Abstract: An elastic short-pin type universal joint includes a first base, a second base, a jointer, a first elastic member, two second elastic members, and four short pins. The first base engages the second base to form a space therebetween. The jointer is received in the space between the first and the second bases. The jointer has a first bore passing through the jointer, a second bore, and a third bore. The first elastic member is received in the first bore of the jointer, and the second elastic members are received in the second bore and the third bore. The short pins are urged by ends of the first elastic member and the second elastic members to press the first base and the second base respectively. As a result, the first base is able to rotate related to the second base in all directions.

Abstract: A joint assembly joins first and second components about a common axis. The first component has a first end portion having a radially outwardly facing surface shaped to fit radially inside a second surface of a hollow second end portion of the second component to form an interface between the opposing first and second surfaces. The first and second surfaces have a concavity extending laterally with respect to the axis such that when the first and second surfaces are opposingly arranged the opposing concavities define a cavity at the interface. A retaining member is insertable into the cavity at the interface to prevent axial separation of the first and second components.

Abstract: A clip assembly for holding a component during a vehicle assembly/disassembly process. This clip assembly includes a clip structure coupled to one of a component and an associated structure of a vehicle and a corresponding receptacle structure manufactured into the other of the component and the associated structure of the vehicle. When the clip structure is engaged with the corresponding receptacle structure, the clip assembly holds the component with respect to the associated structure along three (orthogonal) axes, preventing translation of the component with respect to the associated structure in one or both directions along each axis. Along one of the axes, the engagement of the clip structure with the corresponding receptacle structure can be overcome by the application of a sufficiently high force to the component, thereby disengaging the clip structure from the corresponding receptacle structure and the component from the associated structure.
