Abstract
Abstract A sealing strip for a vehicle door opening has a generally channel-shaped gripping part supporting a tubular sealing part. Initially, the side walls of the channel of the gripping part are splayed apart so as to enlarge the mouth of the channel. This eases the application of the gripping part to the normal mounting flange surrounding the vehicle door opening. The flange can pass freely between gripping lips on the opposite inside walls of the gripping part. A suitable tool is then employed to press the side walls of the channel towards each other so as to render them substantially parallel, thus pressing the lips into gripping and sealing contact with the flange surfaces, this configuration being therefore resiliently maintained by a metal carrier embedded in the gripping part. One of the sealing lips is particularly advantageous for secondary sealing purposes because it is directed outwardly of the mouth of the channel, unlike the other lips. The initial outward direction of this lip is maintained after fitment of the strip of the flange, because of the initial splaying apart of the side walls of the channel.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
207 words
A channel-shaped sealing or finishing strip for fitment to a mounting flange running around an opening closable by a closure member, comprising longitudinally extending flexible material in which is embedded a metal carrier, the flexible material being generally channel-shaped in cross-section and defining a lip extending longitudinally of the channel on the inside of one of the sidewalls thereof and directed obliquely from that side wall towards the mouth of the channel from the inside of the channel, the carrier also being generally channel-shaped in cross-section and embedded within the channel-shaped flexible material, the sidewalls of the channel-shaped flexible material and the carrier being initially splayed apart to facilitate mounting on the flange and to prevent any contact between the distal edge of the lip and the flange bending the lip inwardly of the channel, the splayed-apart side walls being adapted to be thereafter pressed towards each other, by the application of force, into a subsequently resiliently retaining configuration embracingly gripping the mounting flange and with the distal edge of the lip pressed into sealing engagement with the mounting flange, the strip being retained on the mounting flange solely by the resilience of the carrier and the frictional contact between the flexible material and the mounting flange.
Claim 2
Dependent Claim
207 words
A channel-shaped sealing or finishing strip for fitment to a mounting flange running around an opening closable by a closure member, comprising longitudinally extending flexible material in which is embedded a metal carrier, the flexible material being generally channel-shaped in cross-section and defining a lip extending longitudinally of the channel on the inside of one of the sidewalls thereof and directed obliquely from that side wall towards the mouth of the channel from the inside of the channel, the carrier also being generally channel-shaped in cross-section and embedded within the channel-shaped flexible material, the sidewalls of the channel-shaped flexible material and the carrier being initially splayed apart to facilitate mounting on the flange and to prevent any contact between the distal edge of the lip and the flange bending the lip inwardly of the channel, the splayed-apart side walls being adapted to be thereafter pressed towards each other, by the application of force, into a subsequently resiliently retaining configuration embracingly gripping the mounting flange and with the distal edge of the lip pressed into sealing engagement with the mounting flange, the strip being retained on the mounting flange solely by the resilience of the carrier and the frictional contact between the flexible material and the mounting flange.
Claim 3
Dependent Claim
55 words
A strip according to claim 1, including at least one further lip made of flexible material running along one inside side wall of the channel and being pressed into contact with the side of the mounting flange upon application of the said force, this further lip being directed obliquely towards the base of the channel.
Claim 4
Dependent Claim
14 words
A strip according to claim 1, in which the flexible material is extruded material.
Claim 5
Dependent Claim
23 words
A strip according to claim 1, including a sealing part made of flexible sealing material mounted on an outside wall of the channel.
Claim 6
Dependent Claim
32 words
A strip according to claim 1, including a sealing part made of flexible sealing material mounted on the outside of that side wall of the channel whose inside carries the said lip.
Claim 7
Dependent Claim
199 words
A sealing strip, comprising a generally channel-shaped gripping part made of flexible extruded material in which is embedded a channel-shaped metal carrier, sealing and gripping lips mounted on the inside facing side walls of the channel, and a soft tubular sealing section mounted on and running along an outside side wall of the channel of the gripping part, one of the said lips adjacent the mouth of the channel being directed obliquely from the respective side wall of the channel towards the mouth of the channel from inside the channel, the side walls of the gripping part being initially in splayed apart configuration so as to diverge and provide an enlarged channel mouth for receiving a mounting flange and being adapted for subsequent forced movement towards each other into a generally parallel and thereafter resiliently retained configuration for bringing the lips into gripping and sealing contact with the sides of the mounting flange, the said one lip being directed towards the mouth of the channel in both configurations of the side walls, the strip being retained on the mounting flange solely by the resilience of the carrier and the frictional contact between the flexible material and the mounting flange.
Claim 8
Dependent Claim
199 words
A sealing strip, comprising a generally channel-shaped gripping part made of flexible extruded material in which is embedded a channel-shaped metal carrier, sealing and gripping lips mounted on the inside facing side walls of the channel, and a soft tubular sealing section mounted on and running along an outside side wall of the channel of the gripping part, one of the said lips adjacent the mouth of the channel being directed obliquely from the respective side wall of the channel towards the mouth of the channel from inside the channel, the side walls of the gripping part being initially in splayed apart configuration so as to diverge and provide an enlarged channel mouth for receiving a mounting flange and being adapted for subsequent forced movement towards each other into a generally parallel and thereafter resiliently retained configuration for bringing the lips into gripping and sealing contact with the sides of the mounting flange, the said one lip being directed towards the mouth of the channel in both configurations of the side walls, the strip being retained on the mounting flange solely by the resilience of the carrier and the frictional contact between the flexible material and the mounting flange.
