Description

  The present invention relates to a head protection protector used for a childcare device, and more particularly to a head protection protector that is detachably attached to a seat portion of a childcare device.

  A typical example of a child-care device used for sleeping or sitting an infant is an automobile child seat. When the child seat is used for young babies and infants, the backrest portion of the child seat is brought into a bed state and the infant is laid down for use. Younger infants need to pay particular attention to the protection of the head because the skull is underdeveloped and the head is very fragile. Therefore, in order to protect the infant's head when the child seat is used, a head protection protector has been conventionally used. JP-A-10-226252 (Patent Document 1) is disclosed as such a head protection protector.

  The head protection protector described in Patent Document 1 has left and right side wall portions that protect the infant's temporal region and a parietal wall portion that protects the infant's parietal portion, and is integrated so that these are continuous in a U-shape. Is formed. This head protection protector can cover the top and side of the infant's head and protect the infant's head from impact during a collision.
