A dock seal (20), such as a head seal (22) mountable above a doorway (14) of a loading dock (12), includes a compressible body (36) with a support panel (44). The compressible body can conformably seal against the rear edge (26) of a vehicle's (10) enclosed trailer as the vehicle backs the trailer up against the seal (20). The support panel (44) provides relatively dense structure for mounting the seal to the wall (16) of a building. Compared to the horizontal distance that the compressible body (36) projects from the wall, the support panel (44) is ultra- thin to avoid consuming compressible space between the wall and the rear of the trailer. In some cases, a flexible panel (56) suspends the compressible body and its support panel (44) from the wall (16) such that the flexible panel (56) allows the dock seal (20) to move relative to the wall.
L'invention concerne un sas d'étanchéité tel qu'un joint supérieur pouvant être monté au-dessus d'une baie de porte d'un quai de chargement, qui comprend un corps compressible comportant un panneau support. Le corps compressible peut former un joint hermétique en épousant le bord arrière d'une remorque fermée d'un véhicule lorsque le véhicule fait appuyer la remorque contre ledit corps. Le panneau support forme une structure relativement dense qui permet de monter le joint sur la paroi d'un bâtiment. En comparaison de la distance de saillie horizontale du corps compressible par rapport au mur, le panneau support est ultramince afin d'éviter de réduire l'espace compressible entre la paroi et l'arrière de la remorque. Dans certains cas, un panneau flexible permet de suspendre au mur le corps compressible et le panneau support associé, de sorte que le panneau flexible permet au sas d'étanchéité de se déplacer par rapport à la paroi.
