Abstract

A child seat assembly has a base to rest on a vehicle seat, a seat shell, and a recline mechanism that selectively permits adjustment of the seat shell between first and second recline positions and includes a recline positioner, pin, biasing element, and handle. The recline positioner has first and second portions defining the first and second recline positions, respectively. The pin is movable between a released position and an engaged position in which the pin is configured to engage the first or second portion to retain the seat shell in the corresponding first or second recline position. The biasing element is coupled to the pin and configured to bias the pin to the engaged position. The handle is operable to move the pin from the engaged position to the released position in which the seat shell is movable between the first and second recline positions.

12. The reclinable child seat assembly of claim 11, wherein the release handle includes two arms, each arm operable to move a respective one of the two pins from the engaged position to the release position.

13. The reclinable child seat assembly of claim 11, wherein the recline positioners are on and laterally spaced apart across the support base, and wherein the pins, the leaf springs, and the release handle are mounted to the seat shell beneath the seating surface.

14. The reclinable child seat assembly of claim 1, wherein the recline positioner is on the support base, and wherein the pin, the leaf spring, and the release handle are mounted to the seat shell.

15. A reclinable child seat assembly comprising:

a support base configured to rest on a dedicated seat of a vehicle;

a seat shell defining a seat back, a seat bottom, and a seating surface and being supported on the support base; and

a recline mechanism configured to selectively permit adjustment of the seat shell relative to the support base between a first recline position and a second recline position different than the first recline position, the recline mechanism including

(a) a recline positioner having a first portion defining the first recline position and a second portion defining the second recline position,

(b) a pin movable between a released position and an engaged position and configured to engage, in the engaged position, a selected one of the first and second portions of the recline positioner to retain the seat shell in the corresponding first or second recline position,

(c) a biasing element coupled to the pin and configured to bias the pin to the engaged position,

(d) a release handle operable to move the pin from the engaged position to the released position out of engagement with the first and second portions of the recline positioner, and

(e) a driving ramp and a contact surface, wherein the release handle is operable to move the driving ramp and the contact surface relative to one another to move the pin from the engaged position to the released position,
