End member assemblies as well as gas spring assemblies and suspension systems including same

An end member assembly having a longitudinal axis and dimensioned for use in forming an associated gas spring assembly, said end member assembly comprising:

• a compliant support structure including:
• a base member that includes a first surface dimensioned for abutting engagement with an associated structure component and a second surface facing opposite said first surface, said second surface being approximately planar and extending transverse to said longitudinal axis;
• a compliant mount assembly permanently attached to said base member, said compliant mount assembly including at least two rigid elements, a base compliant element and at least two upper compliant elements, said base compliant element permanently attached to said base member, a first one of said at least two rigid elements disposed along and permanently attached to said base compliant element opposite said base member, a first one of said at least two upper compliant elements disposed along and permanently attached to said first one of said at least two rigid elements opposite said base compliant element, a second one of said at least two rigid elements disposed along and permanently attached to said first one of said at least two upper compliant elements opposite said first one of said at least two rigid elements, and a second one of said at least two upper compliant elements disposed along and permanently attached to said second one of said at least two rigid elements opposite said first one of said at least two upper compliant elements such that said at least two rigid elements, said base compliant element and said at least two upper compliant elements at least partially form a substantially fluid-tight chamber with said base member;
• said base compliant member having a base member spring rate and said at least two upper compliant elements being substantially identical and having a upper member spring rate that is different than said base member spring rate;
• and,
• an end structure supported on said compliant support structure in longitudinally-spaced relation to said base member, said end structure including an end structure wall extending transverse to said longitudinal axis and dimensioned for securement to an associated flexible spring member.
