Thereby, a passenger | crew's safety can be ensured.

JP 2010-254136 A

  Incidentally, in the front pillar trim of Patent Document 1, a plurality of ribs (crossing ribs and reinforcing ribs) are formed on the back surface (the surface on the side where the bag body is disposed) of the trim body. For this reason, when a bag body expand | swells, it is anxious about a bag body being caught on a rib. Thereby, the stress resulting from the expansion pressure of the bag body locally acts on the trim body, and there is a concern that the trim body is partially deformed.

  This invention is completed based on the above situations, Comprising: It aims at providing the pillar garnish which can suppress the situation where a curtain shield airbag is hooked on a rib at the time of expansion | deployment.

  In order to solve the above problems, a pillar garnish according to the present invention is a pillar garnish attached to a vehicle interior side of a pillar panel in a vehicle, has a plate shape, and a curtain shield airbag is sandwiched between the pillar garnish and the pillar panel. A base material arranged in a shape, a rib standing from a surface of the base material on the curtain shield airbag side, and a base material provided at a peripheral end portion adjacent to a flange portion of the pillar panel. A protrusion projecting toward the flange portion of the pillar panel, wherein at least a part of the rib is disposed to face the curtain shield airbag, and the curtain shield air in the part of the rib The facing surface of the bag faces the deployment direction of the curtain shield airbag as it goes toward the peripheral edge of the base material. Characterized in being an inclined surface inclined in the form.

  In the present invention, the surface of the rib that faces the curtain shield airbag is an inclined surface that is inclined toward the deployment direction of the curtain shield airbag as it goes toward the peripheral edge of the base material. As a result, the curtain shield airbag is inflated, and, for example, when the curtain shield airbag is deployed in the vehicle interior from between the peripheral end portion of the base member and the flange portion of the pillar panel, the curtain shield airbag extends along the facing surface. Thus, it is guided in the deployment direction. As a result, it is possible to suppress a situation in which the curtain shield airbag is caught by the ribs during deployment.

  Thereby, it is possible to suppress a situation in which stress is locally applied to the base material due to the curtain shield airbag being caught by the rib. Moreover, since the curtain shield airbag is guided in the deployment direction by the facing surface, the curtain shield airbag can be deployed more smoothly.

  Moreover, the protrusion part which protrudes toward the flange part of a pillar panel is provided in the peripheral edge part of the base material. Thereby, when a base material is pressed by the pillar panel side, a deformation | transformation of a base material can be prevented because a protrusion contact | abuts to the flange part of a pillar panel.

  The said structure WHEREIN: The said protrusion shall be protruded toward the weather strip attached to the said flange part of the said pillar panel.

  With such a configuration, when the base material is pressed toward the pillar panel, the protrusion can be in contact with the weather strip, thereby preventing the base material from being deformed. And if it is set as the structure which makes a protrusion contact | abut on the weather strip which is a member which has a softness | flexibility, the situation where abnormal noise generate | occur | produces at the time of contact | abutting can be suppressed.

  The base material has a longitudinal shape, and one end portion in the longitudinal direction of the base material is arranged adjacent to a ceiling interior material provided in the vehicle, and the protrusion is provided at the one end portion. It can be assumed that

  The protrusion can prevent deformation of one end portion (a portion adjacent to the vehicle interior material for the ceiling) in the longitudinal direction of the base material. Thereby, the situation which a clearance gap produces between the interior material for ceilings and the one end part of a base material can be suppressed reliably, and design nature can be made higher.

  In addition, a clip seat capable of holding a clip attached to the pillar panel is provided on a surface of the base material on the curtain shield airbag side, and the projecting portion has an outer periphery than the clip seat in the base material. It can be provided at a location on the side.

  Since the location where the clip seat is provided on the base material is fixed to the pillar panel via the clip, the location becomes relatively difficult to deform. On the other hand, in the base material, the portion that is on the outer peripheral side of the clip seat is far from the clip seat, and thus is a portion that is relatively easily deformed. For this reason, a deformation | transformation of the said location can be effectively suppressed by forming a protrusion in the location which becomes an outer peripheral side rather than a clip seat in a base material.

  In addition, a clip seat capable of holding a clip attached to the pillar panel is provided on a surface of the base material on the curtain shield airbag side, and the clip seat is integrated with the base material using a slide mold. And has an opening that allows the slide mold to be removed from the mold, and the protrusion is formed on the base material with respect to the opening direction side of the opening rather than the clip seat. It can be provided in the place.

  When the clip seat is formed using a slide mold, it is difficult to form a reinforcing member such as a rib at a location on the base that is on the opening direction side of the opening (the slide mold releasing direction side). This is because if ribs are provided at such locations, they interfere with the ribs when the slide mold is removed. Therefore, in the present invention, the protrusion is provided in the base material at a position closer to the opening direction side of the opening than the clip seat. Thereby, in a base material, a deformation | transformation of the location where it is difficult to provide a rib (location where rigidity tends to become low) can be suppressed effectively.

  ADVANTAGE OF THE INVENTION According to this invention, the pillar garnish which can suppress the situation where a curtain shield airbag is hooked on a rib at the time of expansion | deployment can be provided.

The weather strip 14 includes a main body portion 14A attached to the flange portion 20B from the vehicle rear side, a lip portion 14B extending from the main body portion 14A, and covering a peripheral end portion of the pillar garnish 30 on the door opening 13 side from the vehicle interior side. It is equipped with.

  The main body portion 14A is attached so as to sandwich the flange portion 20B. The main body portion 14A is interposed between a side door (not shown) that closes the door opening 13 and the door opening 13 in a compressed state, so that the main body portion 14A enters the vehicle interior from the gap between the front pillar 20 and the side door. And has the function of preventing water from entering.

  A weather strip 16 is attached to a side end portion of the front window 15. The weather strip 16 closes a gap between the front pillar 20 and the front window 15. The weather strips 14 and 16 are made of an elastic material (rubber or the like) having flexibility, for example.

  Next, the configuration of the pillar garnish 30 will be described. The pillar garnish 30 includes a base material 31 having a plate shape. The base material 31 is formed of, for example, a synthetic resin material (polypropylene or the like). In addition, the material of the base material 31 is not limited to this, It can change suitably.

  As shown in FIGS. 1 and 2, the base material 31 has a longitudinal shape extending along the extending direction of the front pillar 20. An attachment piece 41 that is attached to, for example, a side panel (not shown) is formed at the lower end of the base material 31. Further, the upper end portion (one end portion in the longitudinal direction) of the base material 31 is disposed adjacent to the peripheral end portion of the ceiling interior material 10 provided in the vehicle.

  As shown in FIG. 5, the base material 31 is disposed in such a manner that the curtain shield airbag 25 is sandwiched between the base pillar 31 and the front pillar 20. The base material 31 includes a main body portion 32 (first wall portion) disposed to face the front pillar 20, and an extending portion 33 (second wall portion) extended in a shape bent with respect to the main body portion 32. I have. A skin material (not shown) is affixed to the surface of the base 31 on the vehicle interior side.

  The main body portion 32 is curved so as to bulge toward the vehicle interior side. The extending portion 33 extends from the peripheral end portion of the main body portion 32 on the vehicle rear side (lower side in FIG. 5) toward the flange portion 20 </ b> B of the front pillar 20. An end surface 33A (a peripheral end portion of the base material) of the extending portion 33 is disposed adjacent to the main body portion 14A of the weather strip 14 and, consequently, the flange portion 20B.

  The curtain shield airbag 25 is accommodated between the base material 31 and the inner panel 21 in a folded state, for example. The curtain shield airbag 25 is attached to the inner panel 21 with a clip (not shown) or the like. The curtain shield airbag 25 is disposed at the vehicle rear end portion of the base material 31 and is adjacent to the extending portion 33 of the base material 31. The curtain shield airbag 25 may be folded in a bellows shape, for example.

  As shown in FIG. 6, a clip seat 42 is erected on the back surface (surface on the curtain shield airbag side) of the main body portion 32 toward the inner panel 21. The clip seat 42 is for holding the clip 50 attached to the inner panel 21, and has a seat surface portion 43 that is disposed to face the inner panel 21. The seat surface portion 43 is formed with a seat surface portion side mounting hole 43A through which the clip 50 is attached.

  The clip 50 is formed of, for example, a synthetic resin and has a plate-like flange portion 51 (main body portion), a panel-side attachment portion 52 that protrudes from the flange portion 51 toward the inner panel 21, and a seat surface portion from the flange portion 51. It is mainly composed of a base material side mounting portion 53 protruding to the 43 side.

  The panel side attaching part 52 is comprised as a pair of locking piece. The panel-side attachment portion 52 is attached by being inserted through a panel-side attachment hole 21 </ b> A formed through the inner panel 21. The pair of locking pieces constituting the panel-side mounting portion 52 can be elastically deformed so as to narrow the interval between the opposing pieces.

  Thus, the panel side mounting portion 52 can be elastically deformed to be inserted into the panel side mounting hole 21A from the vehicle interior side. After the insertion, the panel side mounting portion 52 is elastically restored, so that the panel side mounting is performed. It is configured to be locked from the outside of the passenger compartment with respect to the hole edge portion of the hole 21A.

  A pair of locking projections 54 are formed at the base end of the base material side mounting portion 53. The pair of locking protrusions 54 are elastically deformable and can be locked from the vehicle interior side with respect to the hole edge portion of the seating surface portion side mounting hole 43A.

  The distal end side of the base material side attachment portion 53 is an anchor portion 55 bent toward the vehicle rear side. The anchor portion 55 is a portion that is locked to the seat surface portion 43 after the pair of locking projections 54 are released from the seat surface portion 43 when the curtain shield airbag 25 is inflated. The Specifically, the distal end portion of the anchor portion 55 is a locking portion 56 that can be locked from the vehicle interior side with respect to the hole edge portion of the seating surface portion side mounting hole 43A.

  The clip seat 42 is provided at a plurality of locations (two locations in the present embodiment) along the extending direction of the base material 31. Thereby, the base material 31 is configured to be attached to the inner panel 21 via the plurality of clips 50.

  Further, as shown in FIG. 3, the clip seat 42 has an opening 45 opened toward the outer peripheral side of the base material 31. The opening direction of the opening 45 is along the longitudinal direction of the base material 31. In the present embodiment, the clip seat 42 is formed integrally with the base material 31 by, for example, injection molding.

  When the base material 31 and the clip seat 42 are injection-molded, both the front and back surfaces of the base material 31 are molded by the molding surfaces of the pair of molding dies, respectively. In this case, the seat surface portion 43 of the clip seat 42 is an undercut portion. For this reason, in order to shape | mold the clip seat 42 which has the seat surface part 43 by injection molding, a slide type | mold (not shown) is used.

  The opening 45 is formed when the clip seat 42 is formed using a slide mold, and the slide mold can be removed. Specifically, when the clip seat 42 is formed, the clip seat 42 is formed in a state in which a slide mold is fitted in the opening 45. Then, after the clip seat 42 is formed, the slide mold is removed from the opening 45. That is, the opening direction of the opening 45 (corresponding to the arrow line D1 shown in FIG. 3) coincides with the slide-type punching direction.

  As shown in FIG. 3, a plurality of ribs 34 are erected on the back surface 31 </ b> A (surface opposite to the design surface) of the base material 31. Each rib 34 extends along the short side direction of the substrate 31. The plurality of ribs 34 are arranged along the long side direction of the base material 31.

  The rib 34 extends over both the main body portion 32 and the extending portion 33, and increases the rigidity of the base material 31. In the following description, a portion of the rib 34 formed on the main body portion 32 is referred to as a first rib 35, and a portion formed on the extending portion 33 is referred to as a second rib 36 (part of the rib). To do. The second rib 36 is bent with respect to the first rib 35 and is disposed to face the curtain shield airbag 25 (see FIG. 6).

  As shown in FIG. 3, the standing height of the first rib 35 is constant over the entire length. On the other hand, as shown in FIG. 6, the second rib 36 extends from the base end of the extending portion 33 (the boundary portion between the main body portion 32 and the extending portion 33). It extends over the tip of the. As shown in FIG. 6, the second rib 36 has a standing height (a height based on the back surface 33 </ b> B of the extending portion 33) extending from the base end of the extending portion 33. It becomes small as it goes to the tip (end face 33A side).

  For this reason, the facing surface 36 </ b> A of the second rib 36 facing the curtain shield airbag 25 is an inclined surface that is inclined with respect to the back surface 33 </ b> B of the extending portion 33. 36 A of opposing surfaces are extended in the direction which goes to the direction (vehicle interior side) away from the curtain shield airbag 25 as it goes to the end surface 33A of the extension part 33. As shown in FIG. In other words, the facing surface 36 </ b> A extends in a direction approaching the back surface 33 </ b> B of the extending portion 33 as it goes toward the end surface 33 </ b> A of the extending portion 33.

  The standing height of the second rib 36 is substantially the same as the standing height of the first rib 35 at the base end (first rib 35 side), and at the tip (end surface 33A side) thereof, It is almost zero.

  The curtain shield airbag 25 of the present embodiment can be deployed on the vehicle rear side (lower side in FIG. 6). It can be said that the facing surface 36A of the second rib 36 is an inclined surface that inclines in a direction toward the deployment direction of the curtain shield airbag 25 as it goes toward the end surface 33A.

  The boundary portion between the facing surface 35A of the first rib 35 facing the curtain shield airbag 25 and the facing surface 36A of the second rib 36 is curved so as to move away from the curtain shield airbag 25 as shown in FIG. The curved surface 37 is obtained.

  As shown in FIG. 5, the end surface 33 </ b> A of the extending portion 33 is adjacent to the flange portion 20 </ b> B of the front pillar 20. A plurality of protrusions 60 are formed on the end face 33A as shown in FIGS. A plurality (four in the present embodiment) of the protrusions 60 are arranged at predetermined intervals along the longitudinal direction of the end face 33A.

  As shown in FIG. 5, the protrusion 60 protrudes from the end face 33A toward the flange portion 20B. More specifically, the protrusion 60 protrudes toward the main body portion 14A of the weather strip 14 attached to the flange portion 20B. Note that the protruding direction of the protrusion 60 is slightly inclined with respect to the extending direction of the extending portion 33.

  As shown in FIG. 4, the protrusion 60 has a substantially trapezoidal shape whose width becomes narrower toward the tip in plan view. The protruding end of the protrusion 60 is in contact with the main body 14 </ b> A of the weather strip 14. Note that the protruding end of the protruding portion 60 may be arranged with a slight gap with respect to the main body portion 14 </ b> A of the weather strip 14.

  Further, as shown in FIG. 3, among the plurality of protrusions 60, the protrusion 60 (reference numeral 60 </ b> A) provided at one end in the longitudinal direction of the base material 31 is the clip seat 42 in the base material 31. It is provided in the location which becomes the outer peripheral side.

  Further, the protrusion 60 </ b> A is provided on the base material 31 at a location closer to the opening direction side of the opening 45 than the clip seat 42. In the present embodiment, the opening direction of the opening 45 is along the longitudinal direction of the base material 31, and the protrusion 60 </ b> A is located at one end side of the clip seat 42 in the longitudinal direction of the base material 31. Is provided.

  The present embodiment is configured as described above, and its operation will be described subsequently. When the curtain shield airbag 25 is activated, gas is supplied to the curtain shield airbag 25 from an inflator (not shown) and the curtain shield airbag 25 begins to expand.

  When the curtain shield airbag 25 interposed between the inner panel 21 and the base material 31 is inflated, the vehicle rear end side of the base material 31 receives pressure. Thereby, the extending part 33 of the base material 31 is bent and deformed rearward of the vehicle with the base end side as a fulcrum, for example. As a result, the distance between the end surface 33A of the extending portion 33 and the weather strip 14 is increased.

  At the same time, the curtain shield airbag 25 is deployed on the rear side of the vehicle through the space between the extending portion 33 and the weather strip 14 while being guided by the facing surface 36A of the second rib 36 (see FIG. 7). The deployed curtain shield airbag 25 is finally arranged so as to cover the side of the vehicle interior of the side door (not shown).

  Further, when the curtain shield airbag 25 is activated, the rear side of the base 31 is pressed against the curtain shield airbag 25. Thereby, the base material 31 tries to turn to the vehicle interior side by using the vehicle front end side as a fulcrum. For this reason, the clip seat 42 is pressed in a direction away from the inner panel 21.

  Then, the pair of locking projections 54 of the clip 50 is bent and deformed by being pressed against the hole edge portion of the seating surface portion side mounting hole 43A, and passes through the seating surface portion side mounting hole 43A. Thereby, the locking of the pair of locking protrusions 54 with respect to the seat surface portion 43 is released.

  After the locking of the pair of locking protrusions 54 is released, the base material 31 rotates toward the vehicle interior side. And when the base material 31 rotates to the vehicle interior side, the latching | locking part 56 of the anchor part 55 is latched from the vehicle interior side with respect to the hole edge part of 43 A of seat surface part side attachment holes. That is, in this embodiment, the first position (the position shown in FIG. 6) where the pair of locking projections 54 are locked to the seat surface portion 43, and the first position where the locking portion 56 of the anchor portion 55 is locked to the seat surface portion 43. The base material 31 can be held at two positions, ie, two positions.

  In addition, although the bending deformation of the extension part 33 mentioned above and the rotation to the vehicle interior side of the base material 31 shall be substantially the same timing, for example, it is not limited to this. Further, FIG. 7 illustrates an initial stage where the bending deformation of the extending portion 33 starts. At this stage, for example, a pair of locking protrusions 54 are locked to the seat surface portion 43.

  Next, the effect of this embodiment will be described. In the present embodiment, the facing surface 36A of the second rib 36 facing the curtain shield airbag 25 is an inclined surface that inclines in a direction toward the deployment direction of the curtain shield airbag 25 toward the end surface 33A of the base material 31. The As a result, when the curtain shield airbag 25 is inflated and deployed in the vehicle interior from between the end surface 33A of the base material 31 and the flange portion 20B of the front pillar 20, the curtain shield airbag 25 is opposed to the opposing surface 36A. In this way, it will be guided in the deployment direction. As a result, it is possible to prevent the curtain shield airbag 25 from being caught by the second rib 36 during deployment.

  Accordingly, it is possible to suppress a situation in which stress is locally applied to the base material 31 due to the curtain shield airbag 25 being hooked on the second rib 36. Further, since the curtain shield airbag 25 is guided in the deployment direction by the facing surface 36A, the curtain shield airbag 25 can be deployed more smoothly.

  Further, the end surface 33 </ b> A of the base material 31 is provided with a protrusion 60 that protrudes toward the flange portion 20 </ b> B of the front pillar 20. Thereby, when the base material 31 is pressed to the front pillar 20 side, the protruding end of the protrusion 60 abuts on the weather strip 14 attached to the flange portion 20B of the front pillar 20, thereby Deformation can be prevented.

  Conventionally, as a configuration for preventing the base material 31 from being deformed when pressed to the front pillar 20 side, a configuration in which a rib such as the second rib 36 is brought into contact with the weather strip 14 can be considered. However, in the present embodiment, the height of the second rib 36 is reduced toward the end face 33A. For this reason, it is difficult to bring the second rib 36 into contact with the weather strip 14. Therefore, in the present embodiment, the protrusion 60 is provided to suppress the deformation of the base material 31.

  Further, the protrusion 60 protrudes toward the weather strip 14 attached to the flange portion 20 </ b> B of the front pillar 20.

  With such a configuration, when the base material 31 is pressed toward the front pillar 20, the protrusion 60 abuts on the weather strip 14, thereby preventing the base material 31 from being deformed. And if it is set as the structure which makes the protrusion 60 contact | abut on the weather strip 14 which is a member which has a softness | flexibility, the situation where abnormal noise will be generated at the time of contact | abutting can be suppressed.

  As shown in FIG. 4, the projecting end surface of the projecting portion 60 (projecting portion 60 </ b> A) has a longitudinal shape, and thus can be brought into contact with the weather strip 14 more reliably.

  The base material 31 has a longitudinal shape, and one end portion in the longitudinal direction of the base material 31 is disposed adjacent to the ceiling interior material 10 provided in the vehicle, and the protrusion 60 is provided at this one end portion. It has been.

  The protrusion 60 can prevent deformation of one end portion of the base material 31 in the longitudinal direction (upper end portion, a portion adjacent to the vehicle interior interior material 10). Thereby, the situation which a clearance gap produces between the interior material 10 for ceilings and the one end part of the base material 31 can be suppressed reliably, and design nature can be made higher.

  Further, a clip seat 42 capable of holding a clip 50 attached to the front pillar 20 is provided on the back surface 31 </ b> A of the base material 31. Is provided.

  Since the location where the clip seat 42 is provided in the base material 31 is fixed to the front pillar 20 via the clip 50, the location becomes relatively difficult to deform. On the other hand, in the base material 31, since the location which becomes an outer peripheral side rather than the clip seat 42 becomes far from the clip seat 42, it becomes a location which is relatively easily deformed. For this reason, in the base material 31, the protrusion 60A is formed at a location on the outer peripheral side of the clip seat 42, so that deformation of the location can be effectively suppressed.

  Further, the clip seat 42 is injection-molded integrally with the base material 31 using a slide mold, and has an opening 45 that allows the slide mold to be removed. In the base material 31, it is provided in the location which becomes the opening direction side of the opening part 45 rather than the clip seat 42. FIG.

  When the clip seat 42 is formed using a slide mold, it is difficult to form a reinforcing member such as the rib 34 at a location on the base 31 that is on the opening direction side of the opening 45 (the mold release direction side of the slide mold). This is because if the rib 34 is provided at such a location, it interferes with the rib 34 when the slide mold is removed.

  Therefore, in the present embodiment, the protrusions 60 </ b> A are provided at locations on the base material 31 that are closer to the opening direction side of the opening 45 than the clip seat 42. Thereby, in the base material 31, the deformation | transformation of the location where it is difficult to provide the rib 34 (location where rigidity tends to be low) can be effectively suppressed.

<Embodiment 2>
Next, Embodiment 2 of the present invention will be described with reference to FIG. In this embodiment, the formation location of the protrusion 60 is different from that of the above embodiment. In the pillar garnish 130 of the present embodiment, the protrusions 60 are formed at the same positions as the ribs 34 in the longitudinal direction of the base material 31.

  In the base material 31, the portion where the rib 34 is formed is a portion that is relatively rigid and difficult to deform.
