Description

  The present invention belongs to a technical field related to an interior structure of a vehicle including an interior member such as a coat hook and an occupant protection means such as a curtain airbag.

  2. Description of the Related Art Conventionally, there has been known a curtain airbag device that inflates and deploys an airbag (curtain airbag) so as to cover a window of the vehicle when the vehicle side-impacts or rolls over. In this curtain airbag device, the airbag is housed in a folded state between the inner panel of the roof side rail of the vehicle and the roof trim. When the airbag is deployed, the roof trim is applied by the deployment pressure. By pressing and deforming to the passenger compartment side, the engagement between the end of the roof trim and the garnish provided around the pillar trim and the window is released, so that the airbag is inflated and deployed toward the passenger compartment from the gap therebetween It has become.

In a vehicle equipped with the curtain airbag device as described above, a pillar garnish is arranged along the upper part of the side window frame, and a hook for a hanger (coat hook) is provided on the pillar garnish. (See, for example, Patent Document 1). In this case, a hanger casing is integrally formed on the pillar garnish, and this casing is attached to the upper part of the frame of the side window. The pillar garnish is surely held when the action is applied.
JP 2003-226199 A

  In the above-mentioned conventional example, the hook for the hanger is provided on a hard garnish that hardly deforms when the airbag is deployed. Therefore, there is no problem that the hook is detached when the airbag is deployed.

  On the other hand, it is conceivable that the interior member such as the hook is attached not to a hard garnish but to a soft roof trim that deforms when the airbag is deployed, from the viewpoint of the arrangement space. In this case, in order to secure the mounting strength of the interior member to some extent, the interior member is attached to the vehicle body outside the roof trim via the roof trim. That is, a mounting base is disposed between the roof trim and the vehicle body, a clip or the like is provided on the surface of the mounting base on the vehicle body, and the mounting base is engaged and fixed to the vehicle body via the clip or the like. Further, a clip or the like is also provided on the surface of the interior trim member installed closer to the vehicle compartment side on the roof trim side, and the interior member is engaged and fixed to the mounting base via the clip or the like. The roof trim is formed with a through-hole through which a clip or the like provided on the surface of the interior member on the roof trim side is inserted, and the through-hole is trimmed so that the periphery of the through-hole is not visible to the passenger. Cover with side surface. By doing so, the interior member can be fixed to the vehicle body with a mounting strength that does not come off even if the occupant applies force, and the through hole is not visible to the occupant, and the appearance can be improved. .

  However, in the method for attaching the interior member as described above, when the roof trim is pressed to the vehicle compartment side by the airbag, the interior member is pressed to the vehicle compartment side via the roof trim, and the interior member is attached to the interior. The possibility that the engagement with the base is released is increased. When the engagement between the interior member and the mounting base is released as described above, there is a problem that the interior member comes off from the mounting base (that is, the roof trim) and flies.

  The present invention has been made in view of such a point, and the object of the present invention is to attach an interior member to a roof trim that is pressed and deformed toward the passenger compartment by an occupant protection means such as an airbag. By devising the configuration, the occupant protection means tries to prevent the interior member from flying off the roof trim when the roof trim is pressed and deformed.

  In order to achieve the above object, according to the present invention, when the occupant protection means presses and deforms the roof trim, the interior member is attached and fixed to the attachment base body of the attachment base via the attachment portion. The engagement with the vehicle body of the engaging portion of the base portion is released.

Specifically, in the invention of claim 1, the interior structure of the vehicle is targeted.
A roof trim covering the vehicle compartment side of the vehicle roof,
A vehicle body disposed on the vehicle outer side than the roof trim,
An attachment base body disposed between the roof trim and the vehicle body; and an engagement portion provided on a surface of the attachment base body on the vehicle body side and engaged with the vehicle body, the vehicle body of the engagement portion An attachment base fixedly attached to the vehicle body by engagement with
The interior surface of the interior member that covers the through hole provided in the roof trim, the interior surface of the interior member body that is installed on the vehicle compartment side of the roof trim, An interior member that has an attachment portion inserted through the through hole, and is attached and fixed to the attachment base body through the attachment portion,
An occupant protection means that is disposed between the roof trim and the vehicle body and presses and deforms the roof trim toward the passenger compartment when a vehicle collides,
When the occupant protection means presses and deforms the roof trim, the engagement of the engagement portion with the vehicle body is released in a state where the interior member is attached and fixed to the attachment base main body via the attachment portion. It shall be comprised so that it may be carried out.

  With the above configuration, even when the occupant protection means presses and deforms the roof trim, the interior member is fixedly attached to the attachment base body via the attachment portion, so that the interior member flies away from the roof trim. There is no such thing. On the other hand, since the engagement of the engagement portion with the vehicle body is released, the roof trim is pressed by the occupant protection means, and is deformed together with the interior member and the mounting base to the passenger compartment side. If it is a curtain airbag, the end of the roof trim and the pillar trim etc. are disengaged by deformation of the roof trim, and the curtain airbag is securely deployed from the gap between them into the vehicle interior. It will be possible to protect the passengers. Further, when the occupant protection means is an energy absorbing member such as a pad, the energy absorbing member moves to the passenger compartment side and deforms the roof trim by the vehicle body entering the passenger compartment side. An absorbing member is interposed between the head of the occupant and the vehicle body to protect the occupant.

  According to a second aspect of the present invention, in the first aspect of the invention, when the occupant protection means presses and deforms the roof trim, the disengagement promotion for accelerating the disengagement of the engagement portion from the vehicle body. A disengagement promoting member that is moved by receiving a pressing force from the occupant protection means, and that engages the engagement portion with the vehicle body as the pressure receiving movement portion moves. It has a pressing part which presses the above-mentioned attachment base part main body so that it may cancel.

  As a result, the pressing force that presses the roof trim of the occupant protection means is converted into a pressing force that presses the mounting base body to promote the release of the engagement of the engagement portion with respect to the vehicle body. The engagement can be released early. As a result, before the attachment portion of the interior member is detached from the attachment base body, it is possible to reliably release the engagement of the engagement portion with respect to the vehicle body, and reliably prevent the interior member from being detached from the attachment base body. Can do. Even if the engagement portion is configured not to easily come off the vehicle body, the engagement can be easily released by the engagement release promoting member. If the engaging portion is configured not to easily come off from the vehicle body, the mounting strength of the interior member can be improved, and the engagement portion does not come off the vehicle body even when a passenger applies a force to the interior member. It can be fixed securely.

  According to a third aspect of the present invention, in the second aspect of the present invention, a portion where the through hole is formed in the roof trim and a portion where the engaging portion of the vehicle body engages extend in the vertical direction, and the mounting base body Is located above the occupant protection means, and at least a part of the pressure receiving moving portion of the disengagement promoting member is located between the attachment base body and the occupant protection means.

  As a result, it is possible to prevent the pressing force of the occupant protection means from directly acting on the mounting base main body, thereby preventing a large impact force from acting on the mounting base main body and damaging it. As a result, it is possible to prevent the interior member from being detached from the attachment base body due to such damage. Further, by providing the mounting base body on the upper side of the occupant protection means, the mounting base body can be prevented from interfering with the operation of the occupant protection means at the time of a vehicle collision.

  According to a fourth aspect of the present invention, in the third aspect of the present invention, the engaging portion is constituted by a clip portion that is inserted into and engaged with an engaging hole formed in the vehicle body, and the clip portion is formed on the clip portion. The engaging projection is provided at least on the upper and lower portions and engaged with the engaging hole, and the engaging portion is released from the engaging portion with respect to the clip portion. When the disengagement force is applied in the axial direction of the joint hole, the lower engagement protrusion is smaller than the upper engagement protrusion with the disengagement force. It is assumed that the engagement is released.

  As a result, the lower engagement protrusion is more easily disengaged from the engagement hole than the upper engagement protrusion, and the disengagement of the clip portion (engagement portion) from the vehicle body is further facilitated. can do. That is, since the attachment base body is located above the occupant protection means, the portion where the roof trim is pressed toward the passenger compartment by the occupant protection means is located below the through hole. For this reason, in the mounting base main body, a large force (force for releasing the engagement of the clip portion with respect to the vehicle body) acts on the lower side than the upper side. As a result, the attachment base main body is inclined with respect to a direction perpendicular to the surface of the vehicle body on the passenger compartment side, and the clip portion is detached from the vehicle body. At this time, the lower engaging protrusion is configured to be more easily disengaged from the engaging hole than the upper engaging protrusion, so that the clip portion corresponds to the inclination of the mounting base body. It will come off smoothly from the joint hole.

  According to a fifth aspect of the present invention, in the invention according to any one of the second to fourth aspects, the pressing portion of the disengagement promoting member is sandwiched between the vehicle body side surface of the mounting base body and the vehicle body. It shall be.

  By doing so, it is possible to release the engagement of the engaging portion with respect to the vehicle body quickly and reliably with a simple configuration.

  As described above, according to the vehicle interior structure of the present invention, when the occupant protection means presses and deforms the roof trim, the interior member is attached and fixed to the attachment base body of the attachment base via the attachment portion. With this configuration, the engagement between the engagement portion of the mounting base and the vehicle body is released, so that even if the occupant protection means presses and deforms the roof trim, the interior member will come off the roof trim and fly. Can be prevented, and the occupant can be reliably protected by the occupant protection means.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(Embodiment 1)
FIG. 1 shows a main part of a vehicle (automobile) to which an interior structure according to Embodiment 1 of the present invention is applied. In the figure, 1 is a front side window located beside the driver's seat, 2 is a rear side window located beside the rear seat, 3 is a front pillar, 4 is a center pillar, and 5 is a rear pillar.

  The vehicle is equipped with a curtain airbag device, and the curtain airbag device is configured to cover the front side window 1 and the rear side window 2 of the vehicle.

  Specifically, the curtain airbag device includes a curtain airbag 21 (occupant protection means) that is inflated by injecting gas, and an inflator (not shown) that supplies gas to the curtain airbag 21. . As shown in FIG. 2, the curtain airbag 21 is folded in a bellows shape, and is accommodated along a roof side rail 11 (vehicle body) that extends in the vehicle front-rear direction above the front side window 1 and the rear side window 2. ing. Then, the curtain airbag 21 is deployed in a curtain shape so as to simultaneously cover the front side window 1 and the rear side window 2 by the expansion caused by the gas injection. The curtain airbag 21 is covered with a sheet-like member (not shown) such as paper that is easily torn during inflation and deployment so that the folded state is maintained.

  The inflator operates when the vehicle is in a predetermined state, generates gas, and supplies the gas to the curtain airbag 21. The predetermined state is, for example, when a vehicle collision (especially a side collision) is predicted, when the vehicle collision is detected, or when the vehicle rollover is determined. And a controller for operating the inflator 21 to determine the occurrence of these states by receiving the outputs of the sensors.

  The roof side rail 11 is composed of an inner panel 11a, an outer panel 11b, and a reinforcement 11c, and the vehicle roof portion has a vehicle width direction end portion in a state in which both end portions thereof are overlapped with each other. It arrange | positions so that it may extend in the front-back direction.

  In FIG. 2, 12 is a roof panel, 13 is a window glass provided on the rear side window 2, 14 is a seal member, and 15 is a weather strip provided on the upper edge of the rear side window 2. The weather strip 15 is also disposed on the upper edge of the front side window 1.

  The upper edge of the curtain airbag 21 is fixed to the inner panel 11a of the roof side rail 11 at a plurality of locations by fixing members 22 such as clips. The fixing position of the curtain airbag 21 by the fixing member 22 is in a position where it does not overlap with a pressure receiving moving portion 25a of an engagement release promoting member 25 described later in a side view of the vehicle (see FIG. 5).

  The passenger compartment side of the folded curtain airbag 21 is covered with a roof trim 18 that covers the passenger compartment side of the vehicle roof portion. The roof trim 18 is made of a soft material such as foamable urethane resin that can be deformed by the inflation and deployment pressure of the curtain airbag 21. In the vehicle width direction, the height of the roof trim 18 differs between the central portion 18a and the end portion 18b, and the central portion 18a is higher than the end portion 18c. For this reason, although the center part 18a and the edge part 18b are extended horizontally, the boundary part 18c between the center part 18a and the edge part 18b is a vehicle width toward the up-down direction (in this embodiment, a lower side). It extends in an oblique vertical direction inclined outward in the direction). The central portion 18a is arranged so as to be substantially along with a gap with respect to the roof panel 12, and the end portion 18b and the boundary portion 18c are substantially in a state with a gap with respect to the inner panel 11a of the roof side rail 11. It is arranged along. The folded curtain airbag 21 is positioned between the boundary portion 18c and the inner panel 11a.

  The edge of the roof trim 18 in the vehicle width direction is detachably engaged with the weather strip 15, and when the curtain airbag 21 is inflated and deployed, the engagement is released by the inflation and deployment pressure. . That is, when the curtain airbag 21 is inflated and deployed, the end portion 18b and the boundary portion 18c of the roof trim 18 are pressed and deformed toward the passenger compartment by the curtain airbag 21 (the end portion 18b of the roof trim 18 is directed downward). The boundary portion 18c is pressed and deformed inward in the vehicle width direction). As a result, the edge of the roof trim 18 is detached from the weather strip 15. As a result, a gap is formed between the roof trim 18 and the weather strip 15, and the curtain airbag 21 is deployed in the vehicle interior from this gap. The edge of the roof trim 18 in the vehicle width direction is detachably engaged with the pillar trim 7 (see FIG. 1) constituting the surface of the center pillar 4 on the passenger compartment side at the center pillar 4. When the curtain airbag 21 is inflated and deployed and the end portion 18b and the boundary portion 18c of the roof trim 18 are pressed and deformed toward the passenger compartment, the edge engaged with the pillar trim 7 is detached from the pillar trim 7. It is like that. The pillar trim 7 is made of a synthetic resin harder than the roof trim 18 (for example, polypropylene, thermoplastic olefin (TPO), or the like).

  A coat hook 31 as an interior member is provided above the boundary portion 18c of the roof trim 18 above the rear side window 2 (a position above the folded curtain airbag 21). The coat hook 31 is fixedly attached to the inner panel 11 a of the roof side rail 11 via the mounting base 32.

  Specifically, as shown in FIG. 2, the mounting base 32 is mounted on a mounting base main body 32a disposed between the roof trim 18 and the inner panel 11a, and on the surface of the mounting base main body 32a on the inner panel 11a side. And an engaging portion 32b that engages with the inner panel 11a and is fixedly attached to the inner panel 11a by engagement of the engaging portion 32b with the inner panel 11a. The portion of the inner panel 11a that engages with the engaging portion 32b extends in the vertical direction (in this embodiment, an oblique vertical direction inclined outward in the vehicle width direction toward the lower side), like the roof trim 18. The vehicle body engagement hole 11d penetrates the inner panel 11a in the thickness direction (direction perpendicular to the surface of the inner panel 11a on the passenger compartment side). The vehicle body engagement hole 11d includes a clip portion. The engaging portion 32b is inserted and engaged.

  The engagement portion 32b (clip portion) has engagement protrusions 32c and 32d that are provided on the upper and lower portions of the clip portion and engage with the vehicle body engagement hole 11d. As shown in FIG. 3, the lower engaging projection 32c has a proximal end connected to the distal end portion of the clip portion and extends from the proximal end toward the mounting base main body 32a, and the distal end is engaged with the vehicle body. It is composed of a cantilevered flexible portion that can be bent in a direction perpendicular to the axis of the joint hole 11d. A base end side inclined surface 32e is formed at the base end side portion of the flexible portion and is inclined toward the tip side of the flexible portion away from the axis of the vehicle body engagement hole 11d. A distal-side inclined surface 32f that approaches the axial center of the vehicle body engagement hole 11d from the distal end of the proximal-side inclined surface 32e toward the distal end side of the flexible portion is formed in the distal-end side portion of the front-end side. Further, as shown in FIG. 4, the upper engaging protrusion 32d is configured by a flexible portion similar to the engaging protrusion 32c, and the proximal end portion of the flexible portion includes the flexible portion. A proximal-side inclined surface 32g that is inclined toward the distal side toward the side away from the axis of the vehicle body engagement hole 11d is formed, and a distal-side portion of the flexible portion is formed from the distal end of the proximal-side inclined surface 32g. A tip side inclined surface 32h that approaches the axis of the vehicle body engagement hole 11d is formed toward the tip side of the flexible portion.

  When engaging the engaging portion 32b (clip portion) with the vehicle body engaging hole 11d, the engaging portion 32b is inserted into the vehicle body engaging hole 11d by moving along the axis. At this time, the base end side inclined surfaces 32e and 32g abut against the opening edge of the vehicle body engagement hole 11d on the vehicle compartment side, so that the engagement protrusions 32c and 32d approach the axis of the vehicle body engagement hole 11d. As a result, the engagement protrusions 32c and 32d pass through the vehicle body engagement hole 11d and move outward in the vehicle width direction of the vehicle body engagement hole 11d, and after passing through the engagement protrusions 32c and 32d, In order to return to this state, the front end side inclined surfaces 32f and 32h of the engagement protrusions 32c and 32d engage with the opening edge of the vehicle body engagement hole 11d on the outer side in the vehicle width direction. At this time, the surface on the inner panel 11a side of the mounting base body 32a contacts the surface on the vehicle interior side of the inner panel 11a (more specifically, the vehicle interior of the inner panel 11a via the disengagement promoting member 25 described later). Touch the side surface). In the engaged state, an occupant of the vehicle applies a disengagement force to the engaging portion 32b in the axial direction of the vehicle body engaging hole 11d so as to release the engagement with the vehicle body engaging hole 11d. However, the engagement is not released. That is, the engagement protrusions 32c and 32d cannot be bent so as to approach the axial center of the vehicle body engagement hole 11d with the above-described engagement release force that is less than or equal to a predetermined value that can be output by a person. In addition, you may make it provide the engagement protrusions similar to the engagement protrusions 32c and 32d also in parts other than the upper part and lower part of the said clip part.

  On the other hand, when the curtain airbag 21 is deployed, the engagement of the engagement portion 32b with the vehicle body engagement hole 11d is released as will be described later. Here, when the disengagement force is applied to the engagement portion 32b, the lower engagement projection 32c is smaller than the upper engagement projection 32d with the above engagement release force. The engagement with the joint hole 11d is released. In order to do this, for example, the lower engagement protrusion 32c is thinner than the upper engagement protrusion 32d so that it can be bent more easily, or the tip of the lower engagement protrusion 32c can be bent. If the inclination angle of the side inclined surface 32f with respect to the axis of the vehicle body engagement hole 11d is made smaller than the inclination angle of the upper side engagement protrusion 32d with respect to the axis of the vehicle body engagement hole 11d of the front end side inclined surface 32h. Good. With this configuration, the lower engagement protrusion 32c is more easily disengaged from the vehicle body engagement hole 11d than the upper engagement protrusion 32d, and the engagement part 32b is located with respect to the axis of the vehicle body engagement hole 11d. It is in an oblique state (that is, a state in which the lower part of the surface of the mounting base body 32a on the inner panel 11a side is far away from the surface of the inner panel 11a on the side of the passenger compartment), and is disengaged from the vehicle body engagement hole 11d. . Since the engaging portion 32b is thus detached from the vehicle body engaging hole 11d in an oblique state, the tip of the engaging portion 32b is cut obliquely so as not to be twisted into the vehicle body engaging hole 11d.

  The mounting base body 32a is located above the folded curtain airbag 21, and extends from the vehicle compartment side surface of the inner panel 11a toward the roof trim 18 (vehicle compartment side). The boundary 18c of the roof trim 18 is in contact with the surface of the mounting base body 32a on the roof trim 18 side. A base engaging hole 32i is formed on the surface of the roof trim 18 so that a mounting portion 31b, which will be described later, provided on the coat hook 31 is engaged. The base engaging hole in the boundary portion 18c of the roof trim 18 is formed. A through hole 18d that penetrates in the thickness direction of the roof trim 18 is formed in a portion facing the opening 32i.

  The coat hook 31 is installed closer to the passenger compartment than the roof trim 18 and the surface of the roof trim 18 side covers the through hole 18d, and the roof of the hook body 31a. An attachment portion 31b provided on the surface on the trim 18 side and inserted through the through hole 18d is attached and fixed to the attachment base portion main body 32a via the attachment portion 31b. In the present embodiment, the attachment portion 31b is composed of an egg-shaped clip portion (partially perforated so as to be deformable) inserted and engaged with the base engagement hole 32i. The coat hook 31 is attached and fixed to the attachment base body 32a by the engagement of the attachment portion 31b with the base engagement hole 32i. Thus, the coat hook 31 is attached and fixed to the inner panel 11 a via the attachment base 32.

  The surface of the hook body 31a on the roof trim 18 side has an outer diameter larger than that of the through hole 18d, and covers the through hole 18d while being in contact with the roof trim 18. Thereby, the through-hole 18d in the roof trim 18 and the periphery of the through-hole 18d are not visible to the occupant, and the appearance is improved.

  When the curtain airbag 21 of the curtain airbag device is inflated and deployed by supplying gas from the inflator, the end portion 18b of the roof trim 18 and the boundary are caused by the inflation and deployment pressure of the curtain airbag 21 as described above. The portion 18c is pressed and deformed toward the passenger compartment. At this time, since the coat hook 31 is pressed toward the passenger compartment by the roof trim 18, the engagement between the attachment portion 31b and the base engagement hole 32i of the attachment base main body 32a, and the engagement portion 32b and the inner panel 11a. At least one of the engagement with the vehicle body engagement hole 11d is about to be released.

  Here, if at least one of the two engagements is not released, the roof trim 18 cannot be greatly deformed. For this reason, the engagement between the roof trim 18 and the weather strip 15 is not released or released. Even so, a sufficient gap is not formed between the roof trim 18 and the weather strip 15, which affects the deployability of the curtain airbag 21. On the other hand, when at least the engagement between the attachment portion 31b and the base engagement hole 32i is released, there is a problem that the coat hook 31 is disengaged from the roof trim 18 and flies. Therefore, in the present embodiment, when the curtain airbag 21 presses and deforms the roof trim 18, the coat hook 31 is attached and fixed to the attachment base body 32a via the attachment portion 31b. The engagement with the vehicle body engagement hole 11d is configured to be released.

  Specifically, the disengagement force in the axial direction of the vehicle body engagement hole 11d with respect to the vehicle body engagement hole 11d of the engagement portion 32b is used as the base engagement hole 32i of the attachment portion 31b with respect to the base engagement hole 32i. The engagement force is made smaller than the axial disengagement force and promotes the disengagement of the engagement portion 32b from the vehicle body engagement hole 11d when the curtain airbag 21 presses and deforms the roof trim 18. A combination release promoting member 25 is provided. The disengagement promoting member 25 includes a pressure receiving moving portion 25a that moves by receiving a pressing force from the curtain airbag 21 at the time of deployment, and a vehicle body engagement of the engaging portion 32b as the pressure receiving moving portion 25a moves. It consists of a board | plate material which has the press part 25b which presses the said attachment base main body 32a so that engagement with 11d of joint holes may be cancelled | released.

  The disengagement promoting member 25 has a base end portion (upper end portion) fixed to the inner panel 11a by a fixing member 26 such as a clip and extends downward from the base end portion, and a front end portion (lower end portion) of the vehicle. The cantilever is configured to be able to bend in the width direction. And the said pressure receiving movement part 25a is provided in the front-end | tip part side of the engagement release promotion member 25, and the said press part 25b is provided in the base end part side. The pressure receiving moving part 25a is disposed so as to cover the passenger compartment side (in the vehicle width direction) and the upper side of the folded curtain airbag 21, and the pressing part 25b is connected to the pressure receiving moving part 25a and the inner panel 11a. The inner base 11a of the mounting base body 32a is sandwiched between the inner panel 11a side and the inner panel 11a of the inner panel 11a. Thereby, the surface of the attachment base body 32a on the inner panel 11a side is in contact with the inner panel 11a via the pressing portion 25b of the engagement release promoting member 25. The pressing portion 25b is formed with an insertion hole 25c through which the engaging portion 32b is inserted.

  When the curtain airbag 21 is inflated and deployed, the pressure-receiving / moving portion 25a is moved by being pushed upward on the vehicle compartment side by the inflation and deployment pressure. Along with this movement, the pressing portion 25b presses the attachment base main body 32a toward the passenger compartment side and upward. In addition, immediately after the curtain airbag 21 moves the pressure receiving moving portion 25a until it contacts the roof trim 18, the end portion 18b and the boundary portion 18c of the roof trim 18 are moved to the vehicle compartment while pressing the pressure receiving moving portion 25a. The portion where the roof trim 18 is pressed is positioned below the through hole 18d (coat hook 31). For this reason, a large force (a force for releasing the engagement of the engagement portion 32b with respect to the vehicle body engagement hole 11d) acts on the lower side of the attachment base body 32a than on the upper side. As a result, when the mounting base body 32a is inclined so that the lower part of the surface of the mounting base body 32a on the inner panel 11a side is far away from the surface of the inner panel 11a on the passenger compartment side, the engaging base body 32a is engaged. The part 32b comes off from the vehicle body engagement hole 11d. At this time, as described above, in the engaging portion 32b, the lower engaging protrusion 32c is more easily detached from the vehicle body engaging hole 11d than the upper engaging protrusion 32d, and the pressing portion 25b is attached. Since the base main body 32a is pressed toward the vehicle compartment side and upward, the engaging portion 32b is smoothly disengaged from the vehicle body engaging hole 11d corresponding to the inclination of the mounting base main body 32a.

  The portion of the pressure receiving moving portion 25a located above the curtain airbag 21 is located between the attachment base main body 32a and the curtain airbag 21, and thereby the pressing force of the curtain airbag 25 is increased. Is prevented from acting directly on the mounting base main body 32a, thereby preventing the mounting base main body 32a from being broken, and further preventing the engagement between the mounting portion 31b and the base engaging hole 32i from being broken. Yes.

  In addition, the portion of the pressure receiving and moving portion 25a located on the passenger compartment side of the curtain airbag 21 prevents the occupant's head from colliding with the inner panel 11a at the time of a light vehicle collision where the curtain airbag 21 is not deployed. To play a role. That is, when the occupant's head moves outward in the vehicle width direction during a light vehicle collision, the occupant's head collides with the pressure receiving moving portion 25 a via the roof trim 18. If a gap is formed between the pressure receiving moving part 25a and the folded curtain airbag 21 in advance, the pressure receiving moving part 25a that has collided with the head of the occupant moves to the outside in the vehicle width direction. Absorb energy. Even if the pressure receiving moving part 25a cannot absorb the collision energy and the pressure receiving moving part 25a collides with the folded curtain airbag 21, the collision air bag 21 and the pressure receiving moving part 25a generate the collision energy. It can absorb and it can prevent that a passenger | crew's head collides with the inner panel 11a. In addition, the part located in the vehicle compartment side of the curtain airbag 21 in the pressure receiving moving part 25a is not necessarily required, and all the parts of the pressure receiving moving part 25a are located between the attachment base main body 32a and the curtain airbag 21. You may comprise. Even in this case, the folded curtain airbag 21 can prevent the occupant's head from colliding with the inner panel 11a during a light vehicle collision.

  When the curtain airbag 21 is inflated and deployed, the curtain airbag 21 first comes into contact with the pressure receiving moving portion 25a of the disengagement promoting member 25 and presses the pressure receiving moving portion 25a on the vehicle compartment side and upward. Immediately after the pressure receiving moving portion 25a is moved until it contacts the roof trim 18, the end 18b and the boundary portion 18c of the roof trim 18 are moved to the vehicle compartment while the pressure receiving moving portion 25a is further pushed to the vehicle compartment side. Press and deform to the side. At this time, the pressing portion 25b presses the attachment base main body 32a toward the passenger compartment side and upward as the pressure receiving moving portion 25a moves. The coat hook 31 and the attachment base 32 are engaged with the attachment portion 31b and the base engagement hole 32i of the attachment base body 32a, and between the engagement portion 32b and the vehicle body engagement hole 11d of the inner panel 11a. However, the force of releasing the engagement of the vehicle body engagement hole 11d with respect to the vehicle body engagement hole 11d of the engagement portion 32b is applied to the base engagement hole 32i of the attachment portion 31b with respect to the base engagement hole 32i. The engagement release member 25 is smaller than the engagement release force in the axial direction of the joint hole 32i, and the engagement release promotion member 25 presses the attachment base main body 32a to the vehicle compartment side and to the upper side. Since the disengagement between the vehicle body engagement hole 11d and the vehicle body engagement hole 11d is promoted, the vehicle body engagement hole 11d of the engagement portion 32b is fixed in a state where the coat hook 31 is fixedly attached to the attachment base body 32a via the attachment portion 31b. Is disengaged (see FIG. 6). ).

  Then, due to the deformation of the roof trim 18, the engagement between the roof trim 18 and the weather strip 15 (and the engagement between the roof trim 18 and the pillar trim 7) is released, and the curtain airbag 21 is inflated and deployed in the vehicle interior. The front side window 1 and the rear side window 2 are covered.

  Therefore, in the present embodiment, when the curtain airbag 21 is inflated and deployed and the roof trim 18 is pressed and deformed, the coat hook 31 is attached and fixed to the attachment base body 32a via the attachment portion 31b. Since the engaging portion 32b is disengaged from the vehicle body engaging hole 11d, the coat hook 31 does not fly away from the roof trim 18. On the other hand, since the engaging portion 32b is disengaged from the vehicle body engaging hole 11d, the roof trim 18 is pressed by the deployed curtain airbag 21 and deformed together with the coat hook 31 and the mounting base 32 to the vehicle interior side, and the roof trim 18, the engagement between the roof trim 18, the weather strip 15, and the pillar trim 7 is released, and the curtain airbag 21 is deployed in the vehicle interior from the gap therebetween. As a result, the occupant can be reliably protected.

  In the present embodiment, when the curtain airbag 21 presses and deforms the roof trim 18, the engagement release promoting member 25 promotes the engagement of the engagement portion 32b with the vehicle body engagement hole 11d. The engagement can be released early and reliably, and the coat hook 31 can be reliably prevented from being detached from the attachment base body 32a.

  Furthermore, since the fixing portion of the curtain airbag 21 by the fixing member 22 is in a position not overlapping the pressure receiving moving portion 25a of the engagement release promoting member 25 in a side view of the vehicle, the deployment of the curtain airbag 21 is fixed to the fixing member. Thus, the pressure receiving moving portion 25a can be pressed early without being obstructed by the contact 22, thereby disengaging the engaging portion 32b from the vehicle body engaging hole 11d even earlier.

  Further, since the mounting base 32 is fixedly attached to the inner panel 11a via the engaging portion 32b formed of a clip portion, the mounting base 32 is fixed and fixed without using means such as screwing or welding. It is possible to improve the mounting workability.

(Embodiment 2)
FIG. 7 shows a second embodiment of the present invention (in the following embodiments, the same parts as those in FIG. 2 are denoted by the same reference numerals and detailed description thereof is omitted), and the disengagement promoting member 25 is shown. The configuration is different from that of the first embodiment.

  In other words, in the present embodiment, the pressure receiving moving portion 25a of the disengagement promoting member 25 is located on the outer side in the vehicle width direction of the folded curtain airbag 21 and is substantially in contact with the curtain airbag 21. The disengagement promoting member 25 is fixed to the inner panel 11a by a fixing member 26 at a portion between the pressure receiving moving portion 25a and the pressing portion 25b. A ring-shaped elastic member 27 is disposed between the head portion 26 a of the fixing member 26 and the disengagement promoting member 25. Further, the portion of the inner panel 11a that faces the pressure receiving moving part 25a is recessed outward in the vehicle width direction so that a gap is formed between the inner panel 11a and the pressure receiving moving part 25a. As a result, the pressure receiving moving portion 25a can move outward in the vehicle width direction, and along with this movement, the pressing portion 25b compresses and deforms the upper portion of the elastic member 27 so that the vehicle moves like a seesaw. It can be moved to the room side.

  When the curtain airbag 21 is inflated and deployed, the pressure-receiving / moving portion 25a is moved outwardly in the vehicle width direction by the inflated and deployed pressure (see the state indicated by the two-dot chain line in FIG. 7). Along with this movement, the pressing portion 25b presses the attachment base body 32a toward the passenger compartment side in an attempt to move toward the passenger compartment side. As a result, the disengagement promoting member 25 is similar to the first embodiment when the curtain airbag 21 press-deforms the roof trim 18 and the engagement portion 32b and the vehicle body engagement hole 11d of the inner panel 11a. The release of the engagement is promoted. In the present embodiment, unlike the first embodiment, the lower engagement protrusion is applied when an engagement release force is applied to the engagement portion 32b in the axial direction of the vehicle body engagement hole 11d. 32c and the upper engagement protrusion 32d are disengaged from the vehicle body engagement hole 11d with the same disengagement force.

  Accordingly, also in the present embodiment, as in the first embodiment, when the curtain airbag 21 is inflated and deployed and the roof trim 18 is pressed and deformed, the coat hook 31 is attached to the attachment base body 32a via the attachment portion 31b. The engagement of the engagement portion 32b with respect to the vehicle body engagement hole 11d is released in a state of being fixedly attached to the vehicle body, so that the coat hook 31 can be prevented from flying off the roof trim 18.

  In the first and second embodiments, the disengagement force in the axial direction of the vehicle body engagement hole 11d with respect to the vehicle body engagement hole 11d of the engagement portion 32b is used as the base portion with respect to the base engagement hole 32i of the attachment portion 31b. Although the engagement release force is smaller than the engagement release force in the axial direction of the engagement hole 32i, the magnitude relationship between the two engagement release forces may be reversed. What is necessary is just to set in consideration of the pressing force with respect to the attachment base part main body 32a of the press part 25b of the member 25 (the same also in Embodiment 3 mentioned later).

  Further, the disengagement force in the axial direction of the vehicle body engagement hole 11d with respect to the vehicle body engagement hole 11d of the engagement portion 32b is the axial direction of the base engagement hole 32i with respect to the base engagement hole 32i of the attachment portion 31b. In the case where the disengagement force is considerably smaller than the disengagement force, the disengagement promoting member 25 need not be provided. For example, when the mounting portion 31b is formed of a screw portion, the engagement releasing force in the axial direction of the base engaging hole 32i with respect to the base engaging hole 32i of the mounting portion 31b becomes very large. Even if the release promoting member 25 is not provided, the engagement of the engagement portion 32b with the vehicle body engagement hole 11d can be reliably released (the same applies to the third embodiment described later).

(Embodiment 3)
FIG. 8 shows Embodiment 3 of the present invention, in which the present invention is applied to an opening for blowing conditioned air into the vehicle interior in the air conditioning duct 51.

  That is, in the present embodiment, the roof trim 18 is provided with an opening member 41 as an interior member for improving the appearance of the opening, instead of the coat hook 31 in the first and second embodiments. . The opening member 41 is attached and fixed to the inner panel 11a (vehicle body engagement hole 11d) of the roof side rail 11 via the attachment base 42.

  Similar to the mounting base 32 in the first and second embodiments, the mounting base 42 includes a mounting base main body 42a disposed between the roof trim 18 and the inner panel 11a, and the mounting base main body 42a on the inner panel 11a side. An engaging portion 42b is provided on the surface and engages with the inner panel 11a, and is fixedly attached to the inner panel 11a by engagement of the engaging portion 42b with the inner panel 11a.

  The mounting base body 42a is disposed so as to surround the end opening of the air conditioning duct 51 or the vicinity of the vicinity thereof (excluding the portion through which the air conditioning duct 51 passes). Further, a plurality of the engaging portions 42b are provided (correspondingly, a plurality of vehicle body engaging holes 11d are also provided), and the configuration thereof is the same as that of the engaging portion 31b in the first embodiment.

  The opening member 41 is provided on the outer peripheral portion of the opening member main body 41a (corresponding to the interior member main body) installed on the vehicle compartment side of the roof trim 18 and the surface of the opening member main body 41a on the roof trim 18 side; And a base engaging hole provided on a surface of the mounting base body 42a on the roof trim 18 side through the mounting portion 41b. It is fixedly attached to 42i. A plurality of mounting portions 41b are provided (correspondingly, a plurality of through holes 18d and base engaging holes 42i are also provided), and the configuration thereof is the same as that of the mounting portion 31b in the first embodiment. The plurality of through holes 18d are covered with the surface of the opening member main body 41a on the roof trim 18 side.

  At the center of the surface of the opening member main body 41a on the roof trim 18 side, a protruding portion 41c having a tip inserted into the end opening of the air conditioning duct 51 through a duct opening hole 18e provided in the roof trim 18 is formed. An air passage 41d that penetrates the opening member main body 41a and opens to the surface of the opening member main body 41a is formed in the center of the projecting portion 41c. The blown air-conditioned air is guided to the vehicle interior through the air passage 41d. Note that a louver (not shown) capable of changing the blowing direction of the conditioned air is disposed at the end of the air passage 41d on the passenger compartment side. Further, the periphery of the duct opening hole 18e is covered with the surface of the opening member main body 41a on the roof trim 18 side so that it cannot be seen by the passenger.

  Also in the present embodiment, as in the first and second embodiments, when the curtain airbag 21 presses and deforms the roof trim 18, the opening member 41 is attached and fixed to the attachment base main body 42a via the attachment portion 41b. In this state, the engagement portion 42b is disengaged from the vehicle body engagement hole 11d. That is, the sum of the disengagement forces in the axial direction of the vehicle body engagement holes 11d with respect to the vehicle body engagement holes 11d of all the engagement portions 42b is the base engagement with the base engagement holes 42i of all the attachment portions 41b. An engagement release facilitating member 25 is provided to make the engagement release force in the axial direction of the hole 42i smaller than the total and to promote the release of the engagement of the engagement portion 42b from the vehicle body engagement hole 11d. The configuration of the disengagement promoting member 25 is the same as that of the first embodiment.

  Therefore, also in the present embodiment, as in the first and second embodiments, when the curtain airbag 21 is inflated and deployed and the roof trim 18 is pressed and deformed, the opening member 41 is attached to the attachment base portion via the attachment portion 41b. In a state of being fixedly attached to the main body 42a, the engagement of the engagement portion 42b with the vehicle body engagement hole 11d is released, and thus the opening member 41 can be prevented from flying off the roof trim 18.

  In the first to third embodiments, an example of the curtain airbag 21 is shown as the occupant protection means. However, the occupant protection means is disposed between the roof trim 18 and the vehicle body, and the roof trim 18 is disposed on the vehicle compartment side at the time of a vehicle collision. Any material may be used as long as it can be pressed and deformed. For example, the occupant protection means may be an energy absorbing member such as a pad. In this case, the energy absorbing member moves toward the passenger compartment side and deforms the roof trim 18 by the vehicle body entering the passenger compartment side. However, the energy absorbing member is interposed between the head of the occupant and the vehicle body to protect the occupant. At this time, there is a possibility that the coat hook 31 and the opening member 41 may be detached from the roof trim 18 due to the deformation of the roof trim 18. By adopting the interior structure described in the first to third embodiments, the coat hook 31 or The opening member 41 can be prevented from coming off the roof trim 18.

  Further, the interior member is not limited to the coat hook 31 and the opening member 41, but may be any member as long as it can be attached to the roof trim 18.

  Further, the periphery of the vehicle body engagement hole 11d of the inner panel 11a may be a protrusion protruding toward the vehicle compartment, and the mounting base 32 (42) may be disposed on the side of the vehicle interior of the protrusion. By doing so, the gap between the roof trim 18 and the inner panel 11a is reduced, so that the mounting base body 32a (42a) of the mounting base 32 (42) can be reduced in size, and as a result, the mounting base 32 (42 ) Is reduced, and the deployability of the curtain airbag 21 can be further improved.

  The present invention is useful when attaching an interior member such as a coat hook to a roof trim that is pressed and deformed toward the passenger compartment by an occupant protection means such as an airbag.
