| Abstract | Recent efforts to provide effective restraint equipment for crash protection of infants in our transportation complex and to develop satisfactory flotation equipment for the little ones have revealed that there is a lack of data concerning the location of the c.g. (center of gravity) of this age group. This study was undertaken to fill this gap. Various body measurements were made on approximately 135 infants ranging in age from 2 months to 36 months and their c.g. determined from several body reference points on a specially constructed c.g. machine. Determinations of c.g. locations were made for the standing position only (actually supine) and it was found that the mean distance of the c.g. above the crotch for a 2-month-old infant (6.0 inches) is very close to that for a full-grown adult (5.9 inches). |
