Back support for a seat
First Claim
Patent Images
1. A seat, comprising:
- a base assembly;
a seat assembly interconnected to said base assembly;
a frame assembly extending upwardly from one of said base assembly and said seat assembly and providing a substantially rigid structurea back support having a first end coupled to a first end of said frame assembly, and a second end coupled to a second end of said frame assembly, said back support including a plurality of back support members intermediate said first and second ends of said frame assembly, each of said plurality of back support members having a longitudinal surface engaging a longitudinal surface of an adjacent back support member;
a clamping assembly extending through each of said back support members and interconnecting said first and said second end of said frame assembly for placing said plurality of back support members in and out of compression relative to one another and fixing a relative position of each back support member relative to an adjacent back support member; and
at least one biasing member disposed within said back support for providing a resistive and restoring force to said plurality of back support members.

Abstract
An self adjusting back support assembly for a seat is provided comprising a plurality of pivotally adjustable back support members juxtaposed one another such that each of said back support members is able to pivot about an axis contained wholly within an adjacent back support member allowing the back support assembly to adopt a serpentine contour substantially following a contour of an occupant'"'"'s back.

25. A back assembly for a seat, comprising:
-
a substantially rigid frame assembly adapted to be connected to one of a seat assembly and a base assembly of the seat, said frame assembly having an upper end and a lower end; a back support assembly having a length greater than said frame assembly, said back support assembly disposed between said upper end and said lower end of said frame assembly, said back support assembly comprising a plurality of back members juxtaposed serially to one another and in contact with adjacent ones of said back members a tensioning assembly extending through each of said back members for selectively placing said plurality of back members in and out of compression relative to one another; and at least one biasing member extending through each of said back members for providing a resistive and restoring force to said back support assembly. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

36. A back support assembly for a seat, comprising:
- a substantially rigid frame assembly adapted to be connected to one of a seat assembly and a base assembly of the seat, said frame assembly having an upper end and a lower end;
a back support assembly having a length greater than said frame assembly, said back support assembly disposed between said upper end and said lower end of said frame assembly, said back support assembly including a plurality of back members juxtaposed serially to one another and in contact with adjacent ones of said back members, each including at least one of a convex and a concave surface;
each of said plurality of back members having one of said convex and said concave surface that moves along one of said convex and concave surface of a juxtaposed back member;
a tensioning assembly extending through each of said back members for selectively placing said plurality of back members in and out of compression relative to one another; and
at least one biasing member extending through each of said back members for providing a resistive and restoring force to said back support assembly.

37. A self adjusting back support assembly for a seat, comprising:
- a rigid frame member adapted to be connected to one of a seat assembly or a base assembly of the seat and having a first end and a second end;
a back support assembly having a length greater than said frame assembly, said back support assembly disposed between said first end and said second end of said frame member, said back support assembly including a plurality of pivotally adjustable back members juxtaposed serially to one another and in contact with adjacent ones of said pivotally adjustable back members, intermediate said first end and said second end of said rigid frame member, each of said back members including one of a convex and a concave surface in sliding engagement with one of a convex and a concave surface of a juxtaposed back member, allowing the back support assembly to adopt a serpentine contour substantially following a contour of an occupant'"'"'s back;
a tensioning assembly extending through each of said pivotally adjustable back members for selectively placing said plurality of pivotally adjustable back members in and out of compression relative to one another; and
at least one biasing member extending through each of said pivotally adjustable back members for providing a resistive and restoring force to the back support assembly.
