Claim 12:
13. A method for manufacturing a deflector for a diffusor of a gas generator of an airbag module, comprising the following steps of:
a. providing a tubular deflector base body having a predetermined inner diameter and a first end and a second end,
b. forming a profile in a circumferential tube section of the deflector base body by application of a profile tool by pressing or pulling the profile tool from an inner face of the deflector base body against a wall of the deflector base body in a radial direction,
c. producing through-holes in an area of the profile and producing a curved cutout at each of opposite ends of the profile,
d. cutting the profile in the axial direction from first and second ends of the profile up to a predetermined length by two cuts spaced apart from each other so that a deflector tab is produced at each of the two ends of the profile, and
e. bending both deflector tabs radially inward to an angle of from 0° to 35° with respect to a radial direction.
