Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a seat belt reinforcement structure.

0002

[Conventional technology]

Seat belts are the cheapest and most effective device to protect passengers. This is well known. Seat belts include two-point seat belts and three-point seat belts. There are two-point belts (waist belts) and shoulder belts. The three-point seat belt combined with The webbing on the shoulder belt and waist belt is continuous to make it higher and easier to use. The method is becoming popular.

0003 A three-point seat in which the webbing of the shoulder belt and waist belt of the front seat are continuous. The belt generally has one end attached to the side sill via the anchor and the other end attached to the top of the center pillar. It passes through the attached guide ring to the retractor installed at the bottom of the center pillar. attached, and the area near the waist is removably connected to the buckle stalk via the buckle. It has become so. The guide ring is welded to the upper part of the center pillar. It is firmly attached to the fixed seat belt reinforcement with bolts.

[Problem that the idea aims to solve]

By the way, the center pillar has two parts on each side of the outer center pillar and the inner center pillar. The provided flange part is welded to form a box cross-sectional structure, but the center There is a structure in which the flange at the top of the tapira is removed to make the top part look thinner. Ru. However, the center pillar with this structure has a slender upper part with a seatbelt for the front seats. In order to attach the guide ring of the The connecting part between the lower part of the thick cross-sectional structure with a flange and the upper part of the thin cross-sectional structure without a flange. Because the cross section changes rapidly in the There is a problem that the rigidity of the pillar as a whole is low.

[0005] This idea was made in view of the above points, and the center pillar has a slender upper part. to increase the strength of the seat belt attachment part and to strengthen the entire center pillar. The aim is to provide a seatbelt reinforcement structure that increases the rigidity of the seatbelt. target

[0006]

[Means to solve the problem]

In order to achieve the above object, according to the present invention, approximately the upper half of the upper part is of the slender type. The seat belt reinforcement attached to the upper part of the center pillar is inserted from the upper part. The center pillar outer and center pillar outer of the center pillar are also slightly longer. The structure is such that it is integrally welded to the reinforcement and side roof rails.

[0007]

[Effect]

The center pillar has an integrated seat belt reinforcement that spans the entire length of the slender upper part. The center pillar is fixed by welding, which increases the rigidity of the upper part and improves the system. The strength of the seat belt attachment part is improved, and the overall rigidity is also improved.

[0008]

【Example】

An embodiment of the present invention will be described below in detail with reference to the accompanying drawings. In FIG. 1, the center pillar 1 has a center pillar outer 2 and a center pillar outer ring. The center pillar outer 2 is composed of a force 3 and a center pillar outer 2 from approximately the center to the upper half. The upper part 2a of the lower half is thinner than the lower part 2b of the lower half, and the lower part 2b has flanges on both sides. 2c, 2c (FIG. 4) are provided. And above this center pillar outer 2 The portion 2a is formed in a mountain shape along the longitudinal direction. In addition, the upper part 2 of center pillar 2 a is the window part of the door.

[0009] The center pillar outer reinforcement area 3 is similar to the upper part 2a of the center pillar outer 2. The lower end 3b is narrower and slightly longer than the upper part 2a. It is wide like the central part 2d of the Tapira outer 2, and has flanges 3c, 3c on both sides. It is formed. This center pillar outer reinforcement 3 is entirely It is formed in a mountain shape along the longitudinal direction, and the end surface 3a is the center pillar outer. It can be fitted into the upper part 2a of 2.

0010 The length of the seat belt reinforcement 4 is approximately the center pillar outer reinforcement. 3, and its width is approximately the inner diameter of the center pillar outer force 3. The dimensions are the same, and both sides 4a, 4a except for the lower end 4b have a C channel structure. (FIG. 3), and the lower end 4b has a U-channel structure (FIG. 4). So This seatbelt reinforcement 4 has a seatbelt guide at a predetermined location at the top. A bolt hole 4c for attaching a door ring is provided.

[0011] In addition, the side roof rail 5 has a side roof rail outer 6 and a side roof rail outer 6. The side roof rail outer 6, the side roof rail outer 6, and the flail inner 7, Flanges 6a, 6a, 7a, and 7a are provided on both sides of the idle rail inner 7, respectively. It is formed. Then, side roof rail outer 6 and side roof rail inner The flanges 6a, 6a, 7a, 7a of the inner 7 are welded to form the side roof rail 5. It is formed.

0012 The center pillar outer reinforcement 3 fits inside the center pillar outer 2 (Fig. 3 , Fig. 4), and the end surface 3a is attached to the inner surface of the upper part 2a of the center pillar outer 2 for an appropriate distance. The lower end 3b and flanges 3c, 3c are welded at intervals of the center pillar outer 2. It is welded to the center portion 2d and the flanges 2c, 2c. In this way the top is the bottom A very thin center pillar 1 is formed.

[0013] In addition, the seat belt reinforcement 4 is installed at the center pillar as shown in FIGS. 3 and 4. It is fitted inside the outer reinforcement 3, and both side parts 4a, 4a are the center pillar outer They are welded to both sides of the reinforcement 3 by spot welding at appropriate intervals. Also, The lower end 4b of this seat belt reinforcement 4 is a center pillar outer reinforcement. It is welded to the lower end 3b of 3. In fact, these center pillar outer 2, center The pillar outer reinforcement 3 and the seatbelt reinforcement 4 are welded at the same time. Ru.

[0014] The upper ends of the center pillar 1 and the seat belt reinforcement 4 are shown in FIG. The lower end of the center pillar 1 is integrally welded to the side roof rail 5 as shown in FIG. It is welded and fixed to the idle shell (not shown). This allows center pillar 1 to It is firmly fixed between the roof rail 5 and the side shell. And the sheet The guide ring of the front seat seat belt is inserted into the hole 4c at the top of the belt reinforcement 4. It is attached by a bolt (none of which is shown).

[0015] The slender upper part of center pillar 1 has seatbelt reinforcement 4 along its entire length. Because it is reinforced, the rigidity is significantly improved and it is less susceptible to vibrations or seat belts. Even if a force is applied inward or outward as indicated by arrows F or F' in Figure 2, it will not deform. There is no such thing. Therefore, the upper part of center pillar 1 can be made even more slender than before. Becomes Noh. In addition, the rigidity of the connecting part between the slender upper part and the wider lower part of center pillar 1 has also been improved. Moreover, the rigidity of the center pillar 1 as a whole is also improved.

[0016]

[Effect of the idea]

As explained above, according to the present invention, the upper part of approximately the upper half is of the slender type. The seat belt reinforcement attached to the upper part of the pillar is slightly smaller than the upper part. The center pillar outer and center pillar outer lymph of the center pillar are formed long. Since the structure is integrally welded to the base and side roof rails, the center pin The upper part of the car has increased rigidity, providing sufficient strength to withstand vibrations and input from seatbelts. The upper part of the center pillar can be made thinner, and This has the effect of increasing the rigidity of the entire center pillar.
