Abstract: An airbag for a steering wheel is configured to cover an upper surface of the steering wheel generally all over when inflated. The airbag includes a driver-protection portion that is configured to be deployed towards a driver's seat and restrain a driver, a central protruding portion that is disposed in a vicinity of a center of the driver-protection portion and protrudes towards the driver's seat, a circumferential protruding portion that is disposed in a vicinity of an outer circumferential edge of the driver-protection portion and protrudes towards the driver's seat, and a small protruding portion that is disposed between the central protruding portion and circumferential protruding portion and protrudes towards the driver's seat. The small protruding portion is smaller in protruding amount than the central protruding portion and the circumferential protruding portion.

Abstract: A method of folding is provided for folding an airbag including a vehicle-side wall, a driver-side wall, an inlet opening formed in the vehicle-side wall and a mounting seat disposed in a periphery of the opening. The method includes a first process conducted in a first direction and a second process conducted in a second direction orthogonal to the former. The first process includes an initial folding that folds back each of opposite sides in the first direction of the airbag as flattened with respect to the mounting seat towards the mounting seat, a rolling that rolls the airbag towards the mounting seat from creases formed in the initial folding, and an invaginating that invaginates each of resulting rolled regions between the vehicle-side and driver-side walls. The second process folds up opposite sides in the second direction of the airbag with respect to the mounting seat each towards the mounting seat.

Abstract: An airbag includes a mounting portion, a top wall deployable towards a vehicle occupant, and a circumferential wall disposed between the mounting portion and top wall. An airbag base member for forming the airbag includes a top-forming panel for forming the top wall, and at least three circumferential panels that extend generally radially from the top-forming panel and form the circumferential wall by being joined together by adjoining edges thereof. Each of the circumferential panels is formed into a generally band-like contour which has a first and a second curving edges that make the circumferential panel enlarge in width from the leading end towards an intermediate portion and then narrow towards the top-forming panel. When the airbag base member is laid flat, adjoining edges of any two adjoining circumferential panels are generally symmetrical to each other in curving shape with respect to a line disposed there between.

The roof airbag includes a roof airbag that is inflatable and deployable downwardly between the front airbag and the front seat for protecting a head of the occupant when an impact is applied to the vehicle from forward.

Abstract: An airbag is formed by joining outer edges of an occupant-side wall and a vehicle-side wall each of which is made of a base cloth having flexibility. The occupant-side wall and vehicle-side wall are equal in circumferential length of the outer edge. The occupant-side wall includes a recessed region for receiving a head of a vehicle occupant and an annular raised region that surrounds the recessed region. At least one of the occupant-side wall and the vehicle-side wall includes at least one shortening region that reduces a circumferential length of an outer edge of the base cloth.

Abstract: An airbag for steering wheel is configured to inflate so as to cover an upper surface side of a ring part of a steering wheel. Outer peripheral edges of a vehicle body-side wall part and a driver-side wall part are joined such that the airbag is formed to have a bag shape, and an inlet opening is arranged at a vicinity of a center of the vehicle body-side wall part. The vehicle body-side wall part is formed with a concave part to be concave upward toward the driver-side wall part upon completion of the inflation so that a rear part-side region of the ring part can be entered into the concave part, and the concave part is arranged at the vehicle body-side wall part so that the ring part is entered into the concave part when a driver is received by the airbag upon completion of the inflation.

Abstract: A vehicle seat with a side airbag apparatus includes a seat back having a seat frame, a side airbag apparatus having an airbag and an inflator, and an entry preventing portion. The seat frame includes a pressure receiving plate and an outer frame portion, which surrounds the pressure receiving plate. The airbag and the inflator are installed in the outer side section of the seat back. The airbag includes a main inflation portion and an auxiliary inflation portion. The auxiliary inflation portion is inflated on the front side of the pressure receiving plate prior to inflation of the main inflation portion, thereby pushing the occupant toward the inner side. The entry preventing portion prevents the auxiliary inflation portion being inflated from entering the gap between the outer frame portion and the pressure receiving plate.

Abstract: A steering wheel airbag, arranged to cover a steering wheel when inflation is completed, includes: a front-collision receiving surface which is arranged on a side of a driver when inflation is completed, so as to receive the driver moving forward during a head-on collision of a vehicle, the front-collision receiving surface being arranged substantially along a vertical direction to be tilted with respect to a ring surface of the steering wheel when inflation is completed; and arm restraining parts which are arranged near arms of the driver steering a ring part of the steering wheel on both right and left sides of the front-collision receiving surface when inflation is completed, the arm restraining parts coming into contact with the arms during an oblique collision or an offset collision of the vehicle, so as to prevent a movement of the driver to an obliquely front side.

Abstract: An airbag includes a main inflation portion, in which an inflator is arranged, and an auxiliary inflation portion, the volume of which is smaller than that of the main inflation portion. The main inflation portion is deployed forward in a space between an occupant and a side wall of the vehicle. Prior to the deployment of the main inflation portion outside the seat back, the auxiliary inflation portion is inflated inside the seat back with inflation gas from the inflator to push the occupant toward the inner side. The main inflation portion and the auxiliary inflation portion each have a communication port that connects the main inflation portion and the auxiliary inflation portion to each other. The airbag includes an inflation promoting structure, which promotes the inflation of the auxiliary inflation portion compared to the inflation of the main inflation portion.

Abstract: An airbag is inflatable in such a manner as to separate a vehicle-side wall which is deployable towards a vehicle body structure and an occupant-side wall which is deployable towards an occupant for catching the occupant. The airbag is configured to be supported by the vehicle body structure on the vehicle-side wall when catching the occupant with the occupant-side wall. The airbag includes a recessed section on left and right sides of and in a vicinity of the center of the occupant-side wall and a tether that connects the bottom of the recessed section to the vehicle-side wall in order to form the recessed section. Opposing walls of the recessed section press each other in a separable fashion when the airbag is inflated. The tether allows gas communication between a central region of the airbag and a peripheral region of the airbag which surrounds the central region, inside the airbag.

Abstract: A lateral partition of a side airbag apparatus extends in a front-rear direction to divide the interior of an airbag into an upper inflation chamber and a lower inflation chamber. A vertical partition extends vertically and includes a communication portion. The vertical partition divides the upper inflation chamber into an upper-rear inflation chamber, to which inflation gas from a gas generator is supplied, and an upper-front inflation chamber, to which the inflation gas is supplied via the communication portion. An inner tube regulates the flow of the inflation gas to direct to the upper-rear inflation chamber and the lower inflation chamber. The rear ends of two first fabric portions of the vertical partition are joined to the upper parts of the front ends of two second fabric portions of the inner tube by a first vertical joint portion.
