Abstract

A door seal structure for sealing between a door opening portion of a vehicle body and a door frame of a vehicle door. The door seal structure has a protrusion formed in the door frame and protruding inwardly of a glass run holding part for holding a glass run, and a cover member for covering the protrusion and concealing it from a vehicle compartment when the vehicle door is closed. The protrusion has a longitudinally extending depression near a protruding wall of the protrusion, and an inner end edge of the cover member is seated in the longitudinally extending depression. When the vehicle door is closed, the protrusion of the door frame is not seen from the vehicle compartment, and the inner end edge of the cover member does not contact a tubular seal portion of an opening weather strip attached along the door opening portion to prevent wear of the tubular seal portion. Accordingly, the appearance and durability around the door frame are improved.

Claims

1. A door seal structure for sealing between a door opening portion of a vehicle body and a door frame of a vehicle door, comprising:

an opening weather strip provided in the door opening portion, said opening weather strip including a tubular seal portion which projects outwardly of the door opening portion;

a glass run for guiding a door glass that is raised or lowered, said glass run being held in a glass run holding part provided along an inner peripheral surface of the door frame;

the door frame having a protrusion which protrudes inwardly of said glass run holding part, said protrusion including a protruding wall and an inside wall, said protruding wall being adapted to contact and press said tubular seal portion of said opening weather strip and said inside wall being adapted to face a vehicle compartment when the vehicle door is closed, said inside wall of said protrusion having a depression which is formed near said protruding wall so as to extend in a longitudinal direction of said protrusion; and

a cover member provided for covering said inside wall of said protrusion of the door frame, one end edge of said cover member being connected to said glass run and the other end edge of said cover member being seated in said depression.

4. A door seal structure as claimed in claim 1, wherein said cover member includes a trim part which is integrally formed with one part of said inner side wall of said glass run, and a cover lip which extends inwardly from said trim part integrally with said trim part, said trim part of said cover member is connected to said glass run, and an end edge of said cover lip is seated in said depression.

8. A door seal structure as claimed in claim 1, wherein said cover member is composed of a door frame garnish which is formed separately from said glass run, and one end edge of said door frame garnish abuts and is connected to an inner side wall of said glass run, and the other end edge of said door frame garnish is seated in said depression.

13. A door seal structure as claimed in claim 8, wherein said protrusion has a first depression near said inner side wall of said glass run and a second depression near said protruding wall, said one end edge of said door frame garnish is seated in said first depression, and abuts and is connected to said inner side wall of said glass run, said the other end edge of said door frame garnish is seated in said second depression, and said door frame garnish is secured to said protrusion by a double-sided adhesive tape.

2. A door seal structure for sealing between a door opening portion of a vehicle body and a door frame of a vehicle door, comprising:

an opening weather strip provided in the door opening portion, said opening weather strip including a tubular seal portion which projects outwardly of the door opening portion;

a glass run for guiding a door glass that is raised or lowered, said glass run being held in a glass run holding part provided along an inner peripheral surface of the door frame;

the door frame having a protrusion which protrudes inwardly of said glass run holding part, an inner peripheral end of said protrusion being joined to an inner side wall of said glass run holding part to define a flange, said protrusion including a protruding wall and an inside wall, said protruding wall being adapted to contact and press said tubular seal portion of said opening weather strip and said inside wall being adapted to face a vehicle compartment when the vehicle door is closed, said inside wall of said protrusion having a depression which is formed near said protruding wall so as to extend in a longitudinal direction of said protrusion; and

a cover member provided for covering said inside wall of said protrusion of the door frame, one end edge of said cover member covering said flange and being connected to said glass run and the other end edge of said cover member being seated in said depression.

5. A door seal structure as claimed in claim 2, wherein said cover member includes a trim part which is integrally formed with one part of an inner side wall of said glass run, and a cover lip which extends inwardly from said trim part integrally with said trim part, said trim part of said cover member is connected to said glass run, and an end edge of said cover lip is seated in said depression.

7. A door seal structure as claimed in claim 5, wherein said trim part is mounted on said flange, and an outer side wall of said trim part abuts and is connected to said inner side wall of said glass run.

9. A door seal structure as claimed in claim 2, wherein said cover member is composed of a door frame garnish which is formed separately from said glass run, and one end edge of said door frame garnish abuts and is connected to an inner side wall of said glass run, and the other end edge of said door frame garnish is seated in said depression.

11. A door seal structure as claimed in claim 9, wherein said one end edge of said door frame garnish has a flange mounting part for mounting on said flange.

3. A door seal structure for sealing between a door opening portion of a vehicle body and a door frame of a vehicle door, comprising:

an opening weather strip provided in the door opening portion, said opening weather strip including a tubular seal portion which projects outwardly of the door opening portion;

a glass run for guiding a door glass that is raised or lowered, said glass run being held in a glass run holding part provided along an inner peripheral surface of the door frame;

a door weather strip for abutting and sealing the door opening portion when the vehicle door is closed, said door weather strip being held in an outer peripheral surface of the door frame;

the door frame having a protrusion which protrudes inwardly of said glass run holding part, said protrusion including a protruding wall and an inside wall, said protruding wall being adapted to contact and press said tubular seal portion of said opening weather strip and said inside wall being adapted to face a vehicle compartment when the vehicle door is closed, said inside wall of said protrusion having a depression which is formed near said protruding wall so as to extend in a longitudinal direction of said protrusion; and

a cover member provided for covering said inside wall of said protrusion of the door frame, one end edge of said cover member being connected to said glass run and the other end edge of said cover member being seated in said depression.

6. A door seal structure as claimed in claim 3, wherein said cover member includes a trim part which is integrally formed with one part of an inner side wall of said glass run, and a cover lip which extends inwardly from said trim part integrally with said trim part, said trim part of said cover member is connected to said inner side wall of said glass run, and an end edge of said cover lip is accommodated in said depression.

10. A door seal structure as claimed in claim 3, wherein said cover member is composed of a door frame garnish which is formed separately from said glass run, and one end edge of said door frame garnish abuts and is connected to an inner side wall of said glass run, and the other end edge of said door frame garnish is seated in said depression.
