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.

The invention relates to an airbag module (16) of a vehicle safety system as well as to a method of mounting an actuator assembly (10) for activating a tensile means (12) on a module casing (14) of the airbag module (16), comprising the following steps: a) the tensile means (12) is connected to the actuator assembly (10) and is fixed to a mounting element (18) together with the actuator assembly (10) so that the tensile means (12), the actuator assembly (10) and the mounting element (18) constitute a pre-mounted unit (20); the pre-mounted (20) is arranged inside the module casing (14) and is fastened to the module casing (14) by means of the mounting element (18).

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 of the disclosure includes an airbag module that is installed in a central region of a steering wheel of a vehicle, and that accommodates an airbag that can deploy behind the steering wheel when a driver is seated in the driver's seat. The airbag module has an airbag inflation control unit that controls an inflation direction of the airbag in such a manner as to allow the airbag to inflate above the airbag module, after the airbag has inflated in such a direction as to abut on the driver's chest at the time of deployment of the airbag.

A positional-dependent airbag deployment system is provided. A plurality of tether cutters are configured to cut at least one of a plurality of tethers affixed to an airbag. An image sensor is configured to monitor the position of an occupant's head within a vehicle. In response to detecting a collision event, an airbag controller determines a trajectory of the occupant's head based on the image sensor data and other data and determines a cutting sequence of the tethers such the airbag will be deployed in a trajectory to intercept the occupant's head.

An assembly including a vehicle seat. The assembly includes an airbag supported by the vehicle seat and inflatable to an inflated position. The airbag includes a main chamber elongated along an axis and an extension supported by the main chamber. The extension extends from the main chamber transverse to the axis in the inflated position. The main chamber includes a lower segment and an upper segment selectively extendable away from the lower segment along the axis from an unreleased position to a released position. The extension is supported by the upper segment of the main chamber and the extension is translatable along the axis with the main chamber from the unreleased position to the released position.

Embodiments of the present disclosure relate to a vehicle seat airbag apparatus, wherein: when a side collision accident occurs, an active vent hole is closed to delay the deployment speed of a front cushion and thus to enable a side cushion so as to have sufficient internal pressure, thereby improving ability to respond to a side collision; and when a frontal collision accident occurs, the active vent hole maintains an open state to rapidly deploy the front cushion, thereby improving ability to respond to a frontal collision.

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.

An apparatus for helping to protect an occupant of a vehicle includes an airbag configured to be mounted to a seat back of a vehicle seat. The airbag is inflatable between the seat back and an adjacent side structure of the vehicle to one of a first deployed condition in which the airbag is configured for a non-reclined condition of the vehicle seat, and a second deployed condition in which the airbag is configured for a reclined condition of the vehicle seat. The airbag is configured to deploy to the first deployed condition in response to determining a non-reclined condition of the vehicle seat and to the second deployed condition in response to determining a reclined condition of the vehicle seat.
