Definitions
- the present invention relates to a passenger seat airbag device that is provided in a vehicle and that is deployed in the event of a vehicle collision to protect a passenger in a passenger seat.
- an airknob and an inflator are attached to a holding member (for example, a container), and the airbag is further covered.
- the module canopy is installed like this.
- the airplane is activated and the airbag is deployed.
- the module force bar is pushed into the cabin by being pushed by the deployed air knot, and the air knot is deployed largely toward the cabin, thereby protecting the occupant.
- This module cover is provided with a tearing start line (tear line) and a bending start line.
- a tearing start line tear line
- a bending start line When the module is inflated overnight, the module force is reduced. Is pushed or broken by the air knock along these start lines, and opens to the indoor side.
- This type of passenger-side airbag device must be firmly fixed to the vehicle, and the container must be configured so that it will not be deformed by the gas pressure in the airplane. Therefore, the container must be made of a thick metal, and the force is large. Also, this container has a heavy weight The data is fixed before assembling the air knock. As a result, the weight of the container becomes extremely large, and it becomes large when assembling the airbag device (especially, when inserting the folded airbag into the container). Labor was required. In other words, when the folded airbag is to be stored in the container, the container must be completely turned while changing the orientation of the container many times. It is designed to be delivered inside a container, and the heavy container is often moved by hand. However, the installation of the air bag required a large amount of labor, resulting in problems such as severe work fatigue and low assembly efficiency.

- Inflator in the main container 12 1 6 force s fixed.
- the sub-container 20 is inserted into the main container 12, and the airbag 18 is inserted into the sub-container 20 in a folded state. There.
- the sub-container 20 is provided with a through hole 21 so that the gas released from the inflator 16 can pass through the through hole 21 and expand the air bag 18. Has been.
- the main container 12 has a rectangular box shape, and an L-shaped cross-section mounting frame 22 is attached to the inner peripheral edge of the opening on the front side of the main container 12.
- the flange portion 20a of the antenna 20 and the flange portion 18a of the air bag 18 are fixed to the back of the frame 22 with rivets 24, respectively. It has been.
- Reference numeral 18b denotes a cloth (masking cross) provided on the front portion of the air bag 18 and is provided between the air knock 18 and the module cover 14. An air bag 18 is interposed therebetween to prevent the air cover 18 and the module cover 14 from directly touching each other.
- the module cover * 14 has a main body 14a large enough to cover the front opening of the main container 12 and an upper side portion of the main body 14a.
- An upper flange 14b extending rearward from the camera is provided, and a lower flange 14c extending rearward from the lower side of the main body 14a.
- a rib 14d and a groove 14e for facilitating opening of the main body 14a are formed on the rear surface of the main body 14a.
- FIG. 4 which is an enlarged perspective view of the portion IV in FIG. 2
- a convex portion 26 is provided on the lower surface of the upper flange 14 b, and the container 12 is provided with a convex portion 26.
- An opening 28 is formed on the upper surface so that the projection 26 fits.
- the upper flange 14 b and the main container 12 are connected by the rivet 30 after forming the projection 26 and the opening 28.
- the gate 30 connects the frame 22 also to the upper surface of the main container 12 and lays it.
- 30a indicates a rivet hole on the container side
- 30b indicates a rivet hole on the module cover side.
- the module cover 14 has a two-layer structure of a surface layer (inside layer) and a back layer, and the extension of the back layer is provided.
- the rivet hole 30b and the long hole 32 described below are provided at the bottom.
- FIG. 5 is an assembled perspective view of the V portion in FIG. 2
- FIG. 6 is a sectional view taken along the line VI in FIG. 2 (bottom view)
- FIG. 6 is a cross-sectional view taken along the line VII-VII in FIG.
- the lower flange 14c is provided with an elongated hole 32 extending in the direction in which the module cover 14 opens (in the direction of the room).
- a slit 34 is formed so as to connect one end of the long hole 32 to the end of the lower flange 14c.
- An opening 36 is formed in the bottom of the main container 12, and a rivet 38 is driven through the elongated hole 32 and the opening 36.
- the rivet 38 has no force.
- the line 40 is fitted externally.
- the outer diameter of the character 40 is larger than the width of the slit 34 described above.
- this passenger airbag device fold the airbag 18 and place it in the sub-container 20, after which the sub-bag 20 Can be inserted into the main container 12.
- the sub-con- troller is used to deliver the air nozzle 18. Even if the tena 20 is moved many times, the work is light work and the muscle fatigue is extremely small. As a result, work efficiency is improved.
- it is sufficient to lift the lightweight sub-container 18 and insert it into the main container 12. The work is very simple and requires little effort. (Automated operation by robots, etc., is also easy.)
- the air bag 18 can be replaced.
- the folding method is the same. -In the debugging device 10 configured as described above, when the inflation mechanism 16 is operated, the air knock 18 is deployed and the deployment pressure is applied. As shown in Fig. 8, the module cover 14 is pushed by the module cover 14 so that it can pass through the rivet 38 and the camera 14 force 5 slit 34. The lower half of the module cover 14 moves forward. And more air Due to the expansion force of the bag 18, the module force bar 14 bends along the groove 14 e and opens forward, and as shown in FIG. As shown in b), the air bag 18 is deployed indoors to protect the occupants.
- a long hole 32 is formed in the lower flange 14c, and the lower flange 14c and the main container 12 are formed.
- the module power bar 14 If pressed, or if the air pack 18 expands due to heat and presses the module cover 14, the module power bar 14 The lower half is shifted toward the room, so that local stress is prevented from being concentrated on the groove 14e. Also, for example, when the occupant presses the module cover 14, the lower half of the module cover 14 shifts in the direction of being pushed into the container 12. . As a result, local stress is prevented from being generated in the groove 14e.
