HEADREST SUPPORT STRUCTURE AND INFANT CARRIER THEREOF

A headrest support structure is applied to a safety seat. The headrest support structure includes a buffer mechanism. The buffer mechanism is connected to a headrest and a seat of the safety seat. Elastic deformation of the buffer mechanism provides a buffer to the headrest and the seat. The headrest support mechanism has a high safety factor and provides a buffer to the headrest and the seat during an emergency brake for accident prevention. The present application further provides an infant carrier having the headrest support structure.
