By the way, when the side window glass is covered from the vehicle interior by the curtain airbag, the curtain airbag can sufficiently resist the external force directed toward the vehicle interior or the exterior of the vehicle interior, particularly at the time of rollover (tension can be maintained). Would be desired). For this reason, the curtain airbag not only fixes the upper part of the curtain airbag to the vehicle body, but also fixes the portion corresponding to the rear end of the curtain airbag, that is, the portion along the rear edge of the side window glass, to the vehicle body. Would be desired.

On the other hand, the rear pillar is covered with a rear pillar trim to improve the appearance from the inside of the vehicle interior, but the rear pillar trim is a soft roof trim that covers the inner surface of the roof panel so that it is not easily damaged by luggage or the like. It is generally formed of a considerably harder member, more specifically, a hard synthetic resin. And when the side window glass in front of the rear pillar covered by the rear pillar trim is covered with the curtain airbag, the portion along the rear edge of the side window glass in the curtain airbag in the stored state is The rear pillar trim covers the vehicle so that it cannot be seen from inside the passenger compartment. Therefore, the curtain airbag in the housed state needs to be deployed in the vehicle interior while deforming at least the upper part of the predetermined end edge that is the outer edge in the vehicle width direction of the rear pillar trim. That is, since the predetermined edge portion of the rear pillar trim is positioned in the immediate vicinity of the side window glass, the curtain airbag in the stored state is deformed while deforming at least the upper portion of the predetermined edge portion forward. From the gap between the generated predetermined edge and the side window glass, the vehicle interior is developed.

By the way, the front pillar positioned at the front edge of the side window glass is generally covered from the vehicle interior side by a hard front pillar trim. The curtain airbag in the stowed state is located in the vehicle width direction of the front pillar trim in order to prevent interference (hook) with the front pillar trim (the upper edge portion) when attempting to inflate and deploy. It is desired to dispose the vehicle so as to pass inward in the vehicle width direction from the end. In this way, if the curtain airbag in the stowed state is extended rearward in a state where it is positioned considerably inward in the vehicle width direction in order to avoid interference with the front pillar trim, in the rear pillar trim portion, The curtain airbag in the stowed state is in a state of being positioned considerably inward in the vehicle width direction from the predetermined edge portion.

However, since the rear pillar trim is hard, it is difficult to be deformed. For this reason, when the curtain airbag in the stored state is positioned largely inward in the vehicle width direction, For deployment into the room, the rear pillar trim needs to be greatly and greatly deformed, making it difficult to ensure smooth inflation and deployment of the curtain airbag.

The present invention has been made in view of the circumstances as described above, and an object thereof is to provide a curtain airbag device that can smoothly inflate and deploy a curtain airbag performed while deforming the rear pillar trim. It is to provide a rear structure of a vehicle.

Therefore, the curtain airbag KB in the stored state is separated from the side window glass G3 in the vehicle width direction. The distance is set so that the rear edge portion upper end position and the upper edge rear end position of the side window glass are substantially the same.

As described above, the separation distance in the vehicle width direction with respect to the side window glass G3 of the curtain airbag KB in the housed state is the portion along the upper edge of the side window glass G3 (the front end position and the rear end position serving as the boundary portions are (Excluding the upper end position serving as the boundary portion) along the rear edge of the side window glass G3. The distance L1 or L2 corresponds to LB in the range, and the distance L5 corresponds to LC in the claims in the front pillar trim PT3 portion. The separation distances L1 and L2 in the portion along the rear edge of the side window glass G3 may be set to the same value (the position in the vehicle width direction in the portion along the rear edge of the side window glass G3 is the upper and lower portions). And set the same). The separation distances L1 to L5 have a relative relationship with the side window glass G3 (predetermined vehicle body outer surface). The larger the separation distances L1 to L5 are, the absolute position in the vehicle width direction is on the inner side. ing.

As is clear from FIGS. 12 and 11, the distance in the vehicle width direction from the side window glass G3 of the curtain airbag KB in the housed state is a portion corresponding to the assist grip 36 as the vehicle interior product in plan view. Further, it is located on the outer side in the vehicle width direction with respect to the portion located in front of the assist grip 36. Further, a portion of the curtain airbag KB in the stored state that is disposed behind the predetermined edge portion 26a is a boundary portion between the upper edge portion and the rear edge portion of the side window glass G3 (that is, in the rear pillar trim PT4). Twisted in the vicinity of the upper end portion of the predetermined edge portion 26a), and the development direction thereof has been changed. The portion along the upper edge portion of the side window glass G3 is directed substantially downward, and the rear edge of the side window glass G3. In the part along the part, as shown by the arrow γ in FIG.

Next, the operation of the above configuration will be described. When the curtain airbag KB is in the stowed state, when a predetermined condition is satisfied, such as when a side collision is detected or predicted, or when a vehicle rollover is detected or predicted, the inflator IR is detonated. The gas pressure generated by the initiation of the inflator IR is supplied to the curtain airbag KB in the housed state, and the curtain airbag KB is shaped as shown in FIG. .

The curtain airbag KB is inflated and deployed in the passenger compartment while displacing the outer edge of the roof trim RT in the vehicle width direction as indicated by an arrow α in FIG. 11 (expanded and deployed curtain air The bag KB is indicated by a dashed line). Since the roof trim RT is soft, it can be easily deformed downward. On the vehicle rear side, the curtain airbag KB is inflated and deployed while the upper part of the predetermined edge 26a of the rear pillar trim PT4 is displaced forward as shown by the arrow β in FIG. The curtain airbag KB is shown with a one-dot chain line). In FIG. 8, the curtain airbag KB is inflated and deployed into the passenger compartment through a gap formed between the side window glass G3 and the predetermined end edge 26a. The curtain airbag KB has a predetermined end edge. 26a has an inflating portion that is inflated in the vehicle width direction. Therefore, it is necessary to displace the predetermined end edge portion 26a (upper part thereof) forward inward while sufficiently displacing the predetermined end edge portion 26a. .

An opening 53 is formed in the front surface portion 26 at a lower position away from the predetermined edge portion 26a, and the strength near the opening 53 is weaker than other portions. As a result, when the curtain airbag KB presses the predetermined edge 26a forward, the front surface portion 26 is largely displaced as shown by a one-dot chain line in FIG. A large gap is formed in the vehicle width direction through which the vehicle passes. Then, the predetermined edge 26a may be largely displaced with a large area range (a range in which the distance to the upper part of the predetermined edge 26a is long) such as almost the entire front surface 26, and therefore the predetermined edge 26a. Compared with the case where the displacement is made largely only in the vicinity, an excessive force does not act on the predetermined edge portion 26a (particularly the upper portion) and the vicinity thereof, and the predetermined edge portion 26a and the vicinity thereof are partially The situation where it breaks is prevented.

In particular, in the present embodiment, in the portion near the boundary between the upper edge portion and the rear edge portion of the side window glass G3 (the upper end portion of the predetermined edge portion 26a), the curtain airbag KB 120 is 120 from the substantially horizontal direction in a side view. Is bent so as to be bent at an angle of less than or equal to the angle, and extends downward along the rear edge of the side window glass G3. When the curtain airbag KB is deployed, it is formed around the upper end of the predetermined edge 26a. On the other hand, the stress on the lower side and the stress on the front side work. In order to relieve the stress acting on the upper end, the curtain airbag KB is twisted at the portion corresponding to the upper end of the predetermined edge 26a (near the upper end) with respect to the rear pillar trim PT4. Although the development direction is set so as not to substantially intersect with the lower side and the front side, a certain amount of stress on the upper end is inevitable. On the other hand, since the opening 53 is spaced apart from the upper end where the stress acts in this way, the stress is prevented from acting on the opening 53 and the opening 53 is weakened. The vicinity is prevented from being damaged.

Here, as described above, the front surface portion 26 is set to be slightly inclined so as to be gradually positioned rearward as it goes outward in the vehicle width direction (setting of the rearward inclined portion 26d shown by a one-dot chain line in FIG. 12). . Thereby, especially when the portion near the boundary between the upper edge and the rear edge of the side window glass G3 of the curtain airbag KB in the stored state is to be inflated and deployed downward and forward, the rear Since the soft roof trim RT is positioned at the rear inclined portion 26d set to be inclined toward the rear, the stress due to the deploying curtain airbag KB acting in the vicinity of the boundary is released, and its deployability is improved. Become better. Further, by setting the upper portion of the predetermined edge portion 26a to be inclined downward toward the outer side in the vehicle width direction (substantially the same state as shown by the one-dot chain line in FIG. 12), Since the soft roof trim RT is also located at this inclination setting portion, the stress due to the curtain airbag KB that is deployed is released in the same manner as in the case where the rear inclination portion 26d is formed, and in particular, the upper portion of the predetermined edge portion 26a. The deployability of the curtain airbag KB from the front to the front is improved. In addition, you may make it set both the back inclination mentioned above and the downward inclination simultaneously.

In addition to the above, the curtain airbag KB stored in the rear of the predetermined edge 26a is set to be located on the outer side in the vehicle width direction as much as possible. Therefore, the predetermined edge 26a This is preferable in order to make the deformation as easy as possible and to improve the development. In particular, the stored curtain airbag KB behind the predetermined edge portion 26a is positioned on the outer side in the vehicle width direction as it goes downward, so that it sits on the third row seat SC that is the last row seat. This is also preferable for preventing interference between the occupant and the curtain airbag KB to be inflated and deployed.

The curtain airbag KB in the stored state is disposed at a portion corresponding to the assist grip 36 so as to be offset from the assist grip 36 toward the outer side in the vehicle width direction. Since the portion corresponding to the front pillar trim PT3 is positioned on the inner side in the vehicle width direction than the portion corresponding to the assist grip 36, the development is good without interfering with the assist grip 36 and the front pillar trim PT3. Will be done. Further, the curtain airbag KB in the stored state gradually (from the front pillar trim PT3 through the upper edge portion of the side window glass G3 and along the rear edge portion of the side window glass G3) Since, for example, the curtain airbag KB in the housed state is set to be separated at the portion along the upper edge of the side window glass G3. Compared to the case where the setting is kept at L5 and the position is suddenly offset to the outer side in the vehicle width direction in the vicinity of the rear edge position of the upper edge portion of the side window glass G3, the amount of sharp bending is not set. The deployability of the curtain airbag KB is improved.

Further, in the curtain airbag KB in the stored state, the portion along the rear edge of the side window glass G3 is oriented substantially outward in the vehicle width direction as indicated by an arrow γ in FIG. The curtain airbag KB that is inflated and deployed into the passenger compartment while deforming the edge portion 26a is deployed while being in contact with the side window glass G3, that is, the predetermined edge portion 26a and the side window glass G3. The gap as a passage for the curtain airbag KB to be formed between them is minimized, which means that the predetermined edge 26a does not need to be unnecessarily deformed, and the rear pillar trim This is preferable in preventing PT4 from being damaged near the predetermined edge portion 26a.

FIGS. 13 to 16 show a second embodiment of the present invention. The same components as those of the above embodiment are given the same reference numerals, and redundant description thereof is omitted (this is further described in the third embodiment below). The same applies to the following forms). In the present embodiment, the trim material positioned along the upper edge of the side window glass G3 is not the roof trim RT but the roof side trim RST formed of a hard synthetic resin. Shown (same quality as rear pillar trim PT3 and PT4). Such a roof side trim RST has a width in the vehicle width direction substantially the same as the width in the vehicle width direction of the pillar trim PT3, but is sufficiently larger than the width in the vehicle width direction of the front portion 26 of the rear pillar trim PT4. It is supposed to be small.

The roof side trim RST has a plurality of locking projections 61 on the upper surface thereof, and is fixed to the lower surface of the roof side rail 32 by using the locking projections 61. (See FIG. 14). The curtain airbag KB in the stowed state is disposed so as to be positioned slightly inward in the vehicle width direction from the roof side trim RST in the portion along the upper edge of the side window glass G3 (see FIG. 14 to 16). That is, when inflated and deployed, the curtain airbag KB in the stowed state is deployed in the vehicle compartment while deforming the roof trim RT downward from between the roof side trim RST and the roof trim RT. It is like that. The roof side trim RST is displaced downward even when the latching projection 61 is firmly locked to the roof side rail 3 and receives pressure during expansion and deployment of the curtain airbag KB. However, the locking position of the locking projection 61 with respect to the roof side rail 32 may be changed slightly downward when subjected to pressure during expansion and deployment. -The side trim RST is only displaced downward by a predetermined amount so that it does not fall off the roof side rail 32).

Note that the assist grip 36 is set at a position sufficiently closer to the inner side in the vehicle width direction than in the case of the above-described embodiment, and is positioned closer to the inner side in the vehicle width direction than the inflator IR. The curtain airbag KB in the housed state is set so that the position in the vehicle width direction is the same between the portion along the upper edge of the side window glass G3 and the front pillar PT3 portion. Also in this embodiment, the curtain airbag KB can be smoothly inflated and deployed.

17 to 19 show a third embodiment of the present invention. In the present embodiment, of the front surface portion 26 of the rear pillar trim PT4, a predetermined portion including the predetermined edge portion 26a, more specifically, a portion of the front surface portion 26 on the outer side in the vehicle width direction and substantially in the vertical direction. The upper part from the intermediate position is constituted by a cover member 27 formed separately. The cover member 27 is integrated with the other portion (main body portion) of the rear pillar trim PT4 via the hinge 28 so that the front surface portion 26 is flush with the surface. The hinge 28 is formed in a loop shape (substantially semicircular arc shape) with, for example, a soft synthetic resin, and is set such that the cover member 27 can be easily swung forward about the hinge 28. And the cover member 27 is latched by the rear pillar P4 using the latching protrusion part 27b formed in the front-end | tip part of the support stay 27a projected from the back surface. When the curtain airbag KB is inflated and deployed, the locking action on the rear pillar P4 of the locking special note portion 27b is easily released, and the cover member 27 is centered on the hinge 28 as shown by the one-dot chain line in FIG. Thus, the curtain airbag KB can be easily swung forward and the deployability of the curtain airbag KB is extremely good.

FIG. 20 shows a modification of FIG. 19 in which a portion corresponding to the cover member 27 is formed integrally with the front surface portion 26 of the rear pillar trim PT4. That is, a groove 26b that functions as a hinge 28 from the back side of the front surface portion 26 is formed at a boundary line portion between the cover portion 27 'corresponding to the cover member 27 and other portions. A state when the curtain airbag KB is in the stored state is shown by a solid line in FIG. 20, and a state when the curtain airbag KB is inflated and deployed is shown by a dashed line in FIG.

FIG. 21 shows a fourth embodiment of the present invention. When the rear pillar trim PT4 is subjected to a predetermined or more forward pressing force, the rear pillar trim PT4 is almost entirely against the rear pillar P4. It can be displaced forward. In other words, the locking projection 29a is formed at the tip of the support stay 29 protruding from the back side of the front surface portion 26, and the locking projection 29a is locked to the rear pillar P4. Then, when a forward pressing force greater than or equal to a predetermined value acts on the front surface portion 26, the locking action on the rear pillar P4 of the locking projection 29a is easily released, and as shown in FIG. The pillar trim PT4 is easily displaced forward almost entirely, and the deployability of the curtain airbag KB is improved.

FIG. 23 shows a fifth embodiment of the present invention. In the present embodiment, among the front surface portion 26 of the rear pillar trim PT4, in particular, the vicinity of the predetermined edge portion 26a is bent so as to protrude rearward so as to be positioned largely forward as it goes outward in the vehicle width direction. It is a thing. According to this embodiment, when the curtain airbag KB is inflated and deployed, the predetermined edge portion 26a side is more easily displaced inward in the vehicle width direction, and the curtain airbag KB is greatly curved. As a result, the area that receives the pressing force is increased (correspondingly, breakage in the vicinity of the predetermined edge portion 26a can be more sufficiently prevented). Further, when receiving a forward pressing force from the curtain airbag KB, the predetermined edge portion 26a is quickly displaced in a direction away from the side window glass G3 without any movement approaching the side window glass G3. Will be.

FIG. 24 shows a sixth embodiment of the present invention. In the present embodiment, the outer end portion in the vehicle width direction of the roof trim RT is formed so as to be curved downward toward the outer side in the vehicle width direction. From the curtain airbag KB, as in the case of FIG. When the pressure at the time of expansion and deployment is received, the downward displacement of the roof trim RT is made easier.

Although the embodiment has been described above, the present invention is not limited to the embodiment, and can be appropriately changed within the scope described in the scope of claims. For example, the invention includes the following cases. . The curtain airbag KB in the stored state is gradually positioned on the outer side in the vehicle width direction from the front end portion toward the rear end portion along the upper edge portion of the side window glass G3 (side window glass The inclination may be set so that the distance from G3 is small. Instead of the assist grip 36 for the vehicle interior product shown in FIG. 12 or the like, for example, an air conditioning duct (the opening in the vehicle interior is formed in the roof trim RT) or the like may be used. The opening 53 may be, for example, for a microphone, for air conditioning (for blowing air-conditioned air), for ventilation for air purification (suction port or outlet), etc. It may be used for decorative purposes, and the formation position can be appropriately selected such as the upper portion of the side surface portion 25 in the rear pillar trim PT4. The vehicle may be a vehicle that does not have a back door. The side window glass to which the present invention is applied may be for the first row side window glass G1 (especially when there is no rear seat after the second row) or the second row side window glass G2. The present invention is applicable as long as the curtain airbag in the housed state is disposed along the rear edge of the target side window glass (particularly when there is no third row sheet). The curtain airbag may be a plurality of curtain airbags divided in the front-rear direction. The rear pillar trim PT4 is not limited to the case where the horizontal cross-sectional shape is L-shaped, and can be appropriately changed to an arc shape, for example. To ensure that the inflated and deployed curtain airbag KB can be fully countered by the external force in the vehicle width direction, the lower end of the curtain airbag KB is set to be inflated more widely in the vehicle width direction than the other parts over the entire length. Also good. Of course, the object of the present invention is not limited to what is explicitly stated, but also implicitly includes providing what is substantially preferred or expressed as an advantage.
