The main chamber portion 110 includes a plurality of chambers defining an interior defined by an upper boundary 111, a lower boundary 112, a front boundary 113, and a front boundary 113, Borders 115, 116, 117, and 118 are formed. The width of the main chamber portion 110 in the width direction of the automobile and the expansion delay time are limited by the chamber boundaries 115, 116,

The lamp chamber portion 130 is formed so as to protrude to the upper portion of the main chamber portion 110 at a substantially middle portion of the upper boundary 111 of the main chamber portion 110, And is defined by the lamp chamber boundary. The lamp chamber boundary forms a communication path 132 communicating with the main chamber part 110 on the rear side thereof, and is limited to a substantially rectangular shape.

More specifically, the lamp chamber portion 130 includes a lamp lower boundary 131 extending from the upper boundary 111 defining the main chamber portion 110 to a predetermined length forward of the main chamber portion 110, A ramp front boundary 133 extending upwardly from the boundary 131; A ramp upper boundary 135 extending beyond the ramp lower boundary 131 rearward from the ramp front boundary 133 and a ramp rear boundary 137 extending downward from the ramp upper boundary 135. The communication path 132 is formed in a section where a difference in length between the upper lamp boundary 135 and the lower lower lamp boundary 131 is generated.

A gas introducing portion 150 is provided at a position adjacent to the communication path 132 from the rear of the lamp rear boundary 137. The gas introducing portion 150 is configured to be connected to the inflator 4 and is inclined at an angle with respect to the upper boundary 111 of the main chamber 110. [ With this configuration, the gas generated from the inflator 4 is distributed to the main chamber portion 110 and the lamp chamber portion 130. The communication path 132 is formed on the rear side of the lamp chamber part 130 and is disposed adjacent to the outlet 151 of the gas introducing part 150 so that the gas from the gas introducing part 150 flows into the communication path 132 So that the lamp chamber 131 can be quickly opened. Accordingly, the lamp chamber part 131 rapidly expands and quickly blocks the upper part of the center pillar 7 and / or the center pillar 7 between the center pillar 7 and the vehicle body 3, Can be prevented from being caught on the upper end of the frame.

A plurality of main brackets 160 fixed to the vehicle body 3 are connected to an upper end of the main chamber part 110 and a sub bracket 170 fixed to the vehicle body 3 at a lower part of the lamp chamber part 130 Respectively.

The sub bracket 170 is connected to one surface of the lamp chamber portion 130 facing the vehicle body 3 side via the connecting member 173. [ One end 173a of the connecting member 173 is looped by the sub bracket 170 and then fixed through the sewing line S1 while the other end 173b of the connecting member 173 is connected to the sewing line S2 To the unexpanded region between the lamp chamber portion 130 and the sub-main chamber portion 110. [ That is, the sub-bracket 170 is disposed between the upper boundary 111 of the main chamber portion 110 and the non-inflated region between the lamp lower portion 131 of the lamp chamber portion 130 and the main chamber 110 shown in Fig. A hatching display part between the lamp part 110 and the lamp chamber part 130).

The connecting member 173 may be connected to the non-inflated area between the main chamber part 110 and the lamp chamber part 130 after removing the sewing line S1 and wrapping the sub bracket 170 by the sewing line S2 have. The sub bracket 170 is fixed to the vehicle body 3 by the fastening bolts 171 and the main bracket 160 is fixed to the vehicle body 3 by the fastening bolts 161. [

The main chamber portion 110 is folded in a zigzag shape from its lower end toward its upper end or wound in a rolling state to maintain a folded state between the vehicle body 3 and the head lining 5. [ In FIG. 3, a state in which the main chamber portion 110 is rolled is shown. Hereinafter, the folding state is defined as a state including folding and rolling as described above.

The lamp chamber part 130 may cover the main chamber part 110 folded in the direction opposite to the folding direction of the main chamber part 110 of the main chamber part 110. The lamp chamber part 130 may be configured to cover the folded main chamber part 110 by a maximum of one turn. 3, a part of the folded main chamber part 110 is shown surrounded by the lamp chamber part 130. As shown in FIG.

The lapping member 180 is configured to enclose the main chamber portion 110 and the lamp chamber portion 130 folded at a position corresponding to the lamp chamber portion 130. The lapping member 180 forms a tear line 181 in the middle thereof to fold the main chamber portion 110 and the lamp chamber portion 130 when the lamp chamber portion 130 and the main chamber portion 110 are not inflated And the tear line 181 on expansion of the main chamber portion 110 and the lamp chamber portion 130 may be configured to be ruptured.

One end of the lapping member 180 is connected between the lamp lower boundary 131 of the lamp chamber part 130 and the upper boundary 111 of the main chamber part 110 and the other end of the ramping member 180 is fastened A hole 182 is formed. The fastening holes 182 surround the folded main chamber part 110 and then engage the sub bracket 170 to hold the main chamber part 110 in a folded state. The ramping member 180 is disposed in front of the communication path 132 of the lamp chamber part 130 and restrains a part of the main chamber part 110 located in front of the communication path 132 of the lamp chamber part 130 .

The lapping member 180 thus maintains the main chamber portion 110 in a temporarily folded state at a position corresponding to the lamp chamber portion 130. [ That is, when the gas is initially supplied from the gas introducing portion 150, the lapping member 180 temporarily reserves the main chamber portion 110, so that the gas from the gas introducing portion 150 is preferentially introduced into the lamp chamber portion 130, . As a result, the lamp chamber portion 130 expands faster than the main chamber portion 110, and quickly cuts off the space between the vehicle body 3 and the center pillar 7. On the other hand, the main chamber portion 110 is guided by the lamp chamber portion 130 to be inflated toward the inside of the automobile while bouncing toward the inside and the top of the automobile.

As a result, the main chamber portion 110 can be downwardly deployed without being caught by the center pillar 7 and smoothly facing the inside of the automobile.

Next, the operation of the airbag apparatus of the present invention constructed as described above will be described.

Fig. 4 is a front view showing the curtain airbag of the present invention in an initial inflated state, and Fig. 5 is a longitudinal sectional view taken along line V-V in Fig.

1, 2, 4 and 5, the gas generated from the inflator 4 in the event of an automobile collision is introduced through the gas introducing portion 150, and the gas introduced into the gas introducing portion 150 is introduced into the main chamber portion (110) and the lamp chamber part (130). At this time, the lapping member 180 surrounds a part of the front of the communication path 132 of the lamp chamber part 130 so that the gas of the gas introduction part 150 is preferentially introduced into the lamp chamber part 130 through the communication path 132 .

As a result, the lamp chamber portion 130 is expanded in the space between the vehicle body 3 and the center pillar 7 preferentially in comparison with the main chamber portion 110. Subsequently, as the gas is supplied from the gas introducing portion 150, the main chamber portion 110 is continuously expanded while the lapping member 180 is ruptured. At this time, the space between the center pillar 7 and the vehicle body 3 and the upper end of the center pillar 7 are blocked by the linearly-extending lamp chamber part 130, It can be smoothly expanded toward the inside of the automobile while being prevented from intruding into the inside of the pillar 7.

Fig. 6 is a front view showing a state in which the curtain airbag of Fig. 4 is further inflated, and Fig. 7 is a longitudinal sectional view taken along line VII-VII of Fig.

2, 6 and 7, the lamp chamber portion 130 is further inflated and expanded while occupying a space between the center pillar 7 and the vehicle body 3.

According to the present invention, gas is preferentially supplied into the interior of the lamp chamber portion 130 during the initial inflation of the airbag through the wrapping member 180 to expand the lamp chamber portion 130 faster than the main chamber portion 110. The lamp chamber portion 130 expands quickly in the space between the vehicle body 3 and the center pillar 7 to block the space between the vehicle body 3 and the center pillar 7. [ Therefore, it is possible to prevent the main chamber portion 110 from penetrating into the center pillar 7, and to prevent the main chamber portion 110 from interfering with the center pillar 7.

The gas is rapidly supplied to the lamp chamber portion 130 by the lapping member 180 and the lamp chamber portion 130 is instantaneously inflated so that the main chamber portion 110 is bounced toward the inside and the top of the automobile The effect of preventing the main chamber portion 110 from interfering with the center pillar 7 can be enhanced.

The lapping member 180 may cover the upper end of the center pillar 7 when the lapping member 180 is deployed to prevent the main chamber 110 from entering the center pillar 110. [

Fig. 8 is a front view showing a configuration of a curtain airbag according to another embodiment of the present invention, showing a modification of the lapping member having the above-described configuration. Fig.

Hereinafter, the same reference numerals are assigned to the same components as the above-described components, and redundant description is omitted.

Referring to FIG. 8, the lapping member 280 may be constructed to have a length corresponding to the lamp chamber 130 and cover the area substantially corresponding to the lamp chamber 130.

The front portion of the wrapping member 280 is connected to the non-expansion region between the upper boundary 111 of the main chamber portion 110 and the lamp lower boundary 131 of the lamp chamber portion 130, And the rear end side of the wrapping member 280 is connected through the sewing line S3 between the lamp rear portion boundary 131 of the lamp chamber portion 130 and the gas introducing portion 150. [

With this configuration, the lapping member 280 can be lifted up to a position corresponding to a partial area A1 of the main chamber part 110 and the communication path 132 corresponding to the front of the communication path 132 of the lamp chamber part 130 Thereby restricting the partial area A2.

As a result, the gas from the gas introducing portion 150 further increases the amount of gas supplied to the communication passage 132 during the initial supply, so that the lamp chamber portion 130 expands at a higher rate than the main chamber portion 110 Lt; / RTI >
