ABSTRACT:
A lock-release mechanism is mounted on the back of a foldable high chair to control relative movement between the chair back and the underlying seat and leg assembly. In use, the bolt-release mechanism can be actuated manually to permit the high chair to be folded from an unfolded use position to a partly folded safety stop position and a fully folded storage position.
