Abstract:
1. A gas spring body comprising: a one-piece filament structure formed from at least one length of filament material that is disposed in a predetermined arrangement such that said filament structure extends circumferentially about a longitudinally-extending axis formed between opposing ends of said filament structure; a flexible wall at least partially defining a spring chamber and including inner and outer wall surfaces, said flexible wall formed from a quantity of elastomeric material with a first portion of said filament structure embedded in said flexible wall between said inner and outer wall surfaces thereof; and, a substantially-rigid wall including inner and outer wall surfaces, said substantially-rigid wall formed from a quantity of comparatively-rigid material that is different from said elastomeric material with a second portion of said filament structure embedded in said comparatively-rigid material of said substantially-rigid wall between said inner and outer wall surfaces thereof; said flexible wall and said substantially-rigid wall abuttingly engaging one another such that a one-piece gas spring body is formed thereby with a substantially fluid-tight seal formed between said flexible wall and said substantially-rigid wall.
