ABSTRACT:
A level indicator for a child seat equipped with a rotatable carrying handle rotatably attached thereto, and having a housing in a hub of said pivotal handle with a wall defining an interior region of said hub and an indicator member having an indicator surface. The indicator member is movably received in the interior region and the wall is formed to include a transparent window defined by an edge formed in the wall, the edge being arranged so that the indicator surface is visible through the window when the level indicator is level, with the indicator member moving entirely away from the window edge when the level indicator is not level so that the indicator surface is not visible through the window. The indicator member is disclosed as being a gravity ball that freely rotates in a curved track or a pendulum rotating in the handle.
