Abstract
Description
[Technical Field]
[0001] The present disclosure relates to a headrest adjustment mechanism and a baby carrier including the headrest adjustment mechanism. [Background technology]
[0002] Baby carriers, such as baby carrycots, strollers, baby slings, baby seats, and car seats, provide convenience and safety for babies while traveling. A typical baby carrycot typically includes a seat body and a headrest. To accommodate babies of various sizes, the headrest is typically designed to be vertically adjustable along the backrest. However, most headrests designed for baby carrycots currently on the market have complex mechanical structures with multiple parts, making them inconvenient to use. Furthermore, the headrest adjustment mechanism can increase the weight of the carrier, making it difficult for caregivers to carry the baby carrycot. Summary of the Invention
[0003] The present disclosure provides a headrest adjustment mechanism for adjusting the position of a headrest relative to a seat support of a baby carrier. The headrest adjustment mechanism includes a headrest plate and an adjustment belt, the adjustment belt being provided with a seat support for connecting the headrest plate and the seat support, the headrest plate having an adjustment member configured to clamp the adjustment belt, and the adjustment member for adjusting the position of the headrest plate along the length of the adjustment belt. According to the present disclosure, the headrest is slidably connected to the seat and can be advantageously adjusted vertically up and down relative to the seat to accommodate babies of different heights.
[0004] According to the embodiment of the present disclosure, the headrest plate and the adjustment member are integrated, which reduces the number of mechanical structural pieces and simplifies the structure of the headrest adjustment mechanism.
[0005] According to an embodiment of the present disclosure, the adjustment member protrudes from the surface of the headrest plate in a direction facing the seat body, thereby reducing the contact area between the headrest plate and the seat body and reducing resistance when adjusting the headrest.
[0006] According to an embodiment of the present disclosure, the adjustment member has at least one first positioning arm and at least two second positioning arms spaced apart.
[0007] According to an embodiment of the present disclosure, the adjustment belt is flat and has a first surface and a second surface, the first surface abutting the first positioning arm of the adjustment member, and the second surface abutting the second positioning arm of the adjustment member. The flat adjustment belt allows for a more compact structure of the headrest adjustment mechanism and can be adapted to a seat-shaped headrest plate, improving ride comfort. The flat adjustment belt also increases the contact surface between the adjustment belt and the positioning arm, increasing friction.
[0008] According to an embodiment of the present disclosure, the first positioning arm and the second positioning arm are located on the same plane or on different planes. When the first positioning arm and the second positioning arm are located on the same plane, a raised portion can be formed on the portion of the adjustment belt that abuts against the first positioning arm to increase the pressure between the adjustment belt and the first and second positioning arms and increase friction. When the first positioning arm and the second positioning arm are located on different planes, the position of the through hole in the adjustment belt can be set arbitrarily.
[0009] According to an embodiment of the present disclosure, a resistance device is provided on the surface of at least one of the first positioning arm and the second positioning arm that contacts the adjustment belt to increase friction between the adjustment member and the adjustment belt.
[0010] According to an embodiment of the present disclosure, the resistance device is a tooth-shaped protrusion disposed on the surface of the adjustment member facing the adjustment belt, thereby increasing the friction between the adjustment member and the adjustment belt with a simple structure. The protrusion may be a tooth-like protrusion, an anti-skid rib, a rough surface, etc.
[0011] According to an embodiment of the present disclosure, the adjustable belt has a plurality of sew lines extending perpendicular to the length of the adjustable belt, and in this embodiment, a roughened portion is formed between the adjustment member and the adjustment belt by simple machining to facilitate holding the adjustment member in place near the sew lines.
[0012] According to an embodiment of the present disclosure, the adjustment member is configured to have two or more through holes, and the adjustment belt is configured to pass through the through holes. The adjustment member is provided with through holes that allow the adjustment belt to pass through, and the adjustment member cooperates with the adjustment belt through the through holes to adjustably fix the headrest plate at multiple consecutive positions in the vertical direction, accommodating babies of different heights and preventing the headrest from moving up and down freely during use.
[0013] According to an embodiment of the present disclosure, the headrest adjustment mechanism includes a fixing member provided on the seat body along the longitudinal direction of the seat body for fixing the adjustment belt to the seat body. By disposing the fixing member detachably from the seat body, different types of fixing members can be individually disposed according to different needs, such as different screw receiving portions and adjustment belt receiving portions, and the fixing member can be easily replaced to fit different seat bodies.
[0014] According to an embodiment of the present disclosure, the fixing member is configured to have a groove extending substantially along the longitudinal direction of the seat body, the groove having a bottom portion and side portions provided on both lateral sides of the bottom portion. According to this embodiment, the adjustment belt is embedded in the groove of the fixing member, and the fixing member is embedded in the backrest portion together with the adjustment belt, and is fixedly connected to the backrest portion or the seat body covered by the backrest portion via screws provided at connection portions on both ends. This results in a compact structure. Furthermore, by fitting the protruding adjustment member of the headrest plate into the groove, the gap between the headrest plate and the seat body can be reduced.
[0015] According to an embodiment of the present disclosure, the adjustment member has side wings located on both lateral sides, and the side wings are inserted into and matched with the side portions of the fixing member so that the headrest plate is slidably positioned relative to the seat body. The side wings protrude laterally from the adjustment belt and can be inserted into the corresponding guide grooves, so that the adjustment member can slide within the guide grooves and prevent the headrest plate from separating from the backrest.
[0016] According to an embodiment of the present disclosure, the adjustment member has a positioning member, which cooperates with a positioning portion on the groove to position the headrest plate.
[0017] According to an embodiment of the present disclosure, the positioning member is provided on the outer surface of the bottom side of the adjustment member facing the bottom of the groove. According to this embodiment, the positioning member is provided in the vertical direction on the outer peripheral surface of the bottom side of the adjustment member facing the bottom of the groove of the fixing member. When the convex portion or the positioning protrusion is provided in the vertical direction, the headrest height is adjusted by pulling the upper end of the headrest, and on the other hand, a vertical pulling force is applied to the headrest plate to prevent the headrest plate from separating from the seat main body. Therefore, the convex portion or the positioning protrusion provided on the surface of the adjustment member of the headrest plate at least partially disengages from the positioning recess of the fixing member, thereby reducing resistance when adjusting the headrest height. On the other hand, a vertical pulling force is applied to the headrest to adjust the headrest height along the length direction of the adjustment belt.
[0018] According to an embodiment of the present disclosure, the positioning member is provided on the outer surface of the side portion where the adjustment member faces the groove. According to this embodiment, the operation mode is simplified.
[0019] According to an embodiment of the present disclosure, the positioning portion is configured as a wave-shaped positioning portion, and the positioning member moves along the wave-shaped positioning portion to be positioned in the trough. The wave-shaped positioning portion allows the adjustment member to move and be positioned continuously, providing a user with an intuitive positioning sensation.
[0020] According to an embodiment of the present disclosure, the adjustment member is provided with an elastic arm, the elastic arm is deformable in a direction perpendicular to the longitudinal direction, and the positioning member is configured on the elastic arm, and the elastic arm can realize smooth movement and positioning of the adjustment member by its own deformation.
[0021] According to an embodiment of the present disclosure, the positioning member is configured on the side wing, thereby enabling lateral positioning with anti-drop features and guide features attached to the side wing.
[0022] According to an embodiment of the present disclosure, one of the positioning member and the positioning portion is configured as a plurality of protrusions, and the other of the positioning member and the positioning portion is configured as a plurality of recesses that match the protrusions.
[0023] According to an embodiment of the present disclosure, the adjustable belt has an upper end and a lower end along the longitudinal direction of the seat body, the upper end being fixed to the bottom side of the fixing member through a perforation in the upper part of the fixing member, and the lower end being fixed to the outer side of the fixing member through a perforation in the lower part of the fixing member. The fixing points of the upper and lower ends of the adjustable belt are not on the same plane as the longitudinal direction of the adjustable belt, which securely fixes the adjustable belt and prevents it from loosening.
[0024] According to an embodiment of the present disclosure, an anti-slip rib is provided on the surface of the headrest plate facing the seat body. The headrest plate is curved so that there is a gap between the anti-slip rib and the seat body. The anti-slip rib is used to increase friction between the hand and the headrest plate when the user grips this position to adjust the headrest height.
[0025] According to an embodiment of the present disclosure, the headrest plate has a sheet-like structure, and the headrest plate has a hollow portion, which can be aligned with the hollow portion of the backrest and the hollow portion of the seat body, thereby ensuring the passage of shoulder straps and / or ventilation of the backrest, and advantageously reducing the weight of the component.
[0026] According to an embodiment of the present disclosure, the adjustment belt is made of a flexible material, which generally has a large contact area and can advantageously improve the friction between the adjustment belt and the adjustment member.
[0027] According to an embodiment of the present disclosure, the adjustment belt is a woven tape, which has a rough surface and therefore can exert a greater friction force than a smooth surface.
[0028] The present disclosure provides a baby carrier including a seat body, a headrest, and the above-mentioned headrest adjustment mechanism, wherein the headrest adjustment mechanism is provided between the seat body and the headrest. The headrest adjustment mechanism of the present disclosure allows the headrest to be slidably connected to the seat and adjusted vertically relative to the seat, thereby accommodating babies of different heights.
[0029] According to an embodiment of the present disclosure, the baby carrier is a baby carrycot, a stroller, a baby seat, or a car safety seat.
[0030] The present disclosure provides a headrest plate for a baby carrier, the headrest plate having an adjustment member protruding from a surface of the headrest plate, the adjustment member being configured to have two or more through holes. [Brief explanation of the drawings]

[0033] The directions such as "front", "rear", "up", "down" and the like referred to in this specification are merely for the convenience of understanding, and the present disclosure is not limited thereto and can be adjusted according to actual circumstances. Although the present disclosure has been described with reference to exemplary embodiments, the terms used are exemplary and illustrative, not limiting.
[0034] Because the present disclosure may be embodied in various forms without departing from the spirit and essence of the present disclosure, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be interpreted as broadly as possible within the scope defined by the claims. Accordingly, all changes that come within the scope of the claims or their equivalents are intended to be covered by the claims.
[0035] 1 is a perspective view of a baby carrycot 1 according to one embodiment of the present disclosure. The baby carrycot 1 is a baby carrier 1, and may be a stroller, a baby seat, or a car safety seat. The baby carrycot 1 includes a seat 200, a handle 400 rotatably connected to the seat 200, and a headrest 300 slidably connected to the seat 200 and adjustable up and down along the longitudinal direction relative to the seat 200, to accommodate babies of different heights. The baby carrycot 1 further includes a headrest adjustment mechanism 100 to adjust the headrest 300.
[0036] The baby carrycot 1 is particularly designed for carrying a light baby. For this reason, the seat 200 is designed in a carrycot shape, allowing the baby to be semi-reclined within the baby carrycot 1 while seated. The seat 200 includes a seat body 210 having a folding structure (side view in FIG. 4) so that the baby can be stably placed in a semi-reclined position. The peripheral edge of the seat body 210 is integrally covered with a cover portion 230, which can be made of an appropriate cushioning material such as expanded polypropylene (EPP). In this embodiment, the lower portion of the seat body 210 not covered by the cover portion 230 can be used, for example, for inserting a safety belt and / or for installing a seat cushion that fits the baby's lower body, and the upper portion of the seat body 210 is provided with a backrest portion 220 that fits the baby's upper body. The backrest portion 220 can be made of a relatively soft material, optionally EPP or other appropriate material, to enhance comfort. According to this embodiment, side pads 240, which may be selected as side wing inactive foam, are provided on both sides of the seat 200, and the side pads 240 may be configured to cover the entire sides of the seat 200 to provide lateral protection for the baby's upper body, including the head. The handles 400 may be rotatably provided on both sides of the seat main body 210 or the cover portion 230, so that the handles 400 are essentially perpendicular to the seat 200 in the carried state, and can be rotatably positioned to overlap the seat 200 as shown in FIG. 1 in the uncarried state.
[0037] According to one or more embodiments of the present disclosure, the baby seat 1 includes a headrest adjustment mechanism 100 including a headrest plate 110 and an adjustment belt 120. The adjustment belt 120 is provided on the seat body 210 to connect the headrest plate 110 and the seat body 210, and is fixed to, for example, a backrest 220 of the seat body 210. The headrest plate 110 has an adjustment member 111 that is operable to clamp the adjustment belt 120 to adjust the position of the headrest plate 110 along the length of the adjustment belt 120. In some embodiments, the headrest plate 110 may optionally be a lightweight sheet-like structure, such as made of polypropylene (hereinafter referred to as PP). The adjustment belt 120 connects the headrest plate 110 to the backrest 220. In some embodiments, the adjustment belt 120 is made of a flat, belt-like, flexible material, such as a woven tape, to make the headrest adjustment mechanism 100 more compact. In another embodiment, the adjustment belt 120 may be an elastic rope having a circular cross section. Optionally, the surface of the fabric tape is provided with a plurality of stitching lines (not shown) extending generally along the length direction perpendicular to the fabric tape, thereby making it easier to position the adjustment member 111 on the stitching lines. In this embodiment, the adjustment belt 120 is configured to pass flat through the adjustment member 111 provided on the headrest plate 110 (as shown in FIGS. 5 and 6 ). The headrest plate 110 can move up and down in the backrest portion 220, particularly in the vertical direction of the backrest portion 220, via the adjustment belt 120. The headrest plate 110 is used to install and adjust the position of the headrest 300, particularly to adjust and position the relative vertical positions of the headrest 300 and the backrest portion 220 along the vertical direction of the backrest portion 220. The headrest 300 may be configured integrally with the headrest plate 110 or separately to provide some cushioning for the baby's head. In a one-piece configuration, for example, the headrest 300 can be provided with a removable soft sleeve on the outside, making it more comfortable and convenient to remove and wash.In the separate structure, the headrest 300 itself may be made of a soft material such as EPP and may be detachably connected to the headrest plate 110 via a headrest attachment device. In Fig. 1, the headrest 300, together with the headrest plate 110, is adjusted to a low position along the longitudinal direction of the backrest portion 220 to accommodate small babies.
[0038] 5 and 6, according to one embodiment, the headrest plate 110 is provided with an adjustment member 111 for clamping the adjustment belt 120 (described in detail later), and the adjustment member 111 is provided with a through-hole 112 or adjustment hole 112 for passing the adjustment belt 120 through, and the adjustment member 111 cooperates with the adjustment belt 120 via the through-hole 112 to adjustably fix the headrest plate 110 at a plurality of consecutive vertical positions to meet the needs of babies of different heights, and also prevents the headrest 300 from moving up and down during use. In FIG. 1, a plurality of hollow portions 114A and 114B may be shown, and the hollow portion 114A may be matched with a hollow portion 250 in the backrest portion 220 or the seat main body 210 to allow the passage of shoulder straps of a baby carrycot and advantageously reduce the weight of the component. In some embodiments, when the headrest plate 110 is adjusted to any vertical position, at least a portion of the hollow portion 114A overlaps with the hollow portion 250 of the seat body 210, so as not to affect the passage of the carrycot shoulder straps regardless of the height of the headrest. In particular, the hollow portion 114B is provided for fixing the headrest adjustment mechanism 100 (described in more detail below).
[0039] Figure 2 is a perspective view of a baby carrycot 1 according to an embodiment of the present disclosure. Compared to Figure 1, the headrest plate 110, together with the headrest 300, is adjusted to a vertically intermediate position to accommodate babies of average height. The hollow portion 114A of the headrest plate 110 is moved vertically upward, completely exposing the hollow portion 250. The baby carrycot 1 shown in Figure 2 does not have a fabric cover, exposing the fixing member 130 on the underside of the headrest plate 110, and exposing the screw 137A of the fixing member 130 used to connect the headrest plate 110 to the backrest portion 220 in the hollow portion 114B.
[0040] Figure 3 is a perspective view of a baby carrycot 1 according to an embodiment of the present disclosure. Compared to Figure 2, the headrest is adjusted to a vertically higher position to accommodate a taller baby. The hollow portion 250 is further positioned below the hollow portion 114A of the headrest plate 110. The fixing member 130 is more exposed below the headrest plate 110. Note that because the baby carrycot 1 shown in Figure 3 is not covered with a fabric cover, the lower screw 137B for fixing the fixing member 130 to the backrest portion 220 and the upper screw 137A are both visible.
[0041] Figure 4 is a cross-sectional side view taken along line II in Figure 3. In Figure 4, it can be seen that the bottom of the seat body 210 of the baby carrycot 1 is configured in an arc shape, allowing the baby carrycot 1 to be used as a cradle when placed on the ground. The baby can be carried when the baby is in a semi-reclined position in the baby carrycot 1 and the handle 400 is rotated so that it is substantially perpendicular to the seat body 210. The headrest adjustment mechanism 100 of the present disclosure can be used to adjust the vertical position of the headrest 300 relative to the backrest portion 220 of the seat 200. This not only has a simple structure and easy operation, but also reduces the weight of the baby carrycot 1.
[0042] 5 is an enlarged view of a portion A of the headrest adjustment mechanism 100 at the fixing member 130 in FIG. 4. The adjustment belt 120 is fixed to the fixing member 130, and the headrest plate 110 is adjustably fixed to the seat main body 210. The fixing member 130 equipped with the adjustment belt 120 is embedded in the seat main body 210 and fixedly connected to the seat main body 210 or the backrest portion 220 that covers the seat main body 210 via screws 137A and 137B provided at connection portions 133 at both ends. The adjustment belt 120 has an upper end that passes through an upper perforation 135 of the fixing member 130, enters the back side of the fixing member 130, makes two turns around the fixing member 130, and is then folded and fixed to the bottom side of the fixing member 130 with a screw 137C, and a lower end that passes through two lower perforations 135 in succession and is fixed to the lower connection portion 133 with a screw 137B. The fixed embodiment of the adjustment belt 120 is useful for adjusting the stress of the adjustment belt 120, for example, for stretching the adjustment belt 120. Furthermore, the connection portion 133 of the fixing member 130 is configured to be angled with respect to the backrest portion 220 or the seat main body 210 and the bottom 131 of the fixing member 130 in order to fit the internal structure of the backrest portion 220 or the seat main body 210. Furthermore, the connection portion 133 of the fixing member 130 is angled with the bottom 131 of the fixing member 130 to form receiving portions for the screws 137A and 137B, thereby advantageously saving space and simplifying installation.
[0043] In this embodiment, the protrusions 122 of the adjustment belt 120 are particularly visible. The headrest plate 110 includes an adjustment member 111 that clamps the adjustment belt 120, and the adjustment belt 120 applies pressure and vertical friction to the adjustment member 111 to bring the headrest plate 110 close to the seat main body 210. This allows the headrest plate 110 to move freely along the length of the adjustment belt 120 when pulled / pushed by the user, and to remain in its current position when the user stops pulling / pushing. The headrest plate 110 may be integrated with the adjustment member 111 to simplify the structure. In one or more embodiments, the adjustment member 111 protrudes from the surface of the headrest plate 110 in a direction facing the seat main body 210.
[0044] The adjustment member 111 includes at least one first positioning arm 111a and at least two second positioning arms 111b spaced apart. According to this embodiment, the adjustment belt 120 is flat and has a first surface abutting the first positioning arm 111a of the adjustment member 111 and a second surface abutting the second positioning arm 111b of the adjustment member 111. The first positioning arm 111a and the second positioning arm 111b are perpendicular to the length direction of the adjustment belt 120, and the first positioning arm 111a and the second positioning arm 111b may be on the same plane or on different planes. An adjustment hole 112 is formed on the bottom surface of the adjustment member 111 via the first positioning arm 111a and the second positioning arm 111b. Here, two parallel through-holes 112 form a square-shaped adjustment hole (i.e., a rectangle with one short horizontal line inserted through its center), and the flat adjustment belt 120 passes through the two parallel through-holes in sequence to form the raised portion 122. Note that if the first positioning arm 111a and the second positioning arm 111b are on different planes, the through-hole 112 may also be formed in the side wall of the adjustment member 111. For example, one through-hole 112 may be provided on the bottom side and the other through-hole 112 may be provided on the side wall; this disclosure is not limited to this. Also, according to the present disclosure, the adjustment member 111 serves to clamp the adjustment belt 120, but the specific form of the adjustment member 111 is not limited to the square-shaped adjustment hole 112; for example, it may be a square-shaped adjustment hole (i.e., a rectangle with two short horizontal lines inserted through it) or an open E-shaped adjustment hole 112.
[0045] According to this embodiment, the headrest plate 110 is connected to the backrest 220 by the adjustment belt 120 passing through the two through holes 112. Meanwhile, to adjust the position of the headrest 300 relative to the backrest 220, the headrest plate 110 can be pulled along the longitudinal direction of the backrest 220, causing the adjustment member 111 having the square-shaped adjustment holes 112 to move along the adjustment belt 120. As the adjustment belt 120 pulls the headrest plate 110 relative to the backrest 220, the friction between the adjustment belt 120 and the adjustment member 111 prevents the headrest plate 110 from moving relative to the backrest 220 in the inoperative state. To increase the friction, tooth-like protrusions 118 may be provided on the hole wall of the through hole 112 on one side of the adjustment member 111, as shown in FIG. 6 . Furthermore, to increase the friction between the adjustment member 111 and the adjustment belt 120, a resistance device may be formed on the surface of at least one of the first positioning arm 111a and the second positioning arm 111b that contacts the adjustment belt 120. For example, the first positioning arm 111a of the square-shaped through-hole 112 that forms the protrusion 122 may be provided with a roughened portion that faces the adjustment belt 120. To increase the friction force, the resistance device may be a protrusion or a roughened portion, such as a sewing thread, provided on the adjustment belt 120.
[0046] FIG. 6 is a front view of the headrest plate 110 of the headrest adjustment mechanism 100 according to an embodiment of the present disclosure. In this embodiment, the headrest plate 110 further includes, in addition to the hollow portions 114A and 114B, a headrest attachment (such as the headrest attachment portion 117) for connecting the headrest 300. In this embodiment, the adjustment belt 120 is detached from the adjustment member 111, so that the adjustment member 111 not covered by the adjustment belt 120 can be seen. The adjustment member 111 includes at least one first positioning arm 111a and at least two second positioning arms 111b spaced apart from each other. According to this embodiment, the adjustment member 111 is configured with two through holes through which the adjustment belt 120 can pass via the at least one first positioning arm 111a and at least two second positioning arms 111b. In this embodiment, the adjustment member 111 is configured as two parallel horizontal slots, forming a square-shaped adjustment member 111. In this embodiment, a resistance device 118 is provided on the hole wall of the adjustment member 111 to advantageously increase the friction between the adjustment belt 120 and the adjustment member 111. The resistance device 118 may be provided as a protrusion 118, or as an anti-slip structure, anti-slip rib, tooth, rough surface, etc. The protrusion 118 may be provided horizontally along the movement direction of the adjustment member 111. The protrusion 118 may also be provided on other sides or all sides of the adjustment member 111 in the movement direction of the adjustment belt 120, as shown in FIG. 6 .
[0047] 7 is a side view of a headrest plate 110 according to an embodiment. In this embodiment, the adjustment member 111 having two through holes 112 can be seen individually, as can the headrest attachment portion 117 protruding from the surface of the headrest plate 110. The adjustment member 111 includes at least one first positioning arm 111a and at least two second positioning arms 111b spaced apart to form the through holes 112.
[0048] FIG. 8 is a perspective view of a baby carrycot 1 according to an embodiment of the present disclosure. In FIG. 8, the headrest plate 110 has been removed, exposing details of the backrest 220. In this embodiment, two hollow portions 250 may be provided in the backrest 220, and the fixing member 130 is provided between the two hollow portions 250 along the longitudinal direction of the backrest 220. The fixing member 130 is provided in the backrest 220 along the longitudinal direction of the backrest 220, and both ends of the adjustment belt 120 are fixed to the fixing member 130. The fixing member 130 is fixedly connected to the backrest 220 or the seat main body 210 covered by the backrest 220 by screws 137A and 137B, and is configured to accommodate the adjustment belt 120. The adjustment belt 120 schematically shows a protrusion 122 formed by the adjustment member 111 (not shown).
[0049] 9 is a detailed view of the fixing member 130 of FIG. 8. The fixing member 130 is strip-shaped and fits the width and length of the adjustable belt 120. In this embodiment, the fixing member 130 is configured to have a groove that extends substantially along the longitudinal direction of the backrest portion 220 or the seat main body 210. The adjustment belt 120 is embedded in the groove of the fixing member 130, and the fixing member 130 with the adjustment belt 120 embedded therein is embedded in the backrest portion 220 and is fixedly connected to the backrest portion 220 or the seat main body 210 placed over the backrest portion 220 by screws 137A and 137B provided at connection portions 133 on both ends of the fixing member 130. The upper end of the adjustment belt 120 passes through the upper perforation 135 of the fixing member 130 and enters the back side of the fixing member 130, and the lower end passes through two lower perforations 135 in succession and is fixed to the lower connection part 133 by a screw 137B (see Figure 5).
[0050] FIG. 10 is a perspective view of a fixing member 130 according to an embodiment of the present disclosure. When the adjustment belt 120 of FIG. 9 is removed in FIG. 10, a groove formed in the fixing member 130 may be visible. The groove has a bottom portion 131 against which the adjustment belt 120 abuts and side portions 132 located on both sides of the bottom portion 131. In this embodiment, clamp wings 138 are provided at the longitudinal middle portions of the side portions 132, and the clamp wings 138 and the bottom portion 131 form a guide groove for guiding the sliding of the adjustment member 111. As a guide for the adjustment member 111, the guide groove can be advantageously used to prevent the headrest plate 110 from coming off the fixing member 130 and further from coming off the backrest portion 220. In this embodiment, one horizontal perforation 135 is provided at the upper end and two horizontal perforations 135 are provided at the lower end, forming, for example, a square-shaped configuration, as shown in FIG. 9. The screws 137A and 137B for fixing the fixing member 130 to the backrest portion 220 can be fixed through connection holes 134 provided in the connection portion 133 of the fixing member 130.
[0051] 11 is a top view of the fixed member 130 according to an embodiment of the present disclosure. This view shows clamp wings 138 disposed on two side portions 132 of the fixed member 130. The symmetrical arrangement of the two clamp wings 138 can better guide the stable movement of the adjustment member 111 and the adjustment belt 120.
[0052] Figure 12 is a schematic cross-sectional view of the fixing member 130 taken along line II-II in Figure 11. Figure 12 schematically shows the position of the clamping wing 138, and a guide groove for guiding the sliding of the adjustment member 111 is formed between the clamping wing 138 and the bottom part 131.
[0053] FIG. 13 shows a front view of the adjustment belt 120 according to an embodiment of the present disclosure and a cross-sectional view of the adjustment belt taken along line III-III. The adjustment belt 120 may be configured, for example, as a flat strip and made of a flexible material such as fabric. The adjustment belt 120 may have a rough surface to increase the coefficient of friction, or may have protrusions formed on its surface to increase the frictional force between the adjustment belt 120 and the adjustment member 111. Furthermore, to increase the frictional force of the adjustment belt 120 against the adjustment member 111, for example, a plurality of resistance devices (not shown) facing the adjustment member 111 may be provided on the adjustment belt 120 along the longitudinal direction. According to the present disclosure, the resistance devices may be protrusions, which may be stitching provided on one side of the adjustment belt 120 or other structures formed on the adjustment belt 120 itself. Furthermore, the resistance devices may be provided on the upper and / or lower sides of the adjustment belt 120 to individually or additionally increase the frictional force with the side of the backrest portion 220. 13 also shows two fixing holes 121 for fixing the adjustable belt 120 to both ends of the fixing member 130. According to the present disclosure, the fixing holes 121 do not have to be provided, but the flexible adjustable belt 120 may be fixed by directly passing through the fixing holes 121 using screws 137A and 137B (see FIG. 5).
[0054] FIG. 14 is a rear view of a headrest plate 110 according to an embodiment. In this embodiment, the headrest plate 110 is adapted to the fixing member 130 shown in FIGS. 9 to 12 of the present disclosure. The headrest plate 110 has a hollow portion 114A through which a shoulder strap can pass in the vertical direction and a hollow portion 114B for a screw 137A used to attach the fixing member 130. The headrest plate 110 also has a hollow portion 114C (protruding portion) formed in its horizontally intermediate portion, and an adjustment member 111 formed in this hollow portion 114C. Specifically, the adjustment member 111 is connected to the main body of the headrest plate 110 at both vertical ends of the headrest plate 110. Two side wings 113 (only one side wing 113 is shown due to the viewing angle) are provided symmetrically along the left-right direction on the bottom side of the adjustment member 111, which is raised vertically relative to the headrest plate 110 in FIG. 14. The side wings 113 protrude in the left-right direction from the adjustment belt 120 and can be inserted into the guide groove in Figure 12, allowing the adjustment member 111 to slide within the guide groove and preventing the headrest plate 110 from coming off the backrest portion 220.
[0055] Two through holes 112 are formed in the center of the bottom surface of the adjustment member 111 along the vertical direction, forming a square-shaped adjustment member 111 through which the adjustment belt 120 passes. The adjustment belt 120, together with the side wings 112, cooperates with the fixing member 130 to realize the relative displacement and positioning of the headrest plate 110 with respect to the backrest portion 220 in the vertical direction without requiring any other complex mechanism, thereby saving costs and reducing weight.
[0056] Additionally or alternatively, according to the present disclosure, the adjustment member 111 may have a positioning member 116A. The positioning members are provided symmetrically outside the through-hole 112 in the lateral direction of the headrest plate 110, avoiding the position of the adjustment belt 120. Here, four positioning members 116A are provided, and each has a circular or other convex shape, or rather a positioning protrusion shape, protruding from the bottom surface. The positioning members 116A and positioning portions such as recesses or positioning recesses provided in the groove of the fixing member 130 are configured to match (i.e., inserted into) each other in shape, thereby positioning the headrest plate 110.
[0057] Positioning member 116A may be provided on the outer surface of adjustment member 111 facing bottom 131 of the groove of fixed member 130, or may be provided on the outer surface of adjustment member 111 facing side surface 132 of the groove. In this embodiment, positioning member 116A is provided perpendicular to the outer peripheral surface of the bottom side of adjustment member 111 facing bottom 131 of the groove of fixed member 130. When a convex portion or positioning protrusion is provided in the vertical direction, the height of headrest 300 is adjusted by the user pulling the upper end portion of headrest 300 (for example, anti-slip rib 119 in FIG. 18 ). When adjusting the position of the headrest 300 due to the curvature of the headrest 110, i.e., because the upper end of the headrest plate 110 is not in the same horizontal plane as the adjustment member 111, on the one hand, a pulling force is applied vertically to the headrest plate 110 to move the headrest plate 110 away from the seat main body, and the convex portions or positioning protrusions provided on the surface of the adjustment member 111 of the headrest plate 110 at least partially disengage from the positioning recesses provided on the fixing member 130, thereby reducing resistance when adjusting the height of the headrest 300, and on the other hand, a pulling force is provided in the vertical direction of the headrest 300 along the length direction of the adjustment belt 120 to adjust the height of the headrest 300. When the convex portions or positioning protrusions are provided on the outer surface facing the bottom portion 131 of the groove, a more beneficial effect can be obtained compared to when the convex portions or positioning protrusions are provided on the outer surface facing the side portion 132 of the groove.
[0058] In addition to the positioning member 116A being configured as a convex portion or positioning protrusion and the positioning portion on the groove of the fixing member 130 being configured as a concave portion or positioning recess, it is also possible to provide the reverse configuration, i.e., a configuration in which a convex portion or positioning protrusion is provided on the groove of the fixing member 130 and a concave portion or positioning recess is provided on the adjustment member 111.
[0059] FIG. 15 is a perspective view of a fixing member 130 according to another embodiment of the present disclosure. Unlike the first embodiment of FIG. 10, the clamping wings 138 are not provided. Instead, positioning portions 136 are provided on the side surfaces 132 of the groove. The positioning portions 136 are configured as wavy positioning portions provided along the vertical direction. A positioning member 116B (see FIGS. 17 and 19) provided on the adjustment member 111 of the headrest plate 110 moves along the wavy positioning portion and is positioned in the trough. That is, in this embodiment, a plurality of positioning recess-shaped positioning portions 136 are provided. A plurality of positioning recesses are provided on the inner side surfaces 132 of the groove of the fixing member 130, and a protrusion is provided between two adjacent positioning recesses. When the adjustment member 111 is moved, the positioning members 116B in the form of a positioning protrusion are positioned in the positioning recesses on the protrusions, so that the headrest 300 can be stopped at an expected height.
[0060] The positioning protrusion on the headrest plate 110 matches with the positioning recess on the positioning member 130 to further position the headrest 300 and advantageously realize a split feeling during the adjustment process. When adjusting the headrest 300, when the positioning protrusion corresponds to the protrusion on the fixing member 130, the positioning member 116B on the elastic arm 115 is deformed, and the adjustment of the headrest 300 continues, and the positioning protrusion cooperates with the positioning recess to achieve the positioning of the headrest 300.
[0061] According to this embodiment, the positioning portion 136 can better position the headrest plate 110 or the headrest 300 and prevent it from slipping, while the adjustment belt 120 can connect the headrest plate 110 to the fixing member 130 or to the backrest portion 220 by using more diverse materials or shapes.
[0062] 16 is a top view of a fixing member 130 according to another embodiment of the present disclosure. Each of the troughs and peaks of the wavy positioning portion 136 extends substantially perpendicular to the bottom portion 131.
[0063] FIG. 17 is a rear view of the headrest plate 110 according to this embodiment. The headrest plate 110 according to this embodiment is fitted with the fixing member 130, as shown in FIGS. 15 and 16 . The headrest plate 110 has a hollow 114A through which a shoulder strap passes and a hollow 114B for a screw 137A for attaching the fixing member 130. The headrest plate 110 also has one or more anti-slip ribs 119 (three in this example) at its upper end. The anti-slip ribs 119 are used to prevent slippage between the headrest plate 110 and the backrest 220, thereby advantageously preventing movement of the headrest plate 110 relative to the backrest 220. Another purpose of the anti-slip ribs 119 is to allow the user to grip this portion to adjust the height of the headrest 300, thereby increasing the friction between the hand and the headrest plate 110.
[0064] An adjustment member 111 is formed in the horizontal center of the headrest plate 110, and two through holes 112 are formed on the underside of the adjustment member 111, forming a sun-shaped adjustment member 111 through which the adjustment belt 120 can pass.
[0065] Unlike the embodiment of FIG. 14, in this embodiment, two positioning members 116B are provided at the lower part of the underside of the adjustment member 111 in the form of protrusions or positioning protrusions to cooperate with the positioning portions 136 of the fixing member 130 of FIGS. 15 and 16. The positioning members 116B are, for example, integrally formed with hollow elastic arms 115 on the lateral sides of the adjustment member 111. The hollow portions provide deformation space for the positioning members 116B. That is, as shown in FIGS. 14 and 15, while the positioning members 116B move within the wavy positioning portions 136 of the grooves of the fixing member 130, they are pressed against the adjustment member 111 at their peaks by the action of the elastic arms 115, projected into the side portions 132 of the grooves at their troughs, and stopped at the corresponding troughs, thereby realizing stable positioning of the headrest plate 110 relative to the backrest 220.
[0066] The adjustment belt 120, together with the positioning member 116B, can advantageously achieve the relative displacement and positioning of the headrest plate 110 with respect to the backrest portion 220 by cooperating with the fixing member 130 without the need for any other complex mechanisms, thus saving costs and reducing weight.
[0067] Figure 18 is a side view of a headrest plate 110 in another embodiment. Unlike Figure 16, the recess depth of the adjustment member 111 is large and the headrest attachment portion 117 is configured to be low. In this embodiment, anti-slip ribs 119 provided on the headrest plate 110 can also be seen.
[0068] Figure 19 is a rear view of a headrest plate 110 in another embodiment. The headrest plate 110 in this embodiment is adapted to the fixing member 130 of Figures 15 and 16. The headrest plate 110 has a hollow portion 114A through which a safety belt can pass and a hollow portion 114B for a screw 137A used to attach the fixing member 130. The headrest plate 110 also has a headrest attachment portion 117 for attaching a headrest 300.
[0069] Unlike the embodiment of FIG. 17 , two additional adjustment members 111A are symmetrically provided on both sides of the adjustment member 111 in FIG. 19 to cooperate with the positioning portions 136 on the fixed member 130 of FIGS. 15 and 16 . The adjustment members 111A are also raised upward from the headrest plate 110, optionally to the same height as the adjustment member 111. An elastic arm 115 is hollowed out in the adjustment member 111A, and a positioning member 116B is provided on the elastic arm 115. According to this embodiment, the adjustment member 111 can be designed narrower in the horizontal direction. For example, to accommodate a narrow adjustment belt 120, only the distance between the positioning members 116B of the two adjustment members 111A needs to match the width of the groove in the fixed member 130. According to this embodiment, it is advantageous to diversify the designs of the adjustment members 111 and related components such as the adjustment belt 120.
[0070] The present disclosure provides a headrest structure for a baby carrycot 1, which includes an adjustment belt 120 fixed to a seat 200 and an adjustment member 111 provided on a headrest plate 110. The adjustment belt 120 realizes a connection between a headrest 300 and the seat 200 via the adjustment member 111, and the friction between the adjustment belt 120 and the adjustment member 111 provides a force for positioning the headrest 300 at different heights on the seat 200.
[0071] The adjustment belt 112 is securely connected to the backrest 220 area of the seat 200 of the baby carrycot 1, and an adjustment member 111 is directly formed on the headrest plate 110, so that the adjustment belt 120 passes through the adjustment member 111 to connect and adjust the position of the headrest 300 and the seat 200. The simple structure, the lightweight adjustment belt 120, and the thin and lightweight headrest plastic also reduce the overall weight of the baby carrycot 1, providing convenience for caregivers when carrying the baby carrycot 1 during travel.
[0072] Because the present disclosure can be embodied in various forms without departing from the spirit and essence of the present disclosure, the above-described embodiments are not limited to the details set forth above, but should be construed as broadly as possible within the scope defined by the claims, and therefore, it should be understood that all modifications that come within the scope of the claims or equivalents thereof are intended to be covered by the claims.
