  • Patent number: 8408589
    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).

  • Patent number: 8308189
    Abstract: A knee airbag is provided to the lower part of a glove box door, and an airbag door provided to the glove box door opens in both upward and downward directions when the knee airbag expands. As the knee airbag expands, the rigidity of the lower part of the glove box door decreases, and this causes a relatively small reaction force, which corresponds to a relatively small load generated when the knees of an occupant having a relatively small body build make contact with the lower part, to be generated on the lower part of the glove box door. On the other hand, because the knee airbag is not provided to the upper part of the glove box door, the upper part can generate a relatively large reaction force which corresponds to a relatively large load generated when the knees of an occupant having a relatively large body build make contact with the upper part via the knee airbag.

  • Patent number: 8292323
    Abstract: A load on the shins when a knee airbag is deployed by inflating in a state in which the knees of an occupant are proximate to an airbag door or suchlike is moderated. Inside a knee airbag, an upper tether and a lower tether are disposed to sandwich an inflator from above and below. First opening portions and second opening portions for letting gas flow through up and down are alternatingly formed in the upper tether and the lower tether. The second opening portions are formed as circular holes with smaller diameters than the first opening portions. The second opening portions are disposed at positions opposing the knees of a small occupant in a sitting state.

  • Patent number: 8262126
    Abstract: A casing 53 is coupled to an air bag door 40, and an air bag reaction force is loaded on the air bag door 40 via the casing 53. Since the general portion 42 of the air bag door 40 is fixed to the tear line outer portion 23 of the glove door outer member 20 at the cabin-side surface 42a and is fixed to the glove door inner member 30 at the opposite cabin-side surface 42b, the reaction force of the air bag loaded on the air bag door 40 can be borne by not only the fixing strength between the general portion 42 of the air bag door 40 and the tear line outer portion 23 of the glove door outer member 20 but also the glove door inner member 30 until the air bag 51 expands to break the tear portion 21. As a result, the fixing portion between the general portion 42 of the air bag door 40 and the tear line outer portion 23 of the glove door outer member 20 is prevented from being broken.

  • Patent number: 8235414
    Abstract: In a glove door-installed knee air bag apparatus, a stud bolt of an inflator is fixed to an inflator supporting member in a state that the stud bolt is inclined in a vertical direction relative to a general plane of a glove door inner member. Due to the structure, a thickness W0 of an air bag module measured at the inflator installing portion is made small. The inflator supporting member includes a first portion and a second portion. In a case where a hook portion is formed in the first portion, the number of parts can be reduced. In a case where the inflator is located at a lower portion of a housing space, a handling force for opening and closing the glove door is light. In a case where the first portion comprises a bottom wall of the air bag casing and the second portion comprises a side wall of the air bag casing, the number of parts is reduced.
