ABSTRACT:
A hydraulic antivibration support has a strength member connected to a plate by an elastomer body whose base is pressed against the plate to define two hydraulic chambers and a narrow channel, all filled with liquid. The base of the elastomer body has two opposite sides that are crimped onto the plate and two free sides that are not crimped, each of the free sides having a projecting peripheral sealing lip which is compressed against the plate and which is of asymmetrical profile that is not perpendicular to the support face of the plate, being inclined throughout in the same direction relative to the support face.
