The present invention relates to a vehicle safety air belt with a built-in airbag that allows the occupant to protect the vehicle from being hit directly by the airbag from the seat belt worn by the occupant in the event of a collision and protects it from other dangerous objects.

In general, as a safety device for protecting passengers by airbags, they are classified electronically or mechanically, and all of them have been developed with a focus on an actuating means for supplying compressed gas to the airbags by detecting them in a fast time. Japanese Utility Model Announcement, such as 63-28044, 63-50203, Pyeongseong 2-2683, and Pyeongseong 2-20127. In addition, in the case of collision, most of the airbags are located with the occupant as the airbag is inflated from the lower part of the vehicle body or from the upper part or the side of the airbag. Is supposed to expand.

This conventional method has the advantage that, when the collision speed of the vehicle is lower than appropriate, the airbag is inflated before the driver hits the vehicle body and is sufficiently positioned in the space between the passenger and the vehicle body to protect the occupant. However, the effect cannot be expected when the occupant is not wearing a seat belt, and especially when the collision speed of the vehicle is higher than appropriate, the effect cannot be expected, especially when the collision speed of the vehicle is higher than appropriate. As a result, the speed at which the occupant collides with the vehicle body is shorter than in the case described above, so that the airbag is inflated and cannot be sufficiently positioned between the occupant and the vehicle body, thereby preventing the occupant from being completely protected.

In addition, the position of the occupant on the seat and the interior, top, bottom, or side of the vehicle should be maintained at a constant correlation with the initial position at which the airbag starts to inflate. As a result, proper and efficient correlation with various passengers is maintained, which prevents the operation of the airbag from being inflated quickly and accurately.In the case of Japanese Utility Model No. 61-11084, only the driver can be protected. As a result, application limits that cannot protect passengers other than the driver were exposed.

In addition, the seatbelt for passengers of the existing vehicle is simply formed in a band form to cover the area of the chest and shoulders together with the abdomen or the abdomen of the occupant. It has the advantage of preventing fatal injury to the occupant, but it simply maintains the band shape, so it does not absorb the shock in the event of an accident and the impact of the reaction is directly applied to the human body. There is a problem that can cause serious damage, such as fractures.

In addition, as a research and development to solve the above problems, there are Japanese Utility Model Publication No. 58-135351 and Japanese Patent Application Publication No. 63-258239. In the former case, the seat belt is not applicable to a general type of seat belt. If not used, there is a disadvantage that it is inconvenient to use because it is not stored inside, and in the latter case, the gas container itself is built in the belt, so it is blown out and stored inside the retractor when the belt is not used. It is difficult to use because it is inconvenient to use and the conductive wire is connected to the outside from the inside of the belt to the sensor part, so there is a problem that a disconnection or short circuit occurs and a malfunction occurs when used for a long time.

The present invention has been made to solve the above-mentioned conventional problems, the air bag inside the belt-type seat belt and the air passage and the air bag inside the belt is momentarily inflated while the operating mechanism is installed separately in the event of a crash In the conventional safety air belt made to protect the, between the air passage portion and the protective sheet of the safety air belt interposed a protective member, in the case of the lock hanger to form a projection having a plurality of recesses in the opening through which the belt passes In the case of the operation mechanism, it is fixed to the side frame of the vehicle body and provides a safety air belt that is installed by exposing only a part of the high pressure hose to the outside to protect the occupant in the event of a collision of the vehicle and to apply it to the usual general safety belt. It is suitable for the following and can be stored inside by the winding part when not in use. If a crash occurs when the occupant is wearing, even though the air passage passes through the lock hanger, the compressed gas can be smoothly supplied to the airbag from the operating mechanism, and the operating mechanism is not exposed to the inside of the body. The purpose is to make the treatment good.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The protrusion 20a is formed, and the operating mechanism 17 is fixed to the lateral frame 8 of the vehicle body, and only a part of the high pressure hose 18 is exposed to the outside through the interior material 5.

At this time, the belt 10 is formed integrally with the air passages (11, 12) and the air bag 13, the both ends of the protective sheet 14 surrounding the air passages (11, 12) is a bar (14b, 14c) Form one side is fixed to the winding portion (1) and the other end is fixed to the fixed end (2), as shown in Figure 3 and 4 the occupant 100 is tied to the belt (10) lock hanger ( When A) is coupled to the lock mechanism 4, the air passage part 11 of the belt 10 is located at the abdomen of the occupant 100, and the weak part 14a at which the airbag 13 is located is at the side of the occupant 100. Located between the shoulders and the air passage 12 is made from the shoulder of the occupant 100 to the hanger (B). In addition, a protective member 15 such as a sponge is inserted between the air passages 11 and 12 and the protective sheet 14, and the rear surface of the air bag 13 is fixed to the inner surface of the protective sheet 14 to operate. The airbag 13 is prevented from detaching from the protective sheet 14.

The lock hanger (A) is made to be locked or unlocked by being inserted into or withdrawn from the lock mechanism (4) as shown in FIGS. 3 and 4, the belt (10) as shown in FIG. The projections 20a having a plurality of recesses 20b are formed in the openings 20 through which the openings 20 pass, and even though the belt 10 is bent while passing through the openings 20, the internal air passages 11 and 12 are formed. When air is supplied by the operating mechanism 17 without being blocked, it is made to be smoothly supplied.

6 is a modified example of the lock hanger A formed by forming a plurality of protrusions 20a and 20c having recessed portions 20b respectively opposite to both sides of the opening 20 so as to face the protrusions 20a. Shows. The winding part 1 is fixedly installed as being embedded between the interior material 5 and the outer frame 6 of the vehicle, and the belt 10 is wound and unwound on the winding part 1 through the opening 7 as in the prior art. It is done to be.

In addition, the actuating mechanism 17 may use the actuating mechanism described in Korean Utility Model Registration Application Nos. 91-19000, 92-463, 92-9087, etc., which is a prior application of the inventors, to operate the safety air belt of the present invention. As long as it is suitable, any other conventional mechanism may be used.

Next will be described in detail with respect to the operation and effects of the present invention as described above.

In the present inventors' safety air belt, as shown in FIGS. 3 and 4, when the occupant 100 pulls the lock hanger A by hand, the belt 10 wound around the winding part 1 is opened. 7) is released through the lock hanger (A) to the lock mechanism (4) is used as a normal seat belt. Of course, when the occupant 100 wants to loosen the belt 10, the lock mechanism 4 is released to separate the lock hanger A, and the belt 10 is opened by the winding unit 1 by itself. It is wound around the winding (1) through.

When the occupant 10 is wearing the safety air belt of the present inventors, an operation mechanism 17 fixed to the lateral frame 8 is operated when a crash or other sudden impact of the vehicle is received from the outside. As the internal high pressure gas is blown out, it is expanded while being instantaneously supplied to the air passage part 11, the air bag 13, and the air passage part 12 through the high pressure hose 18 and the nipple 16. As shown in FIG. 8, the air passages 11 and 12 are expanded in the protective sheet 14 to form an air belt, and the folded airbag 13 is vulnerable to the protective sheet 14 by the expansion force. The 14a is damaged while being exposed to the outside.

Thus, the air passage part 11 is in the form of an air belt in the abdomen of the occupant 100, the air bag 13 is located between the occupant 100 and the body, but cover most of the upper body of the occupant 100, the air passage The part 12 is formed in the form of an air belt between the occupant 100 shoulder and the hanger B to prevent the occupant 100 from directly colliding with the vehicle body and the air passages 11 and 12 and the airbag 100. Due to the characteristics of the air cushion phenomenon is absorbed by the shock is able to protect the occupant 100 safely.

In addition, the airbag 13 is located inside the weak part 14a of the protective sheet 14 at a position from the side of the occupant 100 to the shoulder, and then externally expanded in the vertical direction of the weak part 14a. Since the operating distance is shorter than the method of allowing airbags to appear from the upper, lower, or lateral side of the vehicle body as in the prior art, it is possible to shorten the inflation speed of the airbag and irrespective of various human shapes of the occupant 100. Since the operation is performed in the state where the weak part 14a in which the 13 is located is located at the center of the upper body of the occupant 100, it can always be located at the correct position between the occupant 100 and the vehicle body during operation and greatly improves safety. You can do it.

In addition, air passages (11, 12) are formed on both sides of the air bag (13), and when operated in the form of air belts, unlike the conventional seat belts, it is possible to absorb the shock by the air belts and the abdomen of the passenger 100 The shoulder area can be more securely protected.

In particular, in the case of the safety air belt of the present invention, since the protective member 15 is interposed between the air passage parts 11 and 12 and the protective sheet 14 to form almost the same thickness as the portion where the air bag 13 is embedded. It is suitable to be applied like the existing seat belt and can be stored inside by the winding part 1 when not in use, and in the case of the lock hanger A, a plurality of protrusions 20a and recesses 20b or protrusions 20c are provided. Is formed to smoothly supply compressed gas through the air passage 11, and at the same time, the operation mechanism 17 is installed inside the interior 5 to have an excellent effect such as good finish.
