Provided is an airbag which further reduces the degree of injury to a vehicle occupant while also exhibiting sufficient occupant protection performance using less output from the inflator, by both preventing airbag internal pressure from rising excessively when making contact with the occupant and increasing the speed of deployment in an occupant-protection area. This hollow-weave airbag has an opening in a main chamber that inflates for the purpose of occupant protection, a structure wherein a first yarn extending separatingly from a first fabric layer of the opening to a non-inflating portion is caught on a float yarn extending on the inside of a second fabric layer and subsequently caught on a float yarn extending on the inside of the first fabric layer, this structure being repeated at least once and forming a pair with another structure wherein a second yarn extending separatingly from the second fabric layer of the opening to the non-inflating portion is caught on the float yarn extending on the inside of the first fabric layer and subsequently caught on the float yarn extending on the inside of the second fabric layer, this structure being repeated at least once.

There is provided an airbag in which there are fewer restrictions in a place for setting a tension member and a place for setting a vent hole. Airbag (10) of the present invention has bag-shaped airbag main body (20), tension member (30, 30a, 30b) disposed inside airbag main body (20), and vent hole (50) provided in airbag main body (20). In two-dimensional view in which an inner side of inflated and deployed airbag main body (20) is viewed from a direction orthogonal to vent hole (50) via vent hole (50), tension member (30, 30a, 30b) has wrap portion (35) disposed at a position overlapping vent hole (50), and a dimension of at least a part of wrap portion (35) in an orthogonal direction is smaller than a gap of a portion of vent hole (50), which corresponds to wrap portion (35), in the orthogonal direction.

A passenger seat airbag device includes an airbag including a front collision restraining surface, and an oblique collision restraining portion including a protruding portion in which a surface is set as an oblique collision restraining surface, and a restraining recess portion whose facing surfaces are able to restrain the head of the occupant. The rear wall main portion has the front collision restraining surface. The rear wall end edge portion has the oblique collision restraining surface. The upper edge of the rear wall end edge portion is coupled to a rear edge of the upper wall portion. The lower edge of the rear wall end edge portion is coupled to a rear edge of the lower wall portion. An entire edge of the separation edge of the rear wall end edge portion is coupled to a rear edge of the rear edge side portion.

An assembly includes an airbag having an inflation chamber. The inflation chamber is defined by a first inflatable section, a second inflatable section, and a duct fluidly connecting the first inflatable section and the second inflatable section. A tether is external to the inflation chamber. The tether has a cinching loop encircling the duct. The tether has a tail extending from the cinching loop and the tail is fixed to the airbag.

An apparatus for helping to protect an occupant of a vehicle includes an airbag comprising a vent having a closed condition blocking inflation fluid flow through the vent, and an opened condition permitting inflation fluid to flow through the vent. The vent includes a vent opening formed in a panel of the airbag and a vent flap connected to the airbag panel adjacent to the vent opening. The vent flap is configured to block inflation fluid flow through the vent opening in the closed condition of the vent, and to permit inflation fluid flow through the vent opening in the opened condition of the vent. The vent flap includes a plurality of folds configured to form one or more pleats in the vent flap. The vent flap is held extending across and covering the vent opening in the closed condition of the vent. The vent flap is released and uncovers the vent opening in the open condition of the vent. In response to the vent flap being released in the open condition of the vent, the pleats are configured to unfold under the pressure of inflation fluid in the airbag to uncover the vent opening and permit inflation fluid to vent through the vent opening.

An airbag for a vehicle is proposed. The airbag includes an inflator configured to generate gas, the airbag cushion connected to the inflator and configured to expand by the gas, and a variable vent provided in a first side of the airbag cushion and configured to control opening and closing state of a vent hole of the variable vent for gas escape from the airbag cushion in response to an operational condition of the airbag cushion.

An airbag module (10) for a restraint device (14) includes an airbag (24), in particular a seat-integrated side airbag, and a slidable actuator (40), wherein the airbag (24) has at least a first chamber (26) and at least a second chamber (28) which are fluidically connected to each other via a fluid communication, wherein the actuator (40) has a blocking position in which the fluid communication is blocked and a release position in which the fluid communication is released.

An occupant protection device includes: an airbag including an upper inflating portion and a lower inflating portion, and a rear inflating portion having a restraint surface that receives the occupant, the airbag being provided with a hollow portion penetrating in a left-right direction in a center; and a protrusion length adjustment unit configured to adjust a protrusion length from the accommodation position to the restraint surface in the airbag. An exhaust port configured to exhaust the inflation gas is disposed on an inner peripheral surface side in the vicinity of an intersection portion between the upper inflation portion and the lower inflation portion of the airbag. When the protrusion length by the protrusion length adjustment unit is adjusted to be long, the upper inflation portion and the lower inflation portion approach each other, so that an edge member approaches the exhaust port, thereby reducing an exhaust amount.

An airbag includes: a bag main body: and regulating units configured to regulate an expansion completed shape of the bag main body. The bag main body has an expansion completed shape as a substantially square cylindrical shape, where a hollow portion which penetrates substantially along a left-right direction is provided and a circumference of the hollow portion is surrounded by an upper expansion portion and a lower expansion portion and a front expansion portion and a rear expansion portion. The regulating units are arranged at a plurality of horizontally symmetrical locations centered on a center of the bag main body on the left-right directional side and each of the regulating units is configured to straddle the hollow portion when viewed from a lateral side in the left-right direction and at least an upper edge side and a lower edge side are connected to the bag main body side.

The invention relates to an airbag module (10) for a vehicle occupant restraint system (12), comprising an airbag (14), an inflator (18), a shaping tether (22) for influencing the airbag deployment geometry which is connected to the airbag (14) at one tether end, and comprising a port release tether (20) which is connected to a discharge port closure (26) of the airbag (14) at one tether end, wherein the port release tether (20) is connected to the discharge port closure (26) so that it releases a discharge port (28) of the airbag (14) from a predetermined tensile tether force, and wherein an activatable tether release device (24) coupled both to the shaping tether (22) and to the port release tether (20) is provided for actively releasing the tethers (20, 22). Furthermore, the invention relates to a method of operating a vehicle occupant restraint system (12) comprising said airbag module (10), wherein airbag deployment takes place in response to predetermined basic conditions, such as in response to the weight of a vehicle occupant (16) and/or of a driving mode for manual or automated and, resp., autonomous driving.
