The airbag device is characterized by a state in which the cover member is bent along the soft portion, covering at least a portion of the outer periphery of the airbag cushion in stowed form.

Airbag device

A side airbag device comprising a bag-like cushion that is provided to a side section of a seat back of a vehicle seat and inflates and expands toward the side of a passenger in the vehicle seat using a gas. The cushion includes: a first part having four sides and including a first chamber; a second part that has four sides, is adjacent to the first part, and includes a second chamber; and a third part that has four sides, is adjacent to the first part and the second part. When inflated and expanded, the cushion is a triangular column that is a columnar shape having a space open on both the top and bottom and surrounded by the first part in which the first chamber is inflated and expanded, the second part in which the second chamber is inflated and expanded, and the non-inflated third part.

A side airbag device stowed in a side part of a vehicle seat and includes: an airbag for restraining an occupant by expanding and deploying; and an inflator provided in a side wall part of a seat frame in the vehicle width direction extending in the vehicle traveling direction when a horizontal cross section of the vehicle seat is viewed from above, and that supplies expansion gas to the airbag. The airbag includes a main chamber that expands and deploys towards the front and a pre-push chamber that expands and deploys before the main chamber to the inside of the main chamber in the vehicle width direction. Furthermore, the pre-push chamber has a structure with an extension portion extending from the inflator towards the rear of the vehicle seat.

Side airbag device and method for manufacturing the same

The present invention is a side airbag device stowed in a side support part of a vehicle seat, which includes: an airbag capable of expanding and deploying toward a front side from the side support part; an inflator that supplies expansion gas to the airbag; and a bracket that retains the airbag in a compressed state. The inflator is secured to an inner side (occupant side) of a side frame of the vehicle seat. Furthermore, the bracket has a rear region that covers a rear side of the airbag in a compressed state and an inner region that extends continuously forward from the rear region between an inner side of the airbag and a seat pad.

The present invention is provided with an inflator arranged on the occupant side of the side frame positioned on the side portion inside the seatback that generates expansion gas and an airbag that is expanded by the expansion gas and protects an occupant seated on the vehicle seat. The airbag includes a main chamber that deploys toward the front of the seatback, and a pre-chamber that houses the inflator inside and is connected to the occupant side of the main chamber. In addition, an internal tether having a front end part connected to the front portion of the pre-chamber and a rear end part connected to the rear portion of the pre-chamber are provided inside the pre-chamber.

To prevent outward gas leakage between the airbag cushion and inflator during expansion and deployment with a simple configuration. The present invention provides an airbag device including: an airbag cushion having at least two panels; an inflator that discharges gas inside the airbag cushion; a first piece extending from an edge of a first panel of the two panels that is folded in the middle into the airbag cushion; a second piece provided on a portion near the edge of a second panel facing the first piece inside the airbag cushion and sewn to the folded part of the folded first piece; and an insertion passage for the inflator formed from sewing the folded part and the second piece, and extending from inside the airbag cushion to outside.

Airbag device and method for manufacturing airbag device

The side airbag device is provided with a cushion, an inflator arranged on the occupant side of a side part of a seat frame, and a support plate, where the cushion in a folded state includes: a first portion positioned on the occupant side of the seat frame side part, and a second portion positioned on the side opposite the occupant side of the seat frame side part and wraps around the vehicle front side from the first portion to sandwich the seat frame side part together with the first portion; and the support plate includes: a main body part for supporting the second portion, and a rearward extending part, in which through-holes and are formed extending from the main body part toward the rear of the vehicle beyond the second portion for allowing stud bolts and of the inflator to pass through.

A side airbag device having an airbag cushion that restrains an occupant by expanding and deploying and an inflator disposed on an inner side of the seat frame that supplies expansion gas to the airbag cushion; and a holding part that holds the airbag cushion. The airbag cushion includes an inner expanding portion internally containing the inflator and an outer expanding portion connected to the inner expanding portion and is disposed on an outer side of the seat frame by being folded back at a front edge portion of the seat frame. The outer expanding portion includes a folded portion of the airbag cushion. A forward portion of the holding part contacts an outer surface of the folded portion of the outer expanding portion, and a rearward portion is connected to the seat frame. Furthermore, the holding part is configured to cover a part of the outer expanding portion.

The present invention is a side airbag device stowed in a seatback of a vehicle seat, comprising: an inflator arranged on the occupant side of a side frame which is positioned on a side part inside the seatback, that generates expansion gas, and an airbag which expands due to said expansion gas and protects the occupant seated in the vehicle seat. The airbag includes a main chamber that deploys toward the front of the seatback, and a pre-chamber that houses the inflator inside and is connected to the occupant side of the main chamber.
