[0044] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0045] Embodiment 1

[0046] See also Figure 1 and Figure 2, the structure of the backrest is shown in FIG. The backrest includes a resilient member 1 for covering the backrest bracket, a headrest 3 and a lumbar pillow 2. The headrest 3 is used to support the user's head, and the lumbar pillow 2 is used to support the user's waist and back. The lumbar pillow 2 is similar to an inverted trapezoid that is wide at the top and narrow at the bottom, and the surface is a curved surface that adapts to the shape of a person's waist and back.

[0047] See also Figure 3 The first embodiment of the soft back support structure of the present application is schematically shown. The soft back support structure includes a resilient member 1, which includes a first support area 11 adapted to the shape of the lumbar pillow 2. The resilient member 1 in this embodiment is a high-resilient sponge formed by molding.

[0048] See also Figure 4 The first support area 11 has a front side 111 facing the user and a back side 112 opposite to the front side 111 . The first support area 11 is a bilaterally symmetrical structure (in the direction shown in the view).

[0049] See also Figure 5 , the reverse side 112 has a first structure for increasing the displacement value of the first support area 11 after being subjected to force. The first structure in this embodiment is a plurality of transverse grooves 1121, and the cross-section of the transverse groove 1121 is one or a combination of rectangular, semicircular, triangular and elliptical shapes. The cross-section of the transverse groove 1121 in this embodiment is semicircular. According to the design requirements, the cross-sectional contour line of the transverse groove 1121 can also be composed of a plurality of straight lines and a plurality of curves, different straight lines or different curves, and the transverse groove 1121 is a central symmetrical structure or an axisymmetric structure. In some specific embodiments, if the rebound member 1 has a skeleton inside and it is not convenient to groove from the reverse side 111, a similar groove 1121 can also be opened on the front side 111, or a groove 1121 that runs through the front side 111 and the reverse side 112 can be directly opened. The groove 1121 can be cut by hand or directly molded.

[0050] See also Figure 6 , multiple transverse grooves 1121 extend transversely along the central axis of the first support area 11 shown by the center line in the figure and are arranged in a longitudinal interval. The multiple transverse grooves 1121 are arranged symmetrically along the central axis of the first support area 11 shown by the center line in the figure (in the direction shown in the figure). The spacing distances between the multiple transverse grooves 1121 can be the same, or they can be designed to be different distances according to the forces on different parts. The depth of the transverse grooves 1121 is generally not greater than half the thickness of the first support area 11.

[0051] The transverse groove 1121 can be formed integrally with the resilient member 1 by mold processing, or can be formed by cutting after the resilient member 1 is molded.

[0052] Embodiment 2

[0053] See also Figure 7 The difference between this embodiment and the first embodiment is that the first structure is a longitudinal groove 1122, and the plurality of longitudinal grooves 1122 extend longitudinally along the central axis direction of the first support area 11 shown by the center line in the figure and are arranged in a transverse interval, and the plurality of transverse grooves 1121 are arranged symmetrically along the central axis of the first support area 11 shown by the center line in the figure (direction shown in the figure).

[0054] Embodiment 3

[0055] See also Figure 8 The difference between this embodiment and the first and second embodiments is that the first structure includes staggered transverse grooves 1121 and longitudinal grooves 1122, and the transverse grooves 1121 and longitudinal grooves 1122 are symmetrical with respect to the central axis of the first support area 11. The first structure in this embodiment divides the back of the first support area 11 into different rectangular areas, and the different rectangular areas can be deformed separately, so that the first support area 11 can better adapt to the shape structure of different human waist and back and different sitting postures for balanced support.

[0056] The structural shapes of the transverse groove 1121 and the longitudinal groove 1122 in the above embodiments are only examples for facilitating the understanding of the technical solution. In actual design, different extension curves and cross-sectional shapes can be designed as needed, such as wavy lines, sawtooth lines, parabolas, hyperbolas and other layout structures.

[0057] Embodiment 4

[0058] See also Fig. 9 The soft support structure of the backrest of this embodiment is different from that of the first, second and third embodiments in that it also includes a second support area 12. The second support area 12 also has a front side 111 facing the user and a back side 112 opposite to the front side 111. The front side 111 has a second structure for increasing the displacement value of the support area and the flexible support member in direct contact with the support area after being compressed. The second structure is a plurality of pits 121 that are recessed from the front side 111 to the back side 112. The cross-section of the pits 121 is elliptical or rectangular. The arrangement of the pits 121 is symmetrical with respect to the central axis of the second support area 12 (in the direction shown in the view). Because the resilient member 1 is molded by high-resilient sponge molding, the thickness of the pits 121 in this embodiment can be designed to be the same as the thickness of other areas of the second support area 12.

[0059] The pit 121 can enhance the deformation of the second supporting area 12 and provide a deformation space for the headrest 3 after being subjected to pressure, so that the head has a softer experience, improves the user's comfort experience, and is more conducive to the relaxation of the head and neck.

[0060] Embodiment 5

[0061] See also Fig.10The difference between this embodiment and the fourth embodiment is that the second structure is a plurality of spherical pits 121, and the surface of the pits 121 is a hemispherical surface.
