An opening trim weatherstrip includes: a mounting base portion which is mounted on a flange; and a hollow seal portion, which is configured to be brought into abutment with a door frame or an outer circumference of a door panel of a motor vehicle door to seal a gap between the motor vehicle door and a vehicle body opening portion circumferential edge, including: a hollow root portion which is formed from the mounting base portion; and a hollow extension portion which is provided so as to extend transversely outwards from the hollow root portion; wherein a deformation rigidity of the hollow extension portion at a portion where the opening trim weatherstrip is mounted on a portion of the vehicle body opening portion circumferential edge which lies near a door hinge is higher than a deformation rigidity of the hollow extension portion at the other portion.

An installation base member couples to an opening of an automobile body and has a substantially U-shaped cross section. A hollow seal member includes a first base root and a second base root which extend from an outer-cabin side wall of the installation base member. The hollow seal member in cross section protrudes from the first base root outwardly to a first turning point, curves toward a base root of the flange and connects with the second base root. A side of the first base root includes solid (dense) material. An interval between the first and the second base roots includes sponge material. A first border between the solid (dense) material of the side of the first base root and the sponge material is closer to an exterior of the automobile than the first turning point.

A door weather strip includes an installation base member operatively coupled on a peripheral edge of a door of an automobile and a hollow seal member integrally molded with an inner-cabin side of the installation base member. The hollow seal member makes elastic contact with a door opening edge of a body when the door is in a closed position. A prop forms a part of a wall of the hollow seal member. The prop is substantially linear in cross section and has a first protrusion formed on an end thereof. The protrusion protrudes toward the door and makes elastic contact with a panel of the door.

The prop is substantially linear in cross section, extends in an inner and outer cabin direction when the door is in the closed position and has a first protrusion formed on a first end thereof. The first protrusion protrudes toward the door from a part which closes the hollow wall and makes elastic contact with a panel of the door.

A retractable truck bed cover having an array of parallel aluminum slats joined together by connective hinges including leading and trailing edge configuration for improving the security of the cover by covering and concealing the seam between adjacent slats while improving the connective hinge's resistance to the effects of aging and/or exposure to temperature fluctuations. The truck bed cover connective hinge slat is designed to be in an array of discrete slats, which are joined to one another by means of joiner members secured at each end to slat end caps. The distal ends of the joiner members are attached to slat end caps at the distal ends of the slats, thereby preventing the joiner members from shrinking in relationship to the slats due to aging and/or exposure to temperature fluctuations.

A door weather strip for an automobile couples to a flange of a door of the automobile. The door weather strip includes an installation base member, a hollow seal member, an air vent, and a sponge layer. The installation base member couples to the flange. The hollow seal member is integrally molded with the installation base member, and makes elastic contact with an automobile body of the automobile when the door is in a closed position. The hollow seal member includes a first wall, a second wall, a third wall, and a fourth wall. The air vent is provided on the hollow seal member, and is used to release air from the hollow seal member. The sponge layer is provided on an inner peripheral surface of the hollow seal member except the air vent, and has a specific gravity lower than the first, second, third, and fourth walls.
