Patent number: 10744837Abstract: An end member assembly includes first and second end member sections. The first end member section includes a first securement feature integrally formed thereon. The second end member section includes a second securement feature integrally formed therein that is dimensioned to cooperatively engage the first securement feature. In an assembled condition, the first and second end member sections are operatively engaged to substantially inhibit axial displacement therebetween. A substantially fluid-tight joint can be formed between the first and second end member sections such that an end member chamber can be formed within the end member assembly. A third end member section can be included, and can be operatively connected to the second end member section. A gas spring assembly and a suspension system are also included.Type: GrantFiled: May 31, 2016Date of Patent: August 18, 2020Assignee: Firestone Industrial Products Company, LLCInventors: Joshua R.

Patent number: 10508702Abstract: A lateral support element (304) include an element wall with a first surface facing away from an associated flexible wall (264) and a second surface facing toward the associated flexible wall. The lateral support element is disposed along the associated flexible wall such that an interface (334) is formed between an outer surface of the associated flexible wall and the second surface of the lateral support element. The interface is operative to generate a lateral spring-rate profile in an associated gas spring assembly that varies according to lateral displacement of the associated flexible wall and the lateral support element relative to one another. The interface can include a quantity of friction-reducing material and/or can be at least partially formed by a cross-sectional profile of the lateral support element that includes a convex profile segment. Gas spring assemblies and methods of assembly are also included.Type: GrantFiled: April 18, 2017Date of Patent: December 17, 2019Assignee: Firestone Industrial Products Company, LLCInventors: Stephen C.
