Definitions

  • the present invention relates to a curtain airbag mounting structure in which a curtain airbag that is wound or folded from below and is long in the vehicle front-rear direction is provided above a side surface of a vehicle interior.
  • curtain airbags are airbags that mainly protect the passenger's head from colliding with a side window.
  • the curtain airbag is inflated and deployed over a wide range along the side surface of the vehicle interior such as a side window.
  • Such a curtain airbag is usually attached in the vicinity of the roof side rail above the side door in a state of being rolled up from below or folded from below.
  • an interior member such as a roof head trim (hereinafter, generically referred to as a roof member) is covered thereover so that it cannot be seen from the passenger compartment.
  • the above curtain airbags and roof members may be removed.
  • the curtain airbag device described in Patent Document 1 the curtain airbag is attached to the roof side rail using a detachable clip so that the curtain airbag can be easily removed during maintenance.
  • the curtain airbag device of Patent Document 1 the curtain airbag is combined with the pillar garnish that is an interior member in a slightly complicated manner. It becomes the composition which comes off from the roof side rail. However, if the curtain airbag is removed until simple maintenance is performed, the work may become complicated. Further, since the curtain airbag is installed in a roll state that is long in the vehicle front-rear direction and does not lose its shape, it is not desirable to rework after installation.
  • the present invention has been made in view of such a problem, and an object of the present invention is to provide a curtain airbag mounting structure that can contribute to facilitating maintenance work in a passenger compartment.
  • a typical structure of the curtain airbag mounting structure is a curtain provided with a curtain airbag which is wound or folded from below and which is long in the vehicle front-rear direction above the side surface in the vehicle interior.
  • at least one bracket member installed above the side surface portion, at least one hold member installed on the curtain airbag and attaching the curtain airbag to the bracket member, the bracket member, the curtain airbag, and the hold

  • the bracket is pressed by pushing it toward the bracket member. And having a structure that fits the member.
  • the hold member installed on the curtain airbag is attached to the bracket member by both the claw portion of the curtain airbag and the clip member. Therefore, the hold member cannot be removed from the bracket member simply by removing the clip member. That is, according to the said structure, after attaching each member to a side part once, only a roof member can be removed from a side part by removing a clip member. Therefore, when performing maintenance in the vehicle interior, the roof member can be easily removed without adding a hand to the curtain airbag, so that the operation becomes easier and the shape of the curtain airbag is destroyed. The risk is also reduced.

Since the curtain airbag in which the hold member is installed is long in the vehicle front-rear direction, the curtain airbag is likely to be distorted and difficult to attach to the side surface. Therefore, in the above configuration, the curtain airbag is attached to the side surface together with the roof member by first integrating the curtain airbag with the roof member. Thereby, even if it is a long curtain airbag, a possibility that a shape may be disordered at the time of attachment becomes low.
  • the curtain airbag attachment structure may be a structure in which the roof member is attached to the bracket member by the clip member after the hold member is attached to the bracket member first.
  • the curtain airbag mounting structure can be configured such that the curtain airbag is first mounted on the side surface and then the roof member can be covered thereon, and the curtain airbag is integrated with the roof member as described above. It has a structure that can be attached to the side part after it is made. That is, the attachment procedure can be selected in accordance with the work situation, which can contribute to the improvement of work efficiency.
  • the clip member includes an elastic locking portion that penetrates and fixes each member, and has a structure that allows the elastic locking portion to be elastically deformed so that the clip member and the roof member can be detached from the bracket member. Good. If it is a clip member of this composition, it will become possible to remove a roof member from a side part more easily.
  • the above bracket member may have a cutout portion into which the claw portion is fitted, and the cutout portion may have a support portion that supports the claw portion on the lower side. By forming this support portion, it is possible to prevent the hold member from falling downward when the clip member is removed.
