Glass run seal testing machine
First Claim
1. An apparatus for testing glass window seals of the type used in powered automotive windows, comprising:
- a frame adapted to receive a piece of test sized piece of window glass driven in a repetitive motion simulating operation in a powered automotive window, the frame comprising a pair of seal-holding members adapted to removably mount a pair of window seal segments in a position engaging the window glass in a manner simulating a sliding seal with the window glass in a powered automotive window, the window seal segments being taken from the group consisting of glass run seals and belt seals, the seal holding members having opposing members for capturing said window seal segments wherein the distance between said opposing members is adjustable to removably mount different pairs of window seal segments and to vary tolerances with which the window seals engage the window glass.

Abstract
A window seal testing machine for seals of the type used in powered automotive windows, the testing machine comprising an adjustable frame simulating a portion of a powered automotive window, the frame being adapted to receive one or more sets of window seals and a piece of window glass therein to simulate the sealing relationship between the seals and window glass in an actual automotive window. The testing machine further includes a drive mechanism for repetitively cycling the window glass through the frame and seals to simulate actual window operation over hundreds or thousands of cycles. The entire machine is preferably self-contained and portable, and the frame is further adjustable to be adapted to test different sets of seals and types of window glass.

13. An apparatus for testing glass window seals of the type used in powered automotive windows, comprising;
a frame adapted to receive a test sized piece of window glass driven in a repetitive motion simulating operation in a powered automotive window, the frame comprising a pair of seal-holding members adapted to removably mount a pair of window seal segments in a position engaging the window glass in a manner simulating a sliding seal with the window glass in a powered automotive window, the window seal segments being taken from the group consisting of glass run seals and belt seals, the seal holding members being adjustable to removeably mount different pairs of window seal segments and to vary tolerances with which the window seal segments engage the window glass, wherein the seal holding members comprise a pair of pillar-simulating members each adapted to hold a glass run seal wherein the pillar-simulating members each comprise a pair of glass run channel sides adjustably spaced relative to one another and located to overlie side edges of the window glass. - View Dependent Claims (14)

15. A method for testing glass window seals of the type used in powered automotive windows, comprising the following steps:
-
mounting one or more segments of actual window seals in an adjustable open-ended frame simulating powered automotive window channel portions from the group consisting of glass run channels and belt strips;
mounting a test-sized piece of window glass in the frame in engagement with the window seal segments in a manner simulating an actual sliding seal in a powered automotive window;
driving the window glass in the frame in a repetitive motion simulating actual powered automotive window operation cycles; and
,observing wear on the window seal segments over a period of many cycles. - View Dependent Claims (16, 17, 18)
