Abstract: End member assemblies are dimensioned for securement to an end of a flexible spring member for forming gas spring assemblies. An end member assembly can include an end member body and at least one connector fitting. The end member body includes a base section and a cap section that are secured together at a single flowed-material joint. The base section and the cap section together at least partially define a reservoir chamber within the end member body. The at least one connector fitting is at least partially embedded within the end member body. Gas spring assemblies including at least one end member assembly and suspension systems including at least one gas spring assembly are also included.

Abstract: An end member assembly (EMI) includes an end member body (400) and a support column (500). The end member body (400) includes an outer side wall and an inner side wall that together at least partially define an end member reservoir. The inner side wall at least partially defines a passage through the end member body. The support column (500) extends into the passage and is accessible from along opposing ends of the passage. A sealing element can be disposed in fluid communication between the end member body and the support column. An elongated gas damping passage can extend through the end member assembly in fluid communication with the end member reservoir. A gas spring assembly can include a flexible spring member (200) that at least partially defines a spring chamber with an end member (900) and the end member assembly (EMI) on opposing ends thereof. A restraining assembly (1000) can be secured within the spring chamber.

Abstract: An end member assembly includes an end member body and an end member insert. The end member body can include an outer side wall, an inner side wall disposed radially inward relative to the outer side wall, and a bottom wall that together with the inner side wall at least partially define a cavity. The end member insert can be supported on the end member body and selectively rotatable relative thereto. A gas spring assembly and a suspension system are also included.
