Infant seat with angle adjustment function

An infant seat with an angle adjustment function, the infant seat comprising:

• a seat back member comprising at least one outer hub, the at least one outer hub having a first gear tooth structure formed therein;
• 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, the inner hub having a second gear tooth structure formed therein;
• a base member connected to the seat support member;
• 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 transversely 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 from rotating relative to the at least one outer hub, the locking mechanism translating the slide gear to the locked position or an unlocked position;
• wherein when the locking mechanism translates the slide gear to transversely 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 via rotation of the inner hub on the at least one outer hub for adjusting a tilt angle of the seat structure.
