Abstract

A weather strip is provided. The weather strip is arranged so as to intersect a portion joined by overlapping a plurality of panels, and is provided with a tip projection portion which projects onto an extension line of the exterior side wall portion from the tip of an exterior side wall portion of an attachment portion. The tip projection portion is formed from a material which deforms easier than a material forming the sealing portion and is formed in a shape which becomes thin towards a projecting direction with a width dimension which does not exceed the thickness of the tip of the exterior side wall portion in a cross section along the width direction of the attachment portion, and when the attachment portion is attached to the flange, the tip projection portion stretches in the longitudinal direction of the attachment portion and comes into contact with the panels.

Claims

1. A long weather strip made of a polymer material comprising:

an attachment portion formed in a shape having an exterior side wall portion, an interior side wall portion, and a base bottom portion connecting together both the side wall portions so as to be attached to a flange provided along the circumferential edge of an opening of a vehicle body formed by a plurality of panels, and

a sealing portion provided at one of the side wall portions or the base bottom portion of the attachment portion, and

being arranged between the circumferential edge of the opening and a lid capable of opening/closing the opening to seal a gap between the circumferential edge of the opening and the lid,

wherein the weather strip is arranged so as to intersect a portion joined by overlapping the plurality of panels, and is provided with a tip projection portion which projects onto an extension line of the exterior side wall portion from the tip of the exterior side wall portion of the attachment portion,

wherein the tip projection portion is formed from a material which can deform more easily than a material forming the sealing portion, and the tip projection portion is formed in a shape which becomes thin towards a projecting direction with a width dimension which does not exceed the thickness of the tip of the exterior side wall portion in a cross section along the width direction of the attachment portion, and

when the attachment portion is attached to the flange, the tip projection portion comes into contact with the panels from its tip, and compressively deforms gradually in the projecting direction so as to be broadened in the width direction of the attachment portion so that a width dimension after deformation becomes greater than a width dimension before the deformation, and the tip projection portion stretches in the longitudinal direction of the attachment portion and comes into contact with the panels.

2. The weather strip according to claim 1,

wherein the tip projection portion is formed so that the width dimension and a height dimension thereof becomes 1:

1 in the cross section.

3. The weather strip according to claim 1,

wherein the tip projection portion is formed in a shape which is line-symmetric in the width direction in the cross section.

4. The weather strip according to claim 1,

wherein the tip projection portion is formed in a triangular shape which becomes thin towards the projecting direction in the cross section.

5. The weather strip according to claim 1,

wherein a rubber material forming the sealing portion has a smaller specific gravity than a rubber material forming a main portion of the attachment portion, and a rubber material forming the tip projecting portion has a smaller specific gravity than the rubber material forming the sealing portion.

6. The weather strip according to claim 1,

wherein the tip of the exterior side wall portion is formed with a joining portion which is joined to the tip projection portion, and is thicker than a main portion of the exterior side wall portion in the cross section.

7. The weather strip according to claim 1,

wherein the tip of the exterior side wall portion is formed so that the surface thereof joined to the tip projection portion is curved in a recessed shape in the cross section.

8. The weather strip according to claim 1,

wherein the tip projection portion is enabled to compressively deform more than the height difference of a portion joined by overlapping the plurality of panels.

9. An attachment structure of a long weather strip made of a polymer material,

the weather strip including an attachment portion formed in a shape having an exterior side wall portion, an interior side wall portion, and a base bottom portion connecting together both the side wall portions so as to be attached to a flange provided along the circumferential edge of an opening of a vehicle body formed by a plurality of panels, and a sealing portion provided at one of the side wall portions or the base bottom portion of the attachment portion, and the weather strip being arranged between the circumferential edge of the opening and a lid capable of opening/closing the opening to seal a gap between the circumferential edge of the opening and the lid,

wherein the weather strip is arranged so as to intersect a portion joined by overlapping the plurality of panels, and is provided with a tip projection portion which projects onto an extension line of the exterior side wall portion from the tip of the exterior side wall portion of the attachment portion, and

wherein the tip projection portion is formed from a material which can deform more easily than a material forming the sealing portion, and the tip projection portion is formed in a shape which becomes thin towards a projecting direction with a width dimension which does not exceed the thickness of the tip of the exterior side wall portion in a cross section along the width direction of the attachment portion, and

when the attachment portion is attached to the flange, the tip projection portion comes into contact with the panels from its tip, and compressively deforms gradually in the projecting direction so as to be broadened in the width direction of the attachment portion so that a width dimension after deformation becomes greater than a width dimension before the deformation, and the tip projection portion stretches in the longitudinal direction of the attachment portion and comes into contact with the panels.
