Mechanical interlock of curable sealant for modular framed auto glass parts
First Claim
1. A retention system for use with a curable adhesive for retaining a glass window pane supported on a flange of an automotive vehicle body, said retention system comprising:
- a moulding having an inner surface, an outer surface and a rear surface connecting said inner surface to said outer surface;
a glass window pane secured along a periphery thereof to the inner surface of said moulding;
the flange separated by a first spaced distance from the outer surface of said moulding and separated by a second spaced distance from said rear surface of said moulding;
means defining a shaped recess within said rear surface of said moulding, said shaped recess having an opening adjacent to said flange, said recess having an end wall located at a farther distance from said flange than said opening is located, and said recess having a sidewall connecting said opening to said end wall to define and interior portion, a cross section of said opening of the recess being smaller than a cross section of the interior portion;
a curable ashesive received within said first spaced distance between the outer surface of said moulding and said flange and received within said second spaced distance between the rear surface of said moulding and said flange, and also received within said shaped recess, so as to form a mechanical interlock between the curable adhesive, upon the curing thereof, and the shaped recess;
wherein said flange has an inner surface and an outer surface,a plurality of openings in said flange connecting said flange inner surface to said flange outer surface; and
a plurality of retaining means attached to said outer surface of said flange, each of said retaining means having an interior portion thereof in communication with each of said openings in said flange and receiving the curable adhesive, a cross section of said interior portion, of said retaining means, receiving the curable adhesive of each of said retaining means being greater than a cross section of said openings in said flange whereby a mechanical interlock is also formed between the curable adhesive, upon the curing thereof, and the outer surface of the said flange.

Abstract
The present invention provides a retention system for use with a curable adhesive for retaining a glass window pane supported on a flange of an automotive vehicle body. The system has a glass window pane secured to the inner surface of a moulding. A flange is spaced a first distance from the outer surface of the moulding, and this flange is spaced a second distance from the rear surface of the moulding. The rear surface of the molding contains a trapezoidal or conical shaped recess. A curable adhesive is received within the first spaced distance, the second spaced distance and the trapezoidal or conical shaped recess to form a mechanical interlock within this recess.
