## Abstract

A weather strip is capable of obtaining a fine external appearance at the center pillar, of meeting need of flush surfacing, of obtaining better feeling when a door glass is open and closed, of obtaining strong closable force of a door and of preventing water leakage. The weather strip includes a main seal, a door cutline seal which has a lip gap seal protruding from the upper surface thereof and a run channel which elastically contacts the upper end edge of a door glass, wherein the main seal and the lip gap seal respectively elastically contact an opening edge of a body except an upper portion of a center pillar and wherein the main seal, the door cutline seal and the run channel are respectively attached to a door sash. The weather strip further including a hollow body side weather strip which is attached to the upper portion of the center pillar so as to elastically contact a rear end edge of the door glass.

## Claims

### Claim 1

A weather strip comprising a main seal, a door cutline seal having a lip gap seal protruding from an upper surface thereof, and a run channel which elastically contacts an upper end edge of a door glass, wherein the main seal and the lip gap seal respectively elastically contact an opening edge of a body except an upper portion of a center pillar, and wherein the main seal, the door cutline seal and the run channel are respectively attached to a door sash, the weather strip further comprising a hollow body side weather strip attached to the upper portion of the center pillar to elastically contact a rear end edge of the door glass.

### Claim 2

A weather-strip for sealing a gap between an opening of a car body and a car door, the opening having an opening edge defined by at least a front pillar, a roof and a center pillar of the car body, the car door including a door frame and a door glass, the weather-strip comprising:
a main seal attached to an inner protruding portion of the door frame which elastically contacts the opening edge except for an upper portion of the center pillar;
a run channel seal attached to an outer portion of the door frame which elastically contacts the door glass when the door glass is in a fully raised position;
a door cutline seal engaged to an upper portion of the door frame outer portion, the cutline seal stopping a displacement of the run channel seal when the door glass is in the fully raised position, an end portion of the run channel seal and an end portion of the main seal both gradually taper toward the center pillar and are incorporated into the door cutline seal; and
a body-side weather strip attached to the upper portion of the center pillar which elastically contacts a rear end edge of the door glass.

### Claim 3 (depends on 2)

A weather strip as claimed in claim 2, wherein an upper end portion of the body-side weather strip is curved along the roof and thins toward a tip end thereof, the tip end being positioned against a lower portion of the tapered end portion of the main seal when the car door is in a closed position.

### Claim 4 (depends on 2)

The weather strip as claimed in claim 2, wherein the door cutline seal includes a lip gap seal protruding therefrom which contacts the front pillar and the roof.

### Claim 5 (depends on 2)

The weather strip as claimed in claim 2, wherein the main seal, the run channel seal and the door cutline seal constitute a door-side weather strip.
