Abstract
Abstract An improved pile weather strip having one or more rows of pile formed from substantially identical, closely packed monofilament yarns of non-circular cross-section whereby improved resistance to infiltration of foreign material such as air and moisture is achieved. Each monofilament yarn fiber is preferably of an enlarged X-shaped cross-section.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
148 words
A pile weather strip for sealing the space between relatively movable members, comprising: a longitudinally extending backing strip; a longitudinally extending first row of body fibers, each body fiber characterized by a first maximum cross-sectional dimension and having one end attached to said backing strip and its opposite free end projecting from said backing strip; and a second longitudinally extending row of substantially identical nestable monofilament barrier fibers adjacent said first row of body fibers, each monofilament barrier fiber having a non-circular cross-sectional shape characterized by at least one cross-sectional dimension greater than the maximum cross-sectional dimension of said body fibers and generally longitudinally aligned along said backing strip and having one end of said barrier fiber attached to said backing strip and its opposite free end projecting from said backing strip said row of barrier fibers operative to substantially reduce the infiltration of air and moisture thereacross.
Claim 2
Dependent Claim
148 words
A pile weather strip for sealing the space between relatively movable members, comprising: a longitudinally extending backing strip; a longitudinally extending first row of body fibers, each body fiber characterized by a first maximum cross-sectional dimension and having one end attached to said backing strip and its opposite free end projecting from said backing strip; and a second longitudinally extending row of substantially identical nestable monofilament barrier fibers adjacent said first row of body fibers, each monofilament barrier fiber having a non-circular cross-sectional shape characterized by at least one cross-sectional dimension greater than the maximum cross-sectional dimension of said body fibers and generally longitudinally aligned along said backing strip and having one end of said barrier fiber attached to said backing strip and its opposite free end projecting from said backing strip said row of barrier fibers operative to substantially reduce the infiltration of air and moisture thereacross.
Claim 3
Dependent Claim
18 words
A pile weather strip according to claim 1 wherein said non-circular monofilament yarn fiber is of solid cross-section.
Claim 4
Dependent Claim
18 words
A pile weather strip according to claim 1 wherein said non-circular monofilament yarn fiber is of hollow cross-section.
Claim 5
Dependent Claim
20 words
A pile weather strip according to claim 1 wherein each of said monofilament yarn fibers has a substantially X-shaped cross-section.
Claim 6
Dependent Claim
14 words

Claim 7
Dependent Claim
14 words
A pile weather strip according to claim 4 wherein said X-shaped cross-section is hollow.
Claim 8
Dependent Claim
17 words
A pile weather strip according to claim 4 wherein said body fiber is a multifilament yarn fiber.
Claim 9
Dependent Claim
25 words
The weatherstrip of claim 1 wherein said second longitudinally extending row of barrier fibers comprises a plurality of body fibers intermixed with said barrier fibers.
