  • Child-resistant buckle and buckle guard combination
    Patent number: 5205023
    Abstract: A child-resistant buckle and buckle guard combination is disclosed that relies for its effectiveness on differences in the ways young children and adults think rather than on presumed (but often non-existent) strength or dexterity differences. The child-resistant feature comprises a combination lock mechanism that incorporates at least one directly manipulated member, and, in some embodiments, at least one indirectly movable member. The device is buckled into a conventional safety belt buckle by means of a tongue-like connector. A housing or guard denies access to the push button of the conventional safety belt buckle.
