Patent number: 7469733Abstract: A tyre for a vehicle wheel comprising two sidewalls, a tread, beads, the sidewall intended to be positioned on the interior side of the vehicle being shorter than that intended to be positioned on the exterior side of the vehicle, a reinforcement structure extending between the beads and maintained in said beads by anchoring zones, each of the beads comprising a specific and distinct arrangement of the anchoring zone thereof, such that the anchoring zone of the bead intended to be positioned on the exterior side of the vehicle exhibits a greater anchoring capacity than the anchoring zone of the bead intended to be on the interior side of the vehicle. The internal and external anchoring zones are thus arranged in such a manner as to produce, in operation, a rim clamping load which is substantially identical on each side.Type: GrantFiled: March 16, 2006Date of Patent: December 30, 2008Assignee: Michelin Recherche Et Technique S.A.Inventors: Bernard Guerinon, James Robert Anderson, David Jardine, Jean-Jacques Drieux

Patent number: 7296605Abstract: Vehicle tire including two sidewalls, beads which include a seat and an external flange which are intended to come into contact with a suitable rim, and a carcass reinforcement structure. At least one bead comprises a circumferential cord structure distributed in two regions, and an anchoring region in which the reinforcement structure is anchored in the bead, that region including circumferential cords arranged as stacks distributed symmetrically on opposite sides of the reinforcement structure. The center of inertia of the bead is located in the immediate vicinity of the anchoring region.Type: GrantFiled: April 14, 2005Date of Patent: November 20, 2007Assignee: Michelin Recherche et Technique S.A.Inventors: Bernard Guerinon, David Jardine, James Robert Anderson, Jean-Jacques Drieux

Patent number: 7172009Abstract: A device designed for demounting a tire from a rim at least one of whose seats is inclined outwards, the device being in the form of an insert (4) of length (L) with three faces and whose cross-section in a transverse plane is triangular overall with a contour formed by two long sides (41, 42) and a short side (43), the angle between the long sides being close to the angle between the rim seats and the rotation axis, the length of the short side being essentially equal to the height of the projection of the outward-inclined rim seat, this insert (4) comprising on its face intended to come in contact with a bead seat at least one relief (421, 422) designed to interact with said bead seat (11) so as to keep the insert engaged with the bead.Type: GrantFiled: June 28, 2005Date of Patent: February 6, 2007Assignee: Michelin Recherche et Technique S.A.Inventors: René Balichard, Romuald Gaillardon, Jean-Jacques Drieux, David Jardine

Patent number: 7051779Abstract: A tire comprising two sidewalls, beads, a reinforcement structure extending radially from each of the beads towards the crown zone, at least one of said beads comprising: a bead seat of inverted type; an anchoring zone for the reinforcement structure in said bead, comprising an arrangement of circumferential cords, a bonding mix being arranged between the circumferential cords and the reinforcement structure, said bonding mix of the anchoring zone having a elasticity modulus at a deformation of 10% of less than 20 MPa and preferably between 10 and 20 MPa; an axially outer zone arranged in the zone of the bead; a bearing zone for said bead. The anchoring rubber mix makes it possible, in spite of its rigidity which is very much less than what was advocated previously, to retain very satisfactory endurance properties.Type: GrantFiled: May 18, 2005Date of Patent: May 30, 2006Assignee: Michelin Recherche et Technique S.A.Inventors: Bernard Guerinon, Jean-Jacques Drieux, James Robert Anderson, David Jardine

Patent number: 6766840Abstract: The invention concerns a tire whose crown contains a ply of circumferentially oriented cords. That ply is so arranged that in sensitive zones, as, for example, at the side ends of the adjacent crown reinforcing ply, the laying pitch of the circumferentially oriented cords is markedly increased. That considerably lessens the risk of damage to the circumferentially oriented cords in those zones.Type: GrantFiled: May 3, 2002Date of Patent: July 27, 2004Assignee: Michelin Recherche et Technique S.A.Inventors: Pedro Costa Pereira, David Jardine
