The handling performance of two categories of buckles opening by means of pressure button were tested in which the following four areas were studied: (1) correlation between age and children's ability to open the buckles, (2) women’s ability to open the buckles with one and both hands, (3) women's selection of the most difficult buckle which they could accept for every day use, and (4) women's selection of age at which they felt it was permissible for children to open the buckles themselves. The results are discussed briefly. See Also B 4805
