Inflatable recliner

Abstract

An inflatable recliner includes an inflatable body and a side portion disposed beside the inflatable body. The inflatable body includes a backrest portion, and a buttock-and-leg support portion connected to the backrest portion. The side portion is extended backward and beyond where the backrest portion and the buttock-and-leg support portion are connected, thereby providing the inflatable body with a supporting force that prevents the inflatable recliner from being overturned.

What is claimed is: 
     
         1 . An inflatable recliner, comprising:
 an inflatable body comprising a backrest portion, and a buttock-and-leg support portion connected to the backrest portion;   a side portion disposed beside the inflatable body;   wherein the side portion is extended backward and beyond where the backrest portion and the buttock-and-leg support portion are connected, thereby providing the inflatable body with a supporting force that prevents the inflatable recliner from being overturned.   
     
     
         2 . The inflatable recliner as claimed in  claim 1 , wherein the side portion is an armrest. 
     
     
         3 . The inflatable recliner as claimed in  claim 1 , wherein the backrest portion is adjustable to slope with respect to the buttock-and-leg support by virtue of a concave space formed between the backrest portion and the buttock-and-leg support portion. 
     
     
         4 . The inflatable recliner as claimed in  claim 3 , wherein the concave space is a groove extending in a traverse direction of the inflatable recliner. 
     
     
         5 . The inflatable recliner as claimed in  claim 1 , further comprising a tensioning element which is connected to the buttock-and-leg support portion and the backrest portion to keep the backrest portion sloped with respect to the buttock-and-leg support portion at an angle. 
     
     
         6 . The inflatable recliner as claimed in  claim 5 , wherein the tensioning element is a buckle strap which comprises an adjustment device operated manually to adjust a length of the buckle strap so as to raise or lower the backrest portion. 
     
     
         7 . The inflatable recliner as claimed in  claim 6 , wherein the buckle strap comprises a first part connected to the buttock-and-leg support portion, a second part extended over the backrest portion and connected to the buttock-and-leg support portion, and a buckle configured to connect or disconnect the first part and the second part. 
     
     
         8 . The inflatable recliner as claimed in  claim 5 , further comprising a reel device wherein the tensioning element is a cord to be rolled by the reel device. 
     
     
         9 . The inflatable recliner as claimed in  claim 8 , wherein:
 the reel device comprises a rotary disk and a pawl disk;   the rotary disk comprises teeth;   the pawl disk comprises a pawl engaged with the teeth;   the teeth comprise gently sloped edges, and steeply sloped edges disposed opposite to the gently sloped edges;   the steeply sloped edges are configured to stop the rotary disk from rotating in a first direction in a way that the pawl catches against the steeply sloped edges;   the pawl slides over the gently sloped edges when the rotary disk is rotated in a second direction opposite to the first direction.   
     
     
         10 . The inflatable recliner as claimed in  claim 1 , further comprising two tensioning elements, wherein each of the tensioning elements is connected to the buttock-and-leg support portion and the backrest portion to keep the backrest portion sloped with respect to the buttock-and-leg support portion at an angle. 
     
     
         11 . The inflatable recliner as claimed in  claim 10 , wherein each of the tensioning elements is a buckle strap, the buckle strap comprises a first part connected to the buttock-and-leg support portion, a second part connected to the buttock-and-leg support portion, and a buckle configured to connect or disconnect the first part and the second part. 
     
     
         12 . An inflatable recliner, comprising:
 a backrest portion;   a buttock-and-leg support portion connected to the backrest portion;   wherein the buttock-and-leg support portion is extended backward at both sides of the backrest portion and beyond where the backrest portion and the buttock-and-leg support portion are connected, thereby providing the inflatable recliner with a supporting force that prevents the inflatable recliner from being overturned.   
     
     
         13 . The inflatable recliner as claimed in  claim 12 , wherein the backrest portion is adjustable to slope with respect to the buttock-and-leg support by virtue of a concave space formed between the backrest portion and the buttock-and-leg support portion. 
     
     
         14 . The inflatable recliner as claimed in  claim 13 , wherein the concave space is a groove extending in a traverse direction of the inflatable recliner. 
     
     
         15 . The inflatable recliner as claimed in  claim 12 , further comprising a tensioning element which is connected to the buttock-and-leg support portion and the backrest portion to keep the backrest portion sloped with respect to the buttock-and-leg support portion at an angle. 
     
     
         16 . The inflatable recliner as claimed in  claim 15 , wherein the tensioning element is a buckle strap. 
     
     
         17 . The inflatable recliner as claimed in  claim 16 , wherein the buckle strap comprises a first part connected to the buttock-and-leg support portion, a second part extended over the backrest portion and connected to the buttock-and-leg support portion, and a buckle configured to connect or disconnect the first part and the second part. 
     
     
         18 . The inflatable recliner as claimed in  claim 15 , further comprising a reel device wherein the tensioning element is a cord to be rolled by the reel device. 
     
     
         19 . The inflatable recliner as claimed in  claim 18 , wherein:
 the reel device comprises a rotary disk and a pawl disk;   the rotary disk comprises teeth;   the pawl disk comprises a pawl engaged with the teeth;   the teeth comprise gently sloped edges, and steeply sloped edges disposed opposite to the gently sloped edges;   the steeply sloped edges are configured to stop the rotary disk from rotating in a first direction in a way that the pawl catches against the steeply sloped edges;   the pawl slides over the gently sloped edges when the rotary disk is rotated in a second direction opposite to the first direction.   
     
     
         20 . The inflatable recliner as claimed in  claim 12 , further comprising two tensioning elements, wherein each of the tensioning elements is connected to the buttock-and-leg support portion and the backrest portion to keep the backrest portion sloped with respect to the buttock-and-leg support portion at an angle. 
     
     
         21 . The inflatable recliner as claimed in  claim 20 , wherein each of the tensioning elements is a buckle strap, the buckle strap comprises a first part connected to the buttock-and-leg support portion, a second part connected to the buttock-and-leg support portion, and a buckle configured to connect or disconnect the first part and the second part.
