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.

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 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.
