A tire is described that includes a casing defining a cavity and equipped to receive an object, such as an electronic circuit, for example, through use of a two-part attachment, such as a touch-close attachment, of which a first part is fixed to a wall of the casing and a second part can be joined to the first part when placed in contact with the first part to keep the object on the casing in a service position. The first part of the attachment includes connection elements that are an integral part of the wall of the casing of the tire. The connection elements allow these two parts to have freedom to move relative to each other, thereby limiting the transmission of stresses, which affect the wall of the tire, to the object. The connection elements may be loops of flexible thread formed by the extremities of turns of a coiled thread integrated into the wall of the tire during the tire's manufacture.

Tyre equipped for attaching an object to the wall thereof and method for making same

A member for attachment to tire includes a functional object in suspension in a soft substance of very high deformability.

Tyre equipped for attaching an object to a wall thereof

A tire is described that includes a casing designed to be inflated to a service pressure and equipped to accept a functional object, such as an electronic circuit, for example, by means of a two-part fastener, such as a touch-close fastener, for example. A first part of the fastener is attached to a wall of the casing, while the second part can be joined to the first part when placed in contact with the first part to attach and keep the object on the casing when the tire is in service. The first part of the fastener includes a thin backing fixed to the wall of the casing and possessing a structural elongation capacity greater than or equal to that of the wall to which the thin backing is fixed. The presence of the thin backing does not significantly hinder the elongation of the wall of the casing when subjected to the stresses encountered during use of the tire and, where relevant, during its manufacture. Connection elements between the first and second parts give these parts a certain looseness with respect to each other so that the object held by the second part of the fastener is not subjected to all or some of the stresses occurring in the wall during operation.

Tyre equipped for attaching an object to the wall thereof and fastener therefor

A tire includes a cavity formed therein to receive a removable electronic monitoring module. A mouth of the cavity opens into the inside volume of the tire and is located along a section of a joint of a first layer formed by the assembly of rubber profiled elements adjacent to the inside volume of the tire. The joint can extend radially or circumferentially. The cavity can be formed by inserting an element into the tire body and then leaving the element in place or removing it prior to vulcanization.
