Ergonomic sleeping mat

Abstract

The present invention discloses an ergonomic sleeping mat, which comprises a sleeping mat body including a sleeping mat layer and a ground mat layer fixedly connected with each other to form into one piece, thereby forming a closed accommodation cavity therebetween. A plurality of tensioning bands spaced from each other along a longitudinal direction is arranged within the closed accommodation cavity. An upper end of each tensioning band is fixedly bonded to the sleeping mat layer, while a lower end thereof is fixedly bonded to the ground mat layer, thereby dividing the closed accommodation cavity into a plurality of inflatable cavities extending along a lateral direction. The sleeping mat layer comprises an upper body portion, a waist portion and a lower limb portion corresponding to different parts of the human body, respectively. The tensioning bands corresponding to different portions of the sleeping mat layer are configured to have different heights. When the inflatable cavities are in an inflated state, each portion of the sleeping mat layer forms a contact surface that fits a corresponding part of the human body. The waist portion is configured to be thicker than the upper body portion, so that the waist portion is in contact with and supports the waist of the human body.

         4 . The ergonomic sleeping mat according to  claim 1 , wherein the upper end and the lower end of each tensioning band are fixedly bonded to the sleeping mat layer and the ground mat layer through face-to-face connection, respectively, each tensioning band presenting a C-shaped configuration in the inflated state. 
     
     
         5 . The ergonomic sleeping mat according to  claim 1 , wherein the lower limb portion comprises a hip region and a leg region that fit corresponding parts of the human body. 
     
     
         6 . The ergonomic sleeping mat according to  claim 1 , wherein the upper body portion comprises a neck region and a back region that fit corresponding parts of the human body. 
     
     
         7 . The ergonomic sleeping mat according to  claim 6 , wherein the lower limb portion comprises a leg region and an ankle region that fit corresponding parts of the human body. 
     
     
         8 . The ergonomic sleeping mat according to  claim 7 , wherein along the lateral direction, the tensioning bands corresponding to the neck region, the back region, the waist region and the ankle region are fixedly bonded to the sleeping mat layer and the ground mat layer in a continuous manner, so that protruding strips extending continuously along the lateral direction are formed in corresponding regions of the sleeping mat layer. 
     
     
         9 . The ergonomic sleeping mat according to  claim 8 , wherein the tensioning bands corresponding to the leg region and spaced from each other evenly along the lateral direction are fixedly bonded to the sleeping mat layer and the ground mat layer, so that undulating bulges extending along the lateral direction are formed in the leg region. 
     
     
         10 . The ergonomic sleeping mat according to  claim 8 , wherein the heights of the neck region, the waist region and the ankle region are configured to remain unchanged along the lateral direction. 
     
     
         11 . The ergonomic sleeping mat according to  claim 10 , wherein the height of the neck region is configured to be greater than a maximum height of the back region, so that the neck region forms a support for a head of the human body. 
     
     
         12 . The ergonomic sleeping mat according to  claim 1 , wherein height differences between undulating contact surfaces in corresponding regions of the sleeping mat layer are configured to be within a range between 0.5-4 cm. 
     
     
         13 . The ergonomic sleeping mat according to  claim 1 , wherein an inflation channel is provided within the closed accommodation cavity, so that the plurality of inflatable cavities is in communication with each other through the inflation channel, and the sleeping mat body is provided with an inflation port in communication with the inflation channel, for inflating all the inflatable cavities. 
     
     
         14 . The ergonomic sleeping mat according to  claim 12 , wherein an air pressure within the inflatable cavities after inflation is 2-5 kPa. 
     
     
         15 . The ergonomic sleeping mat according to  claim 7 , wherein a longitudinal spacing between adjacent tensioning bands corresponding to the neck region and the back region is configured as a first spacing, and a longitudinal spacing between adjacent tensioning bands corresponding to the waist region, the leg region and the ankle region is configured as a second spacing, wherein the second spacing is configured to be greater than the first spacing.
