Definitions

  • the invention relates to a sealing strip according to the preamble of claim 1.
  • Sealing strips which are composed of the juxtaposition of a hollow profile or hose-like sealing portion and a U-shaped, for mounting on a peripheral web, for example, a door frame of a motor vehicle certain attachment portion are known as such in the home of the applicant.
  • the attachment portion is designed primarily with a view to a reliable seat directed against unintentional release from the web, whereas the weatherstrip often has to perform damping functions by providing a buffer zone between relatively metallic components, e.g. a door surround and a door surround forms.
  • the sealing portion In the closed state of the door, the sealing portion is elastically deformed and it should be made of material and its shape with the proviso that a stable over time recovery capacity is given, and that within the usual, resulting from the operation of the vehicle temperatures.
  • the hollow profile of the sealing portion is regularly provided with vents, which are provided in accordance with a uniform distribution along the extent thereof.
  • vents are regular adverse effects on the mechanical stability of the cross-sectional profile of the sealing portion. This affects in particular when laying the sealing strip along small radii of curvature such. in the range of door corners and the like and can lead to a complete collapse of the cross-sectional profile in the limit.
  • a locally collapsed seal section can fulfill its sealing and damping function only very imperfectly.
  • vents in a visible in the installed state of the sealing strip area.
  • the disadvantage here is that in this way not only an intrusion of dirt in the structure of the sealing portion is facilitated.
  • circular vents are always deformed more or less oval in accordance with the curvatures along which they are laid in the installed state, and in extreme cases can be extremely distorted in accordance with the respective radius of curvature.
  • This circumstance not only leads to a very unfavorable external appearance of the sealing strip - in accordance with the local distortion caused by a non-uniform voltage distribution, an excessive mechanical stress is also locally given, which reduces the service life of this component.
  • the cross-sectional profile of the sealing portion is partially formed by the one facing leg of the fastening portion.
  • the latter completes with other cross-section sections the complete hollow profile of the sealing section.
  • the flexural rigidity also greatly stiffening the seal portion, which significantly contributes to collapse the cross-sectional profile of the sealing portion to prevent even when laying along small radii of curvature.
  • the part of the cross-sectional profile of the sealing portion, which faces the said leg of the fastening portion, is in a fixed connection with the latter along its entire contact surface.
  • the vents are located on the, the underside of the sealing strip facing side and in a region of greatest wall thickness of the cross-sectional profile of the sealing portion.
  • an otherwise given weakening influence of the vents is reduced to a minimum.
  • Another advantage is that - seen in the installed state - the vents are located on the bottom, thus on a visually invisible and not the entire appearance of the assembled weather strip non-affecting point. The vents could thus fulfill their function, without any of these adversely affecting the function of the sealing strip.
  • the features of claim 2 have the advantage that the Wandungsdickenverlauf the sealing portion is constructively adjustable with the proviso that a sufficient elastic deformability is given and at the same time emanating from the vents not the stability of the cross-sectional profile of the sealing portion impairing influence.
  • the features of claim 3 bring on the one hand the advantage that the design stability of the sealing portion is improved by design, thus without a much higher material use by a U-shaped recess is formed on the underside of the sealing strip, which on the one hand a formed on the sealing portion rib and on the other hand by the, the sealing portion facing leg of the mounting portion is formed. With regard to a bend around an axis located in a cross-sectional plane of the sealing portion, this design has the effect of increasing stability. Further, by the vent openings are arranged in the profile base of this recess, they are arranged in any case at a visually hardly or not at all visible place. It is thus a further measure to impart an advantageous appearance of the sealing strip in the installed state.
  • a bar is integrally formed on the attachment portion and that at its side opposite the sealing portion, which circumscribes together with the facing leg of the attachment portion of a cavity open to the underside of the sealing strip.
  • This bar mainly fulfills the function of a
  • Screen and it may be covered on the outside with a textile cover or be decorative treated in any other way.
  • claims 5 and 6 are directed to the material configuration of the attachment portion and the bar. Both may hereinafter be made of, for example, a soft rubber.
  • the U-shaped structure of the fastening portion is provided with a preferably metallic reinforcement.
  • This reinforcement first of all, in a manner known per se, increases the strength of the U-shaped structure of the fastening section and allows a comparatively thin-walled construction.
  • a suitable reinforcement in particular a corresponding design is beyond the possibility of elastic restoring forces of the fastener structurally provided for a stable seat on a web on soft the mounting bar is plugged.
  • the reinforcement assumes a stabilizing influence on the cross-sectional profile of the fastening section, even under the generally expected spatial curvatures along which the boundaries of vehicle openings run.
  • the arrangement of a metallic reinforcement is generally preferred - but an existing from a suitable plastic, having a high elastic recovery Ar- ming is not excluded.
  • the sealing portion is at least partially made of sponge rubber.
  • the sealing portion may consist of a hose-like hollow profile which is in fixed connection along a part of its circumference with the facing side of the fastening portion. In this way, the stability and the rigidity of the cross-sectional profile of the sealing portion determining influence of the fastening portion is secured.
  • the existing, made of soft rubber facing legs of the mounting portion directly form a wall portion of the hollow profile of the sealing portion, so that only remaining remaining wall sections are made of sponge rubber.
  • the outer or visible region of the sealing section may be coated with anti-friction varnish or a coating of essentially the same effect.
  • This measure essentially serves to reduce wear, after it is in each closing and opening operation of the door relative movements between the surface of the sealing portion, which is, for example, with the enclosure of a door opening in a fixed connection and the opposite metallic structures of the door comes.
  • This profile consists of the juxtaposition of a hollow profile-like sealing portion 1, a U-shaped mounting portion 2 and a, on the latter laterally molded, mainly a screen forming bar.
  • the attachment portion 2 is equipped with a likewise U-shaped metal reinforcement 4 and intended for attachment to a drawing, not shown, mounted on the edge of the opening of a motor vehicle web.
  • the fastening portion 2 is provided on its inside with spring tongues 5, 6, starting from the right-hand leg 2 'at a distance approximately parallel to each other and - with respect to the U-profile of the mounting portion 2 - inwardly In the direction of the profiled ground 2 ", on the inner side of the fastening profile 2 there is a sawtooth-like profiling 7, which lies opposite the spring tongues 5, 6 and which consists of a sequence of flank sections which rise flat in the direction of the profiled ground 2 ' T, to which each steeply sloping comparatively short edge portions 7 "join.
  • the holding effect exerted by the spring tongues 5, 6 in connection with the profiling 7, which is exerted on the aforementioned web, is reinforced by an elastic restoring force of the reinforcement 4, so that overall a reliable seat of the sealing strip is provided.
  • an elastic restoring force of the reinforcement 4 due to the orientation of the spring tongues 5, 6 and the profiling 7 relative to the profile base 2 "unintentional release of the sealing strip of the web prevented reliably.
  • Formed on the side of the leg 2 1 of the attachment portion 2 is said strip 3, which has a curved towards the lower end 8 of the right leg curve course.
  • the strip 3 thus defines, together with the leg 2 1, a cavity 9 "which is open toward the underside 1 'of the sealing strip.
  • the wall of the sealing section 1 is formed on the side facing the fastening section 2 directly by its leg 2 '"on the left in the drawing, which has on its outside a groove 14 extending approximately parallel to the leg A solid seat of the laminating tape is otherwise secured by a spring tongue 15, which is integrally formed on the entrance of the groove 14 and protrudes into this, so that it is elastically deflected in the assembled state of the laminating belt 12 ,
  • Essential feature of the remaining wall of the hollow profile of the sealing portion 1 is a wall thickness, which at its lower, ie the free end 16 of the leg 2 "'of the mounting portion 2 facing part significantly larger fails in such, the bottom 1' facing, in the direction on the leg 2 '"towards upward with respect to the bottom 1 1 extending wall portion 17 are - as seen in accordance with uniform distances in the longitudinal direction of the sealing strip - vents, regularly vent holes 18th
  • vent holes 18 in the assembled state of the sealing strip are in any case not in a visible area. It can be seen further that these vent holes 17 are located in such wall sections, which are reinforced in relation to other wall sections with respect to their wall thickness, so that even in the case of laying the sealing strip in accordance with strong bends not with a collapse of the hollow section of the Sealing part 1 is expected.
  • the Wandungsdickenverlauf starting from the Wandungsabites 17 is by a, approximately parallel to the leg 2 '"extending central portion 17' and another, the hollow profile of the sealing portion 1 in the direction of the leg 2" towards completing, relative to the middle section 17 'thinner walled portion 17 "marked.
  • the wall section 17 extends upwards from its connecting region with the middle section 17 'at an angle to the leg 2 "."
  • the fact that the vent hole 18 is thus at the bottom 19' of the recess 19 also contributes to the fact that it hardly is perceptible.
  • the attachment section 2 and the strip 3 can be made of a soft rubber, whereas the majority of the seal section 1 consisting of the section 17 ", the middle section 1 T and the wall section 17 consists of a sponge rubber Both materials and the reinforcement 4 can be prepared by coextrusion in a continuous process.
  • the outer portion 20 of the sealing portion is coated in the usual manner with a bonded coating.
  • denoted by 23 is a thread which is integrated into the substance of the fastening part.

Abstract

L'invention concerne une baguette d'étanchéité destinée à être placée sur l'arête du bord de l'ouverture d'un véhicule. Cette baguette d'étanchéité est constituée de la juxtaposition d'une section d'étanchéité (1) tubulaire, d'une section de fixation (2) en U et d'une baguette (3) formée latéralement sur la section de fixation (2), ladite baguette (3) délimitant avec une branche (2') de la section de fixation (2) une cavité (9'') ouverte sur le côté inférieur (1') de la baguette d'étanchéité. Le profil transversal de la section d'étanchéité (1) est formé partiellement par la branche (2''') de la section de fixation (2) adjacente à ladite section d'étanchéité (1), des trous d'aération (18) étant situés sur le côté inférieur de la baguette d'étanchéité adjacent au bord susmentionné et formant une zone de la section d'étanchéité (1) présentant la plus grande épaisseur de paroi. Cette disposition de l'ouverture d'aération présente l'avantage que ladite ouverture n'entraîne sensiblement aucun effet négatif sur la rigidité flexionnelle du profil transversal de sorte que la baguette d'étanchéité peut être posée également le long de rayons de courbure inférieurs sans risque d'affaissement du profil. Les ouvertures d'aération étant placées sur un côté inférieur adjacent au bord, l'aspect optique n'est pas non plus affecté.
