A baby safety car seat convertible into a rollable baby seat, and comprising a front, head area and a rear, feet area, the head area being higher than the feet area; a right and left pair of front and rear legs, and a handle. The legs of each pair have distal ends associated with wheels and proximal ends articulated to the seat at corresponding leg attachment area. Both legs are rotatable relative to each other and to the seat between a storage position to be taken in a safety car seat mode of the seat, and an operational position to be taken in a rolling-carrier mode of the seat. The legs can have an intermediate position between the storage and operational position, and can be rotatable between the intermediate and operational positions, at least partially under the influence of gravity force.

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 with a seat lowermost surface configured to contact an external surface to which the seat is to be mounted, and defining a reference horizontal base plane, and two leg attachment areas at two sides of the lowermost area and above the seat lowermost surface;an upper, seating portion having a front, head area and a rear, feet area, the head area being spaced from the reference horizontal base plane to a distance greater than the feet area;a right and 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 lowermost area at the corresponding leg attachment area, each leg being rotatable from 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 reference horizontal base plane, via an intermediate position into an operational position to be taken in a rollable mode of the seat, in which the distal end of the leg is disposed below the plane; in each of the right and left pairs of front and rear legs, each of the front and rear legs is configured to rotate in the same direction as the other leg of the same pair when moving into the storage position and when moving into the operational position, and at least one of the legs in each of the right and left pairs being configured for moving at least along a part of its way between the storage and the operational positions under the influence of gravity; anda locking mechanism configured for locking a first leg of each pair of legs to a second leg of the same pair of legs in at least one of the storage position, the intermediate position, or the operational position of the first leg, and unlocking the first and second legs from each other in at least one other position of the first leg. 2. The baby safety seat according to claim 1, wherein at least one of the rear and front legs, when in the storage position, has its distal end disposed under the head area of the upper seating portion. 3. The baby safety seat according to claim 1, wherein the leg attachment areas have a common substantially horizontal axis disposed above the seat lowermost area, the legs being rotatable about the axis at locations spaced from each other therealong. 4. The baby safety seat according to claim 3, wherein the head area of the seating portion is disposed further from the common substantially horizontal axis than the feet area thereof, and the distal ends of both of the legs of each pair of legs, when in the storage position, are disposed closer to the head area than to the feet area of the seat. 5. The baby safety seat according to claim 1, wherein the rear and front legs have different length defined by a distance between their proximal and distal ends. 6. The baby safety seat according to claim 3, wherein the distal ends of the front and rear legs of each pair, when in the storage position, are spaced to different distances from the common substantially horizontal axis. 7. The baby safety seat according to claim 1, wherein the locking mechanism is configured to perform at least one of the following functions: (a) to lock at least one of the legs to the lower portion of the seat in at least one of the storage position or operational position, allowing rotation of the leg when unlocked, between the storage and operational positions to lock the legs to each other in at least one of the storage, operational, or intermediate positions of at least one of the legs. 8. The baby safety seat according to claim 1, further comprising a handle having a handle distal end at which the seat is to be carried by a user, and handle proximal end at which the handle is attached to the lower portion of the seat so as to be rotatable about a substantially horizontal handle rotation axis, between a storage position in which the handle distal end is disposed adjacent to the head area of the upper portion of the seat and at least a carrying position, in which the handle has an orientation transverse to the substantially horizontal rotation axis and is disposed between the head and the feet areas of the upper portion of the seat. 9. The baby safety seat according to claim 8, wherein the operational position of the legs is combinable with the carrying position of the handle. 10. The baby safety seat according to claim 8, wherein the handle is rotatable from the storage or carrying position to a pushable position in which the distal end of the handle is disposed at a distance from the head area of the seat that is at least not shorter than a distance between the head and the feet areas, to bring the seat into a pushable-carriage mode. 11. The baby safety seat according to claim 10, wherein the handle is extendible in the pushable-carriage mode to increase the distance from the distal end to the base plane. 12. The baby safety seat according to claim 2, wherein both legs of each pair, when in the storage position, have their distal ends disposed under the head area of the upper seating portion. 13. The baby safety seat according to claim 7, wherein the locking mechanism is configured to perform both of the functions (a) and (b). 14. The baby safety seat according to claim 8, wherein the carrying position of the handle is substantially vertical. 15. The baby safety seat according to claim 14, wherein the operational position of the legs is combinable with the carrying position of the handle. 16.
