BACKGROUND OF THE INVENTION
The present invention relates to a structure for attaching a fixing component for fixing a member to be attached to a mating member to the member to be attached.
[0002]
[Prior art]
Conventionally, as a simple method for fixing a member to be attached to a mating member, there is a method in which a clip made of resin or metal is attached to the back surface of the member to be fitted, and a leg portion of the clip is inserted and locked into a hole of the mating member. is there. For example, in a pillar garnish attached to a pillar portion of a vehicle body, a substantially horseshoe-shaped clip seat having an opening on one side is formed in advance on the back surface of the pillar garnish, and a known resin or metal clip head is formed from the opening. There is a type in which a clip is attached to the back side of a pillar garnish by inserting a portion into a seat portion, and a leg portion of the clip is inserted and engaged with a clip hole formed in an inner panel of a vehicle body pillar portion.
[0003]
However, in the structure in which the clip is attached to the clip seat as described above, the clip seat on the back surface of the attached member is open, so that the clip may be covered depending on the direction of the force applied to the attached member. It may come off from the clip seat portion of the mounting member.
[0004]
Particularly, in the pillar garnish of a vehicle, in recent years, in order to protect an occupant even in the case of a side collision of the vehicle, an airbag built-in type in which an airbag A is accommodated on the back side of the pillar garnish 80 as shown in FIGS. The thing has appeared. The airbag garnished pillar garnish 80 has the airbag A inflated by a side collision, and the inflation causes the pillar garnish 80 to be pushed and bent toward the interior of the vehicle interior, so that the airbag A is between the vehicle body pillar 95 and the pillar garnish 80. A passing gap 81 is formed, and the airbag A is deployed between the occupant head T and the wind glass G through the gap 81 like a chain line Bo to protect the occupant head T. Reference numeral I denotes an inflator of the airbag device, and P denotes an instrument panel.
[0005]
When the airbag built-in type pillar garnish is fixed to the vehicle with the clip as described above, when the airbag is inflated, the pillar garnish is deformed so as to be inflated by being strongly pushed toward the vehicle interior side. The clip seat on the back side of the pillar garnish moves with respect to the clip, and the clip comes out of the opening of the clip seat, which may cause the pillar garnish to come off the vehicle body pillar and scatter.
[0006]
Therefore, as shown in FIG. 7, a structure has been proposed in which the intermediate portion in the width direction of the pillar garnish 80 is securely locked to the inner panel 91 of the vehicle body pillar portion 95 with a rod-like fixing bracket 85 such as a bolt. Further, in order to prevent the enlarged head 86 of the rod-shaped fixing bracket 85 from being exposed on the design surface of the pillar garnish 80, that is, the surface on the vehicle interior side, the appearance of the pillar garnish 80 is not impaired. It is considered that a seat portion 81 is formed, and a head portion 86 of a rod-shaped fixing bracket 85 is embedded and fixed to the seat portion 81. In the drawing, F denotes a windshield, C denotes wiring from the engine room, 97 denotes an opening trim, 98 denotes a glass run channel, and 99 denotes a body frame.
[0007]
In the case of using the rod-shaped fixing bracket 85, the inner panel 91 of the vehicle body pillar portion 95 has a hole-like engagement hole 96 having a large-diameter hole 97 at one end as shown in FIG. It is formed at a predetermined position along the longitudinal direction of 80. When the pillar garnish 80 is attached, the distal end locking portion 88 of the rod-shaped fixing bracket 85 is inserted into the large-diameter hole 97 of the locking hole 96, and the rod-shaped fixing bracket 85 together with the pillar garnish 80 is locked into the locking hole 96. The rod-shaped fixture 85 is locked in the locking hole 96 of the inner panel 91 by sliding in the direction of the smaller diameter of the inner panel 91.
[0008]
However, according to the fixing structure using the rod-shaped metal fitting 85, the problem relating to the detachment of the pillar garnish 80 when the airbag is inflated and deployed is solved. However, when the pillar garnish 80 is molded, the molding die is shaped like a rod. Since the fixing metal 85 must be disposed and insert molding is performed, the molding operation becomes complicated and the cost increases. Further, since the resin pillar garnish 80 is integrally formed with the metal rod-shaped fixing bracket 85, it is necessary to separate the metal rod-shaped fixing bracket 85 and the resin at the time of recycling. It is troublesome and has a problem of poor recyclability.
[0009]

Further, as shown in FIG. 1, the rear surface of the pillar garnish 40 is provided with a required number of two types of attachment portions 10 and 46 alternately at a required interval along the longitudinal direction. The attachment portions 10 and 46 are used for attachment to the inner panel 50. One is the attachment portion 10 for preventing the pillar garnish detachment when the airbag A is inflated, and the other is the attachment portion 46 for holding in a normal state. . When the pillar garnish 40 is attached to the vehicle, the lower end 40a of the pillar garnish 40 is inserted and fixed in a hole (not shown) formed in the instrument panel P in FIG. 5 described in the section of the prior art, The detachment preventing mounting portion 10 and the holding mounting portion 46 are fixed to the inner panel 50 of the vehicle.
[0016]
A fixing component mounting seat 11 for mounting the fixing component 20 is formed on the detachment preventing mounting portion 10. As shown in FIGS. 2 and 3, the fixed component 20 has an attached member (pillar garnish) side locking portion 21 at one end of a shaft portion 23, and an inner panel 50 of a vehicle at an opposite end portion. A mating member-side fixing portion 25 for fixing to the base is formed in an appropriate shape. The fixed component 20 is made of metal or high-strength resin. Further, the attached member side locking portion 21 and the mating member side fixing portion 25 of the fixed component 20 in this example are both disc-shaped with a diameter larger than the diameter of the shaft portion 23, but are not limited thereto. Instead, a rectangular parallelepiped or a cube larger than the diameter of the shaft portion 23 may be used.
[0017]
The fixed component mounting seat 11 is a hollow box-shaped member composed of a side surface 11a and a seat surface 11b. In this example, one side surface (below the pillar garnish 40) is an opening 11c. The seat surface 11b is provided at a required distance from the back surface of the pillar garnish 40, and the attachment member side locking portion 21 of the fixed component 20 is accommodated between the seat surface 11b and the back surface of the pillar garnish 40. It can be done. The seating surface 11 b is formed with a fixed component passage 12 including an insertion side passage 13 and a holding side passage 15, and a locking portion insertion space 17 is provided between the fixed component passage 12 and the back surface of the pillar garnish 40. ing.
[0018]
The insertion-side passage 13 is a long hole having an outer end 13 a that opens to the opening 11 c of the fixed component mounting seat 11 and an inner end that is closed, and is formed along the longitudinal direction of the pillar garnish 40. ing. The insertion-side passage 13 has such a width that the shaft portion 23 of the fixed component 20 can be inserted therethrough and the attached member-side locking portion 21 cannot pass (cannot be removed). The fixing component 20 is pivoted from the opening of the outer end 13a of the insertion side passage 13 so that the attached member side locking portion 21 is positioned between the seat surface 11b and the back surface of the pillar garnish 40. The part 23 is inserted into the insertion side passage 13.
[0019]
The holding-side passage 15 has a long hole shape that communicates with the inner end of the insertion-side passage 13 and bends in an L shape with respect to the insertion-side passage 15. Similarly to the insertion-side passage 13, the holding-side passage 15 has a width that allows the shaft portion 23 of the fixed component 20 to be inserted, and prevents the attached member-side locking portion 21 from passing (not detaching). Then, the shaft portion 23 of the fixed component 20 inserted into the insertion side passage 13 is moved into the holding side passage 15 by changing the direction at the bent portion 12a between the insertion side passage 13 and the holding side passage 15, and the seat surface. The attached member side locking portion 21 is accommodated in the locking portion insertion space 17 between the holding side passage 15 portion of 11 b and the back surface of the pillar garnish 40. The bent portion 12a between the insertion side passage 13 and the holding side passage 15 may be chamfered or set at a predetermined angle so that the shaft portion 23 of the fixed component 20 can smoothly move from the insertion side passage 13 to the holding side passage 15. , May be arcuate. Further, in this embodiment, the holding-side passage 15 is bent in a substantially L shape at the inner end of the insertion-side passage 13 via the bent portion 12a, so that the shaft portion 23 of the fixed component 20 is inserted into the insertion-side passage 13. It is possible to move smoothly from the holding side passage 15 to the holding side passage 15.
[0020]
As shown in FIGS. 2 to 4, a fixed component removal preventing member 30 is attached to the insertion side passage 13 after the fixing component 20 is moved to the holding side passage 15, and the insertion side passage 13 and the holding side passage are arranged. The bent portion 12a between 15 is closed. Accordingly, the shaft portion 23 of the fixed component 20 is prevented from moving to the insertion side passage 13. The fixed component removal preventing member 30 is an appropriate member capable of closing the bent portion 12a. In this example, the fixed component removal preventing member 30 is formed of an elongated resin product extruded into a substantially E-shaped cross section. The both edges of the insertion-side passage 13 are clamped by 31 and 31.
[0021]
As described above, since the shaft portion 23 of the fixing component 20 is positioned in the holding-side passage 15 that intersects or bends with respect to the insertion-side passage 13, the direction along the insertion-side passage 13 along the fixing component 20 when the airbag is inflated. The fixing component 20 does not come out through the insertion side passage 13 even if the force is applied, and even if a force in a direction along the holding side passage 15 is applied to the fixing component 20, the fixing component 20 is held with the insertion side passage 13. Since the bent portion 12a between the side passages 15 is blocked by the fixed component removal preventing member 30, the movement of the fixed component 20 to the insertion side passage 13 is prevented and does not come off. Further, in this example, ribs 16 are erected on the back surface of the pillar garnish 40 corresponding to the insertion-side passage 13 up to the vicinity of the bent portion 12a. The distance between the tip of the rib 16 and the seating surface 11b is a distance through which the attached member side engaging portion 21 of the fixed component 20 can pass, and the attached member side engaging portion 21 once moved to the holding side passage 15 is ribbed. The presence of 16 makes it more difficult to move to the insertion side passage 13. In addition, if this rib 16 is provided also on the back surface of the pillar garnish 40 corresponding to the holding-side passage 15, it is useful for preventing rattling of the fixed component 20 in normal times.
[0022]
On the other hand, the holding attachment portion 46 in the normal state is constituted by a clip seat portion 61. A known metal or resin clip (not shown) is fixed to the clip seat 61, and the clip is inserted into a clip hole (not shown) formed in the inner panel 50 of the vehicle. It comes to match. By attaching the pillar garnish 40 to the inner panel 50, the clip fixes the pillar garnish 40 to the inner panel 50 in a normal state, and when the pillar garnish 40 is pushed up by inflation of the airbag A, the clip is attached to the inner panel 50. It comes out of the clip hole.
[0023]
The pillar garnish 40 of this embodiment is fixed to the inner panel 50 in the same manner as before. That is, in the detachment preventing mounting portion 10, the mating member side fixing portion 25 of the fixing component is inserted into the large diameter hole portion of the fistula-shaped locking hole 53 formed in the inner panel 50, and then moves to the small diameter 53 a side. In this way, the pillar garnish 40 is slid. Further, in the holding attachment portion 46 in the normal state, the clip is positioned on the clip hole of the inner panel 50 by the slide of the pillar garnish 40, and the pillar garnish 40 is strongly pressed toward the inner panel 50 side at the position. This is done by inserting and engaging the clip into the clip hole.
[0024]
The fixed component passage 12, that is, the insertion side passage 13 and the holding side passage 15 are called grooves as long as the attached member side locking portion 21 of the fixed component 20 can be locked. There may be.
[0025]
【The invention's effect】
As described above, according to the fixing part mounting structure of the present invention, it is not necessary to insert-mold the fixing part at the time of forming the mounting member. There is an effect that the attaching operation of the fixed component to the attached member can be easily performed. Moreover, since the fixed component is hidden behind the attached member, the appearance of the attached member can be improved without using a cover lid or the like. Furthermore, the shaft part of the fixed part is positioned in the holding side passage that intersects or bends with respect to the insertion side path in the fixed part mounting seat, and the bent part between the insertion side path and the holding side path is blocked by the fixing part removal prevention part. Therefore, even if a large force is applied to the mounted member or the fixed component, the fixed component does not fall out of the mounted member. Furthermore, at the time of repair and recycling of the mounted member, the mounted member and the fixed component can be separated by removing the fixed component removal preventing component, and the work can be easily performed.
[0026]
In addition, since the holding side passage is bent and communicated with the inner end of the insertion side passage in a substantially L shape , the shaft portion of the fixed part can be easily moved from the insertion side passage to the holding side passage. , Fixed parts can be easily and reliably attached.
[0027]
If the attached member is a pillar garnish with a built-in airbag and the mating member is an inner panel of the vehicle as in the invention of claim 2, the pillar garnish is applied even if an extremely large force is applied to the pillar garnish and the fixing part when the airbag is inflated. Can be separated from the fixed parts and scattered, and the fixed parts are not exposed on the surface of the pillar garnish without using a cover lid, so that the appearance can be improved without troublesome work and cost increase. it can.
