Abstract

A safety molding for electrically actuated sliding windows, such as in motor vehicles, consists of an elastomeric material formed in a U-shaped configuration providing a groove into which the sliding window seats in its closed position. One of the legs of the U-shaped molding contains a longitudinally extending cavity in its interior and a flexible electrical conductor is fitted in a channel formed in the wall of the cavity adjacent the free end of the leg. A metal rib is positioned within the cavity in normally spaced relationship from the conductor. When a pressure is exerted against the outer surface of the free end of the leg containing the cavity, the flexible conductor deflects into contact with the metal rib so that a drive motor for the electrically actuated window can be stopped to avoid any injury or damage if someone or something is located in the path of the closing window and prevents it from moving into its closed position.

Claims

1. A safety molding for use with electrically actuated sliding windows, such as vertically or approximately vertically movable motor vehicle windows, comprising a longitudinally extending molding formed of an elastomeric material and arranged to be secured to the edge of a window frame opening in which the window seats in its closed position, said molding having a first surface facing in the direction from which the window moves into its closed position, said molding having a U-shaped configuration comprising a pair of laterally spaced legs joined together by a cross-member defining a groove formed in the first surface of said molding and into which the window seats in its closed position, one of said legs having a bead-like configuration at its end spaced from said cross-member and the bead-like configuration forming a portion of the first surface of said molding and projecting away from said cross-member a greater distance than the corresponding end of the other one of said legs, a cavity located within the one of said legs having the bead like configuration and extending therethrough in the longitudinal direction of said molding and said cavity located adjacent said first surface, a longitudinally extending channel formed in the portion of the wall of said cavity which is adjacent to the first surface at the end of the one of said legs spaced from said cross-member, a conductor positioned within and extending through said channel, a longitudinally extending metal rib extending through said molding from the surface thereof opposite said first surface into said cavity and having a longitudinally extending end located within said cavity and disposed in spaced juxtaposed relationship to said conductor, the surface of said conductor facing toward the juxtaposed end of said rib is exposed and said rib is grounded so that when local pressure is exerted against the first surface on the end of said one of said legs spaced from said cross-member said conductor is deflected into contact with said rib and effects a circuitclosing contact for discontinuing the closing movement of the window, said one of said legs having a slot-like opening extending therethrough from said cross-member into said cavity, said metal rib is positioned within said slot-like opening extending therethrough into said cavity from the exterior of said molding on the opposite side thereof from said first surface, said metal rib has a U-shape configuration with its bight portion located within said cavity and its legs extending outwardly therefrom through said slot-like opening, the opening defined by the U-shape configuration of said metal rib being arranged to engage an edge of the window frame opening, and the leg of said metal rib spaced more remotely from the groove formed in said molding being bent over into overlapping contact with the outer surface of said leg through which it extends.

2. A safety molding, as set forth in claim 1, wherein the walls defining the sides of said cavity between the wall containing said channel and the wall through which said metal rib extends are reduced in thickness as compared to the adjacent portions of said leg containing said cavity for increasing the deformability of the free end surface of said leg.

3. A safety molding, as set forth in claim 1, wherein a pile layer is positioned on the oppositely facing surfaces within the channel in said molding into which the window seats in its closed position.

4. A safety molding, as set forth in claim 1, wherein said channel in said cavity is undercut for securing said conductor therein.
