TECHNICAL FIELD OF THE INVENTION
The present invention relates to a roof side inner garnish, and more particularly to a roof side inner garnish for forming a deployment space when an airbag bag is deployed and inflated.
[0002]
[Prior art]
As a roof side inner garnish to form a deployment space when the air bag body is deployed and inflated, a garnish that covers the air bag body that is folded and stored from the rear pillar inside the car to the roof side rail is the rear pillar part. The garnish is attached to the main body using a clip, and the garnish is disposed on the upper end side of the main body where the mounting seat for the clip is arranged and the airbag bag body at the time of deployment and inflation. There has been known a configuration in which an unfolded portion that is pressed and opened is integrally formed (see, for example, Patent Document 1).

[Problems to be solved by the invention]
However, in such a roof side inner garnish, when a window opening is formed in the roof side inner garnish, a window opening is formed below the deployed portion which is pressed by the airbag bag body when deployed and inflated. Is done. For this reason, it is difficult to reliably hold the deployed portion of the roof side inner garnish at a position along the roof side rail, and a gap is generated between the roof glass and the window glass, and the appearance quality is reduced.
[0005]
In consideration of the above facts, the present invention provides a roof side inner that can reliably hold a deployment portion above a window opening at a position along a roof side rail and can greatly expand the deployment portion when an airbag body is deployed. The goal is to get a garnish.
[0006]
[Means for Solving the Problems]
The present invention according to claim 1 is a roof side inner garnish in which a window opening is formed, and a periphery of the window opening is integrated.
An unfolding part that forms a part on the upper side of the window opening;
A connecting portion formed on the deploying portion and deforming when the airbag body is inflated and inflated to support the deploying portion so as to be relatively movable with respect to the roof side rail;
A stopper formed on the connecting portion and holding the deployment portion on the roof side rail, and preventing the deployment portion from coming off the roof side rail when the airbag body is deployed and inflated;
It is characterized by having.
[0007]
Therefore, when the airbag bag is deployed and inflated, the deploying portion forming the upper portion of the window opening formed in the roof side inner garnish is deformed by the deformation of the connecting portion formed in the deploying portion. Since the air bag body is relatively moved with respect to the side rails, the deployment portion can be largely deployed when the air bag body is deployed. Further, the deployment portion can be prevented from completely coming off the roof side rail by the stopper formed in the connection portion. On the other hand, during normal use, the deployed portion is held on the roof side rail by the stopper of the connecting portion formed on the deployed portion. For this reason, the deployed portion above the window opening in the roof side inner garnish can be reliably held at a position along the roof side rail.

As shown in FIG. 1, the connecting portion 24 of the roof side inner garnish 10 includes a main body 26 extending obliquely outward from the upper surface 22 </ b> A of the deploying portion 22 to the upper side of the vehicle body. An engagement portion 28 is formed on 26A toward the outside in the vehicle width direction. An inclined portion 30 extending obliquely upward from the vehicle body is formed at a tip end of the engaging portion 28, and a stopper 32 is provided on a lower surface of an end of the engaging portion 28 on the inclined portion 30 side. Is formed. The shape of the stopper 32 as viewed from the vehicle front-rear direction is a triangle.
[0014]
The engaging portion 28 and the inclined portion 30 of the connecting portion 24 of the roof side inner garnish 10 are attached to the mounting hole 42 formed in the side wall portion 40A of the roof side rail inner panel 40 constituting the vehicle body inner portion of the roof side rail 38. It is inserted from the indoor side. Further, the stopper 32 of the connecting portion 24 is engaged with the outer side surface of the lower end edge portion 42A of the mounting hole 42, and holds the deployed portion 22 of the roof side inner garnish 10 to the roof side rail inner panel 40. .
[0015]
The vehicle width direction inner edge 22B of the deployment portion 22 in the roof side inner garnish 10 is in contact with the vehicle interior side surface of the vehicle width direction outer edge 46A of the ceiling member 46. A well-known curtain shield airbag bag 50 is disposed on the vehicle side of the inner panel 40 along the longitudinal direction of the vehicle body in a folded state.
[0016]
Therefore, as shown in FIG. 2, when the curtain shield airbag bag 50 is deployed and inflated at the time of a vehicle collision, the deployment portion 22 of the roof side inner garnish 10 is moved toward the vehicle interior by the deployment and inflation force of the curtain shield airbag bag 50. Since the connecting portion 24 is deformed, the connecting portion 24 is deformed, and the deploying portion 22 moves relative to the roof side rail inner panel 40 downward (in the direction of arrow A in FIG. 2). At this time, the stopper 32 is engaged with the lower end edge portion 42A of the mounting hole 42, so that the developing portion 22 is prevented from completely coming off the roof side rail inner panel 40.
