PASSENGER-SIDE AIRBAG
When the passenger-side airbag 1 is inflated fully, vertically-extending recesses 8, 9 are formed in left and right sides of an occupant-facing surface 2. A protrusion 10 between the recesses 8 and 9 restrains a head portion of an occupant, and the left and right protrusions 11, 12 restrains shoulders. In the case where a small occupant is restrained, the recesses 8, 9 remain.
1 . A passenger-side airbag comprising an occupant-facing surface facing an occupant in an inflated and deployed state,
wherein in the inflated and deployed state, the occupant-facing surface has a first recess, a second recess, and a first protrusion, the first and second recesses being respectively provided in left side and right side portions of the occupant-facing surface and extending in a vertical direction, the first protrusion being defined between the first and second recesses.
2 . The passenger-side airbag according to claim 1 , wherein the occupant-facing surface has a second protrusion located leftward of the first recess, and a third protrusion located rightward of the second recess, and the first protrusion is flush with or recedes forward relative to the second and third protrusions.
3 . The passenger-side airbag according to claim 1 , comprising a tether that pulls the occupant-facing surface forward to form each of the recesses.
4 . The passenger-side airbag according to claim 3 , wherein the tether comprises an upper tether and a lower tether, the upper tether being coupled to an upper portion of each of the recesses, the lower tether being coupled to a lower portion of each of the recesses.
5 . The passenger-side airbag according to claim 3 , comprising a panel that defines the occupant-facing surface,
wherein the panel includes a tuck, and a rear end of the tether is connected to the tuck.
6 . The passenger-side airbag according to claim 5 , wherein the tuck has a uniform fold-in width along the vertical direction.
7 . The passenger-side airbag according to claim 5 , at least a portion of the tuck in the vertical direction has a different fold-in width from another portion.
8 . The passenger-side airbag according to claim 5 ,
wherein the panel has an upper side that extends in a lateral direction along an upper portion of the occupant-facing surface,
wherein the upper side includes a cut provided in at least one of an area located leftward of the first recess and an area located rightward of the second recess, and wherein the cut has a left side edge and a right side edge that are sewn onto each other.
9 . The passenger-side airbag according to claim 1 , wherein the first recess and the second recess extend in parallel to each other.
10 . The passenger-side airbag according to claim 1 , wherein the first recess and the second recess have a spacing from each other that decreases toward a lower area.
11 . The passenger-side airbag according to claim 1 ,
wherein in the inflated and deployed state of the passenger-side airbag, the first recess and the second recess have a spacing of 150 to 350 mm from each other in a middle portion in the vertical direction of the occupant-facing surface, and
wherein in the middle portion, the first recess and the second recess have a depth of 100 to 200 mm.
12 . The passenger-side airbag according to claim 3 , wherein the tether includes a perforated slit, and once inflation is complete, the tether breaks along the slit and increases in length.
13 . The passenger-side airbag according to claim 1 , wherein the first protrusion comprises only a single protrusion defined between the first recess and the second recess.
