Abstract:
1. A piston for use in forming an associated gas spring assembly and adapted to engage an associated projection of an associated structural support member, said piston comprising: a first end including a first end wall adapted to engage an associated flexible sleeve of the associated gas spring assembly; an opposing second end including a second end wall adapted to abuttingly engage the associated structural support member, said second end disposed in longitudinally-spaced relation to said first end such that a central axis extends therebetween; an outer side wall extending at least partially between said first and second ends and suitable for rolling of the associated flexible sleeve therealong; an inner side wall disposed in radially-inward spaced relation to said outer side wall such that a chamber is at least partially defined therebetween; first and second support walls extending from said inner side wall to said outer side wall such that said chamber is at least partially segmented by said first and second support walls; and, first and second recess walls positioned between said inner and outer side walls, said first and second recess walls extending between said first and second support walls and being radially spaced from one another to at least partially define a recess adapted to receive the associated projection of the associated structural support member such that lateral loads acting on said piston can be transferred to the associated projection, and further comprising one or more support ribs connecting said second recess wall and said outer side wall.
