Abstract

A gas spring end member is dimensioned for securement along an associated suspension member having an associated planar surface and at least an associated first side surface. The gas spring end member can include a base wall disposed transverse to a longitudinal axis and a bracket wall that extends longitudinally-outwardly from the base wall. The bracket wall can be adapted for operative connection to the associated suspension member such that the gas spring end member can be supported thereon with the base wall disposed in longitudinally spaced-apart relation to the associated planar surface of the associated suspension member. A gas spring assembly including such an end member can be included. A suspension system and a method of installation including such a gas spring assembly can also be included.

First claim

The invention claimed is:

1. A gas spring assembly dimensioned for securement along an associated structural component having an associated planar surface, an associated first side surface and an associated second side surface that are disposed transverse to the associated planar surface, said gas spring assembly comprising:
a flexible wall that is formed from elastomeric material and that extends circumferentially about a longitudinal axis between a first end and a second end that is spaced longitudinally from said first end, said flexible wall at least partially defining a spring chamber;
a first end member operatively connected across said first end of said flexible wall; and,
a second end member operatively connected across said second end of said flexible wall, said second end member including:
a base wall disposed transverse to said longitudinal axis;
a first bracket wall extending longitudinally outward from said base wall in a direction opposite said flexible wall and oriented in approximate alignment with said longitudinal axis;
a second bracket wall extending longitudinally outward from said base wall in said direction opposite said flexible wall and disposed in offset relation to said first bracket wall; and,
an end wall disposed in longitudinally-spaced relation to said base wall and connecting said first and second bracket walls with said base wall, said first bracket wall, said second bracket wall and said end wall at least partially defining an enclosed channel dimensioned to receive the associated structural component;

said second end member supported on the associated structural component with said base wall disposed in longitudinally spaced-apart relation to the associated planar surface of the associated structural component such that a first gap is formed between said base wall and the associated planar surface with said second end member including at least one projection extending longitudinally outward from along said base wall in a direction opposite said flexible wall, said projection including an end surface spaced longitudinally from said base wall such that a second gap that is less than said first gap is formed between said end surface and the associated planar surface when said second end member is supported on the associated structural component.
