formed in a portion of the rear pillar garnish 18 corresponding to the mounting hole 20, and a fixing bolt 24 is screwed into the welding nut 21 via a spacer 23 therefrom. Fixing bolt 2
4 is provided with a through ring 25 as a “support member”.

As described above, in this embodiment, since the through ring 25 is located on the rear side as compared with the related art, the restraint of the occupant by the seat belt 26 is improved accordingly. In addition, while the position of the through ring 25 is moved to the rear side, the position and the width of the outer surface portion 19 exposed to the outside of the vehicle remain unchanged, so that the appearance quality of the vehicle is impaired. Nor. In addition, as described above, since the width of the rear step-down portion 16b corresponding to the rear window panel 27 is larger than in the related art, the mounting rigidity of the rear window panel 27 is also increased.

In the above description, an example in which the rear side window panel 28 which can be moved up and down is provided corresponding to the stepped portion 16a on the front side of the rear pillar outer 16, but a fixed corner called a so-called triangular window is provided. The shape may be a rear side window panel.

Further, the seat belt 26 of the type which is entirely exposed to the vehicle interior is taken as an example, and the through ring 25 is taken as an example of the "support member". However, the present invention is not limited to this. 26 is provided with a retractor that winds and accommodates 26, and a “supporting member” is provided on the rear pillar inner 17.
An escutcheon (not shown) may be provided, and the seat belt 26 in the rear pillar 15 may be drawn out of the escutcheon toward the vehicle interior.

[0015]

The rear pillar structure of the vehicle according to the present invention has the contents as described above, and the stepped portion on the rear side of the rear pillar outer and the rear end of the rear pillar inner are respectively extended to the rear side. Thus, the mounting portion of the seat belt support member is formed at a position behind the outer outer surface portion of the rear pillar inner of the rear pillar inner. By attaching the seat belt support member to this mounting portion, the seat belt support member is provided. Can be set at a rear side of the conventional position. Moreover, in the rear pillar outer, only the rear step-down portion extends to the rear side, and the outer surface is not changed, so that the appearance quality is not deteriorated.
