Chapé (French for “mantled”) is a Continental partition of the field, formed by two lines drawn from the center chief to the sides of the shield. The partition thus strongly resembles a pile inverted, or a field party per chevron; and it will conflict with either, all other things being the same. But a chapé field differs from these others in one respect: In normal usage, only the central part of the field is charged; the mantled portion of the field remains uncharged. (Despite this, there are still a number of chapé fields in Society heraldry with charges in the upper portions.)
