Main pivot assembly for incorporating into a seatback pivotly secured between first and second support plates

摘要

A seat assembly including a pair of spaced apart lower sectors, each exhibiting an annular extending inner surface defining first and second aligning apertures, and an upper sector interposed between the spaced apart lower sectors and exhibiting a further annular extending inner surface defining a further aperture positioned between the aligning apertures of the lower sectors and defining a pivot point of the upper sector. A bushing and collar spacer are incorporated into the pivot point to maintain a desired spacing between the upper and lower sectors. A bushing exhibits male and female subassemblies, each further exhibiting an outer annular projecting perimeter lip such that the male bushing is installed through the aligning apertures in the upper and lower sector plates from the exterior side of a first selected lower sector, whereas the female bushing is installed from an exterior side of the other lower sector.

1. A seat assembly, comprising:
a pair of spaced apart lower sectors, each exhibiting an annular extending inner surface defining first and second aligning apertures; an upper sector interposed between said spaced apart lower sectors and exhibiting a further annular extending inner surface defining a further aperture positioned between said aligning apertures of said lower sectors and defining a pivot point of said upper sector; a bushing and collar spacer incorporated into said pivot point and which maintains a desired spacing between said upper and lower sectors; and said bushing further including a male bushing subassembly and a female bushing subassembly, said male bushing subassembly further including a central projecting cylindrical portion, from an exterior surface of which extends a plurality of linear embossments, each of said bushing subassemblies further exhibiting an outer annular projecting perimeter lip, such that said male bushing subassembly is installed through said aligning apertures in said upper and lower sectors from the exterior side of a first selected lower sector, whereas said female bushing subassembly is installed from an exterior side of the other lower sector.
