Abstract
The invention relates a belt tensioner (10) for a seat belt system comprising a tensioner tube (42) for receiving and guiding a pressurizing element (44) as well as a separate generator housing (46) for receiving a gas generator (48), wherein a coupling element (50) tightly connecting the generator housing (46) to the tensioner tube (42) is provided.
Claims10
A belt tensioner for a seat belt system, comprising
- a tensioner tube (42) for receiving and guiding a pressurizing element (44) as well as
- a separate generator housing (46) for receiving a gas generator (48),
- wherein a coupling element (50) extends both into the generator housing (46) and into the tensioner tube (42) for tightly connecting the generator housing (46) to the tensioner tube (42).
A belt tensioner for a seat belt system, comprising:
- a tensioner tube (42) for receiving and guiding a pressurizing element (44) as well as
- a separate generator housing (46) for receiving a gas generator (48),
- wherein a coupling element (50) is provided for tightly connecting the generator housing (46) to the tensioner tube (42) with the generator housing (46) and the tensioner tube (42) enclosing substantially the entire coupling element (50).
A belt tensioner for a seat belt system, comprising:
- a tensioner tube (42) for receiving and guiding a pressurizing element (44) as well as
