Abstract
A void or space filling assembly designed to be used in combination with a chair structure of the type having a reclining backrest and normally found in airplane or ground travel vehicles as well as other permanent locations where such chair structures are desirable. The assembly includes a resilient, flexible material bladder which is expandable, upon being at least partially filled with fluid. The bladder is located on the chair structure adjacent the junction between the backrest and seat portion thereof and is specifically disposed and dimensioned to extend in filling and/or covering relation to any spacing or void normally existing at the junction of the backrest and seat portion when the backrest is disposed into its reclined position. The disposition of the bladder in this space filling position will allow for the seat portion, bladder and backrest to collectively define a substantially continuous support surface on which persons can comfortably recline and thereby avoid the discomfort of any significant voids or spaces in the reclining surface.
