Description

  The present invention belongs to a technical field related to an assembling structure and an assembling method of a curtain airbag device having a curtain member that is deployed so as to cover a side window portion including a side window and a pillar of a vehicle.

  Conventionally, as shown in, for example, Patent Document 1, a curtain-like airbag (curtain member) is folded and accommodated at an upper edge portion of a side window portion including a side window and a pillar of a vehicle, and a vehicle collision occurs. 2. Description of the Related Art A curtain airbag device is known in which gas is supplied to the curtain member at the time or rollover to inflate and deploy the curtain member so as to instantaneously cover a side window portion. In this device, the curtain member in the accommodated state extends in the vehicle front-rear direction along the roof side rail of the vehicle with the passenger compartment side covered with a roof trim, and when the curtain member is deployed, the curtain member is unfolded. The roof trim is deformed by pressure, and a curtain member extends from the roof trim to a side lining or weather strip provided on the upper edge of the side window to cover the side window. Further, a part of the curtain member (portion located on the upper side of the pillar) is developed into the vehicle interior from the boundary between the roof trim and the pillar trim constituting the surface of the pillar on the vehicle interior side.

  Since the pillar trim is made of a member that is harder than the roof trim, the curtain member may be caught by the pillar trim when the curtain member is deployed from the boundary to the vehicle interior. Therefore, in order to further improve the deployability of the curtain member. In addition, in Patent Document 1, a guide member (jump base) that guides the curtain member to expand toward the passenger compartment when the curtain member is deployed may be provided on the inner panel or pillar trim of the roof side rail. Proposed.

In Patent Document 2, a guide member extending upward from the vicinity of the upper end of the pillar trim is formed integrally with the pillar trim, and a guide portion is formed at the upper end of the guide member to guide the curtain member so as to be deployed toward the passenger compartment. In addition, it has been proposed that the upper end portion of the pillar trim and the guide member form an engaging groove that engages with the side edge portion of the roof trim. Furthermore, in this patent document 2, it is proposed that a rib projecting into the engagement groove is formed on the guide member, and the side edge of the roof trim is pressed with this rib to prevent the roof trim from coming off. ing.

  By the way, the roof trim is made of a soft member such as a foaming urethane resin because it needs to be deformed by the unfolding pressure when the curtain member is unfolded. For this reason, when the roof trim is pressed from the passenger compartment side to the vehicle outer side, the roof trim is easily deformed to the vehicle outer side. Therefore, the portion of the side edge of the roof trim that is engaged with the side lining or the weather strip is prevented from being deformed even if the side edge of the roof trim is pressed to the outside of the vehicle by the engagement.

  However, in the vicinity of the boundary of the roof trim with the pillar trim, only the upper end of the pillar trim covers the passenger compartment side, and the deformation of the roof trim in the vicinity of the boundary with the pillar trim is restricted to the outside of the vehicle. Generally, there are no members. Therefore, if the occupant unexpectedly presses the vicinity of the boundary of the roof trim with the pillar trim, the roof trim is deformed to the outside of the vehicle, and this deformation deteriorates the appearance and affects the deployability of the curtain member. There is a possibility of effect.

  Therefore, for example, when a guide member is integrally formed at the upper end portion of the pillar trim as in Patent Document 2, a restriction portion for restricting deformation of the roof trim to the vehicle outer side is integrally formed on the guide member, and the restriction portion is formed. Thus, it can be considered that the side edge of the roof trim (near the boundary with the pillar trim) is pressed from the outside of the vehicle.

  However, when the restriction part as described above is formed integrally with the guide member, the roof trim has a portion near the boundary with the pillar trim that extends obliquely downward toward the bottom of the pillar. The restricting part that holds the trim from the outside of the vehicle becomes large. For this reason, when attaching the pillar trim to the vehicle body, it is difficult to insert the restricting part between the roof trim and the vehicle body unless special measures are taken. Become. As a result, the assembling property of the pillar trim to the vehicle body is deteriorated.

  The present invention has been made in view of such a point, and an object of the present invention is to make the vicinity of the boundary between the roof trim and the pillar trim with a simple configuration without deteriorating the assembling property of the pillar trim to the vehicle body. The object is to prevent the outer side of the vehicle from being deformed even when pressed toward the outer side of the vehicle.

  In order to achieve the above object, according to the present invention, a position adjusting member is provided in the vicinity of the upper end of the pillar trim, and the position adjusting member allows the curtain member in the accommodated state to be located outside the vehicle near the boundary with the pillar trim in the roof trim. The position of the curtain member can be adjusted so as to be close to the surface.

  Specifically, in the first aspect of the invention, the vehicle is accommodated at the upper edge of the side window portion including the side window and the pillar of the vehicle in a state in which the passenger compartment side is covered with a roof trim, and is expanded by gas injection. A curtain member that deforms the roof trim so as to cover the side window portion, and a part of the curtain member is formed of the roof trim and a member harder than the roof trim, and the pillar The present invention is directed to an assembly structure of a curtain airbag device configured to be deployed in a vehicle interior from a boundary with a pillar trim that forms a surface on the vehicle interior side.

  A position adjusting member is provided in the vicinity of the upper end of the pillar trim so that the curtain member in the housed state is close to a vehicle outer surface near the boundary in the roof trim. It shall be.

That is, even when the curtain member is attached to the vehicle body, a portion of the curtain member located above the pillar is not attached to the vehicle body, and is movable up and down by a certain amount. . Since the upper end of the pillar trim is usually at a lower position than the curtain member so that the curtain member is not caught, the assembling operator pulls the position adjusting member, for example, to place the portion of the curtain member positioned above the pillar. By moving it downward, for example, the portion can be brought close to the surface outside the vehicle near the boundary with the pillar trim in the roof trim. Thus, if the curtain member is brought close to the vehicle outer surface in the vicinity of the boundary in the roof trim, the curtain that is relatively hard in the folded state even if the vicinity of the boundary in the roof trim is pressed to the vehicle outer side. By the member, the deformation in the vicinity of the boundary in the roof trim can be suppressed. As a result, the appearance can be prevented from deteriorating, and the development stability of the curtain member can be ensured.

  According to a second aspect of the present invention, in the first aspect of the present invention, in the vicinity of the upper end of the pillar trim, the vehicle interior is directed downwardly so as to guide the curtain member to expand toward the vehicle interior when the curtain member is expanded. A guide portion that is inclined to the side is provided, and the position adjusting member moves the curtain member in the accommodated state downward along the guide portion at the time of the position adjustment. Suppose that it is comprised so that it may adjoin to the surface of the vehicle outer side of the boundary vicinity.

  As a result, the curtain member moves downward along the guide portion, so that the curtain member also moves to the vehicle compartment side. Therefore, the curtain member can be easily brought close to the vehicle outer surface near the boundary with the pillar trim in the roof trim. Further, even if the position is adjusted, the guide property of the curtain member by the guide portion is almost the same as that before the adjustment, and good developability can be maintained. Therefore, the position of the curtain member can be easily and reliably adjusted by effectively using the guide portion that improves the deployability into the vehicle interior.

  According to a third aspect of the present invention, in the second aspect of the present invention, the position adjusting member includes a vertically extending portion that extends in a vertical direction on the vehicle outer side of the curtain member in the accommodated state, and an upper end of the vertically extending portion.

In addition, since the lower extension 45e is set in advance to have a length that extends below the roof trim 34, the position of the lower extension 45e can be reduced by simply allowing the lower extension 45e to hang naturally. The lower part of the adjustment member 45 is extended below the roof trim 34 (see FIG. 6). In this state, the lower end of the lower extending portion 45 e is positioned above the pin 63.

  Next, the position of the movable portion 20a of the curtain member 20 is adjusted by pulling the lower portion (lower extending portion 45e) of the position adjusting member 45 downward. That is, the second pillar trim in the roof trim 34 is moved while the movable portion 20a is moved downward along the guide portion 40 by pressing the movable portion 20a downward by the front and rear pressing portions 45c and 45d. The vehicle is brought close to the outer surface of the vehicle near the boundary with 57. Thereby, the movable part 20a changes from the state indicated by the two-dot chain line in FIG. 3 to the state indicated by the broken line. Further, as shown in FIG. 4, the movable portion 20 a contacts the vertical center portion or the lower portion of the guide portion 40, and contacts the vehicle outer surface in the vicinity of the boundary with the second pillar trim 57 in the roof trim 34. To do. The movable portion 20a is not necessarily in contact with the vehicle outer surface in the vicinity of the boundary in the roof trim 34. When the vicinity of the boundary in the roof trim 34 is pressed to the vehicle outer side, the vehicle outer side of the roof trim 34 is not necessary. It is only necessary to be close enough to suppress deformation (deformation that affects the appearance and development stability of the curtain member 20).

  When the position is adjusted, the assembling worker inserts the pin 63 into the vehicle body mounting hole 45f located on the lowermost side or one of the plurality of vehicle body mounting holes 45f formed in the lower extending portion 45e. The lower extending portion 45e is attached to the pillar inner 61b by fitting.
