Abstract

A system for sealing door and window openings on a motor vehicle body includes a sealing strip mounted on the vehicle body around the opening with a hollow tubular seal (16) made of soft material which extends at least partially around the opening and onto which the door and window glass closes. A tube (22) has one of its ends in communication with the interior of the tubular seal (16) and the other end mounted at the front of the vehicle and open to the atmosphere so that the motion of the vehicle forces air into the tube (22) to increase the air pressure within the tubular seal (16) and improve the sealing function at higher vehicle speeds. <IMAGE>

Description

SPECIFICATION Improvements in and relating to seals The invention relates to draught and weatherincluding seals, particularly for use on vehicles, and to systems incorporating such seals and vehicles incorporating such systems.
More specifically, the invention is applicable to seals which are mounted on vehicle bodies, such as motor vehicle bodies, around the door and window openings, and other openings (e.g. the luggage compartment opening) of the vehicle.
Known forms of such seals are tubular in shape and made of, for example, soft rubber or plastics material. They may be held in position by means of a channel-shaped strip, for example, which grips onto a flange surrounding the vehicle opening. In use, the door, window or lid for the opening closes onto the soft tubular seal with the aim of providing a draught or weather excluding seal.
Various novel features of the invention will be apparent from the following description, given by way of example only, of a seal embodying the invention, a system embodying the invention and incorporating such a seal, and a vehicle including such a system, reference being made to the accompanying diagrammatic drawings in which: Figure 1 is d perspective view of the seal; Figure 2 is a section showing the seal mounted on a vehicle body flange; and Figure 3 is a perspective and diagrammatic view of a motor vehicle showing the seal mounted thereon.
More specifically to be described below is a sealing strip for mounting around an opening on a vehicle body which has a closable member for closing the opening, the seal being in the form of a flexible hollow member which is arranged to be partially flattened by the closure member when it closes the opening, and means for increasing the air pressure within the hollow member.
Advantageously, the means for increasing the air pressure within the hollow member comprises a tube connected to the interior of the hollow member and means for forcing air into the tube.
Advantageously, the means for forcing air into the tube comprises means for mounting the tube on the vehicle on which the hollow member is fitted, the distal end of the tube being located on the front of the vehicle so as to be open to the air adjacent the frontal area of the vehicle.
In a more specific sense, there will be described a system for sealing openings on a vehicle body, comprising a sealing strip mounted on the vehicle body around the opening and including a hollow tubular seal made of flexible material and extending at least partially around the opening and onto which a closure member for the opening closes, and a tube having one of its ends in communication with the interior of the tubular seal and the other end mounted at the front of the vehicle and open to the atmosphere adjacent the frontal area of the vehicle so that motion of the vehicle forces air into the tube to increase the air pressure within the tubular seal.
Advantageously, the sealing strip includes a channel-shaped strip on the outside of which is mounted the tubular seal, the channel-shaped strip being mounted on a flange surrounding the vehicle opening so as to hold the tubular seal in position.
As shown in Figures 1 and 2, the strip comprises a gripping portion 5 and a sealing portion 6. The gripping portion 5 is channelshaped and is made of plastics material 8 in which is embedded a core or carrier 10, made of metal for example. The carrier 10 may comprise a series of side-by-side U-shaped elements which are flexibly connected together by short connecting links, or are completely unconnected. Instead, for example, the carrier 10 may be made of wire.
Other forms are possible. In whatever form, the carrier 10 is arranged to be longitudinally flexible.
The plastics material 8 may be formed onto the carrier 10 by means of an extrusion process.
Preferably, the plastics material is formed with integral gripping ribs 12, 14.
The sealing section is a generally tubular seal 16 which may be made of rubber or plastics material, preferably sponge rubber material, and is attached to the outside of one wall of the gripping section 5. The seal 1 6 may be attached to the gripping section 5 by means of adhesive. Instead, however, it may be formed integrally with the flexible material 8 as by a dual extrusion process.
Figure 2 shows how the strip is mounted in position on a flange 1 8 running around an opening on a motor vehicle body, such as a door opening.
As shown, the gripping section 5 grips the flange 18, the gripping ribs 12, 14 performing a gripping and sealing function. As so mounted, the strip presents the seal 1 6 towards the door, and window carried by the door, around all or most of the opening so that when the door is closed onto the opening, it and its window make contact with the seal 1 6 and partially compress it with a view to forming a draught and weather excluding seal.
Figure 2 shows the window 20 pressing against the seal 16.
As shown in Figure 1, a small hollow tube 22 connects with the interior of the tubular seal 1 6 at a point along its length. As shown in Figure 3, this tube 22 is led from the strip, within the body of the vehicle, to an area at the front of the vehicle where it connects with an open ended, enlarged mouth portion 24. As shown in Figure 3, a preferred position for this is adjacent the spoiler 26 on the front of the vehicle.
In use, motion of the vehicle causes air to be forced into the tube 22 through the enlarged mouth portion 24, thus raising the air pressure in the tube 22, and thus in the seal 16 which is closed off from the atmosphere except for the tube 22. The effect of this is to tend to expand the tubular seal 1 6 and to press it into tighter contact with the window 20. This therefore increases the draught and weather excluding sealing action between the seal 1 5 and the window 20. This is particularly advantageous as the vehicle speed increases because it is at higher vehicle speeds that the passage of the vehicle through the air tends to cause a slight lowering of ambient atmospheric pressure externally of the vehicle.The pressure inside the vehicle therefore tends to force the window 20 outwardly and to reduce the effectiveness of the sealing action provided by the seal 1 6. The increased air pressure within the seal 1 6, provided by the increased pressure in the tube 22, thus compensates for this.
It will be appreciated that further tubes corresponding to the tube 22 may be led from the front of the vehicle to the tubular seals (corresponding to the seal 16) around other openings on the vehicle. More than one tube 22 may feed the seal around one opening, particularly where the seal is in separated parts.
The effectiveness of the arrangement is enhanced by the fact that the increased pressure in the tube 18 will tend to increase as the square of the vehicle speed.
Although the description above refers to the improved sealing effect produced against a vehicle window, it will be appreciated that in similar fashion an improved sealing effect may be produced against the vehicle door or other closure member such as the lid for the engine or luggage compartments or the sliding roof.

Claims (8)
