A gas spring and damper assembly (AS1) comprising: a gas spring (GS1) including: a flexible spring member having a longitudinal axis (AX) and including a flexible wall extending longitudinally between first and second ends and peripherally about said axis (AX) to at least partially define a spring chamber ; a first end member operatively secured to said first end of said flexible spring member such that a substantially fluid-tight seal is formed therebetween; and, a second end member disposed in spaced relation to said first end member and operatively secured to said second end of said flexible spring member such that a substantially fluid-tight seal is formed therebetween; a damper assembly (DP1) operative to dissipate kinetic energy acting on said gas spring (GS1), said damper assembly (DP1) including a damper housing operatively connected to said second end member and a damper rod assembly operatively engaged with said damper housing for reciprocal motion relative thereto, said damper rod assembly including an elongated damper rod ; and, an end mount assembly operatively connecting said elongated damper rod and said first end member and permitting said first and second end members to move at least one of laterally and angularly with respect to one another during extension and compression of said gas spring and damper assembly (AS1), said end mount assembly including a plurality of elastomeric bushing elements (720; 722; 724) disposed in peripherally-spaced relation to one another about said longitudinal axis (AX). a gas spring (GS1) including: a flexible spring member having a longitudinal axis (AX) and including a flexible wall extending longitudinally between first and second ends and peripherally about said axis (AX) to at least partially define a spring chamber ; a first end member operatively secured to said first end of said flexible spring member such that a substantially fluid-tight seal is formed therebetween; and, a second end member disposed in spaced relation to said first end member and operatively secured to said second end of said flexible spring member such that a substantially fluid-tight seal is formed therebetween; a flexible spring member having a longitudinal axis (AX) and including a flexible wall extending longitudinally between first and second ends and peripherally about said axis (AX) to at least partially define a spring chamber ; a first end member operatively secured to said first end of said flexible spring member such that a substantially fluid-tight seal is formed therebetween; and, a second end member disposed in spaced relation to said first end member and operatively secured to said second end of said flexible spring member such that a substantially fluid-tight seal is formed therebetween; a damper assembly (DP1) operative to dissipate kinetic energy acting on said gas spring (GS1), said damper assembly (DP1) including a damper housing operatively connected to said second end member and a damper rod assembly operatively engaged with said damper housing for reciprocal motion relative thereto, said damper rod assembly including an elongated damper rod ; and, an end mount assembly operatively connecting said elongated damper rod and said first end member and permitting said first and second end members to move at least one of laterally and angularly with respect to one another during extension and compression of said gas spring and damper assembly (AS1), said end mount assembly including a plurality of elastomeric bushing elements (720; 722; 724) disposed in peripherally-spaced relation to one another about said longitudinal axis (AX). <EOS>
