A baby safety car seat convertible into a rollable baby seat includes right and left pairs of front and rear legs, a locking arrangement, and wheels. The seat has an intermediate mode in which a first leg of each pair is in its operational position while a second leg of that pair is in a different intermediate position. The locking arrangement locks the first leg in its operational position to the seat's support portion while allowing movement of the second leg between intermediate and operational positions. Alternatively/additionally, when a first leg is in its operational position, a second leg is movable between its intermediate and operational position, and the locking arrangement locks the front and rear legs of each pair to each other during movement between storage and intermediate states, and unlocks the legs from each other to allow movement of the second leg between intermediate and operational positions. |

1. A baby safety car seat having, at least when in use, a state in which the baby safety car seat is convertible into a rollable baby seat, the baby safety car seat, at least in the state, comprising:
a lower, support portion including a seat lowermost area configured to contact an external surface to which the seat is to be mounted, and defining an imaginary horizontal base plane, and two, right and left, leg attachment areas on respective right and left sides of the lowermost area; an upper, seating portion having a front, head area and a rear, feet area, the head area being spaced from the imaginary horizontal base plane to a distance greater than the feet area; a right and a left pair of front and rear legs, the legs of each pair having distal ends associated with wheels and proximal ends articulated to the seat lower portion at the corresponding leg attachment area, each leg being rotatable between a storage position to be taken in a safety car seat mode of the seat, in which the distal end of the leg is disposed above the imaginary horizontal base plane, and an operational position to be taken in a rolling-carrier mode of the seat, in which the distal end of the leg is disposed below the imaginary horizontal base plane; the baby safety car seat further having an intermediate mode, in which a first one of the legs of each pair is in the operational position whilst the second leg of that pair is in the intermediate position, in which the distal end of that leg is disposed below said imaginary horizontal base plane but which is other than the operational position of this leg; and a locking arrangement configured for locking the first leg in the operational position to the support portion prior to the movement of said second leg between the intermediate and operational positions. |
