Description

  The present invention relates to a vehicle interior member, and particularly to a front pillar garnish.

  A general airbag is folded and accommodated across a front pillar portion and a roof side rail portion at the periphery of an opening such as a window inside a vehicle. When the inflation gas flows into the airbag, the folded airbag is inflated to open the front pillar garnish, the roof head lining of the roof side rail portion, and the like (see, for example, Patent Document 1). ).

  The front pillar garnish includes a synthetic resin garnish main body and a clip that is assembled to the garnish main body and attaches the garnish main body to the vehicle body (see, for example, Patent Document 2).

  The airbag is attached to the front pillar portion of the vehicle body so as to be positioned on the side window side near the clip in a state where the front pillar garnish is attached to the vehicle body.

  The garnish body is pushed by the inflated airbag to open the edge of the airbag in the protruding direction (side window side) so that the airbag when inflated can protrude outward from the pillar garnish. Secured by side-mounted clips.

  This clip has an initial position holding part that holds the garnish body in an initial position where the airbag is not deployed and the garnish body covers the vehicle body, and the airbag is deployed, and the garnish body is opened from the vehicle body. And an anchor portion held at the moved position. When the clip is attached to the vehicle body side, the initial position holding portion and the anchor portion are inserted into the pedestal through a hole that protrudes from the garnish main body and is provided at the tip of the pedestal having a hollow inside. As a result, there are two locations: an initial position where the garnish body is attached to the vehicle body, and a movement position which is the position of the garnish body opened by the airbag when the airbag is inflated and protrudes. In position, the garnish body can be held.

  The anchor portion includes a shaft portion extending from the clip main body, and a first locking projection and a second locking projection that protrude so as to be orthogonal to the shaft portion at the tip of the shaft portion. The first locking protrusion and the second locking protrusion are opposed to each other, and the first locking protrusion has a larger protruding amount (projecting length) from the shaft portion than the second locking protrusion. Further, the first locking projection and the second locking projection protrude in opposite directions.

  When the clip holds the garnish body in the initial position, the tip of the shaft portion is bent in the protruding direction of the first locking projection. Thus, the garnish main body is opened by being pushed by the inflated airbag, and when the garnish main body moves from the initial position to the moving position, the first locking protrusion having a large protruding amount is formed before the second locking protrusion. It abuts on the periphery of the hole in the base. Therefore, even if the air bag is activated, the anchor portion of the clip is difficult to be removed from the hole of the pedestal, and the garnish body can be stably held by the clip.

Japanese Patent No. 3633537 JP 2010-168044 A

  In the garnish structure described above, when the airbag is inflated while the garnish body is attached to the vehicle body, the airbag is pushed by the airbag and the garnish body is detached from the vehicle body. However, when the front pillar garnish is attached to the vehicle body, it is attached to the front pillar portion of the vehicle body so as to be positioned on the side window side near the clip. Therefore, when the airbag is inflated, the garnish body opens from the side window side of the garnish body. Therefore, a force that rotates toward the windshield side of the garnish body is generated. In general, since the front end side of the front pillar garnish is locked to the vehicle body, the garnish main body is also simultaneously subjected to a force that rotates to the front side. For this reason, the pedestal does not try to come out in the direction along the clip with respect to the clip, but tries to come out by twisting from the clip. Then, before a predetermined force is applied to the garnish main body from the airbag, the pedestal may come off from the initial position holding portion of the clip, and the garnish main body may move to the movement position. In this case, since the garnish main body is vigorously detached from the vehicle body (the initial position holding portion of the clip) at the initial stage of airbag development, the passenger protection function may be impaired.

  The present invention solves the above-described problems, and provides a vehicle interior member in which the garnish body is prevented from being detached from the initial position holding portion of the clip before a predetermined force is applied from the airbag to the garnish body. For the purpose.

  The vehicle interior member of the present invention includes a garnish body and a clip that is locked to the vehicle body and the garnish body. The garnish main body includes a cover portion that covers the passenger compartment side of the vehicle body and a pedestal that protrudes from the back surface of the cover portion and has a hole on the surface facing the cover portion. The clip is provided on a flange that can come into contact with the surface on which the hole of the pedestal is provided, a vehicle body engaging portion that is provided on one surface of the flange and is locked to the vehicle body, and is provided on the other surface of the flange. An initial position holding portion and an anchor portion provided at the tip of the initial position holding portion. The initial position holding portion is an initial position where the garnish main body covers the vehicle body, and can hold the garnish main body with the surface where the hole of the pedestal is provided between the initial position holding portion and the flange. The anchor portion can hold the garnish body at a moving position where the garnish body is opened from the vehicle body. The surface on which the hole of the pedestal is provided and the flange are rectangular. Furthermore, at least one side of the peripheral edge of the surface where the hole of the pedestal is provided protrudes in the direction opposite to the cover, and the twist prevention prevents twisting of the garnish body while the garnish body is held in the initial position. Is provided.

  According to the present invention, since the pedestal can be prevented from twisting the clip when the airbag is deployed, the garnish body is detached from the initial position holding portion of the clip before a predetermined force is applied from the airbag to the garnish body. Can be prevented.

The cover portion 20 covers the inside of the front pillar portion of the vehicle body, and the vehicle of the cover portion 20 A pedestal 7 is provided on the outer surface (back surface) and engages with the clip 11.

  The airbag 40 (see FIG. 2) is located on one side of the garnish main body 6 in the short direction and on the side of the assembly seat 7 with the front pillar garnish 5 attached to the front pillar portion of the vehicle body. It is supposed to be.

  The pedestal 7 is on the back side of the cover part 20 of the garnish body 6, is disposed on the upper part of the garnish body 6, and is formed integrally with the cover part 20. And the base 7 is provided so that it may protrude from the back surface of the cover part 20, and the cross section has a substantially U shape. Specifically, the pedestal 7 includes a substantially rectangular locking plate 21 that faces the cover portion 20 with a gap, and a side wall 9 that connects the locking plate 21 and the cover portion 20. Yes. The side walls 9 may be provided only on the windshield side and the side window side of the locking plate 21.

  A hole 8 for locking the clip 11 is formed in the locking plate 21 so as to extend in the vertical direction of the cover portion 20. Furthermore, a guide plate 10 having one end attached to the inner surface of the side wall 9 on the windshield side and the other end attached to the cover portion 20 is provided.

  An anchor portion 14 and an initial position holding portion 13 to be described later are inserted into the hole 8, and the initial position holding portion 13 of the clip 11 and the flange 31 of the clip 11 define the hole 8 of the locking plate 21. It is assembled to the pedestal 7 so as to sandwich the periphery.

  A claw (not shown) is provided at the lower end of the cover portion 20 so as to engage with the vehicle body. Therefore, when the airbag 40 is inflated, the upper end side of the garnish body 6 is opened from the vehicle body by being pushed by the inflated airbag.

  Further, in the present invention, the torsion preventing portion 30 that protrudes from the peripheral portion of the locking plate 21 in the direction opposite to the cover portion 20, that is, from the vehicle inner side toward the vehicle outer side is provided. The torsion preventing portion 30 is provided at least at the edge of the locking plate 21 on the side window side. In the present embodiment, the torsion preventing portions 30 are also provided at the upper and lower ends of the locking plate 21.

  The clip 11 is formed from a synthetic resin such as an olefin-based thermoplastic elastomer. The grip 11 is provided on a substantially rectangular or substantially square plate-like flange 31, one surface of the flange 31, the vehicle body engaging portion 12 having an engaging claw 12 ′, and the other surface of the flange 31. The initial position holding part 13 slightly swelled from the short direction of the hole 8 (direction of the windshield and the side window) and the anchor part 14 extending from the initial position holding part 13. The canker portion 14 includes a shaft portion 15 extending from the initial position holding portion 13, a first engagement protrusion 16 and a second engagement protrusion 17 that protrude in a direction orthogonal to the shaft portion 15 from the tip of the shaft portion 15. Is provided. The first engagement protrusion 16 and the second engagement protrusion 17 protrude in directions opposite to each other. Further, the first engagement protrusion 16 has a larger protrusion amount (projecting length) than the second engagement protrusion 17.

  The vehicle body engagement portion 12 is inserted into a mounting hole (not shown) provided in the front pillar portion of the vehicle body, and the engagement claw 12 'of the vehicle body engagement portion 12 engages with the vehicle body. Even when the airbag 40 is operated, an engaging force is applied to the engaging claws 12 ′ and the vehicle body so that the engaging claws 12 ′ are not detached from the vehicle body.

  The initial position holding unit 13 is configured to hold the front pillar garnish body 6 at the initial position held by the initial position holding unit 13 of the clip 11 when the front pillar garnish 5 is attached to the front pillar portion of the vehicle body. The position holding portion 13 and the flange 31 sandwich the periphery of the hole 8 of the locking plate 21. In this initial position, the garnish body 6 covers the vehicle body. Note that the locking force of the initial position holding portion 13 to the periphery of the hole 8 of the locking plate 21 is such that the initial position holding portion 13 comes out of the hole 8 when the garnish body 6 is pressed against the inflating airbag. Is set to

  Next, the flow of assembling the clip 11 to the base 7 of the garnish body 6 will be described. First, the first engagement protrusion 16 and the second engagement protrusion 17 of the anchor portion 14 are inserted into the hole 8. Then, the clip 11 is rotated by approximately 90 ° with the shaft portion 15 as the rotation axis so that the second engagement protrusion 17 and the guide plate 10 face each other. In this state, the anchor portion 14 is further pushed into the base 7 and inserted. Then, the second engagement protrusion 17 is guided in contact with the guide plate 10, and the tip of the shaft portion 15 bends in a direction opposite to the guide plate 10 (a direction away from the guide plate 10). Then, the initial position holding portion 13 passes through the hole 8, and the initial position holding portion 13 and the flange 31 sandwich the periphery of the hole 8 of the locking plate 21 (see FIG. 2A). The front pillar garnish 5 is obtained by engaging a not-shown claw at the lower end of the cover portion 20 with the vehicle body, and holding the periphery of the hole 8 of the locking plate 21 between the initial position holding portion 13 and the flange 31. Is fixed to the car body.

  When the airbag 40 stored in the front pillar portion of the vehicle body expands, the garnish body 6 moves from the initial position so as to rotate around its lower end and the end on the windshield side, and the airbag 40 protrudes. (See FIG. 2 (b)). The position where the garnish body 6 is moved by the airbag 40 and opened from the vehicle body is defined as a movement position.

  In the state of the initial position, the shaft portion 15 of the anchor portion 14 is bent toward the first locking projection 16, and the first locking projection 16 is brought close to the periphery of the hole 8 of the locking plate 21. Therefore, when the garnish body 6 moves from the initial position to the moving position, the long first locking protrusion 16 comes into contact with the peripheral edge of the hole 8 of the locking plate 21, and the anchor portion 14 comes out of the hole 8. Is prevented. Therefore, even if the airbag 40 is inflated, the garnish body 6 is stably held at the movement position.

  Next, the effect of the torsion preventing portion 30 that is a feature of the present invention will be described. When the airbag is inflated with the front pillar garnish 5 attached to the vehicle body, the airbag 40 pushes out the garnish body 6, opens the side window on the upper side of the garnish body 6, and the gap between the vehicle body and the garnish body 6 Protrude from. At this time, as in the prior art, the garnish body 6 tries to rotate around the windshield side and tries to rotate around the lower end (see FIG. 3). However, in the present invention, by providing the torsion preventing portion 30 on the base 7, even if the garnish main body 6 is twisted and moved, the torsion preventing portion 30 and the flange 31 of the clip 11 come into contact with each other. Reduce torsion. Therefore, it is difficult for the initial position holding portion 13 of the clip 11 to come off the pedestal 7, and the garnish main body 6 moves from the initial position to the moving position before a predetermined force is applied from the airbag 40 to the garnish main body 6. Can be prevented.

  As shown in FIG. 4, a sawtooth (uneven shape) torsion preventing portion side meshing portion 30 ′ is formed on the inner surface of the torsion preventing portion 30, and the torsion preventing portion side of the torsion preventing portion 30 is formed on the flange 31. A flange side meshing portion 31 ′ that meshes with the meshing portion 30 ′ may be formed. In this way, even if a twisting force is applied to the clip 11, the torsion preventing portion side meshing portion 30 'and the flange side meshing portion 31' mesh with each other. The part 13 becomes more difficult to be removed from the base 7. The shapes of the torsion preventing portion side meshing portion 30 ′ and the flange side meshing portion 31 ′ are not particularly limited as long as they can be engaged with each other.

  In the prior art, there is a problem that the garnish body can be easily detached from the initial position holding portion of the clip. However, in the present invention, the garnish main body 6 (the pedestal 7) is not easily removed from the initial position holding portion 13 of the clip 11. For this reason, it is possible to prevent the garnish body 6 from coming off before a predetermined force is applied to the initial position holding portion of the clip 11. Moreover, since it is only necessary to provide the twist prevention part 30 in the base 7, it is also possible to suppress an increase in cost.
