  • Patent number: 12331834
    Abstract: A seal includes an undulating profile following a circumferential path centered on a main axis, such that the path has a variable axial amplitude relative to a reference transverse plane perpendicular to the main axis between two, lower and upper, transverse planes and defines a non-planar geometric profile of the seal. The undulating profile has at least two peaks and at least two troughs that are formed by axial excursions relative to the transverse reference plane so that compression of the seal follows a stepped profile in which the steps are defined by the upper and lower planes and intermediate planes located between the upper and lower planes.

  • Patent number: 11953130
    Abstract: A cylindrical cavity for receiving the tubular article and a metal casing body delimiting a seat substantially inside which the insert is wrapped around the article, the insert having an external projection which extends radially towards the exterior of the insert and is configured to cooperate with a corresponding orifice formed in the seat of the metal body so as to position the insert inside the body, the projection comprising a base attached to the insert and a head provided at the periphery of the head with a protruding clipping edge configured to hold the insert inside the metal casing body. The insert has, at the base of the projection, a through hole extending in line with the clipping edge.

  • Publication number: 20200240550
    Abstract: A hinged clamping bracket for at least one tubular article. The bracket for at least one tubular article includes lower and upper separable members which are complementarily shaped to define at least one cylindrical clamping housing for receiving the tubular article and a hinge pivotally connecting the members for relative rotating movement. More specifically, the lower and upper members include respectively lower and upper articulating portions each provided with a seat defining a substantially semi-cylindrical receiving space and forming respectively lower and upper articulating parts of the hinge, thereby forming a rotatable pivot assembly with the tubular article in the clamping bracket assembling position in which the two separable members are rotationally articulated about the tubular article acting as the pivot axis of the hinge.

  • Patent number: 10710528
    Abstract: A bracket intended to be fastened to a support, such as a chassis or an engine of a vehicle, preferably a motor vehicle, the bracket having at least a body including: a first end configured to be fastened to a support, a second end opposite to the first end, an intermediate portion arranged between the first end and the second end, the second end being bent so as to form a recess oriented toward the first end and facing the intermediate portion, wherein the bracket further includes an elastic insert arranged in the recess of the second end.

  • Patent number: 10364919
    Abstract: Invention relates to a manufacturing process for making a bracket and subset assembly, process including: step (a) of placing bracket within a forming tool and putting between first portion of said bracket and second portion of said bracket a subset having a tube element and an elastic pad, step (b) of actuating the forming tool for plastically deforming the bracket so the first and second portions of the bracket come closer one to the other and press subset, thus gripping subset between the first and second portions of bracket, and during the step of actuating the forming tool for plastically deforming bracket, step (c) of using a propping spacer, distinct from the subset, for stopping the second portion of the bracket at a predetermined clamping distance from the first portion of the bracket, to secure the subset without crushing it.
