Abstract
Abstract A channel-shaped sealing strip, such as for clamping over the metal flange of a vehicle door opening so as to embrace, protect and decorate the flange, comprises a flexible U-shaped metal carrier covered in elastomeric material, the elastomeric material having an insert of softer elastomeric material running along the inside of the base of the channel to seal against the edge of the flange. The strip may also have longitudinal gripping ribs running along opposite inside facing side walls of the channel to grip annd seal against the flange sides. A sealing part of softer elastomeric material may run on and along the outside of one wall of the channel. In a modification, where such a sealing part, and gripping ribs, are provided, the insert is omitted.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
110 words
A channel-shaped sealing strip, comprising U-shaped metal carrier means, channel-shaped elastomeric material enclosing the carrier means, a linear insert of softer elastomeric material in and extending through the thickness of the channel-shaped elastomeric material and running along the base of the channel and being proud of the inside surface of the base, the said insert being of cellular elastomeric material and being formed integrally with the remainder of the elastomeric material, and a sealing part attached to and running along the outside of the channel, the sealing part being made of cellular elastomeric material formed integrally with and being an extension of the cellular elastomeric material of the linear insert.
Claim 2
Dependent Claim
110 words
A channel-shaped sealing strip, comprising U-shaped metal carrier means, channel-shaped elastomeric material enclosing the carrier means, a linear insert of softer elastomeric material in and extending through the thickness of the channel-shaped elastomeric material and running along the base of the channel and being proud of the inside surface of the base, the said insert being of cellular elastomeric material and being formed integrally with the remainder of the elastomeric material, and a sealing part attached to and running along the outside of the channel, the sealing part being made of cellular elastomeric material formed integrally with and being an extension of the cellular elastomeric material of the linear insert.
Claim 3
Dependent Claim
39 words
A strip according to claim 1, in which the said insert, where it is proud of the inside surface of the base of the channel, is trough-shaped to present a concave surface facing towards the mouth of the channel.
Claim 4
Dependent Claim
38 words
A strip according to claim 1, in which the insert, where it is proud of the inside surface of the base of channel, is tubular, with the axis of the tube running along the length of the channel.
Claim 5
Dependent Claim
20 words
A strip according to claim 1, including a sealing part running along the outside of the base of the channel.
Claim 6
Dependent Claim
20 words
A strip according to claim 1, including one or more gripping ribs on the inside facing walls of the channel.
Claim 7
Dependent Claim
20 words
A strip according to claim 5, in which the ribs on opposite sides of the channel are of different hardness.
Claim 8
Dependent Claim
29 words
A strip according to claim 5, in which at least one of the ribs is of the same consistency and hardness as the elastomeric material of the channel sides.
Claim 9
Dependent Claim
30 words
A strip according to claim 5, in which at least one of the ribs is of the same consistency as but softer than the elastomeric material of the channel sides.
Claim 10
Dependent Claim
18 words
A strip according to claim 5, in which at least one of the ribs is of cellular form.
