Child carrier, and buffer assembly for a safety belt
A child carrier having a carrier body for carrying a child; a safety belt connected to the carrier body) the safety belt being capable of restraining the child seated in the carrier body; and a buffer assembly connected to the carrier body and the safety belt, the buffer assembly configured to generate a buffering movement responsive to the child carrier being subjected to an impact or sudden deceleration. Responsive to the child carrier being subjected to an impact or sudden deceleration, the buffer assembly connected to the safety belt can generate a buffering movement under the action of inertia, thereby absorbing some of the energy of the impact or sudden deceleration and preventing the safety belt from exerting an excessive restraining and pulling force on the child.
1 . A child carrier comprising:
a carrier body suitable for carrying a child, the carrier body comprising a seat portion, and a backrest portion extending away from the seat portion;
a safety belt having a first end connected to the carrier body and a second end connectible to a buckle, the safety belt extending continuously between the first end and the second end; and
a buffer assembly having a first anchoring end connected to the carrier body and a second anchoring end connected to the safety belt between the first end and the second end thereof, wherein the safety belt extends downward from the first end to the second anchoring end and extends downward from the second anchoring end to the second end, wherein the buffer assembly is configured to stretch and generate a buffering movement responsive to the child carrier being subjected to an impact or sudden deceleration,
wherein the location where the second anchoring end of the buffer assembly connects to the safety belt is closer to the seat portion of the carrier body than a location at which the first end of the safety belt is connected to the carrier body.
2 . The child carrier according to claim 1 , wherein the location where the first anchoring end of the buffer assembly connects to the carrier body differs from a location where the safety belt connects to the carrier body.
3 . The child carrier according to claim 1 , wherein the location where the first anchoring end of the buffer assembly connects to the carrier body is higher than a location where the safety belt connects to the carrier body.
4 . The child carrier according to claim 1 , wherein the carrier body has a headrest portion, and the buffer assembly is connected to the headrest portion.
5 . The child carrier according to claim 1 , wherein the buffer assembly is slidably connected to the safety belt.
6 . The child carrier according to claim 1 , wherein the buffer assembly comprises a buffering part that is able to generate a buffering movement or to break.
7 . The child carrier according to claim 6 , wherein the buffering part comprises a spring structure or an elastic flat structure, the flat structure being an elastic band or a rubber strip.
8 . The child carrier according to claim 6 , wherein the buffer assembly further comprises a connecting strap that is connected to the buffering part and the safety belt.
9 . The child carrier according to claim 8 , wherein the safety belt has a slidable protective piece, and the connecting strap is affixed to the protective piece.
10 . The child carrier according to claim 8 , wherein one end of the connecting strap forms the first anchoring end of the buffer assembly, which is connected to the carrier body, another end of the connecting strap forms the second anchoring end of the buffer assembly, which is connected to the safety belt, and the buffering part is connected to the connecting strap between the first anchoring end and the second anchoring end thereof.
11 . The child carrier according to claim 10 , wherein two ends of the buffering part are each connected to the connecting strap at different locations.
12 . The child carrier according to claim 10 , wherein the connecting strap is folded to form a loop between the first anchoring end and the second anchoring end, the loop being joined to be closed with the buffering part.
13 . The child carrier according to claim 12 , wherein the buffering part is able to break upon application of a sufficient force by the connecting strap, which opens the loop and generates a buffering effect.
14 . The child carrier according to claim 1 , wherein any of the carrier body and the safety belt is detachably connected to the buffer assembly.
15 . The child carrier according to claim 1 , wherein the safety belt is a shoulder strap.
16 . The child carrier according to claim 1 , wherein the carrier body is a child safety seat, an infant stroller, a cradle or a bassinet.
17 . The child carrier according to claim 1 , wherein the buffer assembly vertically and horizontally overlaps the safety belt.
18 . The child carrier according to claim 1 , wherein the carrier body further comprises a headrest portion, wherein the backrest portion is between the headrest portion and the seat portion.
19 . The child carrier according to claim 18 , wherein the first anchoring end of the buffer assembly is connected to the headrest portion of the carrier body and configured to move with the headrest portion relative to the backrest portion.
