Problems solved by technology

[0005] However, when the gas generating agent is supported in the above manner, since the supporting member is made of fibers, sufficient elastic force cannot be obtained.
Therefore, these support members are not suitable for preventing the movement of the gas generating agent

Embodiment Construction

[0034] figure 1 It is a cross-sectional view of the air bag gas generator of the present invention. This embodiment is mainly used as a gas generator having a casing with an outer diameter of about 70 mm. In this gas generator, an inner cylindrical member 16 partitions an outer casing 3 constituted by a diffusion shell 1 and a closing shell 2 into an igniter storage chamber 23 and a combustion chamber 28 for a gas generating agent. An ignition device that ignites and burns the gas generating agent 6 when triggered by an impact, that is, an ignition device including an igniter 4 and a transfer charge 5 in this embodiment, is housed in the ignition device storage chamber 23 . The combustion chamber 28 is provided with: a gas generating agent 6 ignited by an ignition device to generate combustion gas; a first cushion member 100 supporting the gas generating agent and preventing its movement; and a second cushion member 102 supporting a conduction fuel 5 .

Abstract

Cushion members, for an air bag gas generator, that have sufficient elasticity to secure gas generating agents and that can also be easily manufactured is provided. In the cushion members for prohibiting movement of a member, contained in the housing, the surface characteristic of upper or lower surface, of both surfaces are designed such that the cushion members are laid on top of another, they do not adhere to each other. The air bag gas generator using the cushion members is to be provided.

Description

technical field [0001] The present invention relates to a cushion used in an air bag gas generator for protecting passengers from impact. It also relates to an airbag gas generator using such a cushion member. Background technique [0002] Inside the housing having a gas discharge port, a gas generator for an air bag generally includes: an ignition device triggered by an impact; a gas generating agent that is ignited and burned when the ignition device is triggered so as to generate combustion gas; a filter for purifying the combustion gas and / or coolant for cooling the combustion gases. A general solid gas generating agent formed into an appropriate shape is used as the gas generating agent. If the gas generating agents are supplied as they are in the casing, the agents may be broken due to their movement inside the casing or due to vibration of the gas generator. [0003] Therefore, in a general gas generator, the gas generating agent etc. accommodated in the casing is ...
