ABSTRACT:

BACKGROUND OF THE INVENTION
This invention relates to an office chair armrest, particularly to one possible to be adjusted to become horizontal or vertical according to user's need.

Some armrests are pivotally connected with armrest supporters to bend up when necessary. However their structure is rather complicated having many components, resulting in high cost.

The feature of the invention is an armrest and an L-shaped armrest supporter fixed on a side of a seat and a vertical side of a backrest. The armrest is pivotally connected to the armrest supporter so as to be swung to a horizontal condition or a vertical condition for use.
