Abstract

Provided is a door weather strip that provides excellent closing performance of a door and sound insulation properties, and does not impair the appearance. A door weather strip includes a mounting base and a hollow seal portion. The mounting base has a hole penetrating the mounting base, and the hole is mounted with a valve penetrating the mounting base. At the time of manufacturing a vehicle, the door is closed with the valve open, so that the air within the hollow seal portion is discharged to compress and shape the hollow seal portion (first step). When the door is opened, the valve is closed to retain the shaped state of the hollow seal portion (second step). The valve is opened again at a time point when the hollow seal portion begins to come into contact between the door and the vehicle body opening while the door is closing, or at a time point when the door is closed (third step).

Claims7

Dependent claims

A door weather strip that is mounted to a door of a vehicle or a peripheral edge of a vehicle body opening to seal a gap between the door and the peripheral edge of the vehicle body opening,

the weather strip comprising a mounting base and a hollow seal portion, the mounting base being mounted to the door or the peripheral edge of the vehicle body opening, wherein
the mounting base has a hole penetrating the mounting base,
the hole is mounted with a valve for discharging the air within the hollow seal portion or sucking air into the hollow seal portion, which penetrates the mounting base,
the door weather strip involves:
a first step in which, after mounting of the manufactured door weather strip to the door or the peripheral edge of the vehicle body opening, the door is closed with the valve open, and the hollow seal portion is compressed between the door and the peripheral edge of the vehicle body opening, and shaped;
a second step in which, when the door starts to open, the valve is closed, and, when the door is open, the valve remains closed to substantially retain the shaped state of the hollow seal portion;
and
a third step in which the valve is opened at a time point when the door starts to close and the hollow seal portion starts to come into contact between the door and the vehicle body opening while the door is closing, or at a time point when the door is closed, and
the weather strip shaped by the first step is subjected to alternate repetition of the second step and the third step in association with the opening and closing of the door.

An operating mechanism for a door weather strip that is mounted to a door of a vehicle or a peripheral edge of a vehicle body opening to seal a gap between the door and the peripheral edge of the vehicle body opening, wherein

the weather strip includes a mounting base and a hollow seal portion, the mounting base being mounted to the door or the peripheral edge of the vehicle body opening,
the mounting base has a hole penetrating the mounting base,
the hole is mounted with a tube for discharging the air within the hollow seal portion or sucking air into the hollow seal portion, which penetrates the mounting base,
the door weather strip involves:
a first step in which, after mounting of the manufactured door weather strip to the door or the peripheral edge of the vehicle body opening, the door is closed with the air within the hollow seal portion allowed to flow through the tube, and the hollow seal portion is compressed between the door and the peripheral edge of the vehicle body opening, so that the air within the hollow seal portion is discharged through the tube to shape the hollow seal portion;
a second step in which, when the door starts to open, flow of the air within the tube is stopped with the door open to substantially retain the shaped state of the hollow seal portion;
and
a third step in which the air within the hollow seal portion is allowed to flow through the tube at a time point when the door starts to close and the hollow seal portion starts to come into contact between the door and the vehicle body opening while the door is closing, or at a time point when the door is closed, so that air is allowed to be sucked into or discharged from the hollow seal portion, and
the weather strip shaped by the first step is subjected to alternate repetition of the second step and the third step in association with the opening and closing of the door.
