Ergonomic dual-purpose pillow for back sleeping and side sleeping

Abstract

An ergonomic dual-purpose pillow for back sleeping and side sleeping includes breathable pores and elastic support columns spaced from one another and disposed at the middle of the thickness of the pillow. The quantity, width, arrangement density or height of each breathable pore and/or elastic support column can be adjusted to let the supporting force fed back by a central support section of the pillow be smaller than that of the two side support sections of the pillow, so as to overcome the central recession of the conventional pillow that is likely to cause the head to slip off and leads to sleep problems.

What is claimed is: 
     
         1 . An ergonomic dual-purpose pillow for back sleeping and side sleeping, comprising a plurality of breathable pores spaced from one another and disposed at the middle of the thickness of the pillow, and an elastic support column formed between every two adjacent breathable pores; wherein the plurality of elastic support columns are disposed at the middle of the pillow to constitute a central support section capable of supporting the back of the neck and the back of the head of a user, so that both sides of the pillow separately constitute a side support section capable of stably supporting both sides of the head of the user, and the quantity, the width, the arrangement density or the height of each breathable pore and/or each elastic support column are adjustable to let the supporting force fed back by the central support section be smaller than the supporting force fed back by the side support section, so that regardless of back sleeping or side sleeping, the cervical spine of the user substantially conforms to the natural curve when no force is exerted and the pillow also conforms to ergonomics. 
     
     
         2 . The ergonomic dual-purpose pillow for back sleeping and side sleeping as claimed in  claim 1 , wherein the pillow comprises a plurality of breathable pores and elastic support columns spaced from one another and disposed in positions of the thickness of the pillow relative to the two side support sections, and the quantity, width, arrangement density or height of each breathable pore and/or elastic support column can be adjusted to let the supporting force fed back by the central support section be smaller than the supporting force fed back by the side support section. 
     
     
         3 . The ergonomic dual-purpose pillow for back sleeping and side sleeping as claimed in  claim 2 , wherein the plurality of breathable pores are configured to be longitudinally or transversally parallel to one another or in a dox matrix arrangement on the pillow. 
     
     
         4 . The ergonomic dual-purpose pillow for back sleeping and side sleeping as claimed in  claim 3 , wherein the pillow is integrally formed, or comprised of a lower pad, and an upper pad stacked on the top surface of the lower pad, and the top of the upper pad is an outer layer provided for lying a user's head on the pillow. 
     
     
         5 . The ergonomic dual-purpose pillow for back sleeping and side sleeping as claimed in  claim 4 , wherein the plurality of breathable pores are comprised of a plurality of parallel cut grooves formed on the bottom surface or the top surface of the upper pad and/or the lower pad to constitute the central support section and two side support sections respectively after the upper pad is stacked on the lower pad. 
     
     
         6 . The ergonomic dual-purpose pillow for back sleeping and side sleeping as claimed in  claim 5 , wherein the plurality of cut grooves of the central support section and the plurality of cut grooves of the two side support sections are staggered r and disposed on the corresponding stacked surfaces of the upper pad and the lower pad respectively. 
     
     
         7 . The ergonomic dual-purpose pillow for back sleeping and side sleeping as claimed in  claim 5 , wherein the upper pad has an upper recession or a lower protrusion formed at the middle of the bottom surface of the upper pad, and the lower pad has an upper protrusion or a lower recession formed at the top surface of the middle of the lower pad and engaged with one another respectively. 
     
     
         8 . The ergonomic dual-purpose pillow for back sleeping and side sleeping as claimed in  claim 7 , wherein the plurality of cut grooves and elastic support columns configured to be corresponsive to the central support section of the pillow are disposed on the bottom surface of the lower protrusion or the top surface of the upper protrusion of the upper pad or the lower pad. 
     
     
         9 . The ergonomic dual-purpose pillow for back sleeping and side sleeping as claimed in  claim 7 , wherein the pillow further comprises an auxiliary pad stacked onto the front of the upper pad, and the top surface or the bottom surface on both sides of the auxiliary pad has a plurality of parallel cut grooves, so that a neck support section is formed at the middle of the auxiliary pad and configured to be corresponsive to a human cervical spine. 
     
     
         10 . The ergonomic dual-purpose pillow for back sleeping and side sleeping as claimed in  claim 9 , wherein both sides of the outer layer relative to the top surface of the side support section are configured to be facing the central support section and tilted downwardly.
