A side airbag device capable of restricting an occupant from moving to the inner side in the vehicle width direction while restraining the head of the occupant is inflatable and deployable in a space beside an occupant seated in a vehicle seat. The side airbag device includes an inflator configured to generate a gas and a bag-shaped airbag inflatable and deployable in response to the gas upon activation of the inflator to protect a lateral portion of the occupant. The airbag includes a torso protection portion, and a head protection portion configured to be provided above the torso protection portion and inflatable and deployable between an upper portion of a shoulder of the occupant and a lateral portion of a head of the occupant. The head protection portion is bendable at an acute angle relative to the torso protection portion in an inflated and deployed state of the airbag.

Side airbag device

An airbag device including: a folded airbag; an attachment member configured to house the folded airbag and to be fixed to the vehicle; and an airbag lid including a main body portion and a protruding support portion. The main body portion is connected to the attachment member in a state of covering the folded airbag from a side opposite to the attachment member. The protruding support portion protrudes from the main body portion. At least a part of the protruding support portion is covered by the trim. The protruding support portion includes: a base end side edge portion joined to the main body portion; a tip end side edge portion provided on a side opposite to the base end side edge portion; a locking portion attaching to the trim; and a reinforcing portion provided continuously along the tip end side edge portion.

Airbag device

A side airbag device includes an inflator; and a bag-shaped airbag inflatable and deployable in response to a gas upon activation of the inflator. The airbag includes a torso protection portion inflatable and deployable in a space beside a torso of the occupant, a support portion provided on a console box side of the torso protection portion and configured to be pushed onto a top surface of the console box in an inflated and deployed state, and a hip protection portion inflatable and deployable between a hip of the occupant and a lateral portion of the console box. The support portion and the hip protection portion are defined by a continuous chamber. The inflator is positioned from above to below the support portion in a side view of the vehicle. The airbag is mounted on a lateral portion of the vehicle seat via the inflator.

A side airbag device includes an airbag including a first inflation portion fixed to a seat and a second inflation portion inclining toward an occupant with respect to the first inflation portion. The airbag includes an occupant side panel disposed on an occupant side, a non-occupant side panel disposed opposite the occupant side panel, and a strip connection panel connecting a peripheral edge of the occupant side panel and a peripheral edge of the non-occupant side panel. The non-occupant side panel is spaced from the occupant side panel in a vehicle width direction. The connection panel includes a bend portion between a first peripheral edge portion connected to a first part of the peripheral edge of the occupant side panel defining the first inflation portion and a second peripheral edge portion connected to a second part of the peripheral edge of the occupant side panel defining the second inflation portion, or in the second peripheral edge portion.

A side airbag device includes an inflator and an airbag. The airbag includes a deployable bag and a separator that separates the bag into a first chamber and a second chamber. The first chamber includes a support inflation portion and a protection inflation portion. The support inflation portion is deployable in such a shape that it gradually broadens from its lower end portion toward its upper end portion along a seat-side portion. The protection inflation portion is deployable at one end side of the support inflation portion. The inflator is disposed to supply a gas into the support inflation portion. The separator includes at least one gas distribution hole in a portion thereof that separates the support inflation portion of the first chamber and the second chamber from each other. The second chamber is provided below the first chamber.

A side airbag device () protects the passenger () in the lateral space (). The airbag () has an attaching portion () attached to a side section () of a seat (), and is folded so as to be able to deploy from the side section () toward the lateral space (). The inflator () generates gas and thereby deploys the airbag () to a leading end portion () in the deployment direction (F). The airbag () has a bellows-like folded section in which a part () between the leading end portion () and the attaching portion () is folded in a bellows-like shape. The bellows-like folded section is disposed in front of the attaching portion () in the deployment direction (F), and is folded double toward the back of the deployment direction (F) so that a portion () close to the attaching portion () is positioned therein.
