SUPPORT STRUCTURE AND BABY CARRIAGE

A support structure (2) is used for supporting an infant in a supine position. The support structure (2) includes a support body (21) and a neck bolster portion (22) for supporting a neck of the infant. A bottom surface of the support body (21) is a horizontal surface. A top surface of the support body (21) is an inclined surface for supporting the infant. The neck bolster portion (22) protrudes from the inclined surface. A concave structure (23) for resisting buttocks of the infant is provided along a downward direction of the inclined surface. The support structure (2) keeps an airway open when the infant sleeps in the supine position, so as to avoid sudden infant death syndrome. The support body (21) has the concave structure (23) for resisting buttocks of the infant and providing support for buttocks and legs of the infant, thereby preventing the infant from sliding down due to gravity and providing the infant with a comfortable feeling of being contained.
