- 108 a is attached to a mounting point 31 b provided at a position rearward of the center rail 33 of the roof rail 31.
- the substantially middle position of the rear band-shaped portion 108 is raised to the height of the reference rail 31, resulting in a naturally mounted state.
- the slack S is generated across the cylindrical expansion portion 102 on the rear side, and the rearmost one of the mounting portions 105 a of the upper edge 105 and the band-shaped portion are formed.
- a notch U is formed between the attachment portion 108 and the attachment portion 108a.
- the mounting portions 105a of the upper edge 105 of the curtain-shaped airbag 10 are elongated holes extending in the lateral direction, and the pitches of the mounting portions 105a are different from each other. Is longer than the pitch of the mounting points 31a provided on each of the rails 31 and each of the mounting points 31a is in the form of a pin having a head. Attaching the long hole-shaped mounting part 105a provided at the upper edge 105 of the curtain-shaped airbag 10 to the body of the mounting point 31a loosely and holding it with the head Curtain airbag 1
- the upper edge 1 0 5 is slightly loosened between the mounting portions 1 0 5 a and is mounted on the roof rail 3 1. Due to the looseness between the crossing slack S, the notch U, and the mounting area 105 a of the upper edge 105, the air bag 10 in the naturally mounted state is not tensed. As shown in Fig. 4, winding storage is possible.
- the winding direction of the curtain-shaped airbag 10 in the stored state is the direction in which the lower edge 106 is bent inside the vehicle and wound. Have been.
- the rear cylindrical inflatable portion 102 is formed so as to be substantially along the center villa 133 in the deployed state.
- the inflate 2 when the inflate 2 is operated, first, gas is injected into the laterally expanding portion 104, and the tubular member on the rear side is passed through the laterally expanding portion 104. Gas is sequentially injected into the inflatable portion 102, the protective inflatable portion 103 and the front tubular inflatable portion 101. At the initial stage of operation of the inflator 2, the tubular inflatable portion 102 expands as the lateral inflatable portion 104 expands. At this time, the tubular inflatable portion 102 expands. Since 102 is connected from the vicinity of the upper edge 105 of the curtain-shaped airbag 10 to the vicinity of the lower edge 106, it is formed on the lower edge 106 by expansion and expands.
- each of the mounting portions 105a of the upper edge 105 has a force of 105 a. Since each of the mounting points 3 1a is loosely attached to each of the mounting points 3 1a, the mounting portions 1 05a are moved appropriately as well as the notch U expands. The expansion operation of 02 becomes smooth.
- the curtain-shaped airbag 10 is wound and housed in the direction shown in FIG. 8, and is substantially along the center pillar 33 when the tubular inflatable portion 102 is in the expanded state. Because it is formed at the position, the curtain-shaped airbag 10 is deployed so as to be smoothly rewound along the inside of the vehicle cabin, and at the time of deployment, the cylindrical inflatable portion 102 is attached to the center villa 13. Guided by 3 and the side window Even when it is open, the curtain-shaped airbag 10 is securely fixed at a certain position and does not go out of the vehicle.
- the lateral expansion portion 104 continuously formed along the lower edge 106 of the curtain-shaped airbag 10 is used for the operation of the infrastructure 2.
- the tube expands (extends) in the cylindrical expansion section 102 to be pulled downward and move. Therefore, the lower edge 106 of the curtain-shaped airbag 10 has a three-dimensional structure to which rigidity is imparted by expansion, and a downward force is applied to an intermediate portion thereof, whereby the tension is applied.
- the lateral expansion portion 104 is sandwiched between the seat and the door or the side wall of the vehicle body.
- the positioning function when the curtain-shaped airbag 10 is deployed becomes extremely stable.
- the rigidity of the lateral expansion portion 104 becomes extremely high, and the occupant crashes. It has been confirmed that there is no bending.
- the rear pillar end of the lower edge of the curtain-shaped bag is attached to a mounting point along the railroad rail, and the one end of the front Villa
- the end of the rear rail was installed at a lower mounting point than the roof rail. May be mounted lower than the roof rail, and the end on one side of the front villa may be mounted along the roof rail. Both ends may each be mounted at a mounting point lower than the roof rail.
- the curtain-shaped airbag is formed with one or several cylindrical inflatable portions that are connected from the vicinity of the upper edge to the vicinity of the lower edge thereof, whereby During operation of the frame, the cylindrical inflatable portion expands, giving an effective tension to the lower edge of the curtain-shaped bag, and the deployed position can be fixed at a fixed position.
- the curtain-shaped airbag is stabilized in the required deployment position without causing loosening of the lower edge under less sewing or welding. To secure the occupants.
- the amount of gas required for deployment is smaller than that of the conventional device, so that the occupant can be protected by using a small-capacity inflator.
- a low-cost, high-performance airbag system can be obtained, and the final deployment is achieved because the amount of gas required for deployment is small. It is possible to shorten the time required for the occupants, and to quickly take the posture for protecting the occupants.
- the protective inflation part for protecting the occupants can be arbitrary, and by adopting the optimal shape that matches each vehicle type, the occupant protection function is also improved. Can be raised.
- the curtain-shaped airbag can be smoothly expanded without affecting the opening and closing of the side window, and the occupant can be opened. Can be protected.
- the bending and twisting directions are provided on the lower edge during operation of the inflator. It is possible to apply a tension and to fix the positioning while providing rigidity to the stiffness.In addition, this lateral expansion part is fixed by being sandwiched between the sheet and the door etc. Thus, more reliable and stable positioning and occupant protection can be achieved.
