Vibration-absorbing air sheath having improved end-closing structure

Abstract

A vibration-absorbing air sheath having improved end-closing structure includes a first and a second buffering walls, at least one first and at least one second nodes, a third buffering wall and an accommodating space. The buffering walls are constructed by air columns. The first and second buffering walls are atop heat-sealed together at each of two ends of the air sheath so as to form a binding portion and a lower flat-bottomed opening. After inflation of the air columns, the air columns of the first and second buffering walls outside the binding portion and the air columns of the third buffering wall form a triangular end buffering portion. The air columns in the end buffering portion have slanted creases for their easy upward-bending so as to make the air columns in the end buffering portion spread and provide a maximized buffering area at the end of the air sheath's ends.
