Abstract: A gas generator is provided, the gas generator having a propellant cushion that prevents movement of propellant wafers, tablets, or grains by providing a bias thereagainst. Furthermore, the cushion may be formed from a polyurethane-based foam material and if desired, a known oxidizer combined within the foam. Channels inherent within the polyurethane-based foam enhance the combustion of the main gas generant. Alternatively, the substituted polyurethane polymer combined with an oxidizer may be formed as a monolithic grain that provides autoignition and gas generant function in lieu of a primary gas generant or in lieu of an igniter composition, for example.

Abstract: A gas generating system includes a housing and a nozzle coupled to the housing. The nozzle includes at least one bi-directional gas exit passage configured to provide a thrust-neutral release of gases from the nozzle.

Abstract: A gas generating system includes a housing, a quantity of gas generant material positioned within the housing, and a quantity of booster material positioned in the housing spaced apart from the gas generant. A movable first screen is positioned in the housing such that the booster material is on a first side of the screen and the gas generant material is on a second side of the screen opposite the first side of the screen. The screen is structured to enable fluid communication between the first and second sides of the screen.

Abstract: An inflatable device includes a protective patch attached to an interior surface of the device to cover a portion of the surface, wherein the patch is not positioned over an opening in the device.

Abstract: A gas generating system includes a housing and a gas generant combustion chamber within the housing. A liquid coolant chamber is provided within the housing. A mixing chamber is positioned within the housing so as to enable fluid communication with the combustion chamber and the coolant chamber after activation of the gas generating system. A movable member is positioned within the housing in operative communication with the coolant chamber, such that movement of the movable member forces coolant from the coolant chamber directly into the mixing chamber.

Abstract: A gas generating system is presented that contains a gas deflector positioned about an associated gas generator. The deflector may be attached to an outer wall of a perforate housing of the gas generator, or, alternatively, the deflector may be attached to a support structure positioned about the perforate housing, whereby gases exiting the gas generator upon actuation thereof, impinge upon the deflector.

Abstract: A gas generating system includes a housing defining an interior, a housing partition dividing the interior into a first portion and a second portion, and at least one opening to enable fluid communication between the second portion and an exterior of the second portion after activation of the gas generating system. The partition is movable within the interior such that a movement of the partition in a first direction causes a flowable material positioned within the second portion to flow through the at least one opening.

Abstract: An initiator housing assembly includes a preformed initiator receiving portion defining a first cavity and a body portion affixed to the receiving portion and defining a second cavity. An opening leading into the first cavity is positioned within the second cavity. An initiator assembly, as gas generating system, and a vehicle occupant protection system incorporating the initiator housing assembly are also provided.
