Abstract
The invention relates to a tubular fusible member (21) extending along a longitudinal axis (AL) and for engaging in a two-lug clevis (14) and a single-lug clevis (12) in order to form a hinge (11). According to the invention, the fusible member (21) is constrained in rotation with one of the clevises (12, 14), and it presents a cross-section of shape that varies gradually between a central section and two distal sections, each distal section having reinforced thickness in its regions that extend parallel to the bending plane (PF) in which the fusible member (21) bends when it is stressed, the central section having a second moment of area relative to an axis normal to the bending plane (PF) that is greater than the second moment of area of the distal sections.
Claims5
A tubular fusible member extending along a longitudinal axis, the tubular fusible member comprising:
- a central portion, and
- two distal portions,
- wherein the fusible member presents a cross-section of shape that varies gradually between a central cross-section and two distal cross-sections, and has in each distal cross-section a thickness that is reinforced in regions of said distal cross-section extending parallel to a bending plane that contains the longitudinal axis, the central cross-section having a second moment of area relative to an axis normal to the bending plane that is greater than the second moment of area of the distal cross-sections,
- wherein the distal cross-sections (SD1, SD2) have an inside outline of elliptical shape with the major axis extending parallel to the bending plane (PF), and
- wherein the elliptical shape is an oval defined by two foci and both foci are at different points.
