DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment according to the present invention will be described with reference to FIGS.

(1) Configuration of Airbag <A> Outline As shown in FIG. 4, the airbag has an inflator (not shown) disposed in an instrument panel 12 located in front of a cabin 11 of a vehicle body 10. When a sensor (not shown) (not shown) detects an acceleration or a load equal to or more than a predetermined value, the inflator is activated. A cover member 20 called a garnish is arranged along the roof side 14 from a front pillar (A pillar) 13 and is attached to the vehicle body 10 so as to be expandable by a clip device 30 described later. The bag is housed inside the cover member 20. Then, as shown in FIG. 5, the gas ejected from the inflator at the time of the side collision is filled in the bag 40, and the cover member 20 and the vehicle body 10 which are pushed open by using the inflation force of the bag 40 are opened.
By inflating and deploying the bag body 40 from the bulging opening into the passenger compartment 11, the occupant's head can be mainly protected.

<B> Sectional Structure of Airbag FIG. 1 shows a section of the roof side 14 at the installation position of the clip device 30 shown in FIG.
5, an inner panel 16 is disposed on the vehicle interior side. The inner panel 16 is bent toward the cabin 11 to form a raised portion 16.
a is formed, and the raised portion 16a and the skeletal member 15 are formed.
A space 17 is formed between them.

As shown in FIG. 2, a mounting hole 18 and a large introduction hole 1 are provided on the plate surface of the raised portion 16a of the inner panel 16.
8a communicate with each other to form a gourd. Hereinafter, the main members will be described in detail.

[Cover Member] As shown in FIG. 1, the cover member 20 has a substantially C-shaped cross section, and its surface 20a
Is formed as a good-looking continuous surface over its entirety. In the lower half of the back surface 20b of the cover member 20, a bag 4
0 is formed in the storage space 22. At the center of the back surface 20b of the cover member 20, a plurality of mounting pedestals 21 are formed so as to protrude in accordance with the intervals at which the mounting holes 18 are formed. An inlet 24 is formed in the seating surface 23 at the top of the mounting base 21 along the longitudinal direction of the cover member 20, and the seating surface 2 is provided.
3 and the inside of the seating surface 23 at a predetermined distance from the bottom surface 2
5 is formed, and an introduction space 26 is formed between the seating surface 23 and the bottom surface 25. The introduction port 24 is set to a size that allows the shaft portion 51 of the connecting pin 50 to be described later to be inserted and restricts the pin head 52 from coming out, and the introduction space 26 is inserted from the side of the mounting base 21. The pin head 52 is formed in such a size and shape that the pin head 52 can be accommodated without rattling.

The cover member 20 and the mounting base 21 described above.
In consideration of moldability, manufacturing cost, aesthetics, and the like, it is desirable to form the resin by, for example, integrally molding various resins. In addition, reference numeral 19 in FIG. 1 denotes an opening weather strip that covers the projecting end of the skeleton member 15 along the longitudinal direction. In the present embodiment, since the clip device 30 is attached to the mounting base 21 formed on the back surface 20b of the cover member 20, there is no member that penetrates the cover member 20, and therefore, the appearance of the front surface 20a of the cover member 20 is reduced. Can be kept good.

<C> Clip Device In the present embodiment, a case where the clip device 30 is constituted by a connecting pin 50 made of resin will be described. Figures 1 and 2
As shown in the figure, the connecting pin 50 has a cylindrical shaft portion 50, a pin head 52 bulged to one of the shaft portions 51, an annular portion 53 formed facing the pin head 52, A hemispherical stopper 54 formed on the other side of the pin head 51 of the portion 51, an umbrella-shaped flange 55 formed on the annular portion 53 of the shaft 51, and the stopper 54 and the flange 55. It is constituted by a plurality of elastic legs 56 formed by opening the legs on the shaft portion 51 between them, and these are formed by integral molding with various resins.

The pin head 52 and the annular portion 53 of the connecting pin 50
Are formed at intervals capable of holding the seating surface 23 of the cover member 20.

The stopper portion 54 can be inserted into an introduction hole 18a formed in communication with the mounting hole 18, and can be inserted into the mounting hole 1a.
The outer peripheral surface is formed as a spherical surface 54a. Stopper part 54
The reason why the connecting pin 50 is tilted (pivoted) with respect to the mounting hole 18 is to lock the connecting pin 50. The stopper portion 54 comes into contact with the back surface of the mounting hole 18 after the engagement of the elastic leg 56 with the mounting hole 18 is released,
Since this is a portion for preventing the connection pin 50 from coming off, the push-opening amount (expansion amount) of the cover member 20 at the time of a side collision is changed from the engagement portion 56a of the elastic leg 56 constituting the connection pin 50 to the stopper portion 54. It is determined by the set distance to.

The diameter of the flange 55 is tapered from the position below the neck of the annular portion 53 toward the elastic leg 56, and the maximum diameter thereof is set to be larger than that of the mounting hole 18.

The elastic leg 56 is moved toward the flange 55 so that the shaft 5
1 is formed so as to radially protrude outward, and an engaging portion 56a that can be engaged with the mounting hole 18 is formed on the outer peripheral surface of the free end. The engaging portion 56a is desirably formed as a step surface. An elastic force (spring force) is applied to the elastic leg 56 such that the engaging portion 63b is brought into elastic contact with the inner peripheral edge of the mounting hole 18 to restrict the connection pin 50 from coming off. The total length of the elastic leg 56 is such that when the flange 55 contacts the raised portion 16a of the inner panel 16, the engaging portion 63b
Is set to a length that can engage with the inner peripheral edge of the mounting hole 18.

(2) Attaching method of cover member <A> Attaching of connection pin As shown in FIG. 1, the pin head 52 of the connection pin 50 does not come out of the mounting base 21 of the cover member 20 in the axial direction. It is attached. As a method of attaching the connecting pin 50 to the mounting base 21, for example, one side of the mounting base 21 is opened to open the introduction port 24 and the introduction space 26, and the pin head 52 is introduced from the side of the mounting base 21. Or mounting base 2
The first inlet port 24 is formed as a continuous port having a horizontally long large port through which the pin head 52 can be inserted and a small port through which only the shaft portion 51 can be inserted. After the pin head 52 is inserted and guided into the introduction space 26, the connecting pin 50 can be moved in parallel to the small-sized mouth side and connected.

<B> Attaching the cover member The stopper portion 54 of the connecting pin 50 faces the introduction hole 18a of the inner panel 16, and only the stopper portion 54 is inserted into the introduction hole 18a. Move sideways. Next, the connecting pin 5 and the cover member 20 are connected together.
Press 0 to attach.

The connection operation when the connection pin 50 is pushed into the mounting hole 18 of the inner panel 16 will be described. The connecting pin 50 is inserted into the mounting hole 1 with the stopper 54 inserted therein.
8, each elastic leg 56 of the connecting pin 50 comes into contact with the inner peripheral surface of the mounting hole 18, and further pressing causes each elastic leg 56 to be elastically deformed in the radially-reducing direction to accumulate a resilient force. .
When the engaging portion 56a of each elastic leg 56 reaches the mounting hole 18,
The flange 55 of the connecting pin 50 abuts on the surface of the inner panel 16 and further pushing is restricted. For this reason, each engaging portion 56a is attached to the mounting hole 1 by the elastic force in the radially expanding direction stored in each elastic leg 56 of the connecting pin 50.
8 will be engaged with the inner peripheral surface. Therefore, even if an external force acts in the direction in which the mounting hole 18 comes out due to the weight of the cover member 20 or the like, as long as the external force does not exceed the elastic force of each elastic leg 56 engaged with the mounting hole 18, the connecting pin 50
Does not come out of the mounting hole 18.

(3) Operation of Airbag at Side Impact In FIG. 1 showing the airbag in an inactive state, when a side impact is detected, the bag body 40 is filled with a gas such as gas by an inflator (not shown). . As a result, the inflation force of the bag body 40 acts as a pushing force for pushing the cover member 20 in the direction in which the inner panel 16 is separated, and acts as an external force for the connecting pin 50 in the exit direction.

The external force directed in the exit direction is applied to the mounting hole 18.
When the elastic force of the elastic leg 56 of the connecting pin 50 engaged with the elastic pin 56 is exceeded, the engagement between the engaging portion 56a of the elastic leg 56 and the inner peripheral edge of the mounting hole 18 is released. As a result, the cover member 20 moves in the direction away from the inner panel 16, but the spherical surface 54 a of the stopper portion 54 of the connecting pin 50 abuts on the inner peripheral surface of the mounting hole 18, so that the cover member 20 and the connecting pin 50 are Movement is regulated. As shown by a two-dot chain line in FIG.
Is inflated and deployed into the vehicle interior through a bulging opening formed between the inner panel 16 and the cover member 20 by the movement of the cover member 20.

As described above, the elastic legs 56 of the connecting pin 50
Since the engagement with the mounting hole 18 can be released with an external force exceeding the elastic force of the bag body 40, the bag body 40 can be operated smoothly and quickly with a relatively small force at the initial stage of inflation. Since the stopper portion 54 of the connecting pin 50 can be in contact with the entire inner peripheral surface of the mounting hole 18, the contact load between the contact surfaces of the two can be dispersed, and a large slip-out preventing resistance can be expected. In particular, since the connecting pin 50 can be tilted (pivoted) while the spherical surface 54a of the stopper portion 54 is in contact with the mounting hole 18, the connecting pin 50 is rotated counterclockwise in FIG. 3 around the contact portion. A wider swelling opening can be formed between the inner panel 16 and the inner panel 16. Therefore, compared to the case where the cover member 20 is simply moved in the extension direction of the connection pin 50, the bag 40 with respect to the sliding amount of the cover member 20 has more favorable deployability.

Although the case where the cover member 20 is continuously mounted from the front pillar (A pillar) 13 to the roof side 14 has been described above, although not shown, the A pillar 13 and the roof side 14 are separated. Of course, the present invention can also be applied to a case where the cover member is attached, a case where the cover member is separated and attached at the installation position of the assist grip, or a case where the cover member is attached to the C pillar.

Embodiment 10 FIGS. 37 to 39 show two kinds of connecting means having different functions (mounting connecting pin 50A and stopper connecting pin 50B) mounted on the back surface of the cover member 10 and mounted on the inner panel 16. FIG. Another embodiment will be described.

(1) Configuration [Mounting Connecting Pin] As shown in FIG. 38, the mounting connecting pin 50A engages with the inner panel 16 to cover the cover member 20.
A shaft member 51, a pin head 52, an annular portion 53, a stopper portion 54, and a flange 55.
And it is molded integrally with resin. Stopper part 5
4 has a rhombic shape as a whole, and forms an inner hole 54f between the soft leg portion 54d and the hard leg 54e. The maximum diameter portion of both legs 54d and 54e constituting the stopper portion 54 is formed to have a larger diameter than the circular mounting hole 18A, and the soft leg portion 54d is elastically deformed inward when the mounting connecting pin 50A is inserted. The two legs 54 inserted through the mounting holes 18A and restored after passing
The inner panel 16 can be attached to the inner panel 16 by the d and 54e and the flange 55.

[Connector Pin for Stopper] As shown in FIG. 39, the connector pin 50B for stopper is a pin member for restricting a moving amount of the cover member 20 to a certain range at the time of a side collision. And annular portion 53 and stopper portion 54
And resin or metal. The shaft portion 51 of the stopper connecting pin 50B is connected to the mounting connecting pin 50A.
The stopper portion 54 is formed so as to be separated from the back surface of the inner panel 16 when the cover member 20 is mounted. The stopper portion 54 is dimensioned so that it can be inserted into the gourd-shaped introduction hole 18a and cannot escape from the mounting hole 18B.

As a result, the mounting connecting pin 50A mounted on the cover member 20 first faces the mounting hole 18A. When the cover member 20 is pushed in this state, the connecting pins 50B for stoppers are pressed.
The stopper 54 only moves to the inner side of the hole, but when the stopper 54 of the mounting connection pin 50A elastically deforms inward and passes through the mounting hole 18A, the flange 55 comes into contact with the inner panel 16. Thus, the engagement with the mounting hole 18A is completed. The detachment resistance of the cover member 20 is determined by the elastic force of the two legs 54d and 54e of the stopper 54 engaging with the mounting hole 18A.

[Operation at Side Impact] At the time of side impact, the cover member 20
An external force acts in the pull-out direction, and the external force acts on an engaging portion between the stopper portion 54 of the mounting connecting pin 50A and the mounting hole 18A. When the external force at the time of the side collision becomes larger than the engaging force of the engaging portion, the stopper portion 54 of the mounting connecting pin 50A is contracted and disengaged from the mounting hole 18A, and the cover member 20 is disengaged.
Moves to the cabin side. The movement of the cover member is restricted to a certain range by the stopper portion 54 of the stopper connecting pin 50 </ b> B abutting on the back surface of the inner panel 16. Therefore, the maximum opening amount of the cover member 20 is determined by the set length of the shaft portion 51 of the stopper connecting pin 50B.

According to this embodiment, in addition to the same advantages as those of the above-described embodiment, both connecting pins 50
The shape and structure of A and 50B are simple and easy to manufacture. Moreover, since the connecting pins 50A and 50B can be selectively used for each function, it is possible to arbitrarily set the mounting force of the cover member 20 and the resistance to movement of the cover member 20 in the event of a side collision.
