Description

The present invention relates to a mounting clip and a vehicle curtain airbag device.

The following Patent Document 1 discloses a mounting clip used to mount an object such as a curtain airbag to a vehicle body panel. 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 legs of the clip body have a pair of opposing parts (leg pieces) and are inserted into a clip mounting hole formed in the body panel. During this insertion, the pair of legs elastically deform in a direction toward each other and then elastically return to their original state, and the locking claws formed on the pair of legs engage with the edge of the clip mounting hole. In this state, when the lock pin is pushed into the pair of legs, the pair of legs cannot elastically deform in a direction toward 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 legs, the pair of legs of the lock pin slide against guide surfaces formed on the inner surfaces of the pair of legs, 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. This allows the removal load applied to the mounting clip from the object to be received by both the clip body and the lock pin, improving removal resistance.

Patent No. 6281514

For example, mounting clips with the above configuration are shipped in large numbers in a bag, and so vibrations and shocks during shipping can cause the corners of other clips to hit the locking pin. As a result, the locking pin can be pushed into one of the pair of legs, and although there is a low probability of the locking pin being erroneously inserted. When the locking pin is erroneously inserted, the pair of legs are restricted from elastically deforming in the direction of approaching each other, causing the locking claws of the pair of legs to interfere with the edge of the clip mounting hole, making it impossible to insert the pair of legs into the clip mounting hole.

In consideration of the above, the present invention aims to provide a mounting clip that allows a pair of legs of the clip body to be inserted into a clip mounting hole even if the lock pin is erroneously inserted, and a vehicle curtain airbag device that includes the mounting clip.

The mounting clip according to the first aspect of the present invention has a head and a pair of legs extending from the head, a lock pin insertion hole formed in the head that communicates between the pair of legs, a clip body in which the pair of legs are inserted into a clip mounting hole formed in an object to be fixed and the pair of legs approach each other during the insertion, and a lock pin that is disposed in the lock pin insertion hole and is pushed into the pair of legs with the pair of legs inserted into the clip mounting hole, thereby restricting the approach of the pair of legs and preventing the pair of legs from being removed from the clip mounting hole. When the pair of legs are inserted into the clip mounting 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 are approaching each other, and the lock pin is returned to the opposite side to the pushing direction of the lock pin.

In the first aspect, the clip body has a head and a pair of legs extending from the head. A lock pin insertion hole is formed in the head, which communicates between the pair of legs. 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 the inclined surfaces formed on the inner surfaces of the pair of legs in the opposing directions. As a result, the lock pin is returned to the opposite side to the pushing direction of the lock pin, and the restriction of the pair of legs by the lock pin on the approach of the pair of legs is released, and the pair of legs can be inserted into the clip attachment hole.

The second aspect of the present invention relates to a mounting clip according to the first aspect, in which the inclined surface is a curved surface whose inclination angle with respect to the pushing direction gradually increases the closer it is to the pushing direction.

In the second aspect, because the inclined surfaces formed on the pair of legs of the clip body are curved as described above, the load applied to the locking pin from the inclined surfaces increases gradually when the locking pin is pushed in the pushing direction. This allows the locking pin to be pushed in smoothly.

In the mounting clip according to the third aspect of the present invention, in the first or second aspect, the lock pin has a pair of legs with side claws formed thereon, and when the pair of legs of the clip body are inserted into the clip mounting hole and the lock pin is pushed in the pushing direction, the pair of legs of the lock pin are separated from each other and the side claws engage with the edge of the clip mounting hole.

According to the third aspect, a pair of legs of the clip body are inserted into the clip mounting 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 mounting hole. This allows the removal load applied to the mounting clip to be received by the lock pin as well, improving the removal resistance.

The vehicle curtain airbag device according to the fourth aspect of the present invention includes a curtain airbag that is stored in the upper part of the vehicle compartment side and that inflates and deploys downwardly of the vehicle when gas is supplied to the inside of the curtain airbag, and a mounting clip according to any one of the first to third aspects, in which the pair of legs 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 vehicle compartment side, and the curtain airbag is secured to the body panel by the mounting clip body.

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

As described above, with the mounting clip and vehicle curtain airbag device of the present invention, even if the lock pin is erroneously inserted, the pair of legs of the clip body can be inserted into the clip mounting hole.

FIG.

Below, a mounting clip 10 and a vehicle curtain airbag device 50 according to one embodiment of the present invention will be described 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.

(Overall configuration of the 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 direction in the vehicle width direction.

Normally, the curtain airbag 52 is folded into a long shape as shown by the dashed line in FIG. 1 and stored together with the inflator in the roof side section 56 provided at the upper end of the side of the vehicle compartment. 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 is an A-pillar garnish and 64 is a roof head lining.

The curtain airbag 52 is formed into a bag shape using, for example, a nylon or polyester fabric material. A number of tongue-shaped tabs 54 are arranged in the front-to-rear direction of the vehicle on the upper edge of the curtain airbag 52. The 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.

Each mounting clip 10 is inserted into a clip mounting hole 68 formed in the body panel 66 of the roof side portion 56. As a result, the curtain airbag 52 is fixed to the body panel 66 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 the inflator, the curtain airbag 52 inflates and deploys downward 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 "attached object."

(Mounting clip configuration)
As shown in Figures 3 to 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 arrows X, Y, Z, and Z1, which are appropriately indicated in each figure, are referred to as the opposing direction X, the arranging direction Y, the insertion/removal direction Z, and the pushing direction Z1, respectively. The opposing direction X, the arranging direction Y, and the insertion/removal direction Z are mutually perpendicular. The pushing direction Z1 is one side of the insertion/removal directions Z.

The clip body 12 is elongated in the insertion/removal direction Z. The clip body 12 has a head 14 and a pair of legs 16 formed integrally. The head 14 is generally rectangular in shape with the arrangement direction Y as its longitudinal direction. The head 14 is formed with a lock pin insertion hole 18 that penetrates the head 14 in the insertion/removal direction Z. The lock pin insertion hole 18 is generally rectangular when viewed from the insertion/removal direction Z. In addition, the head 14 has temporary fastening holes 20 formed in the walls on both sides of the head 14 in the opposing direction X through the lock pin insertion hole 18.

The pair of leg pieces 16 are generally plate-shaped with the thickness direction being the facing direction X and the longitudinal direction being the insertion/removal direction Z, and extend from the head 14 in the pushing 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 that communicates with the lock pin insertion hole 18 is formed between the pair of leg pieces 16. At the tip side (pushing 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 thickness of the pair of leg pieces 16 in the facing direction X is expanded at the tip side where each locking claw 16A is formed.

As shown in FIG. 2, the pair of legs 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 inside of the vehicle (the left side in FIG. 2). When the pair of legs 16 are inserted (inserted) into the clip mounting hole 68, the locking claws 16A of the pair of legs 16 slide against the edge of the clip mounting hole 68. As a result, the pair of legs 16 are elastically deformed toward the side where they approach each other, that is, toward the inside of the opposing direction X. Then, when the locking claws 16A of the pair of legs 16 pass through the clip mounting hole 68, the pair of legs 16 elastically return, and the locking claws 16A of the pair of legs 16 engage with the edge of the clip mounting hole 68 from the outside of the vehicle (the right side in FIG. 2). This allows the clip body 12 to be locked to the body panel 66.

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 the shape of a roughly wave washer.

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 alignment 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 tips of the pair of legs 26 (the ends on the pushing-in direction Z1 side) are disposed between the pair of leg pieces 16. The tips of the pair of legs 26 are formed with side claws 26A that protrude outward in the alignment direction Y.

The connecting portion 28 has an inverted U-shape with the side opposite the pushing direction Z1 open when viewed from the facing direction X, and connects one longitudinal end of the pair of legs 26 (the end opposite the pushing direction Z1) in the arrangement direction Y. This connecting portion 28 is flexible, and the pair of legs 26 can be moved apart 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, temporarily fastening the lock pin 24 in the temporary fastening position shown in Figures 3 and 4.

When the lock pin 24 is in the temporary fixing position, the pair of legs 16 of the clip body 12 are elastically deformable toward each other, i.e., toward the inside of the opposing direction X, and the pair of legs 16 can be inserted into and removed from the clip attachment hole 68 of the body panel 66. Therefore, 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 legs 16 of the clip body 12 into the clip attachment hole 68, is performed with the lock pin 24 in the temporary fixing position.

After the pair of legs 16 of the clip body 12 are inserted into the clip attachment hole 68, the lock pin 24 is pushed toward the pair of legs 16 (pushing direction Z1). This pushing is performed, for example, using a dedicated tool. During this pushing, the anti-removal 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-completed position shown in Figures 5 and 6, the pushing-in of the lock pin 24 is complete.

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 toward 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.

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 opposing 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, causing the pair of legs 26 to 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 exterior (the right side in FIG. 2). This allows the removal load applied to the mounting clip 10 when the curtain airbag 52 is deployed to be received by both the clip body 12 and the lock pin 24. Note that Figure 7 shows the state in which only the clip body 12 is cut out of the clip body 12 and the lock pin 24.

As shown in FIG. 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 the inside of the opposing direction X as they approach the pushing direction Z1. These inclined surfaces 32 are formed in a curved shape in which the inclination angle with respect to the pushing direction Z1 gradually increases as they approach the pushing direction.

In the mounting clip 10 in which the above-mentioned 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 (misinsertion state; erroneous pushing state), the inclined surfaces 32 formed on the pair of leg pieces 16 and the tip of the lock pin 24 slide. 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 opposing direction X slide against the edge of the clip mounting hole 68, and the pair of leg pieces 16 elastically deform in a direction approaching 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 each inclined surface 32, and a component force acts on the lock pin 24 in the opposite direction 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 Figure 9).

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

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 and inflates downward. 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 body 12 of the mounting clip 10 is inserted. The curtain airbag 52 is secured to the body panel 66 by the clip body 12.

The clip body 12 has a head 14 and a pair of legs 16 extending from the head 14. A lock pin insertion hole 18 is formed in the head 14, which communicates between the pair of legs 16. The pair of legs 16 are inserted into the clip attachment hole 68. During this insertion, the pair of legs 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 pushed toward the pair of legs 16 while the pair of legs 16 are inserted into the clip attachment hole 68, thereby restricting the approach of the pair of legs 16 and restricting removal of the pair of legs 16 from the clip attachment hole 68.

In this embodiment, when the pair of legs 16 are inserted into the clip mounting hole 68 with the lock pin 24 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 attempt 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 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, by returning the lock pin 24 to the opposite side to the pushing direction Z1, elastic deformation of the pair of legs 16 in the approaching direction is permitted, so that 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.

The above effects will be further explained using a comparative example 100 shown in Figures 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 lock pin 110 are different from the configurations of the clip body 12 and lock pin 24 according to this embodiment. Note that in Figures 10 to 14, components in the comparative example 100 that are basically the same as those in the mounting clip 10 are given the same reference numerals. Hereinafter, the comparative example 100 will be referred to as the mounting clip 100.

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 is open 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 lined up in the opposing direction X. Elastically deformable locking claws 104A are formed on the walls on both sides of the opposing direction X of the legs 104. When the legs 104 are inserted into the clip attachment hole 68, the locking claws 104A slide against the edge of the clip attachment hole 68 and elastically deform in a direction approaching each other. When the locking claws 104A pass through the clip attachment hole 68, the locking claws 104A elastically return to their original position and engage with the edge of the clip attachment hole 68 from the side opposite the head 14.

The lock pin 110 is elongated in the insertion/removal direction Z and is disposed in the lock pin insertion hole 106. The lock pin 110 has a pair of legs 112 connected by a connecting portion (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 each of the locking claws 104A from the inside in the opposing direction X. This prevents the locking claws 104A from elastically deforming in the direction of approaching each other, and restricts the removal of the clip body 102 from the clip attachment hole 68. In addition, 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 in the pushed-in position in the opposite direction to the pushing direction Z1, the pair of anti-slip claws 116 hook onto the edges of the pair of anti-slip holes 114, restricting the displacement of the lock pin 110 in the opposite direction.

The above mounting clips 100 are transported in bags, for example, in the order of several hundred pieces. Due to vibrations and shocks during transport, the corners of the heads 14 of other mounting clips 100 may hit the lock pin 110, as shown in FIG. 14. As a result, the lock pin 110 is pushed toward the leg 104, and although there is a low probability, the lock pin 110 may be erroneously inserted. When the lock pin 110 is erroneously inserted, the locking claws 104A are restricted from elastically deforming in the direction in which they approach each other, so that the locking claws 104A interfere with the edge of the clip mounting hole 68, making it impossible to insert the leg 104 into the clip mounting hole 68. In addition, when the lock pin 110 is erroneously inserted, the anti-pullout claws 116 remain elastically deformed for a long time, as shown in FIG. 14, and the anti-pullout 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 retention of the lock pin 110 by the fall-out prevention claw 116 may be inadvertently released, and the retention force of the mounting clip 100 on the curtain airbag 52 may decrease. For this reason, with the above 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.

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

In addition, 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 the closer it is to 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.

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

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

In the above embodiment, the lock pin 24 has a pair of legs 26, and the pair of legs 26 are formed with side claws 26A, but this is not limited to the above. 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 side 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 specified 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 legs 16 can be increased, improving the strength.

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 object, to a fixed object such as a vehicle body panel.

The present invention can be modified in various ways without departing from the spirit of the invention. It goes without saying that the scope of the invention is not limited to the above embodiment.
