1. A child safety seat for a vehicle comprising:
a base structure securable to a seat in a vehicle;
a seat shell having an interior portion configured to receive a child occupant and an exterior portion; and
a connector configured to selectively connect the seat shell to the base structure enabling relative rotational movement about a generally upstanding rotational axis, the connector further comprising:
a first connector interface disposed on the base structure with a generally C-shaped, inwardly open channel extending partially around a circular periphery, the C-shaped channel having a first and a second gap sector diametrically opposed on the periphery, the C-shaped channel encircling an upwardly open receiving area;
a second connector interface disposed on the seat shell configured for engagement with the receiving area of the first connector interface, the second connector interface having first and second flange portions fixedly extending generally outwardly from a central portion of the second connector interface and diametrically opposed along a flange axis radially aligned to the rotational axis, the flanges configured to engage the C-shaped channel when the seat shell is operably engaged with the base to enable rotation of the seat shell about an upstanding rotational axis and prevent separation of the seat shell from the base assembly by inhibiting movement of the first and second flanges along the rotational axis except when the first and second flange portions are rotationally aligned with the first and second gap sectors, such rotational positioning enabling separation of the seat shell from the base structure by movement of the seat shell axially along the rotational axis; and
a latching mechanism having first and second latching members bi-directionally moveable on a latching axis between opposing extended and retracted positions, the latching axis being aligned radially to the rotational axis and non-aligned with the flange axis, the latching members engaging the C-shaped channel when the first and second flange portions are rotationally aligned with the first and second gap sectors and the latching members are in the extended position, each latching member having a resilient member biasing the member toward the engaged position.
