Description

A kind of front-row occupant air bag

Technical field

The utility model relates to vehicle passive safety engineering device technique field, specifically a kind of front-row occupant substitute Capsule.

Background technique

It is most of riding at present with the development of raising and automotive safety technology itself that consumer requires automotive safety Vehicle is all using front-seat air bag as the standard configuration of vehicle.For front-seat air bag, especially copilot's air bag For, generally comprise the parts such as housing assembly, airbag, generator, retaining ring, stud, dust cover.Referring to Fig. 1, shell 4 is often Comprising the lower bracket assembled with bodywork parts CCB bracket, shell 4 and lower bracket connection type it is general there are two types of:

Referring to fig. 2, the first is two independent lower brackets of design, passes through TOX rivet or weld with main casing part Mode forms housing assembly.Since lower bracket and the fixed position of CCB bracket are closer to, space is limited, and lower bracket designs increasingly It is similar, the means such as a large amount of physics mistake proofing, image mistake proofing need to be put into Shell Manufacture and air bag module assembly technology go to control System welds or rivets the probability of wrong part.

Referring to Fig. 3, second is to design free-standing lower bracket, is assembled with main casing part by four studs in retaining ring Together, then by four urgent modes of nut it assembles.It is additional to increase lower bracket part in module assembling process, increase Assembly man-hour.And free-standing lower bracket need to design housing bottom center and stud to face, increase shell Weight and cost.

Referring to Fig. 1, each component assembly process of air bag device is as follows:

1, retaining ring 3 is first filled in 2 installing port part interior of airbag, stud is then encased on airbag 1 corresponding holding In ring stud pilot hole.

2, airbag 2 is folded up using equipment and tooling, wraps up airbag 2 and retaining ring 3 with dust cover 1, it is total folding At filling in shell 4.

3, the generator stud bolt hole correspondence of gas generator 5 is encased on the stud of retaining ring 3.

4, the assembly of air bag device is completed with 6 fixed bolt of fastener.

That there are parts is more for this traditional design, assembly man-hour is longer, lower bracket mistake proofing is poor and product is heavier asks Topic.

Therefore, it is necessary to design the front-row occupant air bag that a kind of assembly is simple and quality is stable.

Summary of the invention

It is simple the purpose of the utility model is to overcome the deficiencies of the prior art and provide a kind of assembly and quality is stable Front-row occupant air bag.

In order to achieve the above object, the utility model is a kind of front-row occupant air bag, including airbag, retaining ring, under Bracket, gas generator, fastener, retaining ring are located at the inside of airbag, and folded airbag is located at the surrounding of retaining ring within the walls, It is characterized by: the retaining ring for being equipped with airbag is fixed on lower bracket, the stud of retaining ring sequentially pass through airbag, lower bracket, It after gas generator, is connect with fastener, the forward and backward side of lower bracket is integrated with hook respectively, and hook is assembled with instrument board window Connection.

The lower bracket is equipped with the stabilizer blade extended downwardly, and the surface of stabilizer blade is matched with the direct face of vehicle body pipe beam.

The stabilizer blade is located at the left and right both ends of sub-mount frontside.

The surface of the stabilizer blade is equipped with through-hole, and center is aligned and the company of assembly between through-hole and remote vehicle body pipe beam hole It connects.

The inside of the stabilizer blade is equipped with convex block, and the boundary of convex block and stabilizer blade is equipped with through-hole, through-hole and short distance vehicle body Center alignment and assembly connection between pipe beam hole.

Compared with the prior art, the utility model designs the bracket air bag knots integrated and without shell with hook Structure, when assembly, reduce TOX or welding sequence etc., improve assembly efficiency, and do not need individually designed, management lower bracket zero Part while mitigating weight, improves mistake proofing.The utility model effectively realizes the allomeric function of air bag, and reach with The comparable performance of the prior art has Cost And Performance double dominant.

Specific embodiment

The utility model is described further now in conjunction with attached drawing.

Embodiment 1

Referring to fig. 4, the front-row occupant air bag in this example includes airbag 2, retaining ring 3, lower bracket 7, gas generator 5, fastener 6.

Referring to Fig. 5, the assembly method of airbag 1 and retaining ring 2 is in this example, and retaining ring 2 is filled in inside airbag 1, with setting It is standby to fold, so that folded airbag 2 is filled in retaining ring surrounding within the walls, puts quick-fried process, large scale retaining ring and matching gas The design of capsule frame can guarantee that airbag 2 will not scatter from periphery.

In this example, the retaining ring 3 for being equipped with airbag 2 is fixed on lower bracket 7, and the stud of retaining ring 3 sequentially passes through airbag 2, it after 7 gas generator 5 of lower bracket, is connect with fastener 6, not only can guarantee that airbag 2 and the flexible assembly of lower bracket 7 are connect, And its connection has comparable intensity, can make air bag device when bearing work because gas generator 5 is inflated outward and gas Bag 2 expands outward and the impact force of generation, guarantees to be separated from each other between airbag 2 and lower bracket 7.

Referring to Fig. 6, the forward and backward side of lower bracket 7 is integrated with hook, hook and instrument board window assembly connection respectively.Lower branch Frame 7 is turned down from bottom surface both side, then is turned down, and the hook of the forward and backward side of shell is cut, is stamped and formed out, and hook dimensions can maintain former tradition Design, to facilitate opponent's part not repair a die, directly continues to use, meets matching requirements.Lower bracket 7 uses grading mold technique one-pass molding, Without mistake proofing problem, and design simple, light-weight.

According to assembly needs, the lower bracket 7 of integrated hook function is equipped with the stabilizer blade 8 extended downwardly, and stabilizer blade 8 is located at lower bracket The left and right both ends of 7 front sides.The surface of stabilizer blade 8 is matched with the direct face of vehicle body pipe beam.Vehicle body pipe Liang Zhi is corresponded on the surface of stabilizer blade 8 Central hole location setting through-hole 9 is connect, center is aligned simultaneously assembly connection between through-hole 9 and remote vehicle body pipe beam hole.

This example is suitable for vehicle body Guan Liang apart from farther away design.

Embodiment 2, the difference part with previous embodiment is only described in this example, and same section is not repeated to illustrate.

Referring to Fig. 7, the lower bracket 7 of integrated hook function is equipped with the stabilizer blade 8 extended downwardly, and the inside of stabilizer blade 8 is equipped with convex block, The boundary of convex block and stabilizer blade 8 is equipped with through-hole 9, and center is aligned simultaneously assembly connection between through-hole 9 and short distance vehicle body pipe beam hole.

This example is suitable for the design that vehicle body Guan Liang is closer.

In this example, the angle of stabilizer blade 8 and the position of through-hole 9 and vehicle body are to matching face structure matching, the angle of stabilizer blade 8 and logical The position in hole 9 can be adjusted according to vehicle body to face structure.

This example design scheme can satisfy the performance requirement of air bag.

Above-described embodiment is copilot's air bag, is passed through by airbag 2, retaining ring 3, lower bracket 7, gas generator 5 Fastener 6 assembles, impact when being able to bear air bag device work to above-mentioned each part and its connecting portion, effectively It realizes the allomeric function of air bag device, and reaches and the comparable performance of the prior art.
