  • Patent number: 11548470
    Abstract: An inflator for generating inflation gases for a safety device includes a housing having an internal cavity including a combustion chamber and a filter chamber. A filter is disposed in the filter chamber. A separating member is disposed in the housing on a first axial side of the filter and separates the filter chamber from the combustion chamber. An insulating member is disposed in the filter chamber on a second axial side of the filter. The second axial side is opposite the first axial side. The separating member is coupled to the insulating member.

  • Publication number: 20220285115
    Abstract: A pyrotechnic switch having a casing, at least one electrical conductor passing through the casing, a pistonhoused in the casing, the piston-casing assembly being designed to cut the electrical conductor at least at three separate locations, so as to form at least two free conductive strands, separate from the rest of the electrical conductor, a pyrotechnic actuator designed to force the piston to cut the electrical conductor, wherein the piston-casing assembly is designed to cut the electrical conductor such that each free strand has at least one base portion with either no or two folded wings arranged on either side of the base portion, and to create at least one free strand with two folded wings .
