the free end portion of the fourth segment comprises a protrusion toward an interior of the second slot to hold the second bar when the second bar is received in the second slot;
wherein each respective connector is fixedly coupled with the first bar of the backrest by a fastener through the through hole of the respective connector.
10. The backrest assembly of claim 9 , further comprising:
a plurality of connecting bars disposed apart along the width direction of the backrest and fixedly coupled with the backrest, wherein a free end portion of each connecting bar in the plurality of connecting bars is to be removably coupled with a corresponding coupler of the bedstead.
11. The backrest assembly of claim 10 , wherein each respective connector in the plurality of connectors has a corresponding connecting bar in the plurality of connecting bars, wherein the corresponding connecting bar is disposed below the respective connector.
12. The backrest assembly of claim 10 , wherein the plurality of connectors comprises two, three, four or more connectors.
13. A bed frame comprising:
a backrest comprising a first bar;
a bedstead comprising a second bar; and
a plurality of connectors, each comprising first, second, third and fourth segments, wherein:
each of the second, third and fourth segments extends from a lower side of the first segment and having a free end portion;
a first slot is formed between the second and third segments to accommodate the first bar of the backrest;
a second slot is formed between the third and fourth segments to accommodate the second bar of the bedstead;
the second segment comprises a first lug extending from a first side thereof;
the third segment comprises a second lug extending from a first side thereof;
at least one of the first and second lugs is formed with a through hole; and
the free end portion of the fourth segment comprises a protrusion toward an interior of the second slot to hold the second bar when the second bar is received in the second slot;
wherein when the bed frame is assembled:
the first bar of the backrest and the second bar of the bedstead are disposed side-by-side with each other;
the plurality of connectors is spaced apart along a width direction of the backrest;
each respective connector in the plurality of connectors is fixedly coupled with the first bar of the backrest by a fastener through the through hole thereof; and
each respective connector in the plurality of connectors is snap-fitted on the second bar of the bedstead through the third and fourth segments thereof.
14. The bed frame of claim 13 , wherein of the respective connector, each of the first and second lugs is formed with a through hole to allow a fastener to pass through and to fixedly couple the respective connector with the first bar of the backrest.
