Definitions

  • the invention relates to a sealing profile for a sliding window pane of a motor vehicle, a sealing arrangement for a displaceable window pane of a motor vehicle and a motor vehicle door with a sealing arrangement according to the invention.
  • Sliding window panes can be found today in all types of motor vehicles. Either with the aid of purely mechanical or electrical aids, a movable window pane is movable in a guide frame of a motor vehicle door. There are various requirements for the storage of the window pane in its guide frame. This relates to a smooth mobility when moving the window in the form of opening and closing the window. On the other hand, however, this also applies to a good sound, heat and moisture insulation between the vehicle interior and the external vehicle environment. In a third aspect, windows require a so-called good "acoustic performance.” This means that a disc must be supported against vibration in order to prevent vibration of the vehicle resulting in rattling noises of the window pane.
  • DE 103 13 601 A1 discloses a sealing arrangement for sealing and guiding a movable window pane, wherein the sealing base is formed by a hollow chamber.
  • the US 630 18 34 discloses a holder for a window, which is arranged movably in a provided with sealing lips guide rail.
  • the sealing base of the guide rail is pressed by springs elastically to the holder.
  • WO 97/25218 describes a sealing lip arrangement for a window pane, wherein a fold is provided as the sealing base, which has a cavity.
  • DE 103 02 429 A1 discloses a power window assembly for a motor vehicle with a sliding window, in which case a stop of an elastic material is provided as a sealing base.
  • US 6 286 841 B1 describes a seal for a movable window pane, the sealing base being reinforced by a material, such as metal.
  • JP 08318740 A discloses a sealing profile for a window pane of a motor vehicle, wherein a cavity is formed in the sealing base, in which project rib-shaped elements.
  • the invention is the object of the invention to provide an improved sealing profile for a sliding window pane of a motor vehicle, an improved sealing arrangement for a sliding window pane of a motor vehicle and an improved motor vehicle door with a sealing arrangement.
  • a sealing profile for a displaceable window pane of a motor vehicle, wherein the sealing profile has a base and two legs, wherein the two legs are designed to resiliently enclose two opposite side surfaces of the window pane.
  • the base has a contact surface with the end face of the window pane for guiding the end face of the window pane in the longitudinal direction of the sealing profile.
  • the cavity has means for ventilation.
  • at least one Strengthening rib arranged, wherein the reinforcing rib extends substantially in the longitudinal direction of the sealing profile, wherein the reinforcing rib extends in the cavity.
  • the means for ventilation are designed so that a quantity of air contained in the cavity acts as a spring element. This is an optimal vibration damped mounting of the window in the sealing profile given.
  • the sealing profile according to the invention also has the advantage that a moving window pane, in particular due to the movement of the disc corner over the base of the sealing profile, does not deform the base. It should be noted here that commonly the base is also referred to as a "seal bottom".
  • any type of deformation of the sealing lip causes the smooth running of a window pane to be impaired by a deformation of the sealing basis, i. significantly degrades the base, which may result in damage to the mechanical components used to move the window, as well as the window itself.
  • the sealing profile according to the present invention combines both the acoustic comfort of a seal with a sealing lip in the base and the mechanical requirements with regard to the stability with regard to deformability of the sealing base.
  • the reinforcing rib contributes significantly to the fact that a corrugation of the base is avoided by a moving along front side of a window pane.
  • the linear seal ground on the back is stiffened by the ribbing, thus increasing the flexural rigidity of the linear guide member. This increases the bending stiffness of the linear guide element about the y-axis and thus effectively prevents a "dipping" of the disc in the seal and thus the sliding of the seal, so that situations with increased friction losses can be avoided.
  • the reinforcing rib further comprises a stiffening insert.
  • a stiffening insert may for example be a material with a higher hardness (EPDM or TPE), a metal insert or a plastic insert. This stiffening insert now leads to a further increase in the bending stiffness of the base, so that a bulging of the sealing base is almost completely avoided.
  • the base and / or the legs and / or the reinforcing rib are formed integrally with each other.
  • the cavity has an elastic foam see filling.
  • an open-pored foam is used.
  • the cavity is only filled with air, wherein generally the means for ventilation and play an important role:
  • the same applies to the opening of a window pane in which case removal of the front side of the window pane from the base of the pane relieves the load on the cavity so that it again tries to expand due to its elastic configuration.
  • the means for ventilating the cavity now have the task of supplying the cavity with the necessary air.
  • the sealing profile on at least two of the reinforcing ribs wherein the two reinforcing ribs are each arranged laterally from the contact surface of the base.
  • Such an arrangement of at least two of the reinforcing ribs has the advantage that an additional guiding function of the window pane in the sealing profile in the transverse direction to the sealing profile is provided.
  • a friction-reducing layer is arranged on the contact surface.
  • the elastically deformable cavity for vibration damping of the window pane is formed.
  • the cavity is formed in the base itself.
  • the base encloses the cavity and has for the ventilation of the cavity corresponding means.
  • the sealing profile is provided for receiving by a guide frame, wherein the cavity is formed by the base and the guide frame itself.
  • the cavity tapers in the direction of a longitudinal end of the sealing profile towards the bottom.
  • a tapering of the cavity has the advantage that the shape of the sealing profile thus expiring at this end facilitates retraction and extension of the disc into the sealing profile itself.
  • the invention relates to a sealing arrangement for a sliding window pane of a motor vehicle with a sealing profile, wherein the guide frame has at least one longitudinal shape for receiving the at least one reinforcing rib, wherein the reinforcing rib by a force on the contact surface in the molding is einpressbar.
