[0002] Baby carriers have become an essential vehicle for children to travel. In order to adapt to growing children, existing baby carriers are provided with headrests of adjustable height. However, when adjusting the height of the existing baby carriers, the height of the shoulder straps for restraining children does not change, so that when children of relatively high height use the existing baby carriers, their shoulders cannot be well matched with the shoulder straps.

[0003] In addition, the existing ways of adjusting the height of the headrest of baby carriers are not flexible enough, the connection ways are limited, and the operation is not convenient.

[0004] Baby or child carriers such as child safety seats and baby strollers are usually equipped with a seat cushion structure (which can be called a "small seat cushion") to ensure the size matching and comfort when a toddler or child is sitting. When in use, this small seat cushion can be installed on the child seat, for example, by threading straps or attaching buckles, and can be detached from the child safety seat for easy cleaning or replacement. In addition, to ensure the head comfort of children when in use, the small seat cushion is usually provided with a headrest part for the child to rest on when sitting.

However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited by the specific embodiments disclosed below.

[0149] In addition, in the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present application.

[0150] In the present application, unless otherwise clearly specified and defined, the terms "mounted", "connected", "connected to", "fixed", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. However, indicating a direct connection means that there is no connection relationship constructed through an excessive structure between the two connected main bodies, and they are only connected through the connection structure to form a whole. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0151] In the present application, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0152] The present application provides an infant carrier 1 that can be used for an infant or a child to ride. The infant carrier 1 can be an infant carrier basket, a child safety seat, a baby carriage, or other infant carriers. The first embodiment of the present application will be described below.

[0153] As Figure 1 and Figure 2As shown, the infant carrier 1 may have: a backrest 50; a headrest 10 formed with a shoulder strap hole 110; a safety belt 2 attached to the seat shell 1. The safety belt 2 may include a shoulder strap 20 and an adjustment strap 21. The adjustment strap 21 is not necessary and can be removed. The shoulder strap 20 may extend through the shoulder strap hole 110. The back surface of the headrest 10 may have a first connector 30, and the front surface of the backrest 50 may have a second connector 40. The first connector 30 is attached to the second connector 40 in a height-adjustable manner.

[0154] There may be two shoulder straps 20 configured. The two shoulder straps 20 correspond to the shoulder parts of the child. The front sides of the two shoulder straps 20 may be detachably snapped with the crotch strap 23 of the infant carrier through a buckle 25, for example, so that when in the locked state, neither the outward pulling movement nor the inward retracting movement of the adjustment strap 21 is allowed. The structures of the safety belt 2 and the buckle 25 are involved in many known technologies and will not be elaborated here.

[0155] The backrest 50 extends substantially vertically. Optionally, the backrest 50 may be slightly tilted backward. The headrest 10 may be provided at a higher position of the backrest 50 to support and protect the head of the occupant. The shoulder straps 20 may be formed into two and symmetrically arranged in front of the backrest. The lower ends of the shoulder straps 20 may be fixed to the seat cushion of the infant carrier 1, and the upper ends of the shoulder straps 20 may be fixed to the backrest 50 of the infant carrier 1. The shoulder straps 20 may slide relative to the shoulder strap holes 110 to adjust the length exposed in front of the infant carrier 1. The shoulder straps 20 may be used to restrain the shoulders of the occupant to protect the safety of the occupant.

[0156] The shoulder strap holes 110 may be provided at a lower position of the headrest 10 so as not to interfere with the support of the headrest 10 for the head of the occupant. In this embodiment, the first connector 30 may be one of a male hook-and-loop fastener and a female hook-and-loop fastener, and the second connector 40 may be the other of a male hook-and-loop fastener and a female hook-and-loop fastener. It can be understood that the hook-and-loop fastener generally consists of two parts. The one with hooks formed on the surface is usually called the male hook-and-loop fastener, and the one with loops formed on the surface is usually called the female hook-and-loop fastener. As Figure 3 shown, the first connector 30 and the second connector 40 may be formed into squares with equal areas. The side length of the square may be, for example, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm or greater than 10 cm. The first connector 30 and the second connector 40 may also be formed into squares of different sizes. For example, the area of the first connector 30 is smaller than the area of the second connector 40. Specifically, the side length of the first connector 30 may be, for example, half of the side length of the second connector 40. This application is not limited thereto. The first connector 30 and the second connector 40 may be other forms, such as rectangles, ellipses, circles, etc.

[0157] As Figure 1 and Figure 2As shown, when the headrest 10 is set at a lower position and a higher position, since the shoulder strap holes 110 are provided on the headrest 10, the upper end of the shoulder strap 20 moves as the headrest 10 moves, so that the position of the shoulder strap 20 can also be adjusted according to the change in the height of the occupant. Such a structure makes the baby carrier 1 have better adaptability and is very convenient to operate.

[0158] The second embodiment of the present application will be described below.

[0159] See Figures 4 - 5 , the first connecting member 30 may be an adjusting member 310. A plurality of through adjusting holes 311 may be formed on the adjusting member 310. The adjusting member 310 may be a PE board. As Figure 5 shown, 4 adjusting holes 311 may be formed on the adjusting member 310, and every 2 adjusting holes 311 form a row. Other numbers of adjusting holes 311 may also be formed on the adjusting member 310. The adjusting member 310 may be joined to the rear surface of the headrest 10 at the outer periphery, and only in contact with the headrest 10 at the middle position (for example, the position where the adjusting holes 311 are located), and there may be a certain gap between the middle position and the headrest 10 under the application of force.

[0160] The second connecting member 40 may be an adjusting belt 410. One end of the adjusting belt 410 may be fixed to the backrest 50, and the other end of the adjusting belt 410 may be fixed or detachably connected to the backrest 50. When the other end of the adjusting belt 410 is set to be detachably connected to the backrest 50, the headrest 10 can be separated from the backrest 50, so that operations such as cleaning, maintenance, replacement, etc. can be conveniently carried out. The adjusting belt 410 passes through one of the adjusting holes 311 into the space between the adjusting member 310 and the headrest 10, and passes out of the adjusting member 310 through another adjusting hole 311, so that the adjusting member 310 exerts a holding force on the adjusting belt 410. When each row of adjusting holes 311 is set to be more than 2 (for example, 4), the adjusting belt 410 can pass through and out of each adjusting hole 311 in a row in turn, so that the magnitude of the holding force can be changed. As Figure 4 shown, the adjusting belt 410 may be set to two side by side ( Figure 5 although only one adjusting belt 410 is shown in, it can be understood that the two adjusting holes 311 on the right side may also be provided with the adjusting belt 410), and the present application is not limited thereto. The adjusting belt 410 may also be set to one or more than two.

[0161] See Figure 5As the adjustment strap 410 passes through the adjustment hole 311, the adjustment strap 410 is subjected to a holding force (or clamping force) from the adjustment member 310. Optionally or additionally, the width of the adjustment hole 311 is set to be close to the thickness of the adjustment strap 410, so that the adjustment strap 410 is subjected to a holding force from the adjustment hole 311. In addition, the portion of the adjustment strap 410 between the adjustment member 310 and the headrest 10 may also be subjected to a holding force provided by both the adjustment member 310 and the headrest 10. When the height of the headrest 10 needs to be adjusted, the headrest 10 is moved by overcoming the resistance (holding force) of the adjustment member 310 and the adjustment hole 311 to the headrest 10.

[0162] A third embodiment of the present application will be described below.

[0163] See also Figures 6 - 7 The first connector 30 may include a connecting belt 320 and a connecting piece 330. One end of the connecting belt 320 may be fixed to the headrest 10. The other end of the connecting belt 320 may have a connecting piece 330. The connecting piece 330 may be formed of hard plastic and may be substantially perpendicular to the connecting belt 320.

[0164] The second connecting member 40 may include an adjustment belt 410 and a fastener 420. One end of the adjustment belt 410 may be fixed to the backrest 50, and the other end of the adjustment belt 410 may be fixedly or detachably connected to the backrest 50. When the other end of the adjustment belt 410 is arranged to be detachably connected to the backrest 50, the headrest 10 may be separated from the backrest 50, so that operations such as cleaning, maintenance, and replacement can be conveniently performed. The two ends of the adjustment belt 410 are located at different heights. The fastener 420 is movably arranged on the adjustment belt 410. Sufficient holding force may be formed between the adjustment belt 410 and the fastener 420. The connecting belt 320 may pass through the fastener 420, and the connecting piece 330 may cooperate with the fastener 420 to prevent the headrest 10 from being separated from the backrest 50.

[0165] Specifically, if Figure 6 As shown, the fastener 420 may be a "目"-shaped fastener. The "目"-shaped fastener may be understood as a fastener whose shape is close to the Chinese character "目" (eye), and which has three holes arranged in a vertical direction. The adjustment belt 410 may pass through one hole (e.g., the lowermost hole) of the "目"-shaped fastener, and the size of the connecting piece 330 is larger than the hole of the "目"-shaped fastener. In this way, since the connecting piece 330 is blocked by the fastener 420 at the rear side of the fastener 420, the headrest 10 is attached to the backrest 50 and cannot be separated.

[0166] In this embodiment, the connecting band 320, the connecting piece 330, the adjusting band 410, and the fastener 420 can all be symmetrically formed into two. The adjusting band 410 is generally vertically oriented to provide an adjustable height range for the headrest 10. The connecting band 320 can have a relatively short length, which can be set to facilitate the connecting piece 330 passing through the fastener 420 and not cause the headrest 10 to significantly wobble relative to the backrest 50.

[0167] The connecting piece 330 can be formed into a rectangular sheet. Optionally, the connecting piece 330 is arranged to be able to pass through the hole of the eye-shaped fastener by rotating a specific angle, so that the headrest 10 can be separated from the backrest 50.

[0168] The fourth embodiment of the present application will be described below. The fourth embodiment is similar to the second embodiment, and only the different parts will be described below.

[0169] See Figure 8 , a plurality of holes 411 are formed along the length direction of the adjusting band 410. These holes 411 can cause the surface of the adjusting band 410 to form a certain undulation, thereby increasing the holding force with the connecting piece 330. Although Figure 8 only shows one adjusting band 410, preferably, there are two adjusting bands 410 arranged side by side. The adjusting member 310 can be formed into two arranged side by side at the same height. The adjusting member 310 can be connected to the headrest 1 only on one side, that is, the adjusting member 310 can form a connecting portion 340 only on one side. Optionally, the two adjusting members 310 form the connecting portion 340 only on the inner side (the side close to each other). In this way, the other sides (the upper side, the lower side, and the outer side) of the adjusting member 310 can be away from the headrest 10, thereby allowing the headrest 10 to be separated from the backrest 50 by a limited distance. This is beneficial to the operation convenience when adjusting the height of the headrest 10. Using two separate adjusting members 310 can save materials and keep the headrest 10 stably attached to the backrest 50 when the adjusting member 310 is fixed to the headrest 10 only on one side. The above structure in this embodiment can also be applied to other embodiments.

[0170] The fifth embodiment of the present application will be described below. The fifth embodiment is similar to the second embodiment, and only the different parts will be described below.

[0171] See Figure 9 , although Figure 9 only shows one adjusting band 410, preferably, there are two adjusting bands 410 arranged side by side. The adjusting member 310 can be formed into two arranged side by side at the same height. The headrest 10 can include a pocket 120. A part of each adjusting member 310 ( Figure 9 the outer side in) can be inserted into the pocket 120. The pocket 120 is, for example, a sheet covering the headrest 10, and a part of the outer periphery of the sheet (for example, for Figure 9The left pocket 120 in the figure may be the upper side, the lower side and the left side) is attached to the headrest 10, while the remaining part of the periphery (e.g., for Figure 9 The left pocket 120 in the embodiment may be the right side) is not attached to the headrest 10 so that an opening can be formed. In order to facilitate the insertion of the adjustment member 310 into the pocket 120, the adjustment member may be bendable.

[0172] The headrest 10 may include a fixing strap 130. The fixing strap 130 may be a fabric strap. One end of the fixing strap 130 may be fixed to the headrest 10, for example, to a position of the headrest 10 located in the pocket 120. The other end of the fixing strap 130 may be detachably connected to a first surface of the adjustment member 310 (for example, a surface of the adjustment member 310 facing the backrest 50) (for example, connected by a hook and loop fastener) to form a first attachment portion 140.

[0173] Figure 9 The adjustment member 310 and a portion of the fixing belt 130 are shown as dotted lines, which indicates that the portion is blocked by the pocket 120 and is not visible.

[0174] The headrest 10 can be detachably connected to the second surface of the adjustment member 310 (for example, connected by a hook and loop fastener) to form a second attachment portion 150. The second surface is, for example, the surface of the adjustment member 310 facing the headrest 10. In other words, the first surface and the second surface are opposite. The second attachment portion 150 can be located at a position approximately in the center of the adjustment member 310. The second attachment portion 150 can also be located at other positions. Although in Figure 9 In the embodiment, the second attachment portion 150 is formed on the left side of the adjustment hole 311. It is understood that the second attachment portion 150 may also be formed on the right side of the adjustment hole 311. Through the first attachment portion 140 and the second attachment portion 150, the adjustment member 310 can be separated from the headrest 10 while forming a stable and reliable connection with the headrest 10, and preventing the headrest 10 from shaking.

[0175] Figure 9 The second attachment portion 150 in FIG. 1 is shown as a dotted line, which indicates that the second attachment portion 150 is formed on the surface of the adjustment member 310 facing the headrest 10 and is not visible.

[0176] The adjusting belt 410 may be formed with a plurality of holes 411 along its length direction. These holes 411 may cause the surface of the adjusting belt 410 to form certain undulations, thereby increasing the holding force between the adjusting belt 410 and the connecting piece 330.

[0177] Although Figure 9Two adjusting members 310 separated from each other are shown. It can be understood that the adjusting members 310 can also be formed as a single entity. At this time, pockets 120 can be respectively formed on the left and right sides of the adjusting member 310 formed as a single entity, and two first attachment portions 140 can be respectively provided on both sides, and a second attachment portion 150 can be centrally provided in the middle of the adjusting member 310. Optionally, the adjusting member 310 can be formed with a connecting portion 340 as in the fourth embodiment.

[0178] The sixth embodiment of the present application will be described below. The sixth embodiment is similar to the fifth embodiment, and only the different parts will be described below.

[0179] Referring to Figure 10 , in this embodiment, the fixing strap 130 may not be formed. A part of each adjusting member 310 (for example, the left part of the left adjusting member 310) can be inserted into the pocket 120 and detachably connected to the headrest 10 through elements such as buttons (for example, buttons are provided on the adjusting member 310 and holes cooperating with the buttons are provided at corresponding positions on the pocket 120) or snap fasteners to form the first attachment portion 140.

[0180] Figure 10 A part of the adjusting member 310 and the fixing strap 130 in Figure 10 is shown as a dashed line, which means that this part is blocked by the pocket 120 and is not visible. Similarly,

[0181] The headrest 10 may include a restraint ring 160. The adjusting member 310 can pass through the restraint ring 160, so that the restraint ring 160 restrains and fixes the adjusting member 310 to a certain extent. The part of the adjusting member 310 passing through the restraint ring 160 and the part inserted into the pocket 120 can have a smaller width (such as the dimension in the up and down direction as shown in Figure 10 ) to facilitate the adjusting member 310 passing through the restraint ring 160 and inserting into the pocket 120.

[0182] In this embodiment, through the first attachment portion 140 and the second attachment portion 150, the adjusting member 310 can be separated from the headrest 10 while being able to form a stable and reliable connection with the headrest 10 and prevent the headrest 10 from shaking. The first attachment portion 140 provided in the pocket 120 is less likely to be accidentally opened, thus ensuring that the adjusting member 310 and the headrest 10 will not be separated accidentally.

[0183] The seventh embodiment of the present application will be described below. The seventh embodiment is similar to the sixth embodiment, and only the different parts will be described below.

[0184] Referring to Figure 11, in this embodiment, the adjusting member 310 can be formed as one, but the present application is not limited thereto. The adjusting member 310 can be formed as a rectangle (i.e., having a consistent width), but the present application is not limited thereto. Both ends of the adjusting member 310 are detachably connected to the headrest 10 through the first attachment portion (button) 140. Two buttons can be provided at each end of the adjusting member 310 to form a stable fastening force, but the present application does not limit the number of buttons. Two parts of the first attachment portion (button) 140 are respectively arranged at corresponding positions on the adjusting member 310 and the headrest 10.

[0185] Although Figure 11 only shows one adjustment strap 410, this embodiment can have two adjustment straps 410 arranged side by side and symmetrically. Figure 11 The first attachment portion 140 in

[0186] is shown as a dotted line, which means that the first attachment portion 140 is blocked by the adjusting member 310.

[0187] In this embodiment, through a plurality of first attachment portions (buttons) 140, while the adjusting member 310 can be separated from the headrest 10, it can also form a stable and reliable connection with the headrest 10, prevent the headrest 10 from shaking, is convenient to operate, and has a low cost.

[0188] The following will describe the eighth embodiment of the present application. The eighth embodiment is similar to the seventh embodiment, and only the different parts will be described below.

[0189] Refer to Figure 12 , in this embodiment, the adjusting member 310 can be formed as one, but the present application is not limited thereto. Two fixing arms 312 extend from both ends of the adjusting member 310 respectively in a direction perpendicular to its length. The two fixing arms 312 extending from each end of the adjusting member 310 extend in opposite directions. In other words, each end of the adjusting member 310 can be formed as a T shape. Connection holes 170 can be formed on the headrest 10. The number and position of the connection holes 170 can correspond to the number and position of the fixing arms 312. Since the adjusting member 310 can be bent, the fixing arms 312 can be respectively inserted into the corresponding connection holes 170, thereby fixing the position of the headrest 10 through the adjusting member 310. At the same time, the headrest 10 can be separated from the adjusting member 310 by bending the fixing arms 312.

[0190] Although Figure 12 only shows one adjustment strap 410, this embodiment can have two adjustment straps 410 arranged side by side and symmetrically. Figure 12 A part of the fixing arm 312 in

[0191] In this embodiment, buttons may not be provided. For other parts of this embodiment, reference may be made to the seventh embodiment.

[0192] In this embodiment, through the cooperation of the connecting hole 170 and the fixing arm 312, while the adjusting member 310 can be separated from the headrest 10, it can also form a stable and reliable connection with the headrest 10 and prevent the headrest 10 from shaking, which is convenient to operate.

[0193] The ninth embodiment of the present application will be described below. The ninth embodiment is similar to the seventh embodiment, and only the different parts will be described below.

[0194] See Figure 13 , in this embodiment, the adjusting member 310 may be formed as one, but the present application is not limited thereto. The adjusting member 310 may be formed as a rectangle (i.e., having a uniform width), but the present application is not limited thereto. Both ends of the adjusting member 310 are detachably connected to the headrest 10 through the second attachment portion 150. The second attachment portion 150 may be a hook-and-loop fastener. One hook-and-loop fastener may be provided at each end of the adjusting member 310, but the present application does not limit the number of hook-and-loop fasteners. The two parts of the second attachment portion (hook-and-loop fastener) 150 are respectively arranged at corresponding positions on the adjusting member 310 and the headrest 10.

[0195] The headrest 10 may include two pockets 120. The two pockets 120 may be arranged at positions corresponding to both ends of the adjusting member 310, so that both ends of the adjusting member 310 can be respectively inserted into the two pockets 120. The pocket 120 is, for example, a sheet covering the headrest 10, and a part of the outer periphery of the sheet (for example, for Figure 13 the left pocket 120 among them, it may be the upper side, the lower side and the left side) is attached to the headrest 10, while the remaining part of the outer periphery (for example, for Figure 13 the left pocket 120 among them, it may be the right side) is not attached to the headrest 10 so as to form an opening. For the convenience of inserting the adjusting member 310 into the pocket 120, the adjusting member may be bendable.

[0196] When both ends of the adjusting member 310 are respectively inserted into the two pockets 120, the two second attachment portions 150 may be located in the two pockets 120, thereby ensuring that the adjusting member 310 is stably fixed to the headrest 10.

[0197] Although Figure 13 only one adjusting belt 410 is shown, this embodiment may have two adjusting belts 410 arranged side by side and symmetrically. Figure 13 The two ends of the adjusting member 310 in Figure 13The second attachment portion 150 in [description] is shown as a dashed line, indicating that the second attachment portion 150 is disposed on the side of the adjuster 310 facing the headrest 10 and is thus blocked by the adjuster 310 and the pocket 120.

[0198] In this embodiment, buttons may not be provided. Other parts of this embodiment can be referred to the seventh embodiment.

[0199] In this embodiment, through the fixing force of the hook-and-loop fastener and the restraint of the pocket 120 on the adjuster 310, while the adjuster 310 is separable from the headrest 10, it can also form a stable and reliable connection with the headrest 10 and prevent the headrest 10 from shaking, which is convenient to operate.

[0200] The tenth embodiment of the present application will be described below. The tenth embodiment is similar to the seventh embodiment, and only the different parts will be described below.

[0201] See Figure 14 , in this embodiment, the adjuster 310 may be formed as one, but the present application is not limited thereto. The adjuster 310 may be formed as a rectangle (i.e., having a uniform width), but the present application is not limited thereto. Both ends of the adjuster 310 are detachably connected to the headrest 10 through the first attachment portion 140. The first attachment portion 140 may be a button. One button may be provided at each end of the adjuster 310, but the present application does not limit the number of buttons. The two parts of the first attachment portion (button) 140 are respectively disposed at corresponding positions on the adjuster 310 and the headrest 10.

[0202] The headrest 10 may include two pockets 120. The two pockets 120 may be disposed at positions corresponding to both ends of the adjuster 310 such that both ends of the adjuster 310 can be respectively inserted into the two pockets 120. The pocket 120 is, for example, a sheet covering the headrest 10, and a part of the outer periphery of the sheet (for example, for Figure 14 the left pocket 120 in [description] may be the upper side, the lower side, and the left side) is attached to the headrest 10, while the remaining part of the outer periphery (for example, for Figure 14 the left pocket 120 in [description] may be the right side) is not attached to the headrest 10 and thus an opening can be formed. For facilitating the insertion of the adjuster 310 into the pocket 120, the adjuster may be bendable.

[0203] When both ends of the adjuster 310 are respectively inserted into the two pockets 120, the two first attachment portions 140 may be located within the two pockets 120, thereby ensuring the stable fixation of the adjuster 310 to the headrest 10.

[0204] A second attachment portion 150 may also be provided in the middle of the adjuster 310, but the present application does not limit the number of the second attachment portions 150. The second attachment portion 150 may be a hook-and-loop fastener.

[0205] AlthoughFigure 14 Only one adjustment strap 410 is shown, but this embodiment may have two adjustment straps 410 arranged side by side and symmetrically. Figure 14 Both ends of the adjuster 310 in are shown as dashed lines, which means that both ends of the adjuster 310 extend into the pocket 120. Figure 14 The first attachment portion 140 in is shown as a dashed line, which means that the first attachment portion 140 is provided on the side of the adjuster 310 facing the headrest 10 and is thus blocked by the adjuster 310 and the pocket 120. Figure 14 The second attachment portion 150 in is shown as a dashed line, which means that the second attachment portion 150 is provided on the side of the adjuster 310 facing the headrest 10 and is thus blocked by the adjuster 310.

[0206] For other parts of this embodiment, reference can be made to the seventh embodiment.

[0207] In this embodiment, through the fixing force of the hook-and-loop fastener and the button and the restraint of the pocket 120 on the adjuster 310, while the adjuster 310 can be separated from the headrest 10, it can also form a stable and reliable connection with the headrest 10 and prevent the headrest 10 from shaking.

[0208] The eleventh embodiment of the present application will be described below.

[0209] See Figure 15 and Figure 16 In this embodiment, the infant carrier 1 may include a headrest 10 and a backrest 50. An adjustment strap 410 may be fixedly provided on the backrest 50. Both ends of the adjustment strap 410 may be fixed to the backrest 50, while other parts of the adjustment strap 410 may be separated from the backrest 50. The adjustment strap 410 may be flexible.

[0210] Optionally, two adjustment straps 410 may be arranged side by side on the backrest 50. Optionally, the two adjustment straps 410 are parallel to each other and oriented substantially vertically, and there is a certain distance between the two adjustment straps 410. The adjustment strap 410 may be a woven strap, but the present application is not limited thereto.

[0211] An adjuster 430 may be slidably provided on the adjustment strap 410. The adjuster 430 may be formed as a sheet, but the present application is not limited thereto. The adjuster 430 may include a connecting portion 432 and a positioning portion 433 connected to the connecting portion 432. At least two adjustment holes 431 may be provided in the positioning portion 433.

[0212] Optionally, the adjusting member 430 includes a connecting portion 432 and two positioning portions 433 located on both sides of the connecting portion 432. The two adjusting straps 410 can be respectively connected to the two positioning portions 433. Specifically, each adjusting strap 410 can sequentially pass through two or more adjusting holes 431 on the corresponding positioning portion 433. Each adjusting hole 431 exerts a certain resistance on the adjusting strap 410 passing through it, which enables the adjusting member 430 to be statically held at multiple specific positions on the adjusting strap 410. At the same time, since the size of the adjusting hole 431 is larger than that of the adjusting strap 410, the position of the adjusting member 430 relative to the adjusting strap 410 can be changed by moving the adjusting strap 410 relative to the adjusting hole 431. The adjusting member 430 can be integrally formed of plastic or resin to prevent the two positioning portions 433 from being asynchronous due to uneven force during the process of adjusting the height of the headrest 10, but the present application is not limited thereto.

[0213] See Figure 16 , a connecting strap 320 can be fixedly provided on the headrest 10. The connecting strap 320 can be flexible. One end (fixed end) of the connecting strap 320 can be fixed to the headrest 10, and the other end (free end) of the connecting strap 320 can be detachably connected to the headrest 10, and the other parts of the connecting strap 320 can be separated from the headrest 10. The free end of the connecting strap 320 can be detachably attached to the headrest in one way of a hook-and-loop fastener, a button, and a buckle, but the present application is not limited thereto. Specifically, the free end of the connecting strap 320 can form a first fixing portion 321, a second fixing portion 350 can be formed on the headrest 10, and the first fixing portion 321 can be connected to the second fixing portion 350. The second fixing portion 350 can be located above the fixed end of the connecting strap 320, but the present application is not limited thereto. The number of the connecting straps 320 can be less than the number of the adjusting straps 410. For example, one connecting strap 320 can be provided on the headrest 10, and two adjusting straps 410 can be provided on the backrest 50, thereby facilitating the quick detachment of the headrest 10 from the backrest 20 while ensuring the stable up-and-down sliding of the headrest 10.

[0214] A turning member 360 can be provided on the headrest 10. Both ends of the turning member 360 can be fixed to the headrest 10, so that a channel for the connecting strap 320 to pass through is formed between the turning member 360 and the headrest 10. The turning member 360 can be a flexible belt or a flexible rope, but the present application is not limited thereto. By providing the turning member 360, it can be prevented that during the process of moving the headrest 10, the adjusting member 430 directly contacts the attachment point of the free end of the connecting strap 320, resulting in the disconnection of the free end from the headrest portion 10.

[0215] See Figures 15 - 17, First, the free end of the connecting strap 320 on the headrest 10 passes through the channel formed between the connecting portion 432 of the adjusting member 430 and the backrest 50. Then, the free end of the connecting strap 320 passes through the channel formed between the deflecting member 360 and the headrest 10. Next, the free end of the connecting strap 320 passes through the channel formed between the connecting portion 432 of the adjusting member 430 and the backrest 50 again in the opposite direction. Finally, the free end of the connecting strap 320 is detachably connected to the headrest 10 (i.e., the first fixing portion 321 is detachably connected to the second fixing portion 350). Since the headrest 10 and the adjusting piece 430 are detachable, the headrest 10 may not contain hard materials such as plastics, which is convenient for washing and drying in a washing machine.

[0216] The upper edge of the headrest 10 may be formed as an inclined surface, so as to form a gap for holding the headrest 10 between the headrest 10 and the backrest 50. The free end of the connecting strap 320 is detachably attached to the upper edge of the headrest 10, so as to facilitate the detachment of the connecting strap 320.

[0217] In this embodiment, the adjusting strap 410 may be referred to as the first connecting member, and the adjusting member 430 may be referred to as the second connecting member.

[0218] In this embodiment, the headrest 10 can be adjusted in height relative to the backrest 50 of the infant carrier 1 to adapt to infants or children of different heights. The headrest 10 can be detached from the backrest 50 for easy cleaning.

[0219] The twelfth embodiment of the present application will be described below. It should be noted that the same parts of the twelfth embodiment and the eleventh embodiment will not be described again.

[0220] See Figure 18 , a connecting ring 440 may be formed on the backrest 50. The connecting ring 440 may be a flexible belt or a flexible rope, such as a webbing, but the present application is not limited thereto. Four connecting rings 440 may be formed on the backrest 50, but the present application is not limited thereto. Optionally, other numbers of connecting rings 440 may be formed on the backrest 50, for example, two connecting rings 440.

[0221] See Figure 19 , an adjusting member 430 may be provided on the headrest 10. The structure of the adjusting member 430 may refer to the description in the eleventh embodiment. The connecting portion 432 of the adjusting member 430 may be fixed to the headrest 10. Specifically, the connecting portion 432 of the adjusting member 430 may be sewn to the headrest 10. The adjusting strap 410 may sequentially pass through two or more adjusting holes 431 on the adjusting member 430. The positioning portion 433 of the adjusting member 430 may pivot or bend relative to the connecting portion 432 to facilitate the adjusting strap 410 to pass through the adjusting holes 431.

[0222] Both ends of the adjustment strap 410 may be respectively provided with connecting members 450. The connecting members 450 may be formed in a shape similar to the letter "C" or "G". The connecting members 450 may include a first arm 451 and a second arm 452. A notch 453 may be formed between the first arm 451 and the second arm 452. The notch 453 can be controlled to open or close, or the notch 453 can be made smaller to prevent the adjustment strap 410 from disengaging from the notch 453. Additionally, stop ribs may be designed at the ends near the notch of the first arm 451 and the second arm 452 to prevent the adjustment strap 410 from disengaging from the notch 453. The stop ribs protrude from the first arm 451 and the second arm 452, and the thickness of the stop ribs is greater than the thickness of the adjustment strap. The end of the adjustment strap 410 may pass through the notch 453 and be sleeved on one of the first arm 451 and the second arm 452. The other of the first arm 451 and the second arm 452 may pass through the connecting ring 440 and thus be detachably connected to the backrest 50.

[0223] See Figure 20 , the adjustment strap 410 is respectively connected to the two connecting rings 440 via the connecting members 450 at both ends, and the middle part of the adjustment strap 410 passes through the adjustment hole 431 of the adjuster 430. In this way, the headrest 10 is detachably connected to the backrest 50. Moreover, by moving the position of the adjustment strap 410 relative to the adjuster 430, the position of the headrest 10 relative to the backrest 50 can be adjusted.

[0224] The thirteenth embodiment of the present application will be described below. It should be noted that the parts that are the same as those in the eleventh embodiment will not be described again.

[0225] See Figure 21 , the difference between this embodiment and the eleventh embodiment is that one end of each adjustment strap 410 in this embodiment is provided with a connecting member 450, and a connecting ring 440 corresponding to the connecting member 450 is provided on the backrest 50, so that one end of the adjustment strap 410 is detachably connected to the backrest 50. In this embodiment, the adjuster 430 can be separated from the headrest 10 and the backrest 50, so that the adjuster 430 can be detachably removed when cleaning the headrest 10 and the backrest 50.

[0226] In some small seat cushion products known to the inventor, the headrest part and the small seat cushion are connected in a relatively fixed position, for example, they are integrated, or separable snap buttons or Velcro are used. In this way, the height position of the headrest part cannot be adjusted according to the height of the child's head, resulting in inconvenience in use. Additionally, there are some small seat cushions used in baby or child carriers that are equipped with an adjustable headrest part, but the headrest part and the small seat cushion are respectively connected to the seat. Therefore, when disassembly and cleaning are required, it is necessary to first separately disassemble the small seat cushion and then disassemble the headrest part connected to the seat, which also causes inconvenience in use.

[0227] The present application provides a seat cushion (or may be referred to as a "small seat cushion") for use by infants or children. The seat cushion can be detachably connected to an infant or child carrier such as a child safety seat, a baby stroller, a baby cradle, a baby carrier, or a baby cot, and can be used as part of the carrier. The seat cushion includes a seat cushion body (or main body) and a headrest portion connected to the seat cushion body. The seat cushion can be mainly made of a flexible material and has a shape adapted to the carrier to which it is applied. Additionally, the seat cushion according to the present application can adjust the position of the headrest portion relative to the seat cushion body according to actual needs, so as to adapt to children of different body lengths. This position adjustment can be achieved through a positioning structure between the seat cushion body and the headrest portion, and this positioning structure can also serve as the connection structure between the seat cushion body and the headrest portion.

[0228] Figures 22 - 25 FIG. shows a schematic view of a seat cushion 100S according to a first embodiment of the present application. Among them, Figure 22 is a front view schematic of the seat cushion of this embodiment when the headrest portion is in the lowest position (or "first position") relative to the seat cushion portion, Figure 23 is Figure 22 a rear view schematic of the seat cushion in the state of Figure 24 is a front view schematic of the seat cushion of this embodiment when the headrest portion is in the second position (or "second position") relative to the seat cushion portion, Figure 25 is Figure 24 a rear view schematic of the seat cushion in the state of

[0229] First, referring to Figure 22 and Figure 23 , the seat cushion 100S includes a seat cushion body 110S and a headrest portion 120S provided on its upper part, and the headrest portion 120S is in the lowest position (i.e., the first position) relative to the seat cushion body 110S. In this position, the bottom of the headrest portion 120S is closely attached to the upper side of the seat cushion body 110S. As can be seen from the figure, both sides of the upper part of the seat cushion body 110S may include a pair of shoulder side pads 112S, which can be padded on both sides of the shoulders of the occupant during use, and headrest side pads 122S are provided on both sides of the headrest portion 120S, which can be padded on both sides of the head of the occupant during use. As described above, according to the present application, the seat cushion body 110S and the headrest portion 120S are connected to each other through the positioning structure therebetween to form the integral seat cushion 100S. In Figure 22 and Figure 23 's state, this positioning structure is inside the headrest portion 120S and is not visible, and this positioning structure will be described in detail later.

[0230] In the seat cushion 100S according to this embodiment, the headrest portion 120S can be positionally adjusted and positioned within a certain range relative to the seat cushion body 110S by means of the above-mentioned positioning portion. Referring to Figure 24 and Figure 25, which shows the state when the headrest portion 120S of the seat cushion 100S is raised and positioned at a highest position (i.e., the second position). In combination with Figure 22 and Figure 24 it can be seen that according to this embodiment, when the headrest portion 120S is raised relative to the seat cushion body 110S, a seat cushion body neck portion 111S protruding from the end of the seat cushion body 110S can be seen below the headrest portion 120S, and the seat cushion body neck portion 111S extends into the interior of the headrest portion 120S from the bottom opening 123S (see Figure 25 ) of the headrest portion 120S. When the headrest portion 120S reaches the second position (see Figure 24 ), which is the maximum limit position to which the headrest portion 120S can be adjusted, at this time, the upper part of the seat cushion body neck portion 111S is still inside the headrest portion 120S, and a part of the sliding adjustment belt 130S arranged vertically can be seen at the seat cushion body neck portion 111S, and the sliding adjustment belt 130S is a part of the positioning structure of the seat cushion 100S of the present application. Therefore, during the use of the seat cushion 100S in the first embodiment of the present application, a part of the seat cushion body neck portion 111S and a part of the sliding adjustment belt 130S thereon will always be located inside the headrest portion 120S.

[0231] According to this embodiment, the sliding adjustment belt 130S is operably connected to a connecting member provided inside the headrest portion 120S, the connecting member is another part of the positioning structure, and the connecting member cooperates with the sliding adjustment belt 130S to realize the position adjustment of the headrest portion 120S. Figure 24 It can also be seen in Figure 27 that the sliding adjustment belt 130S has a plurality of convex line structures 132S arranged horizontally to assist in the vertical positioning of the headrest portion 120S. The structure of the sliding adjustment belt 130S is elaborated in detail in Figure 35 .

[0232] In addition, according to this embodiment, the top of the seat cushion body neck portion 111S has a lifting belt 118S, and the lifting belt has a predetermined length, so that when the headrest portion 120S is in the first position, the lifting belt 118S can be exposed at the top of the seat cushion 100S, as shown in Figure 22 . Specifically, at this time, the lifting belt 118S can pass through the inside of the headrest portion 120S and extend out through its top opening 121S. The lifting belt 118S is mainly used to lift the seat cushion body neck portion 111S upward to keep it upright, so as to facilitate the downward movement of the headrest portion 120S. In addition, the lifting belt 118S can also facilitate the taking and hanging of the seat cushion 100S. When the headrest portion 120S is in the second position, the lifting belt 118S can be retracted into the headrest portion without being exposed, as shown in Figure 24 and Figure 25As shown, at this time, the user can insert their hand through the top opening 121S of the headrest 120S to hold and pull up the lifting strap 118S, so as to adjust the headrest 120S downward. However, the present application is not limited thereto. For example, in Figure 26 In the second embodiment of the present application shown, the lifting strap 118S has sufficient length such that even when the headrest 120S is in the second position, the lifting strap 118S can still extend out through the top opening 121S of the headrest. Except for the difference in the lifting strap 118S, the seat cushion of this embodiment is no different from the aforementioned first embodiment. In Figure 26 The intermediate position between the first position and the second position of the headrest 120S of this embodiment is shown by a solid line, while the dotted line indicates that the headrest 120S is in the second position. It can be seen from this that during the use of the seat cushion 100S of this embodiment, the lifting strap 118S will always be exposed on the top of the seat cushion 100S, which can prevent the lifting strap 118S from being wound during the movement and adjustment of the headrest 120S, and the top opening 121S of the headrest 120S has the function of maintaining the position and orientation of the lifting strap 118S during this process. In addition, in Figure 26 The two opposite movement and adjustment directions of the headrest 120S are shown by double arrows. In other embodiments of the present application, for example Figures 37 - 40 The seat cushion of the shown embodiment does not have this lifting strap, and these embodiments will be specifically described later.

[0233] In Figure 23 and Figure 25 It can also be seen that the rear side of the headrest 120S of the seat cushion 100S according to the first embodiment has a flexible first back cover layer 124S and a second back cover layer 125S to cover the internal structure of the headrest 120S, which may include another part of the aforementioned positioning structure, and will be described in detail later in combination with Figures 33 - 35 this.

[0234] In addition, the seat cushion according to the present application can be connected to the vehicle through the belt components on the vehicle to which it is applied, and these belt components generally include shoulder straps and hip straps. For this purpose, the seat cushion body 110S in the seat cushion 100S according to the present application may include a shoulder strap through hole 114S and a hip strap through hole 116S (see Figure 24 and Figure 25 ), to cooperate with the shoulder strap and hip strap of the vehicle respectively, so as to connect the seat cushion as a whole to the vehicle. When it is necessary to disassemble, wash or replace the seat cushion 100S, the connection between these belt components and the seat cushion body 110S can be released, and the seat cushion including the seat cushion body 110S and the headrest 120S can be removed from the vehicle as a whole.

[0235] As described above, to achieve the adjustment and positioning of the headrest height in the seat cushion according to the present application, the seat cushion of the present application includes a positioning structure that is connected to both the seat cushion body and the headrest. The positioning structure may include a first positioning member and a second positioning member that cooperate with each other. The first positioning member may be provided on the seat cushion body, and the second positioning member may be provided on the headrest. The following will refer to Figures 27 - 36 describe this positioning structure in detail.

[0236] Figure 27 is a schematic front view of a separate seat cushion body according to the first embodiment of the present application; Figure 28 is a schematic rear view of a separate seat cushion body according to the first embodiment, in which the neck and adjacent parts of the seat cushion body are marked with a dashed circle; Figures 29 - 31 schematically shows three different embodiments of the neck of the seat cushion body including a neck reinforcement plate; Figure 32 is a schematic front view of a separate headrest according to an embodiment of the present application, Figure 33 is Figure 32 is a schematic rear perspective view of the headrest according to an embodiment of the present application; Figure 34 is a diagram showing the cooperation mode of the neck of the seat cushion body and the Figure 33 headrest according to an embodiment of the present application, in which the positioning structure located between the two is schematically shown in dashed lines, Figure 35 is a separate display of Figure 34 the cooperation relationship of the positioning structure shown; Figure 36 is a schematic diagram of the neck of the seat cushion body according to the sixth embodiment of the present application.

[0237] Refer to Figure 27 and Figure 28 and, in combination with reference to the foregoing Figures 24 - 26, according to the first and second embodiments of the present application, the first positioning member of the positioning structure is a sliding adjustment belt 130S provided on the neck 111S of the seat cushion body, which cooperates with the second positioning member (a connecting member in this embodiment) provided on the headrest portion 120S to form the positioning structure. The positioning of the headrest portion 120S can be achieved through the frictional force or limiting structure between the first positioning member and the second positioning member. The sliding adjustment belt 130S may include a pair of elongated sliding adjustment belts that are generally parallel and spaced apart by a predetermined distance. It is vertically provided on the front surface of the neck 111S of the seat cushion body, and each end 134S of the pair of sliding adjustment belts 130S is securely fixed to the neck 111S of the seat cushion body. The sliding adjustment belt 130S can be made of fabric or a plastic sheet having flexibility and surface roughness, and has a plurality of convex line structures 132S arranged at a predetermined pitch in the transverse direction to assist in positioning with the connecting member. However, the present application is not limited thereto. For example, the number of sliding adjustment belts 130S can also be one or more than three. The sliding adjustment belt 130S may not be provided with convex line structures, but other protrusion structures or transverse grooves may be provided to assist in positioning, or the friction force or adhesion with the connecting member can be improved by changing the surface characteristics of the material of the sliding adjustment belt 130S to improve the positioning performance.

[0238] As described above, the second positioning member of the positioning structure according to this embodiment is a connecting member 140S provided inside the headrest portion 120S. Refer to Figure 33 , the connecting member 140S is generally horizontally provided inside the headrest portion 120S, and includes a connecting portion 142S located in the middle and a pair of positioning portions 144S located on the left and right sides of the connecting portion 142S. The pair of positioning portions 144S are also spaced apart by the above-mentioned predetermined distance. The connecting member 140S includes at least two through holes for the corresponding sliding adjustment belts 130S to pass through. Specifically, each positioning portion 144S of the connecting member 140S includes at least one tube through hole, preferably including a pair of through holes, such as a "day" - shaped double - hole structure. The shape and arrangement of these engagement holes 146S are adapted to allow the aforementioned pair of sliding adjustment belts 130S to penetrate therein and slide freely. Refer to Figure 35Schematic diagram of the connection and cooperation between the sliding adjustment belt 130S and the connection member 140S shown in [the figure]. In addition, the connection member 140S can be integrally formed from a single plastic sheet, or the connection part 142S and the positioning part 144S made of plastic can be separately formed and connected into an integral connection member 140S by hot pressing or mechanical means. However, it should be noted that the implementation manner of the connection member in this application is not limited thereto. For example, a connection member including three or more positioning parts can be adopted, or the connection members themselves can be arranged in pairs. The positioning part is not limited to a double-hole structure, but can be formed by a pair of metal rings or ring parts made of other materials, or formed by other similar parts or structures that can be clamped to a certain extent at the convex lines, protrusions or grooves of the sliding adjustment belt, as long as it can ensure the slidable fit between the sliding adjustment belt and the connection member and maintain a certain degree of clamping effect at multiple positions.

[0239] More specifically, according to an embodiment of the present application, the connection member 140S can include a pair of positioning parts 144S arranged horizontally and spaced apart by a predetermined distance. The sliding adjustment belt 130S can include a pair of sliding adjustment belts 130S arranged in parallel and spaced apart by a predetermined distance. Each sliding adjustment belt 130S can include two end parts 134S fixed to one of the seat cushion body 110S or the headrest part 120S and a suspended section between the two end parts 134S. Each positioning part 144S is fixed in the other of the seat cushion body 110S or the headrest part 120S, and the suspended sections of the pair of sliding adjustment belts 130S are respectively passed through the corresponding one of the pair of positioning parts 144S.

[0240] In addition, the connection member 140S is fixed to the headrest part 120S through the connection part 142S, and a pair of positioning parts 144S including two engagement holes 146S are arranged in a cantilever shape on both sides of the connection part 142S (that is, the positioning part 144S is a free end movable relative to the connection part 142S). The connection part 142S can be fixed to the inner side of the headrest part 120S by mechanical connection or sewing, and a square connection part fixing line 148S can be formed, as Figure 33 and Figure 35 shown. The two positioning parts 144S can pivot around the connection part fixing line 148S (sewing line) on one side relative to the connection part 142S, which can facilitate the threading of the sliding adjustment belt 130S during the production and assembly process. However, this application is not limited thereto. The two ends of the connection member 140S (that is, the free ends of the two positioning parts 144S) can also be fixed to the headrest part together with the connection part 142S instead of being formed in a suspended state; as long as the aforementioned slidable fit between the positioning part 144S and the sliding adjustment belt 130S can be ensured.

[0241] It should be understood here that, as described above, Figure 27 andFigure 28 shows a separate seat cushion body 110S according to this embodiment, on which only a sliding adjustment belt 130S is provided; and Figure 32 and Figure 33 shows a separate headrest part 120S according to this embodiment, in which only a separate connecting member 140S is provided. However, in an actual product, the sliding adjustment belt 130S and the connecting member 140S are cooperated and connected together, as shown in Figure 34 and Figure 35 . Moreover, the cooperation and connection between the sliding adjustment belt 130S and the connecting member 140S in the seat cushion 100S need to be completed in the processing and assembly stage of the seat cushion product. For example, the sliding adjustment belt 130S needs to be inserted into the positioning part 144S of the connecting member before being fixed to the seat cushion body neck 111S of the seat cushion body 110S. Therefore, the split forms of the two parts of the seat cushion in the foregoing Figure 27 , Figure 28 , Figure 32 , Figure 33 are only schematic diagrams for convenient description, and such split forms do not exist in reality.

[0242] In addition, although the seat cushion body 110S and the headrest part 120S of the seat cushion 100S according to this embodiment are connected together through a positioning structure including the sliding adjustment belt 130S and the connecting member 140S, this does not mean that the seat cushion body 110S and the headrest part 120S must be inseparable. For example, the sliding adjustment belt 130S can be reliably fixed to the neck of the seat cushion body by a separable snap device, so that the headrest part 120S together with the sliding adjustment belt 130S can be removed from the seat cushion body 110S when necessary.

[0243] According to the present application, in order to more smoothly perform the up and down sliding adjustment and positioning of the headrest part in the seat cushion 100S without being hindered by the bending or folding of the seat cushion body neck 111S, a neck reinforcement plate 113S can be provided on the back side or inside of the seat cushion body neck 111S to improve the stiffness of this part. The neck reinforcement plate 113S can be formed by a plastic sheet or other rigid sheet. Referring to Figure 29 , Figure 30 and Figure 31 , they respectively show three embodiments including the neck reinforcement plate 113S on the back of the seat cushion body neck 111S. Among them, Figure 29 shows the third embodiment of the present application, and the main difference from the first embodiment is that a neck reinforcement plate 113S is provided on the back of the seat cushion body neck 111S and the upper side of the shoulder strap passing hole 114S. Figure 30The fourth embodiment of the present application is shown. The difference from the third embodiment is that the neck reinforcement plate 113S and the lifting strap 118S are integrated, so that during the process of sliding adjustment of the headrest relative to the seat cushion body, the lifting strap and the neck are not easily bent or wound. At this time, the lifting strap 118S and the neck reinforcement plate 113S can be made of the same rigid material. In other embodiments, the lifting strap 118S can be made of a rigid material, but can also be made of a flexible material with a certain toughness. Figure 31 The fifth embodiment of the present application is shown. The difference from the third embodiment is that the area of the neck reinforcement plate 113S is extended to include the shoulder strap through-hole 114S. Therefore, the neck reinforcement plate 113S includes a shoulder strap groove, which strengthens the area of the shoulder strap through-hole 114S together with the neck 111S of the seat cushion body. In addition, in this embodiment, since the area of the neck reinforcement plate 113S extends downward, the lifting strap 118S is not provided at the top of the neck 111S of the seat cushion body. However, the present application is not limited thereto.

[0244] Returning to Figure 33 and Figure 34 , and with reference to Figure 23 and Figure 25 , the back structure of the headrest according to the foregoing embodiments will be further described. In Figure 33 and Figure 34 , the first back cover layer 124S and the second back cover layer 125S on the rear side of the headrest 120S are in an open or semi-open state. In Figure 33 , the connecting member 140S located on the inner surface of the front side of the headrest 120S can be seen. The connecting member 140S can be provided on the inner surface of a recess 128S inside the headrest 120S. The recess 128S of the headrest 120S is adapted to accommodate the corresponding neck 111S of the seat cushion body, and a reinforcing layer can be provided on the inner surface of the recess 128S to improve the connection strength between the connecting member 140S and the inside of the headrest. Due to the presence of the recess 128S of the headrest 120S, during the process of moving and adjusting the position of the headrest 120S, the overlapping part of the headrest 120S and the neck 111S of the seat cushion body will not bulge, which can improve the comfort of the baby or child when using the seat 100S. In actual use, the first back cover layer 124S and the second back cover layer 126S can be overlapped around the headrest from both sides, and the first hook-and-loop part 126S on the first back cover layer 124S and the second hook-and-loop part 127S on the second back cover layer 125S are fixed to each other, covering the neck 111S of the seat cushion body in the recess 128S inside the headrest 120S, as Figure 34As shown, the headrest portion 120S can be connected and sleeved on the neck portion 111S of the seat cushion body. This structure can enhance the connection stability between the headrest portion 120S and the seat cushion body 110S. In addition, the top opening 121S and the bottom opening 123S of the headrest portion 120S can be respectively formed between the top edge and the bottom edge on the inner side of the headrest portion 120S and the back claddings 124S, 125S, and the size of the bottom opening 123S is larger than the size of the top opening 121S. However, the headrest portion of the present application is not limited to the above structure, and the first back cladding and the second back cladding can also be combined with each other through structures such as zippers, or the back of the headrest portion 120S only includes an integral outer cladding, which can be opened and fixed along the back edge of the headrest portion, and openings 121S, 123S can be specifically formed at the top and bottom of the headrest portion.

[0245] Figure 36 Fig. shows a front view of the neck portion 111S of the seat cushion body according to the sixth embodiment of the present application. The difference between this embodiment and the foregoing embodiments is that the connecting member of the positioning structure is provided on the neck portion 111S of the seat cushion body, rather than on the headrest portion 120S. Correspondingly, the sliding adjustment belt of the positioning structure according to this embodiment is provided inside the headrest portion 120S (not shown). In addition, the neck portion 111S of the seat cushion body in this embodiment can also be provided with a neck reinforcement plate (as shown in the dotted area in the figure) to improve the convenience of adjusting the position of the headrest portion.

[0246] Figure 37 Fig. shows a schematic front view of the headrest portion 120S according to the seventh embodiment of the present application. Figure 38 Fig. shows a schematic front view of the headrest portion 120S according to the eighth embodiment of the present application. Figure 39 Fig. is a schematic front view of the seat cushion body 110S according to the seventh and eighth embodiments. Figure 40 is Figure 39 schematic rear view of the seat cushion body 110S.

[0247] Referring to Figure 37 and Figure 38 The seventh and eighth embodiments of the present application are different from the foregoing first to sixth embodiments in that the lower part of the headrest portion 120S has a downwardly protruding headrest neck portion 129S. And, the headrest neck portion 129S according to the seventh embodiment is provided with a sliding adjustment belt 130S, while the headrest neck portion 129S according to the eighth embodiment is provided with a connecting member 140S. Correspondingly, please refer to Figure 39 and Figure 40, the upper part of the seat cushion body 110S according to the seventh and eighth embodiments does not have a neck, but has a recess adapted to receive the neck 129S of the headrest portion therein. The recess communicates with the outside through a seat cushion body opening 119S formed at the top of the seat cushion body 110S. The neck 129S of the headrest portion passes through the seat cushion body opening 119S and fits into the recess in the upper part of the seat cushion body 110S. Furthermore, a connecting member 140S is provided in the recess in the upper part of the seat cushion body 110S according to the seventh embodiment of the present application to connect with a sliding adjustment band 130S on the neck 129S of the headrest portion fitted in the recess; while a sliding adjustment band 130S is provided in the recess in the upper part of the seat cushion body 110S according to the eighth embodiment of the present application to connect with a connecting member 140S on the neck 129S of the headrest portion fitted in the recess. Similarly, in the seventh and eighth embodiments, the sliding adjustment band 130S and the connecting member 140S together constitute a positioning structure, and during the use of the seat cushion 100S, at least a part of the positioning structure will be received in the recess in the upper part of the seat cushion body 110S.

[0248] In addition, from Figure 39 and Figure 40 it can also be seen that there is no shoulder strap perforation 114S in the upper part of the seat cushion body 110S according to the seventh and eighth embodiments of the present application. In this case, when applying the seat cushion to the corresponding infant carrier, the shoulder straps of the carrier can directly pass through between the seat cushion body 110S and the headrest portion 120S and directly wrap around from both sides of the neck 129S of the headrest portion to connect the seat cushion with the carrier body. Of course, the present application is not limited thereto. In the above-mentioned seventh and eighth embodiments, a pair of shoulder strap perforations 114S can also be provided in the upper part of the seat cushion body 110S as in other embodiments for passing through the shoulder straps of the carrier.

[0249] In other embodiments according to the present application, the shoulder strap perforations 114S provided in the upper part of the seat cushion body 110S can also be omitted, and the seat cushion can be connected to the carrier body by directly passing the shoulder straps of the carrier through between the seat cushion body 110S and the headrest portion 120S. However, in any case, providing shoulder strap perforations 114S in the upper part of the seat cushion body 110S for the shoulder straps of the carrier to pass through is an optional way.

[0250] In addition, in Figure 37 and Figure 38 a reinforcing plate can also be provided on the back or inside of the neck 129S of the headrest portion to increase the stiffness of the neck 129S of the headrest portion, so as to facilitate the movement adjustment of the headrest portion relative to the seat cushion body.

[0251] Please return to refer to Figure 35The position adjustment and positioning of the headrest portion 120S of the seat cushion 100S according to the foregoing embodiments of the present application are achieved in the following manner: After the positioning structure between the seat cushion body 110S and the headrest portion 120S is assembled, the sliding adjustment belt 130S sequentially passes through the two engagement holes 146S of the positioning portion 144S, so that when an external force (such as a pulling force) acts on the headrest portion 120S, the sliding adjustment belt 130S can slide up and down in the engagement holes 146S of the positioning portion 144S, and when the external force is withdrawn, the two can be held in any relative position by means of the friction or adhesion between the sliding adjustment belt 130S and the positioning portion 144S, as well as the limiting structures such as the convex lines on the sliding adjustment belt.

[0252] According to the foregoing embodiments, the seat cushion of the present application has both a simple structure and can conveniently achieve continuous and reliable adjustment and positioning of the headrest on the seat cushion body.

[0253] On the other hand, the present application provides a baby carrier, including a carrier body and a seat cushion 100S according to any one of the foregoing embodiments of the present application. Figure 41 The baby carrier according to the present application is schematically shown, wherein the carrier body is a child safety seat 10S and includes, for example, a seat cushion 100S according to the first embodiment of the present application, and the headrest portion of the seat cushion is in the first position (or the lowest position). Figure 42 Schematically shown in Figure 41 the state where the headrest portion of the seat cushion 100S in the baby carrier is raised to the second position (or the highest position).

[0254] Referring to Figure 41 and Figure 42 , in the baby carrier 1S, the seat cushion 100S according to the first embodiment is connected to the child safety seat 10S, wherein the child safety seat 10S includes a seat portion 11S on the lower side and a backrest portion 12S integrally formed with the seat portion. A pair of shoulder straps 14S and a crotch strap 16S are respectively fixed on the backrest portion 12S and the seat portion 11S of the child safety seat 10S for connecting the seat cushion 100S to the child safety seat 10S through the seat cushion body 110S, and providing safety protection by restraining the shoulders and crotches of the child sitting on the seat cushion 100S during actual use. Specifically, one end of each shoulder strap 14S can be fixed to the backrest portion 12S, and the other end of each shoulder strap 14S can pass through a corresponding shoulder strap insertion hole 114S in the upper part of the seat cushion body 110S (see Figure 42)It is detachably engaged with an engagement buckle 18S provided at one end of the crotch strap 16S. The other end of the crotch strap 16S passes through a crotch strap through-hole 116S in the middle and lower part of the seat cushion body 110S and is fixed to the seat part 11S. The shoulder strap 14S and the crotch strap 16S can be reliably connected and easily separated through the engagement buckle 18S.
