Abstract:
A joint assembly for use in an annular structure for limiting an extension of the joint in the direction of a load path derived from an impact and where the direction of the impact is generally in a radial direction from an inner area toward an outer area of said structure and comprising:a first member having a portion and a second member having a portion, the portions overlapping one another and arranged generally parallel to one another and secured together via securing means disposed through corresponding holes defined therein; wherein one of the overlapping portions further defines, sequentially in the direction of extension, a shear neck located closest to said holes in said first member, a pocket located beyond said shear neck and a catcher portion located at the most remote position relative to said holes in said first member, said shear neck and said pocket so that in the event of a worst case impact load, the securing means shears through the shear neck and the pocket and is then arrested by the catcher portion, thereby the extension of the joint assembly is limited and the joint assembly remains integral.
