Abstract
The specification discloses a chair having a seat seated on spaced side rails above an auxiliary seat supporting surface which is spaced slightly below the seat and which shares the load imposed on the seat by a person sitting in it with the side rails and their supporting stretcher, yet allows the seat to give slightly so that the seat feels comfortably yielding.
Claims9
A chair comprising:
- a base having a central, upwardly extending supporting column;
- a structural, load supporting stretcher operably mounted on said column, said stretcher including struts projecting outwardly towards each side of said chair;
- a pair of spaced side rails joined to said struts of said stretcher;
- a rigid supporting seat seated on said side rails and spanning the space therebetween, said seat having only sufficient flexibility to flex slightly when a person using the chair sits on it, thereby giving the chair a comfortably yielding feeling;
- means securing said supporting seat to both said side rails;
- a seat support surface on said stretcher positioned below said seat and generally above support column of said base, said seat support surface being operably connected to said seat support column and there being a slight space between said supporting seat and said seat support surface whereby said seat flexes downwardly slightly when a person sits on it and comes to rest on said seat support surface such that said seat support surface transmits a portion of the load imposed on said seat directly downwardly to said supporting column, thereby decreasing the load which has to be carried by said side rails and said struts of said stretcher;
- said seat support surface on said stretcher comprises the top surface of said stretcher;
- said stretcher includes an upwardly protruding dome, protruding upwardly towards the bottom of said supporting seat, the top of said dome defining said seat supporting surface;
- sound deadening material is placed on top of said seat support surface whereby when the bottom of said seat comes to rest on said seat support surface, said sound deadening material minimizes noise.
