摘要： The side airbag device includes an inflator and a side airbag that is stored in a folded state in a side portion of a seatback of a vehicle seat and is inflatable and deployable in a space between a vehicle sidewall and a side portion of an occupant. The side airbag includes an outer bag and an inner bag. The inner bag houses the inflator and is disposed at a rear portion of the outer bag along an extending direction of the seatback. The outer bag is provided with a vent hole configured to communicate with an outside. The inner bag is provided with a gas circulating hole configured to communicate with the outer bag. The gas circulating hole is disposed at a position to be blocked by the outer bag when the side airbag in an inflated and deployed state is pressed between the occupant and the vehicle sidewall.

摘要： A seatbelt airbag for a vehicle is provided. The airbag is inflated in a seatbelt to restrain an occupant to reduce an injury to the occupant caused by the seatbelt. Particularly, since the airbag is locally inflated at occupant's shoulder and hip which are susceptible to injury by the seatbelt, an inflation speed is controlled, an impact is minimized, and the occupant may be restrained in the seat more rapidly and stably.

摘要： A gas generator includes a housing, a partition member which divides a space in the housing into a combustion chamber where a gas generating agent is accommodated and a filter chamber where a filter is accommodated, and a sealed container which externally seals the gas generating agent. The filter has a hollow portion which reaches an axial end surface located on a side of the combustion chamber. The sealed container is made of a member relatively low in mechanical strength so as to burst or melt as a result of burning of the gas generating agent. The partition member is made of a member relatively high in mechanical strength such that only a portion opposed to the hollow portion bursts as a result of burning of the gas generating agent to provide a communication hole which allows communication between the combustion chamber and the filter chamber with each other.

摘要： A gas generator assembly for an airbag module of a motor vehicle, including a generator housing with a first housing part and a second housing part, a combustion space formed in the generator housing for accommodating a pyrotechnic charge from which a gas for inflating a gas bag of the airbag module can be generated by combustion. At least one outlet opening is provided in the generator housing through which gas generated in the combustion space can be released for inflating the gas bag. At least one filter unit is arranged in the generator housing for filtering the gas generated from the pyrotechnic charge. The assembly includes a guide element arranged in the generator housing, by means of which the generated gas is guided to the at least one outflow opening. The guide element is of tubular form and has at least one deformation area.
