Abstract
Abstract With the object of providing a glass run channel which can accommodate the curvature in both front elevation and plan, and also some degree of twisting, in this invention a glass run channel comprises a metal core of general S shape, the metal core having a continuous unbroken strip and a plurality of transversely extending slits forming between them bars or ribs extending transversely from the unbroken strip, the core being covered with an elastomer.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
97 words
A motor vehicle glass run channel having a generally S-shaped cross-section, comprising a metal core covered with an elastomer outer casing, said cross-section defining a relatively small channel portion and a relatively large channel portion, said small channel portion having inwardly directed resilient barbs and said large channel portion having inwardly directed resilient lips, said barbs and lips being of elastomer, said core including a continuous unbroken strip extending longitudinally, and a plurality of bars extending transversely from the strip and spaced by slots, and said unbroken strip lying between limbs which flank said small channel portion.
Claim 2
Dependent Claim
97 words
A motor vehicle glass run channel having a generally S-shaped cross-section, comprising a metal core covered with an elastomer outer casing, said cross-section defining a relatively small channel portion and a relatively large channel portion, said small channel portion having inwardly directed resilient barbs and said large channel portion having inwardly directed resilient lips, said barbs and lips being of elastomer, said core including a continuous unbroken strip extending longitudinally, and a plurality of bars extending transversely from the strip and spaced by slots, and said unbroken strip lying between limbs which flank said small channel portion.
Claim 3
Dependent Claim
39 words
A motor vehicle glass run channel according to claim 1 wherein the transversely extending bars of the core extend into the limbs which flank the small channel portion and also into an outermost flange of the large claimed portion.
Claim 4
Dependent Claim
27 words
A motor vehicle glass run channel according to claim 2 wherein the outermost surface of the outermost flange is a surface which has been ground and painted.
Claim 5
Dependent Claim
26 words
A motor vehicle glass run channel according to claim 1 wherein each of the inwardly directed resilient lips has a glass engaging surface of flock material.
Claim 6
Dependent Claim
51 words
A motor vehicle glass run channel according to claim 1 wherein the transverse bars of the core extend into the limbs which flank the small channel portion but not into an outermost flange of large channel portion, said outermost flange being of harder elastomer than the remainder of the outer casing.
Claim 7
Dependent Claim
24 words
A motor vehicle glass run channel according to any one of claims 2, 4, 3, 5 or 1 wherein said elastomer is EPDM rubber.
Claim 8
Dependent Claim
139 words
A motor vehicle glass run channel comprising: a metal core covered with an elastomer outer casing of a generally S-shaped cross-section said glass run channel being shaped such that said cross-section thereof defines a relatively small channel portion and a relatively large channel portion, said large channel portion opening in direction generally opposite to said small channel portion and each said channel portion having a bottom wall portion extending between limbs thereof, said small channel portion having inwardly directed resilient barbs and said large channel portion having inwardly directed resilient lips, said barbs and lips being of elastomer, said core including a continuous unbroken strip extending longitudinally, and a plurality of bars extending transversely from the strip and spaced by slots, and said unbroken strip lying in the region of said bottom wall portion of said small channel portion.
Claim 9
Dependent Claim
139 words
A motor vehicle glass run channel comprising: a metal core covered with an elastomer outer casing of a generally S-shaped cross-section said glass run channel being shaped such that said cross-section thereof defines a relatively small channel portion and a relatively large channel portion, said large channel portion opening in direction generally opposite to said small channel portion and each said channel portion having a bottom wall portion extending between limbs thereof, said small channel portion having inwardly directed resilient barbs and said large channel portion having inwardly directed resilient lips, said barbs and lips being of elastomer, said core including a continuous unbroken strip extending longitudinally, and a plurality of bars extending transversely from the strip and spaced by slots, and said unbroken strip lying in the region of said bottom wall portion of said small channel portion.
