Weather strip and coupling structure of the same

A weather strip configured to be coupled to a sash of a door of an automobile, the weather strip comprising:

• a coupling part fixed between a first anchoring part and a second anchoring part provided on an outer periphery of an outer peripheral part of the sash of the door of the automobile, the first anchoring part being closer to an exterior of the automobile than the second anchoring part, and the second anchoring part being closer to an interior of the automobile than the first anchoring part;
• a hollow seal member integrally formed with an inner-cabin side of the coupling part, the hollow seal member configured to elastically contact a second surface of a door opening edge of a body panel, the hollow seal member not being fixed to the sash;
• an outer lip integrally formed with an outer-cabin side of the coupling part, the outer lip configured to make elastic contact with a first surface of the door opening edge of the body panel when the door is in the closed position, the first surface of the door opening edge of the body panel being closer to the exterior of the automobile than the second surface of the door opening edge of the body panel, and the second surface of the door opening edge of the body panel being closer to the interior of the automobile than the first surface of the door opening edge of the body panel;
• a pillar part configured to couple the coupling part with the hollow seal member;
• and
• a body seal lip provided on the hollow seal member, the body seal lip being configured to make elastic contact with the door opening edge of the body panel when the door is in the closed position.

A coupling structure in which a weather strip is coupled to a sash of a door of an automobile, the coupling structure comprising:

• (i) the weather strip, which comprises:
• a coupling part fixed between a first anchoring part and a second anchoring part provided on an outer periphery of an outer peripheral part of the sash of the door of the automobile, the first anchoring part being closer to an exterior of the automobile than the second anchoring part, and the second anchoring part being closer to an interior of the automobile than the first anchoring part;
• a hollow seal member integrally formed with an inner-cabin side of the coupling part, the hollow seal member configured to elastically contact a second surface of a door opening edge of a body panel, the hollow seal member not being fixed to the sash;
• an outer lip integrally formed with an outer-cabin side of the coupling part, the outer lip configured to make elastic contact with a first surface of the door opening edge of the body panel when the door is in the closed position, the first surface of the door opening edge of the body panel being closer to the exterior of the automobile than the second surface of the door opening edge of the body panel, and the second surface of the door opening edge of the body panel being closer to the interior of the automobile than the first surface of the door opening edge of the body panel;
• a pillar part configured to couple the coupling part with the hollow seal member;
• and
• a body seal lip provided on the hollow seal member, the body seal lip being configured to make elastic contact with the door opening edge of the body panel when the door is in the closed position, and a top end of the body seal lip being configured to come into contact with an oblique surface of the door opening edge of the body panel first as the door approaches the closed position;
• (ii) the second surface of the door opening edge of the body panel, the second surface being configured to make elastic contact with the hollow seal member of the weather strip when the door is in the closed position;
• (iii) the first surface of the door opening edge of the body panel, the first surface being configured to make elastic contact with the outer lip of the weather strip when the door is in the closed position;
• and
• (iv) the oblique surface of the door opening edge of the body panel, the oblique surface being configured to connect with the second surface and the first surface, and the oblique surface extending downwards toward the interior of the automobile such that the second surface and the first surface are formed on an uneven base.
