Seat subportion adjustable in relative height and/or angle and backrest adjustable in shape based on user contact pressure

Abstract

A seat of an apparatus in one example comprises a front subportion and a rear subportion that is adjustable in height and/or angle relative to the front subportion. A backrest of the apparatus in one example is adjustable in shape. Based on a user contact pressure against one or more portions of the seat and/or one or more portions of the backrest, the rear subportion of the seat and the backrest are adjustable between: a first height and/or angle of the rear subportion of the seat and a first shape of the backrest; and a second height and/or angle of the rear subportion of the seat and a second shape of the backrest.

       20 . An article, comprising:
 one or more computer-readable signal-bearing media;   means in the one or more media for a controller coupled with an apparatus to actively adjust a backrest between a first shape and a second shape based on a user contact pressure against one or more portions of the backrest and/or one or more portions of a seat; and   means in the one or more media for the controller to actively adjust a rear subportion of the seat between a first height and/or angle and a second height and/or angle relative to a front subportion of the seat based on the user contact pressure against the one or more portions of the backrest and/or the one or more portions of the seat.   
   
   
       21 . The computer-readable signal-bearing media of  claim 20  wherein the signal-bearing media is an electronic storage device selected from the group consisting of magnetic, electrical, optical, biological, and atomic data storage mediums. 
   
   
       22 . The computer-readable signal-bearing media of  claim 21  wherein the signal-bearing media is a read-only device. 
   
   
       23 . The computer-readable signal-bearing media of  claim 21  wherein the signal-bearing media is a device capable of read and write operations. 
   
   
       24 . The computer-readable signal-bearing media of  claim 20  wherein the signal-bearing media is a modulated carrier signal transmitted over a network. 
   
   
       25 . The computer-readable signal-bearing media of  claim 24  wherein the signal-bearing media is a wireless connection. 
   
   
       26 . The computer-readable signal-bearing media of  claim 24  wherein the signal-bearing media is a wire-line connection.
