Abstract
Description
Technical Field
[0001] The utility model relates to a baby carriage, and more particularly to a seat-back assembly of a baby carriage.
Background Art
[0002] Baby carriages are common products in the growth process of infants and young children. Generally, a baby carriage on the market at present includes a frame and a seat-back assembly arranged on the frame. The seat-back assembly generally includes a seat part and a backrest part that can rotate relative to the seat part. An angle adjustment device for adjusting the angle between the backrest part and the seat part is provided between the backrest part and the seat part, so as to adjust the inclination angle of the backrest, enabling a child to sit in a more comfortable posture.
[0003] However, the angle adjustment device of the backrest of a traditional baby carriage generally adopts a gear engagement structure, that is, tooth grooves are arranged on the seat part and the backrest part, a gear that can move horizontally and engage with the tooth grooves on both of them simultaneously is arranged in the space enclosed by the two, and an operation switch is arranged on the backrest part. A pull rope for pulling the gear to disengage from the tooth groove on the seat part is arranged between the operation switch and the gear, and a return spring for pushing the gear to reset is also arranged. When the angle of the backrest needs to be adjusted, the gear is pulled by the pull rope to disengage from the tooth groove on the seat part, and at this time, the backrest can be rotated to adjust the angle. When the set angle is reached, the gear resets under the action of the return spring and engages with the tooth grooves on the seat part and the backrest part again. Although this structure can adjust the angle of the backrest, it has a relatively complex structure and a relatively high cost.
[0004] Therefore, the present utility model is precisely produced based on the above deficiencies.
Content of the Utility Model
[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a seat-back assembly of a baby carriage with a simple structure and low cost. By adopting this seat-back assembly of the baby carriage, the inclination angle of the support part can be conveniently adjusted to meet the comfortable sitting posture of a child.
[0006] The present utility model is realized through the following technical solutions:
[0007] A child stroller seat-back assembly includes a seat portion 1 that can be connected to a frame 100 and a backrest portion 2 connected to the rear side of the seat portion 1. The backrest portion 2 includes a front side portion 21 that can be connected to the frame 100 and a support portion 22 whose lower end is connected to the rear side of the seat portion 1 and is used to support the child's back. A connecting cloth 23 is provided between the front side portion 21 and the support portion 22 for connecting the two and can be folded or unfolded when the support portion 22 moves relative to the front side portion 21. A first chain tooth 24 is provided on the front side portion 21, a second chain tooth 25 is provided on the support portion 22, and a zipper head 26 that can pull the two together or pull them apart is also provided between the first chain tooth 24 and the second chain tooth 25. When the zipper head 26 pulls the first chain tooth 24 and the second chain tooth 25 together, the connecting cloth 23 is folded and the support portion 22 closes to the front side portion 21, reducing the angle between the support portion 22 and the seat portion 1. When the zipper head 26 pulls the first chain tooth 24 and the second chain tooth 25 apart, the connecting cloth 23 unfolds and the upper part of the support portion 22 moves backward, increasing the angle between the support portion 22 and the seat portion 1.
[0008] A pocket 27 is provided on the support portion 22. Layers communicating with the pocket 27 are provided on the left and right sides of the connecting cloth 23, and an adjusting belt 28 that can slide therein is provided in the layers. One end of each adjusting belt 28 is connected to the frame 100, and a buckle head 29 that is hidden in the pocket 27 and can be buckled with each other is provided at the other end of each adjusting belt 28. When the two adjusting belts 28 are buckled with each other, the adjusting belts 28 push the upper part of the support portion 22 forward to reduce the angle between the support portion 22 and the seat portion 1.
[0009] The first chain tooth 24 is U-shaped and has an opening facing downward.
[0010] An observation window is provided on the upper side of the connecting cloth 23, and when the connecting cloth 23 is in the unfolded state, a child in the child stroller can be observed through the observation window.
[0011] A covering cloth 20 that can cover the observation window and can be lifted to open the observation window is also provided on the connecting cloth 23.
[0012] The front side portion 21 includes side edges 211 on both sides. An upper side piece 212 integrated with the side edges 211 is connected to the upper part of the side edges 211, and a canopy 3 is connected to the upper side piece 212.
[0013] The canopy 3 and the upper side piece 212 are detachably connected by a zipper.
[0014] There are two zipper heads 26.
[0015] The support portion 22 includes a hard board. A cloth piece that wraps the hard board by sewing is provided on the outer side of the hard board. The cloth piece is connected to the seat portion 1 and the connecting cloth 23, and the pocket 27 is provided on the cloth piece.
[0016] Compared with the prior art, the utility model has the following advantages:
[0017] 1. When it is necessary to increase the angle between the support part and the seat part of the utility model, the zipper puller is pulled to open the first and second chain teeth. At this time, the connecting cloth between the support part and the front side part can be unfolded, and the upper part of the support part can move backward to become an inclined state, and the angle between the support part and the seat part becomes larger, and the child can lie obliquely on the support part. When it is necessary to reduce the angle between the support part and the seat part, the first and second chain teeth are zipped together through the zipper puller. At this time, the upper part of the support part moves forward and is connected to the front side part, and the connecting cloth is folded and retracted. At this time, the angle between the support part and the seat part becomes smaller, and the child can sit in the baby stroller in a relatively straight posture. Therefore, the user only needs to open or zip the first and second chain teeth through the zipper puller to adjust the inclination angle of the support part, so that the child can sit in a comfortable posture. The whole angle adjustment operation is very convenient and fast, avoiding the problem of high cost caused by the traditional gear engagement structure, and is suitable for popularization and application.
[0018] 2. A pocket is provided on the support part of the utility model, and adjustment belts that can slide therein are provided in the interlayers on both sides of the connecting cloth. One end of the two adjustment belts is connected to both sides of the frame, and the other end is connected with a buckle. When the zipper puller opens the first and second chain teeth, at this time the connecting cloth is unfolded, and the angle between the support part and the seat part is at the maximum angle. At this time, the buckles on the adjustment belts are separated from each other at an interval. When the upper part of the support part is pushed forward, the buckles can be made to approach each other and buckle together. At this time, the angle between the support part and the seat part is slightly reduced, and the adjustment belts buckled together make the inclination angle of the support part positioned. Therefore, the arrangement of the adjustment belts and the buckles enables the support part to have an additional angle gear for the user to choose, and the buckles can also be stored in the pocket, and the overall structure is simple and compact.
[0019] 3. The utility model has a simple structure, low cost, and convenient angle adjustment operation of the support part, and is suitable for popularization and application.

Specific Embodiment
[0025] The present utility model will be further described below in conjunction with the accompanying drawings:
[0026] As Figures 1 to 5 shown, a seat-back assembly for a baby stroller includes a seat portion 1 that can be connected to a frame 100 and a backrest portion 2 connected to the rear side of the seat portion 1. The backrest portion 2 includes a front side portion 21 that can be connected to the frame 100 and a support portion 22 whose lower end is connected to the rear side of the seat portion 1 and is used to support the back of a child. A connecting cloth 23 is provided between the front side portion 21 and the support portion 22 for connecting the two and can be folded or unfolded when the support portion 22 moves relative to the front side portion 21. A first chain tooth 24 is provided on the front side portion 21, a second chain tooth 25 is provided on the support portion 22, and a zipper head 26 is further provided between the first chain tooth 24 and the second chain tooth 25 for pulling the two together or separating them. When the zipper head 26 pulls the first chain tooth 24 and the second chain tooth 25 together, the connecting cloth 23 is folded and the support portion 22 approaches the front side portion 21, reducing the angle between the support portion 22 and the seat portion 1. When the zipper head 26 separates the first chain tooth 24 and the second chain tooth 25, the connecting cloth 23 unfolds and the upper part of the support portion 22 moves backward, increasing the angle between the support portion 22 and the seat portion 1. When it is necessary to increase the angle between the support portion 22 and the seat portion 1, the zipper head 26 is pulled to separate the first chain tooth 24 and the second chain tooth 25. At this time, the connecting cloth 23 between the support portion 22 and the front side portion 21 can unfold, and the upper part of the support portion 22 can move backward to become an inclined state, and the angle between the support portion 22 and the seat portion 1 becomes larger, and the child can lie obliquely on the support portion 22. When it is necessary to reduce the angle between the support portion 22 and the seat portion 1, the first chain tooth 24 and the second chain tooth 25 are pulled together by the zipper head 26. At this time, the upper part of the support portion 22 moves forward and connects to the front side portion 21, and the connecting cloth 23 is folded and closed. At this time, the angle between the support portion 22 and the seat portion 1 becomes smaller, and the child can sit in the baby stroller in a relatively straight posture. Therefore, the user only needs to pull the zipper head 26 to separate or pull together the first chain tooth 24 and the second chain tooth 25 to adjust the inclination angle of the support portion 22, so that the child can sit in a comfortable posture. The whole angle adjustment operation is very convenient and fast, and it also avoids the problem of high cost caused by using the traditional gear engagement structure.
[0027] In order to more conveniently adjust the angle of the support portion 22, the first chain tooth 24 is U-shaped and the opening faces downward, and there are two zipper heads 26. The user can simultaneously pull the first chain tooth 24 and the second chain tooth 25 to the two sides, or can simultaneously pull the first chain tooth 24 and the second chain tooth 25 to the inside, making the operation more convenient and fast.
[0028] like Figures 1 to 5 As shown, the support portion 22 is provided with a pocket 27, and the connecting cloth 23 is provided with interlayers on the left and right sides thereof that are connected to the pocket 27. The interlayer is provided with an adjusting strap 28 that can slide therein, and one end of each adjusting strap 28 is connected to the frame 100, and the other end of each adjusting strap 28 is provided with a buckle joint 29 that is hidden in the pocket 27 and can be buckled with each other. When the two adjusting straps 28 are buckled with each other, the adjusting straps 28 push the upper portion of the support portion 22 to move forward to reduce the angle between the support portion 22 and the seat portion 1. When the zipper head 26 pulls apart the first chain teeth 24 and the second chain teeth 25, the connecting cloth 23 is unfolded, and the angle between the support portion 22 and the seat portion 1 is at the maximum angle. At this time, the buckle joints 29 on the adjustment belt 28 are separated from each other by a distance. When the upper part of the support portion 22 is pushed forward, the buckle joints 29 can be brought close to each other and buckled together. At this time, the angle between the support portion 22 and the seat portion 1 is slightly reduced, and the buckled adjustment belt 28 allows the tilt angle of the support portion 22 to be positioned. Therefore, the setting of the adjustment belt 28 and the buckle joint 29 allows the support portion 22 to add an angle gear for the user to choose, and the child's back can be leaned on the support portion 22 at multiple angles, and the buckle joint 29 can also be stored in the pocket 27, and the overall structure is simple and compact.
[0029] The support part 22 comprises a hard board to provide sufficient support for the child's back. A cloth piece is provided on the outside of the hard board to wrap the hard board by sewing, the cloth piece is connected to the seat part 1 and the connecting cloth 23, and the pocket 27 is provided on the cloth piece.
[0030] like Figure 3 As shown, the upper side of the connecting cloth 23 is provided with an observation window through which the child in the stroller can be observed when the connecting cloth 23 is unfolded. When the adult pushes the stroller, the adult can observe the child in the stroller through the observation window, which is convenient for watching. The connecting cloth 23 is also provided with a cover cloth 20 that can cover the observation window and can be lifted to open the observation window. When the child in the stroller is sleeping, the cover cloth 20 can cover the observation window.
[0031] like Figure 1 and Figure 5 As shown, the front side portion 21 includes side edges 211 on both sides, and the upper side pieces 212 are connected to the upper side pieces 211, and the upper side pieces 212 are connected to the ceiling 3, which can be used to block the sun and wind. The ceiling 3 and the upper side pieces 212 are detachably connected by a zipper.
[0032] The embodiment is described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiment, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the present purpose.
