Removable cushion-to-seating attachment with reusable PS adhesive

Abstract

For removable cushion-to-chair fastening, a region on the back side of the cushion is treated or covered with pressure sensitive adhesive (PSA) of sufficient gripping strength to hold the cushion in place without other support. The PSA element is an integral part of the cushion and allows the cushion to be reattached and readjusted multiple times, and can adhere to all manner of surfaces. The PSA material is of a type that can be washed with water and renewed or reactivated, regaining its full adhesive properties upon drying. A foldable rear flap may be provided that can be closed to cover the adhesive region and retained in the closed mode for storing, transporting and using the cushion in a conventional manner, and then opened and retained against the back panel in the open position for exposing the adhesive when the cushion is utilized in the open mode for chair-attachment. Alternatively, the closed mode could be implemented by a removable cover panel.

What is claimed is:  
     
         1 . An improved cushion attachment system for attaching a cushion to a chair, comprising: 
 a quantity of reusable pressure-sensitive adhesive applied to a selected rear region of the cushion, made and arranged to enable adjustable and removable attachment of the cushion to the chair.    
     
     
         2 . The improved cushion attachment system as defined in  claim 1  further comprising; 
 at least one cover flap, hingedly attached to the rear region of the cushion, made and arranged to provide two modes of deployment: an open mode wherein said pressure sensitive adhesive is caused to be exposed and thus available for attachment purposes while said flap is retained against a non-adhesive region of the back of the cushion, and a closed mode wherein said pressure sensitive adhesive is caused to be concealed by said flap and thus protected and unavailable for attachment purposes.  
 
     
     
         3 . The improved cushion attachment system as defined in  claim 1  further comprising; 
 at least one cover panel, removably attached to the rear region of the cushion and extending over the selected rear region treated with pressure sensitive adhesive, made and arranged to conceal and protect the pressure sensitive adhesive when not required for attachment purposes.  
 
     
     
         4 . An improved therapeutic back cushion for removable attachment to a chair, comprising: 
 an inflatable back cushion having a degree of inflation that can be readily adjusted by a user for cushioning effect;    a quantity of reusable pressure-sensitive adhesive applied to a selected rear region of the cushion, made and arranged to enable adjustable and removable attachment of the cushion to the chair.    
     
     
         5 . The improved therapeutic back cushion as defined in  claim 4  further comprising; 
 at least one cover flap, hingedly attached to the rear region of said back cushion, made and arranged to provide two modes of deployment: an open mode wherein said pressure sensitive adhesive is caused to be exposed and thus available for attachment purposes while said flap is retained against a non-adhesive rear region of said back cushion, and a closed mode wherein said pressure sensitive adhesive is caused to be concealed by said flap and thus protected and unavailable for attachment purposes.
