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, in the state, comprising: a lower, support portion including a seat lowermost area with a seat lowermost surface configured to contact
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, in the state, comprising: a lower, support portion including a seat lowermost area with a seat lowermost surface configured to contact a vehicle surface to which the seat is to be mounted and defining a reference horizontal base plane;a right and a left leg attachment area each at a corresponding right or left side of the seat lowermost area, the right and left leg attachment areas extending along a common substantially horizontal axis disposed 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; anda 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 right or left leg attachment area so that each leg is rotatable about the common substantially horizontal axis between a storage position to be taken in a safety car seat mode of the seat, in which the distal ends of the legs are disposed above the reference horizontal base plane, and an operational position to be taken in a rollable mode of the seat, in which the distal ends of the legs are disposed below the reference horizontal base plane; anda right and a left locking mechanism each disposed in the corresponding legs attachment area and configured to perform at least one of the following functions on the pair of the legs associated therewith: (a) to lock at least one of the legs to the lower portion of the seat in the storage position, allowing rotation of the leg when unlocked, from the storage position into the operational position; (b) to lock at least one of the legs, when in the operational position, to the lower portion of the seat; or (c) to lock the legs to each other. 2. The baby safety seat according to claim 1, wherein each locking mechanism comprises a first locking arrangement having two locking members each for locking to the lower portion of the seat one of the front and rear legs of each pair. 3. The baby safety seat according to claim 2, wherein each locking mechanism further comprises a second locking arrangement configured to lock the legs of each pair to each other, the second locking arrangement being optionally constituted by a locking member of the first locking arrangement. 4. The baby safety seat according to claim 1, wherein at least one of the legs is configured to move under the influence of gravity along at least a part of a way between the storage position and the operational position. 5. The baby safety seat according to claim 4, wherein one of the rear and front legs is movable under the influence of gravity acting thereon before locking of the other leg thereto, and after the locking, the other leg is movable under the influence of gravity force acting thereon until both legs reach their operational position. 6. The baby safety car seat according to claim 1, wherein the lower portion has a centrally disposed base having side surfaces terminating at lower seat edges defining the lowermost area of the seat, and two side walls, each being spaced from the corresponding side surface by the leg attachment area. 7. The baby safety car seat according to claim 6, wherein in each pair of the rear and front legs, the proximal end of one of the legs is disposed adjacent to the corresponding side wall and is lockable thereto, and the proximal end of the other of the legs is disposed adjacent to the corresponding side surface of the base and is lockable thereto. 8. The baby safety car seat according to claim 1, wherein the front and rear legs form an angle therebetween whose operational value in the operational position of the legs is at least about 90°, and whose storage value in the storage position of the legs is not greater than 20°. 9. The baby safety seat according to claim 1, further comprising a handle having a handle distal end and a 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 substantially parallel to and lying above the reference horizontal plane, 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 handle rotation axis and is disposed between the head and the feet areas of the upper portion of the seat. 10. The baby safety seat according to claim 1, further comprising a handle having a handle distal end and a 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 substantially parallel to and lying above the reference horizontal base plane, 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 handle rotation axis and is disposed between the head and the feet areas of the upper portion of the seat. 11. The baby safety seat according to claim 10, wherein the operational position of the legs is combinable with the carrying position of the handle. 12. The baby safety seat according to claim 11, 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. 13. The baby safety seat according to claim 10, wherein the operational position of the legs is combinable with the carrying position of the handle.
