Car safety seat

A rotatable car safety seat assembly, comprising:

• an upper portion comprising a seat configured for accommodating a child, and a seat rotational element fixedly connected to the seat so as to be able to rotate therewith about a seat rotational axis;
• a lower portion configured for being mounted to a passenger's seat of the car and having a central rotational axis spaced from the seat rotational axis and located on a longitudinal axis of the lower portion;
• a movement mechanism operably connected to the seat rotational element and to the lower portion and operable to enable any of a rotational movement of the seat with the seat rotational element about the seat rotational axis and a rotational movement of the seat with the seat rotational element about the central rotational axis;
• and
• a locking mechanism operable to selectively immobilize the upper portion to the lower portion, the locking mechanism being configured to unlock the seat from the lower portion and enable rotation of the seat relative to the lower portion in one direction at a time while preventing the rotation of the seat relative to the lower portion in the opposite direction.

A rotatable car safety seat assembly, comprising:

• an upper portion comprising a seat having a frontmost point and configured for accommodating a child and a seat rotational element fixedly connected to the seat so as to be able to rotate therewith about a seat rotational axis;
• a lower portion configured for being mounted to a passenger's seat of the car and having a central rotational axis spaced from the seat rotational axis and located on a longitudinal axis of the lower portion;
• a movement mechanism operably connected to the seat rotational element and to the lower portion and operable to enable any of a rotational movement of the seat with the seat rotational element about the seat rotational axis and a rotational movement of the seat with the seat rotational element about the central rotational axis;
• and
• a locking mechanism configured to at least indirectly lock the movement mechanism and operable to selectively enable:
• a first unlocked state in which the movement mechanism is operable to enable the rotational movement of the seat with the seat rotational element about the central rotational axis of the lower portion while the locking mechanism prevents the rotational movement of the seat with the seat rotational element about the seat rotational axis, so that the frontmost point of the seat is maintained at a first distance from the central axis of the lower portion, and
• a second unlocked state in which the seat with the seat rotational element is free to rotate at least about the seat rotational axis so as to bring the frontmost point of the seat into at least one position in which it is spaced from the central axis of the lower portion to a second distance greater than the first distance.
