A safety airbag device, including a safety airbag having an inflated state and a stowed state, a gas generator, used to generate gas to inflate the safety airbag so that the safety airbag enters the inflated state; and a deflector, used to guide the gas generated by the gas generator before the gas generated by the gas generator enters the safety airbag. The deflector includes a first cavity and a second cavity. The first cavity includes a first gas inlet and a first gas outlet. The second cavity includes a second gas inlet and a second gas outlet. The first gas outlet and the second gas inlet are in fluid communication with each other.

In an assembly (20) of an elongate inflator (10) which has an outer housing (14) with outflow openings (18) spread along the circumference (U) and defining an outflow area (16) and an outflow direction, and of a clamp-type diffusor (22) enclosing the outflow area (16), the diffusor (22) includes a central receiving opening (24) into which the outer housing (14) protrudes so that the diffusor (22) circumferentially encloses an axial portion of the outer housing (14) which comprises the outflow area (16). At the inner side of the diffusor (22) delimiting the receiving opening (24) at least one bearing surface (34) and at least one gas guiding surface (30) are provided, wherein the bearing surface (34) bears directly against the outer housing (14) of the inflator (10) and the gas guiding surface (30) is radially spaced apart from the outer housing (14) while forming at least one collecting chamber (30) into which gas flowing out of the outflow area (16) is flowing. The collecting chamber (32) opens into at least one outlet opening (36) through which gas exits the diffusor (22) in an outlet direction (R.sub.D) transversely to the outflow direction out of the inflator (10).

An airbag apparatus for a vehicle my include an airbag housing accommodating an airbag cushion, an inflator supplying gas into the airbag cushion, a hard retainer fixing the inflator to the airbag housing, and a soft retainer having a first side coupled to the hard retainer and controlling a flow of the gas supplied from the inflator.

A curtain airbag device capable of preventing a cushion from damaging a front pillar trim or being caught by the front pillar trim upon deployed. A cushion 102 of a curtain airbag device 100 is inflated and deployed at a side wall of a vehicle interior to restrain an occupant. The curtain airbag device 100 includes: a cushion 102 having a bag shape and inflated and deployed on the vehicle front side of a passenger seat; and a first strap 148. The first strap 148 has one end 156 attached to a front pillar 104 and the other end 162 attached on the vehicle inner side of the cushion 102 in an elongate stored form. The first strap 148 moves to the vehicle inner side and is strained by inflation and deployment of the cushion 102 pushing out a front pillar trim 184 that covers the front pillar 104 to the vehicle inner side.

A throat and fill tube protection device for an inflatable airbag includes a first portion, a second portion and an overlapping region. The first portion is a generally Y-shaped portion with a first arm and a second arm connected at a base. The first arm defines an inlet for receiving an inflator. The second arm defines a first channel for directing a first portion of the inflation gases in a first direction. The second portion defines a second channel for directing a second portion of the inflation gases in a second direction. The second direction is generally opposite the first direction. The overlapping region is cooperatively defined by first and second overlapping areas of the first and second portions, respectively.

The invention relates to a combustion chamber (10) comprising an opening device for a compressed gas tank (21) of a hybrid inflator (20), wherein the combustion chamber (30) comprises a sleeve-type combustion chamber sidewall (34) confining a combustion chamber interior (31) and a combustion chamber bottom (10), wherein the opening device is arranged on a surface (11) of the combustion chamber bottom (10) facing away from the combustion chamber interior (31) and faces away from the combustion chamber interior (31). In accordance with the invention, the combustion chamber bottom (10) is tightly connected to the combustion chamber sidewall (34) so that in the case of operation the combustion chamber bottom (10) is bendable.

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 front air bag for a vehicle is provided. The air bag includes an air bag cushion that has of a plurality of chambers and a gas flow passage that supplies each of the chambers with gas of an inflator. A variable valve selectively closes or opens the gas flow passage. Additionally, a controller determines a type of vehicle collision and operates the variable valve based on the collision type.

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.
