    Abstract: PROBLEM TO BE SOLVED: To quickly constrain knees of an occupant also when lower limbs of the occupant are close to a glove door when an airbag door includes a lower side door deployed to at least a vehicle lower side. SOLUTION: This airbag door 54 includes an upper side door 54 and the lower side door 54B, and is deployed in the vehicle vertical direction when deployed. In the center at a rear face side of the lower side door 54B, a groove 100 is formed along the vehicle width direction. Thus, when the lower side door 54B is deployed to the vehicle lower side and hits on shanks of the occupant, the lower side door 54B passes through the groove 100 while bending. As a result, the knee airbag 86 can be prevented from being inflated and deployed with a delay. COPYRIGHT: (C)2010,JPO&INPIT

    Abstract: A knee airbag device for a vehicle, configured in such a manner that, when a knee airbag is inflated and expanded with the knees of a vehicle occupant located close to an airbag door, a load to the lower legs is reduced. A first tear section (100) for expanding a first airbag door (108) in the vehicle's top-bottom direction and a second tear section (102) for expanding a second airbag door (112) in the vehicle's lateral direction are formed on the rear surface side of a glove-box-door outer member (24). The first tear section (100) is composed of a left and right pair of vertical tear sections (104) and a first horizontal tear section (106). The second tear section (102) is composed of second lateral tear sections (110).

    Abstract: PROBLEM TO BE SOLVED: To secure gas cooling performance and mist removing performance in a disk type inflator, and to reduce size and weight of the inflator in the radial direction. SOLUTION: An inflator case 40 is constituted of an upper case 36 arranged on an occupant side and a lower case 38 arranged on an anti-occupant side. In the inflator case 40, a cylindrical holding member 60 having a bottom part constituted of a bulkhead 64 is arranged. A gas flow passage 74 is formed around the holding member 60. A communication hole 80 communicating with the gas flow passage 74 is formed in the bulkhead 64. Dimples 81 are formed on inside surfaces of bottom wall part 38A and inclined part 38B of the lower case 38. Turbulent flows R therefore are generated at forming portions of the dimples 81 when gas flows in the gas flow passage 74. The gas of a high temperature can be effectively heat-exchanged and mist 82 can be effectively removed, and thereby a conventional filter can be abolished. COPYRIGHT: (C)2009,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a side airbag device of a vehicular seat capable of mounting even a large airbag unit to a side frame of a seat back and securely developing an airbag forward in the development. SOLUTION: Inside a side part of the seat back 1 on a door side, the airbag unit 4 including the airbag 40 folded in a longitudinally long manner is provided along the side frame 2 of the seat back 1. Upon side collision of the vehicle, the airbag 40 is expanded/developed forward outside the seat to protect an occupant. In such a side airbag device 3 of a vehicular seat, between the airbag unit 4 and the side frame 2, a guide plate 5, which is a longitudinal plate having the same vertical length as that of the airbag unit, for guiding the expanding/developing direction to the front in operation of the airbag 40 is installed so as to lay its plate surface along the longitudinal direction.

    Abstract: PROBLEM TO BE SOLVED: To provide a side airbag system capable of deploying a side airbag forward of a vehicle as a regular deployment direction thereof, without increasing the number of parts. SOLUTION: A plate 58 is joined at a position facing an deployment area of a side airbag 18 at a seat back pad side 24, and a gap 62 is provided between a rear end 58B' and a front bent part 22C of a seat back frame side 22. Thereby, at the initial stage of deployment of the side airbag 18 (prior to burst of a second seamed line 40), a partial part 18C of the side airbag 18 is put inward in the vehicle width direction from the gap 62 and the rear part 58B of the plate 58 is depressed in the direction of arrow mark A. Accordingly, the front part 58A of the plate 58 is extruded in the direction of arrow mark B. Thus, the side airbag 18 can be deployed in the front of the vehicle by preventing it from deploying in the vehicle width direction. COPYRIGHT: (C)2008,JPO&INPIT

    Abstract: It is an object to ensure that, even when knee regions of an occupant are in a near state with respect to a storage section of a knee airbag at the time of a frontal collision of a vehicle, the knee regions can be restrained appropriately by the knee airbag. A knee airbag 14 stored in a folded state in a glove box door 22 (a storage section) receives a supply of a gas at the time of a frontal collision of a vehicle 18 and inflates and deploys toward knee regions 36K of an occupant 36 seated in a front passenger seat 12 (a vehicle seat). At this time, when the knee regions 36K of the occupant 36 are in a near state with respect to the glove box door 22, the gas inside the knee airbag 14 becomes ventable to the outside from a vent hole 16. The vent hole 16 appropriately vents this gas from the inside of the knee airbag 14, and the reaction force of the knee airbag 14 with respect to the knee regions 36K are reduced.
