Abstract:
A tire configured to be mounted on a mounting rim, comprising two beads, a crown comprising a tread, two sidewalls, a carcass reinforcing armature, and a membrane situated radially on the inside of the carcass reinforcing structure, this membrane comprising: (a) a membrane reinforcing armature anchored in each bead to the annular reinforcing structure, said membrane comprises a layer of reinforcement elements directed substantially radially and (b) an airtight layer of rubber mix; wherein the membrane is arranged in such a way that part of the membrane together with part of the carcass reinforcing armature delimits a chamber extending transversely and circumferentially; wherein, in any radial section, the curved length Lm of the trace of the surface of the chamber delimited by the membrane is greater than the curved length Lc of the trace of the surface chamber delimited by the carcass reinforcing armature (Lm>Lc).
Abstract:
An airbag device for a vehicle tire capable of stabilizing the vehicle timely when the tire is exploding or being punctured suddenly to avoid potential accidents and to ensure driving comfort. The airbag device comprises a resilient outer ring installed between the tire and the wheel hub, and an inner ring serving to support the resilient outer ring. The resilient outer ring and the inner ring are compressed between the tire and the wheel hub under normal tire air pressure, and a space serving to increase driving comfortability and keep the outer ring from contacting the inner surface of the tire tread is designed between the resilient outer ring and the inner surface of the tire tread. When the tire is exploding or the air pressure of the tire is lost, the resilient outer ring is capable of bouncing instantly to support the weight of the vehicle.
Abstract:
It is to solve a problem of an elongation of a partition in a safety tire wherein hollow particles called as a foamable composition are filled in a hollow ring-shaped partition and to propose a safety tire with a partition structure sufficiently developing a function of hollow particles. In a safety tire comprising a tire-approved rim assembly formed by assembling a tire onto an approved rim, a chamber defined inside the assembly through a hollow ring-shaped partition and extending along the rim in a circumferential direction, and thermally expandable hollow particles filled in the chamber, each of which particles consisting of a continuous phase of a resin and a closed cell(s), a hollow ring-shaped sub-partition is disposed on at least radially outside of an outer peripheral portion of the partition and a tire internal pressure is applied to an inside of the sub-partition.
Abstract:
A tire configured to be mounted on a mounting rim, comprising two beads, each bead comprising an annular reinforcing structure and a seat configured to come into contact with the mounting rim; a crown comprising a tread; two sidewalls, each sidewall extending between a bead and the crown; a carcass reinforcing armature extending from one bead to the other and anchored within each bead to the annular reinforcing structure; and a membrane situated radially on the inside of the carcass reinforcing armature, this membrane comprising: (a) a membrane reinforcing armature anchored in each bead to the annular reinforcing structure, wherein the membrane reinforcing armature comprises a layer of reinforcement elements directed substantially radially, that is to say which make an angle greater than or equal to 65° and less than or equal to 90° with respect to the circumferential direction; and (b) an airtight layer of rubber mix; wherein the membrane is arranged in such a way that part of the membrane together with part of the carcass reinforcing armature delimits a chamber extending transversely and circumferentially, this chamber being situated radially on the inside of the carcass reinforcing armature and, to a large extent, under the crown, the chamber being filled with at least one fluid; wherein, in any radial section, the curved length Lm of the trace of the surface of the chamber delimited by the membrane is greater than the curved length Lc of the trace of the surface of the chamber delimited by the carcass reinforcing armature (Lm>Lc).
Abstract:
A body (30) designed to be placed inside a tire (10) so as to seal any puncture which a sidewall (12) of said tire may suffer while providing said tire with support. The body (30) comprises a flexible skin (31), of resilient elastomeric material, reinforced by a carcass reinforcement (311) anchored to two inextensible circumferential reinforcement structures (33) incorporated in said skin. The carcass reinforcement (311) is capable of withstanding the forces applied by an inflation pressure corresponding to the rated inflation pressure of the tire inside which the body (30) is placed. An assembly is disclosed formed of a tire (10) mounted on a rim (20) and equipped with such a body (30).
Abstract:
A tire pressure monitoring and reporting instrument is mounted within a valve stem and has a valve cap. A single circuit can be provided having an LED, a sounder, a battery and a switch. A dual stage system, or a continuously variable system can be implemented by using a dual stage pressure switch or a continuously variable pressure switch. The battery may be housed within the cap and electrical contacts between the cap and stem allow discontinuation of the circuit or changing of the battery.
Abstract:
A tire capable of stably running even if the tire is subjected to external injury without sacrificing rolling resistance and ride comfort in the usual running before being subjected to external injury, is provided. A composite body consists of a continuous phase of a resin and closed cells arranged in an inside of a hollow doughnut-shaped tire and the composite body has a cell content of 80.00 vol % to 98.75 vol %, and an internal pressure at 25° C. in the closed cell included therein is not less than 150 kPa as an absolute pressure.

Abstract:
Toric membrane M used as a support means for the tread of a tire P and forming together with the said tire P and its mounting rim J an assembly that can roll when the tire P suffers a loss of pressure, the said membrane M being expandable, capable of filling the internal cavity of the tire P, consisting of an airtight interior layer (10), a crown reinforcement (14) comprising two crossed plies (141, 142), two carcass half-plies (111, 112) anchored in each bead B reinforced by a reinforcement ring (2) and a cap (17) reinforced by a hopping armature (16), the crown reinforcement (14) being detached from the interior layer (10) and from the edges of the carcass half-plies (111, 112) which are on either side of the equatorial plane XX′ and are connected by at least one connecting ply (15).
Abstract:
A safety liner (20) for a vehicle tire (500) includes a toroidal tube (22) having at least one hole (24). At least one plug (26) is selectively insertable into the at least one hole (24). Toroidal tube (22) is compressible into a flattened circular shape by a compressive force, and when the compressive force is removed, the toroidal tube (22) resiliently assumes its original toroidal shape. Safety liner (20) is installed in the cavity (503) of vehicle tire (500) as the vehicle tire (500) is being installed on the tire rim (502). If a blowout or other leak occurs, safety liner (20) will cause the shape and pressure of vehicle tire (500) to be retained for a period of time.
