Abstract

ABSTRACT OF THE DISCLOSURE
A channel-shaped sealing strip for mounting around an opening of a vehicle body is shown, having a channel-shaped gripping portion for mounting on and embracing a mounting flange running around the opening, and a longitudinally extending seal positioned to seal against the closure member of the opening. The gripping portion is made of flexible material having embedded within it a reinforcing carrier and defines three large ribs on one inside wall of the channel and frou smaller ribs on the other inside wall. The inner-most rib on one side wall defines in conjunction with the corresponding rib on the other side wall, and with the base of the channel, a cavity for receiving a mastic sealant which in use seals against the distal edge of the mounting flange.
A longitudinally extending sealing lip is mounted on the channel adjacent its mouth and extends outwardly and away from the mouth for engaging a drain channel. This lip has a tear-off cord by means of which the lip can be manually pulled in a predetermined direction during fitment so as to locate it in the drain channel.

BACKGROUND OF THE INVENTION

The invention relates to sealing and finishing strips such as, for example, to channel-shaped strips supporting a seal and arranged to embrace a flange or the like in a vehicle body.

S~MMARY OF THE INVENTION

According to the invention, there is provided a channel-shaped strip for embracing a mounting flange or the like in use and made of channel-shaped flexible material having ribs running along the inside of the channel on opposite side walls thereof, there being a plurality of ribs on each such side wall, the innermost rib of each side wall extending substantially perpendicular from its respective side wall so that its distal edge makes contact with the distal edge of the innermost rib on the opposite side wall when the strip is not motmted on the said flange or the like thereby to define, with the base of the channel, a cavity for receiving a mastic sealant for sealing against the distal edge of the mounting flange or the like in use, the other ribs extending obliquely to their respective side walls and being directed towards the base of the channel.

According to the invention, there is also provided a channel-shaped sealing strip for mount.ing around . ~ '~

~ 7'~

the luggage compartment opening of a vehicle body, com-prising a channel~shaped gripping portion for mounting on and embracing a mounting flange running around the said opening, and a longitudinally extending seal attached to the outside of the channel so as to be positioned, when the channel-shaped portion is mounted on the flange, whereby to seal against the lid of the opening, the channel-shaped portion being made of flexible material having embedded within it a reinforcing carrier and defining three ribs on one inside wall of the channel and four such ribs on the other inside wall, the innermost rib on each inside wall extending substantially perpendicular from its respective wall so that its distal edge makes contact with the distal edge of the innermost rib on the opposite wall when the strip is not mounted on the said flange whereby the innermost ribs define with the base of the channel a cavity for receiving a mastic sealant which in use seals against the distal edge of the mounting flange, the other said ribs exerting a gripping force on the mounting flange, the said three ribs being relatively larger than the said four ribs, and a longitudinally extending sealing lip mounted on the channel adjacent the mouth thereof and extending outwardly and away from the mouth for engaging a drain channel running around the said flange, the sealing lip having a tear-off protruding strip running along its length by means of which the sealing lip can be manually pulled in a predetermined direction during fitment so as to locate the sealing lip in the drain channel.

1 ~ ~Z 2 - 2a -DESCRIPTION OF THE DRAWING
Channel-shaped sealing strips embodying the invention will now be described, by way of example only, with reference to the accompanying diagrammatic drawing which is a cross-section through one form of the sealing strip.

DESCRIPTION OF PREFERRED EMBODIMENTS
The sealing lip to be described is intended for mounting around the luggage compartment opening on a vehicle body, though is not restricted to such use. Such luggage compartment openings normallyhave-a flange (shown dotted at 3) running around them which is generally up-standing and adjacent to the drain channel (shown dotted , ,-,.

_ 3 _ ~ 1 7 2 290 at 4) i-or draining away water.
As shown, the sealing strip has a channel-shaped gripping portion 5 on which is mounted a sealing portion 6. In use, the gripping p~rtion 5 is mounted on and embraces the flange and thereby positions the sealing portion 6 to run around the opening so that the lid of the luggage compartment closes onto it, partially compresslng it and thus providing a sealing function.
Advantageously, therefore, the sealing portion 6 is made of flexible resilient material such as sponge rubber. The gripping portion 5 is constructed of flexible material 7 such as rubber or plastics and advantageously has embedded within it a reinforcing support or earrier 8. The carrier 8 is intended to be sufficiently flexible to allow the strip to be mounted in position but is also sufficiently resilient to stiffen and reinforce the gripping portion 5 and help to increase the force with which it is retained on the mounting flange. The carrier may have any suitable form. It may, for example, be made of metal. In one possible form, it comprises a series of side-by-side U-shaped elements which are interconnected by links or possibly completely disconnected.
Instead, for example, it could be in the form of a corrugated channel.Inanother form, it can be made of wire such as wire looped back and forth across the width of the channel.
However, other forms of carrier are also possible.
The flexi.ble material 7 of the gripping portion 5 is formed with inwardly directed ribs, therc being li72290 three such ribs 10, 12, 14 on one inside wall of the channel and four, smaller, ribs 16, 18, 20 and 22 on the opposite side. The ribs run along the length of the channel.
In use, when the gripping portion 5 is pressed onto the flange 3, the ribs on opposite sides of the channel are forced apart to allow entry of the flange and press against the sides of the flange. The ribs 10, 12, 16, 18 and 20 are designed to exert a gripping and sealing force on the flange. In doing so, t'ney help to resist removal of the strip from the flange and also help to prevent water or moisture from entering the luggage compartment by running around the flange on the inside of the channel.
The ribs 10 to 22 may be fo~med integrally with the flexible material 7 such as by an extrusion process.
They need not be of the same hardness as the flexible material 7 and it may in fact be advantageous for them to be made of softer material than the material 7 because (in the case of ribs 10, 12, 16, 18 and 20) this is found to improve their sealing ar.d gripping action.
The sealing portion 6 may also be extruded simultan-eously with the material 7 (and the lips 10 to 22) or it may be formed separately and secured to the gripping section 5 as by means of adhesive.
In addition, a suitable mastic sealant is placed in the base of the channel, at 24, to provide an additional seal and water barrier, so that the distal edge of the flange presses into this mastic.

7;~Z90 The provision of the relatively thin top ribs 14 and 22 is advantageous because they define a cavity, at 24, within which the mastic is located, and help to prevent the mastic from running down onto the main gripping ribs 10, 12 16, 18 and 20. Without the provisionof such rihs 14, 22, it is found that the mastic does have this tendency to run onto the main gripping ribs, reducing their gripping force. The ribs 14 and 22 also enable a smaller quantity of mastic sealant to be used. These ribs are primarily designed for mastic retention and exert substantially no gripping force on the flange 3.
The arrangement of the ribs so that there are three relatively large ribs on one side of the channel and four relatively small ones on the o~her side is advantageous in giving additional stability to the gripping section 5 when mounted on the flange.
The lower large gripping rib 10 has a cut-out 26 to increase its flexibility.
In addition,the gripping portion 5 has a downwardly and outwardly extending longitudinal sealing lip 28 which may advantageously be formed integrally with the material 7.
In use, when the gripping portion 5 is mounted on the mounting flange, tlle sealing lip 28 extends into the drain channel 4 which runs around the luggage compartment opening.
It is important that the lip 28 does not become inadvertently tucked up inside the gripping portion 5 when the gripping portion is forced onto the flange 3. In order to guard against this possibility, the lip 28 is provide~d with a tear-~ 1~7~ ~ 9~

off cord 32 running along the length of the lip. Thiscord is integrally formed with the material of the lip 38 but is attached to it by a relatively weak neck 34 and the cord may extend beyond the length of the lip 28. In use, the fitter grips the cord 32 and uses it to pull the distal edge 36 of the lip 28 outwardly and upwardly - and thus away from the mouth of the gripping portion 5, and, simultaneously, tears the cord 32 off via the weakened beck 34. In this way, the lip 28 is positively located within the drain channel 4 at the correct location, as shown dotted in the drawing, so as to provide most effective sealing. At the same time, the cord 32 is removed so as not to impede sealing.
