• a latch mechanism operable to lock the adjustable platform with the shell body, wherein the latch mechanism includes:
• an elongated rack affixed with the shell body and including a plurality of lock positions;
• a latching element pivotally connected with the adjustable platform;
• and
• a bar linkage having a transverse segment extending generally parallel to a width direction of the base and pivotally connected with the adjustable platform, and a side segment connected with the transverse segment, the latching element being affixed with the transverse segment of the bar linkage;
• wherein the latching element is adapted to engage with one of the lock positions to lock the adjustable platform in position relative to the shell body;
• a release mechanism connected with the latch mechanism, wherein the release mechanism includes:
• a release button assembled with the adjustable platform at a position adjacent to the side segment;
• and
• a lever pivotally connected with the adjustable platform, wherein the lever has a first end adapted to contact with the release button, and a second end adapted to contact with the side segment;
• wherein the release button is operable to drive the bar linkage in rotation via the lever to disengage the latching element from the rack;
• and
• a child seat detachably installed on the base and having a seat portion and a seatback, wherein once the child seat is installed with the base and secured with the adjustable platform, the second portion of the base has a front-facing region that rises above and faces a front of the seat portion such that a leg room is delimited between the front-facing region and the front of the seat portion for receiving the legs of a child sitting on the child seat, a displacement of the child seat along with the adjustable platform concurrently causing a variation in a distance between the seat portion and the front-facing region of the second portion to adjust the leg room, and modification of an inclination of the child seat relative to the base.
