Abstract
A juvenile seat includes a base having a bottom seat portion, a lower back section coupled to the base and positioned to lie at an angle relative to the bottom seat portion, and a headrest coupled to the lower back section for up and down movement relative to the base and the lower back section. The juvenile seat also includes a height-adjustment mechanism coupled to the headrest for up and down movement with the headrest to adjust the height of the headrest above the bottom seat portion. The height-adjustment mechanism is movable between a locked position to prevent up and down movement of the headrest relative to the lower back section and an unlocked position to permit up and down movement of the headrest relative to the lower back section.
Claims28
A juvenile seat comprising
- a base including a bottom seat portion,
- a lower back section coupled to the base and positioned to lie at an angle relative to the bottom seat portion,
- a headrest coupled to the lower back section for up and down movement relative to the base and the lower back section, the headrest including a back plate and first and second side wail portions coupled to the back plate and extending rearwardly therefrom and along substantially the entire length of the headrest back plate, and
- a height-adjustment mechanism for adjusting a height of the headrest above the bottom seat portion, the height-adjustment mechanism including an actuator coupled to one of the first and second side wall portions of the headrest for up and down movement with the headrest, the actuator being arranged to move between a locked position to prevent up and down movement of the headrest relative to the lower back section and an unlocked position to permit up and down movement of the headrest relative to the lower back section.

A juvenile seat comprising
- a base having a bottom seat portion,
- a lower back section coupled to the base to lie at an angle to the bottom seat portion of the base,
- a headrest coupled to the lower back section for up and down movement relative to the lower back section, the headrest being movable between a locked position prevented from moving up and down relative to the base and an unlocked position able to be moved up and down relative to the base, and
- means for adjusting a height of the headrest above the base, the height-adjusting means being coupled to a side wall of the headrest to provide for side operation of the height-adjusting means, the side wall extending rearwardly from the headrest and along substantially the entire length of the headrest.
