うに、矩形のエアバッグを用いている。2. Description of the Related Art An occupant protection device for a side collision of this type has an airbag built in a seat or a side door (side surface of a passenger compartment)
When a side collision (side impact) occurs, it is common to deploy the occupant between the side surface of the vehicle compartment and an occupant sitting on the seat to protect the occupant from a secondary collision with the side surface of the vehicle compartment. In this case, a rectangular airbag is used so as to cover the upper body from the chest to the head of the occupant, which is highly required to be protected.

ンク９が設けられている。First, the structure will be described. In FIG. 1, the occupant protection device 20 mainly includes a seat 1, an airbag module 7, and a link 9. Before the operation of the occupant protection device 20, the seat 1 is supported by a frame-shaped frame 8, and a cushion material 13 such as polyurethane is filled between the frame 8 and the outer skin 12. The side surface 2 of the seat 1 on the side door side (obliquely downward in the drawing) forms an independent body, which is movable from the two-dot chain line portion. Further, as will be described later, an airbag module 7 including an airbag, a gas generator and the like is installed at an upper corner portion of the frame 8 so as to form a part of the frame 8, and the main body is provided on the cracked surface. A link 9 that connects the side and the side surface portion 2 is provided.

The part 2 pivots diagonally forward around a fulcrum 10 provided at the lower corner of the frame 8. The rotation amount of the seat side surface portion 2 is regulated by a link 9, the tip of which moves forward by a distance D1 and laterally by a distance D2, and the upper half portion of the occupant 3
It is located laterally of the chest 5.

機構の構成が簡単になる。Next, the operation will be described. 1 to 3, when a side collision of a vehicle occurs, the airbag module 7 is activated by a signal from a collision detection unit (not shown),
The airbag 6, which is folded and stored in the module, is supplied with gas from a gas generator (not shown) and inflates. Then, the side surface portion 2 of the seat is pushed by the airbag 6 and cracks from the seat 1 to rotate obliquely forward around the fulcrum 10 (), and is restricted by the link 9 to stop at the position shown in the figure. On the other hand, the airbag 6 is also deployed at the position shown. Since the seat side surface portion 2 is filled with a cushioning material inside, the seat side portion 2 receives the chest portion 5 of the occupant 3 and serves as a cushion between the occupant side portion 11 and the occupant chest portion 5 to protect the occupant chest portion 5 from a secondary collision. To do. Further, the head of the occupant 2 is received by the airbag 6, and is similarly protected from a secondary collision with the side surface 11 of the passenger compartment. Thus, the chest 5 of the occupant 3 is protected by the seat side surface 2 and the head 4 is protected by the airbag 6, so that the capacity of the airbag 6 can be reduced and the airbag 6 can be smoothly deployed in a short time. Further, since the seat side surface portion 2 is rotated by utilizing the inflation of the airbag 6, the rotation of the seat side portion 2 can be interlocked with the inflation of the airbag 6 and can be operated in an extremely short time. The structure of the moving mechanism of the seat side surface portion 2 is simplified.

発明の効果を得ることができる。The above-described embodiment is merely an example, and the side collision passenger protection device of the present invention is not limited to this. That is, the seat side surface portion 2 in FIG. 2 may be configured not to rotate around the fulcrum 10 but to move in parallel, for example, a portion of the seat side surface portion corresponding to the occupant chest 5. Further, the seat side surface portion 2 in FIG. 2 may be rotated not by using the inflation force of the airbag 6 but by using an urging force such as a spring. However, in this case, trigger the spring etc. with a squib,
It must be configured to work with the airbag and operate in an extremely short time. Even with such a configuration, the effects of the present invention can be obtained as in the above.
