Definitions

  • the invention relates to a sealing element for sealing off component groups capable of being positioned in relation to one another, in particular for use in the vehicle and building technology sector, the sealing element including a first seal part performing a sealing function and a second seal part.
  • sealing elements are known from the prior art.
  • sealing elements which consist only of a soft material, and in the case of an open profile configuration which can be produced without further additional measures, tend under loads, especially transverse to the seal position, to experience distortions of the profile of the sealing element, thus leading to a leak and possibly to operational failure.
  • sealing elements having a compound construction are also known from the prior art.
  • DE 696 04 094 T2 discloses a sealing profile and a method for producing it, said sealing profile being produced by means of extrusion and having a reinforcement composed of thermoplastic and also a coating composed of elastomer, the reinforcement consisting of fiber-filled thermoplastic and being completely covered by at least one film or thin layer of non-fiber-filled thermoplastic to which the coating composed of elastomer adheres.
  • the object on which the invention is based is, while preserving the advantages existing hitherto, to improve or develop further the known sealing elements to the effect that a sealing-off construction is made available, in which the sealing function is afforded in full and in which there is stabilization against deformation loads which may lead to functional restrictions or to operational failure.
  • a cost-effective and visually pleasing design capable of being produced simply in a reproducible quality is at the same time to be implemented.
  • a sealing element is of an essentially annular design and has an essentially arcuately designed first seal part directed inward in the operating position, with a soft fraction, and an essentially frame-shaped second seal part arranged at the inwardly projecting end of the first seal part, with a hard fraction.
  • the load acting transversely to the sealing direction is in this case absorbed by the essentially frame-shaped second seal part with a hard fraction, in such a way that a regional distortion of the sealing element can no longer take place, a sealing deformation of the soft fraction in the sealing direction continuing to be present in a functionally appropriate way, and, moreover, a uniform sealing bearing contact being assisted by this construction, since a regional profile collapse is prevented by the supporting action of the frame-shaped seal part with a hard fraction.
  • the sealing element according to the invention can have a visually pleasing design and affords increased freedom of configuration.
  • the second seal part with a hard fraction is designed as a peripheral reinforcement. This design is especially advantageous in structural terms.
  • the second seal part with a hard fraction is designed as a part element integrally formed by injection molding. This design is advantageous in manufacturing terms.
  • the essentially annularly designed sealing element be designed as a closed ring. This is an embodiment which is advantageous for achieving good sealing off.
  • the essentially frame-shaped second seal part of the sealing element is not arranged in direct range of vision. In this case, there is no need for the provision of additional visually effective means for improving the external appearance.
  • the essentially frame-shaped second seal part of the sealing element is arranged in direct range of vision.
  • the essentially frame-shaped second seal part of the sealing element be designed with the same color as the first seal part.
  • this essentially frame-shaped second seal part of the sealing element has an injection overmolding.
  • FIG. 1 shows a vertical section through the sealing element according to the invention for an air outlet seal of a door trim on the B-column of a vehicle.
  • a sealing element 10 serves for sealing off component groups capable of being positioned in relation to one another, in particular for use in the vehicle and building technology sector.
  • the sealing element 10 comprises a first seal part, designated by 11 , performing a sealing function and having a soft fraction and a second seal part, designated by 12 , performing a reinforcing function and having a hard fraction.
  • FIG. 1 of the drawing illustrates the sealing element 10 according to the invention with the first seal part 11 and with the second seal part 12 , the sealing element 10 being used here between two component groups merely indicated and not designated.
  • broken lines illustrate a profile distortion, designated by 14 , of the first seal part 11 , with a soft fraction, of a sealing element 10 , as is known from the prior art.
  • the sealing element 10 is of essentially annular design, and it has an essentially arcuately designed first seal part 11 directed inward in the operating position, with a soft fraction, and an essentially frame-shaped second seal part 12 arranged at the inwardly projecting end of the first seal part 11 , with a hard fraction.
  • the second seal part 12 with a hard fraction is designed as a peripheral reinforcement 13 .
  • This second seal part 12 with a hard fraction may in this case preferably be designed as a part element integrally formed by injection molding.
  • the essentially annularly designed sealing element 10 is designed as a closed ring.
  • this closed ring is provided, for example, for use on an air outlet seal of a door trim on the B-column of a vehicle.
  • the air from the instrument panel region can be conducted into the door and, via an air duct, into the B-column and from there into the back space.
  • the transitions of the components are to be sealed off against the outlet of air, and roses with seals can be used in the door trim.
  • the closing direction of the doors is transverse to the seal routing.
  • the solution possibility illustrated is a seal which is produced in one part in a process sequence as a 2-component injection molding with a soft fraction for the seal itself and with a peripheral frame-shaped hard fraction which is firmly tied to the open geometrical end of the soft fraction.
  • the sealing element 10 according to the invention can be used between two component groups, and, during the assembly of the component groups, even a load acting transversely to the seal position, see the arrow A in FIG. 1 , can be compensated; in the sealing element 10 according to the invention, this takes place in that the hard fraction of the second seal part 12 stabilizes the geometry of the soft fraction of the first seal part 11 and acting transverse forces can be absorbed, with the result that possible profile distortion is prevented.
  • the sealing function itself in this case continues to take place by means of sealing bearing contact via the soft fraction.
  • the load according to the arrow A which acts transversely to the sealing direction is absorbed in such a way that a regional distortion of the sealing element 10 can no longer take place, a sealing deformation of the soft fraction in the sealing direction continuing to be present in a functionally appropriate way, and, moreover, uniform sealing bearing contact being assisted by this construction, since a regional profile collapse is prevented by the supporting action of the frame-shaped seal part 12 with a hard fraction.
  • the sealing element 10 according to the invention can have visually pleasing design and affords increased freedom of configuration.
  • the essentially frame-shaped second seal part 12 of the sealing element 10 cannot be arranged in direct range of vision.
  • the essentially frame-shaped second seal part 12 of the sealing element 10 may be arranged in direct range of vision.
  • the essentially frame-shaped second seal part 12 in particular together with the first seal part 11 , may have an injection overmolding, not designated in any more detail here. In this case, however, a somewhat increased outlay in die terms is required during manufacture.
  • the essentially frame-shaped second seal part 12 of the sealing element 10 is designed with the same color as the first seal part 11 .
  • the sealing element 10 according to the invention can be used for all seals, such as, for example, air routing seals with a support requirement, for example on vehicle parts.
  • the sealing element 10 according to the invention can be used for all seals, such as, for example, air routing seals with a support requirement, for example on vehicle parts.
