Inflator for air bag
First Claim
Patent Images
1. An inflator for an air bag, comprising:
- a tubular housing including a gas discharge portion;
a first fixing member provided on an outer circumferential surface of the tubular housing for fixing the inflator to a vehicle, the first fixing member including a contacting surface formed of a strip-like member and fixed to the outer circumferential surface and having a shape that corresponds to a shape of the outer circumferential surface, and a non-contacting surface extending in a direction tangential to the outer circumferential surface from one end of the contacting surface without contacting the outer circumferential surface; and
a second fixing member having a shape that forms a supporting surface extending at an angle different from that of the non-contacting surface, the second fixing member being made of a member separate from the first fixing member, such that the inflator is mounted to the vehicle at the supporting surface by connecting the second fixing member to the non-contacting surface.

8. A method of assembling an inflator for an air bag and mounting the same to a vehicle, the inflator comprising a tubular housing containing inflation means for the air bag and a gas discharge portion and further comprising mounting means for mounting the inflator to a vehicle, wherein
the mounting means is one or more first fixing members fixed to a circumferential surface of the tubular housing and a second fixing member, the first fixing member is fixed such that it has a surface fixed to at least part of the circumferential surface of the tubular housing and a remaining surface radially extended, not contacting the circumferential surface of the tubular housing, the second fixing member has a bottom surface and a supporting surface, the supporting surface and the remaining surface of the first fixing member forming surfaces at different angles from each other when the bottom surface is fixed to the remaining surface, the method comprising steps of: -
fixing the surface of the first fixing member to the circumferential surface of the tubular housing by welding; charging a pressurized gas into the tubular housing; and welding the remaining surface of the first fixing member to the second fixing member after mounting the second fixing member to the vehicle. - View Dependent Claims (9, 10, 11)
