JP 2006-207607 A

However, the conventional CSA attachment clip has the following problems.
(I) It is difficult to narrow the A-pillar garnish, and there is room for improving the visibility.
That is, in FIG. 9, the side wall 107b rises from the entire circumference of the bottom wall 107a of the head 107 of the clip body 101, and the peripheral wall 104a of the lock pin insertion jig 104 only fits around the side wall 107b. Space is required. Therefore, it is difficult to bring the CSA 105 closer to the axis 109 side of the clip body 101 in the direction P orthogonal to the CSA longitudinal direction (same as the A pillar longitudinal direction). At most, between the outer surface of the CSA 105 and the shaft core 109 of the clip 100, in the direction P perpendicular to the CSA longitudinal direction, half the width of the clip head 107 and the peripheral wall of the lock pin insertion jig 104 A distance that is the sum of the thickness of 104a is required. As a result, it is difficult to reduce the width of the A pillar garnish 103.

(Ii) Since the A pillar garnish 103 is attached to the inner panel 106a of the A pillar 106 after the lock pin 102 is pushed into the clip body 101, two steps are required for pushing the lock pin 102 and attaching the A pillar garnish 103. Become. Further, it is necessary to confirm whether or not the lock pin 102 is pushed in securely. As a result, there is room for improvement in the work efficiency of inserting the lock pin 102 and attaching the A pillar garnish 103.

The first object of the present invention is to support CSA closer to the axial center of the clip than in the case of CSA support using a conventional clip, and thus to narrow the A-pillar garnish, thereby improving the driver's visibility. An object of the present invention is to provide a CSA attachment device that can perform the above-described process.
The second object of the present invention is to provide a CSA that can support the CSA closer to the axial center of the clip than in the case of CSA support by a conventional clip, and can improve the working efficiency of pushing the lock pin and attaching the A pillar garnish. To provide an attachment device.

  The CSA attachment device of the present invention that solves the above problems or achieves the above object is as follows.

(1) The CSA attachment device of the present invention is a CSA attachment device for attaching a CSA to a vehicle body member at a tab portion, and has a clip body.
The clip body has a head and legs.
The head has a seat parallel to the clip mounting surface of the body member, and a vehicle inner side (a part of the head other than the seat) extending in the opposite direction from the leg.
The vehicle inner side portion has a narrow width portion whose width is narrower than the seat portion in a direction perpendicular to the CSA longitudinal direction.

(2) In the CSA attachment device according to (1), the vehicle inner side portion includes the narrow portion and a connecting portion that connects the narrow portion and the seat portion.
The width of the connecting portion in the direction orthogonal to the CSA longitudinal direction increases from the narrow portion to the seat portion.

(3) In the CSA attachment device of (1), the CSA attachment device further includes a lock pin.
The clip body has a lock pin insertion hole in the center.
The vehicle inner side portion has a first groove extending through the center portion in a direction parallel to the CSA longitudinal direction.

(4) In the CSA attachment device of (3) above, the vehicle inner side portion extends across the first groove in a direction orthogonal to the first groove on both sides of the central portion in a direction parallel to the longitudinal direction of the CSA. Has ribs.

(5) In the CSA attachment device of (1), the CSA attachment device further includes a lock pin.
The clip body has a lock pin insertion hole in the center.
A vehicle inner side part has the 2nd groove | channel extended in the direction orthogonal to a CSA longitudinal direction through the said center part.

(6) In the CSA attachment device according to (1) above, both side surfaces in the CSA longitudinal direction of the vehicle inner side portion are tapered surfaces that are inclined in a direction that becomes narrower as the distance between the both side surfaces increases away from the seat portion. Yes.

(7) In the CSA attachment device of (1), the CSA attachment device further includes a lock pin.
The CSA attachment device further includes a rib provided on the surface facing the CSA attachment device of the garnish that covers the CSA attachment device.
The rib contacts the lock pin when the garnish is attached.

  According to the CSA attachment device of (1) above, the CSA attachment device has a head portion and a leg portion, the head portion has a seat portion and a vehicle inner portion, and the vehicle inner portion is orthogonal to the CSA longitudinal direction. Since the direction has a narrow width portion narrower than the seat portion, the CSA can be arranged close to the mounting device axis side. As a result, the width of the A pillar garnish can be narrowed, which helps to improve the field of view.

  According to the CSA attachment device of (2) above, the narrow portion and the seat portion are connected by the connecting portion, and the width of the connecting portion in the direction orthogonal to the CSA longitudinal direction approaches the seat portion from the narrow width portion. Since it has expanded, a force (F3 in FIG. 5) having a component that pushes the CSA side end of the seat portion and the connecting portion in the vicinity thereof toward the inner panel works during CSA deployment, and the CSA mounting device immediately after the start of CSA deployment It is advantageous for suppressing the inclination of the.

  According to the CSA attachment device of (3) above, the vehicle inner side portion has the first groove extending in the direction parallel to the longitudinal direction of the CSA through the center portion of the clip body. The lock pin insertion jig can be positioned by entering the first groove, and the first groove becomes a positioning groove in the direction perpendicular to the first groove of the lock pin insertion jig. As a result, the space for inserting the peripheral wall of the lock pin insertion jig, which is conventionally provided outside the both side surfaces in the direction perpendicular to the longitudinal direction of the CSA, on the vehicle inner side of the CSA mounting device becomes unnecessary, and the CSA is further narrowed. It can be brought close to or brought into contact with the width portion, and the width of the A pillar garnish can be further reduced.

  According to the CSA attachment device of (4) above, since the rib extending across the first groove is provided, the rigidity of the vehicle inner side in the direction orthogonal to the CSA longitudinal direction is increased. As a result, it is possible to ensure strength and rigidity in a direction orthogonal to the CSA longitudinal direction of the clip main body head, although the narrow width portion and the first groove are provided in the vehicle inner side portion.

  According to the CSA attachment device of the above (5), the vehicle inner side portion has the second groove extending in the direction perpendicular to the CSA longitudinal direction through the center portion of the clip body. It can be used as a groove for inserting a lock pin removal tool.

  According to the CSA attachment device of (6) above, both side surfaces in the CSA longitudinal direction of the vehicle inner side portion are tapered surfaces that are inclined in a direction that becomes narrower as the distance between the both side surfaces increases away from the seat portion. Therefore, the lock pin can be reliably inserted into the CSA attachment device while the lock pin insertion jig is positioned in the CSA longitudinal direction with respect to the CSA attachment device in accordance with both tapered surfaces.

  According to the CSA attachment device of the above (7), the rib facing the lock pin at the time of garnish attachment and pushing the lock pin is provided on the surface facing the CSA attachment device of the garnish, so it was temporarily fixed to the CSA attachment device. The lock pin can be permanently fixed by being pushed into the clip body when the garnish is attached. As a result, the lock pin can be automatically inserted in the garnish attachment, and the lock pin insertion process can be reduced as compared with the conventional case. Also, if the lock pin is in a floating state during insertion, the garnish will also be in a floating state, so it can be visually judged whether the lock pin is floating or fully inserted, and incompletely mounting the lock pin Can be eliminated.

It is the side view seen in the CSA longitudinal direction of the CSA attachment apparatus of one Example of this invention. FIG. 2 is a front view of the CSA attachment device of FIG. 1 as viewed in a direction orthogonal to the CSA longitudinal direction. FIG. 3 is an enlarged plan view of the CSA attachment device of FIG. 2. FIG. 3 is a perspective view of the CSA attachment device of FIG. 2. It is the side view (CSA is displayed with a cross section) seen in the CSA longitudinal direction of the CSA attachment apparatus of FIG. 1 and its vicinity. It is a perspective view of the CSA attachment device of FIG. 1 and a lock pin insertion jig. It is a perspective view of a conventional CSA attachment device and a lock pin insertion jig. FIG. 2 is a cross-sectional view of the CSA attachment device of FIG. 1 and the A pillar and A pillar garnish as viewed in the CSA longitudinal direction (however, the CSA attachment device is shown in a side view). It is sectional drawing (however, a CSA attachment clip is shown with a side view) which looked at the CSA longitudinal direction of the conventional CSA attachment clip and A pillar and A pillar garnish.

A CSA attachment device 10 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 6 and 8.
In the figure, FR indicates the front of the vehicle in the front-rear direction, IN indicates the inner side of the vehicle in the left-right direction, L indicates the CSA longitudinal direction when the CSA is housed between the A pillar body member and the A pillar garnish, The direction orthogonal to the longitudinal direction L is shown.

The CSA attachment device 10 is a clip for attaching the CSA 12 to the vehicle body member 11 at the tab 12b portion. FIG. 8 shows a case where the CSA 12 includes a main body 12a and a tab 12b, and the main body 12a is rolled.
The body member 11 is, for example, an A pillar, and includes an inner panel 11a, an outer panel 11b, and a reinforcement 11c. Hereinafter, the case where the body member to which the CSA 12 is attached is the inner panel 11a of the A pillar 11 will be described as an example. In FIG. 8, 14 is a windshield, and 15 and 16 are weather strips.

The CSA attachment device 10 includes a resin clip body 20 and a resin or metal lock pin 40.
The clip body 20 has a head portion 21 and a leg portion 22. The clip body 20 sandwiches the tab 12b of the CSA 12 and the holding plate 18 between the head 21 and the inner panel 11a, and positions the head 21 on the vehicle inner side (A pillar garnish 13 side) from the inner panel 11a. The leg 22 is attached to the inner panel 11a in a state where the leg 22 is inserted through the hole of the inner panel 11a. At this time, the lock pin 40 is in the temporary fixing position P <b> 1 (shown in FIG. 1), and the tip of the lock pin is above the locking claw 22 a of the leg portion 22 in the drawing. In this state, the locking claw 22a can be elastically displaced toward the leg axis, and the locking claw 22a can pass through the hole in the inner panel 11a.

  Thereafter, when the A pillar garnish 13 is attached, the lock pin 40 is pushed into the clip body 20 to the fixing position P2 (illustrated in FIG. 1) by the rib 70 (illustrated in FIG. 8) formed on the back surface of the A pillar garnish 13. As a result, the latch 22a of the leg 22 cannot be elastically displaced toward the leg axis, and the clip body 20 cannot be removed from the hole of the inner panel 11a.

The CSA 12 is housed in a space between the A pillar garnish 13 and the inner panel 11a in a folded state. The outer shape of the cross section of the main body 12a of the CSA 12 is substantially circular as shown in FIG.
The CSA body 12 a is located on the opposite side (vehicle rear side) of the head 21 of the clip body 20 from the windshield 14, and extends along the CSA longitudinal direction L.

  At the time of a vehicle collision, an inflation gas is supplied from an inflator (not shown), the CSA 12 expands and expands, and the expansion pressure pushes the A pillar garnish 13 away from the inner panel 11a. The CSA 12 expands and expands from the space formed between the A pillar garnish 13 and the inner panel 11a into the vehicle interior and between the occupant and the door, thereby restraining the occupant from the door side. In FIG. 8, 13 ′ shows a state where the A pillar garnish 13 is expanded, and 12 ′ shows a part of the expanded and expanded state of the CSA 12.

As shown in FIGS. 1 to 5, the head portion 21 of the clip main body 20 includes a seat portion 23 parallel to the clip mounting surface 17 (FIG. 5) of the inner panel 11 a, and the seat portion 23 in the opposite direction to the leg portion 22. It has the vehicle inner side part 24 (parts other than the seat part 23 among the head parts 21) extended.
The vehicle inner side portion 24 has a narrow width portion 24a whose width is narrower than the seat portion 23 and a connecting portion 24b for connecting the narrow width portion 24a and the seat portion 23 in a direction P orthogonal to the CSA longitudinal direction.

The width of the narrow portion 24a in the direction P perpendicular to the CSA longitudinal direction may be constant or substantially constant, or may increase as the seat portion 23 is approached.
The width of the connecting portion 24b in the direction P perpendicular to the CSA longitudinal direction increases as the seat portion 23 is approached.

The width a in the direction P perpendicular to the CSA longitudinal direction at the end of the narrow width portion 24a on the side away from the seat 23 is 0. 0 of the width b in the direction P perpendicular to the CSA longitudinal direction of the seat 23. 8 times or less. That is, a ≦ 0.8b.
The width b of the seat portion 23 in the direction P orthogonal to the CSA longitudinal direction is the same as or substantially the same as the width of the conventional clip.

The reason for a ≦ 0.8b is to clearly reduce the width of the vehicle inner side portion 24 that requires space saving other than the seat portion 23 with respect to the seat portion 23. When a ≦ 0.8b, the outer shape of the cross section of the CSA 12 can be brought close to the axis 20a of the clip body 20, and the width of the A pillar garnish 13 is clearly narrowed.
The reason why the width b of the seat 23 is the same as or almost the same as the width of the conventional clip is that when the seat width b is reduced, when the CSA is deployed with a force F2 (FIG. 5) from the side, or When the CSA attachment device 10 is pulled with a force F1 (FIG. 5) through the tab 12b attaching the CSA body 12, the end A of the seat 23 (the end on the side far from the CSA 12) A moment is applied at the fulcrum, and the reaction force applied to the claw 22a increases at the CSA 12 side portion B (FIG. 5) of the peripheral edge of the clip insertion hole of the inner panel 11a. This is because it becomes easy to suppress it to the conventional level.

  The clip body 20 has a lock pin insertion hole 25 extending in the axial direction at the center. The lock pin 40 is inserted into the lock pin insertion hole 25. The axis 20a of the clip main body 20 matches the axis of the lock pin insertion hole 25.

The vehicle inner side portion 24 has a first groove 26 that extends in the direction parallel to the CSA longitudinal direction L through the center portion of the clip body 20.
The vehicle inner portion 24 crosses the first groove 26 in a direction orthogonal to the first groove 26 on both sides of the center portion (lock pin insertion hole 25) of the clip body 20 in a direction parallel to the CSA longitudinal direction L. It has a rib 27 extending.
Of the first groove 26, the first portion 26 a on the side farther from the central portion (lock pin insertion hole 25) of the clip body 20 than the rib 27 is an end of the vehicle inner side portion 24 in the CSA longitudinal direction L. It extends to the side surface 29 and is open at the end side surface 29. The depth of the first portion 26a of the first groove 26 is equal to or substantially equal to the height of the narrow width portion 24a.
As will be described later (FIG. 6), the first portion 26a of the first groove 26 has a lock pin insertion jig when the CSA attachment device 10 is attached to the A pillar inner panel 11a using the lock pin insertion jig 80. 80 is used to receive the rib 83 and align the lock pin insertion jig 80 and the CSA attachment device 10 in a direction P perpendicular to the longitudinal direction of the CSA.

  A portion (second portion) 26 b closer to the center of the clip body 20 than the rib 27 in the first groove 26 is open to the lock pin insertion hole 25. The depth of the second portion 26 b of the first groove 26 is equal to or substantially equal to the sum of the depth of the first portion 26 a of the first groove 26 and the thickness of the head 41 of the lock pin 40. . The head portion 41 of the lock pin 40 has a first head portion 41 a that enters into the second portion 26 b of the first groove 26. When the lock pin 40 is inserted to the fixed position P2, the lower surface of the first head portion 41a of the head 41 of the lock pin 40 is in contact with the bottom surface 26c (FIG. 4) of the second portion 26b of the first groove 26. Abuts vertically.

The vehicle inner side part 24 has the 2nd groove | channel 28 extended in the direction P orthogonal to a CSA longitudinal direction through the said center part of the clip main body 20. FIG. The second groove 28 extends in the direction P perpendicular to the CSA longitudinal direction from the center portion of the clip body 20 to the side surface 30 parallel to the CSA longitudinal direction L of the vehicle inner side portion 24 and is open at the side surface 30. . The depth of the second groove 28 is the sum of the depth of the first portion 26 a of the first groove 26 and the thickness of the head 41 of the lock pin 40, that is, the second portion 26 b of the first groove 26. Is equal to or approximately equal to the depth of
When the lock pin 40 is inserted to the fixed position P2, the lower side surface 42 (FIG. 1) of the second portion 41b of the head 41 of the lock pin 40 comes into contact with the bottom surface 28a of the second groove 28 in the vertical direction.

  The end of the lower surface 42 of the second portion 41b of the head 41 of the lock pin 40 is an inclined surface 42a that is inclined obliquely upward in a direction approaching the head end. When it is necessary to remove the lock pin 40 from the clip body 20 during maintenance, a jig (a screwdriver with a minus tip or its equivalent) is inserted between the inclined surface 42a and the groove bottom surface 28a in FIG. Thus, the lock pin 40 can be removed by applying an upward load to the lock pin 40 and moving it upward. At this time, the second groove 28 can be used for driver insertion.

  Both side surfaces 29 in the CSA longitudinal direction L of the vehicle inner side portion 24 are tapered surfaces that are inclined in a direction in which the distance between the both side surfaces 29 decreases as the distance from the seat portion 23 increases. As shown in FIG. 6, both side surfaces 29 formed of a tapered surface are formed between the lock pin insertion jig 80 and the CSA when the CSA attachment device 10 is attached to the inner panel 11 a of the A pillar using the lock pin insertion jig 80. This is a mating surface for aligning the mounting device 10 with the CSA longitudinal direction L. In this case, the lock pin insertion jig 80 has a pair of guide walls 81, and the opposing surfaces 82 of the guide walls 81 are aligned with both side surfaces 29 of the CSA attachment device 10.

  A rib 83 protruding in the CSA longitudinal direction L is formed on the facing surface 82 of the guide wall 81. The rib 83 is a direction perpendicular to the longitudinal direction of the CSA when the CSA attachment device 10 is attached to the inner panel 11a of the A pillar using the lock pin insertion jig 80. It becomes a mating surface to be aligned with P. That is, when the CSA attachment device 10 is attached to the inner panel 11a of the A pillar, the rib 83 is inserted into the first portion 26a of the first groove 26 of the CSA attachment device 10, and the lock pin insertion jig 80 and the CSA attachment are attached. The apparatus 10 is positioned in a direction P perpendicular to the CSA longitudinal direction.

  FIG. 5 shows a state in which the CSA attachment device 10 is attached to the inner panel 11 a of the A pillar using the lock pin jig 80. In this state, the CSA 12 is attached to the inner panel 11a by sandwiching the tab 12b and the pressing plate 18 between the CSA attachment device 10 and the inner panel 11a. The lock pin 40 is in the temporary fixing position P1.

  In order to permanently fix the CSA attachment device 10 and the CSA 12 to the inner panel 11a, the lock pin 40 must be pushed to the position P2 in FIG. In the present invention, when the A pillar garnish 13 that covers the CSA 12 is attached to the inner panel 11a of the A pillar at a part different from the CSA attachment device 10, the push of the lock pin 40 to the position P2 is performed on the A pillar garnish 13. It is performed simultaneously with the attachment to the inner panel 11a.

  For this purpose, as shown in FIG. 8, ribs 70 that come into contact with the lock pin 40 when the garnish is attached are formed on the CSA attachment device facing surface of the A pillar garnish 13 (the back surface of the A pillar garnish 13). The height of the rib 70 is set to such a height that the lower surface 42 of the lock pin 40 pushed in by the rib 70 is seated on the groove bottom surfaces 28a and 26c when the A pillar garnish 13 is attached at a normal position. .

Next, the operation of the CSA attachment device 10 according to the embodiment of the present invention will be described.
The CSA 12 is attached to the inner panel 11a by the CSA attachment device 10. At that time, the lock pin 40 is inserted into the clip body 20 using the lock pin insertion jig 80 and temporarily fixed. At this time, the lock pin 40 is in the temporary fixing position P1.
Instead of inserting the lock pin 40 into the clip body 20 when attaching the CSA attachment device 10 to the inner panel 11a, a lock pin insertion jig 80 is used in advance before attaching the CSA attachment device 10 to the inner panel 11a. Then, the lock pin 40 may be inserted into the clip body 20. Also in this case, the lock pin 40 is in the temporary fixing position P1.

  Thereafter, the A pillar garnish 13 is attached to the inner panel 11a with a garnish attachment device (for example, a tether clip, not shown) at a portion different from the CSA attachment device 10 portion, and the CSA 12 and the CSA attachment device 10 are attached to the A pillar garnish. Cover with 13. When the A pillar garnish 13 is mounted, the lock pin 40 is pushed from the temporary fixing position P1 to the fixing position P2 by the rib 70 formed on the back surface of the A pillar garnish 13, and the CSA attachment device 10 is permanently fixed to the inner panel 11a.

  At the time of a side collision of the vehicle, a CSA expansion gas is supplied from an inflator (not shown), the CSA 12 expands and expands, and the A pillar garnish 13 is pushed from the inner panel 11a to the vehicle compartment side. In FIG. 8, 12 'shows a part of the expanded and expanded CSA 12, and 13' shows a state in which the A pillar garnish 13 is detached from the inner panel 11a. The CSA 12 'expands into the passenger compartment through the space between the A pillar garnish 13' and the inner panel 11a, and restrains the occupant from the side.

Next, effects of the CSA attachment device 10 according to the embodiment of the present invention will be described.
First, the clip body 20 of the CSA attachment device 10 has a head portion 21 and a leg portion 22, the head portion 21 has a seat portion 23 and a vehicle inner side portion 24, and the vehicle inner side portion 24 is orthogonal to the CSA longitudinal direction. Since the narrow width portion 24a is narrower than the seat portion 23 (having a width a not more than 0.8 times the width b of the seat portion 23) in the direction P, the cross-sectional outer shape of the CSA body 12a is represented by It can be arranged close to the lead 20a side. As a result, the width of the A pillar garnish 13 can be reduced, which is useful for improving the field of view. In this case, the amount of shift is equal to or more than {1/2 · (b−a) + the thickness of the peripheral wall 104a of the lock pin insertion jig 104 of the prior art (FIG. 9)}. This is because the thickness of the peripheral wall 104a out of the amount that can be shifted is not present in the present invention.

  Further, since the width b of the seat portion 23 is secured as before (the width of the clip head 107 in FIG. 9 in the P direction), the assembled state of the CSA mounting device 10 to the A pillar 11 and the CSA when the CSA is deployed. Inclination of the attachment device 10, removal of the locking claw 22a of the CSA attachment device 10 (detachment of the locking claw 22a from the inner panel hole), removal of the seat portion of the tab 12b of the CSA 12 (insertion of the leg portion 22 provided on the tab 12b) The phenomenon that the hole expands when the tab 12b is pulled and passes through the seat portion 23) can be suppressed.

More specifically, in FIG. 5, when the tab 12b is pulled in the F1 direction, the point A contacts the surface of the tab 12b and the point B contacts the back of the body hole. Although the pawl 22a is easy to come off, the width b of the seat portion 23 is as large as before, so that the locking pawl 22a can be prevented from coming off.
When the force of F2 is applied to the CSA mounting device 10 in the initial stage of CSA deployment, it is advantageous that the width b of the seat portion 23 is wider (point B) since the force is received at point B with point A as a fulcrum in FIG. Is less powerful).

  Further, the narrow portion 24a and the seat portion 23 are connected by the connecting portion 24b, and the width of the connecting portion 24b in the direction P perpendicular to the longitudinal direction of the CSA increases as the seat portion 23 approaches the narrow portion 24a. Therefore, both side surfaces of the connecting portion 24 b are curved and expand as the seat portion 23 is approached. As a result, when the CSA 12 is deployed, a component force F3 (FIG. 5) in the direction in which the seat 23 is pressed against the body member (inner panel 11a) acts on the CSA side end of the seat 23 and in the vicinity thereof. This is advantageous for suppressing the inclination of the device 10 and for preventing the locking claw 22a from coming off.

  Since the vehicle inner side portion 24 of the CSA attachment device 10 has a first groove 26 extending in a direction parallel to the CSA longitudinal direction L through the lock pin insertion hole 25 at the center of the clip body, the first of the first grooves 26 is provided. The portion 26 a serves as a positioning groove for positioning the lock pin insertion jig 80 in a direction orthogonal to the first groove 26. As a result, the peripheral wall 104a of the lock pin insertion jig 104 provided on the outside of both side surfaces in the direction P perpendicular to the CSA longitudinal direction in the vehicle inner portion of the CSA attachment device (FIGS. 7 and 9). An insertion space (a space larger than the thickness of the wall 104a) is unnecessary in the present invention. Therefore, in the present invention, the CSA 12 can be brought closer to the narrow portion 24a or brought into contact with the outer surface of the narrow portion 24a, and the width of the A pillar garnish 13 can be further narrowed.

  Since the vehicle inner side portion 24 of the CSA attachment device 10 is provided with the rib 27 extending across the first groove 26, the rigidity of the vehicle inner side portion 24 in the direction P orthogonal to the CSA longitudinal direction is increased. As a result, it is possible to ensure strength and rigidity in the direction P perpendicular to the CSA longitudinal direction of the CSA attachment device 10 despite the provision of the narrow width portion 24a and the first groove 26 in the vehicle inner side portion 24. it can.

  Moreover, since the vehicle inner side part 24 of the CSA attachment apparatus 10 has the 2nd groove | channel 28 extended in the direction P orthogonal to a CSA longitudinal direction through the lock pin insertion hole 25 of clip body center part, the 2nd groove | channel 28 is provided. It can be used as a groove for inserting the lock pin removing tool and a groove for escaping interference with the rib 70 in FIG.

  Further, both side surfaces 29 in the CSA longitudinal direction L of the vehicle inner side portion 24 of the CSA attachment device 10 are tapered surfaces that are inclined in a direction that becomes narrower as the distance between the both side surfaces 29 increases from the seat portion 23. Therefore, in the CSA longitudinal direction L, the pair of guide walls 81 of the lock pin insertion jig 80 are aligned with both tapered surfaces 29 and positioned on the CSA attachment device 10 while the lock pin 40 is positioned on the clip body 20 of the CSA attachment device 10. The lock pin insertion hole 25 can be securely inserted.

  Since a rib 70 is provided on the surface of the A pillar garnish 13 facing the CSA mounting device so that the lock pin 40 is pressed against the lock pin 40 when the garnish is mounted, the lock pin 40 temporarily fixed to the CSA mounting device 10 is attached. In the garnish attachment step, the CSA attachment device 10 can be permanently fixed to the inner panel 11a by being pushed into the clip body 20 simultaneously with the garnish attachment. As a result, the lock pin 40 can be inserted up to the P2 position within the same process as the garnish attachment process, and the lock pin insertion process can be reduced as compared with the conventional case where two processes are required for garnish attachment and lock pin insertion.

  In addition, when the lock pin 40 is in a floating state during insertion in the main fixing, the garnish 13 is also in a floating state. Therefore, whether or not the lock pin 40 is floating is sufficiently determined by observing the attachment state of the garnish 13. It is possible to determine whether or not the lock pin 40 is inserted into the lock pin 40 and to eliminate the floating of the lock pin 40 when the lock pin 40 is fixed.
