Claims20
A juvenile seat comprising:
- a seat bottom and
- a seat back arranged to extend upwardly away from the seat bottom, the seat back including a backrest coupled to the seat bottom, a movable headrest coupled to the backrest for up-and-down movement along a headrest-travel path relative to the backrest, and a headrest-height controller arranged to extend between and interconnect the backrest and the movable headrest to selectively block up-and-down movement of the movable headrest relative to the backrest,
- wherein the backrest includes a backrest shell and a support frame coupled to the backrest shell and having a first side frame member formed to include a first guide channel and a plurality of first apertures opening into the first guide channel and a second side frame member formed to include a second guide channel and a plurality of second apertures opening into the second guide channel, each aperture in the plurality of first apertures being aligned with a corresponding aperture in the plurality of second apertures, and
- wherein the headrest-height controller includes a first lock pin configured to extend through one of the plurality of first apertures formed in the first side frame member, an opposite, second lock pin configured to extend through one of the plurality of second apertures formed in the second side frame member, and an adjustment handle coupled to the movable headrest for movement relative to the movable headrest between an unactuated position in which the first and second lock pins extend into the one of the plurality of first apertures and the one of the plurality of second apertures to block up-and-down movement of the movable headrest relative to the backrest and an actuated position in which the adjustment handle pulls the first and second lock pins inwardly toward one another and out of the one of the plurality of first apertures and the one of the plurality of second apertures so that the movable headrest is free for up-and-down movement relative to the backrest, and
- wherein the adjustment handle is formed to include a pair of slots, each lock pin includes a lock-pin guide post that extends into a respective one of the pair of slots, and each slot of the pair of slots includes a vertical portion and an angled portion.

A juvenile seat comprising:
- a seat bottom and
- a seat back arranged to extend upwardly away from the seat bottom, the seat back having a backrest coupled to the seat bottom, a movable headrest coupled to the backrest for up-and-down movement along a headrest-travel path relative to the backrest, and a headrest-height controller arranged to extend between and interconnect the backrest and the movable headrest to selectively block up-and-down movement of the movable headrest relative to the backrest,
- wherein the backrest includes a backrest shell and a support frame coupled to the backrest shell and having a side frame member formed to include a guide channel that extends substantially parallel to the headrest-travel path and a plurality of apertures opening into the guide channel,
- wherein the headrest-height controller includes a lock pin arranged to lie in the guide channel and extend through one of the plurality of apertures to block up-and-down movement of the movable headrest relative to the backrest when the headrest-height controller is in an unactuated position, the lock pin is configured to move laterally out of the one of the plurality of apertures to slide within the guide channel so that the movable headrest is free for up-and-down movement relative to the backrest when the headrest-height controller is in a actuated position,
- wherein the headrest-height controller includes an adjustment handle coupled to the movable headrest for movement relative to the movable headrest, the adjustment handle being configured to pull the pin out of the one of the plurality of apertures,
- wherein the adjustment handle is formed to include an angled slot, and wherein the lock pin includes a lock-pin guide post that extends into the angled slot, and
- wherein the angled slot includes a vertical portion and an angled portion connected to the vertical portion, and the vertical portion is located above the angled portion.
