Abstract
A seat assembly having a pivot mechanism that pivotally couples first and second portions of a seat back. The pivot mechanism may have a linkage tube and a linkage pin. The linkage pin may extend through the linkage tube and may have an enlarged head that may retain the linkage pin in the linkage tube.
Claims20
A seat assembly comprising:
- a seat back having a first portion and a second portion;
- and
- an intermediate mounting bracket that is disposed between the first portion and the second portion, wherein the intermediate mounting bracket has a hole;
- a pivot mechanism that pivotally couples the first portion and the second portion, the pivot mechanism including:
- a linkage tube having a first end disposed on the first portion, a second end disposed opposite the first end, and an opening that extends from the first end to the second end, wherein the opening is narrower at the second end than at the first end;
- a linkage pin that is disposed on the second portion and that extends through the opening, wherein the linkage pin includes an enlarged head that is configured to engage the second end of the linkage tube to inhibit removal of the linkage pin from the linkage tube;
- and
- a mounting bracket bushing that is disposed in the hole between the linkage pin and the intermediate mounting bracket.

A seat assembly comprising:
- a seat back having a first portion and a second portion that are configured to rotate about an axis;
- and
- a pivot mechanism that pivotally couples the first portion and the second portion, the pivot mechanism including:
- a linkage tube that is disposed on the first portion, the linkage tube having an opening that extends from a first end to a second end, first and second indentations that extend toward the axis and are disposed proximate the second end, and first protrusion that is disposed between the first indentation and the second indentation and are arranged along a protrusion axis;
- and
- a linkage pin that is disposed on the second portion and that extends through the opening, wherein the linkage pin includes an enlarged head that is configured to engage at least one of the first and second indentations to retain the linkage pin in the linkage tube, and wherein the enlarged head does not inhibit removal of the linkage pin from the linkage tube when the enlarged head is disposed along the protrusion axis.
