Abstract: 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.

Abstract: PROBLEM TO BE SOLVED: To solve a problem wherein the protective function for an occupant in a rear seat is hardly degraded even when the positional relationship of a front seat to the occupant in the rear seat is changed. SOLUTION: In an airbag device for a rear seat, a controller 37 estimates a spacing between a back rest part of a front seat and knees of an occupant in the rear seat based on detected information by a front seat position sensor 32, a front seat collapse angle sensor 33 or the like. The controller 37 operates only a first inflator 15a when the estimated spacing is less than a predetermined value, and operates the first and second inflators 15a and 15b if the spacing is not less than the predetermined value. An airbag is developed and inflated thin by maintaining an overlapping part without breaking a tear seam part provided on an overlapping part of a tether when gas is supplied only from the first inflator 15a. The airbag is developed and inflated thick by breaking the tear seam part and developing the overlapping part when gas is supplied from the first and second inflators 15a and 15b.

Abstract: PROBLEM TO BE SOLVED: To enable accurate detection of sitting in response to the seated load, without regard to those placed on the seat cushion pad, with respect to the sitting detection apparatus installed in the seat of vehicle to detect seated state of occupants or the like. SOLUTION: This apparatus is equipped with a seat cushion pan 12A, a seat cushion pad 13A retained by this seat cushion van 12A, and a seated pattern sensor 14A that detects seated state of a sitter or the like on this seat cushion pad 13A, and the seated pattern sensor 14A is disposed between the seat cushion pan 12A and seat cushion pad 13A. Further there are provided at positions facing the detecting parts 20 provided on the seated pattern sensor 14A, projections 23 to make seated load collectively applied to the detecting parts 20.

Abstract: PROBLEM TO BE SOLVED: To improve the accuracy in the measurement of a weight of a seated occupant. SOLUTION: A sensor mounting board 44 with a sensor 62 is mounted on a sensor mounting part 40 of an upper rail 28 and a sensor mounting part 42 of a seat cushion frame 18, and the upper rail 28 and the seat cushion frame 18 are connected by a bracket 46 at a part opposite to the sensor mounting board 44, whereby the seat cushion frame 18 is downwardly moved when an occupant takes a seat, and a bent part 46C of the bracket 46 is downwardly compressed and deformed. Here, A vertical intermediate part 44A of the sensor mounting board 44 is curved to the outside in the seat width direction, and the sensor 62 detects the deformation at that time.

Abstract: 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.
