Tree seat apparatus with a seat cushion having a sealed envelope therein

Abstract

A portable tree seat apparatus includes a frame, an attachment member for cooperating with the frame to attach the frame to a tree, and a seat cushion. The seat cushion is constructed in two or more layers in which one layer includes an air pillow having a hollow envelope with a gas sealed therein. Preferably, the air pillow includes at least two independently sealed chambers. An optional second layer of the seat cushion includes a flexible foam pad.

Having, thus, described the invention, what is claimed is:  
     
         1 . A tree seat/tree stand apparatus, comprising: 
 a frame,    an attachment member for attaching the frame to a tree, and    a seat cushion comprising a hollow envelope with a gas sealed therein.    
     
     
         2 . The tree seat apparatus of  claim 1 , wherein the seat cushion includes at least two adjacent chambers, and wherein each of the chambers is independently sealed.  
     
     
         3 . The tree seat apparatus of  claim 1 , wherein the hollow cushion has a flexible foam therein.  
     
     
         4 . The tree seat apparatus of  claim 1 , wherein the seat cushion further comprises a layer of foam material below the hollow envelope.  
     
     
         5 . The tree seat apparatus of  claim 1 , wherein the seat cushion further comprises a layer of foam material above the hollow envelope.  
     
     
         6 . A tree seat apparatus, comprising: 
 a frame, comprising: 
 at least one connector bar for substantially vertical placement against a tree trunk;  
 a foot rest operatively attached to the connector bar; and  
 a seat support member operatively attached to the connector bar and spaced away from the foot rest;  
   an attachment member which is operatively connectable to the frame for removably attaching the frame to a tree; and    a seat cushion comprising: 
 a sealed envelope containing an entrapped gas;  
 a reinforcing member below the sealed envelope; and  
 a protective outer layer covering the sealed envelope and the reinforcing member.  
   
     
     
         7 . The tree seat apparatus of  claim 6 , wherein the seat outer layer comprises a fabric material.  
     
     
         8 . The tree seat apparatus of  claim 6 , wherein the seat further comprises a layer of flexible, resilient foam above the sealed envelope.  
     
     
         9 . The tree seat apparatus of  claim 6 , wherein the attachment member comprises at least one restraining device selected from the group consisting of belts, cables and chains.  
     
     
         10 . The tree seat apparatus of  claim 6 , wherein the sealed envelope comprises at least two separate chambers.  
     
     
         11 . The tree seat apparatus of  claim 6 , wherein the sealed envelope has a flexible resilient foam material therein.  
     
     
         12 . A tree seat apparatus, comprising 
 a frame,    an attachment member which is operatively connectable to the frame for removably attaching the frame to a tree, and    a seat cushion comprising: 
 a sealed envelope containing an entrapped gas;  
 a layer of flexible, resilient foam above the sealed envelope; and  
 a protective outer layer covering the sealed envelope and the flexible foam layer.  
   
     
     
         13 . The tree seat apparatus of  claim 12 , wherein the seat cushion outer layer comprises a fabric material.  
     
     
         14 . The tree seat apparatus of  claim 12 , wherein the seat cushion outer layer comprises a water-resistant liner.  
     
     
         15 . The tree seat apparatus of  claim 12 , wherein the attachment member comprises at least one restraining device selected from the group consisting of belts, cables and chains.  
     
     
         16 . The tree seat of  claim 12 , wherein the sealed envelope comprises at least two separate chambers.
