Patent ID: 7322651

Claim:
An apparatus, comprising: a seat that comprises a front subportion and a rear subportion that is adjustable in height and/or angle relative to the front subportion; a backrest that is adjustable in shape; and a controller communicatively coupled with the seat, the backrest, and one or more input components that comprise one or more contact pressure sensors and one or more air pressure sensors; wherein one or more of the one or more contact pressure sensors measure a user contact pressure against one or more portions of the seat and/or one or more portions of the backrest; wherein one or more of the one or more air pressure sensor measures an air pressure within one or more air bladders under the rear subportion of the seat and an air pressure within one or more air bladders embedded in a lumbar region of the one or more portions of the backrest; wherein, based on the user contact pressure against one or more portions of the seat and/or one or more portions of the backrest, the air pressure within the one or more air bladders under the rear subportion of the seat, and the air pressure within the one or more air bladders embedded in the lumbar region of the one or more portions of the backrest as feedback signals to the controller, the rear subportion of the seat and the backrest are actively adjustable based on a command from the controller 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.
