Abstract: In some countries, it is a legal requirement for babies, infants and children under a certain age and/or height to be provided with a supplemental car seat when travelling in a vehicle. Furthermore, parents and guardians of children typically make use of a pram to transport a child. However, babies and infants grow quickly and may outgrow conventional car seats and prams within a year or two years. Therefore, a parent or guardian must typically provide several car seats and prams for their child. The present disclosure provides a child car seat system (100) including an infant carrier module (200) that may be releasably docked within a docking module (300) or a wheeled frame (400) to form a car seat and a pram respectively. The infant carrier module (200) may be arranged in an upright position or a lie flat position.
