Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to an airbag device provided in these seats in order to prevent or mitigate a secondary collision of an occupant in various vehicles such as automobiles.

[0002]

[Prior Art]

 In vehicles such as passenger cars, airplanes, and trains, where seats have been arranged side by side in the front-rear direction, the airbag stored in the folded state at the rear and lower parts of the seat expands backward from the seat when it expands. There is known a rear seat airbag device that protects an occupant who takes out and sits in the rear seat. (For example, refer to the description in Japanese Patent Application Laid-Open No. 2-212239.) Further, an airbag device for a front seat such as a driver's seat or a passenger seat has also been put into practical use.

[0003]

[Problems to be solved by the device]

 By the way, in vehicles such as passenger cars, it is possible to usually sit in the middle part of the driver's seat in the back seat or the seat behind the passenger seat, and depending on the type, also in the middle part of the driver's seat in the front seat or the passenger seat. You can do it. However, in the above-described conventional airbag device for seats, since the airbags are arranged so as to face each seat, the swelling of the airbag causes the driver's seat, the passenger seat, or the rear seats of those seats (hereinafter referred to as The passengers seated in the seats of the seats are referred to as "seating seats", but the passengers seated in the middle portions of these seats (hereinafter, these seats are referred to as "intermediate seats") can be protected. If the vehicle is hit by an obstacle, such as when it collides with an obstacle, the occupant seated in the middle seat makes a secondary collision with the front windshield, the front seat, or its supporting member. There was a possibility.

Therefore, an object of the present invention is to prevent a passenger seated in an intermediate seat from secondarily colliding with a front windshield, a front seat, or the like when a shock is applied to a vehicle, or to mitigate the shock. It is to provide a new seat airbag device that can be used.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention comprises a plurality of airbags arranged in front of each seat provided in the left-right direction, and these airbags are directed toward an occupant seated in each seat. In the airbag device for a seat configured to bulge from the front, the airbag having a shape that bulges from both sides and overlaps in front of an occupant seated in an intermediate seat provided in the middle of the seat as each of the airbags. It is characterized by using a bag.

[0006]

[Operation and effect of the device]

 When the airbag device for the seat is configured in this way, the shape of the airbag that bulges toward the seated occupant is formed so as to overlap in front of the intermediate seat. It is possible to protect the human body by preventing the body from jumping forward at the overlapping part, mitigating the impact caused by the secondary collision.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view of a seat of a passenger car equipped with a seat airbag device according to the present invention, FIG. 2 is a diagram showing a state after the airbag device of FIG. 1 is activated, and FIG. 3 is a plan view of FIG. 4 is a perspective view of the airbag device of FIG. 2 in a state where the airbags are separated from each other.

The airbags 11 and 12 of the airbag apparatus of this embodiment are built in in a state of being previously folded above the seat backs 21 and 22 of the front seats and covered with an airbag cover 13. When a passenger vehicle receives a shock such as a collision, the impact detection sensor 14 is activated to rapidly inject gas into the airbags 11 and 12, which causes the airbags 11 and 12 to inflate rearward and forward. The occupant's body is protected by supporting the occupant's body that is about to move and absorbing the impact of the secondary collision. The above-mentioned configuration of the airbag device is known. These airbags 11 and 12 are arranged in front of the rear seats 23 and 24, respectively, but have a shape in which they overlap each other in front of the intermediate seat 25 located in the middle of the respective seats 23 and 24. Therefore, the body of an occupant sitting on the intermediate seat 25 can be supported and protected. Here, the shape of the overlapping portion of the airbags 11 and 12 in front of the intermediate seat 25 will be described more specifically. As shown in FIG. 4, the airbags 11 and 12 on the left and right sides are formed on the respective tip sides. The protrusions 11a and 12a in the direction of the intermediate seat 25 come into contact with the stepped portions 12b and 11b provided on the opposite airbags 12 and 11, and the occupant seated in the intermediate seat 25 tries to move forward. In this case, the step portions 12b and 11b respectively support the projecting portions 11a and 12a on the other side, so that the overlapping portions of the airbags 11 and 12 are reinforced and resist the load of the occupant trying to move. Thus, the occupant's body can be firmly supported and the occupant is prevented from jumping forward through the abutting portions of the left and right airbags 11 and 12.

Although the seat provided with the intermediate seat is the rear seat of the passenger car in this embodiment, the airbag apparatus according to the present invention may be applied to a seat of the type provided with the intermediate seat in the front seat. Also, with respect to the seats of various vehicles such as airplanes and trains, if the seats are provided with intermediate seats, the protection of the occupants can be further secured by installing the airbag device of the present invention.
