The invention refers to an airbag whose inflatable bag (1) has a gas venting hole (3) in the bag (1) sealed by a patch (14, 24, 34) which should break due to the effect of the internal pressure and has a variable thickness to reduce the volume deployed when inflated by the gas. In one of the possible embodiments of the invention, the patch (14, 24, 34) is configured in sections of different thickness. Within this configuration, the invention also comprises different variants and particularly, that using a central section of a given thickness, normally less than the other sections and of a surface depending on the desired breakage pressure. <IMAGE>
