A pyrotechnic circuit breaker comprising: a casing, at least two connection terminals, an internal electrical circuit connecting the two connection terminals and formed for example by an electrical conductor, an opening member, which is movable and arranged to open a part to be opened of the internal electrical circuit when moving between an initial position and a final position, so as to form at least two discrete portions of conductor after opening, a pyrotechnic actuator arranged to move the opening member from the initial position to the final position, an inner chamber defined by an internal wall formed in the casing, and receiving the part to be opened, an insulating grease, arranged in the inner chamber, wherein the insulating grease is arranged on or covers at least two predetermined parts of the internal wall.

Pyrotechnic circuit breaker

A pyrotechnic switch having a casing, at least one electrical conductor passing through the casing, a piston housed 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.

Pyrotechnic switch

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.

Inflator for a passive vehicle safety device

The invention relates to a pyrotechnic switch, which comprises, a housing formed by a first housing part that is assembled with a second housing part, and at least one pyrotechnic actuator arranged in the housing, wherein at least one out of the first housing part or the second housing part comprises a metal reinforcement and a plastic body overmolded onto the metal reinforcement, wherein the plastic body comprises, a first portion made of a first plastic material, and a second portion made of a second plastic material.

A gas generator has two pyrotechnic charges in two chambers having openings for gas outlet to the outside. Only the first chamber is provided with an igniter for first charge. The chambers are separated by a third wall with a through hole for permanent gas communication, sealed in an initial state by a cap. The cap is configured to be broken under the pressure of the combustion gases from first charge to keep the hole opened permanently and allow the combustion gases from the first charge to go via the hole kept permanently opened from a first chamber to a second chamber, where these gases induce the combustion of charge. When in an initial state, the cap is configured to go under the pressure of the combustion gases from second charge to the permanent state, in which the cap is broken to keep hole opened permanently and allow the combustion gases from said second charge to go via the hole kept permanently open from the second chamber to the first chamber, where this combustion gases induce the combustion of charge.
