Abstract

An automotive window assembly of the type having a stationary window assembly insertable onto a peripheral flange of a rabbet flanged window aperture which is formed in an automotive vehicle body. The window assembly is designed to be adhesively secured to the automobile body after being mounted on the peripheral flange. The window assembly includes a plurality of cup-shaped retention elements which have inner sides fixedly secured to the inner peripheral surface of the window assembly. Each retention element has a resilient outer side, and a generally perpendicular, outwardly extending stem joined at one end thereof to the resilient outer side of each of the plurality of retention elements. The stem is inwardly deflectable about the joint formed at the one end thereof and the resilient outer side of the cup-shaped retention element. The stem includes a plurality of teeth for engaging the peripheral flange of the window aperture, thereby retaining the window assembly on the motor vehicle upon the application and curing of the adhesive.

Claims

1. A retention system for an automotive window of the type having a window assembly insertable onto a peripheral flange of a flanged window aperture formed in an automotive vehicle body, said window assembly to be adhesively secured thereto, the window assembly being positioned with respect to the aperture by a plurality of retention elements mounted on the window assembly and operatively disposed between the window assembly and the aperture, said retention system comprising:

a suction cup-shaped base portion having an inner side adapted to be fixedly secured to an inner peripheral surface of the window assembly and having a resilient outer side;

a generally perpendicular outward extending stem attached at a joint formed between a first end of said stem and said resilient outer side of said cup-shaped base portion, said stem having a free end deflecting toward the interior of the flanged window aperture upon engagement therewith about said joint formed between said first end thereof by outwardly deforming said resilient outer side of said cup-shaped base portion in a direction toward the interior of the window aperture;

means integral with said generally perpendicular outwardy extending stem for lockingly engaging the peripheral flange of the flanged window aperture; and

curable adhesive means for application to said suction shaped base portion, prior to the placement thereof on said window assembly, said adhesive means allowing movement of said base portion with respect to said window assembly prior to curing, and fixing said base portion with respect to said window assembly after curing.

2. The automotive window retention system as set forth in claim 1 wherein said stem includes a tapered abutment portion on the free end thereof adapted to engage the peripheral flange of the flanged window aperture, and, upon engagement therewith during the insertion of the window assembly into the flanged window aperture, causing the deflection of said stem toward the interior of the window aperture.

3. The automotive window retention system as set forth in claim 1 wherein said means integral with said outwarldy extending stem for lockingly engaging the peripheral flange includes locking teeth formed on a surface of said stem, said locking teeth extending in a direction outwardly of said flanged window aperture and extending from said first end to said second end of said stem.

4. The automotive window retention system as set forth in claim 1, wherein the outer resilient side of said cup-shaped base portion of said retention element is convex.

5. The automotive window retention system as set forth in claim 1, wherein the inner side of said cup-shaped base portion of said retention element is concave prior to being mounted to the window assembly.

6. The automotive window retention system as set forth in claim 1 wherein said outwardly extending stem is made of a resiliently deformable material.

7. The automotive window retention system as set forth in claim 1 wherein said suction cup-shaped base portion is initially fixedly secured to said inner peripheral surface of the window assembly by suction generated by deforming said inner side of said base portion against said inner peripheral surface of said window assembly and permanently fixedly secured thereto by an adhesive.
