Description

  The present invention relates to an air bag including an air bag main body which is stored in a folded state from a roof side portion of a vehicle body to a vertical direction of a vehicle room along a vertical direction of the vehicle room and straddling a pillar portion covered by a covering member.

  2. Description of the Related Art Conventionally, an air bag apparatus provided with an air bag into which gas is introduced to inflate and deploy is an air bag which is long back and forth along a predetermined surface including a pillar portion on a side of a car compartment and a window of a door. A so-called curtain airbag device is known which deploys. The air bag of such an air bag device is usually folded in an elongated shape and disposed along the roof side portion of the upper edge portion of the window portion. Then, when an impact such as a side collision or rollover is received, the inflator supplies gas, and the air bag inflates and deploys downward along the side window glass etc. to restrain the occupant. Protect the head etc.

  In recent years, in addition to a head-on collision, the airbag is required to have a restraint performance of an occupant during an oblique collision in which a part of the vehicle collides obliquely with an obstacle (oblique collision). Therefore, the required protection area by the air bag extends to the front, and the air bag is extended, for example, to the position of the front pillar (A pillar). In this case, it is desirable that the airbag not be caught on the front pillar trim at the time of deployment since the airbag straddles the split position of the roof side trim and the front pillar trim as the covering member in the stored state.

  In this respect, for example, there is known a configuration in which a protection area on the front end side of the airbag is stored in a folded state so as to be folded back (for example, see Patent Document 1). However, in this configuration, the storage may not be easy when the protection area of the airbag is expanded widely to the front.

  Then, when manufacturing the airbag 10, the vehicle-side base fabric 35 and the vehicle-side base fabric 36 are joined by sewing or the like by the outer edge joint portion 45 and the inner joint portion 46, respectively, to provide air having the inflating portion 38. The bag body 31 is formed. Furthermore, the reinforcing cloth 33 overlapped with the in-vehicle base cloth 36 of the air bag main body 31 is joined by sewing or the like by the reinforcing cloth joint 55, so that the air bag main body 31 and the reinforcing cloth 33 are integrated. The air bag 10 provided for the above is completed. In this state, the gas injection side of the inflator is inserted into the insertion opening of the gas introduction portion 41, and the inflator is integrally fixed as exposed from the air bag 10 to the outside.

  Furthermore, the airbag body 31 is rolled up together with the reinforcing cloth 33 in a roll shape and the like, and the airbag 10 is folded into a predetermined elongated shape, and the pressure at the time of deployment of the airbag 10 using a holding member 57 such as tape. Hold the folded shape so that it can be unbonded or broken. At this time, the reinforcing cloth 33 is wound up so as to be exposed to the side of the casing 14 with respect to the air bag main body 31. Thus, the air bag 10 is folded into a long and thin shape, and the folded shape is maintained, whereby an air bag device to be a curtain air bag module is configured.

  Then, the airbag apparatus equipped with the airbag 10 folded as described above is brought into the compartment 14 and the head lining 26 and the front pillar trim 27, the center pillar trim, the rear pillar trim, and other interior materials are attached to the vehicle body. Perform installation work. The mounting operation is performed by mounting and fixing the plurality of mounting portions 42 and the tether portion 32 of the air bag main body portion 31 to the vehicle body with a fixing tool such as a bolt (not shown). In addition, the inflator is fixed, for example, at a position corresponding to the upper side of the rear pillar. Furthermore, the harness derived from the inflator is connected to a control device provided on the vehicle body. Next, the head lining 26 is attached so as to cover the ceiling panel and the vehicle body panel 25 of the vehicle body, and the front pillar trim 27, the center pillar trim and the rear pillar trim are attached to the front pillar 21, center pillar and rear pillar respectively to cover the airbag device Installation work of the device to the car body is completed. In this mounting state, the airbag device is separated from the interior of the compartment 14 by the head lining 26 and the front pillar trim 27, the center pillar trim, and the rear pillar trim, and the inflator inserted into the gas introduction portion 41 is folded in a roll The airbag 10 and the front pillar trim 27, the center pillar trim, and the rear pillar trim are held at positions extending from the roof side portion 15 to the front pillar 21. That is, the air bag main body 31 and the reinforcing cloth 33 are disposed respectively from the roof side 15 to the front pillar 21 and are covered by the head lining 26 and the front pillar 21 (FIG. 2). More specifically, the airbag body 31 is disposed mainly at the roof side portion 15 and covered by the head lining 26, and the front end side is disposed at the front pillar 21 and covered by the front pillar trim 27. The reinforcing cloth 33 is mainly disposed on the front pillar 21 and covered by the front pillar trim 27, and the rear end side is disposed on the roof side portion 15 and covered by the head lining 26.

  Then, in the case of a side collision or rollover including a frontal collision of a vehicle, a minute lap collision or an oblique collision (collision from an oblique front), the control device activates the inflator and the gas injected from the inflator is introduced. The air bag body 31 is introduced into the air bag main body 31 of the air bag 10 from the portion 41, and the air bag main body 31 inflates and deploys in a planar manner along a predetermined surface of the side of the compartment 14 to protect the occupant .

  More specifically, in the air bag 10, when the gas is supplied by the gas introducing portion 41, the gas introduced from the gas introducing portion 41 is supplied to the front portion of the expanding portion 38 along the first bonding portion 51. It is supplied to the rear of the expansion portion 38 from the position below the tip of the first joint 51. For this reason, the air bag main body portion 31 expands so as to inflate the inflating portion 38 and deforms the lower end portion of the head lining 26 so as to push away the indoor side of the compartment 14.

  At this time, for example, a portion on the front end side extending to the front pillar 21 of the airbag main body 31 is shrunk backward (shrunk) as shown in FIGS. 3A to 3D. Expand (arrow A). For this reason, the front end of the airbag body 31 moves in the direction in which the front end side of the airbag body 31 rubs against the front pillar trim 27 covering the front pillar 21. In the present embodiment, the reinforcing cloth 33 is located in this portion. The reinforcing cloth 33 prevents the air bag body 31 from being directly rubbed against the front pillar trim 27, and the reinforcing cloth 33 absorbs the friction with the front pillar trim 27 so that the air bag body 31 and the front pillar trim 27 Of the front pillar trim 27 along with the reinforcing cloth 33 while pushing the upper end of the front pillar trim 27 to the inside of the compartment 14 without being affected by the friction of the front pillar trim 27 and the center pillar trim , Projects from the upper end of the rear pillar trim into the compartment 14, and rolls down quickly along a predetermined surface And expand smoothly.

  As described above, according to the present embodiment, the airbag main body 31 housed in the folded state is straddled over the front pillar 21 covered with the front pillar trim 27 from the roof side portion 15 of the vehicle body to the compartment 14 side. The reinforcing cloth 33 covering the side of the compartment 14 in the unfolded state of the airbag main body 31 is disposed so as to be located straddling the roof side portion 15 and the front pillar 21 in the stored state of the airbag main body 31. By doing so, it is possible to prevent the reinforcing cloth 33 from rubbing or catching the air bag body 31 with the front pillar trim 27 during deployment, and the air bag body 31 can be developed smoothly.

  In particular, the air bag body 31 is a front body whose roof 14 side is covered by the front pillar trim 27 from the roof side portion 15 which is covered by the head lining 26 which is separate from the front pillar trim 27 and which is adjacent to the front pillar trim 27. Since the airbag 21 is accommodated over the pillars 21, the airbag main body 31 is deployed with the head lining 26 or the front pillar trim when the airbag main body 31 is deployed by the reinforcing cloth 33 disposed so as to be located from the roof side 15 to the front pillar 21 in this stored state. It is possible to prevent the air bag 27 from being rubbed or caught, and the air bag body 31 can be deployed more smoothly.

  Further, by joining the reinforcing cloth 33 at a position ranging from the upper portion to the lower portion of the front edge portion of the airbag main body portion 31, the entire front edge portion of the airbag main body portion 31 is reliably covered with the reinforcing cloth 33. The reinforcing cloth 33 can reliably prevent the portion 31 from being rubbed or hooked on the front pillar trim 27 or the head lining 26 at the time of deployment.

  Then, the airbag main body portion 31 is smoothly deployed, so that the input to the front pillar trim 27 is reduced, and the damage and the detachment of the front pillar trim 27 can be prevented.

  Furthermore, by stabilizing the deployment behavior of the air bag body 31, the initial restraint of the occupant can be accelerated, and the performance can be stabilized. Moreover, since the airbag body 31 does not contact the front pillar trim 27 directly, even if the front pillar trim 27 is fitted with an edge or the like, the airbag body 31 may be damaged by the contact with the edge or the like. It can prevent.

  Particularly in recent years, from the viewpoint of protection against oblique collision (oblique collision) and the like, since the required protection area forward of the occupant by the airbag 10 has become larger, the front pillar with the front end portion of the airbag main body 31 stored 21 (front pillar trim 27) side is greatly extended, and the deployment speed is delayed due to the influence of friction due to direct contact with the front pillar trim 27, the occupant restraint performance is reduced, or the front pillar trim 27 is There is a concern that the airbag body 31 may be caught or the front pillar trim 27 may be damaged or come off, but in the present embodiment, even if the front end of the airbag body 31 is extended forward, Such problems are less likely to occur.

  In the above-described embodiment, the reinforcing cloth 33 is disposed so as to extend from the roof side 15 to the front pillar 21 in the stored state. However, the airbag main body 31 is disposed from the roof side 15 to the center pillar. In the case of a car type that is stored so as to straddle the rear pillar, even if the reinforcing cloth 33 is arranged to be positioned so as to straddle the center side pillar or the rear pillar from the roof side portion 15 in the stored state, similar effects can be achieved. it can.

  Further, the base cloth (car-side base cloth 36) of the air bag main body 31 can exhibit the same function and effect regardless of whether it is coated with a synthetic resin such as a silicone elastomer.

  The present invention is applicable to, for example, an airbag and an airbag apparatus that protects an occupant by being installed and deployed along a window of a side portion of a car.
