Description

[0001] Divisional Application Statement

[0002] This application is a divisional application of the Chinese invention patent application filed on May 31, 2018, with the invention name “Fireproof buffer structure, support cushion device and safety seat” and application number 201810551224.X. Technical Field

[0004] The child car safety seat provides a suitable seating space for the child, and a buffer structure is provided on the inner wall in contact with the child to play a buffering role in the event of a collision and reduce the chance of the child being injured. The buffer structure can be fixed to the body of the safety seat and covered under the seat cloth, or it can be arranged on the seat cloth. For example, in a baby carrier safety seat, a support cushion (or headrest) is generally provided at the upper part of the backrest to support the baby's head and protect the head to improve safety. The buffer structure can be arranged in the support cushion.

[0067] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0068] like Figure 1As shown, the present invention provides a fireproof buffer structure 41, which is mainly used in child safety seats. The fireproof buffer structure 41 includes a buffer plate 411 and a fireproof plate 412 attached to the buffer plate 411, wherein the buffer plate 411 is made of soft material and has good buffering and shock absorption performance, so that the head of the infant can be prevented from being subjected to excessive impact force in the event of an accident, and the burning rate of the fireproof plate 412 is lower than the burning rate of the buffer plate 411, so when a fire occurs, the burning rate of the overall cross-section of the buffer plate 411 and the fireproof plate 412 is lower than the burning rate when only the buffer plate 411 is set. The buffer plate 411 is a foam plate made of materials such as PU (polyurethane), EPP, EPS or EPE.

One side of the fireproof plate 462 and the first auxiliary fireproof plate 463 are respectively attached to the front and back sides of a buffer plate 461, and the other two buffer plates 461 are respectively attached to the other side of the fireproof plate 462 and the other side of the first auxiliary fireproof plate 463.

[0075] Reference Figure 7 The fireproof buffer structure 47 of the seventh embodiment is a three-layer structure, and includes a buffer plate 471, a fireproof plate 472 and a first auxiliary fireproof plate 473. One side of the fireproof plate 472 is attached to the buffer plate 471, and the first auxiliary fireproof plate 473 is attached to the other side of the fireproof plate 472. The following embodiments eight and nine are based on the present embodiment and further add other layers of structure.

[0076] Reference Figure 8 The eighth embodiment of the present invention is shown. The fireproof buffer structure 48 of this embodiment includes two buffer plates 481, a fireproof plate 482, and a first auxiliary fireproof plate 483. One side of the fireproof plate 482 is attached to a buffer plate 481, one side of the first auxiliary fireproof plate 483 is attached to the other side of the fireproof plate 482, and the other buffer plate 481 is attached to the other side of the first auxiliary fireproof plate 483.

[0077] Fig. 9 The ninth embodiment of the present invention is shown in FIG. 4 , in which the fireproof buffer structure 49 comprises two buffer plates 491, a fireproof plate 492, a first auxiliary fireproof plate 493 and a second auxiliary fireproof plate 494. The fireproof plate 492 and the first auxiliary fireproof plate 493 are attached to each other and are located between one side of the two buffer plates 491, while the second auxiliary fireproof plate 494 is attached to the other side of one of the buffer plates 491.

[0078] Fig.10 The fireproof buffer structure 40 in the tenth embodiment of the present invention is a five-layer structure, and includes two buffer plates 401 and a fireproof plate 402, a first auxiliary fireproof plate 403, and a second auxiliary fireproof plate 404. One side of the fireproof plate 402 is attached to one buffer plate 401, one side of the first auxiliary fireproof plate 403 is attached to the other side of the fireproof plate 402, one side of the second auxiliary fireproof plate 404 is attached to the other side of the first auxiliary fireproof plate 403, and another buffer plate 401 is attached to the other side of the second auxiliary fireproof plate 404.

[0079] In the above second to tenth embodiments, the buffer board is the same foam board as in the first embodiment, and the fireproof board, the first auxiliary fireproof board, and the second auxiliary fireproof board are boards made of PE, PP, EPS, EPP, EPO, fireproof foam, EVA or plant cotton, and the burning rate of the first auxiliary fireproof board and the second auxiliary fireproof board is lower than that of the buffer board. In embodiments three to six, two or three of the fireproof board, the first auxiliary fireproof board, and the second auxiliary fireproof board can be the same material or different materials. In embodiments seven, eight, and nine, the fireproof board and the first auxiliary fireproof board are different materials. The second auxiliary fireproof board 494 in embodiment nine can be the same as one of the fireproof board 492 or the first auxiliary fireproof board 493, or different from both. In the tenth embodiment, the fireproof board 402 and the second auxiliary fireproof board 404 are different from the materials of the first auxiliary fireproof board 403, and the fireproof board 402 and the second auxiliary fireproof board 404 can be the same or different. By adjusting the materials of several fireproof boards, the burning speed of the fireproof buffer structure as a whole can be adjusted. In addition, the texture of the fireproof board is generally harder than the buffer board, which can transfer the impact force to the entire buffer board in the event of a collision, so that the buffer board deforms evenly, thereby achieving a better buffering effect.

[0080] like Fig.11 As shown, the present invention also provides a safety seat 8 provided with a fireproof buffer structure 50, the fireproof buffer structure 50 is directly attached to the safety seat 8, and the attachment position can be one or more of the seat 81, the side 82 or the backrest 83, the headrest 84, etc. of the safety seat 8, and the specific shape of the fireproof buffer structure 50 depends on the position where it is set, and can be a long strip, square or round, etc. The fireproof buffer structure 50 can be any one of the above embodiments one to ten. Moreover, when one of the outermost plates of the fireproof buffer structure 50 is a fireproof board, the fireproof board is closer to the center of the safety seat 8 than the buffer board attached to it or adjacent to it, that is, the buffer board is located between the inner side of the safety seat 8 and the fireproof board, and the fireproof board is in contact with the child. The following will describe in detail the setting direction of the fireproof buffer structure in the above embodiments one, three, seven, and nine.

[0081] like Fig.12As shown, the fireproof buffer structure 41 is arranged on the inner side of both sides of the headrest 84, wherein the fireproof plate 412 is closer to the center of the headrest 84 than the buffer plate 411, and the buffer plate 411 is located between the inner side of the headrest 84 and the fireproof plate 412. Figures 13 to 15 The first auxiliary fire protection plates 433, 473 and the second auxiliary fire protection plates 494 of the fire protection buffer structures 43, 47 and 49 are located closer to the center of the headrest 84, and the buffer plates 431, 471 and 791 of the fire protection buffer structures 43, 47 and 49 are located between the inner side of the headrest 84 and the first auxiliary fire protection plates 433, 473 and the second auxiliary fire protection plates 494, respectively.

[0082] like Fig.16 As shown, another safety seat 3 provided by the present invention includes a seat body 31 and a support cushion device 1 arranged in the seat body 31, and the support cushion device 1 is used as a headrest to support the head of an infant. The support cushion device 1 is provided with the fireproof buffer structure of the present invention and provides safety protection for the head.

[0083] Combination Fig.17 , Fig.18 The support cushion device 1 includes a covering 11 and a fireproof buffer structure 45 contained in the covering 11. The fireproof buffer structure 45 is the structure in the fifth embodiment described above, including a buffer plate 451 and a fireproof plate 452 and a first auxiliary fireproof plate 453 attached to both sides of the buffer plate 451. The covering 11 includes a headrest portion 111 and two wings 112 connected to both sides of the headrest portion 111. When an infant is riding in a vehicle, the head rests on the headrest portion 111. Each wing portion 112 contains the above-mentioned fireproof buffer structure 45, so that the two wings 112 form protection on both sides of the head. Specifically, a receiving pocket 113 is provided in the wing portion 112. The receiving pocket 113 has an opening, and the fireproof buffer structure 45 is placed into the receiving pocket 113 through the opening. The shape of the fireproof buffer structure 45 corresponds to the shape of the wing 112 and the receiving pocket 113, and the size is slightly smaller than the receiving pocket 113. After being sealed in the receiving pocket 113, there will be no excessive displacement in the wing 112. In addition, the headrest portion 111 of the covering 11 can also accommodate the fireproof buffer structure 45. For example, in another embodiment of the present invention, the headrest portion 111 and the wing 112 of the covering 11 both accommodate the fireproof buffer structure 45; in another embodiment of the present invention, the fireproof buffer structure 45 is accommodated only in the headrest portion 111, and the fireproof buffer structure 45 is not provided in the wing 112.

[0084] In addition, since the hardness of the fireproof board 452 made of PE material is higher than that of the buffer board 451, in order to avoid discomfort to infants and young children, a soft filler (not shown) can be arranged on the fireproof board 452 in the wing 112. An interlayer is arranged on the outside of the receiving pocket 113 in the wing 112, and the filler is filled in the interlayer. Of course, the filler can also be directly filled into the receiving pocket 113 and cover the fireproof board 452, as long as it is ensured that the filler is located on the outside of the surface of the fireproof board 452. The filler is specifically made of foam made of PU, EPP, EPS or EPE material, or cotton and other materials that can increase comfort.

[0085] In addition to the fireproof buffer structure 45, the support pad device 1 may also accommodate other structures in the above-mentioned embodiments one to ten.

[0086] Compared with the prior art, the safety seats 3 and 8 of the present invention are provided with a fireproof buffer structure, which can improve the flame retardant effect during fire while achieving the buffer function, thereby achieving both safety and comfort.

[0087] The above disclosure is only a preferred embodiment of the present invention, which is to facilitate the understanding and implementation of the present invention by those skilled in the art. It certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
