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 airbag assembly includes a housing and a side airbag inflatable to an inflated position. The side airbag in the inflated position has an upper lobe and a lower lobe supporting the upper lobe on the housing. The side airbag includes an internal panel between the upper lobe and the lower lobe. A tether has a first end anchored to the housing and a second end anchored to the upper lobe.

An airbag device includes an airbag, a connecting member extending from the airbag, and an actuator mounted on an airbag housing for controlling an inflation manner of the airbag. The actuator includes an actuator body that includes an operating pin which penetrates the connecting member, a mounting plate that holds the actuator body and is secured to the airbag housing, and a supporting plate that is disposed in a vicinity of a leading end portion of the operating pin. The supporting plate includes a supporting hole for receiving the operating pin, and a flange that is formed in a part of a periphery of the supporting hole toward which the connecting member is released. The flange extends along an axial direction of the operating pin towards the leading end of the operating pin for supporting the leading end portion of the operating pin with its surface facing the operating pin.

An airbag device may include: an airbag cushion part inflated by operating gas introduced thereto; a vent part formed through the airbag cushion part, and configured to discharge the operating gas within the airbag cushion part; a cord movement prevention part mounted on one side of the vent part; and one or more tether cord parts mounted on the other side of the vent part, and configured to tighten and close the vent part while passing through the cord movement prevention part, when the airbag cushion part is deployed.

A side airbag (SAB) of a vehicle includes: a main chamber disposed in a seat to be deployed from a side surface portion of the seat and, when deployed, configured to cover at least one of a thoracic region, an abdomen region, or a pelvis region of an occupant; a main inflator configured to supply gas to the main chamber to deploy the main chamber; and an auxiliary chamber communicating with the main chamber to allow the gas inside the main chamber to be supplied to an interior of the auxiliary chamber and connected to the main chamber to be deploy above the main chamber.

An airbag includes a bag body, an exhaust portion which has an exhaust hole, and a connecting member which is connected to the exhaust portion by the root portion inside the bag body. The bag body includes a main inflatable portion that includes a first and a second side walls which are opposed in a left and right direction at airbag deployment, and a protruding inflatable portion that protrudes partially rearward from a first end region in the left and right direction of an upper region of a rear portion of the main inflatable portion as deployed. The exhaust portion is formed in the first side wall of the main inflatable portion on a side the protruding inflatable portion is disposed, and is positioned farther downward than an apex of the protruding inflatable portion, as viewed from a side of the airbag as deployed.

An airbag device includes: an airbag having an exhaust hole capable of discharging a part of the inflation gas introduced therein upon opening; and an opening/closing control device capable of controlling opening/closing of the exhaust hole. The airbag has: a flexible bag main body; a discharge part having the exhaust hole; and a coupling member. Peripheral edges of a pair of peripheral wall constituting parts are joined to form the bag main body and the discharge part. Discharge part forming portions, which constitute the discharge part, partially protrude in the peripheral wall constituting parts, respectively. An opening, which constitutes the exhaust hole, is formed in a region, which is closer to a tip end-side of the discharge part than seal parts crimped to each other when the discharge part is pulled into the bag main body.

An airbag device includes an airbag cushion unit inflatable with working gas introduced thereto, one or more variable vent units protruding outward from the airbag cushion unit and including a hollow portion communicating with an inner portion of the airbag cushion unit, and one or more tether units having one portion shaped to surround the variable vent unit and the other portion fixed to an outer portion of the airbag cushion unit, and configured to tighten and close the variable vent unit in response to the airbag cushion unit being inflated.

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 airbag device includes an airbag formed with a discharge portion. The discharge portion includes: an opening portion; a tack portion around the opening portion; and a regulating belt portion disposed on a peripheral edge of the opening portion to regulate opening and closing of the opening portion. When the inflation of the airbag is completed, the tack portion is maintained in a folded state by the regulating belt portion due to tension acting on the regulation belt portion, so that a closed state of the opening portion is capable of being maintained, and when the tension does not act on the regulating belt portion, the folded state is released and the opening portion is brought into an open state.
