Abstract: PROBLEM TO BE SOLVED: To protect the knee section of an occupant on a rear seat more effectively regardless of a relative position of an airbag module mounted ahead of the rear seat to the occupant on the rear seat. SOLUTION: When it is judged that an impact larger than a prescribed magnitude may be applied to a vehicle from the front side, a controller controls an actuator 17 to adjust the position to a front seat 10 of an airbag module 12 provided on the front seat 10 so that a distance between the airbag module 12 and the knee Pk of the occupant P in the rear seat may be a predetermined one. An actuator 24 for actuating a reaction plate 14 is controlled to tilt backward the reaction plate 14 provided at the back of a backrest 13, thus adjusting the distance between the reaction plate 14 and the knee Pk to a prescribed one.

Abstract: PROBLEM TO BE SOLVED: To provide an occupant protection device capable of enhancing restriction force of a seat belt in collision of a vehicle. SOLUTION: The airbag device 20 is provided with an airbag 22 stored on a connection part 8b of a buckle 8 in a case 23 in the folded state and deployed in collision of the vehicle. Further, the airbag 22 is deployed so as to fill a space formed between a lap belt part 6b, the buckle 8 and a sitting part 2 of a seat 1 in collision. COPYRIGHT: (C)2007,JPO&INPIT

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.
