Abstract: A side airbag apparatus for vehicle has an airbag and an inflator. An upper chamber, a lower chamber, and an intermediate chamber are defined by a seam in the airbag. When the airbag is deployed, the upper chamber corresponds to a shoulder of an occupant, the lower chamber corresponds to a lumbar region of the occupant, and the intermediate chamber corresponds to a thorax of the occupant. The seam guides gas from the inflator to the upper and lower chambers such that the upper and lower chambers are substantially simultaneously inflated, and the intermediate chamber is inflated after a delay. The thickness of the intermediate chamber is less than the thicknesses of the upper and lower chambers. As a result, the occupant of the vehicle is effectively protected.

Abstract: An air bag is stored in the upper fringe of the openings on the cabin-inside side, while being folded. The air bag includes a gas inflow part for flowing inflation gas into the air bag, and a main body that inflates when receiving the inflation gas. The main body includes front- and rear-seat inflation chambers, and a gas passage extending forwardly from the gas inflow part and allowing the inflation gas to flow from inflow ports opened in the upper parts of the front- and rear-seat inflation chambers to the front- and rear-seat inflation chambers per se. The inflow port of the rear-seat inflation chamber is opened in a direction substantially orthogonal to an axial direction of the gas passage. A front-side peripheral edge is disposed to be higher than a rear-side peripheral edge.

Abstract: In a head protecting airbag device, an airbag includes an inflation portion and a connection port portion. The connection port portion includes: an outlet side portion having a communication port to the inflation portion at its lower end; and an inlet side portion for inserting an inflator therein. The inflator includes a body portion having a gas discharge port, and a diffuser having a gas outlet port. The diffuser is connected with the body portion so as to cover the gas discharge port, having its two ends forced into contact with the outer circumference of the body portion. The inflator is connected to a connection port portion with good sealing properties and the gas outlet port faces toward the communication port of the connection port portion and thus toward the inflation portion. This head protecting airbag device simplifies the connection structure between the inflator and the airbag while retaining the quick expansion and inflation of the airbag.

Abstract: An occupant restraining device (S1) comprises a shielding member (51F) and an airbag (104F). The shielding member (51F) in action is so let off from the peripheral edge (DW) of a window (WF) of a vehicle as to shield the window. The airbag (104F) in action is expanded and inflated from the peripheral edge (UW) of the window that it can be interposed between the shielding member (51F) and an occupant (M). The airbag (104F) allows the side of the lower end (105b) at the time of completion of the expansion and inflation to move in the direction generally perpendicular to the window (WF). Even if the occupant (M) is close to the window (WF), the expanded and inflated airbag (104F) is smoothly interposed between the occupant (M) and the window (WF).

Abstract: A head protecting airbag device comprising an airbag folded and housed above the upper edge of a window inside of a vehicle and expanded while being extended to cover the inner side of the window when it admits an inflating gas. The airbag includes a body portion and an extension portion. The body portion covers the inner side of a side window positioned on the side face of the vehicle. The extension portion is arranged on at least the front end of the body portion, and extends on the inner side generally perpendicular to the side window. Moreover, the extension portion is formed into a sheet shape having flexibility such that it can be arranged in front of a passenger upon completion of the expansion of the airbag. Moreover, the body portion is fixed at its upper edge upon completion of the expansion on the body side while allowing the lower edge upon completion of the expansion to move generally perpendicular to the side window.

Abstract: A passenger's seat airbag device of the invention is mounted on a vehicle such as a single-cab vehicle in which a rear wall portion is so arranged on the rear side of a side window as to intersect the side window generally perpendicularly. The airbag device includes an airbag which is so folded and housed on the upper edge side of the side window on the interior side as to cover the side window at its extending and expanding time. The airbag is mounted on the vehicle body on its two longitudinal ends. The rear side leading end is mounted on a position of the rear wall portion away from the vehicle side face. In the vicinity of the corner portion of the vehicle, there is arranged guide means which can guide the downward protrusion of the airbag when the airbag is extending and expanding and can regulate the movement of the airbag to the interior side when the airbag is extending and expanding.

Abstract: An air bag is stored along the peripheral edge of the upper fringe of an opening on the indoor side in a state that it is covered with a door of an air bag cover and folded. When receiving inflation gas, the air bag forcibly opens the door and develops and inflates downward so as to cover the opening. In a region of an inflating section to which gas for inflation flows, a plurality of thickness defining members, which couple the cabin-inside side wall with the cabin-outside side wall to make a thickness of the inflating section uniform, are arranged side by side in the front/rear direction, while extending in the vertical direction. The thickness defining member disposed near the unsmooth development part of the door is disposed such that the upper end thereof is located at a position lower than the upper end of the thickness defining member.

Abstract: An airbag including an expansion part accommodating inflow of expansion gas to expand a peripheral wall, and linear joining portions arranged in a region of the expansion part and constituted by joining facing portions of the peripheral wall in a linear manner. The linear joining portions include a linear base, curved portions and swelling portions. Each of the curved portions is connected to the base and curvilinearly extends and bends toward the respective base thereof. The swelling portions are arranged at tip ends of the curved portions to smoothly connect outer peripheral edges thereof to outer peripheral edges of the curved portions. With this airbag, stress concentration is reduced around the swelling portions and the curved portions at the time of development and expansion. Thus, the linear joining portions can be arranged without causing breakage of the peripheral wall during development and expansion, and reduction in volume and expansion area held down as much as possible.

Abstract: To reduce damaging of an inner tube in the vicinity of a gas ejection port of an inflator. To the peripheral portion near an end on a gas ejection port side of an inflator, one end of a pipe is fixed. The pipe extends in the axial direction of an inner tube having such flexibility as a cloth, is smaller in the diameter, shorter and higher in rigidity than the inner tube. In the pipe, its leading end is thinner than a part that is an outer portion of the gas ejection port of the inflator. Further, at the peripheral portion of the end of the pipe, a rear-leading end of the inner tube is clumped-by a clump.

Abstract: An air bag for a head protection air bag system has an air bag main body and an inner tube disposed along an upper edge side within the air bag main body. The inner tube has supply ports which are made to open on a lower side of a circumferential wall thereof for supplying the inflating gas into the air bag main body, and the supply ports are disposed in such a manner as to be made to open downwardly at a substantially transverse center of the folded air bag main body when the air bag main body has been folded up. At least the supply port of the inner tube disposed in the vicinity of the inflator is offset closer to the inflator side than the transverse center of an inlet port portion communicating with the supply port.

Abstract: In a head protection air bag device, a folded air bag receives inflation gas, and when its inflating operation is completed, inflation parts of front and rear inflatable protective shielding parts as partitioned by partitioning parts generate tensions in the longitudinal direction in the front and rear inflatable protective shielding parts per se. The front and rear inflatable protective shielding parts are interconnected to each other by inflation communicating part under a plate-like portion which blocks the inflow of the inflation gas, at the lower fringe side of the air bag. The inflation communication parts are longitudinally disposed along the lower fringe side of the air bag. Therefore, the front and rear inflatable protective shielding parts are interconnected without reducing the tensions in those parts. As a result, a high tension having the longitudinal direction is generated in the entire lower fringe of the air bag.
