This is made possible in particular by the absence of metallic material in the shaft 607, which makes it possible to provide a resilient member, such as the aforementioned member 625, for the axial fixing of the shaft 607.
• the fact of limiting the number of items to report on the 607 tree prevents their accidental loss on the production line.
• the absence of metallic material also makes the temporary pivot shaft inexpensive and easy to manufacture, so that it can advantageously constitute a disposable or recyclable part, after one or more uses, on one or more vehicles.
• the off-center hinge assembly has the following characteristics:
• the temporary pivot shaft (607) is free of metallic material, the temporary pivot shaft is made at least partially, preferably at least predominantly, of plastic material, preferably polyamide.
• the temporary pivot shaft is made in one piece in one piece, in the same material.
• the temporary pivot shaft further comprises at least two axial stops, turned in a mounting direction of the temporary pivot shaft, for axially positioning the knuckles relative to each other when these knuckles are mounted by the intermediate of the temporary pivot shaft.
• the temporary pivot shaft further comprises a resilient member configured to have a radially constricted configuration, wherein the temporary pivot shaft can be mounted on the hinge so that the hinges are pivotally mounted thereagainst; having a radially expanded configuration, wherein, when the temporary pivot shaft is mounted, the resilient member forms an axial stop rotated in a disassembly direction of the temporary pivot shaft, so that the resilient member opposes the disassembly of the temporary pivot shaft of the knuckles; and elastically returning to the radially expanded configuration when it is placed in a radially constricted configuration.
• the resilient member comprises two resilient legs defining between them an axial deflection notch opening at an axial end of the temporary pivot shaft, the passage from the radially extended configuration to the radially constricted configuration corresponding to a closer of at least 1 one of the legs resilient to the other at the axial notch of deflection.
• the temporary pivot shaft comprises: a rod section, of smaller diameter than pivoting orifices formed through the knuckles, and through which the temporary pivot shaft is accommodated when the knuckles are pivotally mounted via it ; and an extremal manipulation part, comprising an extremal head of generally discoid shape, and a gripping section extending between the extremal head and the stem section, the section of gripping having a diameter smaller than that of the extremal head and greater than that of at least one of the pivoting orifices.
• the off-center hinge assembly comprises a door stop device having a through-mounting port
• the temporary pivot shaft includes a detent portion of the door-stop device on the temporary pivot shaft, for axially fixing the door stop device on the temporary pivot shaft by threading the door stop device onto the detent section via the mounting hole.
