摘要： 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.

摘要： A vehicle side airbag device including an inflator, a side airbag, and a duct is installed at a side section on a vehicle width direction outer side of a seatback of a vehicle seat configured to restrain an occupant using a three-point seatbelt. The side airbag receives a supply of gas from the inflator in a vehicle side-on collision. As a result, a waist chamber is inflated and deployed from a lower portion of the side section toward a side of a waist of the occupant, and a head chamber is inflated and deployed from an upper face side of the side section toward a side of a head of the occupant. The duct extends along a vertical direction of the side airbag inside the side airbag, and is configured to guide gas from the inflator into the waist chamber and into the head chamber.

摘要： 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.
