Description

  The present invention relates to a clip for a curtain airbag for connecting a pillar garnish in which a curtain airbag is accommodated and an inner panel of a vehicle.

  In recent vehicles (automobiles), in order to ensure the safety of the occupant's head at the time of a collision, a curtain airbag is often attached to the pillar garnish. Various applications have been filed for curtain airbags (see, for example, Patent Document 1).

  As shown in FIG. 1, a curtain airbag 1 (hereinafter simply referred to as “airbag”) is accommodated between an inner panel 2 and a pillar garnish 3 of a vehicle, and the inner panel 2 and the pillar garnish. 3 are connected by a curtain airbag clip 101 (hereinafter simply referred to as “clip”). In a normal case, the clip 101 is attached to a clip attachment seat 111 (dog house) protruding from the pillar garnish 3. When the sensor detects that a load of a predetermined value or more is applied to the side surface of the vehicle, the airbag 1 is instantly inflated by the gas generated by the inflator (gas generator). At this time, the end portion 3 a of the pillar garnish 3 is bent due to the expansion of the airbag 1, and the airbag 1 is deployed from the gap formed between the end portion 3 a and the inner panel 2. In FIG. 1, the pillar garnish 3 when the airbag is deployed is indicated by a one-dot chain line.

The clip 101 needs to be mounted so as to be able to resist the force acting when the pillar garnish 3 is bent. A conventional clip 90 will be described. As shown in FIG. 7A, the conventional clip 90 sandwiches the upper plate portion 94 of the clip mounting seat 93 by a presser plate portion 91 and a flat plate-like pedestal portion 92. For this reason, when the deployment force F of the airbag 1 is applied, the space between the upper plate portions 94 is expanded, the base portion 92 of the clip 90 and the upper plate portion 94 of the clip mounting seat 93 are deformed, and both are separated. There is a risk of it.

The space restricting portion arrangement hole 15 is provided.

  As shown in FIG. 3, the notch 14 of the clip mounting seat 111 according to the present embodiment has an inner width 14 a on the front side (entrance) that is closer to the outlet on the back side (the gap regulating portion arrangement hole 15. The connecting portion is longer than the inner width 14b. That is, the inner width 14 a of the inlet portion of the cut portion 14 is slightly longer than the length 13 a of one side of the interval restricting portion 13 of the clip 101, and the inner width 14 b of the outlet portion is also equal to the interval restricting portion of the clip 101. 13 is slightly shorter than the length 13a of one side (14a> 13a> 14b). And both the inner width 15a and the depth length 15b of the space | interval control part arrangement | positioning hole 15 are longer than the length 13a of 1 side of the space | gap control part 13. As shown in FIG. For this reason, the space | interval control part 13 of the clip 101 which entered into the notch part 14 from the front part of the clip attachment seat 111 is pushed in, expanding the notch part 14, and is dropped and arrange | positioned at the space | interval control part arrangement | positioning hole 15. The In FIG. 3, reference numeral 16 denotes an inclined surface portion provided for facilitating the formation of the interval restricting portion arrangement hole 15.

  As shown in FIGS. 1 and 2, the inner wall portion of the cut portion 14 of the clip mounting seat 111 is extended toward the connection plate 11 side (downward) by a predetermined length. An engaged portion 18 that is engaged with an engaging portion 17 (described later) provided on the base portion 7 of 101 is provided. Each engaged portion 18 extends along the notch portion 14 of the upper plate portion 8 and from the peripheral edges on the left and right sides of the notch portion 14 toward the pillar garnish main body side (the connecting plate 11 side) rather than the engaging portion 17. Projected to be long. In each engaged portion 18, a surface (outer surface) that does not become the cut portion 14 side is formed in a plane parallel to the axis (center line) of the cut portion 14. Further, a protrusion 19 that extends from the front portion of the connecting plate 11 to the back surface of the clip mounting seat 111 is provided at a portion of the connecting plate 11 immediately below the notch portion 14. The functions of the engaged portion 18 and the protrusion 19 will be described later.

  Next, the clip 101 of the first embodiment will be described. The clip 101 of the present embodiment is made of an elastically deformable resin material. As shown in FIGS. 4 to 6, the clip main body 5 of the clip 101 has a cylindrical shape, and an insertion guide portion that is tapered so that it can be easily inserted into the clip mounting hole 4 a of the inner panel 2 at the tip. 5a is formed. Further, a dish-shaped stabilizer 21 made of a thin piece is provided at the proximal end portion of the clip main body portion 5 so as to protrude from the outer peripheral surface of the clip main body portion 5. A clip intermediate portion 22 having a diameter larger than that of the clip main body portion 5 is provided at the proximal end portion of the stabilizer 21 so as to be coaxial with the clip main body portion 5. Hereinafter, the side where the insertion guide portion 5a is provided in the clip main body portion 5 will be referred to as “upper side” and the side where the stabilizer 21 is provided will be referred to as “lower side” as necessary.

  A pair of movable claw members 23 are provided on the outer peripheral surface of the clip main body 5. The pair of movable claw members 23 are provided to face the axis 24 of the clip body 5 in the diametrical direction. Since the pair of movable claw members 23 have the same shape except that their directions are opposite, only one movable claw member 23 will be described. On the outer peripheral surface of the clip main body portion 5, a slit 25 is provided around a portion excluding the base end portion 23 a of the movable claw member 23. For this reason, the movable claw member 23 can be rotated along the axis perpendicular direction (horizontal direction orthogonal to the axis 24) of the clip main body 5 with the base end 23a as a fulcrum. The movable claw member 23 includes a clip body portion 5 from a claw portion 26 having a triangular cross section, a recess portion 27 provided at the lower end portion of the claw portion 26 and connected to the claw portion 26, and a lower end portion of the recess portion 27. And an operation piece 28 extending along the direction perpendicular to the axis. By pressing the operation piece 28 in the axial direction of the clip body 5 (direction along the axis 24), the movable claw member 23 can be rotated with the base end 23a as a fulcrum. In the stabilizer 21, a portion where the pair of operation pieces 28 are arranged is cut out.

  As the claw portion 26 of the movable claw member 23 moves toward the lower side of the clip main body portion 5, the amount of protrusion from the outer peripheral surface of the clip main body portion 5 gradually increases. In other words, the claw portion 26 is provided obliquely with respect to the axis 24 of the clip main body portion 5. For this reason, the claw part 26 of the movable claw member 23 protrudes outward from the outer peripheral surface of the clip main body part 5 in a normal state (a state where no external force is applied to the movable claw member 23). When the clip main body 5 is inserted into the clip mounting hole 4a of the inner panel 2, the claw 26 of the movable claw member 23 comes into contact with the inner peripheral surface of the clip mounting hole 4a. When the clip body portion 5 is further pushed in, the claw portion 26 of the movable claw member 23 is pressed against the inner peripheral surface of the clip mounting hole 4a, and rotates toward the inside of the clip body portion 5 with the base end portion 23a serving as a fulcrum. Is done. When the claw portion 26 of the movable claw member 23 passes through the clip mounting hole 4a, the movable claw member 23 is elastically restored (see FIG. 6). In this state, the clip mounting hole 4 a of the inner panel 2 is disposed to face the recess 27 of the movable claw member 23.

  At this time, the claw portion 26 of the movable claw member 23 is disposed on the inner side of the inner panel 2 beyond the clip mounting hole 4a. The inner surface of the clip mounting portion 4 is disposed close to the lower surface of the elastically restored claw portion 26, and the outer surface of the clip mounting portion 4 is disposed close to the upper surface of the stabilizer 21. In other words, the clip mounting portion 4 of the inner panel 2 is sandwiched between the claw portion 26 of the movable claw member 23 and the stabilizer 21. Thereby, the clip 101 inserted into the clip mounting hole 4a of the inner panel 2 is prevented from being pulled out.

  A clip intermediate portion 22 having a diameter larger than that of the clip main body portion 5 is provided below the stabilizer 21, and a holding plate portion 6 is provided below the clip intermediate portion 22. The presser plate portion 6 has a square plate shape and is provided with a pair of pressing pieces 29 protruding at positions orthogonal to the forming direction of the pair of operating pieces 28 (positions not overlapping with the pair of operating pieces 28 in plan view). It has been. Each pressing piece 29 is formed of a thin plate and is provided obliquely from the side surface portion of the pressing plate portion 6 toward the pedestal portion 7, and the tip portion thereof is in a state where no external force is applied to the clip 101 (clip In a state in which 101 is not attached to the clip attachment seat 111), it is arranged so as to protrude from the lower surface of the presser plate portion 6 toward the pedestal portion 7.

  Then, a prismatic interval restricting portion 13 is extended from the presser plate portion 6 so as to be coaxial with the clip body portion 5, and the base portion 7 is connected to the lower end portion of the interval restricting portion 13. The length of the space restricting portion 13 is slightly longer than the distance between the upper surface of the upper plate portion 8 of the clip mounting seat 111 and the lower surface of each engaged portion 18 (the thickness of the upper plate portion 8). Further, the thickness 7 a of the base portion 7 of the clip 101 is substantially the same as the distance 18 a between the lower surface of each engaged portion 18 and the upper end surface of the protrusion 19. For this reason, when the space | interval control part 13 of the clip 101 enters into the notch part 14 of the clip attachment seat 111, a slight distance is provided between the lower surface of the holding plate portion 6 and the upper surface of the upper plate portion 8 of the clip attachment seat 111. A gap of δ is formed, and a pair of pressing pieces 29 provided on the pressing plate portion 6 of the clip 101 presses the upper surface of the upper plate portion 8 of the clip mounting seat 111. Thereby, the gap in the height direction between the clip 101 and the clip mounting seat 111 is absorbed, and there is no possibility that the clip 101 will rattle in the height direction.

  Then, both end portions in the width direction of the base portion 7 of the clip 101 are bent upward in an L shape, and a pair of engaging portions 17 are formed. The pair of engaging portions 17 are formed so that their opposing surfaces are parallel. When the interval restricting portion 13 of the clip 101 enters the notch portion 14 of the clip attaching seat 111, the corresponding engaged portion of the clip attaching seat 111 is caused by the interval restricting portion 13 and each engaging portion 17 of the clip 101. 18 is sandwiched. That is, each engaging portion 17 of the clip and each engaged portion 18 of the clip mounting seat 111 are engaged.

  The operation when the clip 101 of the first embodiment is attached to the clip attachment seat 111 will be described. As shown in FIG. 5, the interval restricting portion 13 of the clip 101 is pushed into the cut portion 14 from the front portion of the clip mounting seat 111. As FIG. 3 shows, since the inner width 14a of the entrance part of the notch part 14 is larger than the length 13a of the one side of the space | interval control part 13, operation which pushes in the space | gap control part 13 of the clip 101 is easy. . At this time, as shown in FIG. 5, the pair of pressing pieces 29 of the clip 101 presses the upper surface of the upper plate portion 8 of the clip mounting seat 111, and the lower surface of the holding plate portion 6 and the upper plate portion of the clip mounting seat 111. A gap of a distance δ is formed between the upper surface of the clip 8 and the upper surface of the base portion 7 of the clip 101 is in contact with the lower surface of the engaged portion 18 of the clip mounting seat 111. Then, the pair of engaging portions 17 of the clip 101 holds the engaged portions 18 of the corresponding clip mounting seats 111. That is, the clip 101 is pushed in with the pair of engaging portions 17 and the respective engaged portions 18 of the corresponding clip mounting seats 111 engaged.

  As shown in FIG. 3, the interval restricting portion 13 of the clip 101 pushed into the notched portion 14 of the clip mounting seat 111 exceeds the notched portion 14 into the interval restricting portion arrangement hole 15 of the clip attaching seat 111. Be placed. The inner width 14b of the end portion (exit portion) of the cut portion 14 is slightly shorter than the length 13a of one side of the interval restricting portion 13, and the inner width 15a of the interval restricting portion arrangement hole 15 is equal to the interval restricting portion. It is slightly longer than the length 13a of one side of the part 13. For this reason, the space | interval control part 13 exceeding the notch part 14 of the clip attachment seat 111 is dropped and arrange | positioned at the space | interval control part arrangement | positioning hole 15. FIG. At this time, the operator feels a moderate feeling of moderation and can confirm that the clip 101 is attached to the clip mounting seat 111 with this feeling of moderation. In addition, it is possible to prevent the clip 101 arranged in the interval restricting portion arrangement hole 15 of the clip mounting seat 111 from being removed.

  Next, an operation when the pillar garnish 3 having the clip 101 attached to the clip attachment seat 111 is attached to the clip attachment hole 4a of the inner panel 2 will be described. As shown in FIG. 1, the operator presses the portion (the portion of each clip mounting seat 111) where each clip 101 is attached from the front side of the pillar garnish 3 toward the inner panel 2, and The insertion guide 5a is inserted into the clip mounting hole 4a of the inner panel 2. At this time, the pressing force of the operator's finger is directly transmitted to the clip 101 via the ridge 19 provided on the connecting plate 11 of the clip mounting seat 111. For this reason, the operator can attach the pillar garnish 3 to the inner panel 2 reliably. Moreover, since the insertion guide part 5a of the clip main body part 5 has a tapered shape, the work of inserting the clip main body part 5 into the clip mounting hole 4a of the inner panel 2 is easy. At this time, the pair of movable claw members 23 provided in the clip main body portion 5 are pressed against the clip mounting holes 4a by the claw portions 26, so that the clip main body is based on the base end portion 23a of each movable claw member 23. It is turned inward of the part 5. As shown in FIGS. 5 and 6, when the claw portions 26 of the pair of movable claw members 23 exceed the clip mounting hole 4 a portion of the clip mounting portion 4 of the inner panel 2, the clip mounting hole 4 a portion is The pair of movable claw members 23 are disposed between the lower surface of the claw portion 26 and the upper surface of the stabilizer 21. The pressing force of the clip mounting hole 4a does not reach each movable claw member 23, and each movable claw member 23 is elastically restored and rotated outward with the base end portion 23a as a fulcrum. As a result, the claw portions 26 of the pair of movable claw members 23 cover the clip mounting holes 4 a, so that the clip 101 is held in a secured state with respect to the clip mounting holes 4 a of the inner panel 2.

  When the clip 101 is extracted from the clip mounting hole 4a of the inner panel 2, the operation piece 28 is pushed downward. As a result, the movable claw member 23 is rotated inward of the clip main body 5 with the base end 23a as a fulcrum, and the claw 26 is retracted to the vicinity of the outer peripheral surface of the clip main body 5. The two clip mounting holes 4 a can pass through the portions of the movable claw members 23 in the clip main body 5. As a result, the clip body 5 of the clip 101 can be detached from the clip mounting hole 4a of the inner panel 2.

  Next, the operation of the clip 101 when the airbag 1 is deployed will be described. As shown in FIG. 1, when the airbag 1 is inflated, the end portion 3a of the pillar garnish 3 is bent, and the airbag 1 is deployed from the gap. In the case of the conventional clip 90, as shown in FIG. 7A, the length (the sandwiching length) in which the holding plate portion 91 and the base portion 92 of the clip 90 sandwich the upper plate portion 94 of the clip mounting seat 111. Since the length 95) is short, the upper plate portion 94 of the clip mounting seat 93 is easily expanded by the force when the airbag 1 is deployed, and the base portion 92 of the clip 90 is also easily bent. Thereby, the clip 90 and the clip mounting seat 93 of the pillar garnish 3 are easily separated.

  However, in the case of the present embodiment, as shown in FIG. 7B, the clip mounting seat 111 has a lower side from the end portion in the left-right direction of the upper plate portion 8 (the portion of the cut portion 14 in the upper plate portion 8). Each engaged portion 18 is extended. For this reason, the height H of the upper plate portion 8 is larger than the height 95 of the conventional upper plate portion 94 by the engaged portion 18. In addition, the interval restricting portion 13 of the clip 101 and each engaging portion 17 of the pedestal portion 7 hold the corresponding engaged portion 18 of the upper plate portion 8. The force that acts on the upper plate portion 8 of the clip mounting seat 111 when the airbag 1 is deployed will be described.

  In the conventional case, as shown in FIG. 7A, when the airbag 1 is deployed, the deployment force F acts on the clip mounting seat 93 to bend the upper plate portion 94. As a result, a bending moment M ′ acts on the upper plate portion 94 of the clip mounting seat 93. In other words, in the case of the conventional clip mounting seat 93, the clip 90 is held only by a force (bending resistance force) that opposes the bending moment M ′ of the upper plate portion 94.

  Even in the case of this embodiment, the upper plate portion 8 of the clip mounting seat 111 tends to be bent by the deploying force F of the airbag 1 as shown in FIG. (That is, the bending moment M acts). A bending resistance force that opposes the bending moment M acts on the upper plate portion 8 of the clip mounting seat 111. And the engaging part 17 of the base part 7 in the clip 101 holds the engaged part 18 of the corresponding upper plate part 8. Therefore, even if the upper plate portion 8 of the clip mounting seat 111 is bent and the clip 101 is about to be detached, the engaging portion 17 of the base portion 7 of the clip 101 corresponds to the engaged portion 18 of the clip mounting seat 111. A force Fa that presses the engaged portion 18 in the left-right direction acts along the left-right direction. This force Fa is a shearing force that attempts to shear the engaged portion 18 from the upper plate portion 8 of the clip mounting seat 111, and is extremely large. That is, in the case of the present embodiment, the clip mounting seat 111 holds the clip 101 by both the bending resistance force and the shearing force Fa that oppose the bending moment M of the upper plate portion 8, and therefore has a strong holding force. can get. As a result, even if the airbag 1 is deployed, the upper plate portion 8 of the clip mounting seat 111 is difficult to bend, and when the airbag 1 is deployed, the pillar garnish 3 is detached from the inner panel 2 of the vehicle. Can be prevented. Moreover, the engaging portion 17 and the engaged portion 18 are more engaged with each other by a force for pulling the pillar garnish 3 away from the inner panel 2 of the vehicle (that is, a force for pulling the clip 101 out of the clip mounting seat 111). You will receive a force in the direction to match. That is, the engagement portion 17 and the engaged portion 18 are engaged with each other, so that the spread of the cut portion 14 and the detachment of the clip 101 can be reliably prevented.

  Furthermore, engaging portions 17 for holding and engaging each engaged portion 18 of the clip mounting seat 111 are provided at both ends of the base portion 7 of the clip 101 in the width direction. Thereby, since the clip 101 is restrained in the width direction and attached to the clip mounting seat 111, the clip 101 is less likely to rattle in the width direction. As a result, the base portion 7 of the clip 101 is reliably prevented from being detached from the upper plate portion 8 of the clip mounting seat 111.

  Hereinafter, a clip and a clip mounting seat of another embodiment will be described. The engaging portion 17 of the clip 101 is engaged with the engaged portion 18 of the clip mounting seat 111 in a state where the upper plate portion 8 of the clip mounting seat 111 is sandwiched and is prevented from shifting in the width direction (left-right direction). If it is, it will not be restricted to the above-mentioned form. For example, the clip 102 of the second embodiment shown in FIG. 8A is a case where the distal end portions 34 of the engaging portions 17 of the pedestal portion 7 are further bent in a mutually opposing form. The clip mounting seat 112 is formed with a recess 35 for allowing the distal end portion 34 of each engaging portion 17 to enter. In the case of the clip 102 and the clip mounting seat 112 of this embodiment, when the upper plate portion 8 of the clip mounting seat 112 tries to bend, the tip end portion 34 of the engaging portion 17 of the clip 102 and the engaged portion of the clip mounting seat 112 are engaged. The bending of the upper plate portion 8 is also suppressed between the concave portion 35 of the portion 18. Thereby, the base part 7 of the clip 102 and the upper plate part 8 of the clip mounting seat 112 are more difficult to deform.

  Like the clip 103 of the third embodiment shown in FIG. 8B, the base portion 7 is provided with a plurality of engaging portions 36 in a comb-tooth shape, and the upper plate portion of the clip mounting seat 113. 8 may be a case where an engaged portion 37 corresponding to the engaging portion 36 of the clip 103 is provided in a comb-tooth shape on the lower surface of the clip 103.

  The clip 104 of the fourth embodiment shown in FIG. 9A is provided with a columnar engaging portion 38 in the depth direction on the pedestal portion 7 and the upper plate portion 8 of the clip mounting seat 114. This is a case where a groove 39 corresponding to the engaging portion 38 of the clip 104 is provided on the lower surface along the depth direction. Even with the clip 104 and the clip mounting seat 114 of this embodiment, the same effects as those of the first embodiment can be obtained.

  Moreover, like the clip 105 of 5th Example shown by FIG.9 (b), the engaging part 41 is made into a cross-section inverted trapezoid shape, and a to-be-engaged part is a clip mounting seat corresponding to the engaging part 41. It is good also as the groove part 42 (present groove part) provided in the lower surface of 115 upper-plate part 8. FIG.

  Also, like the clip 106 of the sixth embodiment shown in FIG. 10A, the upper surface of the upper plate portion 44 of the clip mounting seat 116 is raised at both ends of the holding plate portion 43 of the clip 106. The engaging portion 43 a that engages with the raised portion 44 a may be formed so that the clip 106 and the clip mounting seat 116 engage with each other not only in the base portion 7 but also in the holding plate portion 43.

  Furthermore, like the clip 107 of 7th Example shown by FIG.10 (b), each end surface part of the protruding part 44a of the upper board part 44 of the clip attachment seat 117 and the to-be-engaged part 45 is made into an inclined surface, The engaging portion 47 of the pedestal portion 46 and the engaging portion 43a of the presser plate portion 43 may have a dovetail shape corresponding to each inclined surface. In the case of the clips 106 and 107 of the sixth and seventh embodiments, since the upper and lower portions of the upper plate portion 44 of each clip mounting seat 116 and 117 are engaged, when the airbag 1 is deployed, The problem that the pillar garnish 3 is detached from the inner panel 2 of the vehicle can be more effectively prevented.

  In the clips 101 to 107 of the above-described embodiments, the clip main body 5 is provided with two movable claw members 23. However, three or more movable claw members 23 may be provided.
