Weather strip for motor vehicle

Abstract

A weather strip for a motor vehicle, which is capable of being elongated or contracted upon the attachment to a vehicle body, thereby facilitating the attachment thereof. The weather strip has a ring-shaped configuration by connecting longitudinal ends thereof to each other with a connecting section, and includes a base portion for attachment to a flange provided in a closing member for closing an opening in a vehicle body or an opening portion around the opening, and a seal portion integrally formed with the base portion for contacting a facing member, that is the opening portion or the closing member and sealing a gap therebetween. The base portion includes at least a bottom wall and an outer side wall and has a generally L-shaped cross-section. A double-sided adhesive tape is bonded to an interior face of the outer side wall except for a predetermined area which ranges between both longitudinal ends of the connecting section.

Claims

1. A weather strip for a motor vehicle, which is capable of providing a seal between a closing member for closing an opening formed in a vehicle body and an opening portion of the vehicle body around the opening, comprising: a base portion which is adapted to be attached to a flange provided in one of the closing member and the opening portion of the vehicle body; anda seal portion integrally formed with said base portion for contacting the other one of the closing member and the opening portion, and sealing a gap between the closing member and the opening portion, wherein longitudinal ends of said weather strip are connected to each other via a connecting section into a ring-shaped configuration, said base portion has a generally L-shaped cross-section, and includes at least an outer side wall and a bottom wall, a double-sided adhesive tape is bonded to an approximately entire circumference of an interior face of said outer side wall except for a predetermined area inclusive of said connecting section, which ranges from one side of said connecting section to the other side thereof.

2. A weather strip for a motor vehicle as claimed in claim 1, wherein said predetermined area to which said double-sided adhesive tape is not bonded ranges from 100 mm to 200 mm.

3. A weather strip for a motor vehicle as claimed in claim 1, wherein said predetermined area to which said double-sided adhesive tape is not bonded has a projection which is continuously formed in a face facing said flange along an end of said outer side wall so as to extend in a longitudinal direction thereof.

4. A weather strip as claimed in claim 1, wherein said bottom wall in a lower part of said weather strip, including said predetermined area to which the double-sided adhesive tape is not bonded, is covered with a scuff plate.

5. A weather strip as claimed in claim 1, wherein said base portion is partly composed of a solid body with an L-shaped cross-section, and said seal portion is composed of a sponge body with a tubular configuration, and said solid body of said base portion is composed of a harder material than a material of a remaining part of said base portion.

6. A weather strip as claimed in claim 5, wherein said harder material is one of a hard rubber, a hard thermoplastic elastomer and a hard synthetic resin.

7. A weather strip as claimed in claim 1, wherein a caulking member is attached to an interior face of said bottom wall.
