BACKGROUND
[0002] The present disclosure relates to child restraints and, in
particular, to an infant carrier that can be mounted on an
underlying base held in place on a passenger seat of a vehicle.
More particularly, the present disclosure relates to a system for
anchoring an infant carrier to an underlying base in one mode and
to a stroller frame in another mode.
SUMMARY
[0003] According to the present disclosure, a child restraint
system includes a base adapted to set on a passenger seat in a
vehicle and an infant carrier. In illustrative embodiments, the
infant carrier can be mounted in a stationary position either on
the base or on a stroller frame.
[0004] In illustrative embodiments, the infant carrier includes a
seat shell, a front shell anchor, and a rear shell anchor. The
front and rear shell anchors are used to mate the seat shell to an
underlying base that is adapted to set on a vehicle seat. In
contrast, only the rear shell anchors are used to mate the seat
shell to a stroller frame to form a seat in a juvenile stroller.
The front shell anchor is coupled to the seat shell for pivotable
movement about an anchor-pivot axis relative to the seat shell
between a base-mating position engaging the base to hold a front
portion of the seat shell on the base and a base-releasing position
disengaging the base to free the front portion of the seat shell to
be separated from the base. The rear shell anchor is coupled to the
seat shell and is arranged to lie in spaced-apart relation to the
front shell anchor and configured to move laterally along an
anchor-movement line relative to the seat shell between a
base/stroller-mating position engaging either the base or the
stroller and base/stroller-releasing position disengaging the base
and the stroller.
[0005] In illustrative embodiments, the child restraint further
includes an anchor controller coupled to the seat shell. The anchor
controller can be moved by a caregiver back and forth relative to
the seat shell between a locked position in which the front shell
anchor is in the base-mating position engaging the base and the
rear shell anchor is in the base/stroller-mating position engaging
either a base or a stroller frame and an unlocked position in which
the front shell anchor is in the base-releasing position
disengaging the base and the rear shell anchor is in the
base/stroller-releasing position disengaging either the base or the
stroller.
[0006] In illustrative embodiments, the anchor controller includes
a release handle, an anchor-mover link, and an anchor-pivot link.
The anchor-mover link is arranged to extend between and
interconnect the release handle and the anchor-pivot link to cause
the anchor-mover link and the anchor-pivot link to move together
with the release handle. The anchor-mover link is arranged to
interconnect the release handle and the rear shell anchor to cause
the first rear shell anchor to move along the anchor movement line
inwardly from the base/stroller-mating position to the
base/stroller-releasing position in response to movement of the
release handle in a rearward direction away from the seat shell.
The anchor-pivot link is arranged to interconnect the release
handle and the front shell anchor to cause the front shell anchor
to pivot about the anchor-pivot axis in a clockwise direction from
the base-mating position to the base-releasing position in response
to movement of the release handle in the rearward direction away
from the seat shell.
[0007] In illustrative embodiments, the rear shell anchor includes
a retaining pin and a pin collar. The retaining pin is coupled to
the pin collar to move therewith and arranged to extend outwardly
through a pin slot formed in the anchor-mover link to engage and
mate with the base/stroller-anchor retainer when the rear shell
anchor is in the base/stroller-mating position. The retaining pin
is arranged to be withdrawn from and lie in spaced-apart relation
to the base/stroller-anchor retainer when the rear shell anchor is
in the base/stroller-releasing position.
[0008] In illustrative embodiments, the anchor-mover link includes
a translation beam, a pin mount, and a pin mover. The translation
beam is arranged to extend between and interconnect the release
handle and the pin mount to cause the pin mount to move with the
release handle. The pin mover is appended to the pin mount to move
therewith and is arranged to extend away from pin mount toward the
pin collar. The anchor-pivot link is appended to the pin mover to
lie in spaced-apart relation to the pin mount to move therewith.
The translation beam, the pin mount, the pin mover, and the
anchor-pivot link move together in response to movement of the
release handle relative to the seat shell.
[0009] In illustrative embodiments, the pin mount is configured to
provide a relatively flat surface that engages with the pin collar
when the rear shell anchor is in the base/shell-mating position.
The pin mover is configured to provide a ramped surface that
engages the pin collar to cause the pin collar to move along the
ramped surface and move inwardly as the anchor-mover link moves
with the release handle relating to the seat shell.
[0010] Additional features of the present disclosure will become
apparent to those skilled in the art upon consideration of
illustrative embodiments exemplifying the best mode of carrying out
the disclosure as presently perceived.

are configured to mate with rear shell anchors 31, 32 when seat
shell 20 is mounted on stroller frame 16 and rear anchors 31, 32
are in the base/stroller-mating positions.
[0027] Anchor controller 30 of anchor system 19 is configured to
provide means for moving both the front shell anchors 21, 22 about
anchor-pivot axis 24 and the rear shell anchors 31, 32 along
anchor-movement line 26 relative to seat shell 20 at the same time
in response to one actuation force (F) so that seat shell 20 is
free to be separated from one of base 14 and stroller frame 16 at
the option of a caregiver as suggested in FIG. 4. Anchor controller
30 includes a release handle 42, first and second anchor-mover
links 51, 53, and first and second anchor-pivot links 52, 54 as
suggested in FIGS. 2 and 6. Release handle 42 is coupled to seat
shell 20 to move back and forth relative to seat shell 20 between a
locked position shown in FIG. 3 and an unlocked position shown in
FIG. 5.
[0028] First anchor-mover link 51 is arranged to interconnect
release handle 42 and first rear shell anchor 31 to cause first
rear shell anchor 31 to move inwardly along anchor-movement line 26
toward second rear shell anchor 32 from the base/stroller-mating
position to the base/stroller-releasing position in response to
movement of release handle 42 in a rearward direction 46 away from
seat shell 20. First anchor-pivot link 52 is arranged to
interconnect release handle 42 and first front shell anchor 21 to
cause first front shell anchor 21 to pivot about anchor-pivot axis
24 in a clockwise direction 44 from the base-mating position to the
base-releasing position in response to movement of release handle
42 relative to seat shell 20 in the rearward direction 46.
[0029] As shown in FIG. 6, second rear shell anchor 32 is
spaced-apart laterally from first rear shell anchor 31. Second
anchor-mover link 53 is arranged to interconnect release handle 42
and second rear shell anchor 32 to cause second rear shell anchor
32 to move inwardly along anchor-movement line 26 toward first rear
shell anchor 31 from the base/stroller-mating position to the
base/stroller-releasing position in response to movement of release
handle 42 relative to seat shell 20 in the rearward direction
46.
[0030] Second front shell anchor 22 is spaced-apart laterally from
first front shell anchor 21 as shown in FIG. 6. Second anchor-pivot
link 54 is arranged to interconnect release handle 42 and second
front shell anchor 22 to cause second front shell anchor 22 to
pivot about anchor-pivot axis 24 in clockwise direction 44 from the
base-mating position to the base-releasing position in response to
movement of release handle 42 relative to seat shell 20 in the
rearward direction 46.
[0031] As suggested in FIG. 6, first anchor-pivot link 52 is
appended to first anchor-mover link 51 to move therewith. In one
example, first anchor-pivot link 52 and first anchor-mover link 51
cooperate to form a monolithic member. In another example, first
anchor-mover link 51 is configured to resist deformation and
bending while first anchor-pivot link 52 is configured to deform
and bend in a predictable manner when the release handle 42 is
moved relative to seat shell 20.
[0032] As suggested in FIG. 6, second anchor-pivot link 54 is
appended to second anchor-mover link 53 to move therewith. In one
example, second anchor-pivot link 54 and second anchor-mover link
53 cooperate to form a monolithic member. In another example,
second anchor-mover link 53 is configured to resist deformation and
bending while second anchor-pivot link 54 is configured to deform
and bend in a predictable manner when the release handle 42 is
moved relative to seat shell 20.
[0033] A caregiver (not shown) applies an actuation force (F) to
release handle 42 to move handle 42 from the locked position shown
in FIG. 3 to the unlocked position shown in FIG. 5. Actuation force
(F) is sufficient to overcome a set of anchor-bias springs 61, 62,
63, and 64 included in anchor controller 30 as shown in FIG. 6.
First anchor-bias spring 61 interconnects seat shell 20 and first
front shell anchor 21 to cause first front shell anchor 21 to be
biased normally to move in a counterclockwise direction 48 about
anchor-pivot axis 24 to assume the base-mating position. Second
anchor-bias spring 62 interconnects seat shell 20 and second front
shell anchor 22 to cause second front shell anchor 22 to be biased
normally to move in counterclockwise direction 48 about
anchor-pivot axis 24 to assume and remain in the base-mating
position.
[0034] Third anchor-bias spring 63 interconnects seat shell 20 and
first rear shell anchor 31 to cause first rear shell anchor 31 to
be biased normally to move away from second rear shell anchor 32
along anchor-movement line 26 to assume the base/stroller-mating
position. Fourth anchor bias spring 64 interconnects seat shell 20
and second rear anchor 32 to cause second rear anchor 32 to be
biased normally to move away from first rear shell anchor 31 along
anchor-movement line 26 to assume and remain in the
base/stroller-mating position.
[0035] First rear shell anchor 31 is substantially similar to
second rear shell anchor 32, and thus, only first rear shell anchor
31 will be discussed in detail. First rear shell anchor 31 includes
a retaining pin 66, a pin collar 68, and spring retainer 70 as
shown in FIG. 7. Retaining pin 66 is coupled to pin collar 68 and
arranged to extend away from second rear shell anchor 32 through a
pin slot 72 formed in first anchor-mover link 51 and into a pin
passageway formed in the scat shell 20 to engage and mate with a
companion stroller-anchor retainer 37 when first rear shell anchor
31 is in the base/stroller-mating position and used to retain the
seat shell 20 on the stroller frame 16. When first rear shell
anchor 31 is in the base/stroller-releasing position, retaining pin
66 is arranged to be withdrawn from and in spaced-apart relation to
the companion stroller-anchor retainer 37. Spring retainer 70 is
appended to pin collar 68 and arranged to extend away from pin
collar 68 and retaining pin 66 and configured to receive third
anchor-bias spring 63 therein.
[0036] First anchor-mover link 51 includes a translation beam 74, a
pin mount 76, and a pin mover 78 as shown in FIG. 7. Translation
beam 74 is arranged to extend between and interconnect release
handle 42 and pin mount 76 to cause pin mount 76 to move with
release handle 42. Pin mover 78 is appended to in mount 76 to move
therewith and is arranged to extend away from pin mount 76 toward
second rear shell anchor 32. First anchor-pivot link 52 is appended
to pin mover 78 to lie in spaced-apart relation to pin mount 76 to
move therewith. As release handle 42 moves relative to seat shell
20, translation beam 74, pin mount, pin mover 78, and first
anchor-pivot link 52 move therewith.
[0037] As shown in FIGS. 7 and 8, pin mount 76 is formed to include
pin slot 72 therein. Pin mount 76 is configured to provide a
relatively flat surface 76F that engages with pin collar 68 when
first rear shell anchor 31 is in the base/shell-mating position. As
a result, retaining pin 66 is arranged to extend out of seat shell
20 and engage stroller-anchor retainer 37 of stroller frame 16.
[0038] Pin mover 78 is illustratively a ramp providing a ramped
surface 78A as shown in FIGS. 7 and 8. As first anchor-mover link
51 moves away from first and second front anchors 21, 22, pin mover
78 engages pin collar 68 to cause pin collar 78 to move along
ramped surface 78 and move inwardly toward second rear shell anchor
32 as suggested in FIGS. 7 and 8. Once actuator force (F) is
removed, anchor-bias spring 63 normally urges pin collar 68 to
slide back down ramped surface 78 and cause release handle 42 to
move relative to seat shell 20 to return to the locked
position.
[0039] When first rear shell anchor 31 is in the
base/stroller-mating position and seat shell 20 is coupled to
stroller frame 16, retaining pin 66 is arranged to extend through
the pin passageway formed in the seat shell 20 to engage and mate
with the companion stroller-anchor retainer 37 of stroller frame
16. When first rear shell anchor 31 is in the
base/stroller-releasing position in the stroller mode, retaining
pin 66 is arranged to be withdrawn from and lie in spaced-apart
relation to the companion stroller anchor retainer 37 of stroller
frame.
[0040] When first rear shell anchor 31 is in the
base/stroller-mating position and seat shell 20 is coupled to base
14, retaining pin 66 is arranged to extend through the pin
passageway formed in the seat shell 20 to engage and mater with a
side wall included in base 14 and extend into second anchor
receiver 233 formed in that side wall. When first rear shell anchor
31 is in the base/stroller-releasing position in the vehicle mode,
retaining pin 66 is arranged to be withdrawn from and lie in
spaced-apart relation to the second anchor receiver 233 formed in
that side wall.
