    Abstract: A seal for a fixed window in a motor vehicle, including a pane-holding channel to receive and grip the opposite faces of a margin of a window pane. A sealing lip extending parallel with the pane-holding channel has a root located a small distance apart from the top edge of the pane-holding channel, and an outer margin of the lip extends to and presses sealingly against an outer surface of the window pane. In a preferred embodiment of the invention an outer margin of the main member of the seal defines a channel to receive and grip the opposite faces of a margin of the structure defining a window opening in the motor vehicle. A locking strip engaged in a locking strip groove keeps the seal in place after installation. Where two seal members meet, the respective sealing lips meet to form a curved concave corner.

    Abstract: A mounting arrangement for a moving vehicle window that is designed for a limited reduction in the window's sight. The mounting arrangement consists of a holding element attached to the edge of a car window pane via an adhesive. The holding element is formed when a curable compound is poured into two mold halves. Attached to the holding element is a functional element. In one embodiment of the invention, the functional element is a seal, designed to seal a gap between the window pane and a car door. In another embodiment of the invention, the functional element is designed as an electric pressure detector to shut the electric closure motor off when the functional element becomes compressed.

  • Patent number: 6039907
    Abstract: To postform the region of transition between the initial part and the end part of a section piece forming a closed frame and applied to window glass (1) by extrusion, use is made of a mould (14) which pivots about an axis parallel to the longitudinal axis of the extruded section piece and which is situated in the region of the surface of the window glass (1). The axis of pivoting of the mould (14) coincides with the cutting ridge (15) of a protrusion (16) which limits the calibrated cavity of the mould (14) on the internal face of the extruded section piece. As the mould (14) pivots, the excess polymer material is pushed back in the direction of the periphery of the window glass and beyond this periphery.

  • Patent number: 6017038
    Abstract: To prevent abnormal sounds made by the vibrations of the tip of a seal lip of the molding for a window plate of a vehicle which are created when the air is sucked out from the inner cavity by the difference in pressure between the inside and the outside of the seal lip when the vehicle runs at high speeds, a seal lip body 4a extends in the direction of a vehicle body panel P from the leg of the molding 1 for a window plate and a folded-back lip 4b is consecutively integrally formed such that it folded back in the opposite inward direction from the tip of the seal lip body 4a into the cavity 5 between itself and the vehicle body panel P and extends along the vehicle body panel P. When the vehicle runs at high speeds, even if the seal lip 4a is moved up by the difference in pressure between the inside and the outside of the seal lip body 4a, the folded-back lip 4b is pressed on the vehicle body panel P and thus the air does not leak from the cavity 5.

  • Patent number: 5979974
    Abstract: A watertight and airtight seal is useful for use between two structures having relative movement therebetween. The seal apparatus includes a first adhesive bead (38) disposed on a first structural member (12) and a second adhesive bead (44) disposed on a second structural member (22). An elastomeric member (30) includes a first flange (34) portion bonded to the first adhesive bead and a second flange portion (36) bonded to the second adhesive bead (44). The elastomeric member also includes a flexible portion disposed between the first and second flange portions, this flexible portion being operative to freely flex during relative motion between the first and second structural members. This flexibility substantially reduces stress otherwise imparted on the first and second adhesive beads during such movements in the absence of the flexible portion, thereby improving the durability of the seal.

  • Patent number: 5961174
    Abstract: An auto window molding attached to extend from a peripheral edge of the window into a gap in which it has a U-shaped configuration serving as a flow passage to drain off rain and melting snow. The free end or leg of the U-shape is provided with a first encountered concave shape and a next encountered convex shape which keeps the flow passage open when the molding is bent around the small radius corners of the window, due to abutment at the change in curvature of the leg with the U-shape that is on the window peripheral edge, which abutment limits the inward movement of the leg as could result in the closing of the flow passage.

  • Patent number: 5935356
    Abstract: In the processes for the production and installation of a pane of glass with a frame, in particular on a vehicle part, the frame is produced as a plastics molding in the form of a closed ring. In these processes, a first bearing surface for the pane of glass and an adhesive bonding surface for the application of an adhesive are formed integrally on one side of the frame, and a second bearing surface for placing against the vehicle part is formed integrally on one of the other sides of the frame. In addition, either a retaining element running around along the frame or a number of anchoring elements or a second adhesive bonding surface for the application of a second adhesive are formed integrally on one of the other side of the frame. The frame may first of all be connected permanently to the pane of glass using an adhesive and then connected removably or permanently to the vehicle part together with the pane of glass by means of the retaining element or the anchoring elements or the second adhesive.

  • Patent number: 5885670
    Abstract: The Conventional Direct Glazing invention concerns a process for securing fixed panes of inorganic or organic glass to vehicles or parts thereof, in which flexible structural components and or sealing strips are prefitted by a weld strip between them and the pane by thermally activating the weld strip and thus producing a seaming effect on the pane, and pane modules thus produced. A pane module thus produced can subsequently be conventionally fitted to the coachwork on the assembly line using fitting strings without any further auxiliaries and working process. Owing to the material used for the flexible structural component and or sealing strip, the sealing quality corresponds to that of direct glazing. If the residual heat from the manufacture of the pane is used as the activation heat for the sealing strip, considerable economies are achieved in the manufacturing process for the pane module.
