Abstract

A car safety seat includes a seat body, at least one knob and at least one safety belt. The seat body has at least one slot structure. The slot structure includes a plurality of first positioning slots and a plurality of guiding slots. Each of the first positioning slots is connected with another adjacent one of the first positioning slots through one of the guiding slots. The knob is movably disposed on the seat body and has a second positioning slot. The safety belt penetrates through the second positioning slot and the corresponding first positioning slot in sequence. The knob is adapted to rotate to drive the safety belt to enter the corresponding guiding slot, and the knob is adapted to move along the slot structure to drive the safety belt to pass through the guiding slot to arrive another adjacent one of the first positioning slots.

First claim

What is claimed is:

1. A car safety seat, comprising:
a seat body, having at least one slot structure, wherein the at least one slot structure comprises:
a plurality of first positioning slots, arranged with intervals in sequence; and
a plurality of guiding slots, wherein each of the plurality of first positioning slots is connected with another adjacent one of the plurality of first positioning slots through one of the plurality of guiding slots, and each of the plurality of guiding slots extends from one of the plurality of first positioning slots to another adjacent one of the plurality of first positioning slots;

at least one knob, movably disposed on the seat body and having a second positioning slot, wherein the second positioning slot is aligned with any one of the plurality of first positioning slots; and
at least one safety belt, penetrating through the second positioning slot and a corresponding first positioning slot in sequence, wherein the at least one knob is adapted to rotate to drive the at least one safety belt to enter a corresponding guiding slot, and the at least one knob is adapted to move along the at least one slot structure to drive the at least one safety belt to pass through the corresponding guiding slot to arrive another adjacent one of the plurality of first positioning slots,
wherein the seat body has at least one recession, the at least one slot structure is formed inside the at least one recession, an inner wall of the at least one recession has a plurality of limiting portions, the plurality of limiting portions are respectively corresponding to the plurality of first positioning slots, the at least one knob is adapted to be limited to any one of the plurality of first positioning slots by a corresponding limiting portion, wherein the at least one knob has two convex arc surfaces opposite to each other, each of the plurality of limiting portions has two concave arc surfaces opposite to each other, the two convex arc surfaces are adapted to lean against the two concave arc surfaces respectively to prevent the at least one knob from moving along the at least one recession, the at least one knob is adapted to rotate so as to make the two convex arc surfaces move away from the two concave arc surfaces.

2. The car safety seat as recited in claim 1 , wherein the at least one safety belt is positioned to the corresponding first positioning slot when the at least one knob rotates to a first state to make an extending direction of the second positioning slot parallel to an extending direction of the corresponding first positioning slot, and a part of the at least one safety belt enters the corresponding guiding slot when the at least one knob rotates to a second state to make the extending direction of the second positioning slot perpendicular to the extending direction of the corresponding first positioning slot.

3. The car safety seat as recited in claim 1 , wherein the seat body comprises a seating portion and a backrest connected to each other, the seating portion is located below the backrest, the at least one slot structure is formed at the backrest.

4. The car safety seat as recited in claim 1 , wherein a number of the at least one slot structure is plural, a number of the at least one knob is plural, a number of the at least one safety belt is plural, the safety belts penetrate through the slot structures and the knobs respectively.

5. The car safety seat as recited in claim 1 , wherein the seat body comprises a seating portion and a backrest connected to each other, the seating portion is located below the backrest, the at least one slot structure is formed at the seating portion.

6. The car safety seat as recited in claim 1 , comprising a wrap member, wherein the wrap member wraps the at least one safety belt.

7. The car safety seat as recited in claim 1 , wherein the at least one knob comprises a knob body and at least one fastening structure, the at least one fastening structure is disposed on the knob body and adapted to fasten the knob body to the seat body.

8. The car safety seat as recited in claim 7 , wherein the seat body has a plurality of engaging holes, the at least one fastening structure includes:
an engaging latch, slidably disposed in the knob body; and
an elastic member, connected between the engaging latch and the knob body, wherein the engaging latch is engaged into the engaging hole via an elastic force of the elastic member to fasten the knob body to the seat body, and the engaging latch is adapted to resist the elastic force of the elastic member and move away from the engaging hole.
