Furthermore, when the locked state can be maintained by the two locking claws 32, only the scattering prevention claw 38 may be provided without providing the locking claw 36.

(Action and effect)
Next, the operation and effect of the present embodiment will be described while explaining the state in which the interior material fixture 10 is attached to the ceiling lining material 100. As shown in FIG. 3, a bolt 108 as a fastener is inserted into the fixing portion 12 of the interior material fixture 10, and the ceiling lining material 100 is fixed to the vehicle body 102 with this bolt 108. Specifically, the bracket 104 is connected to the vehicle body 102, and the bolt 108 is inserted into the bolt hole 20 </ b> C of the fixed seat 20 from the vehicle interior side with the ceiling lining material 100 pressed against the bracket 104. The ceiling lining material 100 is fixed to the vehicle body 102 by being screwed into a welded weld nut 106.

  In this state where the ceiling lining material 100 is fixed to the vehicle body 102, the fixed seat 20 is fastened to the bracket 104 with the bolts 108. Therefore, even if a load is applied to the fixed seat 20, the fixed seat 20 is fixed to the ceiling lining material. The deviation from 100 can be suppressed. Further, after the fixing portion 12 is fastened to the bracket 104 with the bolts 108, when the cover portion 14 is attached to the fixing portion 12 from the vehicle interior side, the locking claw 32 of the cover portion 14 is inserted into the insertion hole 26A and locked. The portion 32 </ b> A is locked to the back side of the insertion portion 26. In this state, since the bolt 108 is covered with the cover portion 14, the bolt 108 is not visible to the occupant, and the appearance can be maintained satisfactorily. Note that the two-dot chain line in FIG. 3 shows the cover portion 14 before being attached to the fixing portion 12.

  Further, as shown in FIG. 4, when the cover portion 14 is attached to the fixing portion 12 (the cover portion 14 is closed), the temporarily fixing claw 24 protruding from the base 18 is inserted into the bracket 104. And can be temporarily fixed. Thereby, before the bolt 108 is inserted, the fixing portion 12 can be temporarily fixed to the bracket 104 in advance for positioning, so that the efficiency of the assembling work can be improved.

  When the cover portion 14 is closed, the rib 34 projecting from the cover portion 14 is in a state of facing the fixed portion 12 and functions as a stopper. That is, when a load is applied to the cover portion 14 from the vehicle interior side, the rib 34 can be prevented from coming into contact with the fixed portion 12 and the cover portion 14 being pushed more than necessary.

  Further, as shown in FIG. 5, the locking claw 36 is inserted into the through hole 28, and the locking portion 36 </ b> A is locked on the back side of the base 18. Further, the scattering prevention claw 38 formed integrally with the locking claw 36 extends to the vehicle exterior side from the locking claw 36, and the front end portion of the scattering prevention claw 38 passes through the through hole 28 and is attached to the ceiling lining material. It is located on the back side of 100. Here, since the outer peripheral surface of the main body portion 38A of the anti-scattering claw 38 is curved in accordance with the rotation path of the cover portion 14, when the cover portion 14 is rotated around the integral hinge 16, the main body portion 38A. Is less likely to interfere with the fixed portion 12. Thereby, the scattering prevention nail | claw 38 can be smoothly inserted in the through-hole 28 without resistance.

  Further, as shown in FIG. 6, the anti-scattering pin 38 </ b> B provided at the tip of the anti-scattering pawl 38 is inserted to the back surface side of the ceiling lining material 100 while being bent and deformed against the hole wall of the through hole 28. . On the other hand, as shown in FIG. 2, a receiving portion 40 protrudes from the back surface of the base 18, and the receiving portion 40 and the anti-scattering pin 38 </ b> B overlap in the thickness direction of the interior material fixture 10. Is located. Thereby, when the cover part 14 moves in the direction away from the fixed part 12, the scattering prevention pin 38 </ b> B hits the receiving part 40 and is locked, and the cover part 14 can be prevented from being detached from the fixed part 12. In particular, when the airbag is deployed, an excessive load is applied to the cover portion 14, so that it is necessary to receive the anti-scattering pin 38B at the initial stage when the anti-scattering pawl 38 moves. For this reason, by providing the receiving portion 40 on the back surface of the base 18, it is possible to receive the anti-scattering pins 38 </ b> B at an earlier timing than when there is no receiving portion 40, and the anti-scattering effect can be enhanced.

  In the present embodiment, as an example, the receiving portion 40 is integrally formed with the base 18 and resin. However, the present invention is not limited to this, and a member having a high elastic modulus such as rubber so as to reduce the impact of the anti-scattering pin 38B. May be formed.

  Here, with reference to FIG.7 and FIG.8, the behavior of the interior material fixture 10 before and after deployment of the curtain shield airbag 110 will be described. As shown in FIG. 7, a bolt 108 is inserted into the fixing portion 12 of the interior material fixture 10, and the ceiling lining material 100 and the vehicle body 102 are fixed via a bracket 104. Moreover, the cover part 14 is attached to the fixing | fixed part 12 from the vehicle interior side, and the latching claw 32 and the latching claw 36 of the cover part 14 are latched by the fixing | fixed part 12 (refer FIG.3 and FIG.5). ).

  Further, the scattering prevention claw 38 extends through the through hole 28 to the back side of the ceiling lining material 100 (see FIG. 5). When the curtain shield airbag 110 is deployed in this state, as shown in FIG. 8, the airbag bag body 110 </ b> A is inflated and the locked state between the ceiling lining material 100 and the opening trim 112 is released. Then, the airbag lining 110A is deployed by spreading the ceiling lining material 100 toward the vehicle interior side.

  Here, the load when the curtain shield airbag 110 is deployed is transmitted to the interior material fixture 10 via the ceiling lining material 100. When the load is large, the integral hinge 16 that connects the fixed portion 12 and the cover portion 14 is cut. Further, the locking state of the locking claw 32 and the locking claw 36 and the fixing portion 12 is released, and the cover portion 14 moves away from the fixing portion 12. At this time, the anti-scattering pin 38B at the tip of the anti-scattering claw 38 is prevented from coming into contact with the receiving portion 40 and preventing the anti-scattering claw 38 from coming off the through hole 28. Thereby, it can suppress that the cover part 14 scatters to the vehicle interior side. Moreover, since the fixing | fixed part 12 is fastened by the bracket 104 with the volt | bolt 108, even if the curtain shield airbag 110 expand | deploys, it can suppress that the fixing | fixed part 12 scatters to the vehicle interior side.

  When the integral hinge 16 is not cut, the cover portion 14 tries to move away from the fixing portion 12 while rotating around the integral hinge 16, but the scattering prevention pin 38B hits the receiving portion 40 and is locked. Further, the cover portion 14 can be prevented from scattering toward the vehicle interior side. Further, when a load smaller than the load at the time of deployment of the curtain shield airbag 110 is applied to the interior material fixture 10, the locked state of the locking claw 32 and the locking claw 36 and the fixing portion 12 is maintained. Therefore, the cover part 14 does not scatter to the vehicle interior side.

  As mentioned above, although the interior material fixing tool 10 and the interior material fixing structure 50 according to the embodiment of the present invention have been described, it is needless to say that the present invention can be implemented in various modes without departing from the gist of the present invention.
