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 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 effectively protect knees and lower portions thereof, mainly foot tips of occupants seated in a rear seat. SOLUTION: In the airbag device for the rear seat, an airbag 16 which is developed and inflated between a front seat 11 and a rear seat 15 is stored in a case 13 of an airbag module 10 fixed to a lower side of a seat part 12 of the front seat 11. The airbag 16 comprises an upper inflation part 22 which is developed and inflated along a back rest part 21 of the front seat 11, a lower inflation part 23 to cover a space between the seat part 12 and a floor F. A support guide 24 to support a front face 23a of the lower inflation part 23 is provided on a lower side of the case 13 between the seat part 12 and the floor F. The lower inflation part 23 is brought into contact with the floor F. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To improve outer appearance quality of a lower leg constraining device arranging part on an instrument panel and to prevent damage of the lower leg constraining device at the time of working. SOLUTION: A shear line 36 to break at the time when an active knee bolster 24 works is formed on the instrument panel 18, and the shear line 36 is provided at a position to break an area larger than a lower leg constraining surface 35 including the lower leg constraining surface 35 on the main body 30 of the active knee bolster 24. A thick part 40 is formed along the shear line 36 in the inner peripheral part of the shear line 36 and a recessed part 42 is formed along the thick part 40 in the inner peripheral part of the thick part 40 on the side of a back surface 18B of the instrument panel 18.
