1. An infant seat, comprising:
a seat back member comprising at least one outer huh, the at least one outer hub having a first gear tooth structure;
a seat support member comprising an inner hub corresponding to the at least one outer hub, the inner hub being pivotably connected to the at least one outer hub to make the seat back member rotatably connected to the seat support member for forming a cross bar structure, the inner hub having a second gear tooth structure;
a seat structure connected to the seat back member and forming a seating space; and
a locking mechanism operably disposed between the seat back member and the seat support member, the locking mechanism comprising a slide gear slidable within the at least one outer hub and the inner hub for engaging with the first gear tooth structure and the second gear tooth structure at a locked position to stop the inner hub of the seat support member from rotating relative to the at least one outer hub of the seat back member, the locking mechanism translating the slide gear to the locked position or an unlocked position, the locking mechanism including an actuator having a pivot huh pivoted relative to the at least one outer hub and having at least one ramped surface structure;
wherein when the locking mechanism translates the slide gear to slide to the unlocked position, the slide gear is disengaged from the first gear tooth structure and engaged with the second gear tooth structure, to make the seat back member rotatable relative to the seat support member by a rotation of the inner hub on the at least one outer huh for adjusting a tilt angle of the seat structure, the actuator being coupled to the pivot hub so that, when actuated, the ramped surface structure drives the slide gear to the unlocked position.
