Description

Technical Field

[0001] The present disclosure relates to a support structure, a seat cushion structure including the support structure, and a child safety seat including the seat cushion structure. Background Art

[0002] A child safety seat is a device that is installed on a car seat and restrains the child on it with a seat belt. In the event of emergency braking or a collision, it can effectively prevent the child's body from moving rapidly, avoid secondary collisions, reduce injuries to the child, provide strong protection and restraint for the child, and ensure the child's safety while riding.

[0003] Existing child safety seats are generally provided with a seat cushion (or small seat cushion) to accommodate infants and young children. In order to enhance the support effect of the seat cushion, a support structure is also provided on the back of the seat cushion to form a seat cushion structure to provide better support for the child. One problem with the existing support structure is that it is unable to provide good protection while providing support. More specifically, although the existing seat cushion structure can provide support for children under normal conditions, the seat cushion structure does not provide good protection when the vehicle is impacted. In particular, when the seat cushion structure is impacted, it cannot deform sufficiently at the child's back and buttocks, thereby failing to provide better protection for the child's back and buttocks.

[0004] For this reason, it is necessary to provide a new seat cushion structure, which can provide support under normal conditions and provide enough deformation to absorb collision energy when impacted. In addition, the seat cushion structure needs to have a simple mechanism as much as possible, so as to facilitate manufacturing and reduce costs. Summary of the invention

[0075] While the invention is illustrated and described herein with reference to particular embodiments, the invention should not be limited to the details shown, rather various modifications may be made to the details within the range and scope of equivalents of the claims and without departing from the invention.

[0076] The descriptions of directions such as “front”, “back”, “up” and “down” involved in this article are only for the convenience of understanding. The present invention is not limited to these directions but can be adjusted according to actual conditions.

[0077] Reference Figure 1 The support structure 100 according to the first embodiment of the present application is described. The support structure 100 includes a support body 110 and at least one buffer portion 120, and the buffer portion 120 is disposed in the support body 110. It should be understood that the support structure 100 and the buffer portion 120 can both provide support and buffer effects.

[0078] For ease of description, in this document, the support structure 100 is described as having up-down, lateral, and front-back directions, according to the seating direction of the child safety seat on which the support structure 100 is installed. Figure 1 As shown by the arrows in the directions. The support structure 100 has a support surface 123 for supporting a child (in this embodiment, it is the support surface 123 of the buffer portion 120), for example, a substantially forward surface. In order to meet various riding requirements, the support surface 123 can extend in an inclined and / or curved direction. Therefore, the extension direction of the support surface 123 is referred to as the longitudinal direction. In this embodiment, the extension direction of the support surface 123 is inclined toward the lower front relative to the up-down direction, and a curved portion protruding forward is formed in the middle.

[0079] Reference Figure 2 The assembly relationship between the support body 110 and the buffer portion 120 is described. The support body 110 is a frame structure and includes a receiving portion 114 for receiving the buffer portion 120. The receiving portion 114 penetrates the support body 110 in a direction orthogonal to the support surface 123. Therefore, the support body 110 is formed as a hollow frame.

[0080] In this embodiment, the support body 110 extends in the lateral and vertical directions, and includes a top edge 112, a bottom edge 113, and two side edges 111 connected between the top edge 112 and the bottom edge 113. A notch 113a is provided in the middle of the bottom edge 113, and the notch 113a is recessed into the bottom edge 113 in the front-to-back direction to allow a safety belt or a strap (not shown) to pass through the support body 110. In other embodiments, the notch 113a may not be provided.

[0081] The shape of the buffer portion 120 substantially corresponds to the shape of the receiving portion 114 , so that the buffer portion 120 is stably installed in the support body 110 .

[0082] Reference Figures 3 to 4C The specific structure of the buffer portion 120 is described. The buffer portion 120 includes a support surface 123 , a back surface 124 , a top surface 125 , a bottom surface 126 and two side surfaces 127 .

[0083] More specifically, the middle portion of the support surface 123 along the longitudinal direction is convex forward, and the bottom end is bent forward. The back surface 124 is opposite to the support surface 123, and the bottom end of the back surface 124 is bent forward. The top surface 125 is inclined downward and backward. The bottom surface 126 is opposite to the top surface 125 and is inclined downward and backward. The bottom surface 126 can be larger than the top surface 125. The two side surfaces 127 are opposite to each other and (roughly) flat. The thickness of the buffer portion 120 at the top surface 125 is less than the thickness at the bottom surface 126.

[0084] It should be understood that the cushioning portion 120 may be formed in other appropriate shapes to facilitate a child to sit comfortably or to fit different child safety seats.

[0085] The buffer portion 120 includes a plurality of adjacent buffer blocks 129. At least one first slit 121 is provided on the support surface 123 of the buffer portion 120, and the first slit 121 divides the buffer portion 120 into a plurality of buffer blocks 129, which are connected to each other at at least one position of the buffer portion 120 except the support surface 123.

[0086] More specifically, the plurality of first slits 121 extend in the longitudinal direction of the support surface 123 and are arranged along the transverse direction of the support surface 123 .

[0087] In this embodiment, five first slits 121 are arranged in parallel in the transverse direction, so as to divide the buffer portion 120 into six buffer blocks 129 adjacent in the transverse direction. In other embodiments, more or fewer first slits 121 may be provided.

[0088] The plurality of buffer blocks 129 are connected to each other at least at the back surface 124 of the buffer portion 120 opposite to the support surface 123. In this embodiment, the first gap 121 penetrates the top surface 125 and the bottom surface 126 of the buffer portion 120. Figure 4A and Figure 4B As shown. The first slit 121 extends from the support surface 123 toward the back surface 124, but does not penetrate the back surface 124, so that the buffer blocks 129 are connected to each other at the back surface 124. The depth of the first slit 121 can be 50%-90% of the thickness of the buffer portion 120, and the depth ratio can be changed along the longitudinal direction. In addition, the depth of each first slit 121 can be different. For example, the first slit 121 in the middle can have a larger depth, while the first slit 121 at the edge can have a smaller depth. Figure 4C A depth schematic line DL schematically shows the depth of at least one first gap 121.

[0089] In various embodiments of the present application, the first slit 121 can be formed by CNC machine or die cutting. That is, a plurality of buffer blocks 129 can be formed by cutting the overall buffer portion 120. It should be understood that the present application is not limited to this manufacturing method, and the buffer portion 120 having the first slit 121 can be integrally formed by molding, or the buffer portion 120 can be formed by bonding a plurality of buffer blocks 129.

[0090] For ease of understanding, Figures 3 to 4C In the figure, the first slit 121 is drawn as having a certain width. It should be understood that the width shown in the figure does not represent the actual width of the first slit 121.

[0091] In various embodiments of the present application, the first slit 121 may have a very small width, so that adjacent buffer blocks 129 respectively form sections facing and contacting each other through the first slit 121. In this way, in actual use, especially when the buffer block 129 is not deformed, the first slit 121 can be almost invisible. The first slit 121 may also have a certain width, so that adjacent buffer blocks 129 respectively form sections facing each other through the first slit 121, and there is a gap between adjacent sections. In addition, the first slit 121 may have a uniform width in the direction from the support surface 123 to the bottom surface 126, or may have a variable width, for example, narrower at the support surface 123 and wider near the bottom surface 126.

[0092] Since the buffer portion 120 is divided into a plurality of buffer blocks 129 connected to each other, the buffer portion 120 can be conveniently arranged in the support body to avoid the loss of the buffer portion 120. During normal riding, the support structure 100 has a certain hardness and can support the child's buttocks and back. During emergency braking or collision, each buffer block 129 can provide greater deformation to withstand and disperse the impact force. For example, the buffer block 129 located in the middle of the horizontal direction where the pressure is concentrated can provide greater deformation than the buffer block 129 located at the edge, thereby better protecting the child's buttocks and back.

[0093] In contrast, when the buffer portion 120 is formed as a whole, the buffer portion 120 cannot provide sufficient deformation at the pressure concentration point, and thus the performance of bearing and dispersing the impact force is weak. On the other hand, when the buffer portion 120 includes a plurality of buffer blocks 129 that are completely separated from each other, the buffer portion 120 cannot provide sufficient supporting force as a whole.

[0094] It should be noted that when the plurality of buffer blocks 129 are connected to each other at the back surface 124, and the first gap 121 forms a gap between adjacent sections, if the support surface 123 is subjected to a large force, two adjacent sections may fit together near the support surface 123, and a gap is maintained at the adjacent connection position. That is, the support structure 100 of the present application not only allows the buffer portion 120 to deform in a direction orthogonal to the support surface 123, but also allows the buffer portion 120 to deform in a direction parallel to the support surface 123, thereby providing a better buffering effect.

[0095] Reference Figures 5 to 7 A support structure 100 according to a second embodiment of the present application is described.

[0096] The support structure 100 of the second embodiment is substantially the same as the first embodiment, and the difference between the two is that the directions of the first slits 121 of the buffer portion 120 are different. In the second embodiment, a plurality of first slits 121 extend in the transverse direction of the support surface 123 and are arranged along the longitudinal direction of the support surface 123. Therefore, the buffer portion 120 includes a plurality of buffer blocks 129 arranged along the longitudinal direction of the support surface 123, and each buffer block 129 is rectangular and extends in the transverse direction. In this way, the buffer portion 120 can advantageously disperse the impact force along the longitudinal direction.

[0097] Reference Figures 8 to 10 A support structure 100 according to a third embodiment of the present application is described.

[0098] The difference between the third embodiment and the first embodiment is that the buffer portion 120 of the third embodiment is divided into a plurality of buffer blocks 129 by at least one first slit 121 and at least one second slit 122. At least one second slit 122 is provided on the support surface 123, and the second slit 122 intersects with the first slit 121. The first slit 121 extends in the longitudinal direction of the support surface 123, and the second slit 122 extends in the transverse direction of the support surface 123. Therefore, the buffer portion 120 includes a plurality of buffer blocks 129 arranged in the longitudinal direction and in the transverse direction, and each buffer block 129 is roughly square. In this way, the buffer portion 120 can advantageously disperse the impact force in the longitudinal direction and in the transverse direction. The plurality of buffer blocks 129 are also interconnected at the back surface 124.

[0099] Reference Figures 11 to 13 A support structure 100 according to a fourth embodiment of the present application is described.

[0100] In the fourth embodiment, the buffer portion 120 is divided into a plurality of buffer blocks 129 by at least one first slit 121 and at least one second slit 122. Different from the third embodiment, the first slit 121 extends in an oblique direction of the support surface 123, and the second slit 122 extends in another oblique direction of the support surface 123. For example, the first slit 121 and the second slit 122 may have substantially the same inclination angle relative to the longitudinal direction of the support surface 123. Therefore, the buffer portion 120 includes a plurality of rhombus and triangular buffer blocks 129 arranged along two mutually intersecting oblique directions. In this way, the buffer portion 120 can advantageously disperse the impact force along two mutually intersecting oblique directions.

[0101] Reference Figures 14 to 17 A support structure 100 according to a fifth embodiment of the present application is described.

[0102] The support structure 100 of the fifth embodiment includes a plurality of buffer portions 120 arranged in parallel in the support body 110. Two adjacent buffer portions 120 may be in contact with each other or have a gap therebetween. Each buffer portion 120 extends in the transverse direction, and the plurality of buffer portions 120 are arranged in the longitudinal direction of the support surface 123. At least one first gap 121 divides each buffer portion 120 into a plurality of buffer blocks 129. For example, referring to Fig.17 Each buffer portion 120 is in the shape of a transversely extending rectangle, and at least one first slit 121 extending along the longitudinal direction divides the buffer portion 120 into a plurality of transversely arranged buffer blocks 129 .

[0103] Reference Figures 18 to 20 A support structure 100 according to a sixth embodiment of the present application is described.

[0104] The support structure 100 of the sixth embodiment includes a plurality of buffer portions 120, similar to the fifth embodiment. Different from the fifth embodiment, each buffer portion 120 of the sixth embodiment extends in the longitudinal direction, and the plurality of buffer portions 120 are arranged in the transverse direction. At least one first slit 121 extending in the transverse direction divides each buffer portion 120 into a plurality of buffer blocks 129 adjacent to each other in the longitudinal direction.

[0105] It should be understood that in other embodiments having multiple buffer portions 120 , each buffer portion 120 may also extend in other directions, such as extending obliquely, and the direction of the first gap 121 may also be changed accordingly, as long as the buffer portion 120 can be divided into multiple buffer blocks 129 .

[0106] Reference Figure 21 to Figure 22 A support structure 100 according to a seventh embodiment of the present application is described.

[0107] In the support structure 100 of the seventh embodiment, the first slit 121 penetrates the back surface 124 of the buffer portion 120 opposite to the support surface 123, and the buffer blocks 129 are connected to each other at the top surface 125 and the bottom surface 126 of the buffer portion 120. More specifically, each first slit 121 extends in the longitudinal direction and extends from the support surface 123 to the back surface 124. That is, the first slit 121 penetrates the support surface 123 and the back surface 124, so the plurality of buffer blocks 129 divided by the first slit 121 are not connected to each other at the back surface 124.

[0108] In the present embodiment, the first slit 121 does not penetrate the top surface 125 and the bottom surface 126 of the buffer portion 120, so the buffer blocks 129 can be connected to each other at the top surface 125 and the bottom surface 126. In other embodiments, the first slit 121 may also penetrate the top surface 125 or one of the top surfaces 125, so that the buffer blocks 129 are connected to each other at the other one. In addition, the plurality of buffer blocks 129 may also be connected to each other at the top surface 125 and the bottom surface 126 of the buffer portion 120, and at the same time connected to each other at the back surface 124. It should also be understood that the first slit 121 may also extend in the transverse direction and penetrate the support surface 123 and the back surface 124 of the buffer portion 120, so that the buffer blocks 129 are connected to each other at any side surface 127 of the buffer portion 120.

[0109] Reference Fig.23 A support structure 100 according to an eighth embodiment of the present application is described.

[0110] In the eighth embodiment, the buffer portion 120 is substantially circular, at least one first slit 121 penetrates the support surface 123 and the back surface 124 of the buffer portion 120, and the buffer blocks 129 divided by the first slit 121 are connected to each other at the periphery 128 of the buffer portion 120. In addition, the plurality of buffer blocks 129 may be connected to each other both at the periphery 128 of the buffer portion 120 and at the back surface 124.

[0111] It should be understood that in each embodiment of the present application, the buffer portion 120 can be a circle similar to the eighth embodiment, and the buffer portion 120 can also have other appropriate geometric shapes, such as a trapezoid, a triangle, an octagon, etc., to adapt to the needs of different child safety seats. It should be noted that in the above embodiments of the present application, the buffer portion 120 can be detachably connected to the support body 110, for example, the buffer portion 120 is inserted into the accommodating portion 114, so that at least one outermost surface of the buffer portion 120 and the inner surface of the accommodating portion 114 abut against each other, and the size of the buffer portion 120 can be slightly larger than the size of the accommodating portion 114, even if it is not bonded, it can ensure that the buffer portion 120 is relatively stably arranged in the accommodating portion 114. In addition, the support body 110 is a frame structure. After the buffer portion 120 is accommodated in the accommodating portion 114, the buffer portion 120 can be limited around the frame structure, and the risk of the buffer portion 120 detaching from the support body 110 can also be reduced.

[0112] Reference Fig.24 A support structure 100 according to a ninth embodiment of the present application is described.

[0113] In the ninth embodiment, the support body 110 and the buffer portion 120 are integrally formed. Therefore, the support surface 123, the back surface 124, the top surface 125, the bottom surface 126, and the side surface 127 of the buffer portion 120 can also be considered as the corresponding surfaces of the support body 110. At least one first slit 121 extends in the longitudinal direction and penetrates the support surface 123 and the back surface 124, so that the plurality of buffer blocks 129 are connected to each other at the top surface 125 and the bottom surface 126. It should be understood that in this embodiment, the first slit 121 can also extend in the lateral or oblique direction of the support surface 123.

[0114] In various embodiments of the present application, the hardness or density of the buffer portion 120 may be less than or equal to the hardness or density of the support body 110. The hardness of the buffer portion 120 may be between 17 kg / m 3 Up to 29kg / m 3 Between, for example, 17kg / m 3 , 21kg / m 3 or 29kg / m 3 The hardness of the support 110 can be 32 kg / m 3 Up to 40kg / m 3 Between, for example, 32kg / m 3 、37kg / m 3 or 40kg / m 3 .

[0115] In various embodiments of the present application, the buffer portion 120 and the support body 110 may be made of different materials. For example, the buffer portion 120 is made of foam, and the support body 110 is made of memory foam, latex or silicone. In addition, in various embodiments of the present application, the buffer portion 120 and the support body 110 may be made of the same material. It should be understood that the buffer portion 120 is divided into a plurality of buffer blocks 129 and the plurality of buffer blocks 129 are connected to each other. Compared with not being divided, the support structure 100 of the present application can increase the amount of buffer deformation when it is subjected to impact force, and facilitate the molding of the support structure 100 (for example, when the buffer portion 120 and the support body 110 are split structures and are installed to each other to form the support structure 100, since the plurality of buffer blocks 129 are connected to each other, it is convenient to install each buffer portion 120 as a whole into the support member 110; when the buffer portion 120 and the support body 110 are an integrated structure, the installation process can be further reduced).

[0116] It should be noted that the various structures in the support structure 100 can be comprehensively adjusted to achieve the required supporting force and buffering deformation. For example, compared with the situation where multiple buffer blocks 129 are not connected at the back and the first gap 121 passes through the back 124, when multiple buffer blocks 129 are connected to each other at the back 124, they can provide a larger supporting force through the back 124. The buffer deformation of the support structure 100 can be compensated by increasing the number of the buffer blocks 129, increasing the depth of the first gap 121, or increasing the gap between two adjacent buffer blocks 129. For example, compared with the situation where multiple buffer blocks 129 are connected to each other at the back 124, when the first gap 121 passes through the back 124, it can provide a better buffering deformation. At the same time, the supporting force of the support structure 100 can be compensated by reducing the number of the buffer blocks 129 or shortening the distance between two adjacent buffer blocks 129.
