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 provide a pedestrian protective air bag device with superior internal pressure holding performance and unfolding performance. SOLUTION: An air bag body 26 is composed of a pair of left and right bag bodies 28 and 30, and the respective bag bodies 28 and 30 are formed as a hollow weave structure. In the pair of left and right bag bodies 28 and 30, a hollow weave end part 28A and a hollow weave end part 30A being a car width directional inside edge part are mutually sewn up (as a sewing-up part P) in the vehicle longitudinal direction. Gas introducing ports 28B and 30B are respectively formed in a vehicle longitudinal directional central part of the hollow weave end part 28A and the hollow weave end part 30A. COPYRIGHT: (C)2004,JPO

Abstract: An airbag for rear-end collision of a vehicle is accommodated in the interior of the vehicle while being folded in a state extending along a lateral direction of the vehicle. When supplied with gas, the airbag is inflated and deployed in a part of the passenger compartment rearward of the rearmost seat. The airbag has a supply port and a distribute section. The supply port permits gas to be supplied to the interior of the airbag. The distribution section is connected to the supply port. The distribution section distributes gas that has passed through the supply port end sections of the airbag in the lateral direction of the vehicle.

Abstract: PROBLEM TO BE SOLVED: To provide a method for folding an air bag for rear collision capable of enhancing a storing property against a vehicle and stability of deployment behavior and to provide an air bag device for rear collision capable of enhancing a protection performance against an occupant of the vehicle. SOLUTION: Both ends 13e of a crossing direction (direction of an arrow B in Fig. (a)) to a development direction (direction of an arrow A in Fig. (a)) of the air bag 13 itself are firstly folded to a central side of the cross section (first folding, Fig (a)). Then, the air bag 13 is folded such that an upper side part 13a and a lower side part 13b approach to each other (second folding, Fig. (b)). Subsequently, the air bag 13 is folded to a bellows shape between a connection part 41 and a swirl part 13f to form a bellows folding part 13g (Fig. (c)). COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide a posterior seat crew's protection device in a vehicle capable of realizing the protection by preventing a rearward movement of the crew seated on the most posterior seat when a rear collision occurs in the vehicle. SOLUTION: A tension imparting part 21c is formed on both right and left side parts of an air bag 21 provided corresponding to a rear window glass 18 at a rear end of the vehicle 10 such that it is downwardly prolonged and a lower end of this tension imparting part 21c is fixed to a fixing member of the vehicle. When a gas is fed into the air bag 21 from an inflator 22, the air bag 21 is expanded/developed between tension imparting points 31, 32 with a predetermined tension. Therefore, even if the crew seated on the rear seat is rearwardly and upwardly moved along a backrest by an impact of the collision accident of the vehicle, the movement is prevented by the air bag 21.

Abstract: PROBLEM TO BE SOLVED: To provide an airbag system capable of certainly inflating and expanding an airbag in a suitable direction, effectively absorbing impact at vehicular collision, and easily returning the airbag that has not been inflated and expanded to its original position when avoiding collision. SOLUTION: The airbag 31 is installed to a center portion of a steering wheel 21. When a pre-crash sensor estimates and detects collision, the airbag that has not been inflated and expanded is moved to a predetermined position by actuation of a moving motor 37, thereby changing a direction of the airbag 31. Then, when a collision sensor detects the collision, the airbag 31 is inflated and expanded at the predetermined position by actuation of an inflator 32. When the collision sensor does not detects the collision, the airbag 31 that has not been inflated and expanded is returned to its original position by actuation of the moving motor 37.
