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. 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 releasably engage with a free end of the stability leg of the infant car seat in a storage mode; 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.

2. The seat base of claim 1 , 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.

3. The seat base of claim 2 , 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.

4. The seat base of claim 3 , 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.

5. The seat base of claim 1 , 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.

6. The seat base of claim 1 , wherein the free end of the stability leg is a locking end including a locking slot.

7. The seat base of claim 1 , wherein the free end includes a foot surface positionable to contact a supporting surface proximate the infant car seat.

8. The seat base of claim 7 , wherein the foot surface of the stability leg includes a locking slot.

9. The seat base of claim 7 , wherein the foot surface of the stability leg is rotatable into an exposed position when disengaged from the locking portion.

10. 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 releasably engage with a free end of 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 free end of the stability leg is a locking end including a locking slot.

11. 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 releasably engage with a free end of 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 free end of the stability leg includes a foot surface positionable to contact a supporting surface proximate the infant car seat, the foot surface including a locking slot.
