Abstract

PROBLEM TO BE SOLVED: To provide a door weather strip capable of preventing passing water even if it receives high pressure water when washing a vehicle and being assem bled easily. SOLUTION: In this door weather strip 1 in which a basic bottom part 2 is fitted into a fitting part 9 of a sash 8 at a door peripheral fringe D, a recessed part 4 engaging a protruding part 10 rising at the door end fringe D is formed between a back face lip 3 above a protruding fringe 2a on the outside of the vehicle of the basic bottom part 2 and it, and a soft member 5 such as a high foaming sponge is provided in a bottom part of the recessed part 4 so that the protruding part 10 adheres closely to the soft member 5 in the recessed part 4 when mounting the door weather strip 1.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door weather strip.

[0002]

2. Description of the Related Art As shown in FIG. 2, a conventional door weatherstrip is generally fitted with a base portion 2 of a door weatherstrip 11 fitted into a fitting portion 9 of a sash 8 on a peripheral edge D of an automobile door. When the door is closed, the sub-seal lip 6 above the base 2 elastically contacts the vehicle body opening 12 to provide waterproofing against rainwater and the like.

[0003]

However, there is a problem that the sub-seal lip 6 is pressed by high-pressure water at the time of car washing and the like, and the lower rear lip 3 separates from the door edge D to generate water therethrough. Was. As a countermeasure, if the rear lip 3 is extended and strongly brought into close contact with the door edge D as shown in FIG. 3, the door weather strip 11 rolls as shown by the arrow when the assembly is not properly performed on the sash 8 due to the pressing force. However, the desired seal form was not obtained. Also, the base 2
If the recess 4 above the outer protrusion 2a and the protrusion 10 of the door edge D are tightly engaged, there is a problem that the workability of assembling the sash 8 is deteriorated. In view of the above, it is an object of the present invention to provide a door weather strip which can prevent passing water even when receiving high-pressure water at the time of car washing or the like and can be easily assembled.

[0004]

In order to achieve the above object, the structure of the present invention is, as shown in FIG.
In the door weather strip 1 in which the base portion 2 is fitted to the fitting portion 9 of the sash 8 of the sash 8, a bulge is formed on the door edge D between the base portion 2 and the rear lip 3 above the vehicle-side protruding edge 2 a. A concave member 4 is formed to engage with the formed projection 10. A soft member 5 such as a highly foamed sponge is attached to the bottom of the concave 4, and the soft member 5 of the concave 4 is attached to the soft member 5 of the concave 4 when the door weather strip 1 is attached. 10 is brought into close contact.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. In FIG. 1, reference numeral 1 denotes a door weather strip, and a recess 4 is formed between a base portion 2 and a rear lip 3 above a vehicle-side protruding edge 2a. A soft member 5 made of a highly foamed sponge is integrally provided at the bottom of the concave portion 4 at the time of extrusion molding. The high foaming sponge has a specific gravity of 0.1
, And a normal sponge constituting another portion has a specific gravity of 0.45 to 0.65. 6 is a sub-seal lip, and 7 is a hollow seal part.

When the door weather strip 1 is mounted, the outer side projection 2a and the inner side projection 2b are fitted into the fitting portion 9 having the engagement concave grooves 9a, 9b on both sides of the sash 8 on the door peripheral edge D.
Is pushed in and fitted. At this time, the protrusion 10 protruding inside the door edge D is engaged with the concave portion 4 and bites into the soft member 5 as shown by the dotted line, thereby making a close contact. As described above, since the protrusion 10 is closely contacted with the soft member 5 of the recess 4, even if high-pressure water is flooded in the gap between the door peripheral edge D and the back lip 3, unlike the conventional case, the flooding path into the room is reliably blocked. Is done.

[0007]

When the door weather strip of the present invention is attached to a door, the protrusion at the door edge is strongly applied to a soft member such as a high-foam sponge provided in a concave portion above the outer edge of the vehicle at the base. Because of the close contact, there is the advantage that unlike the conventional case, the infiltration of the vehicle interior by high-pressure water is reliably prevented, the rolling is prevented, and the assembling workability is not impaired.
