1. Method for the pyrotechnic rupture of a securing component (7) between two elements (8, 9), wherein the securing component:
is intended to transmit mechanical forces between said elements (8, 9) as required, and comprises a pyrotechnic rupture device (1) having a detonating cord (2) which is incorporated into said securing component (7) and able to break the latter along a predetermined separation plane (S.S) when said elements (8, 9) have to be separated from one another, wherein: oblong pre-cut zones (7.2) are formed in said securing component (7), along said predetermined separation plane (S.S), and spaced apart from one another so as to form an alternating sequence of such oblong pre-cut zones (7.2) and non-pre-cut zones (7.1) which transmit mechanical forces between said elements (8, 9); and said pyrotechnic rupture device (1) is arranged such that: in each of said non-pre-cut zones (7.1) of said securing component (7), said pyrotechnic rupture device (1) comprises a section (1.1) in which the corresponding section (2.1) of the detonating cord is arranged in an expansion tube (3), and in each of said pre-cut oblong zones (7.2) of said securing component (7), said pyrotechnic rupture device (1) comprises a section (1.2) in which the corresponding section (2.2) of the detonating cord is enclosed in a sealed manner in an inflatable sheath (5). |
