Abstract: An air bag is unfolded on a planar surface and is inflated with air. The air bag is loosely sandwiched between the upper and lower blades that are arranged in a radial configuration. Movable blocks progress toward the center to fold the upper and lower panels of the air bag against the central part of the air bag. The resulting central folded part of the air bag has a wave-like configuration, and the upper and lower panels are separated from each other. The ear-like portions of the air bag are wound around the central folded part of the air bag that is folded in a wave-like configuration. Then, the central part of the air bag is pressed downward to complete the folding process. Gas can be supplied smoothly from the inlet port to the periphery when the air bag is reinflated. The method for folding the air bag is simple, and the air bag can be inflated quickly.

Abstract: The invention provides an air bag apparatus of a motor vehicle which can securely protect a passenger in a much close state by an inexpensive means. Since a rear end (a patch portion (19)) of a tether belt (20) is positioned at a vertical surface (A) passing through a rear end (21) of an instrument panel (1) or in a front side thereof, in an initial expanding state of an air bag (4), a rearward development of the air bag (4) is restricted just before a passenger (M) due to a tension of the tether belt (20) even in the case that the passenger (M) stands close to the instrument panel (1), whereby no excessive impact is applied to the passenger (M).

Abstract: A steering wheel includes a boss, a spoke, and an air bag apparatus with a bag and a synthetic resin cover. When the vehicle is subjected to a collision, the bag is inflated and rupture opens a front wall of the cover. The front wall has two side rupture lines, a dividing rupture line between the side rupture lines, a center rupture line from the dividing rupture line, and two upper hinges between the side rupture lines and the center rupture line. When the cover ruptures open, the rupture lines rupture, causing each lid to bend and swing about the upper hinges. The dividing rupture line is disposed at a position so that the upper lids do not interfere with the rim.

Abstract: The invention provides an air bag apparatus of a vehicle which can securely protect a passenger (including a child) in a much closed state by an inexpensive means. Since a rear end (a patch portion (19)) of a tether belt (20) is positioned between a vertical surface (A) passing through a rear end (21) of an instrument panel (1) and a vertical surface (B) passing through a center (S) of a head portion of the passenger, in an initial expanding state of an air bag (4), a rearward development of the air bag (4) is restricted just before a passenger (M) due to a tension of the tether belt (20) even in the case that the passenger (M) is much close to the instrument panel (1), whereby no excessive impact is applied to the passenger (M).

Abstract: An air bag body (1) is expanded by charging an air therein after being expanded in a flat surface shape. Next, by gently gripping the air bag body (1) by upper and lower blades (26, 25) radially arranged in a radial direction of the air bag body (1), a height in a radial direction of the air bag body (1) is linearly restricted along the upper and lower blades (26, 25). Next, a plurality of movable blocks (24) are forward moved toward a center of the air bag body (1), and upper and lower panels (12, 11) of the air bag body (1) are accumulated. At this time, the upper and lower panels (12, 11) of the air bag body (1) are folded in a state of being apart from each other so as to form a wave shape. Next, the air bag body (1) is rotated, a portion left in a tab shape is wound around a periphery, and a center protruding portion of the air bag body (1) is pressed from an upper side, whereby a front surface deploying portion (35) is formed.

Abstract: An airbag includes first and second base cloths and a middle base cloth arranged therebetween for defining first and second compartments in the airbag. Gas communicating ports are arranged in the vicinity of the outer periphery of the middle base cloth to ensure gas communication between the two compartments. Four ring-shaped fixing portions are arranged around a gas introduction port to connect the second and middle base cloths, one of which has an exhaust port formed inside.

Abstract: A casing is fixed to a steering wheel and has a first center line, an upper space, and a lower space. The first center line is positioned below a second center line of the steering wheel. An inflator is arranged in the casing and has a third center line. The inflator is for generating a gas. The third center line is positioned below the first center line and positioned at a boundary between the upper space and the lower space. An air bag has an upper portion accommodated in the upper space and a lower portion accommodated in the lower space. The upper portion is in an upper folding state. The lower portion is in a lower folding state. The upper folding state is looser than the lower folding state.

Abstract: An middle fabric portion (43) is disposed between a first fabric portion (41) and a second fabric portion (42) that constitute a pouch-shaped air bag (1). The middle fabric portion (43) divides the interior of the air bag (1) into a first compartment (45) and a second compartment (46). The two compartments (45,46) communicate by communicating openings (51) formed at locations near the outer edge of the middle fabric portion (43). A center communicating portion (53) at the center of the middle fabric portion (43) is fastened to a retainer (14). The first fabric portion (41) and the second fabric portion (42) communicate by a middle communicating portion (57) formed between the center communicating portion (53) and an outer edge portion (44). The communicating openings (51) are formed in the middle fabric portion (43), at locations near the outer edge of the middle fabric portion (43).

Abstract: A retainer (15) adapted to fix an air bag (14) to a base plate (11) includes an expanded portion (15b) for covering an inflator (12). An angled portion (15d) of the expanded portion (15b) is provided with radially arranged gas through holes (15f). The center portion of an upper fabric material (14a) of the air bag (14) is affixed to the center of a top plate portion (15e) of the expanded portion (15b) by means of a rivet (41), thereby limiting the distance by which the air bag (14) projects toward the occupant.
