Abstract
Abstract A window guide arrangement for sealing and guiding a movable window pane of an automobile consists of a channel-shaped gasket of resilient material, such as rubber or plastics, and a mounting channel for the gasket which is generally U-shaped in cross section. Longitudinal ribs on the outer flange surfaces of the gasket abut against shoulders on the flanges of the mounting channel to secure the gasket while leaving a free space between the respective web portions of the gasket and mounting channel.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
276 words
A guide arrangement for sealing and guiding a movable pane comprising: a. an elongated mounting channel of approximately U-shaped cross section including a web and two flanges extending from said web in a common direction spaced relationship, 1. a first portion of each flange being adjacent said web, and a second portion being remote from said web and including a free edge portion, 2. said web and said flanges bounding a cavity in said channel, 3. said second portions being offset from said first portions outward of said channel so as to define a shoulder one each flange in said cavity; b. an elongated channel-shaped gasket of resilient material in said cavity, 1. said gasket having a web portion, two flange portions extending from said web portion in a common direction, and a longitudinal rib projecting from each flange portion in a direction away from the other flange portion, 2. each rib being offset from an associated one of said shoulders outwardly of said cavity for abutting engagement with the associated shoulder when said gasket moves inward of said cavity, 3. said web and said web portion bounding an air space therebetween when said ribs abuttingly engage the associated shoulder; and c. abutment means projecting from each of said flanges toward the other flange and engaging one of said ribs when said gasket moves outward of said cavity and said one rib is moved thereby away from said aubtting engagement with the associated shoulder, the spacing of said shoulder and of said abutment means being greater than the dimension of said rib in the direction of movement of said gasket inward and outward of said cavity.

Dependent Claim
276 words
A guide arrangement for sealing and guiding a movable pane comprising: a. an elongated mounting channel of approximately U-shaped cross section including a web and two flanges extending from said web in a common direction spaced relationship, 1. a first portion of each flange being adjacent said web, and a second portion being remote from said web and including a free edge portion, 2. said web and said flanges bounding a cavity in said channel, 3. said second portions being offset from said first portions outward of said channel so as to define a shoulder one each flange in said cavity; b. an elongated channel-shaped gasket of resilient material in said cavity, 1. said gasket having a web portion, two flange portions extending from said web portion in a common direction, and a longitudinal rib projecting from each flange portion in a direction away from the other flange portion, 2. each rib being offset from an associated one of said shoulders outwardly of said cavity for abutting engagement with the associated shoulder when said gasket moves inward of said cavity, 3. said web and said web portion bounding an air space therebetween when said ribs abuttingly engage the associated shoulder; and c. abutment means projecting from each of said flanges toward the other flange and engaging one of said ribs when said gasket moves outward of said cavity and said one rib is moved thereby away from said aubtting engagement with the associated shoulder, the spacing of said shoulder and of said abutment means being greater than the dimension of said rib in the direction of movement of said gasket inward and outward of said cavity.
Claim 3
Dependent Claim
11 words
said web and said flanges bounding a cavity in said channel,
Claim 4
Dependent Claim
11 words
said web and said flanges bounding a cavity in said channel,
Claim 5
Dependent Claim
30 words
each rib being offset from an associated one of said shoulders outwardly of said cavity for abutting engagement with the associated shoulder when said gasket moves inward of said cavity,
Claim 6
Dependent Claim
30 words
each rib being offset from an associated one of said shoulders outwardly of said cavity for abutting engagement with the associated shoulder when said gasket moves inward of said cavity,
Claim 7
Dependent Claim
21 words
A guide arrangement as set forth in claim 1, further comprising a metallic reinforcing strip member embedded in said web portion.
Claim 8
Dependent Claim
95 words
said web and said web portion bounding an air space therebetween when said ribs abuttingly engage the associated shoulder; and c. abutment means projecting from each of said flanges toward the other flange and engaging one of said ribs when said gasket moves outward of said cavity and said one rib is moved thereby away from said aubtting engagement with the associated shoulder, the spacing of said shoulder and of said abutment means being greater than the dimension of said rib in the direction of movement of said gasket inward and outward of said cavity.
Claim 9
Dependent Claim
95 words
said web and said web portion bounding an air space therebetween when said ribs abuttingly engage the associated shoulder; and c. abutment means projecting from each of said flanges toward the other flange and engaging one of said ribs when said gasket moves outward of said cavity and said one rib is moved thereby away from said aubtting engagement with the associated shoulder, the spacing of said shoulder and of said abutment means being greater than the dimension of said rib in the direction of movement of said gasket inward and outward of said cavity.
Claim 10
Dependent Claim
25 words
A guide arrangement as set forth in claim 1, further comprising an antifriction coating on a face of said web portion intermediate said flange portions.
Claim 11
Dependent Claim
36 words
said second portions being offset from said first portions outward of said channel so as to define a shoulder one each flange in said cavity; b. an elongated channel-shaped gasket of resilient material in said cavity,
Claim 12
Dependent Claim
36 words
said second portions being offset from said first portions outward of said channel so as to define a shoulder one each flange in said cavity; b. an elongated channel-shaped gasket of resilient material in said cavity,
Claim 13
Dependent Claim
16 words

Claim 16
Dependent Claim
32 words
A guide arrangement as set forth in claim 6, further comprising an anti-friction coating on a face of each of said lip portions, said face being directed away from said web portion.
Claim 17
Dependent Claim
42 words
A guide arrangement as set forth in claim 6, further comprising a metallic reinforcing strip member embedded in said web portion and in said flange portion, said free edges projecting beyond said strip member in a direction away from said web portion.
