  The guide wall 30 </ b> D <b> 1 is disposed so as to be inclined such that the inner end in the vehicle width direction is lower than the outer end in the vehicle width direction, and the leading end is the upper end of the B pillar garnish upper 18 and the end of the roof head lining 32. It is arranged to face the part 32A. The hanging wall 30 </ b> D <b> 2 extends downward from the terminal portion 32 </ b> A of the roof head lining 32, and is disposed so as to overlap the outer side in the vehicle width direction with respect to the upper end portion of the B pillar garnish upper 18. As shown in FIG. 3, a rectangular locking hole 36 that is elongated along the vehicle front-rear direction is formed at the lower end of the hanging wall 30 </ b> D <b> 2. The locking hole 36 corresponds to a claw portion 18B provided on the upper end portion of the B pillar garnish upper 18 above the clip support portion 18A.

  The claw portion 18B is formed in a plate shape whose plate thickness direction extends in the vertical direction, and protrudes from the back surface (the surface on the B pillar 12 side) of the B pillar garnish upper 18 toward the B pillar 12 side. It is inserted from the vehicle compartment side into the locking hole 36 of 30D2. The tip portion of the claw portion 18B protrudes to the B pillar 12 side from the hanging wall 30D2, and the tip portion is provided with a barb 18B1 protruding in a cross-sectional triangle toward the upper side. As a result, the claw portion 18B is prevented from inadvertently coming out of the locking hole 36 by the return 18B1 being hooked on the edge of the locking hole 36. Accordingly, the upper end portion of the B pillar garnish upper 18 is locked (connected) to the hanging wall 30 </ b> D <b> 2 of the edge protector 30.

  At the rear end of the edge protector 30, a jump base 30E provided with a guide wall 30E1 that is basically similar to the above-described guide wall 30D1 is provided. The guide wall 30E1 of the jump stand 30E extends from the lower end of the vertical wall 30A2 of the bag protection portion 30A toward the upper end portion of the C pillar garnish (not shown). The C pillar garnish covers a C pillar (not shown) of the vehicle body from the passenger compartment side.

  On the other hand, as shown in FIG. 2, a cylindrical gas supply port 26 </ b> A extends from the longitudinal intermediate portion of the curtain airbag 26. This gas supply port 26A is drawn to the upper side of the upper wall 30A1 through a notch 38 formed in the upper wall 30A1 of the bag protection part 30A of the edge protector 30, and at the tip of the gas supply port 26A, An inflator 28 is connected. The inflator 28 is formed in a substantially cylindrical shape, and is fixed to the side of the vehicle body via a bracket (not shown).

  The inflator 28 is electrically connected to an unillustrated airbag ECU mounted on the vehicle, and an unillustrated side collision detection sensor and rollover sensor mounted on the vehicle are electrically connected to the airbag ECU. It is connected to the. The airbag ECU activates the inflator 28 by energizing the inflator 28 when a side collision state or rollover state of the vehicle is detected by the side collision detection sensor and the rollover sensor. Thereby, the inflator 28 ejects gas into the curtain airbag 26 through the gas supply port 26A.

  Next, the operation and effect of this embodiment will be described.

  In the present embodiment, when the vehicle collides or rolls over, the inflator 28 is actuated by the airbag ECU, and gas is ejected into the curtain airbag 26 via the gas supply port 26A. As a result, the curtain airbag 26 is inflated toward the vehicle compartment while being guided in the direction of inflation by the jump base 30D of the edge protector 30. At this time, the curtain airbag 26 is moved to the vehicle body side by the bag protector 30A of the edge protector 30. Interference with the part is prevented. Therefore, it is possible to prevent the curtain airbag 26 from being damaged due to interference with corners of the vehicle body side (roof side rail, etc.) and burrs. Moreover, since the edge protector 30 is formed of a soft synthetic resin material (so-called TPO) mixed with a rubber material, the curtain airbag 26 can be elastically protected.

  When the curtain airbag 26 is inflated, the terminal portion 32A of the roof head lining 32 is pressed toward the passenger compartment side by the inflation pressure of the curtain airbag 26. Thereby, a side clip (not shown) fixed to the back surface of the terminal portion 32A comes out of the clip hole 22 of the edge protector 30, and the locking of the terminal portion 32A to the edge protector 30 is released. As a result, as shown in FIG. 4, the curtain airbag 26 is deployed in a curtain shape on the lower side of the roof side rail while the terminal portion 32 </ b> A is bent (pushing open) toward the passenger compartment. As a result, the vehicle occupant can be well protected from side impact or rollover impact.

  Here, in the present embodiment, the edge protector 30 described above has a jump base 30D extending from the lower end of the bag protection portion 30A toward the upper end portion of the B pillar garnish upper 18 on the lower side of the curtain airbag 26. is doing. A claw portion 18B provided at the upper end portion of the B pillar garnish upper 18 is inserted into the locking hole 36 formed in the hanging wall 30D2 of the jump base 30D, and the tip portion of the claw portion 18B is inserted into the claw portion 18B. Is provided with a return 18B1. Therefore, as shown in FIG. 5, the B pillar garnish upper 18 locked to the B pillar inner panel 14 by the clip 20 causes the B pillar 12 to deform along with the deformation of the B pillar 12 due to the impact load F at the time of a side collision. Even when the claw portion 18B is detached from the inner panel 14, the barb 18B1 is hooked on the edge of the locking hole 36 to prevent the upper end portion of the B pillar garnish upper 18 from being separated from the tip end portion of the jump base 30D. Is done. As a result, when the curtain airbag 26 is inflated and deployed, the jump base 30D can prevent the curtain airbag 26 from entering between the B pillar garnish upper 18 and the B pillar inner panel 14.

  That is, as in the comparative example shown in FIG. 7, in the configuration in which the jump stand 18 </ b> C is integrally formed at the upper end of the B pillar garnish upper 18, the B pillar garnish upper is accompanied by the deformation of the B pillar 12 at the time of a side collision. When 18 is removed from the B-pillar inner panel 14, a gap 42 is generated between the B-pillar garnish upper 18 and the B-pillar inner panel 14, and the curtain airbag 26 may enter the gap 42. (Refer to the curtain airbag 26 shown by a solid line in FIG. 7. In FIG. 7, the curtain airbag 26 is normally inflated by a two-dot chain line.

  In this respect, in the present embodiment, since the return 18B1 of the claw portion 18B is caught on the hole edge of the locking hole 36 as described above, the separation between the B pillar garnish upper 18 and the jump base 30D is prevented. As shown in FIG. 5, the curtain airbag 26 can be appropriately inflated and deployed in the vehicle interior.

  Moreover, in the present embodiment, the return 18B1 protrudes upward from the claw portion 18B. For this reason, when the B pillar 12 is greatly deformed locally at the time of a so-called pole side collision, the B pillar garnish upper 18 falls off obliquely upward on the vehicle interior side with respect to the B pillar inner panel 14 (FIG. 5 (see arrow A in FIG. 5), the return 18B1 of the claw portion 18B is satisfactorily hooked to the hole edge of the locking hole 36 of the jump base 30D. That is, in this case, the B pillar garnish upper 18 is dropped in the direction in which the barb 18B1 is hooked on the edge of the locking hole 36, so that the separation between the B pillar garnish upper 18 and the jump base 30D can be satisfactorily prevented. . Thereby, the curtain airbag 26 can be further prevented from entering between the B pillar garnish upper 18 and the B pillar inner panel 14.

  In the present embodiment, when the B pillar garnish upper 18 is assembled to the B pillar inner panel 14 at the time of manufacturing the vehicle, the clip 20 provided on the B pillar garnish upper 18 is attached to the clip hole of the B pillar inner panel 14. 22 and the claw portion 18B provided at the upper end portion of the B pillar garnish upper 18 only needs to be inserted into the locking hole 36 of the jumping base 30D, so the set of the B pillar garnish upper 18 to the B pillar inner panel 14 Installation workability is extremely easy.

  That is, as in the comparative example shown in FIGS. 8A and 8B, in the configuration in which the jump stand 18C is integrally formed at the upper end of the B pillar garnish upper 18, the B pillar garnish upper 18 is When assembled to the pillar inner panel 14, it is necessary to assemble the jump base 18 </ b> C integrated with the B pillar garnish upper 18 into the narrow gap between the roof head lining 32 and the B pillar inner panel 14. At this time, the rib 18C1 provided on the back side of the jump base 18C hits the bulging portion 14A of the B pillar inner panel 14, so that the assembling work is very difficult. In this respect, in this embodiment, since the jump table 30D is formed integrally with the edge protector 30, it is not necessary to push in the jump table 30D as described above, and as a result, the B pillar garnish upper 18 is assembled. The sex can be greatly improved.

  Further, in the comparative example shown in FIGS. 8 (A) and 8 (B), first, as shown in FIG. 8 (A), the jump stand 18C is moved between the roof head lining 32 and the B pillar inner panel 14. Then, as shown in FIG. 8B, the B pillar garnish upper 18 is rotated to the B pillar inner panel 14 side around the jump base 18C side, whereby the clip 20 is moved to the B pillar inner panel 14. Must be inserted into the clip hole 22. In this case, as shown in FIG. 9, since the clip 20 is inserted obliquely with respect to the clip hole 22, the assembly load becomes very high. Moreover, since this insertion work needs to be performed in the state where the clip 20 and the clip hole 22 are not visible due to the shadow of the B pillar garnish upper 18, there is a problem that the assembling workability is extremely poor.

  In this respect, in the present embodiment, when the B pillar garnish upper 18 is assembled, the B pillar garnish upper 18 is maintained in the vehicle width direction while maintaining the mounting posture to the B pillar inner panel 14 as shown in FIG. What is necessary is just to make it approach the B pillar inner panel 14 straight toward the outer side. Thereby, since the clip 20 is inserted straight into the clip hole 22 and the claw portion 18B is inserted straight into the locking hole 36, an increase in assembly load can be avoided. Therefore, the assembling workability can be remarkably improved also by this.

  In this embodiment, the jump stand 30D of the edge protector 30 has a hanging wall 30D2 extending downward from the tip of the guide wall 30D1 that guides the inflation direction of the curtain airbag 26, A locking hole 36 is formed on the lower end side of the hanging wall 30D2. As a result, the locking hole 36 is disposed below the terminal portion 32A of the roof head lining 32, so that the claw portion 18B of the B pillar garnish upper 18 is inserted into the locking hole 36 when the roof head lining is inserted. 32 does not get in the way. Therefore, the assembly workability can be improved also by this. In addition, since the jump base 30D has ribs 30D3 that span the lower surface of the guide wall 30D1 and the outer surface in the vehicle width direction of the hanging wall 30D2, the mass of the edge protector 30 including the jump base 30D is large. While suppressing the increase, the rigidity of the jump base 30D can be ensured by the rib 30D3.

  Further, in the present embodiment, the rib 30D3 of the jump base 30D is disposed in contact with the upper surface of the bulging portion 14A provided on the B pillar inner panel 14, so that the curtain airbag 26 is inflated when the curtain airbag 26 is inflated and deployed. The load input from 26 to the jump base 30D can be favorably supported by the bulging portion 14A. Thereby, since the deformation | transformation of the jump stand 30D can be suppressed, the inflation direction of the curtain airbag 26 can be accurately guided by the jump stand 30D.

  In the above embodiment, the rib 30D3 of the jump base 30D is disposed in contact with the upper surface of the bulging portion 14A provided in the B pillar inner panel 14, but the invention according to claim 1 Not limited to this, the jump stand may be disposed in contact with the upper part of another member attached to the B pillar inner panel 14.

  Moreover, in the said embodiment, although the jump stand 30D was equipped with the guide wall 30D1 and the hanging wall 30D2, and it was set as the structure which the locking hole 36 was formed in this hanging wall 30D2, the invention which concerns on Claim 1 is not restricted to this The jump base may be any one as long as a locking hole is formed on the tip side, and the configuration can be changed as appropriate.
