Abstract

The disclosure relates to a diffusor for a gas generator of an airbag module, comprising a substantially tubular base body with a longitudinal axis, a baffle cap axially connected to the base body at a first end of the diffusor and a connecting device configured at a second end of the diffusor opposite to the first end. At least one outflow opening is formed in an outer wall of the tubular base body such that gas can flow out of an interior of the diffusor substantially in parallel to a longitudinal axis in the direction of the first end and the second end from the diffusor. The baffle cap is free from an outflow opening. The disclosure further relates to a gas generator comprising such a diffusor, as well as an airbag module including such a gas generator. Moreover, a method for manufacturing the diffusor is also proved.
