Abstract

An infant car seat includes a seat base and a stability leg. The stability leg is rotatably disposed under the seat base. The stability leg includes an upper leg tube, a rotary member and a first latch. The upper leg tube includes at least one opening. The rotary member includes a pivoting portion and an encircling portion. The pivoting portion is rotatably connected to the seat base. The encircling portion is connected to the pivoting portion and slidably disposed on the upper leg tube. The first latch is disposed on the rotary member, and adapted to detachably engage with the at least one opening for constraining a movement between the rotary member and the upper leg tube.

First claim

What is claimed is:

1. An infant car seat, comprising:
a seat base; and
a stability leg rotatably disposed under the seat base, the stability leg comprising:
an upper leg tube, comprising at least one opening;
a rotary member, comprising:
a pivoting portion rotatably connected to the seat base; and
an encircling portion connected to the pivoting portion and slidably disposed on the upper leg tube; and
a first latch disposed on the rotary member, and adapted to detachably engage with the at least one opening for constraining a movement between the rotary member and the upper leg tube.

2. The infant car seat of claim 1 , wherein the stability leg further comprises:
a lower leg tube slidably assembled with the upper leg tube, and comprising at least one hole; and
a second latch disposed on the upper leg tube, and adapted to detachably engage with the at least one hole for constraining a movement between the upper leg tube and the lower leg tube.

3. The infant car seat of claim 1 , wherein the seat base comprises a support frame, the rotary member further comprises a contacting portion adapted to abut against the support frame for constraining a rotation of the stability leg relative to the seat base in an operation mode.

4. The infant car seat of claim 1 , wherein the seat base comprises a release actuator adapted to lock the stability leg for steadying the stability leg in a storage mode.

5. The infant car seat of claim 4 , wherein the release actuator comprises a handle portion and a locking portion connected to each other, the locking portion is engaged with or disengaged from the stability leg, the handle portion is movably disposed on the seat base and adapted to be applied by an external force for disengaging the locking portion from the stability leg.

6. The infant car seat of claim 5 , wherein the release actuator further comprises a connection portion disposed between the handle portion and the locking portion, two ends of the connection portion are respectively assembled with the handle portion and the locking portion in a movable manner.

7. The infant car seat of claim 6 , wherein the release actuator further comprises a first resilient component disposed between the handle portion and the seat base, and further comprises a second resilient component disposed between the locking portion and the seat base.

8. The infant car seat of claim 7 , wherein the seat base comprises a reclined foot, the release actuator is movably disposed inside the reclined foot, the locking portion is engaged with the stability leg via deformation of the first resilient component when the handle portion is moved with rotation of the reclined foot.

9. The infant car seat of claim 5 , wherein the locking portion has a sunken structure adapted to be applied by an external force for disengaging the locking portion from the stability leg.

10. The infant car seat of claim 1 , wherein the upper leg tube further comprises a tube body, a first blocker and a second blocker, the first blocker is disposed on a top section of the tube body and adapted to constrain a downward motion of the upper leg tube relative to the rotary member, the second blocker is disposed on a middle section of the tube body and adapted to constrain an upward motion of the upper leg tube relative to the rotary member.

11. The infant car seat of claim 1 , wherein the first latch comprises a first housing, a first button and a first lock, the first button is movably disposed on the first housing, the first lock is movably connected to the first button and disposed inside the first housing for engaging with and disengaging from the at least one opening via motion of the first button.

12. The infant car seat of claim 11 , wherein the first button is moved inside the first housing in a first direction, and the first lock is moved inside the first housing in a second direction similar to or different from the first direction.

13. The infant car seat of claim 11 , wherein the first latch further comprises a first recovering component disposed between the first housing and the first button, or between the first housing and the first lock.

14. The infant car seat of claim 11 , wherein the first button comprises a first engaging portion, and the first lock comprises a second engaging portion movably assembled with the first engaging portion.

15. The infant car seat of claim 14 , wherein the first engaging portion and the second engaging portion respectively are a pin and a slotted structure, a structural direction of the slotted structure is intersected with the first direction and the second direction.

16. The infant car seat of claim 2 , wherein the second latch comprises a second housing, a second button and a second lock, the second button is movably disposed on the second housing, the second lock is connected to the second button and movably disposed inside the second housing for engaging with and disengaging from one of the at least one hole via rotation of the second button.

17. The infant car seat of claim 16 , wherein the second latch further comprises a second recovering component disposed between the second housing and the second button.

18. The infant car seat of claim 16 , wherein the second lock is disengaged from the at least one hole via pulling down on the lower leg tube or pressing the second button.

19. The infant car seat of claim 2 , wherein the stability leg further comprises:
a foot housing disposed on a bottom of the lower leg tube, the foot housing having a window; and
an indicator, having a main body, a first indication mark and a second indication mark, the main body being movably disposed inside the foot housing, the first indication mark and the second indication mark being disposed on respective positions on the main body, one of the first indication mark and the second indication mark aligning with the window in response to motion of the main body relative to the foot housing.

20. The infant car seat of claim 19 , wherein the main body has a first end and a second end opposite to each other, the first end is protruded from or accommodated inside a bottom of the foot housing according to motion of the main body, the first indication mark and the second indication mark are disposed on the second end.

21. The infant car seat of claim 19 , wherein the main body is disposed inside the foot housing in a rotatable manner or in a slidable manner.

22. The infant car seat of claim 19 , wherein the indicator further has an elastic component disposed between the main body and the foot housing.

23. A seat base configured to removably couple to an infant car seat, the seat base comprising a release actuator positionable to engage a stability leg with a seat base of an infant car seat, the release actuator comprising:
a locking portion adapted to engage with and disengage from the stability leg; and
a handle portion connected to the locking portion and movably disposed on the seat base, the locking portion being disengageable from the stability leg via an external force applied to the handle portion,
wherein the release actuator further compromises a first resilient component disposed between the handle portion and the seat base, and further comprises a second resilient component disposed between the locking portion and the seat base, and
wherein the seat base comprises a reclined foot, the release actuator is movably disposed inside the reclined foot, the locking portion is engaged with the stabi
