Description

Technical Field

[0001] This utility model relates to the field of backrest pillows, and in particular to a backrest pillow that combines comfort and support. Background Technology

[0002] With the development of technology, in addition to traditional materials such as cotton, linen, and down, backrest pillows now feature new materials like memory foam, latex, and space foam. These materials offer better support, breathability, and comfort, better meeting people's needs for comfort during long periods of sitting. Without proper support, the lumbar spine loses its normal physiological curvature, leading to excessive bending or straightening, thus increasing pressure on the intervertebral discs. Backrest pillows fill the gap between the lower back and the chair back or sofa, providing strong support for the lumbar spine and maintaining its natural forward curvature.

[0003] Traditional cushions typically use a single material, such as pure cotton, latex, or memory foam. However, these materials have limitations in providing comfort and support. For example, while pure cotton cushions are soft and comfortable, they lack sufficient support; while latex or memory foam cushions offer better support, they are less breathable and soft. Utility Model Content

[0004] In view of this, the present invention provides a pillow that combines comfort and support, combining the advantages of high-elasticity sponge pillows and cotton pillows to meet the user's dual needs for comfort and support.

[0005] A comfortable and supportive pillow includes a pillow core and a pillowcase covering the outside of the pillow core. The pillow core includes an inner pillow core and an outer pillow core that wraps around the inner pillow core. The inner pillow core includes a pillow surface. The pillow surface includes a lumbar support surface and a back support surface connected to the lumbar support surface. The lumbar support surface is configured as an arc-shaped surface convex towards the outer pillow core, and the back support surface is configured as an arc-shaped surface convex inwards. The height of the back support surface is lower than the height of the lumbar support surface. The outer pillow core is arranged in a ring shape with its ends connected. The pillowcase covers the outer pillow core, providing protection and aesthetic appeal.

[0006] Furthermore, the inner pillow core also includes a plane disposed relative to the pillow surface, which enables the inner pillow core to form stable support with the bed or other supporting structure.

[0007] Furthermore, the outer pillow core is fixedly attached to the outer side of the inner pillow core by sewing or gluing.

[0008] Furthermore, the thickness of the outer pillow core on the side facing the pillow surface is greater than its thickness on the side opposite to the pillow surface.

[0009] Furthermore, the pillowcase is equipped with a zipper as an opening for taking out and putting in the inner and outer pillow cores.

[0010] Furthermore, the pillowcase is woven by machine, and its surface has a mesh pattern made of warp and weft threads.

[0011] Compared with existing technologies, this utility model provides a pillow that combines comfort and support, consisting of an inner pillow core and an outer pillow core. The inner pillow core provides support, while the outer pillow core provides comfort, satisfying the user's dual needs for comfort and support. The inner pillow core has a lumbar support surface and a back support surface. The lumbar support surface is an arc-shaped surface that bulges towards the outer pillow core, while the back support surface is an arc-shaped surface that bulges inward. The height of the back support surface is lower than that of the lumbar support surface, allowing the pillow surfaces to conform to the user's lumbar and back curves, providing comfortable support. The outer pillow core provides a comfortable tactile experience. Attached Figure Description

[0016] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0017] Please see Figures 1 to 3 This is a structural diagram of a cushion that combines comfort and support, provided by this utility model. The cushion includes a pillow core 10 and a pillowcase 20 fitted over the outside of the pillow core 10. It is conceivable that the cushion may also include other functional modules, such as zippers, which are technologies known to those skilled in the art and will not be described in detail here.

[0018] like Figure 2 , 3As shown, the pillow core 10 includes an inner pillow core 11 and an outer pillow core 12 that wraps around the inner pillow core 11.

[0019] The inner pillow core 11 includes a pillow surface 111 and a plane 112 disposed opposite to the pillow surface 111. The inner pillow core 11 is made of polyurethane foam, preferably high-density polyurethane foam. High-density polyurethane foam has strong resilience, which allows the inner pillow core 11, as the main support part of the pillow, to provide stable support according to the pressure applied to the waist and back of the human body, and to quickly return to its initial shape after the pressure is released.

[0020] The pillow surface 111 includes a lumbar pillow surface 1111 and a back pillow surface 1112 connected to the lumbar pillow surface 1111.

[0021] The lumbar support surface 1111 and the back support surface 1112 form a complete pillow surface 111. The lumbar support surface 1111 is configured as an arc surface that protrudes towards the outer pillow core 12. The lumbar support surface 1111 is used to fill the gap between the user's waist and the support such as the chair back or sofa when the user is sitting, providing support for the user's waist, reducing excessive tension in the waist muscles and joints, reducing the risk of muscle fatigue and joint wear, and thus alleviating the fatigue caused by prolonged sitting.

[0022] The back pillow surface 1112 is designed as an inwardly convex arc surface. The shape of the back pillow surface 1112 is designed according to the shape of the back of the human head, and the back pillow surface 1112 is used to provide support for the user's back. The height of the back pillow surface 112 is lower than the height of the lumbar pillow surface 1111, so as to avoid the user's back support height being higher than the lumbar support height, allowing the user's back and waist to be in a relaxed state.

[0023] The plane 112 is oriented towards the support such as the chair back or sofa. By increasing the contact area, the support such as the chair back or sofa can form a stable support with the inner pillow core 11, without affecting the support effect of the pillow surface 111 on the user's waist and back.

[0024] The outer pillow core 12 is arranged in a ring shape with its ends connected. The outer pillow core 12 is fixedly attached to the outer side of the inner pillow core 11 by sewing or gluing. The thickness of the outer pillow core 12 on the side facing the pillow surface 111 is greater than its thickness on the side opposite the pillow surface 111, providing a comfortable feel for the user's back. The shape of the outer pillow core 12 is constrained by the shape of the pillowcase 20. The firmness of the outer pillow core 12 is less than that of the inner pillow core 11. The outer pillow core 12 is made of cotton.

[0025] like Figure 1As shown, the pillowcase 20 is mechanically woven, with a mesh pattern of warp and weft threads on its surface. The pillowcase 20 wraps around the outer pillow core 12, providing protection and aesthetic appeal. The pillowcase 20 is equipped with a zipper as an opening for taking in and removing the inner and outer pillow cores 11 and 12.

[0026] Compared with existing technologies, this utility model provides a pillow that combines comfort and support, consisting of an inner pillow core 11 and an outer pillow core 12. The support provided by the inner pillow core 11 and the comfort provided by the outer pillow core 12 satisfy the user's dual needs for comfort and support. The inner pillow core 11 has a lumbar support surface 1111 and a back support surface 1112. The lumbar support surface 1111 is an arc surface convex towards the outer pillow core 12, and the back support surface 1112 is an arc surface convex inward. The height of the back support surface 1112 is lower than the height of the lumbar support surface 1111, so that the pillow surface 111 is designed to conform to the user's lumbar and back curve, providing comfortable support. The outer pillow core 12 provides a comfortable tactile experience for the user.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
