The latching portion is inserted into the elongated hole in a free state. It is impossible to insert into the long hole from the outside of the side wall by changing the direction, and it is hooked on the periphery of the long hole from the inside of the side wall so as not to come out of the long hole by returning to the original direction. It is characterized by that.

  The invention according to claim 5 is the invention according to any one of claims 1 to 4, wherein the interior trim body is a front pillar trim on a side of a vehicle body, and the clip mounting seat is formed of the interior trim body. It is formed in the upper end part.

  According to the first aspect of the present invention, when the airbag is inflated in a state where the clip is inserted and locked in the clip locking hole of the vehicle body panel, one end in the width direction of the interior panel body is bent by the expansion pressure, Following the bending operation, the slide member slides and disengages from the clip, and the clip is detached from the clip mounting seat. Thereby, the interior trim main body is displaced in a state of being bent toward the vehicle interior side. This displacement is allowed by the extension of the connecting member. Therefore, the bending operation of the interior trim main body is not hindered, and the airbag is likely to expand. Further, the above-described displacement of the interior trim body absorbs and reduces the impact caused by the inflation pressure of the airbag on the interior trim body, so that the interior trim body is prevented from being damaged.

  Furthermore, since the clip and the clip mounting seat are connected by the connecting member, the interior trim body and the vehicle body panel are connected via the connecting member even if the slide member is detached from the clip when the airbag is inflated. Therefore, the interior trim main body is prevented from scattering into the vehicle interior due to the inflation of the airbag.

  According to the second aspect of the present invention, since the slider portion is held by the base portion and the pair of holding piece portions at the time of flatness, the assembled state is stabilized, while the airbag portion is inserted into the insertion space when the airbag is inflated. Slide out smoothly from the clip.

  According to the invention which concerns on Claim 3, a slide member can be easily attached to a clip attachment seat by inserting an engagement shaft part into the engagement hole from the open | release side. Also, as a result, both clamping pieces hold the seat surface of the clip mounting seat from both the inside and outside (front and back) sides, so that the slide member can move inside and outside the seat surface of the clip mounting seat even when impacted by a side collision. There is no way out. Furthermore, since the engagement hole is opened in a direction along one end portion in the width direction, that is, in a direction different from the sliding direction of the sliding member, the sliding member follows the bending operation of the interior trim body at the time of a side collision. Even if the slide slides, the engagement shaft portion does not come out of the engagement hole, and the slide member does not come off from the clip mounting seat.

  According to the invention of claim 4, by changing the direction of the latching portion, that is, when attaching the connecting member coupled to the clip to the clip mounting seat, the clip is rotated or the latching portion is pinched with fingers. By changing the position, insert the latching part into the long hole from the outside of the side wall, rotate the clip in the inserted state and return to the original direction or release the finger from the latching part to apply external force to the latching part. By stopping the hook, the hook portion can be hooked from the inside of the side wall to the periphery of the long hole. Therefore, the latching portion can be easily attached to the clip attachment seat so that it does not come out of the long hole even if the airbag is inflated at the time of a side collision.

  According to the invention of claim 5, the upper end portion of the front pillar trim is reliably bent, the airbag can be surely inflated, and scattering of the interior trim body can be prevented. Can protect.

Is covered from the inside of the passenger compartment 1. 3 and 4 show the front pillar 15, 11 is an inner panel, and 13 is an outer panel. The center pillar and the rear pillar are similarly configured by an inner panel and an outer panel, but are not shown. In FIG. 1, reference numeral 9 denotes a top ceiling (ceiling interior material) disposed above the trims 3, 5, and 7.

  As shown in FIGS. 3 and 4, the front pillar trim 3 includes a front pillar trim body 4 as an interior trim body, and a space between the front pillar trim body 4 (hereinafter simply referred to as a trim body) and the inner panel 11. It is attached to the inner panel 11 so that the portion 17 is formed. As shown in FIG. 2, the air bag 19 is stored in the space portion 17 so as to be positioned on the one side end portion 21 side in the width direction of the trim body 4. The vicinity of the one end portion 21 of the trim body 4 is bent as indicated by a phantom line in FIG. 4, and the airbag 19 bulges into the passenger compartment 1 although not shown.

  A plurality of ribs 23 are provided on the back surface of the trim body 4 so as to extend in the width direction so as to extend in the width direction, and on the upper end side, as shown in FIG. 25 is integrally projected so that 25 may be located in the width direction other end part 22 side (inner side) rather than the airbag 19. As shown in FIG. The clip mounting seat 25 has a rectangular seat surface 29, and the seat surface 29 is formed so as to be separated from the back surface of the trim body 4 by a side wall 33 having a substantially U-shaped cross section. Yes. A circular engagement hole 27 is formed in the seat surface 29, and the insertion hole 28 is opened in the engagement hole 27 in a direction along the one side end portion 21 (flexible end portion) of the trim body 4. The interval between the insertion openings 28 is set to be shorter than the opening diameter of the engagement hole 27, and a tapered guide surface is formed so that the opening width gradually increases toward the outside of the engagement hole 27. Yes. The side wall 33 opens in the opening direction of the engagement hole 27 (on the insertion port 28 side), and faces the first side wall 33a located on the opposite side of the opening direction and the first side wall 33a. And a pair of second side walls 33b. A long hole 31 extending in the protruding direction of the clip mounting seat 25 is formed in the first side wall 33a. A clip 39 is attached to the clip mounting seat 25 via a slide member 35, and a clip locking hole 37 into which the clip 39 is inserted and locked is formed in the clip mounting seat 25 in the inner panel 11. It is formed to correspond.

  As shown in FIG. 6, the clip 39 is inserted into the clip locking hole 37, and has a clip insertion portion 41 having a quadrangular pyramid shape at the tip and a quadrangular prism shape. On both sides in the width direction, locking claws 41a surrounded by a pair of slits 41b are formed so as to be bent outwardly. A rectangular plate-like base portion 43 is integrally formed on the base end of the clip insertion portion 41, that is, on the space portion 17 side of the clip insertion portion 41, and the trim main body is formed at both ends of the base portion 43. A pair of substantially L-shaped holding piece portions 45 which are bent toward the four sides and have receiving portions 45a extending so as to approach each other in parallel with the base portion 43 are provided to project from each other. An insertion space 47 is formed between the base portion 43 and the holding piece portions 45 so as to open to the width direction and the back surface side of the trim body 4.

  Further, in the vicinity of the lower end portion of the trim main body 4 in the base portion 43, that is, in the vicinity of the holding piece portion 45 side of the trim main body 4 on the side opposite to the upper end portion of the pair of holding piece portions 45, the resin can be extended. One end of the flexible strip-like connecting member 63 is integrally connected. The connecting member 63 is bent and bent in the middle (so-called sagging state), and the other end bulges to form a rectangular hook 65. Specifically, the latching portion 65 is formed so that its longitudinal direction is parallel to the width direction of the connecting member 63 in a free state, that is, orthogonal to the longitudinal direction (extension direction) of the connecting member 63. The length in the longitudinal direction is set longer than the short diameter of the long hole 31 and shorter than the long diameter of the long hole 31. The length in the width direction is set to be shorter than the short diameter of the long hole 31. Therefore, in a state where the clip 39 is attached to the clip attachment seat 25 via the slide member 35, the latching portion 65 cannot be inserted into the long hole 31 in the free state. Further, the latching portion 65 is in the state where the clip 39 is not inserted into the clip locking hole 37 of the inner panel 11 and is not attached to the clip mounting seat 25 via the slide member 35. The retaining portion 65 can be inserted into the long hole 31 from the outside of the side wall 33 by changing the direction of the clip 39 so that the longitudinal direction of the clip 39 is along the vertical direction of the long hole 31. Further, by rotating the clip 39 so that the longitudinal direction of the latching portion 65 is directed to the short diameter direction of the long hole 31 with the latching portion 65 being inserted inside the side wall 33 in this way, The latching portion 65 is latched on the periphery of the long hole 31 from the inside of the first side wall 33 a, and does not come out of the long hole 31. In this latched state, the connecting member 63 is bent (slack) and can be extended. Thus, the connecting member 63 can be attached to the clip mounting seat 25 by a simple operation.

On the other hand, as shown in FIGS. 6 and 7, the slide member 35 is configured so that the interior trim body intersects the insertion direction of the clip 39 with respect to the insertion space 47 from the one end portion 21 side of the trim body 4. 4, a substantially rectangular plate-like slider portion 49, which is detachably inserted in the width direction of 4 and held by a pair of holding piece portions 45, and is integrally formed on the trim body 4 side of the slider portion 49, and the clip A fitting body 50 fitted to the mounting seat 25 is provided. The fitting body 50 has a pair of plate-shaped sandwiching piece portions 51 parallel to the slider portion 49, and the slider portion 49 and the sandwiching piece portion 51 on the slider portion 49 side are integrally connected by a support portion 55. A gap 56 corresponding to the thickness of the receiving portion 45a of the clip 39 (holding piece portion 45) is formed between the two. The support portion 55 has substantially the same thickness as the gap 56, and the width of the slide member 35 in the direction orthogonal to the slide direction is substantially equal to the distance between the pair of receiving portions 45 a of the clip 39. In addition, one end of the pair of sandwiching piece portions 51 on the side opposite to the connecting member 63 is connected by the connecting portion 52 and the other end is opened, thereby forming the fitting body 50 in a U shape. In addition, the middle is connected by a cylindrical engaging shaft portion 53. Since the diameter of the engagement shaft portion 53 is set slightly longer than the interval (minimum interval) between the insertion ports 28 of the engagement holes 27 of the clip mounting seat 25, the engagement shaft portion 53 has an engagement hole. When being inserted into 27, the insertion opening 28 is expanded and passed through the insertion opening 28. That is, the engagement shaft portion 53 is press-fitted into the insertion port 28.

  In the vicinity of both side edges along the insertion direction of the surface of the slider part 49 facing the base part 43, a pair of rattling prevention protrusions 57 extending along the both side edges protrudes integrally with a gap therebetween. It is installed. In addition, a pair of stopper portions 61 project at right angles to the respective side edges on both sides of the rear end of the slider portion 49 in the insertion direction. Further, on both sides of the front end of the slider portion 49 in the insertion direction, a pair of guide portions 59 each having an inclined surface 59a inclined outward with respect to the insertion direction are provided so as to protrude from the respective side edges. The inclined surface 59 a is formed on the side of the guide portion 59 opposite to the slider portion 49 in the insertion direction. The protruding length of the stopper portion 61 is set longer than the protruding length of the guide portion 59. The slider portion 49 is detachably inserted into the insertion space 47 of the clip 39. In this state, the protrusion 57 abuts against the back surface of the base portion 43, so that the clip 39 and the slide member 35 are assembled without rattling. It is done. Further, when the slider portion 49 is inserted into the insertion space 47, the guide portion 59 presses the holding piece portions 45 in directions away from each other to be bent, so that the slider portion 49 is press-fitted into the insertion space 47. When the guide portion 59 exits the insertion space 47, both the holding piece portions 45 are released from the insertion pressure and returned to the original interval. As a result, as shown in FIG. 7, both guide portions 59 abut and lock both holding piece portions 45 at the front end in the insertion direction, and both stopper portions 61 abut both holding piece portions 45 at the rear end in the insertion direction. It will be in the state to lock. That is, the slider portion 49 is locked so as not to come out of the insertion space 47. At this time, the receiving portion 45a of the clip 39 is inserted into the gap 56 between the slider portion 49 and the holding piece portion 51 on the slider portion 49 side. On the other hand, when a force to move the slider portion 49 in the anti-insertion direction is applied in this state, the inclined surfaces 59a are formed on the both guide portions 59, so that both guide portions 59 separate the holding piece portions 45 from each other. By being pressed and bent, it is press-fitted into the insertion space 47, and the entire slider portion 49 can come out of the insertion space 47, and then both the holding piece portions 45 are released from the insertion pressure and returned to the original interval. Thereby, the clip 39 and the slide member 35 are separated.

  Further, the engaging shaft portion 53 of the fitting body 50 is inserted and engaged with the engaging hole 27 of the clip mounting seat 25 from the insertion port 28 side (the direction along the one end portion 21), whereby the slide member 35 is engaged. Is assembled to the clip mounting seat 25. Thereby, the seat surface 29 is clamped by the both clamping pieces 51 from both the inside and outside, and the assembled state is stabilized. Further, since the interval between the insertion ports 28 is set slightly shorter than the diameter of the engagement shaft portion 53, the engagement shaft portion 53 is press-fitted into the insertion port 28, and once passes through the insertion port 28, the engagement hole When it is inserted into 27, the engagement shaft portion 53 is difficult to come out from the insertion port 28 side. Further, since both the sandwiching piece portions 51 of the fitting body 50 in the slide member 35 sandwich the seat surface 29 of the clip mounting seat 25, the slide member 35 does not come out inward and outward of the seat surface 29.

  The front pillar trim 3 is attached to the inner panel 11 of the front pillar 15 using the clip 39 and the slide member 35 as follows.

  First, as described above, the latching portion 65 of the connecting member 63 is inserted into the elongated hole 31 of the clip mounting seat 25 so as to be latched on the periphery of the elongated hole 31 from the inside of the first side wall 33a. In this state, the connecting member 63 is bent and can be extended.

  Next, the slide member 35 is assembled to the clip 39. The assembly is performed by inserting the slider portion 49 of the slide member 35 into the insertion space 47 of the clip 39 so that the holding piece portion 45 of the clip 39 is sandwiched between the stopper portion 61 and the guide portion 59. The slider portion 49 is locked by the stopper portion 61 and the guide portion 59 so as not to come out of the insertion space 47, and the slide member 35 is prevented from being detached from the clip 39.

  Further, the engagement shaft portion 53 of the fitting body 50 in the slide member 35 is made to correspond to the engagement hole 27 of the clip mounting seat 25, in the direction along the one side end portion 21 of the trim body 4, that is, the engagement hole 27. The slide member 35 is attached to the clip attachment seat 25 by inserting from the open side and holding the seat surface 29 from both the inside and outside by the both holding pieces 51.

  Accordingly, the clip 39 is attached to the front pillar trim 3 in a state where it can be extended by the connecting member 63 with respect to the front pillar trim 3, and is attached to the front pillar trim 3 via the slide member 35.

  Finally, the clip insertion portion 41 of the clip 39 attached to the front pillar trim 3 via the slide member 35 as described above is positioned so as to correspond to the clip locking hole 37 of the inner panel 11, and the front pillar trim 3 is attached. The clip insertion portion 41 is inserted into the clip locking hole 37 by pressing from the inside of the passenger compartment 1. Specifically, by the pressing, the pair of locking claws 41a of the clip insertion portion 41 is bent inward, and the clip insertion portion 41 is inserted into the clip locking hole 37 up to the proximal end, and then the locking claws 41a are moved outward. And the periphery of the clip locking hole 37 is locked (clamped) by the locking claw 41 a and the base portion 43 of the clip 39, so that the entire clip insertion portion 41 cannot be removed from the clip locking hole 37. . As a result, the front pillar trim 3 is attached to the inner panel 11 so as not to move during normal times.

  Although not shown, the front pillar trim 3 is attached to the inner panel 11 with a fastening member near the lower end thereof.

When the airbag 19 is inflated in such an attachment state at the time of a side collision, the one side end portion 21 of the trim body 4 is bent as shown by an imaginary line in FIG. 4 due to the inflation pressure, and the clip 39 and the clip attachment seat 25 are 8 extends as shown in FIG. 8, and the slider portion 49 of the slide member 35 comes out of the insertion space 47 of the clip 39 following the bending operation. Specifically, when the one side end portion 21 is bent, the clip mounting seat 25 is inclined so that the position of the second side wall 33b on the one side end portion 21 side is lowered. An acting force from the other end 22 of the trim body 4 to the one end 21 is applied to the attached slide member 35. Here, the clip 39 is attached to the inner panel 11, and the sliding direction of the slider portion 49 of the slide member 35 in the insertion space 47 coincides with the acting direction of the acting force. Therefore, the slider portion 49 pushes and widens the other end 22 side of the trim main body 4 of the holding piece portion 45 by the inclined surface 59 a of the guide portion 59, so that the guide portion 59 is within the insertion space 47 of the holding piece portion 45. As a result, the slider portion 49 slides in the insertion space 47 (in the holding piece portion 45) in the direction in which the acting force is applied, that is, in the width direction one end portion 21 side direction of the trim body 4, and the clip 39 ( It is detached smoothly from the holding piece 45). At this time, since the insertion port 28 of the engagement hole 27 is opened in a direction different from the sliding direction of the slide member 35, the engagement shaft portion 53 does not move even if the slider portion 49 of the slide member 35 slides. The slide member 35 does not come off the clip mounting seat 25 without coming out of the engagement hole 27. When the slide member 35 is detached from the clip 39, the trim body 4 is separated from the inner panel 11 in the vicinity of the clip 39 and the clip mounting seat 25 than before the airbag 19 is inflated, as shown in FIG. 8. Thus, since the trim main body 4 is separated from the inner panel 11, the airbag 19 is easily expanded. Further, since the trim body 4 is separated from the inner panel 11, the impact due to the inflation pressure of the airbag 19 is relaxed and absorbed, so that the trim body 4 is prevented from being damaged. At this time, as shown in FIG. 8, the clip 39 remains inserted and locked in the clip locking hole 37 of the inner panel 11, and the connecting member 63 extends, so that the latching portion 65 of the connecting member 63 is The connecting state of the clip 39 to the clip mounting seat 25 is maintained by the connecting member 63 without coming out of the long hole 31. That is, the trim body 4 and the inner panel 11 are connected via the connecting member 63. Therefore, even if the trim main body 4 in the vicinity of the clip mounting seat 25 is damaged by the expansion pressure, the trim main body 4 is prevented from being scattered into the passenger compartment 1 by the expansion pressure, and the driver seat and the assistant in the passenger compartment 1 are prevented. Seat occupants are protected.

  In the above embodiment, an example in which the present invention is applied to the front pillar trim 3 has been described. However, the present invention can also be applied to other pillar trims such as the rear pillar trim 7.

  In the above embodiment, as a method of attaching the connecting member 63 connected to the clip 39 to the clip mounting seat 25, the latching portion 65 is attached in a state where the clip 39 is not attached to the clip mounting seat 25 via the slide member 35. The direction of the clip 39 is rotated so that the longitudinal direction of the clip 39 corresponds to the longitudinal direction of the long hole 31, and the latching portion 65 is inserted into the long hole 31. By rotating the clip 39 so as to face, the latching portion 65 is latched on the peripheral edge of the long hole 31. However, after attaching the clip 39 to the clip mounting seat 25 via the slide member 35, the hook 65 is pinched with a finger and the orientation is changed so that the longitudinal direction thereof corresponds to the longitudinal direction of the long hole 31. After the insertion into 31, the hook 65 may be restored to the original direction by the restoring force of the connecting member 63 by releasing the finger.

  Moreover, in the said embodiment, when attaching the connection member 63 to the clip attachment seat 25, the latch part 65 was latched on the periphery of the long hole 31 in the state which has not attached the slide member 35 to the clip 39, With the slide member 35 attached to 39, the latching portion 65 may be latched on the periphery of the long hole 31 by the same method as in the above embodiment.
