ABSTRACT:
For securing a generally cylindrical gas generator cartridge (14) in the housing block (10) of a belt tensioner drive unit the housing block is provided with a bore (12) in which the gas generator cartridge (14) is inserted. On the outer head portion (14a) of the gas generator cartridge incorporating an electric igniter a sleeve (18) is fitted which has at its axial end a radially inwards oriented flange (20) adjacent the end surface of the gas generator cartridge (14). At its opposite axial end the sleeve (20) is provided with rims (22) oriented radially outwards which permit insertion in the bore (12) by axial guide channels (12a, 12b) so that when the sleeve (18) is rotated in a prescribed sense of rotation the rims (22) engage in a groove (28) provided circumferentially in the bore, the guide channels (12a, 12b) merging in the groove (28).
