Referring to these drawings, since the pillar anchor 100 for automobiles according to the present embodiment can be manufactured simply by breaking away from the conventional complex structure, the manufacturing cost can be significantly reduced.

In addition, the pillar anchor 100 for automobiles according to the present embodiment can increase durability and significantly reduce weight compared to the prior art, so it can be easily applied to electric vehicles requiring lightweight parts.

In particular, the pillar anchor 100 for a vehicle according to this embodiment is provided with a reinforcement flange 130 as described later to serve as a strong support, so that the pillar anchor 100 for a vehicle is deformed even in a very strong impact during a vehicle collision or collision. It is possible to stably support a seat belt (40, seat belt) of the vehicle without being damaged, and as a result, it is possible to safely protect the driver or passengers.

The pillar anchor 100 for a vehicle according to the present embodiment that can provide such an effect includes an anchor body 110, and the following components are formed and processed for each position in the anchor body 110.

As such, the pillar anchor 100 for automobiles according to the present embodiment can be manufactured simply because the anchor body 110 of a single plate type is used, and thus the manufacturing cost and weight can be significantly reduced. In addition, durability can be increased due to the structural features below.

The pillar anchor 100 for a vehicle of this embodiment is mounted on a vehicle in the same manner as in FIG. 1 to guide the movement of the vehicle seat belt 40 . That is, when the seat belt 40 is worn, the seat belt 40 must be pulled, and when the seat belt 40 is unwound, the seat belt 40 must be rewound to its original state. The pillar anchor 100 for automobiles is in charge.

Since the seat belt 40 is one of the important safety devices in a vehicle, in order to stably guide the seat belt 40 while supporting the seat belt 40, a pillar anchor 100 for a vehicle guides the movement of the seat belt 40. ), that is, the durability of the pillar anchor 100 for automobiles including the anchor body 110 should be high.

However, if the filler anchor 100 for automobiles is manufactured by a method with a complicated structure or manufacturing method as in the past, for example, after primary processing with a thick steel plate, and then inserting a synthetic resin secondary, the process is inevitably complicated, The manufacturing cost is inevitably high, and in particular, it is inevitably high in weight, so it may not be in line with the trend that demands weight reduction of parts like recent electric vehicles.

In particular, considering that injection molding is decreasing due to recent environmental problems, it may be the optimal method to manufacture the anchor body 110 from one sheet of metal as in the present embodiment.

However, in the case of manufacturing and welding the anchor body 110 with only a simple shape, the anchor body 110 is manufactured to have the following structural characteristics in that the desired structural strength cannot be provided.

In this embodiment, the anchor body 110 may be made of a metal material. Let's take a closer look at this. In this embodiment, the anchor body 110 may be obtained by processing an iron plate provided in a roll type into a desired shape. Since the roll-type iron plate is used in this way, a continuous process is possible, which can increase productivity.

In this case, the applied iron plate may be high tensile steel for automobile structure. The use of high-tensile steel for automobile structures has the advantage of being able to apply a thin thickness and increasing strength and tensile strength.

For reference, if you ride a car for a long time, pollution occurs inside the vehicle by cigarette smoke, other foreign substances, or outside air. At this time, when the filler anchor 60 is manufactured as an injection-molded material as shown in FIG. 1 , contaminants are adhered to the surface of the filler anchor 60 due to the characteristics of the injection-molded material, thereby limiting the movement of the seat belt 40 made of fibers. In other words, contaminants may adhere to the surface of the filler anchor 60 made of the injection material, or the contaminants may react with the injection material to make the surface of the filler anchor 60 rough. In this case, the seat belt 40 is soft and It inevitably causes a lot of trouble in moving flexibly, which can soon cause safety problems. However, if the filler anchor 100 is made of metal rather than injection molding as in the present embodiment, the above problem can be completely solved because contaminants do not stick well and can easily fall off.

A belt movement guide groove 120 is formed in the anchor body 110 . The belt movement guide groove part 120 is formed to protrude to one side of the anchor body 110 through drawing processing, and serves to guide the movement of the seat belt 40 .

Here, the drawing process is an operation of making, for example, a hemispherical protrusion by pressing a flat iron plate from one side. In the present embodiment, the belt movement guide groove 120 protruding from the anchor body 110 is formed through drawing processing.

In this embodiment, the belt movement guide groove 120 has an elliptical structure of a closed loop. The belt movement guide groove part 120 is substantially spaced apart from the belt contact support part 123 to which the seat belt 40 is contacted and supported, the belt contact support part 123 and the opposite side of the belt contact support part 123, It may include a belt guide part 121 for guiding movement of the seat belt 40 together with the contact support part 123 , and a connection part 122 for connecting the belt contact support part 123 and the belt guide part 121 . .

At this time, in the present embodiment, during the drawing processing of the anchor body 110, the belt movement guide groove part 120 has a progressively higher degree of protrusion toward the belt guide part 121, the connection part 122, and the belt contact support part 123. do.

This is because the portion where the seat belt 40 is contacted and supported is the belt contact support part 123 , so it must be formed at the widest and deepest part to widen the contact area with the seat belt 40 to stably support the seat belt 40 . to do

In the inside of the belt movement guide groove portion 120, the belt passage hole 140 is formed to penetrate. In other words, the belt passage hole 140 through which the seat belt 40 passes is formed in the anchor body 110 to the inside of the belt movement guide groove 120 .

The belt passing hole 140 takes the shape of a long rectangular hole, and the belt guide rib 150 is provided in the belt passing hole 140 area.

The belt guide rib 150 takes a shape protruding to the inside of the belt passage hole 140 . The belt guide rib 150 serves to prevent the seat belt 40 passing through the belt passage hole 140 from overturning.

Of course, since the belt guide rib 150 is not necessarily formed, it should be said that the pillar anchor (not shown) without the belt guide rib 150 also falls within the scope of the present invention.

The anchor body 110 has a vehicle body fixing part 112 formed in one corner area. The vehicle body fixing unit 112 forms a fastening place for bolts used when the automobile pillar anchor 100 is fixed to the vehicle body. In the present embodiment, the vehicle body fixing part 112 is provided in the form of a hole formed to pass through the anchor body 110 .

For reference, in the case of the pillar anchor 100 for automobiles of this embodiment, the portion with the vehicle body fixing part 112 is curved forward or backward, which is one for facilitating the installation of the pillar anchor 100 for automobiles. may be a way of Therefore, if the pillar anchor 100 for a vehicle can be installed well, there is no need to bend the part where the vehicle body fixing part 112 is located forward or backward. That is, unlike the drawings, the anchor body 110 may be made of a flat plate-like body, and it should be said that all of these matters fall within the scope of the present invention.

On the other hand, the reinforcement flange 130 for reinforcing the anchor body 110 is formed at the end of the anchor body 110 in the pillar anchor 100 for automobiles of this embodiment.

The reinforcing flange 130 is continuously arranged along the outer periphery of the belt movement guide groove portion 120 as a kind of reinforcing material, and serves to reinforce the rigidity of the pillar anchor 100 for automobiles.

This will be described in detail. In the event of a vehicle collision or collision, a strong force to support the driver or occupant is momentarily concentrated toward the belt contact support portion 123 of the belt movement guide groove portion 120 through the seat belt 40, in particular, the seat belt 40. (100), if there is no reinforcing flange 130, the pillar anchor 100 for automobiles may be bent or damaged, and furthermore, the seat belt 40 may be cut, resulting in a very dangerous situation.

However, in the case of this embodiment, since the reinforcement flange 130 is applied to the pillar anchor 100 for a vehicle, the force that is momentarily concentrated toward the belt contact support part 123 of the belt movement guide groove part 120 through the seat belt 40 can offset the problem that the pillar anchor 100 for automobiles is bent or damaged. Therefore, it is possible to increase the durability of the pillar anchor 100 for automobiles to extend the life.

In this case, the reinforcing flange 130 is not formed separately. That is, when forming the belt movement guide groove 120 in the anchor body 110 through the drawing process, the reinforcement flange 130 can be naturally formed by processing it inward by a predetermined distance from the end.

Hereinafter, a method for manufacturing the pillar anchor 100 for automobiles using the anchor body 110 of one sheet will be described.

First, a metal, that is, an anchor body 110 applied with high tensile steel for automobile structure is prepared (S11). The anchor body 110 before processing is provided in a roll type, which can be appropriately cut and used.

Next, the anchor body 110 in the form of a flat iron plate is drawn to form a belt movement guide groove 120 protruding in a hemispherical shape (S12). As described above, the anchor body 110 of the belt movement guide groove 120 may be formed through the drawing process. At this time, the belt contact support 123 is processed in the widest and most protruding form. Here, since the first drawing does not mean the first drawing processing, the number of times is irrelevant.

After forming the belt movement guide groove 120 in the anchor body 110 through such a drawing process, the reinforcing flange 130 may be naturally formed at the end of the anchor body 110 . The reinforcing flange 130 serves to reinforce the anchor body 110 as a rib formed on the outside of the belt movement guide groove 120 .

At this time, the reinforcing flange 130 is continuously disposed along the outer circumference of the belt movement guide groove 120 . Therefore, it is very advantageous to reinforce the strength of the pillar anchor 100 for automobiles.

Next, the anchor body additional processing step (S13) proceeds. Through this step, the belt passing hole 140 , the vehicle body fixing part 112 , etc. may be formed in the first anchor body 110 . As a result, components formed on the anchor body 110 in addition to the belt movement guide groove 120 may proceed through the anchor body additional processing step (S13).

For reference, in the case of this embodiment, the anchor body additional processing step (S13) is shown and described as being performed after the drawing processing step (S12), but the anchor body additional processing step (S13) is to be performed before the drawing processing step (S12) It may be possible, but it should be said that all of these matters fall within the scope of the present invention.

Next, in order to remove burrs that may occur during the drawing processing step or the additional processing step, the drawing-processed anchor body 110 is barrel polished (S14).

In particular, if there is a burr in the area of the belt passage 140 where the seat belt 40 comes into contact, there is a high risk that the seat belt 40 made of cloth may break while the seat belt 40 moves. Therefore, barrel grinding is performed to remove possible burrs.

Of course, the area through which the seat belt 40 passes may be smoothly processed by performing a lapping process or a high-speed drilling process for the same effect instead of berel grinding. For reference, the lapping process refers to the work performed after machining to remove the machining marks or to process the surface roughness of the product exterior into a shiny surface like a mirror.

Then, the anchor body 110 is plated or polished to finish the product by performing a post-processing step (S15).

According to this embodiment, which acts as the structure as described above, since it can be manufactured simply by breaking away from the conventional complex structure, the manufacturing cost can be significantly reduced, durability can be increased, and the weight can be significantly reduced compared to the prior art. can be reduced

In particular, the pillar anchor 100 for a vehicle according to this embodiment is provided with a reinforcing flange 130 as described above in detail and serves as a strong support. It is possible to stably support the seat belt 40 without being deformed, and as a result, it is possible to safely protect the driver or passengers.

10 is a perspective view of a pillar anchor for a vehicle according to another embodiment of the present invention, and FIG. 11 is an enlarged perspective view of the pillar anchor for a vehicle of FIG. One view, Fig. 14 is an image of Fig. 11, Fig. 15 is a front view of Fig. 11, Fig. 16 is a cross-sectional view taken along line B-B of Fig. 15, and Fig. 17 is a pillar anchor for a vehicle according to another embodiment of the present invention. It is a flowchart of the manufacturing method.

Referring to these drawings, the pillar anchor 200 for automobiles according to the present embodiment also uses the anchor body 210 of one plate type, while the belt movement guide groove 220 on the anchor body 210 . , the reinforcing flange 230, the belt passage hole 240, and the belt guide rib 250 are formed and processed for each position. The functions and roles of these configurations are the same as in the above-described embodiment. Therefore, redundant description is avoided. However, since the shapes are different, reference numerals are distinguished in this embodiment.

In this embodiment, the anchor body 210 is not bent to one side, that is, manufactured in a flat shape. Even if it is manufactured in this way, there is no problem in providing the effects of the present invention.

In addition, the belt movement guide groove 220 formed in this embodiment also has an elliptical structure of a closed loop. The belt movement guide groove 220 is substantially spaced apart from the belt contact support 223 to which the seat belt 40 is contacted and supported and the belt contact support 223 to form an opposite side of the belt contact support 223, It may include a belt guide part 221 for guiding the movement of the seat belt 40 together with the contact support part 223 , and a connection part 222 connecting the belt contact support part 223 and the belt guide part 221 . .

At this time, in the present embodiment, during the drawing processing of the anchor body 210, the belt movement guide groove 220 has a progressively higher degree of protrusion toward the belt guide portion 221, the connection portion 222, and the belt contact support portion 223. do. Also, since the portion where the seat belt 40 is substantially contacted and supported is the belt contact support portion 223 , it must be formed at the widest and deepest position to expand the contact area with the seat belt 40 to stably support the seat belt 40 . in order to be able to

On the other hand, a dummy reinforcement part 225 is further formed around the belt movement guide groove part 220 . The dummy reinforcing part 225 is a part that is secondarily drawn to the anchor body 210 adjacent to the belt contact support part 223 constituting the belt movement guide groove part 220, and the seat belt 40 is supported in contact with the belt. It serves to additionally reinforce the contact support 223 .

Of course, among the belt guide part 221 , the connection part 222 , and the belt contact support part 223 constituting the belt movement guide groove part 220 , the belt contact support part 223 is the widest and deepest, so that the seat belt 40 can be stably processed. However, if the dummy reinforcement part 225 is further formed adjacent to the belt contact support part 223 through the secondary reinforcement drawing process, the seat belt 40 due to the action of the dummy reinforcement part 225 . can be supported more stably. Therefore, even if a strong force to support the driver or occupant during a vehicle collision or collision is instantaneously concentrated toward the belt contact support portion 123 of the belt movement guide groove portion 120 through the seat belt 40, in particular, the seat belt 40, the dummy reinforcement Since the part 225 supports this force auxiliary, it is possible to prevent the automobile pillar anchor 200 from being damaged or deformed.

As such, the pillar anchor 200 for automobile according to this embodiment has a dummy reinforcing part 225 that is further applied to the pillar anchor 200 according to the present embodiment, unlike the above-described embodiment. The manufacturing method is the same as in the above-described embodiment, except that a drawing processing step (S12a) for forming the dummy reinforcement part 225 is added therebetween.

Even if applied to this embodiment, since it can be manufactured simply by breaking away from the conventional complex structure, manufacturing cost can be significantly reduced, durability can be increased, and weight can be significantly reduced compared to the prior art.

As such, the present invention is not limited to the described embodiments, and it is apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Accordingly, it should be said that such modifications or variations fall within the scope of the claims of the present invention.
