Description

  The present invention relates to a rear structure of a vehicle provided with a curtain airbag device.

2. Description of the Related Art In vehicles, particularly automobiles, it is common to equip an airbag device for protecting an occupant during a collision or rollover. Some of these airbags are inflated and deployed in the passenger compartment so as to cover the side window glass as called curtain airbags. Such a curtain airbag may be long in the front-rear direction so as to cover a plurality of side window glasses spaced in the front-rear direction. Patent Document 1 discloses a curtain airbag that is extremely long in the front-rear direction so that it can cover all three side window glasses spaced in the front-rear direction. In the one described in Patent Document 1, the curtain airbag in the housed state is fixed to the vehicle body along the upper edge portion of the side window glass, and is also fixed to the rearmost pillar.
JP 2004-189099 A

  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. Will 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.

  Recently, a roof side trim that extends in the front-rear direction is disposed along the upper edge of the side window glass positioned just before the rear pillar trim in order to improve the appearance from the passenger compartment. The roof side trim is also harder than the roof trim, as is the rear pillar trim. In this way, when a rigid roof side trim that extends in the front-rear direction along the upper edge of the side window glass is disposed, the curtain airbag can be secured without being disturbed by the roof side trim. The problem is whether to smoothly deploy the vehicle interior.

  The present invention has been made in view of the circumstances as described above, and its object is to provide a curtain airbag device that can satisfactorily deploy a curtain airbag even when a roof side trim is provided. It is to provide a rear structure of a vehicle.

In order to achieve the above object, the following first solution is adopted in the present invention. That is, as described in claim 1 in the claims,
Side window glass is arranged in front of the rear pillar located at the rear of the vehicle,
A curtain airbag device having a curtain airbag fixed to the vehicle body in a stored state in the vicinity of the side window glass, and an inflator for supplying gas pressure to the curtain airbag;
The curtain airbag is deployed on the vehicle interior side so as to cover the side window glass along the side window glass when the curtain airbag is inflated by receiving gas pressure from the inflator. In the rear structure of the vehicle with the device,
The curtain airbag in the storage state is fixed to the vehicle body along the upper edge and the rear edge of the side window glass,
The rear pillar is covered from the inside of the vehicle by a rear pillar trim that is harder than a soft roof trim that covers the roof panel from the vehicle interior side,
Between the side window glass and the roof trim, a roof side trim extending in the front-rear direction along the upper edge of the side window glass is disposed,
When the curtain airbag in the stored state is inflated, the curtain airbag is set so as to be deployed in a vehicle compartment through a boundary portion between the roof side trim and the roof trim.
It is like that. According to the above solution, the curtain airbag is easily moved downward from the boundary portion between the roof side trim and the roof trim at the portion along the roof side trim, that is, the soft roof trim. It will be easily deployed in the passenger compartment while being deformed, and good deployability of the curtain airbag will be ensured.

In order to achieve the above object, the following second solution is adopted in the present invention. That is, as described in claim 2 in the scope of claims,
Side window glass is arranged in front of the rear pillar located at the rear of the vehicle,
A curtain airbag device having a curtain airbag fixed to the vehicle body in a stored state in the vicinity of the side window glass, and an inflator for supplying gas pressure to the curtain airbag;
The curtain airbag is deployed on the vehicle interior side so as to cover the side window glass along the side window glass when the curtain airbag is inflated by receiving gas pressure from the inflator. In the rear structure of the vehicle with the device,
The curtain airbag in the storage state is fixed to the vehicle body along the upper edge and the rear edge of the side window glass,
The rear pillar is covered from the inside of the vehicle by a rear pillar trim that is harder than a soft roof trim that covers the roof panel from the vehicle interior side,
Between the side window glass and the roof trim, a roof side trim extending in the front-rear direction along the upper edge of the side window glass is disposed,
When the curtain airbag is inflated when the rear end portion of the roof side trim is adjacent to the upper end portion of the front portion of the rear pillar trim, and the curtain airbag in the stored state is inflated, -It is set to be deployed in the vehicle interior through a boundary portion between the rear end portion of the side trim and the upper end portion of the front portion of the rear pillar trim.
It is like that. According to the above-described solution, the curtain airbag is easily deployed in the vehicle interior through the boundary portion between the rear end portion of the roof side trim and the front portion of the rear pillar trim at the rear end portion of the roof side trim. As a result, good deployability of the curtain airbag is ensured.

A preferable mode based on the solution method of the guide 1 or the second solution method is as described in claim 3 and the following. That is,
When the curtain airbag in the retracted state is inflated, the curtain airbag is deployed in the vehicle compartment through the rear pillar trim and the side window glass while deforming the front portion of the rear pillar trim toward the front. (Corresponding to claim 3). In this case, the curtain airbag is deployed from the outer side in the vehicle width direction as much as possible, and the curtain airbag that is inflated and deployed to the occupant seated on the seat disposed near the side window glass is provided. This is preferable in terms of preventing interference.

  An upper end portion of the front portion of the rear pillar trim is inclined so as to be located rearward as it goes outward in the vehicle width direction in a plan view, or is positioned downward as it goes outward in the vehicle width direction in a front view. It is so inclined (corresponding to claim 4). In this case, by setting the inclination, the length of the portion where the curtain airbag in the stored state is covered by the rear pillar trim is shortened, and the deployability of the curtain airbag is improved accordingly. In addition, the downward inclination setting greatly reduces the possibility that the curtain airbag to be inflated and deployed will be caught on the upper edge of the rear pillar trim, further improving the deployability and preventing damage to the rear pillar trim. This is also preferable.

  A cover portion that is set so that a specific portion including a predetermined edge portion, which is an end portion on the outer side in the vehicle width direction, of the front portion of the rear pillar trim is easily displaced forward relative to the other portions. It is formed (corresponding to claim 5). In this case, since the cover portion can be easily deformed forward, it is possible to sufficiently satisfy both of ensuring good deployability of the curtain airbag and preventing damage to the rear pillar trim.

  The upper end portion of the cover portion is set so as to be positioned closer to the vehicle interior side than the rear end portion of the roof side trim (corresponding to claim 6). In this case, it is possible to reliably prevent the roof side trim from interfering with the forward deformation of the cover portion.

  The attachment position of the roof side trim to the vehicle body is set so as to be only the front position rather than the substantially middle position in the front-rear direction (corresponding to claim 7). In this case, it is preferable to facilitate the downward deformation at the rear end portion of the roof side trim and the vicinity thereof as much as possible, and to ensure the good deployability of the curtain airbag more reliably.

A front pillar is disposed along the front edge of the side window glass,
The front pillar is covered from the vehicle interior side by a front pillar trim that is harder than the roof trim,
When the curtain airbag in the stowed state is inflated, the curtain airbag is deployed in a vehicle interior through a boundary portion between the front pillar trim and the roof trim.
This is done (corresponding to claim 8). In this case, the curtain airbag can be satisfactorily deployed in the passenger compartment through the boundary portion between the front pillar trim and the roof trim, that is, the soft roof trim is easily deformed downward. In addition, from the front pillar trim to the roof side trim, all of the curtain airbags are deformed while the soft roof trim is deformed downward at a position far from the side window glass inward in the vehicle width direction. Since the interior of the vehicle is deployed, there is no need to significantly offset the curtain airbag that is stored in the front pillar trim part outwardly in the vehicle width direction or to twist it to change the deployment direction. The curtain airbag can be smoothly deployed in the vehicle interior without being caught by the front pillar trim.

  The curtain airbag is set so as to have an inflating portion extending in the vehicle width direction between the rear pillar trim and the side window glass when inflated and deployed (corresponding to claim 9). In this case, even when the seat is positioned on the side of the side window glass, it is preferable in protecting a passenger seated on the seat over a wide range.

  The roof side trim is set so that the width in the vehicle width direction is sufficiently smaller than that of the rear pillar trim, and at least the rear end portion thereof is formed into a thin plate shape and can be easily deformed downward. (Corresponding to claim 10). In this case, it is preferable for better deployment of the curtain airbag in the vehicle interior without being obstructed by the roof side trim.

  According to the present invention, even when a hard roof side trim is provided along the upper edge of the side window glass, it is possible to ensure a good deployability of the curtain airbag.

  1 and 2, the vehicle V includes a front seat SA, a second row seat SB disposed behind the front seat SA, and a specific seat disposed behind the second seat SB. And the third row sheet SC. The side door for the front seat SA is indicated by the symbol SD1, and the side door for the second row seat SB is indicated by the symbol SD2. The vehicle V has, as pillars, sequentially from front to rear, an A pillar P1, a B pillar P2, a C pillar P3 as a front pillar, and a D pillar P4 as a rear pillar. A space between the left and right D pillars P4 is a rear opening 10 that is opened and closed by a back door BD. Through the rear opening 10, the loading and unloading of the luggage with respect to the luggage compartment 11 behind the third row seat SC is performed.

  The side door SD1 opens and closes the entrance / exit opening 12 between the A pillar P1 and the B pillar P2, and includes a side window glass G1 that is opened and closed in the vertical direction. The side door SD2 opens and closes the entrance / exit 13 between the B pillar P2 and the C pillar P3, and includes a side window glass G2 that is opened and closed in the vertical direction. A side window glass G3 is arranged between the C pillar P3 and the D pillar P4. In the embodiment, the side window glass G3 is fixed (stolen) and cannot be opened and closed. However, it may be openable. The rear side opening covered with the side window glass G3 is indicated by reference numeral 14.

  The three side window glasses G1 to G3 are, for example, almost entirely covered from the vehicle interior by a curtain airbag KB that is activated at the time of a side collision or at the time of prediction, at the time of rollover or at the time of prediction. It has become. The curtain airbag KB is fixed to the vehicle body along the edges of the three side window glasses G1 to G3 in the stored state. That is, the curtain airbag KB in the storage state has a front end portion fixed to the A pillar P1, a rear end portion fixed to the D pillar P4, and an intermediate portion between the front end portion and the rear end portion is a side window. It is being fixed to the vehicle body on the line | wire which tied the upper edge part vicinity of glass G1-G3 in the front-back direction. The curtain airbag can be fixed to the vehicle body as appropriate, for example, continuously or at predetermined intervals.

  When the curtain airbag KB is inflated and deployed, the curtain airbag KB is deployed in the vehicle compartment along the side window glasses G1 to G3 with hatching in FIG. 2, and all the side window glasses G1 to G3 are installed in the vehicle interior. It is made to cover from the inside. And, when inflated and deployed, the curtain airbag KB has a lower end so that it is positioned slightly below the belt line (so that it is positioned slightly below the lower edge of each side window glass G1 to G3). Is set. The portion of the curtain airbag KB that is not hatched in FIG. 2 is a non-inflatable portion 1 that is not partially supplied with gas pressure, and is in a thin state that does not substantially inflate in the vehicle width direction. Yes. In addition, the formation position of such a non-expandable part 1 is set in the position considerably distant from the passenger | crew's head position seated on each sheet | seat SA-SC. Providing such a non-inflatable portion 1 is preferable for early expansion and deployment of the curtain airbag KB, but it can also be set so as not to provide the non-inflatable portion 1. Further, the front end of the curtain airbag KB can be fixed to the vehicle body around the middle portion of the front end portion of the A pillar P1, and in this case, the front end (lower end portion) of the curtain airbag KB and the vicinity of the front end of the A pillar P1 Are preferably connected by a tether (string member).

  FIGS. 3A to 3D show an example in which the curtain airbag KB is folded into a stored state. That is, the curtain airbag KB (see FIG. 3A) deployed in a thin state where no gas pressure is supplied is folded in a bellows shape from the lower end position direction (see FIG. 3B), Eventually, it becomes a single rod-like body (see FIG. 3C, the outer shape of the cross section is, for example, substantially rectangular). In addition, folding may be made to overlap sequentially from the lower end side in the front side direction and the back side alternately, or may be made to overlap only in one direction on the front side or the back side, and further on the front side or the back side. A method of rounding from one direction may be used, and a folding method can be appropriately selected. Then, a predetermined portion of the rear end portion of the curtain airbag KB having a rod shape is twisted, and the predetermined portion is bent downward from the linear state in FIG. The curvature of the front end portion corresponds to the inclination of the A pillar P1, and is directed relatively gently downward. Further, the curvature of the rear end portion of the curtain airbag KB corresponds to the inclination of the D pillar P4, and the D pillar P4 is substantially straightly curved in the vertical direction, so that it curves considerably more rapidly than the front end portion. And it is going to go down. When the curtain airbag KB in the storage state is fixed to the vehicle body, the rear end portion extends downward while curving from the rear edge portion of the side window glass G3 to the upper portion of the rear edge portion, The lower end position is positioned near the lower edge of the side window glass G3 or at a position that does not reach the lower edge (in the embodiment, a substantially intermediate position in the vertical direction of the rear edge of the side window glass G3). (See FIG. 1).

  In FIGS. 1 and 2, IR is an inflator fixed to the vehicle body, and supplies inflated and deployed gas pressure to the curtain airbag KB in the housed state. In the embodiment, the gas pressure generated when the inflator IR is detonated is supplied to the curtain airbag KB in the housed state via the two supply systems 2 and 3 in the front and rear. The front supply system path 2 supplies gas pressure from a substantially intermediate position in the front-rear direction of the curtain airbag KB in the housed state. The rear supply path 3 supplies gas pressure to the vicinity of the rear end of the curtain airbag KB in the stored state. It should be noted that the number of supply paths 2 and 3 and the gas pressure supply position to the curtain airbag KB in the housed state can be changed as appropriate. The curtain airbag device KBS is configured by the curtain airbag KB, the inflator IR, the supply paths 2, 3 and the like.

  Each of the pillars P1 to P4 described above is covered with a pillar trim from the vehicle interior side, and as shown in FIGS. 4 to 7, the pillar trim of the C pillar P3, that is, the front pillar trim is indicated by reference numeral PT3, and the D pillar P4 The pillar trim or rear pillar trim is designated PT4. Further, the passenger compartment side of the roof panel RP (see particularly FIG. 11) is covered with a roof trim RT (the roof trim is not shown in FIGS. 1 and 2). The roof trim RT is formed of a soft material such as an elastic body, for example, foamed urethane or the like whose surface is covered with a non-woven fabric, etc., and can be deformed relatively easily with an external force that is pressed by a finger. Has been. Each pillar trim such as the front pillar trim PT3 and the rear pillar trim PT4 can be made of a hard synthetic resin, for example, polypropylene. In particular, the rear pillar trim PT4 is not easily damaged at a low temperature (for example, −20 ° C.) or less. It is made of (polypropylene made of thermo-plastic olefin) and is not easily deformed by an external force that is pressed by fingers. As described above, the rear pillar trim PT4 is made harder (sufficiently hard) than the roof trim RT, and is not easily damaged even when a load or the like comes into contact therewith.

  FIG. 20 shows a preferable setting example in the front pillar trim PT3 portion. That is, the front pillar (C pillar) P3 is formed in a closed cross section by the inner panel P3 • 1 and the outer panel P3 • 2, as is known, and the front portion that covers the front pillar P3 from the vehicle interior side. The upper end of the pillar trim PT3 is slightly separated from the inner surface (inner panel P3.1) of the front pillar P3 in the vehicle width direction, and there is a gap in the vehicle width direction between the front pillar P3 and the front pillar trim PT3. A gap 30 is formed. The upper opening of the gap 30 is covered with a roof trim RT. The mounting bracket 42 holding the curtain airbag KB in the housed state in the vicinity of the front pillar trim PT3 has an extension 42a extending downward. The extending portion 42a is inclined so as to be gradually positioned on the inner side in the vehicle width direction as it goes downward, and the directing direction thereof is directed to the inner end position in the vehicle width direction of the front pillar trim PT3. (It may be set so as to be slightly inward in the vehicle width direction from the inner end position). By providing such an extension 42a, the inflated and deployed curtain airbag KB can enter the gap 30 without any interference with the front pillar trim PT3 by the guide action of the extension 42a. It is surely deployed in the passenger compartment. In addition, as shown by a dashed-dotted line in FIG. 20, the curtain airbag KB is deployed by being disposed further inward in the vehicle width direction than the upper end portion (the inner edge portion in the vehicle width direction) of the TPPT3. Interference between the curtain airbag KB to be tried and the upper end portion of the front pillar trim PT3 can be reliably prevented.

  As shown in FIG. 8 in particular, the rear pillar P4 is formed in a closed cross-sectional shape by an inner panel 21 and an outer panel 22, and a joining flange portion 23 that extends short forward is formed at the front end portion thereof. The rear edge portion of the side window glass G3 is fixed to the outer surface of the joint flange portion 23 via an adhesive 24 (see also FIG. 9). As shown in FIG. 8, the rear pillar trim PT4 covering the rear pillar P4 has a substantially L-shaped cross section in the horizontal direction, and a side portion 25 extending widely in the front-rear direction, A front portion extending from the front end in the vehicle width direction and extending widely in the vehicle width direction. And the vehicle width direction outer side edge part, ie, the predetermined edge part 26a, of the front surface part 26 is located in the vicinity of the rear edge part of the side window glass G3 and extends to the vicinity of the joint flange part 23 (FIG. 9). reference).

  As shown in FIG. 11, the outer end portion of the roof panel RP in the vehicle width direction is a roof side rail 32 as a strength member having a closed cross section extending in the front-rear direction by an inner panel (reinforcement) 31. ing. The roof side rail 32 has a joining flange portion 33 that extends shortly downward at the lower end thereof, and the upper edge portion of the side window glass G3 is an adhesive 34 (see FIG. 9). As shown in FIGS. 4 and 13, the roof trim RT has an outer edge in the vehicle width direction that slightly protrudes outward in the vehicle width direction between the pillar trim PT3 and the rear pillar trim PT4. The glass G3 is prevented from reaching. A roof side trim RST extending in the front-rear direction along the upper edge is disposed in the immediate vicinity of the upper edge of the side window glass G3. That is, the roof side trim RST is positioned on the outer side in the vehicle width direction of the roof trim RT. This roof side trim RST is a roof trim for reasons such as the small opening of the back door BD or the like when the roof trim RT is moved from the outside of the vehicle through the opening of the vehicle to the inside of the vehicle compartment and attached to the roof. This is set when the RT cannot be formed large, and the part that cannot pass through the opening is made the roof side trim RST as a separate body from the roof trim RT, thereby improving the attachment of the roof trim RT. Yes. Of course, in order to improve the appearance, a roof side trim RST may be attached.

  The roof side trim RST is made of a synthetic resin that is harder than the roof trim RT, specifically, like the material constituting the rear pillar trim PT4, like the rear pillar trim PT4. The roof side trim RST has a thin plate shape as a whole, and is sufficiently smaller in width in the vehicle width direction than the front surface portion 26 of the rear pillar trim PT4. The roof side trim RST is formed on the roof side rail 32 (the inner panel 31 forming the roof side rail 32) by using a locking projection 61 that is set at a position further forward than a substantially intermediate position in the front-rear direction. It is fixed. The rear end portion of the roof side trim RST is positioned in the immediate vicinity of the upper end portion (front end portion) of the rear pillar trim PT4, and is adjacent to both the members RST and PT4 so that there is almost no gap. Alternatively, they may be arranged adjacent to each other so as to have a slight gap. Similarly, the front end portion of the roof side trim RST is located in the vicinity of the rear end portion of the front pillar trim PT3 and is adjacent to the both members RST and PT3 so that there is almost no gap between them. Alternatively, they may be arranged adjacent to each other so as to have a slight gap. In addition, when the said clearance gap is formed, it is preferable to fill a clearance gap with a small molding material or a filler.

  As shown in FIGS. 8 and 11, the curtain airbag KB in the housed state is fixed to the vehicle body via the mounting brackets 41 and 42 and the like. The mounting bracket 41 shown in FIG. 8 is for mounting to the rear pillar P4, and the mounting bracket 42 shown in FIG. 11 is for fixing to the roof side rail 32. FIG. 13 shows an example of the arrangement of the curtain airbag KB in the storage state in the portion extending from the upper edge to the rear edge of the side window glass G3. FIG. 13 clearly shows the arrangement of the curtain airbag KB. For the sake of illustration, the mounting brackets 41 and 42 are not shown.

  In FIG. 11, an inflator IR that is elongated in the front-rear direction is fixed to the roof side rail 32 via a mounting bracket 43. As shown in FIGS. 4 and 11, etc., an assist grip 36 as a vehicle interior is fixed to the roof side rail 32, and a portion of the assist grip 36 that is gripped by a passenger is -It is exposed to the passenger compartment through the foot trim RT. In the embodiment, the assist grip 36 is disposed so as to be further on the inner side in the vehicle width direction than the inflator IR. For example, the assist grip 36 is disposed between the curtain airbag KB in the stored state and the inflator IR. The arrangement position can be set as appropriate.

  As shown in FIGS. 5 and 13, the front surface portion 26 of the rear pillar trim PT4 is inclined so as to be gradually positioned rearward as it goes outward in the vehicle width direction in a plan view (for example, when viewed from above the vehicle body). The inclined portion 26d is formed. That is, the portion located on the outer side in the vehicle width direction from the folding point 66 at the substantially intermediate position in the vehicle width direction of the front surface portion 26 is the rear inclined portion 26d, and the inclined portion 26d extends from the folding point 66 in the vehicle width direction. As it goes outward, the vehicle is inclined so as to be farther away from a vehicle width direction reference line SHL extending in the vehicle width direction. In the present embodiment, the rear inclined portion 26d is formed substantially linearly, but may be an arc-shaped inclination setting that is convex forward, for example. Further, the rear inclined portion 26d may be formed only in the upper portion of the front surface portion 26. By forming the rear inclined portion 26d, the area of the rear pillar trim PT4 that covers the curtain airbag KB in the housed state from the front is reduced, and the resistance action of the rear pillar trim PT4 is reduced accordingly. The deployability of the curtain airbag KB is improved.

  Next, the arrangement state of the curtain airbag KB in the storage state near the roof side trim RST and the direction of deployment of the curtain airbag KB will be described with reference to FIGS. To do. First, the arrangement state of the curtain airbag KB in the stowed state will be described. As shown in FIG. 13, in the portion along the roof side trim RST, the vehicle is slightly more than the inner side edge in the vehicle width direction. It is arranged so as to extend in the front-rear direction in a substantially straight line (substantially straight) so as to pass through a position closer to the inner side in the width direction, and passes through the inner side in the vehicle width direction of the front pillar trim PT3. Then, the vehicle width is curved toward the outer side in the vehicle width direction in the vicinity of the rear end portion of the roof side trim RST, and the vehicle width is greater at the portion along the rear pillar trim PT4 than at the portion along the roof side trim RST. It is set to be located on the outer side in the direction. The curtain airbag KB in the stored state is disposed in the immediate vicinity of the rear inclined portion 26d, and its deployment orientation direction is set so as to pass through the upper inclined portion 26d. Is in contact with the rear inclined portion 26d. Note that the shape of the rear inclined portion 26d in a plan view can be set as appropriate, such as being formed in a straight line or protruding forward.

  The deployment orientation direction of the curtain airbag KB is set as follows, for example, but the deployment orientation direction of the curtain airbag KB is when the curtain airbag KB is fixed to the vehicle body at a normal mounting and fixing location. If, for example, the curtain airbag KB is folded in a bellows shape from the lower end (lower end in the deployed state) when the curtain airbag KB is deployed, the bellows is extended. The deployment tip side in the direction to perform is the deployment orientation direction. Normally, when folded in a bellows shape in this way, the opposite side to the attachment and fixing portion of the curtain airbag KB is the deployment tip direction in the direction in which the bellows extends, so the opposite side of the attachment and fixing portion is It can also be a deployment-oriented direction. Further, when the curtain airbag KB is rolled up, the opposite side of the curtain airbag KB from the mounting and fixing portion is also the deployment direction.

  First, the direction of deployment of the curtain airbag KB at the front pillar trim PT3 and the portion along the roof side trim RST is directed substantially downward as indicated by an arrow δ1 in FIG. . On the other hand, in the portion along the rear pillar trim PT4, as shown by an arrow γ in FIG. 8, the deployment direction is greatly changed outward in the vehicle width direction, and the vehicle body panel is joined in the deployment direction. The flange portion 23 is set to be positioned (the side window glass G3 is not directly positioned in the development directing direction). Then, as described above, the change in the large deployment direction is as described above. The curtain airbag is in the stored state from the vicinity of the rear end portion of the roof side trim RST to the vicinity of the upper end portion of the rear pillar trim PT4. This is done by twisting the KB.

  As shown in FIGS. 8 and 10, a speaker 51 is disposed in the rear pillar trim PT4. The speaker 51 is fixed to the rear pillar P4 via the mounting bracket 52, and is set so that its directing direction (sound directing direction) is forward. In the rear pillar trim PT4, an opening 53 is formed at a position immediately before the speaker 51, that is, in the front surface portion 26 (see also FIGS. 6 and 7). The opening 53 is configured as an aggregate of a large number of small holes, and is configured so as to form a net-like pattern as a whole and to have a good appearance from the vehicle interior side. The shape and size of the opening 53 correspond to the shape and diameter of the speaker 51, and in the embodiment, the opening 53 has a circular shape with a diameter of about 7 to 10 cm. That is, the opening 53 having a circular outer shape is configured by forming the numerous small holes in a circular area range. The outer shape of the opening 53 can be changed as appropriate, for example, by setting it to an ellipse or a rectangle. Of course, the shape of the large number of small holes can also be an appropriate shape such as a circle, an ellipse, or a rectangle. Thus, since the opening 53 is formed of a large number of small holes, the inside of the rear pillar trim cannot be visually observed from the vehicle interior side (the maximum diameter of the small holes is 1 mm to It is preferable to set within a range of about 3 mm). The vertical position of the opening 53 (speaker 51) is the upper part of the predetermined end edge part 26a of the rear pillar trim PT4 in the front face part 26 (the intersection of the upper edge part and the rear edge part of the side window glass G3). It is set at the lower part so as to be as far away as possible.

  In particular, as shown in FIG. 6, the outer end in the vehicle width direction of the third row seat SC is located near the front surface portion 26 of the rear pillar trim PT4, and in particular, a headrest 54 is located near the head of the passenger. Will be located. Accordingly, the head of the occupant seated on the third row seat SC is positioned near the opening 53, but the sound from the speaker 51 diffused into the vehicle interior through the opening 53 is directed forward. Therefore, it is prevented or reduced that an occupant sitting on the third row seat SC3 listens to the sound from the opening 53 at a high volume and feels uncomfortable. And it is very preferable for the passenger | crew who is seated in the 1st row | line seat SA and 2nd row | line seat | sheet SB used as a front seat that the audio | voice diffused in a vehicle interior through the opening part 53 is directed ahead. It becomes a sound generation mode.

  6, 7, and 10, 55 is a occupant seat belt for the third row seat SC, 56 is a shoulder anchor, and a guide portion of the shoulder anchor 56 to which the seat belt 56 is guided coincides. 56a. The shoulder anchor 56 is positioned on the side surface portion 25 of the rear pillar trim PT4, and its attachment end portion passes through the rear pillar trim PT4 and is fixed to the rear pillar P4. The seat belt 55 extends from a retractor fixed to the vehicle body at a lower portion near the rear pillar trim PT4.

  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 inflated and deployed in the vehicle interior with the shape shown by hatching in FIG.

  Expansion and deployment of the curtain airbag KB into the vehicle interior is performed through a boundary portion between the roof side trim RST and the roof trim RT in a portion along the roof side trim RST. That is, the curtain airbag KB is deployed in the vehicle interior while the roof trim RT positioned at the inner side in the vehicle width direction of the roof side trim RST is deformed downward (the roof side). The side trim RST maintains the state shown in FIG. Since the roof trim RT is soft, it is easily deformed downward, and the interior of the curtain airbag KB is expanded through the boundary between the roof side trim RST and the roof trim RT. Will be performed smoothly.

  Deployment of the curtain airbag KB in the front pillar trim PT3 portion is performed through a boundary portion between the front pillar trim PT3 and the roof trim RT. That is, the curtain airbag KB is deployed in the vehicle interior while the roof trim RT on the inner side in the vehicle width direction of the front pillar trim PT3 is deformed downward. Since the roof trim RT is soft, it is easily deformed downward, and the interior of the curtain airbag KB is expanded through the boundary between the roof side trim RST and the front pillar trim PT3. In particular, the curtain airbag KB can be smoothly deployed while preventing the curtain airbag KB from being caught on the upper end of the front pillar trim PT3.

  Deployment of the curtain airbag KB at the rear end portion of the roof side trim RST is performed through a boundary portion between the rear end portion of the roof side trim RST and the upper end portion of the rear pillar trim PT4. That is, the rear end portion of the roof side trim RST is deformed downward, and is deployed in the curtain airbag KB or the passenger compartment. The roof side trim RST has a particularly thin plate shape, and the fixing portion to the vehicle body is only the front end position, and the rear end portion is not fixed to the vehicle body. The rear end portion is deformed downward relatively easily, and the curtain airbag KB is smoothly deployed. The roof side trim RST has its locking projection 61 firmly locked to the roof side rail 32 (inner panel 31 thereof), and the pressure during expansion and deployment of the curtain airbag KB is reduced. Even if it is received, it is prevented from being displaced downward, but when the pressure at the time of expansion and deployment is received, the locking position of the locking projection 61 with respect to the roof side rail 32 is changed slightly downward. (The roof side trim RST is only displaced downward by a predetermined amount so as not to fall off the roof side rail 32). In this case, the curtain airbag KB is deployed in the passenger compartment. The property becomes even better.

  Deployment of the curtain airbag KB from the rear pillar trim PT4 portion is performed while the front portion 26 is deformed forward as indicated by an arrow β in FIG. 8 (the expanded and deployed curtain airbag KB is a one-dot chain line). Indicated by). 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. . The portion of the curtain airbag KB in the stored state along the rear edge of the side window glass G3 is largely directed outward in the vehicle width direction as indicated by the arrow γ in FIG. The curtain airbag KB that is inflated and deployed into the passenger compartment while deforming 26a has a minimum necessary gap between the predetermined end edge portion 26a and the side window glass G3 to be a passage for the curtain airbag KB. This means that the predetermined end edge portion 26a does not need to be deformed unnecessarily large, and the rear pillar trim PT4 is prevented from being damaged in the vicinity of the predetermined end edge portion 26a. This is preferable.

  In the portion along the rear edge of the side window glass G3, the deployment direction of the curtain airbag KB is the joint flange 23, and is not directly directed to the rear pillar trim PT4 or the side window glass G3. This prevents the PT4 and the side window glass G3 from being damaged by a large pressure during expansion and deployment.

  The rear inclined portion 26d formed on the front surface portion 26 reduces the area of the rear pillar trim PT4 that covers the curtain airbag KB in the housed state from the front, thereby reducing the resistance action of the rear pillar trim PT4. Thus, the deployability of the curtain airbag KB is improved.

  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 greatly caused only in the vicinity, an excessive force (unreasonable deformation) does not act on the predetermined edge 26a (particularly the upper part) and the vicinity thereof, and the predetermined edge 26a and its The situation where the neighborhood is partially damaged 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.

  In addition to the above, the deployment direction of the curtain airbag KB is such that the portion along the upper edge of the side window glass G3 is relatively larger than the portion along the rear edge and faces inward in the vehicle width direction. Therefore, without pressing the side window glass G3 from the vehicle interior side with a large force, the soft roof trim can be easily deformed downward while preventing the side window glass G3 from being damaged. It can be expanded and deployed in the passenger compartment.

  As shown in FIG. 11, the curtain airbag KB in the stored state disposed behind the predetermined edge portion 26a is set to be located on the outer side in the vehicle width direction as much as possible. This is preferable in that the portion 26a is easily deformed as much as possible to improve its developability. In particular, when 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, it is seated on the third row seat SC that is the last row seat. This is also preferable in preventing interference between the occupant and the curtain airbag KB to be expanded and deployed. Of course, in the portion along the rear edge of the side window glass G3, the deployment direction of the curtain airbag KB is the joining flange 23, so that the side window glass G3 is prevented from being damaged.

  In this embodiment, a hard roof side trim RST is present at the rear end of the upper edge of the side window glass G3 in order to extend the curtain airbag KB in the deployment direction. Since the side trim RST is relatively small and easily receives a deployment pressure when the curtain airbag KB is deployed, the side trim RST is easily displaced downward, so that the deployability of the curtain airbag KB is ensured.

  Here, when the angle between the upper edge portion and the rear edge portion of the side window glass G3 is 120 degrees or less (preferably 100 degrees) when viewed from the side of the vehicle width, the stored curtain airbag KB Since the side window glass G3 is disposed substantially along the upper edge and the rear edge of the side window glass G3, the extending direction of the curtain airbag KB stored therein is around the upper end of the predetermined edge 26a of the rear pillar trim PT4. It changes so much that it is bent. Thereby, when the curtain airbag KB is deployed, a downward stress and a front stress act on the periphery of the upper end portion of the predetermined edge portion 26a. On the other hand, the curtain airbag KB is twisted at a portion corresponding to the upper end portion of the predetermined edge portion 26a (near the upper end portion), and the deployment orientation direction is set so as not to substantially intersect with the lower side and the front side. Thus, the stress on the upper end portion of the predetermined edge portion 26a can be reduced to prevent the rear pillar trim PT4 from being damaged.

  FIGS. 14 to 17 show a second embodiment of the present invention. The same components as those of the above embodiment are given the same reference numerals, and a duplicate description thereof is omitted (this is further described in the third embodiment below). The same applies to the following forms). 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. A portion above the intermediate position is constituted by a cover member 27 as a cover portion 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 (semicircular arc shape), for example, with a soft synthetic resin or the like, and is set so 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. In this embodiment as well, the rear pillar trim PT4 is formed with the rear inclined portion 26d, but the inner side edge in the vehicle width direction of the curtain airbag member 27 is near the break point 66 of the rear inclined portion 26d. (See FIG. 15).

  As shown in FIG. 16, the upper end portion (upper end position) of the cover member 27 is positioned below and forward of the rear end portion (rear end position) of the roof side trim RST, that is, more It is set to be close to the room side. Thus, the forward deformation of the cover portion 27 is reliably performed without being obstructed by the roof side trim RST. In other words, the downward deformation of the rear end portion of the roof side trim RST is performed after the cover member 27 is deformed forward and downward. In this case, as viewed from the side of the side window glass G3, the angle between the upper edge portion and the rear edge portion of the side window glass G3 is desirably 90 degrees or more, and at least the cover member 27 is not covered. The extending direction of the front end portion (upper end portion) is preferably in line with the extending direction of the curtain airbag KB in the vicinity of the front end portion.

  FIG. 18 shows a third embodiment of the present invention and shows a modification of FIG. That is, in this embodiment, a portion corresponding to the cover member 27 in FIG. 17 is integrally formed on 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. In FIG. 18, the cover portion 27 ′ when the curtain airbag KB is in the stored state is indicated by a solid line, and the cover portion 27 ′ when the curtain airbag KB is inflated and deployed is indicated by a dashed line.

  FIG. 19 shows a fourth embodiment of the present invention. When the rear pillar trim PT4 receives a predetermined 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. 21 shows a fifth embodiment of the present invention. In the present embodiment, the front portion 26 is set to be inclined so as to be gradually positioned downward as it goes outward in the vehicle width direction when viewed from the front (for example, when viewed from the front of the vehicle body). More specifically, the symbol HL is a horizontal reference line extending in the vehicle width direction, and the front surface portion 26 is located outward from the folding point position indicated by the symbol 65 set near the side surface portion 25 in the vehicle width direction. The lower inclined portion 26c is gradually inclined downward (as it is gradually separated from the horizontal reference line HL) as it goes. A curtain airbag KB in a stored state is disposed immediately after such a downwardly inclined portion 26c (the mounting bracket 41 or 42 is positioned at the front and rear in the cross-sectional position in FIG. 21). The curtain airbag KB in the accommodated state is disposed in the immediate vicinity of the downwardly inclined portion 26c, and its deployment orientation direction is set so as to pass through the downwardly inclined portion 26c. The KB is in contact with the downward inclined portion 26c. In addition, the downward inclination part 26c can set suitably the shape in front view, such as forming linearly or making it convex upward.

  In the embodiment of FIG. 21, the curtain airbag KB to be inflated and deployed is deployed toward the vehicle interior while trying to get over the inclined portion 26c of the front portion 26 of the rear pillar trim PT4. . At this time, the formation of the inclined portion 26c reduces the area portion covering the curtain airbag KB in the stored state from the front as compared with the case where the inclined portion 26c is not formed, and the curtain by the rear pillar trim PT4 correspondingly. The resistance action against expansion and deployment of the airbag KB is small, and the deployability of the curtain airbag KB is ensured satisfactorily. Further, when the curtain airbag KB tries to get over the inclined portion 26c, the curtain airbag KB slides on the inclined portion 26c toward the outer side in the vehicle width direction by setting the inclined direction of the downward inclined portion 26c. Since it is deployed indoors, it is possible to prevent the curtain airbag KB from being caught by the rear pillar trim PT4. As described above, the curtain airbag KB smoothly passes over the rear pillar trim PT4, so that an excessive force does not act on the rear pillar trim PT4, which is preferable in preventing the damage.

  FIG. 22 shows a sixth embodiment of the present invention. This embodiment corresponds to the embodiment shown in FIG. 8, and the deployment orientation direction γ of the curtain airbag KB is set forward.

  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. . Both the lower inclined portion 26c and the rear inclined portion 26d may be formed on the rear pillar trim PT4 (the state is as shown in FIG. 15 in a plan view and the state as shown in FIG. 21 in a front view). The advantage of having both inclined portions 26c and 26d is combined. The location where the deployment orientation direction of the curtain airbag KB in the stored state is greatly changed may be performed in a portion along the upper edge portion of the side window glass G3. In this case, the front end portion to the rear end portion thereof. It can also be changed so that it goes gradually outward in the vehicle width direction toward the rear over almost the entire length (in this case, the deployment direction can be changed as slowly (gradually) as possible. (This is preferable in ensuring better development of the bag KB). In place of the assist grip 36 for a vehicle interior product shown in FIG. 11 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 is provided. Also good. 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. The lower end portion of the inflated and deployed curtain airbag KB is inflated in a state where it is wider in the vehicle width direction than the other portions over almost the entire length thereof, so that it is larger than the external force in the vehicle width direction. It may be possible to resist. The roof side trim RST may be integrally formed with the front pillar trim PT3. 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.
