An airbag module according to various implementations includes an inflatable cushion, a folding tab, and an inflator. The inflatable cushion includes a first panel and a second panel, each of the first and second panels including an inner surface and an outer surface. When the outer surfaces of the first and second panels are coupled together to form an inverted seam, the folding tab is coupled between the respective outer surfaces of the first and second panels. As a result, the inflatable cushion includes an increased strength while maintaining an ease of assembly using current inflatable cushion folding machines.

The present disclosure provides a vehicle airbag device including: an airbag that inflates and deploys due to supply of gas, that has a main body and a projection that projects in a vehicle rearward direction, and that has a gap portion, between the main body and the projection, which opens in the vehicle rearward direction; and a coupling portion that couples together a first attachment portion set at the airbag at a front end portion side of the gap portion and a second attachment portion set at a side portion of the projection, and which, when inflation and deployment of the airbag, stretches between the first attachment portion and the second attachment portion, which is positioned further in the vehicle rearward direction than the first attachment portion.

The airbag device includes an airbag including a base fabric and an occupant protection fabric whose outer peripheries are joined together. The occupant protection fabric is positioned on the vehicle rear side of the base fabric and configured to restrain an occupant, and includes: at least one protruding portion that protrudes to the vehicle rear side; a flat portion that is continuously formed from the at least one protruding portion and is designed to come into contact with the occupant; and a tether that is disposed between the base fabric and the at least one protruding portion in the airbag, extending from the flat portion to the joint between the occupant protection fabric and the base fabric. The tether is joined at its end on the joint side with a base edge of the at least one protruding portion and the outer periphery of the base fabric.

A curtain airbag attached to a vehicle body and expanded and deployed by a gas from an inflator containing: a first region along a lower edge; a second region adjacent above the first region with a first fold line; a third region adjacent above the second region with a second fold line formed on an opposite side of the first fold line across the second region. The first region is in a condition folded back at the first fold line to face a first surface side of the second region, the second region is in a condition folded back at the second fold line such that the folded back first region is between the second region and the third region, the third region is in a condition rolled upward on a second surface side. Rolling starts from the second fold line.

A rear vehicle seat airbag module configured to be mounted to a portion of a seat back of a front vehicle seat comprising an inflator and an inflatable cushion comprising a lower portion, an upper portion and an external tether connecting the lower portion and the upper portion. The inflator provides inflation gas to the inflatable cushion and the inflatable cushion is configured to deploy forward of an occupant seated in a rear seat of a vehicle by curving away from the occupant. The external tether is configured to control a trajectory of the deployment of the inflatable cushion by pulling the upper portion toward the lower portion to curve the inflatable cushion such that the upper portion is located above the lower portion.

A passenger protecting device including: an airbag device including an airbag that receives a supply of gas from an inflator and is inflated and expanded, by a front expanding portion that includes a front inflating portion to be inflated and expanded at a seat front side of the head portion and at least one of a chest portion and shoulder portions of the passenger, and a pair of left and right lateral expanding portions that include lateral inflating portions that are connected to the front expanding portion and are inflated and expanded at sides of the head portion of the passenger; and a position changing device that changes an inflated and expanded position of the airbag in a seat transverse direction, in accordance with a direction of collision of a collision body with respect to the vehicle seat.

A vehicle occupant protection device includes: an airbag structured as a single bag that is configured to cover a head area of a vehicle occupant, the airbag being stowed at a headrest or seatback of a vehicle seat, the airbag receiving a gas supply and inflating and expanding toward a seat front side, and the airbag including a front inflation portion that is configured to be inflated at the seat front relative to the head area and a left and right pair of side inflation portions that are connected to the front inflation portion and configured to be inflated at seat sides relative to the head area; and an opening portion that is provided at the airbag, is configured to cover the head area from the seat front side or a seat side, and is openable after the inflation and expansion of the airbag.

An airbag includes a main bag section and a center bag section deployable to protrude towards a vehicle interior out of an inboard side of the main bag section. An inboard-side member, which forms the inboard side of the main bag section, is composed of a front component and a rear component. The center bag section includes a front wall and a rear wall. The front wall is composed of a rear extended region of the front component which is disposed in such a manner as to protrude rearward out of the rear edge of the front component. The rear wall is composed of a front extended region of the rear component which protrudes forward out of the front edge of the rear component and has a generally identical outer contour to the rear extended region. The center bag section is formed by jointing outer edges of the front and rear extended regions.

A head-protecting airbag device includes: an airbag body; and a connecting piece which is formed of a sheet material with flexibility, wherein: the airbag body and the connecting piece constitute an airbag having a bag shape inflatable to cover an inboard side of a window of a vehicle; the airbag body includes an inboard side wall disposed on the inboard side at the time of inflation completion, an outboard side wall disposed on an outboard side, and a coupling target portion coupling the connecting piece; the coupling target portion is configured to be divided into an inboard side portion and an outboard side portion; and the root end of the connecting piece is nipped between the inboard side portion and the outboard side portion, and is coupled with the inboard side portion and the outboard side portion so as to be connected with the airbag body.

In a method for folding a side airbag a first material layer and a second material layer are connected along a first edge portion by a first seam and connected along second edge portions by a second seam perpendicular to the first seam to bound a chamber. The two material layers are placed flat upon one another and a region of the second seam is slipped in a first direction inwards while forming a tip. A tip-distal end of the first and second material layers is folded several times in the first direction and the tip is folded, with the folded-over portion being slipped in the first direction inwardly. A gas generator is inserted in the first direction into the two material layers; and roll folding is carried out from an end in opposition to the gas generator in a second direction in transverse relation to the first direction.
