Patent ID: 7469922

Claim:
A head-protecting airbag apparatus mountable on a vehicle having three rows of seats and windows, a third-row seat of the vehicle being so folded as to stand proximate to an interior side of the windows, the apparatus comprising an airbag secured at an upper edge thereof to a vehicle body along an upper edge of windows, while being folded and housed in the upper edge of the windows, the airbag, when fed with inflation gas by an inflator, protruding downwardly from a housing and deploying to cover the interior side of the windows, the airbag comprising a gas admissive portion admitting inflation gas inside thereof, and a non-admissive portion admitting no inflation gas, the gas admissive portion comprising a first, second, and third shielding portions each adapted to cover the interior side of each window at a complete inflation of the airbag; mounting portions located at an upper edge of the airbag for securing the airbag to a body of the vehicle along an upper edge of the windows, wherein the airbag is secured at the mounting portions to the vehicle body along the upper edge of the windows; and a dividing recess extending upwardly from a lower edge of the airbag, in an area of the non-admissive portion between the third shielding portion adapted to cover the interior side of a window located at the side of the third-row seat and the second shielding portion adapted to cover the interior side of a window located at the side of a second-row seat, wherein: the dividing recess, in the event that the third shielding portion engages the folded third-row seat during the course of airbag deployment, separates a lower edge of a region between the second shielding portion and the third shielding portion, so that the second shielding portion is not hindered from smooth development; the non-admissive portion includes a first panel portion located between the first shielding portion and the second shielding portion and a second panel portion located between the second shielding portion and the third shielding portion; the dividing recess is arranged at the second panel portion; the mounting portions are arranged in an upper area of the third shielding portion; the second shielding portion comprises more than one vertical chambers disposed one behind another, each of the vertical chambers extending along the vertical direction; each of the vertical chambers reduces a dimension thereof in the longitudinal direction of vehicle when inflated; when the airbag is completely inflated, the dividing recess is located rearward of a straight line connecting a rear end and lower end region of the second shielding portion and one of the mounting portions located at an immediate rear of the second shielding portion, in such a manner as not to interrupt the straight line; and the one of the mounting portions is rearward of an upper end of the dividing recess.
