The invention describes an airbag module (10) comprising an airbag (12), an elongate gas generator (14) and a diffusor (16), wherein the gas generator (14) includes an outer housing (18) with outflow openings (20) distributed over the circumference (U) which define an outflow area (22), wherein the outflow area (22) of the gas generator (14) is enclosed by the diffusor (16), wherein the diffusor (16) has a central mount hole (24) into which the outer housing (18) protrudes so that the diffusor (16) circumferentially encloses an axial portion of the outer housing (18) which comprises the outflow area (22), wherein the diffusor (16) includes at least one contact face (26, 26a) and at least two gas guiding surfaces (28a, 28b) on the inner face of the diffusor (16) delimiting the mount hole (24), wherein the contact face (26, 26a) is directly adjacent to the outer housing (18) of the gas generator (14) and the gas guiding surfaces (28a, 28b) are radially spaced apart from the outer housing (18) while forming at least a first collection chamber (30a) and a second collection chamber (30b) into which gas flowing out of the outflow area (22) flows, wherein the first collection chamber (30a) opens into at least one first outlet opening (32a) and the second collection chamber (30b) opens into at least one second outlet opening (32b), wherein the first collection chamber (30a) is separated from the second collection chamber (30b) by the at least one contact face (26) specifically in the form of a separating web (34), wherein the diffusor (16) is completely arranged in an inflatable internal volume of the airbag (12), wherein the airbag (12) comprises at least a first airbag chamber (36a) and a second airbag chamber (36b) which are separated from each other, wherein the gas flowing into the first collection chamber (30a) flows, via the first outlet opening (32a), into the first airbag chamber (36a) of the airbag (12) and the gas flowing into the second collection chamber (30b) flows, via the second outlet opening (32b), into the second airbag chamber (36b) of the airbag (12).
