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.

Claims (23)

1. An infant car seat, comprising:

a seat base; and

a stability leg rotatably coupled to the seat base, the stability leg comprising:

an upper leg tube;

a rotary member connected to the upper leg tube, the rotary member being movable relative to the upper leg tube to adjust a length of the stability leg;

a lower leg tube connected to the upper leg tube, the lower leg tube being movable relative to the upper leg tube to adjust the length of the stability leg, wherein the lower leg tube and the rotary member are independently movable relative to the upper leg tube.

2. The infant car seat of claim 1 , wherein the stability leg further comprises:

a first latch disposed on the rotary member and adapted to lock the rotary member relative to the upper leg tube; and

a second latch disposed on the rotary member and adapted to lock the lower leg tube relative to the upper leg tube.

3. The infant car seat of claim 2 , wherein the upper leg tube includes at least one opening, the first latch being detachably engageable with the at least one opening.

4. The infant car seat of claim 2 , wherein the lower leg tube includes at least one opening, the second latch being detachably engageable with the at least one opening.

5. The infant car seat of claim 2 , wherein the first latch is disposed at the rotary member and the second latch is disposed at the upper leg tube.

6. The infant car seat of claim 1 , wherein the rotary member further comprises:

a pivoting portion rotatably connected to the seat base; and

an encircling portion connected to the pivoting portion, the encircling portion being slidably disposed on the upper leg tube.

7. The infant car seat of claim 6 , wherein the seat base further comprises a support frame and the rotary member further comprises a contacting portion adapted to abut against the support frame for constraining rotation of the stability leg relative to the seat base in an operation mode.

8. 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.

9. The infant car seat of claim 8 , wherein the release actuator comprises a locking portion selectively engageable with an end of the stability leg.

10. The infant car seat of claim 9 , wherein the stability leg further comprises a foot housing disposed at a bottom end of the lower leg tube, the locking portion being selective engageable with the foot housing.

11. The infant car seat of claim 9 , wherein the release actuator further comprises a handle portion connected to the locking portion, 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.

12. The infant car seat of claim 11 , 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.

13. The infant car seat of claim 12 , 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.

14. The infant car seat of claim 13 , wherein the seat base comprises a reclined foot, the release actuator is movably disposed inside the reclined foot, the locking portion being engageable with the stability leg via deformation of the first resilient component when the handle portion is moved with rotation of the reclined foot.
