20080277985 | Lumbar Support - The invention relates to a lumbar support comprising a plurality of pneumatically operated chambers ( | 11-13-2008 |
20080296946 | Seat System With Shock- And Vibration-Reducing Bladders - A seat system has separate air bladders in the seat bottom and seat back. The seat bottom bladder is in fluid communication with the seat back bladder through a plurality of rigid interconnecting tubes, and valves in the tubes or orifice size can control flow rate of air exchange between the seat bottom bladder and the seat back bladder. A panel of resilient, compressible open cell foam extends in each of the seat bottom bladder and the seat back bladder. Through-holes in the foam panel permit accelerated air evacuation to the other bladder when the seat withstands a significant shock event. The vibration and shock attenuation characteristics of the seat are jointly provided by the panel spring force and the bladder air pressure. | 12-04-2008 |
20090273218 | Pumping device for seat cushion of vehicle - The present invention relates to a pumping device for a seat cushion of a vehicle, in which a brake assembly | 11-05-2009 |
20100026067 | Machine and pneumatic seat assembly having air container with integral air compressor housing - A machine includes a machine body having an operator station and a seat assembly position at the operator station. The seat assembly includes a pneumatic support element that includes an air container having an air compressor positioned therein. The air container includes a deformable section, and a rigid section that includes a housing for the air compressor. Forming the air compressor housing integrally with the air container minimizes leak paths and improves packaging. | 02-04-2010 |
20130062920 | CHAIR WITH INFLATABLE BLADDER SYSTEM - An improved office chair, having an inflatable seat bladder and seat-support coils, and an inflatable lumbar back bladder wherein each bladder is independently inflatable and independently deflatable to the user's desired firmness, through a dedicated inflation mechanism for each bladder, comprising a battery-powered air pump and a check valve, and a dedicated deflation mechanism for each bladder, comprising a battery-powered solenoid valve, wherein each inflation mechanism and deflation mechanism is battery-powered through an onboard battery pack and controlled by the user's manipulation of switches in an onboard control panel. | 03-14-2013 |
20140232155 | SEAT ADJUSTING DEVICE AND METHOD OF PROVIDING SEAT ADJUSTMENT - A seat adjusting device comprises a plurality of inflatable chambers and a valve module. The plurality of inflatable chambers includes a first inflatable chamber and a second inflatable chamber. The valve module comprises a control valve which is a 4/4-way valve having four ports and four positions. A first port of the control valve is in communication with the first inflatable chamber and a second port of the control valve is in communication with the second inflatable chamber. | 08-21-2014 |
20150115678 | MANUAL LUMBAR PUMP ASSEMBLY - A pump assembly for a vehicle seatback includes a plurality of air bladders defining a lumbar support. A valve body has an inlet and a plurality of outlets that are coupled with the associated plurality of air bladders. A selection device is operably coupled with the valve body for engaging a select one of the plurality of air bladders with the inlet. A manually compressible air chamber is coupled with the inlet for inflating the select one. | 04-30-2015 |
20160046207 | ADJUSTABLE FIRMNESS VEHICLE SEAT - A vehicle seat is provided herein. The vehicle seat includes a cushion disposed within a seating member having at least one inflatable first bladder for selectively adjusting the firmness of the cushion. An inflatable second bladder is separated from a support surface of the seating member by the first bladder and fluidly connected to the first bladder. A vehicle seat hip pivot point is maintained when adjusting the firmness of the cushion by increasing the pressure in the second bladder when the pressure in the first bladder is selectively decreased, and by decreasing the pressure in the second bladder when the pressure in the first bladder is selectively increased. | 02-18-2016 |
