Abstract:
1. A safety lighter to initiate combustion comprising: an output lighting relay; a lighter body having a cylindrical void along an axis; a pyrotechnic slide-in module comprising an igniter for initiating combustion of the output lighting relay, the pyrotechnic slide-in module being able to be displaced in the cylindrical void from a safety position (Ps), providing isolation between the pyrotechnic initiator and the output lighting relay, to an initiation position (Pi) configured to initiate combustion of the output lighting relay; a first o-ring seal between the pyrotechnic slide-in module and the lighter body to isolate, in the safety position (Ps), the pyrotechnic slide-in module from the output lighting relay to be initiated; and a retaining mechanism to maintain the pyrotechnic slide-in module in the safety position (Ps), wherein the pyrotechnic slide-in module comprises: a tubular pyrotechnic chamber having a first end and a second end, the tubular pyrotechnic chamber comprising the igniter and a pyrotechnic delay initiated by the igniter; a closure wall, perpendicular to the axis, closing the first end of the pyrotechnic chamber, the closure wall having a first hole, wherein gases pass from the tubular pyrotechnic chamber to a cell of a cap configured to close the first hole.
