20140319890 | SEATING WITH ADJUSTABLE CUSHIONS - A seating, including a sling seating, can have adjustable and/or non-adjustable cushions. An occupant of the seating can adjust the thickness and support provided by an adjustable cushion. The adjustable cushion can include an open cell foam in an airtight envelope. The occupant can open a control valve connected to the envelope to let air out of the airtight envelope while the occupant applies external pressure to the open cell foam, which decreases the thickness of the adjustable cushion as the open cell foam compresses. The occupant can close the valve to restrict airflow into and out of the envelope at a desired thickness of the adjustable cushion. The occupant can subsequently open the valve to let air into the envelope while the occupant does not apply external pressure to the open cell foam, which increases the thickness of the adjustable cushion as the open cell foam expands. | 10-30-2014 |
20150008712 | ANATOMIC DESK CHAIR COMPRISING BACKREST WITH FRAME HAVING A TIRE-TYPE ASSEMBLY SYSTEM - The present invention relates to an anatomic desk chair for office or home work, which has a displacement system composed by a plurality of wheels which allow the user to move from one location to another, wherein the chair is characterized by comprising a backrest having a frame with a tire-type assembly system, i.e. wherein the backrest as such is made of an elastomeric material and is assembled in the frame by pressure and these are adjusted through a series of screws attaching the frame and the counter-frame. Thus, the assembly system is composed by a back support or “skeleton” which corresponds to a piece injected in an elastomer requiring of a stretching process subsequent to the injection in order to obtain the shape and dimension sufficient to assembly in the frame with a tire-type system, after such skeleton-frame assembly the counter-frame is assembled through screws as previously indicated. | 01-08-2015 |
