Abstract

This door joint comprises a fixing element (1) covering a projecting part (2) of a door-frame (3) and two tubular elements (6 and 8) made of a material deformed in an elastic manner, whereby one tubular element (6) adjoins the other tubular element (8) and said fixing element (1), said tubular elements (6 and 8) are to be interposed between door-frame (3) and associated door (7) in its closed position in order to ensure the tightness of the assembly.

According to the invention, the two tubular elements (6 and 8) communicate through at least one orifice (9) or through a continuous passage, whereby the compression of one of the tubular elements (6) between the door and the door-frame results in the deformation of said latter element and in an inflation of the second tubular element (8) between said door and said door-frame.

Claims

1. A door joint for automobile doors comprising a fixing element covering a projecting part of a door-frame and first and second tubular elements made of an elastically deformable material the first tubular element adjoining the second tubular element and said fixing element, said tubular elements adapted to be interposed between said door frame and an associated door in its closed position in order to ensure the tightness of the assembly, said door joint further comprising a communicating section between said first and second tubular elements configured at least as one orifice or a continuous passage so that the compression of the first tubular element between the door and the door-frame results in said first tubular element'"'"'s deformation and in an inflation of the second tubular element between said door and said door-frame.

2. A door joint for automobile doors comprising a fixing element covering a projecting part of a door-frame and first and second tubular elements made of an elastically deformable material, the first tubular element adjoining the second tubular element and said fixing element, said tubular elements adapted to be interposed between said door frame and an associated door in its closed position in order to ensure the tightness of the assembly, said door joint further comprising a communicating section between said first and second tubular elements configured at least as one orifice or a continuous passage so that the compression of the first tubular element between the door and the door-frame results in said first tubular element'"'"'s deformation and in an inflation of the second tubular element between said door and said door-frame, the first tubular element arranged in such a manner that it may be deformed by the door and compressed by an edge of the door while the second tubular element is interposed between an inside surface of the door and the door-frame.

3. The door joint according to claim 2, in which the dimensions of the second tubular element are such that said second tubular element is not directly affected by the door while it is closed, said second tubular element contacting the door only when said second tubular element expands due to the pressure of the air forced out from the first tubular element when the first tubular element is compressed.
