摘要： PROBLEM TO BE SOLVED: To provide a vehicle mounting structure of an airbag device for rear-end collision, restraining a ceiling of a cabin from being lowered. SOLUTION: An airbag 11 is mounted on the vehicle in the state where it is folded in a vertical direction and both left and right end parts 11a are folded/returned to left and right inner sides. The folded/returned portion to the left and right inner side of the airbag 11 then becomes thicker as compared with the other portion of the airbag 11. However, a back door hinge 61 is provided in a position different from the folded/returned portion to the left and right inner sides of the airbag 11 in a vehicle width direction. The ceiling of the cabin is made higher thereby, as compared with the case where the back door hinge 61 is provided above the portion folded/returned to the left and right inner sides of the airbag 11.

摘要： PROBLEM TO BE SOLVED: To provide an occupant protection device which prevents a submarine phenomenon without impairing sitting comfort. SOLUTION: A substantially regular hexagonal cylindrical storage cylinder 34 is stored in a storing recess 21 provided at a bottom frame 19 of a seat 12. An inflator 24 as a gas generating source is stored in the storage cylinder 34. The storage cylinder 34 is incorporated into an air bag 25 made of fabric. The cylindrical inflator 24 is screwed on a bottom wall 26 for forming the storing recess 21. A supporting surface 342 to be one of 6 planes to be outer peripheral surfaces 340 of the storage cylinder 34 is parallel to an upper surface 192 of a supporting wall 190. A height position of the supporting surface 342 is set to be a position slightly lower than the upper surface 192. The supporting surface 342 faces a lower surface 332 of a seat cushion 33.

摘要： PROBLEM TO BE SOLVED: To provide a child seat detection device and a child seat detection method capable of accurately judging whether or not a child seat is installed on a vehicle seat with a simple constitution. SOLUTION: A seat sensor 44 constituted by a plurality of cells 46 for partitioning a whole surface area of a seat cushion 40 to a constant area is buried near a surface in the seat cushion 40 of a vehicle seat 10. The respective cells 46 of the seat sensor 44 are so constituted that a current corresponding to a load flows when the load of a predetermined value or more is applied. In the case where CRS is installed on the vehicle seat 10, since the CRS is certainly fixed to the vehicle seat 10 by a seat belt, a load distribution applied to the vehicle seat 10 is maintained to an approximately constant value even if a lateral acceleration Gr of a predetermined value or more is generated in the vehicle. Accordingly, in the case where a lot of cells 46 in which a load Wij is largely varied in a reduction direction do not exist under the circumstance that the lateral acceleration Gy of a predetermined value or more is generated in the vehicle, it is judged that the CRS is installed on the vehicle seat 10.
