Abstract

An infant seat includes a seat back member including an outer hub, a seat support member including an inner hub, a seat structure connected to the seat back member, and a locking mechanism including a slide gear and operably disposed on the seat back member. The inner hub is pivotably connected to the outer hub to make the seat back member rotatably connected to the seat support member for forming a cross bar structure. The slide gear is slidable within the outer and inner hubs for engaging with the outer and inner hubs to stop rotation of the inner hub on the outer hub. When the locking mechanism translates the slide gear to an unlocked position, the slide gear is disengaged from the outer hub to make the seat back member rotatable relative to the seat support member for adjusting a tilt angle of the seat structure.

First claim

What is claimed is:

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.

2. The infant seat of claim 1 , wherein the locking mechanism further comprises:
a gear pusher slidable between the at least one outer hub and the slide gear; and
wherein when the actuator is configured so that, when actuated, the actuator rotates the pivot hub so that the gear pusher is pressed against the slide gear by leaning on the ramped surface structure to drive, for driving the slide gear to the unlocked position.

3. The infant seat of claim 2 , wherein the locking mechanism further comprises:
a spring respectively connected to the slide gear and the inner hub, for biasing the slide gear to the locked position.

4. The infant seat of claim 1 , wherein the at least one outer hub has at least one ramped surface structure formed therein, and the locking mechanism further comprises:
a gear pusher slidable between the at least one outer hub and the slide gear, wherein the actuator is pivotally connected to the seat back member; and
an actuator link respectively pivoted to the actuator and the gear pusher;
wherein when the actuator is operated to rotate the gear pusher via the actuator link, the gear pusher slides to the unlocked position along the ramped surface structure disengaging the slide gear from the first gear tooth structure.

5. The infant seat of claim 4 , wherein the locking mechanism further comprises:
a spring respectively connected to the slide gear and the inner hub, for biasing the slide gear to the locked position.

6. The infant seat of claim 1 , wherein the infant seat further comprises a base member, the seat back member further comprises a seatback tube portion and a front connection portion, the at least one outer hub is connected between the front connection portion and the seatback tube portion, the seat support member further comprises a seat front portion and a support strut portion, the inner hub is connected between the seat front portion and the support strut portion, and the base member is respectively connected to the support strut portion and the front connection portion.

7. The infant seat of claim 6 further comprising:
a pivot rod pivoted to the base member and detachably connected to the seat back member, for supporting the seat back member at a sitting position when the seat back member is rotated to the sitting position.
