Outdoor seat cushion for use with an elevated wild game observation stand, and observation stand including same
View Patent ↗A seat cushion, for use with an elevated outdoor hunting or observation stand, is constructed with a plurality of layers therein. The seat cushion is constructed in two or more layers in which one layer includes an envelope with a gas sealed therein. The envelope may include at least two independently sealed chambers. A second layer of the seat cushion includes a flexible foam pad above the envelope. The seat cushion may further include a reinforcing member below the envelope, which may be made of foam which is denser than the foam of the top foam layer. A portable tree seat apparatus is also described, including a frame, an attachment member for cooperating with the frame to attach the frame to a tree, and the multi-layer seat cushion.
1. A seat cushion for use with a tree seat apparatus, said seat cushion comprising:
a valveless, sealed envelope containing an entrapped gas;
a layer of flexible, resilient foam above the scaled envelope and defining a top foam layer;
a reinforcing member below the sealed envelope, said reinforcing member comprising a material which is denser than the foam of the top foam layer; and
a protective outer layer substantially surrounding and enclosing the sealed envelope, the top foam layer, and the reinforcing member;
wherein said envelope extends over an area which substantially covers said reinforcing member, wherein the reinforcing member is more than twice as thick as the outer layer.
2. The seat cushion of claim 1 , wherein said outer layer comprises a fabric material.
3. The seat cushion of claim 1 , wherein the reinforcing member comprises a resilient closed cell foam.
4. The seat cushion of claim 3 , wherein the sealed envelope comprises at least two separate chambers.
5. The seat cushion of claim 1 , wherein the sealed envelope comprises at least two separate chambers.
6. The tree seat apparatus of claim 1 , wherein the sealed envelope has a flexible resilient foam material therein.
7. The tree seat apparatus of claim 1 , wherein the sealed envelope is substantially horizontally coextensive with the top foam layer.
8. The seat cushion of claim 1 , further comprising straps attached to the protective outer layer for removably attaching the cushion to a support member of a tree seat.
9. A tree seat apparatus, comprising
a frame comprising a seat support member,
an attachment member which is operatively connectable to the frame for removably attaching the frame to a tree, and
a seat cushion for operatively attaching to said seat support member and comprising:
a valveless sealed envelop, containing an entrapped gas;
a layer of flexible, resilient foam above the sealed envelope and defining a top foam layer;
a reinforcing member comprising a foam material, said reinforcing member being situated below the sealed envelope and formed from a foam which is denser than the top foam layer; and
a protective outer layer covering the reinforcing member, the sealed envelope and the top foam layer;
wherein the reinforcing member is more than twice as thick as the outer layer.
10. The tree seat apparatus of claim 9 , wherein the seat cushion outer layer comprises a fabric material.
11. The tree seat apparatus of claim 9 , wherein the seat cushion outer layer comprises a water-resistant liner.
12. The tree seat apparatus of claim 9 , wherein the attachment member comprises at least one restraining device selected from the group consisting of belts, cables and chains.
13. The tree seat of claim 9 , wherein the sealed envelope comprises at least two separate chambers.
14. A seat cushion for use with an outdoor seat apparatus, said seat cushion comprising:
a valveless, sealed envelope containing an entrapped gas;
a layer of flexible, resilient foam disposed above the sealed envelope and defining a top foam layer;
a reinforcing member below the sealed envelope, said reinforcing member formed from a flexible, resilient foam which is denser than the foam of the top foam layer; and
a protective outer layer substantially surrounding and enclosing the sealed envelope, the top foam layer, and the reinforcing member;
wherein the sealed envelope, the reinforcing member and the top foam layer are all substantially horizontally coextensive with one another, wherein the reinforcing member is more than twice as thick as the outer layer.
15. The seat cushion of claim 14 , further comprising straps attached to the protective outer layer for removably attaching the cushion to a support member of a tree seat.
