43,43, and, be shaped on the seam 44 of fixing second subband 15 in its rearward end (top among Fig. 1).So the parent part 23 of design can be fixed on second subband 15, for this reason, with the terminal seam 44 that passes backward of second subband 15 in the past, reels around the rear end of base 45 then and turns back, and this end is sewn to the back side of second subband 15.

In order to utilize belt fastener 2 to make belt 1 form a closed loop, wherein belt fastener 2 is made of in a manner described buckle 11 and safety clamp 21, and at first insert the

elastic arm

17,17 of bull 12 in the opening 31 of parent part 13 this moment.This just makes inclined-plane 17a, the 17a of

elastic arm

17,17 contact with side wall ends 31a, the 31a of parent part 13.When further inserting,

elastic arm

17,17 is pushed ahead, turning-in meanwhile and lead arm 18 and enter in the neutral of leading guiding direction of advance between the wall 33,33.When insertion depth is enough, that is stumble hook 17b, the 17b of

elastic arm

17,17 passed through leading edge 32a, the 32a of parent part 13

grooves

32,32, and

elastic arm

17,17 outwards ejected and

stumble hook

17b, 17b were meshed with leading

edge

32a, 32a this moment.Hook 17b, 17b and the leading edge 32a of parent part 13

grooves

32,32, the engagement force between the 32a owing to stumble have prevented bull 12 extractions, so bull 12 and parent part 13 remain in engagement.Between their opposite end, be engaged with each other belt 1 thereby formed closed loop by bull 12 and parent part 13.

Then, the

elastic arm

25,25 of bull 22 is inserted in the parent parts 23 by opening 41, so bull 22 is connected with parent part 23 and first subband 14 is connected with second subband 15.

Embrace and be with when belt fastener 2 is applied in the baby back of the body, and buckle 11 and safety clamp 21 boths connect so that belt 1 when forming closed loop, the user belt 1 can be resembled be worn over the suspension ring on one's body, shoulder pad 4 is placed on shoulder, as shown in Figure 5.Then, the user can adjust the physical length of belt 1, makes seat 3 just in time be positioned at the front upper place of a hip.Because an end of first subband 14 is fixed on the bull 12, thus the adjustment of belt 1 physical length, for

bull

12 and 22 or

parent part

13 and 23 mutual alignments on relation do not exert an influence.Consequently, this adjustment work neither hinders the engagement between bull 22 and the parent part 23, can not bring other troubles again, is not condition with the length of adjusting

subband

14 and 15 for example.

As shown in Figure 5, the children that are carried (baby) face the user and are sitting on the seat 3, and with the waist of its both legs across the user.Back bracket 5 is adjusted into rest children's back.When using the baby to carry on the back in this way to embrace band when carrying the baby, most of weight of children is born by user's shoulder.Therefore, more light to user's burden like this than the children's that holding or carry in the arms merely situation.In addition, user's a arm is had time, and can be used for carrying a bag or similar articles.

When carrying children in this way, at belt, the pulling force of middle generation is along the directive effect that buckle 11 and safety clamp 21 are separated by children's weight.Yet, owing to stumbling of bull 12 meshed between

hook

17b, 17b and parent part 13 leading edge 32a, the 32a, and owing to mesh between leading edge 42a, the 42a of

stumble hook

25b, 25b and the parent part 23 of bull 22, so buckle 11 and safety clamp 21 can not separate.

Even throw off because of in the

elastic arm

17,17 one or two all damages the bull 12 and the engagement between the parent part 13 that make buckle 11, but safety clamp 21 is still kept engagement, keeping belt 1 to be in its ring-type, thereby prevent that children are because of falling or other are similar former thereby injured.On the other hand, if safety clamp 21 has damaged, buckle 11 continuation engagements also will prevent that children from falling so.Therefore, just in case in buckle 11 and the safety card 21 this or that thrown off, another still keeps connecting and prevents that children from falling and guarantees its safety.If the engagement of buckle 11 is thrown off, just bull 12 can overturn and leash end 1a will be subjected to the bigger power that an attempt separates it and bull 12.But, owing to termination 1a is fixed on the belt 1 with retainer ring 51, so this danger can not take place.The device that leash end 1a is fixed on the belt 1 is not only limited to retainer ring 51, can adopt the securing member of any other different structure to substitute retainer ring 51.

For ease of the bull 22 and parent part 23 engagements of safety clamp 21, first and

second subbands

14 and 15 length preferably slightly are longer than subsistence level in buckle 11 engagement back.Make them that in a small amount an additional length be arranged, not only can make safety clamp 21 be convenient to connect and throw off, and act on the thicker belt 1, reduced to act on the pulling force in

subband

14 and 15 by the pulling force that most of weight of children causes.Do like this because the effect that reduces

subband

14 and 15 fatigues is arranged, especially to their suture site, so guaranteed to be in optimum state by the

subband

14 and 15 that safety clamp 21 connects, in case because what defect buckle 11 has gone out, it is rest children reliably still.

If from then on children are carried on the back taking-up in armful band, its weight is just transferred to other place.So, the user with finger inwards by

elastic arm

25,25 parts at

groove

42,42 places that are pressed in parent part 23, so that make the hook of stumbling throw off leading edge 42a, the 42a of groove 42,42.Then just can easily bull 22 be pulled out from parent part 23, to throw off safety clamp 21.

Can untie buckle 11 easily by similar operation then.

In the above-described embodiments, the bull 12 of buckle 11 is fixed on the end 1a of belt 1, the bull 22 of safety clamp 21 is fixed on the bull 12 by first subband, the parent part 13 of buckle 11 is fixed on the other end 1b of belt 1, and the parent part 23 of safety clamp 21 is fixed on the other end of belt 1 by second subband 15.But, can not so also, and can parent part 23 be fixed on the bull 12, and bull 22 is fixed on belt 1 other end 1b by second subband 15 by first subband 14.Also can also seam 16a, the 16b bull 12 to constitute the strap length guiding mechanism and to have the belt fixed slit 16c that is used for first subband will be had, be fixed on an end 1a of belt 1, first subband 14 is fixed on the bull 12, and parent part 23 or bull 22 are fixed on the termination of first subband 14.

For example, shown in Fig. 3 and 4, one of in buckle 11 and the safety clamp 21 or both bull and parent part, can be designed to by and half bull 12 and half parent part 23 of being listed on first public base 61 combine, and by and half parent part 13 and half bull 22 of being listed on second public base 62 combine.Adopt the fastener of this structure, hold first public base 61 with a hand, and hold second public base 62, then, half bull 12 is inserted half parent part 13, and other half bull 22 is inserted in other half parent part 23 with the another hand.Result's

hook

17b, 25b and leading

edge

32a, 42a engagement of stumbling.Therefore, this structure can couple together buckle 11 and safety clamp simply.

In the utility model the foregoing description, safety clamp 21 is expressed as a kind of buckle of being made up of bull 22 and parent part 23, but safety clamp 21 also can not necessarily be used buckle, and replace for example tear drop shape, hook-type, D shape or polygon fasteners etc. with any of other various types of bindiny mechanisms.

As mentioned above, by belt fastener of the present utility model, be connected the opposite end of belt with safety clamp, make belt connect into a closed loop by the engagement buckle.Therefore, just in case one of buckle and safety clamp are unexpectedly thrown off engagement, another will keep engagement is a closed loop to keep belt.Therefore, when belt fastener is used to connect baby's back of the body and embraces the belt termination of band,, can prevent reliably that still the baby from falling even one of fastener is opened by mistake or throw off because of damage.In view of these characteristics, the user can not have anything to use this baby's back of the body to embrace band apprehensively.

Owing to, on the fastener that is fixed with a subband near-end, be provided with the strap length guiding mechanism, so the physical length of belt can be adjusted with this strap length guiding mechanism as required by belt fastener of the present utility model.Therefore, the physical length of belt can be adjusted with enclosing to grow by user's health height, in order that the seat is positioned at a least height and position of effort.In addition because an end of first subband is fixed on of buckle, so the adjustment of this belt physical length can not change between two bulls or two parent parts between locational correlation.Consequently, this adjustment neither can hinder the engagement of safety clamp, not with the operation of other troubles, for example adjusts the length of subband, as condition again.
