Description

[Technical field]

[0001] The present invention relates to a mounting clip and a vehicle curtain airbag device. [Background technology]

[0002] The following Patent Document 1 discloses a mounting clip used to mount an object such as a curtain airbag to a body panel of a vehicle. This mounting clip has a bush (clip body) consisting of a head and a leg, and a lock pin disposed in a lock pin insertion hole formed in the head. The leg of the clip body has a pair of opposing parts (leg pieces) and is inserted into a clip mounting hole formed in the body panel. During this insertion, the pair of leg pieces elastically deform in a direction approaching each other and then elastically return to their original state, and the locking claws formed on the pair of leg pieces engage with the edge of the clip mounting hole. In this state, when the lock pin is pushed into the pair of leg pieces, the pair of leg pieces cannot elastically deform in a direction approaching each other, and removal of the clip body from the clip mounting hole is restricted. In addition, when the lock pin is pushed into the pair of leg pieces, the pair of legs of the lock pin slide against guide surfaces formed on the inner surfaces of the pair of leg pieces, causing the pair of legs to move away from each other, and the side claws formed on the pair of legs engage with the edge of the clip mounting hole. As a result, the removal load applied to the mounting clip from the object to be attached is received by both the clip body and the lock pin, improving the removal resistance.

[0003] [Patent Document 1] Patent No. 6281514 Summary of the Invention [Problem to be solved by the invention]

[0004] The mounting clips of the above configuration are, for example, packed together in a bag for transportation, and therefore the corners of other clips may hit the lock pin due to vibrations and shocks during transportation. As a result, the lock pin may be pushed into one of the pair of legs, and although the probability is low, the lock pin may be erroneously inserted. If the lock pin is erroneously inserted, the pair of legs are restricted from elastically deforming in the direction of approaching each other, so that the locking claws of the pair of legs interfere with the edge of the clip mounting hole, making it impossible to insert the pair of legs into the clip mounting hole.

[0005] In consideration of the above, the present invention aims to provide a mounting clip that allows a pair of leg pieces of the clip body to be inserted into a clip mounting hole even if the lock pin is inserted incorrectly, and a vehicle curtain airbag device equipped with the mounting clip. [Means for solving the problem]

[0006] The mounting clip of the first aspect of the present invention has a head and a pair of leg pieces extending from the head, and a lock pin insertion hole formed in the head that connects between the pair of leg pieces, and a clip body in which the pair of leg pieces are inserted into a clip mounting hole formed in an object to be fixed, with the pair of leg pieces approaching each other during the insertion, and a lock pin that is arranged in the lock pin insertion hole and is pushed toward the pair of leg pieces with the pair of leg pieces inserted into the clip mounting hole, thereby restricting the approach of the pair of leg pieces and preventing the pair of leg pieces from being removed from the clip mounting hole.When the pair of leg pieces are inserted into the clip mounting hole with the lock pin pushed toward the pair of leg pieces, the lock pin slides against an inclined surface formed on the inner surface in the opposing direction of the pair of leg pieces approaching each other, and the lock pin is returned to the opposite side to the direction in which the lock pin is pushed in.

[0007] In a first aspect, the clip body has a head and a pair of legs extending from the head. A lock pin insertion hole communicating between the pair of legs is formed in the head. The pair of legs are inserted into a clip attachment hole formed in the object to be fixed. During this insertion, the pair of legs approach each other. A lock pin is disposed in the lock pin insertion hole formed in the head of the clip body. The lock pin is pushed into the pair of legs with the pair of legs inserted into the clip attachment hole, thereby restricting the pair of legs from approaching each other and preventing the pair of legs from being removed from the clip attachment hole. In this aspect, when the pair of legs are inserted into the clip attachment hole with the lock pin pushed into the pair of legs, the lock pin slides against an inclined surface formed on the inner surface of the pair of legs in the opposing direction that the pair of legs are trying to approach each other. As a result, the lock pin is returned to the opposite side to the pushing direction of the lock pin, so that the restriction of the pair of legs by the lock pin is released and the pair of legs can be inserted into the clip attachment hole.

[0008] A second aspect of the present invention relates to the mounting clip of the first aspect, wherein the inclined surface is a curved surface whose inclination angle with respect to the pushing direction gradually increases toward the pushing direction.

[0009] In the second aspect, since the inclined surfaces formed on the pair of legs of the clip body are curved as described above, when the lock pin is pushed in the pushing direction, the load applied to the lock pin from the inclined surfaces increases gradually, which makes it easier to push in the lock pin.

[0010] In the mounting clip of the third aspect of the present invention, in the first or second aspect, the locking pin has a pair of legs with side claws formed thereon, and when the pair of leg pieces of the clip body are inserted into the clip mounting hole and the locking pin is pushed in the pushing direction, the pair of legs of the locking pin move away from each other and the side claws engage with the edge of the clip mounting hole.

[0011] According to the third aspect, the pair of legs of the clip body are inserted into the clip attachment hole, and the lock pin is pushed in the pushing direction. In this state, the side claws formed on the pair of legs of the lock pin engage with the edge of the clip attachment hole. This allows the removal load applied to the attachment clip to be received by the lock pin as well, improving the removal resistance.

[0012] A vehicle curtain airbag device according to a fourth aspect of the present invention includes a curtain airbag that is stored in an upper part of a side part of the vehicle compartment and that inflates and deploys downwardly of the vehicle when gas is supplied thereto, and a mounting clip described in any one of the first to third aspects, in which the pair of leg pieces of the clip body are inserted into the clip mounting hole formed in a body panel serving as the fixed object provided in the upper part of the side part of the vehicle compartment, and the curtain airbag is engaged with the body panel by the mounting clip body.

[0013] In a fourth aspect, a curtain airbag stored in an upper part of a side part of a vehicle compartment is inflated and deployed downwardly of the vehicle by supplying gas therein. A body panel is provided in the upper part of the side part of the vehicle compartment as an object to be fixed. A pair of legs of a clip body of a mounting clip are inserted into a clip mounting hole formed in the body panel. The curtain airbag is engaged with the body panel by the mounting clip body. The mounting clip described above is one described in any one of the first to third aspects, and therefore the same action and effect as any one of the above aspects can be obtained. Effect of the Invention

[0014] As described above, in the mounting clip and vehicle curtain airbag device according to the present invention, even if the lock pin is erroneously inserted, the pair of leg pieces of the clip body can be inserted into the clip mounting hole. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] A mounting clip 10 and a vehicle curtain airbag device 50 according to one embodiment of the present invention will be described below with reference to Figures 1 to 9. First, the overall configuration of the vehicle curtain airbag device 50 will be described, and then the configuration of the mounting clip 10 will be described.

[0017] (Overall configuration of curtain airbag device) As shown in Fig. 1, a vehicle curtain airbag device 50 is mounted on a sedan-type vehicle V, as an example, and includes a curtain airbag 52 and an inflator (not shown). Note that the arrow UP shown in Fig. 1 and Fig. 2 indicates the upper side of the vehicle, the arrow FR shown in Fig. 1 indicates the front side of the vehicle, and the arrow OUT shown in Fig. 2 indicates the outward side in the vehicle width direction.

[0018] 1, the curtain airbag 52 is folded into a long shape and stored together with an inflator in a roof side portion 56 provided at the upper end of the side portion of the vehicle interior. In this curtain stored state, the long curtain airbag 52 extends from the rear side of the A-pillar 58 along the roof side rail 60 to the upper end side of the C-pillar (not shown). In FIG. 1, 62 denotes an A-pillar garnish and 64 denotes a roof head lining.

[0019] The curtain airbag 52 is formed in a bag shape from, for example, a nylon or polyester cloth material. A plurality of tongue-shaped tabs 54 are provided on the upper edge of the curtain airbag 52 in a line in the front-rear direction of the vehicle. The plurality of tabs 54 extend from the upper edge of the curtain airbag 52 toward the upper side of the vehicle. As shown in FIG. 2, a clip insertion hole 55 is formed in each tab 54. A mounting clip 10 according to this embodiment is inserted into the clip insertion hole 55 of each tab 54.

[0020] Each mounting clip 10 is inserted into a clip mounting hole 68 formed in a body panel 66 of the roof side portion 56. In this way, the curtain airbag 52 is fixed to the body panel 66 by using each mounting clip 10. A tension belt 70 is stretched between the front end of the curtain airbag 52 and the A-pillar 58. When gas is supplied to the interior of the curtain airbag 52 from an inflator, the curtain airbag 52 is inflated and deployed toward the vehicle lower side along the side of the passenger compartment as shown by the two-dot chain line in FIG. 1. The body panel 66 corresponds to the "fixed object," and the curtain airbag 52 corresponds to the "mounted object."

[0021] (Mounting clip configuration) As shown in Fig. 3 to Fig. 7, the mounting clip 10 includes a clip body 12 and a lock pin 24. The clip body 12 and the lock pin 24 are made of flexible resin, such as polyacetal or polyhexamethylene adipamide. In the following description, the directions indicated by the arrows X, Y, Z, and Z1 in each figure are referred to as the facing direction X, the arrangement direction Y, the insertion / removal direction Z, and the pushing direction Z1, respectively. The facing direction X, the arrangement direction Y, and the insertion / removal direction Z are mutually perpendicular. The pushing direction Z1 is one side of the insertion / removal directions Z.

[0022] The clip body 12 has an elongated shape with the insertion / removal direction Z as its longitudinal direction. The clip body 12 integrally has a head 14 and a pair of leg pieces 16. The head 14 has a generally rectangular parallelepiped shape with the arrangement direction Y as its longitudinal direction. A lock pin insertion hole 18 is formed in the head 14, penetrating the head 14 in the insertion / removal direction Z. The lock pin insertion hole 18 has a generally rectangular shape when viewed from the insertion / removal direction Z. Furthermore, temporary fastening holes 20 are formed in the wall portions of the head 14 on both sides in the opposing direction X through the lock pin insertion hole 18.

[0023] The pair of leg pieces 16 are generally plate-shaped with a thickness direction in the facing direction X and a longitudinal direction in the insertion / removal direction Z, and extend from the head 14 in the pushing-in direction Z1. The pair of leg pieces 16 face each other with a gap in between in the facing direction X, and a gap 22 communicating with the lock pin insertion hole 18 is formed between the pair of leg pieces 16. At the tip side (the push-in direction Z1 side) of the pair of leg pieces 16, a locking claw 16A is formed on each of the outer surfaces of the pair of leg pieces 16 in the facing direction X. The pair of leg pieces 16 are expanded in thickness in the facing direction X at the tip side where each locking claw 16A is formed.

[0024] As shown in FIG. 2, the pair of leg pieces 16 of the clip body 12 are inserted into the clip insertion hole 55 formed in the tab 54 of the curtain airbag 52, and are inserted into the clip mounting hole 68 formed in the body panel 66 from the vehicle inner side (the left side in FIG. 2). When the pair of leg pieces 16 are inserted (inserted) into the clip mounting hole 68, the locking claws 16A of the pair of leg pieces 16 slide against the edge of the clip mounting hole 68. As a result, the pair of leg pieces 16 are elastically deformed toward the side where they approach each other, that is, toward the inside in the facing direction X. Then, when the locking claws 16A of the pair of leg pieces 16 pass through the clip mounting hole 68, the pair of leg pieces 16 elastically return to their original state, and the locking claws 16A of the pair of leg pieces 16 engage with the edge of the clip mounting hole 68 from the vehicle outer side (the right side in FIG. 2). As a result, the clip body 12 is configured to be locked to the body panel 66.

[0025] In the above-mentioned locked state, the tab 54 is disposed between the head 14 of the clip body 12 and the body panel 66, and the head 14 prevents the tab 54 from falling off the clip body 12. A spacer (not shown) is disposed between the tab 54 and the body panel 66. This spacer is formed, for example, from a flexible resin in a generally wave washer shape.

[0026] The lock pin 24 is disposed in the lock pin insertion hole 18 of the clip body 12. The lock pin 24 has a pair of legs 26 arranged side by side in the arrangement direction Y, and a connecting portion 28 (see FIG. 7) connecting the legs 26. The pair of legs 26 are elongated in the insertion / removal direction Z. The tip portions of the pair of legs 26 (end portions on the pushing-in direction Z1 side) are disposed between the pair of leg pieces 16. The tip portions of the pair of legs 26 are formed with side claws 26A that protrude outward in the arrangement direction Y.

[0027] The connecting portion 28 has an inverted U-shape with an open end opposite the push-in direction Z1 when viewed from the facing direction X, and connects one longitudinal end (end opposite the push-in direction Z1) of the pair of legs 26 in the arrangement direction Y. The connecting portion 28 is flexible, and the pair of legs 26 can be moved and separated from each other. The lock pin 24 has anti-pullout claws (not shown) on both sides of the connecting portion 28 in the facing direction X. These anti-pullout claws fit into the temporary fastening holes 20 of the clip body 12, so that the lock pin 24 is temporarily fastened at the temporary fastening position shown in FIGS. 3 and 4.

[0028] With the lock pin 24 in the temporary fixing position, the pair of leg pieces 16 of the clip body 12 are elastically deformable toward each other, i.e., toward the inside in the opposing direction X, and the pair of leg pieces 16 can be inserted into and removed from the clip mounting hole 68 of the body panel 66. For this reason, the operation of fixing the tab 54 of the curtain airbag 52 to the body panel 66 by the clip body 12, i.e., the operation of inserting the pair of leg pieces 16 of the clip body 12 into the clip mounting hole 68, is performed with the lock pin 24 in the temporary fixing position.

[0029] After the pair of leg pieces 16 of the clip body 12 are inserted into the clip attachment hole 68, the lock pin 24 is pushed toward the pair of leg pieces 16 (pushing direction Z1). This pushing is performed, for example, by using a dedicated tool. During this pushing, the anti-pullout claw of the lock pin 24 elastically deforms and comes out of the temporary fastening hole 20 of the clip body 12. When the lock pin 24 is pushed to the pushing complete position shown in Figures 5 and 6, the pushing of the lock pin 24 is completed.

[0030] When the lock pin 24 is pushed in to the fully pushed-in position, the pair of legs 26 are sandwiched between the pair of leg pieces 16, and the pair of leg pieces 16 cannot elastically deform in a direction approaching each other. This keeps the locking claws 16A of the pair of leg pieces 16 engaged with the edge of the clip attachment hole 68 from the outside of the vehicle, and restricts (prevents) the clip body 12 from being removed from the clip attachment hole 68.

[0031] As shown in FIG. 7, a pair of guide surfaces 30 are formed in the arrangement direction Y on the inner surfaces of the pair of leg pieces 16 of the clip body 12 in the facing direction X. The pair of guide surfaces 30 are formed on the tip side of the pair of leg pieces 16, and are inclined so as to move away from each other toward the pushing direction Z1. While the lock pin 24 is being pushed from the temporary fixing position to the pushing-completed position, the tips of the pair of legs 26 slide against the pair of guide surfaces 30, so that the pair of legs 26 move away from each other. When the lock pin 24 is pushed to the pushing-completed position, as shown in FIG. 5, the side claws 26A of the pair of legs 26 protrude outward in the arrangement direction Y from the pair of leg pieces 16. These side claws 26A engage with the edge of the clip mounting hole 68 from the vehicle outer side (the right side in FIG. 2). This is configured so that the removal load applied to the mounting clip 10 when the curtain airbag 52 is deployed is received by both the clip body 12 and the lock pin 24. In addition, FIG. 7 illustrates a state in which, of the clip body 12 and the lock pin 24, only the clip body 12 is cut off.

[0032] 8, inclined surfaces 32 are formed on the inner surfaces of the pair of leg pieces 16 of the clip body 12 in the opposing direction X. These inclined surfaces 32 are formed in the middle of the pair of leg pieces 16 in the insertion / removal direction Z, and are inclined so as to approach inward in the opposing direction X as they approach the pushing-in direction Z1. These inclined surfaces 32 are formed in a curved shape in which the inclination angle with respect to the pushing-in direction Z1 gradually increases as they approach the pushing-in direction.

[0033] In the mounting clip 10 in which the inclined surfaces 32 are formed on the pair of leg pieces 16 of the clip body 12, when the pair of leg pieces 16 are inserted into the clip mounting hole 68 in a state in which the lock pin 24 is erroneously pushed toward the pair of leg pieces 16 (incorrect insertion state; incorrect pushing state), the inclined surfaces 32 formed on the pair of leg pieces 16 and the tip of the lock pin 24 slide against each other. That is, when the pair of leg pieces 16 are inserted into the clip mounting hole 68, the locking claws 16A formed on the outer surfaces of the pair of leg pieces 16 in the facing direction X slide against the edge of the clip mounting hole 68, and the pair of leg pieces 16 are elastically deformed in a direction in which they approach each other. As a result, the inclined surfaces 32 formed on the pair of leg pieces 16 try to approach each other (see arrow A in FIG. 9). As a result, the tip corners of the pair of legs 26 of the lock pin 24 slide against the inclined surfaces 32, and a component force acts on the lock pin 24 in the direction opposite to the pushing direction Z1. This component force causes the lock pin 24 to return in the opposite direction to the pushing direction Z1 (see arrow R in FIG. 9).

[0034] (Action and Effects) Next, the operation and effects of this embodiment will be described.

[0035] In the vehicle curtain airbag device 50 according to this embodiment, the curtain airbag 52 stored in the roof side portion 56 of the vehicle V receives gas from an inflator to inflate and deploy downwardly of the vehicle. A body panel 66 provided on the roof side portion 56 is formed with a plurality of clip mounting holes 68, into which the clip bodies 12 of the mounting clips 10 are inserted. The curtain airbag 52 is fastened to the body panel 66 by the clip bodies 12.

[0036] The clip body 12 has a head 14 and a pair of leg pieces 16 extending from the head 14. A lock pin insertion hole 18 is formed in the head 14, communicating between the pair of leg pieces 16. The pair of leg pieces 16 are inserted into the clip attachment hole 68. During this insertion, the pair of leg pieces 16 approach each other. A lock pin 24 is disposed in the lock pin insertion hole 18 formed in the head of the clip body 12. The lock pin 24 is pressed toward the pair of leg pieces 16 with the pair of leg pieces 16 inserted into the clip attachment hole 68, thereby restricting the approach of the pair of leg pieces 16 and preventing the pair of leg pieces 16 from being removed from the clip attachment hole 68.

[0037] In this embodiment, when the pair of legs 16 are inserted into the clip mounting hole 68 with the lock pin 24 pressed toward the pair of legs 16, the locking claws 16A of the pair of legs 16 slide against the edge of the clip mounting hole 68, and the pair of legs 16 try to elastically deform in a direction approaching each other (see arrow A in FIG. 9). As a result, a component force acts on the tip corner of the lock pin 24 in the opposite direction to the pushing-in direction Z1 from the inclined surface 32 formed on the inner surface of the pair of legs 16 in the facing direction X, and the lock pin 24 is automatically returned to the opposite side (see arrow R in FIG. 9). In this way, the lock pin 24 is returned to the opposite direction to the pushing-in direction Z1, so that the elastic deformation of the pair of legs 16 in the approaching direction is permitted, and the locking claws 16A of the pair of legs 16 can pass through the clip mounting hole 68, and the pair of legs 16 can be inserted into the clip mounting hole 68.

[0038] The above effects will be further explained using a comparative example 100 shown in Figs. 10 to 14. This comparative example 100 is a mounting clip for a curtain airbag like the mounting clip 10 according to this embodiment, but the configurations of the clip body 102 and the lock pin 110 are different from the configurations of the clip body 12 and the lock pin 24 according to this embodiment. Note that in Figs. 10 to 14, the same reference numerals are used in the comparative example 100 to designate components that are basically the same as those in the mounting clip 10. Hereinafter, the comparative example 100 will be referred to as the mounting clip 100.

[0039] The clip body 102 has a head 14 and legs 104 extending from the head 14, and has a lock pin insertion hole 106 that opens on the side opposite to the pushing direction Z1. On the insertion direction Z1 side of the head 14, the lock pin insertion hole 106 is divided into a pair of lock pin insertion chambers 106A by a backup rib 108. The pair of lock pin insertion chambers 106A are aligned in the opposing direction X. Elastically deformable locking claws 104A are formed on the walls of the legs 104 on both sides of the opposing direction X. When the legs 104 are inserted into the clip mounting hole 68, the locking claws 104A slide against the edge of the clip mounting hole 68 and elastically deform in a direction approaching each other. When the locking claws 104A pass through the clip mounting hole 68, the locking claws 104A elastically return to their original state and engage with the edge of the clip mounting hole 68 from the side opposite to the head 14.

[0040] The lock pin 110 has an elongated shape with the insertion / removal direction Z as its longitudinal direction, and is disposed in the lock pin insertion hole 106. The lock pin 110 has a pair of legs 112 connected by a connecting part (not shown). The pair of legs 112 face each other in the opposing direction X. When the lock pin 110 is pushed into the push-in completion position shown in FIG. 12, the pair of legs 112 enter the pair of lock pin insertion chambers 106A and engage with the locking claws 104A from the inside in the opposing direction X. This prevents the locking claws 104A from elastically deforming in the direction approaching each other, and restricts the clip body 102 from being removed from the clip attachment hole 68. When the lock pin 110 is pushed into the push-in completion position, the pair of anti-removal claws 116 of the lock pin 110 fit into the pair of anti-removal holes 114 formed in the clip body 102. When a force is applied to the lock pin 110, which is located in the fully pushed-in position, in the direction opposite to the pushing direction Z1, a pair of anti-slip claws 116 get caught on the edges of a pair of anti-slip holes 114, thereby restricting the displacement of the lock pin 110 in the opposite direction.

[0041] The above-mentioned mounting clips 100 are transported in a bag, for example, in the order of several hundred pieces. Due to vibrations and shocks during the transport, the corners of the heads 14 of other mounting clips 100 may hit the lock pins 110, as shown in FIG. 14. As a result, the lock pins 110 are pushed toward the leg parts 104, and although the probability is low, it is considered that the lock pins 110 may be erroneously inserted. When the lock pins 110 are erroneously inserted, the elastic deformation of the locking claws 104A in the direction of approaching each other is restricted, so that the locking claws 104A interfere with the edge of the clip mounting hole 68, making it impossible to insert the leg parts 104 into the clip mounting hole 68. In addition, when the lock pins 110 are erroneously inserted, the elastically deformed state of the fall-out prevention claws 116 continues for a long time, as shown in FIG. 14, and the fall-out prevention claws 116 undergo creep deformation. As a result, if a large force acts on the mounting clip 100 when the curtain airbag 52 is deployed, the prevention of the lock pin 110 by the fall-out prevention claw 116 may be inadvertently released, decreasing the holding force of the mounting clip 100 on the curtain airbag 52. For this reason, with the above-mentioned mounting clip 100, it becomes necessary to perform an inspection to determine whether the lock pin 110 has been inserted incorrectly before the mounting clip 100 is attached to the body panel 66.

[0042] In contrast, in this embodiment, even if the lock pin 24 is erroneously inserted, when the pair of leg pieces 16 are inserted into the clip mounting hole 68, the lock pin 24 is automatically returned to the opposite side from the pushing direction Z1, making it possible to insert the pair of leg pieces 16 into the clip mounting hole 68. This solves the problems with the mounting clip 100.

[0043] In this embodiment, the inclined surfaces 32 formed on the pair of leg pieces 16 of the clip body 12 are curved surfaces whose inclination angle with respect to the pushing direction Z1 gradually increases as the lock pin 24 approaches the pushing direction Z1. Therefore, when the lock pin 24 is pushed in the pushing direction Z1, the load applied to the lock pin 24 from the inclined surfaces 32 gradually increases. This allows the lock pin 24 to be pushed in smoothly.

[0044] Furthermore, in this embodiment, the lock pin 24 has a pair of legs 26 on which side claws 26A are formed, and when the lock pin 24 is pushed in the pushing direction Z1 with the pair of legs 16 inserted into the clip mounting hole 68, the pair of legs 26 move away from each other and the side claws 26A engage with the edge of the clip mounting hole 68. As a result, the removal load applied to the mounting clip 10 is also received by the lock pin 24, improving the removal resistance.

[0045] In the above embodiment, the inclined surfaces 32 formed on the pair of legs 16 of the clip body 12 are curved surfaces, but the present invention is not limited to this. The inclined surfaces may be flat surfaces.

[0046] In the above embodiment, the lock pin 24 has a pair of legs 26, and the side claws 26A are formed on the pair of legs 26, but the present invention is not limited to this. The configuration of the lock pin can be changed as appropriate. As described above, when the lock pin 24 is inserted into the clip mounting hole 68 while being pushed toward the pair of legs 16, the locking claws 16A of the pair of legs 16 slide against the edge of the clip mounting hole 68, and the pair of legs 16 try to plastically deform in a direction in which they approach each other (see arrow A in FIG. 9). As a result, a component force acts on the tip corner of the lock pin 24 in the opposite direction to the pushing direction Z1 from the inclined surface 32 formed on the inner surface of the pair of legs 16 in the facing direction X, and the lock pin 24 is automatically returned to the opposite direction to the pushing direction Z1. At this time, it is preferable to configure the lock pin 24 to return to the opposite side from the initial position (initial return position) to which it automatically returns. For example, by making the anti-pullout claws of the lock pin 24 more easily deformable, the lock pin can be configured to return to a predetermined amount (e.g., 3 mm) more than the automatic return position of the lock pin in the embodiment, and the plate thickness of the pair of leg pieces 16 can be increased, thereby improving strength.

[0047] In the above embodiment, the present invention is applied to the mounting clip 10 that fixes the curtain airbag 52 to the body panel 66, but the present invention is not limited to this. The clip according to the present invention can be used as a fastener that fixes a vehicle part, which is an attachment target, to a fixing target such as a vehicle body panel.

[0048] In addition, the present invention can be implemented in various modifications without departing from the spirit and scope of the present invention. Furthermore, the scope of the present invention is not limited to the above-described embodiment. [Explanation of symbols]
