An airbag comprises a front panel (22), a rear panel (24) and an additional panel (26), the front panel (22) and the rear panel (24) being directly connected to each other in a first circumferential portion (28) and the front panel (22) being connected to the additional panel (26) and the additional panel (26) being connected to the rear panel (24) in a second circumferential portion (30).

Further, an airbag module (16), a vehicle (10) and a method of manufacturing the airbag (18) are shown.

An assembly includes a seatback. The assembly includes a side airbag supported by the seatback and inflatable to an inflated position including a top panel having a pair of opposing side edges and a front edge extending between the side edges. The side airbag includes a main panel fixed to the top panel at a seam extending along the side edges and the front edge.

A non-coated air bag fabric is a fabric constituted by synthetic fibers, and the fabric has a cover factor of 2300 or more, a height difference between a recess and a protrusion on a surface of the fabric is less than 130 m, and a P ratio expressed by the following equation is 0.85 to 1.15 inclusive. The P ratio=HP.sub.100/HP.sub.80 where HP.sub.80 indicates air permeability after a load is applied to the fabric under a condition of 80 C., and HP.sub.100 indicates air permeability after a load is applied to the fabric under a condition of 100 C.

An airbag for a passenger seat adapted to be stored in a storage which is disposed in an instrument panel in front of a passenger seat is disclosed. The airbag includes a passenger-side wall which is disposed in a rear portion of the airbag as deployed for arresting a passenger, and a vehicle-side wall that extends from an outer circumferential edge of the passenger-side wall towards a front end of the airbag as deployed in a narrowing fashion for mounting on the storage by the front end. The vehicle-side wall includes a recessed area for circumventing an adjoining object disposed in the vehicle when deployed. The recessed area is composed of a tuck formed in a base member of the vehicle-side wall. The tuck is formed by jointing one or more pair of tuck jointing portions that are distant from one another in the base member as laid flat.

Provided is an airbag which can be easily manufactured though it is provided with a tether inside, and has a reduced fear of gas leakage from a joint region. The airbag includes a joint region of outer circumferential edges of a pair of walls. The joint region includes, between the outer circumferential edges of the pair of walls, a sealing member which has elasticity, and has adhesiveness in an unsolidified state. The joint region is formed by such a sewing that runs a sewing thread through an application area of the sealing member. A tether connects the pair of walls. The joint region includes a region in which the sealing member has a solidified, thus non-adhesive surface, and is pressed against at least one of the walls by the non-adhesive surface, and penetrated by the sewing thread in that state.

An automotive interior component with an airbag door includes: a core member covering a front pillar and including a hinge part; and a surface member stretched so as to cover a front surface of the core member. The airbag door is a site of the core member partitioned by the hinge part which site is capable of abutting on an airbag. The surface member includes a fold part extending to an outer edge side of a rear surface of the core member so as to cover an edge part connecting between the front surface and the rear surface of the core member. The fold part includes a first fold part not crossing the hinge part and positioned on the airbag door side, and a second fold part bent from the first fold part and crossing the hinge part. The first and second fold parts are stitched with a thread.

An airbag device for a passenger seat having an inflator and an airbag, wherein: the airbag includes a first structural portion that structures a left-right direction intermediate portion of the airbag and at which is formed a first surface, and second structural portions that are formed in continuation with both left and right sides of the first structural portion and at which are formed a pair of respective second surfaces that is to bulge further toward the front passenger seat side than the first surface and move apart from one another, and a connecting cloth, which connects regions that become bulging end portion sides of the pair of second surfaces in an inflated and deployed state of the airbag, and which is deployed to cover a range that is reached by the head portion and the chest portion of the passenger in the front passenger seat, is provided.

Problem: To effectively suppress movement toward a collision site of an occupant even when the occupant is seated only in the driver's seat.

Resolution Means: a side airbag device 1 provided on a side surface portion on the center side in the width direction of the backrest SB of the seat s of one of the driver's seat Sd and the passenger seat Sn, and is provided with a cushion 2 that constrains movement of the occupant p toward a site where an impact is applied during a collision event. A portion of the inflator 3 is inserted into the cushion 2. The cushion 2 comprises a main chamber 2 a and a sub-chamber 2 b disposed on the base panel 4 b opposite the occupant side base panel 4 a of the main chamber 2 a that is seated by the occupant p seated in the driver seat Sd. Upon collision, when the occupant p seated in the driver's seat Sd moves toward the passenger seat side, the expanded sub-chamber 2 b interferes with the side support SS on the driver side of the passenger seat Sn, and the expanded main chamber 2 a is provided with the reaction force from the passenger seat Sn.

A restraint performance improvement portion of a curtain airbag device for a vehicle is provided at a location of a lower end portion of a curtain airbag which location corresponds with a vehicle seat when the vehicle seat is in a comfortable state. The restraint performance improvement portion inhibits a head area of a vehicle occupant from slipping past the curtain airbag to a vehicle width direction outer side thereof when the vehicle occupant is being restrained.

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.
