ABSTRACT:
A stowable chair armrest for a seat assembly which includes a armrest portion connected to the seat assembly through a restricted movement rotating joint which has limited rotation about a horizontal X and Y axes, the Y-axis being parallel to the length of the armrest portion and positioned above the plane of the seat cushion whereby the armrest portion is rotatable about the Y-axis approximately 180° from an elevated position of the armrest to a retracted position. When the armrest is in its use position, it cannot rotate downward about its Y-axis. However, the arm rest can be lifted upward 10° about its X-axis, wherein a flat blade connecting the armrest to a spherical pivot becomes aligned in a longitudinal chamber having a circular cross-section thus permitting the armrest portion to rotate 180° about its Y-axis to its stowed position.
