GAS GENERATOR INCLUDING A MULTIFUNCTIONAL FILTER
First Claim
1. A gas generator (10) for use in a safety device for motor vehicles comprising a housing and a propellant (4) contained in a combustion chamber (25) of the housing for generating a pressurized gas, said housing comprising a first housing part (40) and a second housing part (30) at least partly surrounded by said first housing part (40), an igniter (6) for igniting said propellant (4) and an annular filter (50) surrounding said combustion chamber (25) in which said propellant (4) is located, characterized in that said filter (50) has a peripheral portion (52) and a radial portion (51) and said radial portion (51) acts as filling body for said propellant (4) in said combustion chamber (25).

Abstract
The invention relates to a gas generator (10) for use in a safety device for motor vehicles comprising a housing and a propellant (4) contained in a combustion chamber (25) of the housing for generating a pressurized gas, the housing comprising a first housing part (40) and a second housing part (30) at least partly surrounded by the first housing part (40) and at least one igniter (6) for igniting the propellant (4), and an annular filter (50) surrounding the combustion chamber (25) in which the propellant (4) is located. The filter (50) comprises a peripheral portion (52) and a radial portion (51), the radial portion (51) serving as filling body for the propellant (4) in the combustion chamber (25).

8. A manufacturing process of a gas generator (10) for use in a safety device for motor vehicles, wherein said gas generator comprises a combustion chamber (25) for a propellant (4) and a filter (50) provided for retaining combustion products of said propellant, wherein said filter (50) S includes a first portion (52) and a second portion (51) and the process comprises the steps of:
- Placing said filter (50) into a lower housing part (30) of said gas generator such that, in the axial direction, said second portion (51) extends beyond said combustion chamber (25) of said gas generator (10), and filling propellant (4) into said combustion chamber (25) of said gas generator (10) using said second portion (51) of said filter (50) as filling aid.
