The seventh aspect is applicable to the first embodiment of the present invention described later.

  According to the first aspect, the center position of the garnish hole is offset to the vehicle front side with respect to the center axis of the clip mounting hole. As a result, the width in the pillar longitudinal direction of the bridge portion of the pillar garnish (the distance between the vehicle front end surface and the vehicle rear end surface of the bridge portion) is set such that the center position of the garnish hole is offset from the center axis of the clip mounting hole. The width of the bridge portion in the absence is increased. Therefore, the cross-sectional area of the bridge portion in the longitudinal direction of the pillar is increased, the strength is increased, and the flow of molten metal in the bridge portion is improved during molding, so that a weld (molding defect) is formed in the bridge portion during molding. Can be suppressed. As a result, when a load from the anchor of the tether clip is applied to the edge of the garnish hole during CSA deployment, the pillar garnish can be prevented from breaking from the bridge portion or the vicinity thereof.

  According to the second aspect, the center of the connection position of the at least one engagement holding portion and the tether to the seat portion is in a direction along the plane including the tether longitudinal direction and on the front side of the vehicle from the center axis of the leg. It is offset. Further, the vehicle front side end surface of the engagement holding portion is in contact with the vehicle front side inner surface of the garnish hole. Of the rear end surface of the engagement holding portion and the rear end surface of the tether seat connection portion, the one on the rear side of the vehicle is in contact with the rear inner surface of the garnish hole. That is, the connection portion to the seat portion of the combination of the engagement holding portion and the tether is fitted in the garnish hole without play in the direction along the surface including the tether longitudinal direction. Therefore, the width of the bridge portion in the pillar longitudinal direction is increased. As a result, the cross-sectional area in the pillar longitudinal direction of the bridge portion increases to increase the strength, and it is possible to suppress the hot water flow in the bridge portion during molding and the formation of strong welds in the bridge portion. Moreover, when the load from the anchor of the tether clip is applied to the edge of the garnish hole when the CSA is deployed, the pillar garnish can be prevented from breaking from the bridge portion or the vicinity thereof.

  According to the third aspect, since the tether stands up from the seat portion and is bent to the front side of the vehicle and then bent to the rear side of the vehicle, the length of the tether can be increased, and the pillar and the pillar garnish can be extended when the CSA is deployed. The interval for CSA deployment formed between the two can be increased. In addition, since the front end of the tether and the front end of the garnish hole are at the same position in the longitudinal direction of the pillar garnish, the tether is prevented from interfering with the front end of the garnish hole during CSA deployment, and smooth extension of the tether is not hindered. It is also advantageous in terms of space.

  According to the 4th aspect, since the meat stealing recessed part is formed in the bridge part, it can suppress that a sink mark and a void are formed in a bridge part at the time of shaping | molding of a pillar garnish. Therefore, when the load from the anchor of the tether clip is applied to the edge of the garnish hole during CSA deployment, the pillar garnish can be prevented from breaking from the bridge portion or the vicinity thereof.

  In the fifth aspect, a pair of the engagement holding portions are provided with a connection portion to the seat portion of the tether. The pair of engagement holding portions hold the edge portions at both ends of the garnish hole, which is advantageous in suppressing wobbling of the pillar garnish with respect to the tether clip.

  In the sixth aspect, one engagement holding portion is provided on the vehicle front side of the connection portion to the seat portion of the tether. Since the connection part to the seat part of the tether is on the rear side of the vehicle from the engagement holding part, the tether length is increased when the tether is bent from the connection part to the seat part to the front side of the vehicle and then bent to the rear side of the vehicle. be able to. As a result, the interval for CSA expansion formed between the pillars and the pillar garnish during CSA expansion can be increased.

  According to the 7th aspect, the center of a pair of engagement holding | maintenance part is offset to the side away from an anchor along the surface containing a tether longitudinal direction rather than the center axis line of a leg. Therefore, when the pillar garnish is assembled to the pillar using this tether clip, the width of the bridge portion of the pillar garnish in the pillar longitudinal direction can be increased. As a result, the strength of the bridge portion is increased, and it is possible to suppress the formation of welds in the bridge portion due to an improved flow of hot water in the bridge portion during molding. Therefore, when the load from the anchor of the tether clip is applied to the edge of the garnish hole during CSA deployment, the pillar garnish can be prevented from breaking from the bridge portion or the vicinity thereof.

<< First Example >>
A pillar garnish mounting structure 2 according to a first embodiment of the present invention and a tether clip 10 according to a first embodiment of the present invention used in the pillar garnish mounting structure 2 will be described with reference to FIGS. The main part of the tether clip 10 and the pillar garnish attachment structure 2 are the same. The first embodiment is a case where there are a pair of engagement holding portions 40. 3 and 5-8, the left side of the figure is the front side of the vehicle, and the right side of the figure is the rear side of the vehicle. In some of the drawings, “FR” indicates the front side of the vehicle and “UP” indicates the upper side of the vehicle.

  The pillar garnish mounting structure 2 includes a resin-made tether clip 10 having flexibility, a pillar garnish 70 made of resin harder than the tether clip 10, and a metal-made, for example, steel pillar (front pillar of a vehicle) 90. And comprising. The flexible resin material constituting the tether clip 10 is, for example, polyhexamethylene adipamide. However, other resin materials may be used as long as they are flexible and have a necessary strength.

  The tether clip 10 has a tether 20 described later and an anchor 50 provided at the tip thereof. Between the pillar garnish 70 and the pillar 90, a curtain airbag (not shown, hereinafter also referred to as CSA. CSA is an abbreviation for Curtain Shield Airbag) is disposed. When the vehicle collides or rolls over, the CSA expands and deploys in a short time, and the pillar garnish 70 moves away from the pillar 90 in response to the load from the CSA. At this time, the tether 20 extends until the pillar garnish 70 hits the anchor 50, and a gap is formed between the pillar garnish 70 and the pillar 90 where CSA can expand and deploy. Further, the tether clip 10 stops the pillar garnish 70 from moving in a direction away from the pillar 90 more than the state in which the pillar garnish 70 hits the anchor 50, and prevents the pillar garnish 70 from scattering in the vehicle compartment direction.

  The pillar garnish 70 and the pillar 90 have a longitudinal direction and are directed in the same direction. The tether 20 of the tether clip 10 has a tether longitudinal direction L. The tether longitudinal direction L is oriented in the same direction as the longitudinal direction of the pillar garnish 70 and the pillar 90. The tether 20 is bent along a plane including the tether longitudinal direction L.

  The tether clip 10 includes a seat portion 12, at least one engagement holding portion 40 connected to one surface of the seat portion 12, and a tether longitudinal direction L connected to the one surface of the seat portion 12 and directed in the pillar garnish longitudinal direction. The tether 20 is bent along a surface including the tether longitudinal direction L, the anchor 50 is connected to the tip of the tether 20 on the vehicle rear side, and is connected to the other surface of the seat portion 12. And the wobbling-suppressing elastic piece 60 provided on the seating surface facing the pillar 90 of the seat portion 12. A locking claw 16 is provided on the leg 14 so as to be elastically accessible and away from the clip center axis 10a. The engagement holding part 40 has a rising part 42 rising from the seat part 12 and a bulging part 44 connected to the rising part 42 and bulging in a direction perpendicular to the rising direction of the rising part 42. The engagement holding part 40 is formed in a hollow shape, and the bulging part 44 is elastically deformable in the bulging direction of the bulging part 44.

The pillar garnish 70 has a tether storage portion 72 formed integrally with the pillar garnish 70 on the back. The tether storage portion 72 has a rectangular bottom wall 74 and a side wall 76 connected to three sides of the bottom wall 74. The side wall 76 is connected to three sides, two sides extending in the longitudinal direction of the pillar garnish of the bottom wall 74 and one side of the bottom wall 74 on the front side in the vehicle front-rear direction. A side wall 76 is not provided on one side of the bottom wall 74 on the rear side in the vehicle front-rear direction, and the tether storage portion 72 has a tether storage portion opening 78 that opens toward the rear side of the vehicle. The anchor 50 integrally connected to the tip of the tether 20 extending in the tether longitudinal direction L protrudes outside the tether storage portion 72 through the tether storage portion opening 78 when the tether clip 10 is assembled to the pillar garnish 70. This ensures a tether length in a limited space. As a result, a tether length that can form a sufficient gap between the pillar garnish 70 and the pillar 90 during the CSA deployment is secured.

  The bottom wall 74 has a rectangular garnish hole 80, and the extending direction of the major axis of the garnish hole 80 is directed to the longitudinal direction of the pillar garnish 70 (same as the tether longitudinal direction L). The vehicle rear side of the garnish hole 80 is blocked by a bridge portion 74 a that extends in the direction perpendicular to the longitudinal direction of the pillar garnish 70 over the extension of the long side of the garnish hole 80. The bridge portion 74 a forms a part of the bottom wall 74. The inner surface of the bridge portion 74a may be offset outward with respect to the inner surface of the bottom wall 74 (the surface facing the inner side of the tether storage portion 72), as in the illustrated example.

  The pillar 90 has a clip mounting hole 92. The pillar garnish 70 is attached to the pillar 90 at the portion of the clip attachment hole 92 using the tether clip 10. When the pillar garnish 70 is attached to the pillar 90, the tether 20 of the tether clip 10 is inserted through the garnish hole 80 of the pillar garnish 70, and the leg 14 of the tether clip 10 is inserted into the clip attachment hole 92 of the pillar 90. ing. In a state in which the pillar garnish 70 is attached to the pillar 90 using the tether clip 10, the edge of the garnish hole 80 of the pillar garnish 70 has the bulging portion 44 and the seat portion 12 of the engagement holding portion 40 of the tether clip 10. The edge of the clip mounting hole 92 of the pillar 90 is sandwiched between the wobbling prevention elastic piece 60 and the locking claw 16 of the tether clip 10.

  In a state where the pillar garnish 70 is attached to the pillar 90, the center position in the longitudinal direction of the garnish hole 80 is offset to the vehicle front side with respect to the center axis of the clip attachment hole 92 (same as the clip center axis 10a).

  In the tether clip 10 as a component of the pillar garnish mounting structure 2 (also in the tether clip 10 alone), the connection position of the at least one engagement holding part 40 and the tether 20 to the seat part 12 Is offset from the center axis of the leg 14 (same as the clip center axis 10a) in the direction along the plane including the tether longitudinal direction L and away from the anchor 50 (same as the front side of the vehicle).

  The vehicle front side end surface of at least one engagement holding portion 40 is in contact with the vehicle front side inner surface of the garnish hole 80 (the inner surface of the front short side of the garnish hole 80). Of the vehicle rear side end surface of the at least one engagement holding portion 40 and the vehicle rear side end surface of the connection portion to the seat portion 12 of the tether 20, the one on the vehicle rear side is the vehicle rear side inner surface of the garnish hole 80 ( The inner surface of the rear short side of the garnish hole 80).

  The width W in the direction along the plane including the pillar garnish longitudinal direction of the bridge portion 74a of the pillar garnish 70 due to the offset of the center position in the longitudinal direction of the garnish hole 80 from the center axis of the clip mounting hole 92 is the width of the garnish hole 180. The center position is larger than the width in the direction along the plane including the pillar garnish longitudinal direction of the bridge 174a in the pillar garnish mounting structure 102 of the comparative example which is not offset with respect to the center axis of the clip mounting hole 192.

  The tether 20 rises from the seat portion 12 and is bent once toward the vehicle front side (side away from the anchor 50) and then bent toward the vehicle rear side (anchor side). It is desirable that the front end of the tether 20 and the front end of the garnish hole 80 are at the same position in the pillar ganish longitudinal direction.

The bridge portion 74a of the bottom wall 74 of the tether storage portion 72 may be formed with a meat stealing recess 74b. However, the concave portion 74b is a portion that does not obstruct the hot water flow of the bridge portion 74a, for example, the central portion of the bridge portion 74a in the direction in which the short side of the garnish hole 80 extends, and the portion that is difficult to reduce the strength of the bridge portion 74a For example, it is desirable that the bridge portion 74a be provided near the garnish hole 80 in the vicinity of the outer surface (lower side surface).

  When the tether clip 10 is viewed as a single unit, the tether clip 10 further has the following structure.

  As shown in FIGS. 8 to 10, the tether 20 includes a root portion 22 connected to the seat portion 12, a tip portion 26 connected to the anchor 50, and an intermediate portion extending between the root portion 22 and the tip portion 26. 24. The tether 20 has a tether longitudinal direction L extending along one surface orthogonal to the seat portion 22, and at least a part of the entire length of the tether 20 is curved along the one surface.

The shape of the tether cross section seen at a surface perpendicular to the tangential direction of the tether 20 at an arbitrary tether portion separated from the seat portion 12 along the shape of the tether 20 is an elongated cross section.
Further, the shape of the tether cross section at the root portion 22 and the intermediate portion 24 is wider and thinner than the shape of the tether cross section at the distal end portion 26. However, the shape of the tether cross section at the distal end portion 26 is equal to or substantially equal to the shape of the tether cross section (in the total length of the tether) of the clip 110 of the comparative example.

  The length of the long side of the tether cross section in the root portion 22 and the intermediate portion 24 is longer than the length of the short side of the garnish hole 80. For this reason, if the direction in which the major axis of the tether cross section extends in the direction in which the minor axis of the garnish hole 80 extends, the tether 20 cannot be disposed in the garnish hole 80 when the tether clip 10 is assembled to the pillar garnish 70.

  In order to arrange the tether 20 in the garnish hole 80, the extending direction of the long axis of the elongated section in the root portion 22 and the intermediate portion 24 is a direction orthogonal to the long axis of the garnish hole 80 (the short axis of the garnish hole 80 extends). From the direction) by a predetermined angle (an angle in the range of 40 degrees ± 20 degrees). Accordingly, the tether 20 is twisted around the center of the cross section of the tether 20. The tether 20 is curved in a direction parallel to a plane along which the tether 20 extends, and is twisted around the center of the cross section of the tether 20. That is, the tether 20 has bending and twisting. On the other hand, the tether 120 of the clip 110 of the comparative example is not twisted around the center of the cross section of the tether 120. That is, the tether 120 of the clip 110 of the comparative example is only bent.

  As shown in FIG. 1 to FIG. 3, at least a part of the root part 22 and the intermediate part 24 is gently curved along the tether 20, and other parts (a part near the seat part 12 of the root part 22 and The intermediate portion 24 may extend linearly at a portion close to the distal end portion 26.

  In the free state of the tether 20 where no load is applied to the tether 20, the tether 20 is connected to the root portion 22 and the intermediate portion 24 from the connecting portion to the root portion 22 to the intermediate portion 24a farthest from the anchor 50. The first ridge line 28a on the side far from the anchor 50 and the second ridge line 28b on the side close to the anchor 50 are provided at the ends of the major axis in the extending direction of the first ridge line 28a and the second ridge line 28b. The perspective relationship from the anchor 50 is maintained over the entire length of the first ridge line 28a and the second ridge line 28b and is not reversed.

From the intermediate portion 24a farthest from the anchor 50 of the intermediate portion 24 to the connection portion of the tether 20 to the distal end portion 26 of the intermediate portion 24, the long axis of the tether cross section extends in the extending direction end, The third ridge line 28c and the fourth ridge line 28d on the side close to the seat portion 12 are provided, and the perspective relationship between the third ridge line 28c and the fourth ridge line 28d from the seat portion 12 is the third ridge line 28c. And maintained over the entire length of the fourth ridgeline 28d and not reversed.

  The first ridge line 28a and the third ridge line 28c are connected smoothly (without a step), and the second ridge line 28b and the fourth ridge line 28d are connected smoothly (without a step).

  The sum of the length of the first ridge line 28a and the length of the third ridge line 28c is close to the sum of the length of the second ridge line 28b and the length of the fourth ridge line 28d, and is equal to or substantially equal to each other. In the tether 20, an upper curved portion that curves upwardly (in a direction away from the seat portion 12) is formed in a portion of the intermediate portion 24 near the base portion 22, and then the tip portion 26 of the intermediate portion 24. A downward curved portion that is curved in a convex shape toward the lower portion (in the direction approaching the extended surface of the seat portion 12) is formed in the portion on the side closer to the head. The outer peripheral edge portion of the upper bending portion is connected to the inner peripheral edge portion of the lower bending portion, and the inner peripheral edge portion of the upper bending portion is connected to the outer peripheral edge portion of the upper bending portion. Thereby, the sum of the length of the first ridge line 28a and the length of the third ridge line 28c is equal to or substantially equal to the sum of the length of the second ridge line 28b and the length of the fourth ridge line 28d.

  The length of the long side of the tether cross section at the tip portion 26 of the tether 20 is shorter than the length of the short side of the garnish hole 80. As a result, the tether clip 10 can be assembled to the pillar garnish 70. In assembly, the longitudinal direction of the anchor 50 is directed in the extending direction of the long axis of the garnish hole 80, the anchor 50 is inserted through the garnish hole 80, the anchor 50 is inserted into the tether storage portion 72, and the tip portion 26 of the tether 20 is moved. It is located in the garnish hole 80. In this state, the distal end portion 26 of the tether 20 can rotate around the axis of the distal end portion 26 in the garnish hole 80, so the anchor 50 is rotated 90 degrees. Next, the tether 20 is inserted into the tether storage portion 72, and the assembly is completed in a state where the edge portion of the garnish hole 80 is held between the bulging portion 44 of the engagement holding portion 40 and the seat portion 12. In this state, the anchor 50 protrudes from the tether storage portion opening 78 to the outside of the tether storage portion 72.

  A pair of guide plates 38 projecting in a direction perpendicular to a direction parallel to the extending direction of the anchor 50 (longitudinal direction of the anchor 50) is provided at the end of the intermediate portion 24 of the tether 20 on the tether tip portion 26 side. ing. The pair of guide plates 38 are provided substantially symmetrically with the intermediate portion 24 of the tether 20 interposed therebetween.

  The anchor 50 includes an anchor main body 52 extending in a direction perpendicular to the tether longitudinal direction L and parallel to the seat portion 12, and a pair of anchor elastic pieces extending between the anchor main body 52 and the tether distal end portion 26 in both side spaces of the tether distal end portion 26. 54. The anchor body 52 extends in the anchor longitudinal direction, and the anchor elastic piece 54 extends in a direction orthogonal to the anchor longitudinal direction. The anchor elastic piece 54 extends along the same plane as the guide plate 38 of the tether 20. The anchor elastic piece 54 and the guide plate 38 are separated from each other but are opposed to each other.

  The wobbling prevention elastic piece (hereinafter simply referred to as “elastic piece”) 60 is formed by inserting the leg 14 of the tether clip 10 into the clip mounting hole 92 of the pillar 90 and attaching the tether clip 10 to the pillar 90. The edge of the clip mounting hole 92 is elastically sandwiched between the locking claw 16 of the leg 14 and the elastic piece 60 to suppress wobbling of the tether clip 10 with respect to the pillar 90.

The elastic piece 60 is integrally connected to the seat 12 at a portion of the seat facing the pillar 90 to which the tether clip 10 is attached, away from the clip center axis 10a. The elastic piece 60 is linear or curved in a free state of the elastic piece 60 from a connecting portion to the seat portion 12 toward a grounding point to the pillar 90 at a position facing the connecting portion in the clip axial direction. It has the axial direction part 62 extended in this direction. The illustrated example shows a case where the axial direction portion 62 is linear, but the linear shape may be curved as long as the ground contact point to the pillar 90 is not different from the linear case.

  The direction in which the elastic piece 60 wants to suppress the wobbling of the tether clip 10 with respect to the pillar 90 is the rotation in the direction along the plane perpendicular to the tether longitudinal direction L in particular. In order to suppress the wobbling of the tether clip 10 in the direction in which the wobble is desired to be suppressed, the elastic pieces 60 are arranged on both sides of the surface including the tether longitudinal direction L with the surface including the tether longitudinal direction L in between, and the tether longitudinal direction It is arranged at a distance from the plane including L in the direction perpendicular to the plane.

  The elastic piece 60 is bent from the axial direction portion 62 when viewed in a direction orthogonal to the surface including the tether longitudinal direction at the distal end portion of the axial direction portion 62 opposite to the connection portion to the seat portion 12. It has a bent portion 64 that extends in parallel with the seat portion 12 in a free state. The bent portion 64 is bent from the axial portion 62 toward the center of the clip in a free state of the elastic piece 60. However, the elastic piece 60 does not have a bent part, and the lower end part may be left as an axial part.

  The seat 12 is formed in a rectangular shape in a direction along a plane orthogonal to the clip center axis 10a. The elastic pieces 60 are arranged at the four corners of the rectangular seating surface.

The leg 14 is connected to a seat surface opposite to the seat surface to which the tether 20 of the seat portion 12 is connected, and extends in a direction away from the seat portion 12 on the opposite side of the tether 20. The pair of locking claws 16 are coupled to the leg 14 at a coupling portion at one end of the locking claw 16 and are separated from the leg 14 by an inverted U-shaped slit except for the coupling portion. As a result, the locking claw 16 can swing in the direction of approaching and moving away from the clip center axis 10a around the coupling portion. A claw operation portion 18 extending in a direction orthogonal to the clip center axis 10a and extending away from the clip center axis 10a is provided at the distal end of the locking claw 16.
The above structure is applicable to both the first and second embodiments of the present invention.

The first embodiment of the present invention further has the following structure.
The tether clip 10 according to the first embodiment has a pair of engagement holding portions 40 as shown in FIGS. A connection portion of the tether 20 to the seat portion 12 is located between the two engagement holding portions 40.

  The center of the connection position of the engagement holding portion 40 and the tether 20 to the seat portion 12 is the center between the outer end surfaces in the tether longitudinal direction L of the two engagement holding portions 40 as shown in FIGS. Match. In this case, when the two engagement holding portions 40 are fitted into the garnish holes 80, the outer end surface on the vehicle front side and the outer end surface on the vehicle rear side in the tether longitudinal direction L of the two engagement holding portions 40 correspond to the garnish holes 80. The short side on the vehicle front side and the short side on the vehicle rear side are in contact with each other.

  Next, operations and effects of the pillar garnish mounting structure 2 and the tether clip 10 according to the first embodiment of the present invention will be described.

  First, the positional relationship between the garnish hole 80 and the clip mounting hole 92 is as follows. The center position of the garnish hole 80 is offset to the vehicle front side with respect to the center axis of the clip mounting hole 92. Further, the width of the bridge portion 74a of the pillar garnish 70 in the pillar axis direction is such that the center position of the garnish hole is not offset with respect to the center axis of the clip attachment hole as in the pillar garnish attachment structure 102 of the comparative example. It is larger than the width of the bridge portion. Therefore, the cross-sectional area of the bridge portion 74a in the pillar longitudinal direction is increased, the strength is increased, and the hot water flow of the bridge portion 74a is improved at the time of molding, so that formation of welds in the bridge portion 74a can be suppressed. Therefore, when the load from the anchor 50 of the tether clip 10 is applied during CSA deployment, the pillar garnish 70 can be prevented from breaking from the bridge portion 74a or the vicinity thereof.

  The positional relationship between the center of the connection position of the engagement holding portion 40 and the tether 20 in the tether clip 10 to the seat portion 12 and the position of the leg 14 is as follows. However, the center of the connection position of the engagement holding part 40 and the tether 20 to the seat part 12 is the center point between the outer surfaces of the engagement holding part 40 when there are two engagement holding parts. The center of the connection position of the engagement holding portion 40 and the tether 20 to the seat portion 12 is in a direction along the plane including the tether longitudinal direction L and the anchor, rather than the center axis of the leg 14 (same as the clip center axis 10a). Offset to the side away from 50. Therefore, the width W in the pillar longitudinal direction of the bridge portion 74a of the pillar garnish 70 is increased. As a result, the cross-sectional area and strength of the bridge portion 74a in the pillar longitudinal direction are increased, and the hot water flow of the bridge portion 74a is improved at the time of molding, thereby suppressing the formation of strong welds in the bridge portion 74a. Further, when a load from the anchor 50 of the tether clip 10 is applied during CSA deployment, the pillar garnish 70 can be prevented from breaking from the bridge portion 74a or the vicinity thereof.

  When the front end 24a of the tether 20 and the front end of the garnish hole 80 are in the same position in the longitudinal direction of the pillar garnish, smooth extension of the tether 20 is not hindered during CSA deployment, and space is advantageous. If the length of the garnish hole 80 is short and the front end of the garnish hole 80 is located behind the front end 24a of the tether, the tether 20 interferes with the inner surface of the bottom wall 74 of the tether storage portion 72 during CSA deployment, The smooth deployment of the tether 20 is hindered. If the length of the garnish hole 80 is long and the front end of the garnish hole 80 is on the front side of the front end 24a of the tether, the tether storage portion 72 must be extended to the front side of the vehicle, which is disadvantageous in terms of space.

  In the case where the meat stealing recess 74b is formed in the bridge portion 74a, it is possible to suppress the formation of sink marks or voids in the bridge portion 74a during molding. Therefore, it is possible to suppress the pillar garnish 70 from being broken from the bridge portion 74a or the vicinity thereof by a load from the anchor 50 of the tether clip 10 at the time of CSA deployment.

  In the tether clip 10, the center of the connection position of the engagement holding part 40 and the tether 20 to the seat part 12 is offset from the center axis of the leg 14 to the side away from the anchor 50 along the plane including the tether longitudinal direction. Has been. Therefore, when the pillar garnish 70 is assembled to the pillar 90 using the tether clip 10, the width W in the pillar longitudinal direction of the bridge portion 74a of the pillar garnish 70 is automatically set from the width of the bridge portion of the clip of the comparative example. Can increase. As a result, the cross-sectional area and strength of the bridge portion 74a in the longitudinal direction of the pillar are increased, and it is possible to suppress the hot water flow of the bridge portion 74a during molding and the formation of welds in the bridge portion 74a. Therefore, when the load from the anchor 50 of the tether clip 10 is applied during CSA deployment, the pillar garnish 70 can be prevented from breaking from the bridge portion 74a or the vicinity thereof.

<< Second Example >>
Next, a pillar garnish mounting structure 2 and a tether clip 10 used therefor according to a second embodiment of the present invention will be described with reference to FIG. 2nd Example is a case where only one engagement holding | maintenance part 40 is provided. Hereinafter, only portions of the second embodiment different from the first embodiment will be described.

First, regarding the structure, at least one engagement holding portion 40 is composed of a single engagement holding portion arranged on the vehicle front side (the side far from the anchor 50) of the connection portion to the seat portion 12 of the tether 20.
The center of the connection portion of the engagement holding portion 40 and the tether 20 to the seat portion 12 coincides with the center between the vehicle front side end surface of the engagement holding portion 40 and the vehicle rear side end surface of the root portion 22 of the tether 20. .
In that case, when the base part 22 of one engagement holding part 40 and one tether 20 is fitted into the garnish hole 80, the one engagement holding part 40 and the base part 22 of one tether 20 in the tether longitudinal direction L The outer end surface is in contact with the short side of the garnish hole 80.
After rising from the seat portion 12, the tether 20 is once bent toward the vehicle front side and then bent toward the vehicle rear side to reach the anchor 50. In the tether longitudinal direction L, the front end of the tether 20 is at the same position as the front end of the engagement holding portion 40. The front end of the tether 20 corresponds to the intermediate portion 24 a farthest from the anchor 50.

  Next, regarding the operation and effect, since the connecting portion of the tether 20 to the seat portion 12 is on the rear side of the vehicle from the engagement holding portion 40, the tether 20 is once bent from the connecting portion to the seat portion 12 to the front side of the vehicle. When bent to the rear side of the vehicle, the length of the tether 20 can be made longer than when the tether 20 rises from between the pair of engagement holding portions 40 as in the first embodiment. As a result, the CSA deployment interval formed between the pillar 90 and the pillar garnish 70 can be increased during CSA deployment.
