Abstract

A child safety seat includes a seat body, an armrest, and an actuating mechanism. The seat body includes a seat base. The armrest has a first engaging portion. The actuating mechanism is disposed on the seat body. The actuating mechanism has an actuating portion and a second engaging portion. The actuating portion is exposed from the seat body. The second engaging portion is engaged with the first engaging portion when the armrest is disposed on the seat base. The second engaging portion is disengaged from the first engaging portion when the actuating portion is actuated to move the actuating mechanism, such that the armrest is able to be detached from the seat base.

Claims

1. A child safety seat comprising:

a seat body including a seat base;

an armrest having a first engaging portion; and

an actuating mechanism disposed on the seat base, the actuating mechanism having an actuating portion and a second engaging portion, the actuating portion being exposed from the seat base, the second engaging portion being engaged with the first engaging portion when the armrest is disposed on the seat base, the second engaging portion being disengaged from the first engaging portion when the actuating portion is actuated to move the actuating mechanism, such that the armrest is able to be detached from the seat base.

2. The child safety seat of claim 1, wherein the actuating mechanism comprises an actuating member and an engaging member, the engaging member is connected to the actuating member, the actuating member provides the actuating portion, the engaging member provides the second engaging portion, and the engaging member is actuated to rotate by the actuating member when the actuating portion is actuated to move the actuating member, such that the second engaging portion is disengaged from the first engaging portion.

3. The child safety seat of claim 2, wherein the seat base has an engaging recess and an end of the engaging member is rotatably engaged with the engaging recess.

4. The child safety seat of claim 2, wherein the actuating mechanism further comprises a resilient member connected to the engaging member and the seat base.

5. The child safety seat of claim 2, wherein the seat base has a first cup holder and the actuating member is located at a bottom of the first cup holder.

6. The child safety seat of claim 5, wherein the armrest has a second cup holder and the second cup holder is stacked on the first cup holder when the armrest is disposed on the seat base.

7. The child safety seat of claim 2, wherein the second engaging portion has a curved surface, and the armrest pushes the engaging member to rotate in a direction away from the first engaging portion through the curved surface when the armrest is attached to the seat base.

8. The child safety seat of claim 1, further comprising a cover detachably disposed on the armrest.

9. The child safety seat of claim 1, wherein one of the first engaging portion and the second engaging portion is an engaging hole, and another one of the first engaging portion and the second engaging portion is an engaging protrusion.

10. A child safety seat comprising:

a seat base having a first engaging portion, the first engaging portion being a protruded member, an accommodating recess being formed in the seat base, the first engaging portion being movably disposed in the accommodating recess; and

an armrest having a second engaging portion, the second engaging portion being a recessed member, the second engaging portion being engaged with the first engaging portion in a sliding direction substantially parallel to a seat surface of the seat base when the first engaging portion protrudes from the accommodating recess, such that the armrest is detachably disposed on the seat base by a sliding manner.

11. The child safety seat of claim 10, wherein a surface of the first engaging portion is substantially flush with the seat surface when the first engaging portion sinks into the accommodating recess.

12. The child safety seat of claim 10, wherein the armrest further has a latch movably disposed on the armrest, the latch is engaged with the first engaging portion when the armrest is disposed on the seat base, and the armrest is able to be detached from the seat base when the latch is released.

13. The child safety seat of claim 12, wherein the armrest further has a resilient member connected to the latch.

14. The child safety seat of claim 10, wherein the seat base has a first cup holder, the armrest has a second cup holder, and the second cup holder is stacked on the first cup holder when the armrest is disposed on the seat base.
