Abstract
Abstract A window assembly includes a transparent glass sheet and gaskets formed by curing a polymeric gasket material in situ on the glass sheet to encapsulate a marginal peripheral edge portion thereof. A glass sheet to be utilized in a vehicle door has a front edge, rear edge and a lower edge to each of which is adhered such a gasket. In addition, a bracket means for attachment to a scissor linkage for raising and lowering the window can be secured to the lower edge of the window. The gaskets are formed in a mold with the transparent sheet and bracket means, typically by a reaction injection molding process. Each of the front and rear gaskets may have a flange portion thereon for insertion in an opening in a gasket attached to a frame of the window opening in the vehicle door.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
182 words
A window assembly comprising: a sheet of transparent material; a bracket means positioned along a first portion of the peripheral edge of said transparent sheet; and a gasket composed of a synthetic polymer and including (a) a first member extending along said first portion of the peripheral edge of said transparent sheet between said bracket means and said sheet, said first member adhered to both said sheet and said bracket means for securing said bracket means relative to said sheet, (b) a second member spaced from said first member and extending along and adhered to a second portion of the peripheral edge of said sheet for providing an exposed peripheral sealing surface, and (c) a rib extending along and adhered to the peripheral edge of said sheet connecting said first member of said gasket to said second member, said gasket having been polymerized in situ adjacent said bracket means and said peripheral edge portions of said sheet and having assumed through the autogenous mechanism incident to its polymerization and cure while confined, intimate contact with the portions to which it is adhered.
Claim 2
Dependent Claim
182 words
A window assembly comprising: a sheet of transparent material; a bracket means positioned along a first portion of the peripheral edge of said transparent sheet; and a gasket composed of a synthetic polymer and including (a) a first member extending along said first portion of the peripheral edge of said transparent sheet between said bracket means and said sheet, said first member adhered to both said sheet and said bracket means for securing said bracket means relative to said sheet, (b) a second member spaced from said first member and extending along and adhered to a second portion of the peripheral edge of said sheet for providing an exposed peripheral sealing surface, and (c) a rib extending along and adhered to the peripheral edge of said sheet connecting said first member of said gasket to said second member, said gasket having been polymerized in situ adjacent said bracket means and said peripheral edge portions of said sheet and having assumed through the autogenous mechanism incident to its polymerization and cure while confined, intimate contact with the portions to which it is adhered.
Claim 3
Dependent Claim
13 words
The window assembly according to claim 1 wherein said sheet material is glass.
Claim 4
Dependent Claim
13 words
The window assembly according to claim 1 wherein said bracket means is metal.
Claim 5
Dependent Claim
16 words
The window assembly according to claim 1 wherein said gasket is formed of an elastomeric material.
Claim 6
Dependent Claim
15 words
The window assembly according to claim 4 wherein said elastomeric material is a polyurethane material.
Claim 7
Dependent Claim
190 words
A window assembly comprising: a sheet of transparent material; a bracket means positioned along a first portion of the peripheral edge of said transparent sheet; and a gasket composed of a synthetic polymer and including (a) a first member extending along said first portion of the peripheral edge of said transparent sheet between said bracket means and said sheet, said first member adhered to both said sheet and said bracket means for securing said bracket means relative to said sheet, (b) second members spaced from said first member and from each other and extending along and adhered to second portions of the peripheral edge of said sheet for providing exposed peripheral sealing surfaces, and (c) a pair of ribs extending along and adhered to the peripheral edge of said sheet, each connecting said first member of said gasket to a respective one of said second members, said gasket having been polymerized in situ adjacent said bracket means and said peripheral edge portions of said sheet and having assumed through the autogenous mechanism incident to its polymerization and cure while confined, intimate contact with the portions to which it is adhered.
Claim 8
Dependent Claim
190 words
A window assembly comprising: a sheet of transparent material; a bracket means positioned along a first portion of the peripheral edge of said transparent sheet; and a gasket composed of a synthetic polymer and including (a) a first member extending along said first portion of the peripheral edge of said transparent sheet between said bracket means and said sheet, said first member adhered to both said sheet and said bracket means for securing said bracket means relative to said sheet, (b) second members spaced from said first member and from each other and extending along and adhered to second portions of the peripheral edge of said sheet for providing exposed peripheral sealing surfaces, and (c) a pair of ribs extending along and adhered to the peripheral edge of said sheet, each connecting said first member of said gasket to a respective one of said second members, said gasket having been polymerized in situ adjacent said bracket means and said peripheral edge portions of said sheet and having assumed through the autogenous mechanism incident to its polymerization and cure while confined, intimate contact with the portions to which it is adhered.
