| 152518000 | Utilizing additional inflatable supports which become load bearing in emergency | 11 |
| 20090260734 | SAFETY WHEEL FOR VEHICLE - A safety wheel for a vehicle includes a rim having a body and a protrusion extending outward from an outer circumference of the body, and having a fastening groove; a first rubber layer wrapped on the protrusion of the rim; an air-filled tube disposed on the first rubber layer, and having a hollow body filled with compressed air therein; an outermost second rubber layer wrapped on the rim protrusion, the first rubber layer and the air-filled tube; and a rubber sheath wrapped on the rim protrusion, the first rubber layer, the air-filled tube and the second rubber layer. The safety wheel maintains pressure to support the weight of the vehicle, and even if the tire is blown out, prevents the vehicle from rocking and overturning due to inclination, as well as affords stability so that the vehicle can travel for a predetermined distance. | 10-22-2009 |
| 20100096059 | RUNFLAT DEVICE AND A METHOD FOR FITTING THE SAME - The present invention relates to a runflat device arranged to be disposed within a wheel well of a wheel having a rim ( | 04-22-2010 |
| 20100212800 | Dual Structure Tire Wheel and Method for Installing it - It is an object of the present invention to provide a useful inner structural supporter type run flat tire having enough structural strength for controlling the steering wheel to some extent when the tire goes flat and having easy structure for installing to the rim wheel. A wheel | 08-26-2010 |
| 20190143763 | Insert for a Pneumatic Tire | 05-16-2019 |
| 152519000 | Inflated or expanded in emergency only | 7 |
| 20080257470 | Unpuncturable Inner Tube - The invention relates to a device for inserting inside tires of a vehicle so that it follows its course without stopping after a bursting. The device comprises a cluster of flexible bladders ( | 10-23-2008 |
| 20110030867 | PNEUMATIC TIRE SECURITY SYSTEM - A system for allowing vehicles equipped with pneumatic tires to continue operating after a tire failure which would normally cause deflation of the tire employs one or more airbags stored in deflated configuration either about the exterior surface of the rim supporting the pneumatic tire or externally of the tire. The system further includes a container for compressed gases. A sensor connected to the inflated tire to detect sudden deflation releases the compressed gases so as to inflate the airbag to either support the tire or provide an exterior running surface adjacent to the deflated tire. | 02-10-2011 |
| 20110030868 | PNEUMATIC TIRE/RIM ASSEMBLY - Provided is a pneumatic tire/rim assembly which is improved in the run-flat durability with the mass of the tire being reduced. In a pneumatic tire/rim assembly with a run-flat capability, an air bladder ( | 02-10-2011 |
| 20110073231 | SAFETY TIRE - Present invention provides a safety tire which could increase the running distance in the run-flat state by adequately configuring a diaphragm. The safety tire has an inflatable annular or hollow toroidal diaphragm which fractionates a tire cavity to an outer chamber and an inner chamber, the diaphragm having a communicating part communicating the outer chamber with the inner chamber, when the tire and the diaphragm is attached onto a rim and the inner and outer chamber is filled with a first internal-pressure, and the communication part being closed when the internal-pressure of the outer chamber drops from the first internal-pressure beyond a second internal-pressure. | 03-31-2011 |
| 20130020004 | PNEUMATIC TIRE SECURITY SYSTEM - A system for allowing vehicles equipped with pneumatic tires to continue operating after a tire failure which would normally cause deflation of the tire employs one or more airbags stored in deflated configuration either about the exterior surface of the rim supporting the pneumatic tire or externally of the tire. The system further includes a container for compressed gases. A sensor connected to the inflated tire to detect sudden deflation releases the compressed gases so as to inflate the airbag to either support the tire or provide an exterior running surface adjacent to the deflated tire. The system may employ a rim with a specially deep drop-center section to allow mounting and dismounting a tire in a conventional manner despite the space in the drop-center section occupied by airbags. | 01-24-2013 |
| 20150013870 | PNEUMATIC TIRE SECURITY SYSTEM EMPLOYING INTERNAL HIGH PRESSURE AIR BAG - A system for allowing a pneumatic tire supported on a wheel rim of a vehicle to continue in operation after rupture of the tire. The system includes an air bag container which divides the interior tire volume into a radial outer chamber providing normal pressure for inflation of the tire and a radial interior chamber, within the air bag, which is inflated to a substantially higher pressure. The container is intended to rupture when the tire is deflated by a puncture or the like allowing the higher pressure air bag to escape from its container and fill the entire tire volume at a normal operating pressure. | 01-15-2015 |
| 20160075191 | EXPLOSION-PROOF TIRE - The present invention relates to an explosion-proof tire, comprising a safety airbag, trigger sensors and a safety switch, wherein the safety airbag is arranged between a tire and a hub; the hub is provided with grooves; trigger devices of the safety airbag are arranged in the grooves; one end of each trigger sensor sticks into the tire; and the other end thereof is connected with a trigger device. The safety switch is arranged on the valve stem of the tire; and positive and negative electrodes on the valve stem are each connected with a trigger device. | 03-17-2016 |
