[0054] The sacrum support 10 is connected between the seat back 20 and the seat cushion 30 through the first connecting part 13 and the second connecting part 14; when the seat back 20 adjusts the posture, the wrapping skin 11 will deform under the extrusion or stretching, and the filler 12 inside will be compressed or restored with the deformation of the wrapping skin 11 to effectively support the sacrum of the passenger in the process of adjusting the seat back 20, so as to realize the support continuity of the seat back 20 to the sacrum at the lower end of the passenger's back, and improve the comfort of the passenger. Figures 3 to 5

[0055] Please refer to Figure 1 ​In some embodiments, the wrapping skin 11 comprises a wrapping outer skin 111 and a wrapping inner skin 112 inside the wrapping outer skin 111, the wrapping outer skin 111 and the wrapping inner skin 112 are curved towards the same direction, a first end 1111 of the wrapping outer skin 111 and a first end 1121 of the wrapping inner skin 112 are connected to form a first connecting part 13, and a second end 1112 of the wrapping outer skin 111 and a second end 1122 of the wrapping inner skin 112 are connected to form a second connecting part 14.

[0056] The filling 12 is filled between the wrapping outer skin 111 and the wrapping inner skin 112.

[0057] The wrapping outer skin 111 and the wrapping inner skin 112 are curved towards the same direction, which can be understood as, after the sacrum support 10 is connected between the seat back 20 and the seat cushion 30, the wrapping outer skin 111 and the wrapping inner skin 112 are both curved towards the sacrum at the lower end of the passenger's back. In this way, the wrapping skin 11 can provide better support to the passenger through the filling 12, and will not invade the passenger space of the rear row due to excessive deformation.

[0058] The first connecting part 13 and the second connecting part 14 are arranged in a spaced manner.

[0059] The first end 1111 of the wrapping outer skin 111 and the first end 1121 of the wrapping inner skin 112 are connected to form the first connecting part 13, that is, the first end 1111 and the first end 1121 are both arranged along a direction perpendicular to the paper surface, and the first end 1111 and the first end 1121 are connected to form a first connecting part 13. Figure 1

[0061] The second end 1112 of the wrapping outer skin 111 and the second end 1122 of the wrapping inner skin 112 are connected to form the second connecting part 14, that is, the second end 1112 and the second end 1122 are both arranged along a direction perpendicular to the paper surface, and the second end 1112 and the second end 1122 are connected to form a second connecting part 14. Figure 1

[0062] Optionally, the second end 1122 is inside the second end 1112. Of course, the second end 1122 can also be outside the second end 1112, that is, the second end 1122 is folded outside the second end 1112 from the inside of the second end 1112. ​​

[0063] Based on the above scheme, the filler 12 can be filled in the package skin 111 first, and then the package lining 112 is connected to the package skin 111, which is beneficial to the filling of the filler 12.

[0064] In other embodiments, referring to Figure 2 , the package skin 11 can be an integral whole. After the filler 12 is filled in the package skin 11, the first end and the second end of the package skin 11 can be connected, and at this time, the opposite sides of the package skin 11 respectively constitute the first connecting part 13 and the second connecting part 14.

[0065] Please refer to Figure 1 , in some embodiments, the skin first end 1111 of the package skin 111 and the lining first end 1121 of the package lining 112 are sewn together, and the first connecting part 13 is a first sewn edge; the skin second end 1112 of the package skin 111 and the lining second end 1122 of the package lining 112 are sewn together, and the second connecting part 14 is a second sewn edge.

[0066] That is, after the filler 12 is filled between the package skin 111 and the package lining 112, the skin first end 1111 and the lining first end 1121 are overlapped and sewn together, and the skin second end 1112 and the lining second end 1122 are overlapped and sewn together.

[0067] Wherein, when the sacrum support 10 is connected between the seat back 20 and the seat cushion 30, the first sewn edge can be sewn on the seat back 20, or the second sewn edge can be sewn on the seat cushion 30.

[0068] Based on the above scheme, the package skin 111 and the package lining 112 are sewn together, so that their connection is more reliable, so that the filler 12 is not easy to run out of the package skin 11.

[0069] In other embodiments, in the case that the skin first end 1111 of the package skin 111 and the lining first end 1121 of the package lining 112 are sewn together, the skin second end 1112 of the package skin 111 and the lining second end 1122 of the package lining 112 can be connected by Velcro, zipper, etc.; or, in the case that the skin second end 1112 of the package skin 111 and the lining second end 1122 of the package lining 112 are sewn together, the skin first end 1111 of the package skin 111 and the lining first end 1121 of the package lining 112 can be connected by Velcro, zipper, etc.; or, the skin first end 1111 of the package skin 111 and the lining first end 1121 of the package lining 112 can be connected by Velcro, zipper, etc., and the skin second end 1112 of the package skin 111 and the lining second end 1122 of the package lining 112 can also be connected by Velcro, zipper, etc.

[0073] In some embodiments, the wrapping inner lining 112 is an elastic cloth. The elastic cloth is usually made of elastic fibers (such as spandex and lycra) and other fibers (such as cotton and polyester). These materials give the cloth good stretchability and softness to better adapt to the length of the wrapping inner lining 112 at different angles of the seat back 20.

[0074] In other embodiments, the wrapping inner lining 112 can also be a non-woven fabric, a fabric, and the like.

[0075] In some embodiments, the filler 12 is a sponge. For example, the sponge can be a memory sponge made of polyurethane foam material, which has good elasticity and air permeability and is suitable for long sitting conditions. Of course, the filler 12 can also be polyethylene foam (i.e., pearl wool); or the filler 12 can also be PP cotton, also known as doll cotton, hollow cotton, and filling cotton.

[0076] In some embodiments, the filler 12 is latex. For example, the latex can be natural latex, which has excellent comfort and air permeability. The latex is soft and elastic and can effectively support the passenger's sacrum.

[0087] Please refer to Figure 3 In some embodiments, a gap 40 is left between the seat back 20 and the seat cushion 30.

[0088] Before the sacrum support 10 is arranged, the matching between the seat back 20 and the seat cushion 30 needs to meet the requirement of no gap, but since the seat cushion 30 and the seat back 20 are soft parts, the size tolerance distribution range is large, so the seat cushion 30 and the seat back 20 often need to keep a certain interference to avoid the gap; in this interference state, the surface fabric of the seat cushion 30 and the seat back 20 will produce friction noise during the adjustment of the seat back 20. After the sacrum support 10 is arranged between the seat back 20 and the seat cushion 30, although there is a gap 40 between the seat back 20 and the seat cushion 30, the sacrum support 10 can also block the gap 40 to avoid the gap between the seat back 20 and the seat cushion 30, thereby avoiding the problem of articles falling into the gap 40; at the same time, during the adjustment of the seat back 20, the sliding between the seat back 20 and the seat cushion 30 becomes the rolling between the seat back 20 and the sacrum support 10 and between the seat cushion 30 and the sacrum support 10, which improves the problem of friction noise.

[0089] The third aspect of the present application provides an automobile, which comprises the automobile seat 100 according to the second aspect.

[0090] The automobile adopts any one or more of the above-mentioned embodiments of the automobile seat 100, and thus has the beneficial effects of the above-mentioned embodiments, which will not be repeated here.

[0091] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application.
