Designing a Child's Safety Seat

There is an increasing need for understanding human elements in the development of commercially successful products for children.1-4 We have generated and utilized human factors data in the design of a child's safety seat.
 Thirty-five children, aged 6 to 42 months, were randomly selected from a Midwestern population. Anthropometric data were obtained by recording age, height, head width, shoulder width, buttock width, arm length, and leg length. Each child was photographed standing and sitting against a grid.
