Abstract: A sealing strip for sealing between a flange defining the door opening, such as in a motor vehicle body, and the door of the opening, comprises a channel-shaped gripping part for gripping the flange and supporting a hollow tubular sealing part, preferably made of sponge rubber. The latter is partially compressed between the flange and the closing door so as to provide a barrier against ingress of moisture and draft. In order to provide improved blocking of acoustic energy, so as to reduce the amount of exterior noise (road noise, aerodynamic noise) transmitted into the interior of the the vehicle, the hollow tubular sealing part supports a metal wire running lengthwise along and within the hollow tube and supported from the tubular side wall so as to be capable of vibrating in a transverse direction.

Abstract: An antivibration elastic support, particularly for the power plants of autovehicles. It essentially consists of an elastomer hollow unit (1), made to adhere to two rigid reinforcements (2)-(3) during vulcanization, the lower reinforcement (3) exhibiting an opening that can be stopped by an additional rigid reinforcement (4), the fluid-tight chamber (5), consisting of the walls of the hollow elastomer unit (1) and the reinforcements (2)-(4), being at least partially filled with a material that is easily deformable by outside application of energy, with absorption of the latter.
