Description

[Detailed description of the invention] (Industrial application field) The present invention relates to the pillar structure of an automobile, and more specifically, a through anchor is attached to the upper part of the center pillar, and a seat belt is inserted through the through anchor. The present invention relates to a pillar structure that reduces wind noise from seatbelts in automobiles.

(Prior art) Seat belts installed in automobiles are generally passed around a through anchor attached to a center pillar and retracted by a retractor installed below the through anchor. Between the retractor and the retractor, it is placed in a state where it is stretched along the center pillar.
(Refer to Publication No. 58-22150) (Problem to be solved by the invention) For this reason, when driving with the door windows open, the wind blowing into the interior of the vehicle body creates a gap between the through anchor and the retractor. There is a problem with the seatbelts being tightened and flapping, which causes wind noise.

In particular, for automobiles equipped with triangular windows on the front doors, the flow velocity of the traveling air blown into the vehicle interior is large due to the effect of separation vortices that occur when the triangular windows are opened, and as a result, the seat belt There is a problem in that the fluttering and wind noise are noticeable.

The present invention was developed in consideration of the above problems, and its purpose is to reduce the flapping of the seatbelt stretched between the through anchor and the retractor and the generation of wind noise. The purpose of this research is to propose a structure for the pillar part of an automobile.

(Means and effects for solving the problem) The present invention includes a through anchor attached to a center pillar, a retractor disposed below the through anchor, and a seat inserted through the through anchor. Assuming that the vehicle is such that the belt is wound up by the retractor, a rectifying member is provided on the inside of the vehicle of the center pillar, and the rectifying member is connected to the seat belt stretched between the through anchor and the retractor. It is configured to extend in the vertical direction along the front edge of the.

With this configuration, the wind blowing into the vehicle interior is deflected by the rectifying member,
It flows away to the gazette without directly exciting the seatbelt.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

The automobile A shown in FIG. 2 is of the so-called cabriolet type with the upper and rear parts of the passenger compartment open, and the soft top 1 that covers the upper and rear parts of the passenger compartment is folded and stored in the rear part of the passenger compartment. It's getting old. In the figure, 2 is a front door, 3 is a door window, and 4 is a quarter window that can be raised and lowered.
The center pillars 5, 5, which are sandwiched between the It has improved safety. Further, the front door 2 is provided with a triangular window 7 in front of the door window 3, which can be raised and lowered. It is designed to be able to be installed inside the vehicle body.

The seatbelt for the front seat is a so-called three-point type, and the seatbelt 8, which is placed across the upper body of the seated person, is passed over a through anchor 9 attached to the center pillar 5, and is attached below the through anchor 9. It is adapted to be wound up by a retractor (not shown) provided in the.

FIGS. 1, 3, and 4 show a center pillar trim upper 11. The center pillar trim upper 11 is located inside the center pillar 5, which is composed of a center pillar outer 5a and a center pillar inner 5b. (located on the passenger compartment side). In FIG. 3, 12 is a through anchor mounting hole.

A flow regulating member 13 is integrally formed on the front side of the center pillar trim upper 11, and the flow regulating member 13 has a smooth flow surface shape from the front side of the vehicle body (the right side when facing in Figs. 1 and 3). have,
The through anchor mounting hole extends from a slightly lower position to the belt line (BL). That is, the center pillar trim upper 11 extends along the front edge above the belt line (BL) of the seat belt 8 stretched between the through anchor 9 and the retractor. Although not shown, through anchor 9
Of the seat belt 8 stretched between the vehicle and the retractor, the portion below the belt line (BL) is covered by a center pillar trim lower.

In the above configuration, when driving with the door window 3 or the triangular window 7 open, the wind blowing into the vehicle interior is deflected from the state shown by broken line C in FIG. It will flow backwards without exciting the belt 8.

FIG. 5 shows the test results of the wind noise reduction effect of the seat belt, and the test conditions were as follows.

Vehicle speed: 80km/h With door window fully open: Seaton belt 8 present, rectifying member 13 absent. ; With seat belt 8, without rectifying member 13 △; Length of rectifying member 13 (L shown in FIG. 3);
L = 130 mm ×; L = 200 mm The length of the seat belt 8 stretched between the through anchor 9 and the retractor is 130 mm above the belt line (BL). Also,
The height (H) of the rectifying member 13 is such that it protrudes from the seat belt 8 toward the interior of the vehicle by approximately 2.0 mm.

As is clear from the test data shown in Figure 5,
Due to the presence of the rectifying member 13, an overall sound reduction effect of approximately 5 dB is observed.

6 to 9 show other embodiments, and the same elements as in the first embodiment are given the same reference numerals, and their explanations will be omitted.

6 and 7 show a second embodiment. In this embodiment, the flow regulating member 13 is formed by extending the front side part of the flow regulating member 13 upward at the upper end of the center pillar trim lower 14. The flow regulating member 13 has a curved shape convex toward the front side of the vehicle body, and the base end 13a of the flow regulating member 13 is fitted into the seaming welt 15.

FIGS. 8 and 9 show a third embodiment. In this embodiment, a tongue piece 16 that projects toward the interior of the vehicle is integrally formed on the seaming welt 15, and the tongue piece 16 rectifies the flow. It constitutes the member 13.

The embodiments of the present invention have been described above, but as a wind noise prevention means for the seat belt 8, in addition to the above embodiment, the seat belt 8 stretched between the through anchor 9 and the retractor can be trimmed by center pillar trim. It is also conceivable to cover the whole with 11 and 14. However, when such a method is used, the center pillar trim upper 11 also has a shape that bulges into the vehicle interior, which is not preferable because it gives a feeling of narrowing the vehicle interior space. In contrast, according to the present invention, the center pillar trim upper 11
This has the advantage that the wind noise of the seat belt 8 can be reduced without spoiling the feeling of spaciousness in the vehicle interior.

(Effects of the invention) As is clear from the above explanation, according to the invention, the wind blowing into the vehicle interior is deflected by the rectifying member and flows backwards without exciting the seatbelt. can reduce flapping and wind noise.
