Description

[Technical field]

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

[0002] A child car seat is a device that is attached to a car seat and restrains a child on it with a seat belt. When the car is braked or crashes in an emergency, it can effectively prevent the child's body from moving rapidly, avoid a secondary collision, reduce injuries to the child, provide strong protection and restraint for the child, and ensure the safety of the child when seated.

[0003] Current child seats are generally equipped with a seat cushion (or called a small seat cushion) to accommodate use by infants and small children. In order to improve the support effect of the seat cushion, a support structure is further installed on the rear surface of the seat cushion to form a seat cushion structure, which can better support the child. One problem with the current support structure is that it cannot provide a good protective effect while providing a supporting effect. More specifically, although the current seat cushion structure can provide a supporting effect to the child in a normal state, the protective effect of the seat cushion structure is low when the vehicle is impacted. In particular, when the seat cushion structure is impacted, the position corresponding to the child's back and buttocks cannot be sufficiently deformed, and therefore the child's back and buttocks cannot be better protected.

[0029] Although the invention is described herein with reference to specific embodiments, the invention should not be limited to the details shown, in particular, various modifications can be made to these details within the scope and range of equivalence of the claims and without departing from the invention.

[0030] The descriptions of directions such as "front", "back", "upper", and "lower" referred to in this specification are for convenience of understanding only, and the present invention is not limited to these directions and can be adjusted according to actual circumstances.

[0031] A support structure 100 according to a first embodiment of the present application will be described with reference to Fig. 1. The support structure 100 includes a support 110 and at least one buffer part 120, and the buffer part 120 is installed within the support 110. Note that the support structure 100 and the buffer part 120 can both provide a supporting function and a buffering function.

[0032] For convenience of explanation, in this specification, the support structure 100 is described as having a vertical direction, a horizontal direction, and a front-rear direction according to the seating direction of the child seat to which the support structure 100 is attached, as shown by the arrows in each direction in FIG. 1. The support structure 100 has a support surface 123 (which is the support surface 123 of the buffer part 120 in this embodiment) for supporting a child, and is, for example, a surface that faces approximately forward. In order to accommodate various seating needs, the support surface 123 can extend along a direction of inclination and / or curvature. Therefore, the extension direction of the support surface 123 is referred to as a vertical direction. In this embodiment, the extension direction of the support surface 123 is inclined downward and forward with respect to the vertical direction, and a curved portion that protrudes forward is formed in the center.

[0033] The assembly relationship between the support 110 and the buffer part 120 will be described with reference to Fig. 2. The support 110 has a frame structure and includes a receiving part 114 for receiving the buffer part 120, and the receiving part 114 penetrates the support 110 in a direction perpendicular to the support surface 123. Therefore, the support 110 is formed as a hollow frame.

[0034] In this embodiment, the support 110 extends along the lateral and vertical directions and includes a top edge 112, a bottom edge 113, and two side edges 111 connecting between the top edge 112 and the bottom edge 113. A notch 113a is provided at the center of the bottom edge 113, and the notch 113a is recessed into the bottom edge 113 along the front-rear direction to allow a seat belt or straddle belt (not shown) to pass through the support 110. In other embodiments, the notch 113a may not be provided.

[0035] The shape of the bumper 120 corresponds substantially to the shape of the receiving portion 114 , thereby allowing the bumper 120 to be stably mounted within the support 110 .

[0036] 3 to 4C, the specific structure of the buffer part 120 will be described. The buffer part 120 includes a support surface 123, a rear surface 124, a top surface 125, a bottom surface 126 and two side surfaces 127.

[0037] More specifically, the central portion along the longitudinal direction of the support surface 123 protrudes forward, and the bottom end curves forward. The back surface 124 faces the support surface 123, and the bottom end of the back surface 124 curves forward. The top surface 125 slopes downward and rearward. The bottom surface 126 faces the top surface 125, and also slopes downward and rearward. The bottom surface 126 may be larger than the top surface 125. The two side surfaces 127 face each other and are (almost) flat. The thickness of the top surface 125 of the buffer portion 120 is smaller than the thickness of the bottom surface 126.

[0038] It should be noted that the cushion 120 may be formed in other suitable shapes to allow a child to sit comfortably or to accommodate different child seats.

[0039] The buffer unit 120 includes a plurality of adjacent buffer blocks 129. At least one first slit 121 is disposed on the support surface 123 of the buffer unit 120, and the first slit 121 divides the buffer unit 120 into a plurality of buffer blocks 129, and the plurality of buffer blocks 129 are connected to each other at least one position other than the support surface 123 of the buffer unit 120.

[0040] More specifically, the first slits 121 extend in the vertical direction of the support surface 123 and are arranged along the horizontal direction of the support surface 123 .

[0041] In this embodiment, five first slits 121 are arranged side by side along the horizontal direction, thereby dividing the buffer section 120 into six laterally adjacent buffer blocks 129. In other embodiments, more or less first slits 121 may be provided.

[0042] The buffer blocks 129 are connected to each other at least at the back surface 124 opposite to the support surface 123 of the buffer unit 120. In this embodiment, the first slits 121 penetrate the top surface 125 and the bottom surface 126 of the buffer unit 120, as shown in FIG. 4A and FIG. 4B. The first slits 121 extend from the support surface 123 toward the back surface 124, but do 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 slits 121 may be 50% to 90% of the thickness of the buffer unit 120, and the depth ratio may vary along the vertical direction. The depth of each first slit 121 may be different. For example, the first slit 121 in the center may have a deeper depth, and the first slits 121 at the edge may have a shallower depth. Please refer to the depth indication line DL in FIG. 4C, which shows the depth of at least one first slit 121.

[0043] In each embodiment of the present application, the first slits 121 can be formed by machining using a CNC computer or a cutting die. That is, the entire buffer unit 120 can be cut to form a plurality of buffer blocks 129. However, the present application is not limited to such a manufacturing method, and the buffer unit 120 having the first slits 121 can be integrally formed by molding, or the buffer unit 120 can be formed by bonding a plurality of buffer blocks 129.

[0044] For ease of understanding, the first slit 121 is depicted as having a constant width in Figures 3 to 4C. It should be understood that the width depicted in the figures does not represent the actual width of the first slit 121.

[0045] In each embodiment of the present application, the first slit 121 may have a very small width, so that adjacent buffer blocks 129 form cross sections facing each other 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 hardly be found. The first slit 121 may have a constant width, so that adjacent buffer blocks 129 form cross sections facing each other through the first slit 121, and there is a gap between the adjacent cross 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 varying width, for example, narrow at the support surface 123 and wide near the bottom surface 126.

[0046] Since the buffer part 120 is divided into a plurality of mutually connected buffer blocks 129, the buffer part 120 can be easily provided in the support and the loss of the buffer part 120 can be avoided. During normal sitting, the support structure 100 has a certain hardness and can support the child's hips and back. During emergency braking or collision, each buffer block 129 can provide a larger deformation, and receive and disperse the impact force. For example, the buffer block 129 located in the lateral center where pressure is concentrated can provide a larger deformation than the buffer block 129 located at the edge, thereby better protecting the child's hips and back.

[0047] In contrast, if the buffer part 120 is formed as an integral part, it cannot provide sufficient deformation to the pressure concentration area, and therefore has poor impact dispersion properties. On the other hand, if the buffer part 120 includes a plurality of buffer blocks 129 that are completely separated from each other, the buffer part 120 cannot provide sufficient support as a whole.

[0048] In addition, when multiple buffer blocks 129 are connected to each other on the back surface 124 and a gap exists between adjacent cross sections formed by the first slits 121, if the support surface 123 receives a large force, the two adjacent cross sections may come into contact at locations close to the support surface 123, and a gap may be maintained at a location close to the connection position. In other words, the support structure 100 of the present application not only allows the buffer section 120 to deform in a direction perpendicular to the support surface 123, but also allows the buffer section 120 to deform in a direction parallel to the support surface 123, thereby providing a good buffering effect.

[0049] A support structure 100 according to a second embodiment of the present invention will be described with reference to FIGS.

[0050] The support structure 100 according to the second embodiment is almost the same as the first embodiment, and the difference between the two is the different direction of the first slits 121 of the buffer part 120. In the second embodiment, the multiple first slits 121 extend in the lateral direction of the support surface 123 and are arranged along the longitudinal direction of the support surface 123. Therefore, the buffer part 120 includes multiple buffer blocks 129 arranged along the longitudinal direction of the support surface 123, and each buffer block 129 has a rectangular shape extending along the lateral direction. In this way, the buffer part 120 can effectively distribute the impact force along the longitudinal direction.

[0051] A support structure 100 according to a third embodiment of the present invention will be described with reference to FIGS.

[0052] The third embodiment is different from the first embodiment in that the buffer unit 120 according to 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. The at least one second slit 122 is disposed on the support surface 123, and the second slit 122 crosses the first slit 121. The first slit 121 extends in the vertical direction of the support surface 123, and the second slit 122 extends in the horizontal direction of the support surface 123. Thus, the buffer unit 120 includes a plurality of buffer blocks 129 arranged along the vertical and horizontal directions, and each buffer block 129 has a substantially rectangular shape. In this way, the buffer unit 120 can effectively distribute the impact force along the vertical and horizontal directions. The plurality of buffer blocks 129 are also connected to each other at the back surface 124.

[0053] A support structure 100 according to a fourth embodiment of the present invention will be described with reference to FIGS.

[0054] In the fourth embodiment, the buffer unit 120 is divided into a plurality of buffer blocks 129 by at least one first slit 121 and at least one second slit 122. The difference from the third embodiment is that the first slit 121 extends in one diagonal direction of the support surface 123, and the second slit 122 extends in another diagonal direction of the support surface 123. For example, the first slit 121 and the second slit 122 may have approximately the same inclination angle with respect to the vertical direction of the support surface 123. Thus, the buffer unit 120 includes a plurality of diamond-shaped and triangular buffer blocks 129 arranged along two mutually intersecting diagonal directions. In this way, the buffer unit 120 can effectively distribute impact forces along two mutually intersecting diagonal directions.

[0055] A support structure 100 according to a fifth embodiment of the present invention will be described with reference to FIGS.

[0056] The support structure 100 according to the fifth embodiment includes a plurality of buffer sections 120 arranged side by side in a support 110. Two adjacent buffer sections 120 may be in contact with each other or may have a gap therebetween. Each buffer section 120 extends along the horizontal direction, and the plurality of buffer sections 120 are arranged along the vertical direction of a support surface 123. At least one first slit 121 divides each buffer section 120 into a plurality of buffer blocks 129. For example, as shown in FIG. 17, each buffer section 120 is a rectangle extending in the horizontal direction, and at least one first slit 121 extending along the vertical direction divides the buffer section 120 into a plurality of buffer blocks 129 arranged along the horizontal direction.

[0057] A support structure 100 according to a sixth embodiment of the present invention will be described with reference to FIGS.

[0058] The support structure 100 according to the sixth embodiment is similar to the fifth embodiment, including a plurality of buffer sections 120. Unlike the fifth embodiment, each buffer section 120 in the sixth embodiment extends along the vertical direction, and the plurality of buffer sections 120 are arranged along the horizontal direction. At least one first slit 121 extending along the horizontal direction divides each buffer section 120 into a plurality of buffer blocks 129 adjacent to each other along the vertical direction.

[0059] In addition, in other embodiments having multiple buffer sections 120, each buffer section 120 may extend along other directions, for example extending along a diagonal direction, and the direction of the first slits 121 may be changed accordingly, as long as the buffer section 120 is divided into multiple buffer blocks 129.

[0060] A support structure 100 according to a seventh embodiment of the present invention will be described with reference to FIGS.

[0061] In the support structure 100 of the seventh embodiment, the first slits 121 penetrate the back surface 124 opposite to the support surface 123 of the buffer part 120, and the buffer blocks 129 are connected to each other at the top surface 125 and the bottom surface 126 of the buffer part 120. More specifically, each of the first slits 121 extends along the vertical direction and extends from the support surface 123 to the back surface 124. That is, the first slits 121 penetrate the support surface 123 and the back surface 124, and therefore the multiple buffer blocks 129 divided by the first slits 121 are not connected to each other at the back surface 124.

[0062] In this embodiment, the first slit 121 does not penetrate the top surface 125 and the bottom surface 126 of the buffer part 120, so that the buffer blocks 129 can be connected to each other at the top surface 125 and the bottom surface 126. In another embodiment, the first slit 121 may 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 surface. In addition, multiple buffer blocks 129 may be connected to each other at the top surface 125 and the bottom surface 126 of the buffer part 120 and at the same time connected to each other at the back surface 124. It is to be noted that the first slit 121 may extend along the lateral direction and penetrate the support surface 123 and the back surface 124 of the buffer part 120, so that the buffer blocks 129 are connected to each other at any side surface 127 of the buffer part 120.

[0063] A support structure 100 according to an eighth embodiment of the present invention will now be described with reference to FIG.

[0064] In the eighth embodiment, the buffer part 120 is substantially circular, at least one first slit 121 penetrates the support surface 123 and the back surface 124 of the buffer part 120, and the buffer blocks 129 divided by the first slit 121 are connected to each other at the periphery 128 of the buffer part 120. In addition, the multiple buffer blocks 129 may be further connected to each other at the periphery 128 of the buffer part 120, or may be connected to each other at the back surface 124.

[0065] In addition, in each embodiment of the present application, the buffer part 120 may be a circle similar to the eighth embodiment, and the buffer part 120 may have other suitable geometric shapes, such as a trapezoid, a triangle, an octagon, etc., to meet the needs of different child seats. In addition, in each embodiment of the present application, the buffer part 120 may be detachably connected to the support 110, for example, the buffer part 120 is inserted into the receiving part 114, and at least one outermost surface of the buffer part 120 and the inner surface of the receiving part 114 are abutted against each other, and the size of the buffer part 120 may be slightly larger than the size of the receiving part 114, so that the buffer part 120 can be relatively stably installed in the receiving part 114 without being glued. In addition, the support 110 has a frame structure, and after the buffer part 120 is received in the receiving part 114, the buffer part 120 can be restricted around the frame structure, so that the risk of the buffer part 120 being separated from the support 110 can be reduced.

[0066] A support structure 100 according to a ninth embodiment of the present invention will now be described with reference to FIG.

[0067] In the ninth embodiment, the support 110 and the buffer part 120 are an integrally molded whole. 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 part 120 can also be regarded as the corresponding surfaces of the support 110. At least one first slit 121 extends along the vertical direction and penetrates the support surface 123 and the back surface 124, so that the multiple buffer blocks 129 are connected to each other at the top surface 125 and the bottom surface 126. Note that in this embodiment, the first slit 121 may extend along the horizontal or oblique direction of the support surface 123.

[0068] In each embodiment of the present application, the hardness or density of the buffer part 120 may be equal to or lower than the hardness or density of the support 110. The hardness of the buffer part 120 is 17 kg / m 3 ~29kg / m 3 For example, 17 kg / m 3 , 21kg / m 3 or 29 kg / m 3The hardness of the support 110 is 32 kg / m 3 ~40kg / m 3 For example, 32 kg / m 3 , 37kg / m 3 or 40kg / m 3 It is.

[0069] In each embodiment of the present application, the buffer part 120 and the support 110 may be made of different materials. For example, the buffer part 120 is made of foam cotton, and the support 110 is made of memory cotton, latex, or silica gel. In each embodiment of the present application, the buffer part 120 and the support 110 may be made of the same material. In addition, the buffer part 120 is divided into a plurality of buffer blocks 129, and the plurality of buffer blocks 129 are connected to each other, compared with a case where the buffer part 120 is not divided, and the support structure 100 of the present application can increase the amount of buffer deformation when subjected to impact force, and also facilitate the formation of the support structure 100 (for example, when the buffer part 120 and the support 110 are attached to each other in a separate structure to form the support structure 100, each buffer part 120 can be easily attached to the support 110 as an integral part because the plurality of buffer blocks 129 are connected to each other. When the buffer part 120 and the support 110 are an integral structure, the installation process can be further reduced).

[0070] In addition, the necessary support force and cushioning deformation amount can be achieved by adjusting each structure in the support structure 100 comprehensively. For example, when the cushioning blocks 129 are connected to each other at the back surface 124, a large support force can be provided by the back surface 124, compared with a situation in which the cushioning blocks 129 are not connected to each other at the back surface 124 and the first slits 121 penetrate the back surface 124. The cushioning deformation amount of the support structure 100 can be supplemented by a method such as increasing the number of the cushioning blocks 129, increasing the depth of the first slits 121, or increasing the gap between two adjacent cushioning blocks 129. In addition, when the cushioning blocks 129 are connected to each other at the back surface 124, a good cushioning deformation amount can be provided when the first slits 121 penetrate the back surface 124, compared with a situation in which the cushioning blocks 129 are connected to each other at the back surface 124. At the same time, the support force of the support structure 100 can be supplemented by a method such as decreasing the number of the cushioning blocks 129 or shortening the distance between two adjacent cushioning blocks 129.

[0071] The seat cushion structure according to the present invention will be described with reference to FIG.

[0072] The seat cushion structure includes a seat cushion 200, a support structure 100 and a cover member 300.
