Abstract

A child restraint seat includes a seat unit, a locking mechanism and a releasing handle. The locking mechanism is disposed on the seat unit and adapted to fix the seat unit onto a first external structural unit. The locking mechanism includes a latch base disposed on the seat unit, a first latching component movably disposed on the latch base, and a lock releasing component connected to the first latching component. The first latching component is adapted to move relative to a first constraining component of the first external structural unit for switching between a closed position and an open position. The releasing handle is disposed on the seat unit and connected to the lock releasing component, the releasing handle is utilized to drive the lock releasing component to move the first latching component from the closed position to the open position.

First claim

What is claimed is:

1. A child restraint seat capable of being detachably assembled with a first external structural unit, the restraint seat comprising:
a seat unit;
a locking mechanism disposed on the seat unit and adapted to fix the seat unit onto the first external structural unit, the locking mechanism comprising:
a latch base disposed on the seat unit;
a first latching component movably disposed on the latch base and adapted to move relative to a first constraining component of the first external structural unit for switching between a closed position and an open position, wherein the first latching component comprises a plate-shaped portion and an engaging portion connected with each other; and
a lock releasing component connected to the first latching component, wherein a motion of the lock releasing component relative to a restrict portion of the latch base drives deformation of the plate-shaped portion for shifting the engaging portion; and

a releasing handle disposed on the seat unit and connected to the lock releasing component, the releasing handle being utilized to drive the lock releasing component to move the first latching component from the closed position to the open position.

2. The child restraint seat of claim 1 , wherein the first latching component comprises a stretching portion belonging to the plate-shaped portion, an end of the stretching portion is fixed onto the latch base, and the engaging portion is disposed on the other opposite end of the stretching portion.

3. The child restraint seat of claim 2 , wherein the lock releasing component is rotatably disposed on the first latching component, a first end of the lock releasing component is connected to the releasing handle, and a second end of the lock releasing component different from the first end is rotated to contact against the first constraining component for deforming the stretching portion.

4. The child restraint seat of claim 3 , wherein the engaging portion is separated from the first constraining component via deformation of the stretching portion.

5. The child restraint seat of claim 3 , wherein the lock releasing component is rotatably disposed on the stretching portion, and a length of the second end of the lock releasing component is greater than a length of the engaging portion.

6. The child restraint seat of claim 2 , wherein the locking mechanism further comprises a resilient component disposed between the lock releasing component and the first latching component.

7. The child restraint seat of claim 1 , wherein the first latching component comprises a bridging portion and a crooked portion, the bridging portion belongs to the plate-shaped portion, the crooked portion whereon the lock releasing component is accommodated is disposed on a middle of the bridging portion, a first end of the bridging portion is fixed onto the latch base, and a second end of the bridging portion opposite to the first end is connected to the engaging portion.

8. The child restraint seat of claim 7 , wherein the lock releasing component is movably accommodated inside the crooked portion and slidably contacts against a restrict portion of the latch base, a slide of the lock releasing component relative to the restrict portion drives deformation of the bridging portion for shifting the engaging portion.

9. The child restraint seat of claim 7 , wherein while the lock releasing component is slid inside the crooked portion, the bridging portion is deformed and the engaging portion is separated from the first constraining component.

10. The child restraint seat of claim 7 , wherein a sunken structure of the crooked portion has two ends with different depths, and the lock releasing component having two ends with different widths is movably accommodated inside the sunken structure.

11. The child restraint seat of claim 10 , wherein while a large-width end of the lock releasing component is moved from a deep-depth end of the sunken structure to a shallow-depth end of the sunken structure, a part of the lock releasing component protrudes from the sunken structure to space the bridging portion from the latch base.
