Patent ID: 6948719

Claim:
An extruded sealing section with a U- or Ω-shaped transversal section, made of elastomer or plastomer, without a rigid reinforcement buried partially in its mass, and being designed to be mounted on a projecting part of a structure, especially a frame for an opening in the body of a car, by means of a tight clamp, comprising: two elastomer or plastomer jaws, each comprising a wing and an adjacent part forming a portion of the section base, said two jaws preferably being arranged in more or less symmetrical fashion along a cross-section of the section and separated from each other by an opening made through the section base and extending lengthwise along its median part; a layer of a flexible material that is inextensible or slightly extensible, applied to the interior of the two jaws so as to secure the two wings and the adjacent parts to their respective section base; a wedging shim with a cross-section substantially similar to that of the opening separating the jaws, into which it is engaged by force, the cross-section of the opening being such that when the wedge is fixed in place, it causes these jaws to swing away from each other thanks to the layer of flexible material connecting the two jaws, thereby bringing the free ends of the section's two wings closer together; and a sheet or a fabric made of an inextensible material buried in the layer of material that is inextensible or slightly extensible.
