Abstract: The airbag apparatus for a front passenger's seat includes an airbag provided on its rear side with a protection portion contactable with a passenger. The airbag internally includes a vertical tether for controlling the contour of the airbag upon inflation depending on a passenger. The protection portion includes each one left and right shoulder restraining portion disposed side by side along the lateral direction for contact with left and right shoulders of the passenger. The vertical tether works to vary a distance between the shoulder restraining portions in the lateral direction at the complete airbag inflation into a wide distance correspondent to a large passenger and a narrow distance correspondent to an undersized passenger.

Abstract: A knee-protecting airbag apparatus includes an airbag folded and housed in the lower side of column cover. Airbag is attached to a housing with inflator at a position in its column cover side wall which wall is deployed toward column cover upon airbag inflation. When folded and housed in the housing, airbag is folded in such a manner as to turn a boundary region of driver's side wall and column cover side wall, which region is deployed forward of inflator at the complete inflation of airbag, in between inflator and driver's side wall to reduce the longitudinal width of airbag.

Abstract: The airbag apparatus includes an airbag having an exhaust hole for discharging part of inflation gas, an open/close controller for controlling opening and closing operations of the exhaust hole, and a flap element releasably joined to the open/close controller and being joined to a periphery of the exhaust hole in an outer side of the airbag which periphery is in a side facing away from the open/close controller, for opening and closing the exhaust hole. The apparatus further includes an open/close means arranged in the periphery of the exhaust hole. Upon airbag inflation, if the flap element is retained by the open/close controller, the open/close means is held down at its outer side by the flap element and keeps the exhaust hole closed. If the flap element is released from the open/close controller, the open/close means opens by the pressure of inflation gas to expand an opening area of the exhaust hole.

Abstract: An open-looped rim portion which results when an upper part thereof is open is provided on a steering wheel, and airbags of an airbag apparatus are accommodated in a pad portion lying inside of the rim portion. Then, when an impact of a predetermined value or greater is applied to a front end of a vehicle, the individual airbags are deployed by injecting the gas from an inflator. In addition, when an occupant is captured by the first airbag which is so deployed, the second airbag applies a reaction force which is directed to the rear of the vehicle so as to resist a pressure applied to the first airbag by the occupant.

Abstract: A steering wheel is securely mounted on a bracket which is fixed to a reinforcement of a vehicle via a rod which extends along a longitudinal direction of the vehicle in such a manner as to move relatively thereto. A bellows-like member is interposed between a seat portion of the rod and the bracket, so that the bellows-like member is contractible along the longitudinal direction of the vehicle when a predetermined magnitude of impact is applied to the steering wheel from a rear side of the vehicle by an occupant who is caused to move forwards in association with the application of an external force from the front of the vehicle due to the vehicle being involved in a frontal collision or the like, whereby the impact so applied to the steering wheel is absorbed by the bellows-like member.

Abstract: The airbag of the present invention, when completely inflated, is formed into a generally square conical shape whose top is in a front end of the airbag. A protection portion to be located in rear side of the airbag upon airbag inflation includes shoulder restraining portions disposed generally side by side in left-right orientation in an area from upper part to rear part of the completely inflated airbag. Each of the shoulder restraining portions continuously projects in upper part to rear part of the airbag.

Abstract: The airbag device for front passenger's seat of the present invention includes an airbag protruding and deploying from an opening for protrusion in instrument panel in front of front passenger's seat when activated. The airbag includes a bag-shaped airbag body constituting outer wall of the airbag, and a flow regulating cloth disposed inside the airbag body. The flow regulating cloth inflates firstly upon inflow of inflation gas, and redirects the gas before supplying the same to the airbag body for promoting deployment of the airbag body. The flow regulating cloth includes a circumferential wall provided with left and right gas outlet ports for emitting gas outward in left and right directions. When the airbag is inflated, parts of the circumferential wall of the left and right outlet ports project from the opening in instrument panel in left-right direction, such that the parts deploy above top face of the instrument panel in a periphery of the opening.

Abstract: An airbag device for front passenger's seat of the present invention includes an airbag folded and housed in a case. A rear side face of the airbag as completely deployed confronts an occupant and serves as a restraint face. The airbag includes an upper inflatable portion and a lower inflatable portion arranged vertically at airbag inflation. Rear side faces of each of the upper and lower inflatable portions define upper part and lower part of the restraint face. A lower wall of the upper inflatable portion and a top wall of the lower inflatable portion contact and overlap with each other as the airbag is completely inflated, and contacting face of the top wall and the lower wall is wide enough to stay contacted even when either the upper inflatable portion or the lower inflatable portion restrains a part of occupant.

Abstract: An air bag apparatus having a constitution of developing an air bag folded to contain in a case to a rear side of a vehicle by making an expanding gas flow from a gas flow inlet in expanding to develop the air bag. The air bag is arranged with a through hole. The air bag is constituted by a ring-like member arranged with a lower expanded portion arranged with a gas flow inlet, an upper expanded portion arranged to an upper side of the lower expanded portion to communicate with a front side of the lower expanded portion, and a rear expanded portion arranged to connect to a rear part of the lower expanded portion and a rear part of the upper expanded portion at a surrounding of the through hole. The air bag is constituted to finish to expand by closing the through hole.

Abstract: In an airbag device (10) wherein within a casing (12) opening upwardly an inflator (16) and an airbag (14) are housed at its bottom part and the opening side, respectively, a cylindrical diffuser (18) surrounding the outer circumference of the inflator (16) is provided, which has a partition wall (40) projecting toward the opening side of the casing and partitioning an airbag-housing space into a forward side and a rearward side relative to the vehicle, in which to house the airbag (14) dividedly, and a lip portion (32) of the airbag (14) is superposed downwards of the diffuser (18) thereby to lock the bottom part of the diffuser (18) to the bottom surface of the casing (12). Thus, it is easy, albeit compart, to control the deployment behavior of the airbag and excellent in workability of assembling the airbag in the casing.

Abstract: An air bag device has an air bag at least partially receivable in a predetermined receiving part of a vehicle along with an inflator for inflating the air bag. A band is breakable by a deployment pressure of the air bag and is provided such that at least a part of the air bag is strapped by the band to retain a folded shape prior to deployment of the air bag. The band is formed of a woven fabric in an embodiment and includes a breaking part formed by breaking assisting structure arranged in a line corresponding to a breaking direction of the breaking part. In an embodiment of the air bag device the woven fabric has weaving thread inclined at an inclination angle with respect to the breaking direction of the breaking part.
