An overhead airbag system includes a first airbag assembly with a first inflator and a first airbag cushion. The first airbag cushion includes an occupant-facing portion, a first side portion and a second side portion. The occupant-facing portion is connected between the first side portion and the second side portion and separates the first side portion from the second side portion by a first gap. The first airbag cushion is operable in an uninflated state and an inflated state. The airbag system also includes a second airbag assembly with a second inflator and a second airbag cushion. The second airbag cushion includes an occupant-facing wall and at least one side wall. The occupant-facing wall faces away from the occupant-facing portion of the first airbag cushion and the at least one side wall is positioned between the first side portion and the second side portion of the first airbag cushion.

A curtain airbag for a vehicle may include: a main chamber installed between a headliner and a vehicle body and provided to be downwardly unfolded to the interior of the vehicle; a diffuser being provided at an inlet portion of the main chamber connected with an inflator, formed with a first outlet and a second outlet which receive and discharge gas from the inflator; and an additional chamber connected with the second outlet of the diffuser and communicated with the second outlet to receive gas from the diffuser and inflated between the headliner and the vehicle body to separate the headliner from the vehicle body. In particular, the diffuser includes a joined portion to close partially or fully the first outlet, and the diffuser increases the gas supply to the main chamber when the joined portion is opened by an internal pressure of the diffuser.

The invention relates to a gas generator (10), particularly a pyrotechnical tube gas generator, with an axial longitudinal direction (L), comprising an ignition unit (20), a combustion chamber (30) axially mounted downstream from the ignition unit (20) and comprising a combustion chamber bottom (35) forming a combustion chamber outlet (36), and a filter chamber (70) that is axially mounted downstream of the combustion chamber (30). According to the invention, at least one guiding sleeve (50) and a front-side baffle plate (80) are formed in the filter chamber, a first end (51) of the guiding sleeve (50), on the side of the combustion chamber, being axially mounted downstream from the combustion chamber bottom (35), and a second end (53) of the guiding sleeve (50) being associated with the baffle plate (80), a first deflection section being formed on the baffle plate (80) and the guiding sleeve (50) which allows a gas flow to an outer side of the guiding sleeve (50) into an annular first discharge chamber (75).

A deployable containment system of a vehicle includes a pair of guide channels that surround an opening facing one of a forward direction of travel of the vehicle and a backward direction of travel of the vehicle. Each of the guide channels has a first end and a second end. A housing is mounted to the first ends of the guide channels. A shield is configured to: deploy from the housing; travel along the guide channels toward the second ends of the guide channels; and cover at least a portion of the opening, An actuator is configured to, in response to being triggered, deploy the shield from the housing and move the shield along the guide channels toward the second ends of the guide channels.

Device for fixing a connection to an OPW airbag, with an expansion sleeve (2), with a plurality of expansion shells (4), and a mandrel (6) extending longitudinally through the expansion sleeve (2) having a stretching piece (8) arranged in the vicinity of the expansion shells (4), the outer diameter of which stretching piece is greater than the inner diameter of the expansion shells (4).

An occupant protection device for a vehicle includes a seat, a three-point seatbelt device, and a belt airbag device. An occupant to board the vehicle is to sit on the seat. The three-point seatbelt device includes a seatbelt extendable across a front of an upper body of the occupant sitting on the seat. The belt airbag device includes a belt airbag that is provided at a shoulder belt section, which is extendable from a shoulder to a waist of the occupant, of the seatbelt, and that is configured to be deployed when a collision occurs. The belt airbag includes a belt-direction deployment section extendable and deployable along the shoulder belt section, and an intersecting-direction deployment section extendable and deployable in a direction intersecting the shoulder belt section. The sections are configured to form a single bag by being coupled to each other below a head of the occupant sitting on the seat.
