Automotive door sealing member and method for manufacturing the same
When an exterior portion is provided on an exterior surface of an extrusion-molded portion of a sealing member having the extrusion-molded portion and a mold-formed portion, while appearance is made favorable, the exterior portion is inhibited from being damaged. A glass run 20 includes an upper glass run edge 20 a which is extrusion-molded, a rear connecting part 20 f which is molded integrally with one end portion of the upper glass run edge 20 a , and an exterior portion 29 provided on an exterior surface of the upper glass run edge 20 a . A surface Si of the rear connecting part 20 g on an outside of a passenger compartment is located further outside than a surface of the exterior portion.
1. An automotive door sealing member being provided for an automotive door of an automobile having a passenger compartment, the automotive door sealing member comprising:
an extrusion-molded portion formed by extrusion molding, the extrusion-molded portion extending in a longitudinal direction from one end portion to an opposite end portion of the extrusion-molded portion, the longitudinal direction corresponding with a forward-rearward direction of the automobile;
a mold-formed portion formed integrally with an end surface of the one end portion of the extrusion-molded portion that faces in the longitudinal direction, such that the mold-formed portion is continuous with the extrusion-molded portion in the longitudinal direction; and
an exterior portion provided on an exterior surface of the extrusion-molded portion toward an outside of the passenger compartment, the exterior portion extending in the longitudinal direction such that an end of the exterior portion reaches the one end portion of the extrusion-molded portion,
wherein an outer surface of the mold-formed portion facing an outside of the passenger compartment is located further outside than an outer surface of the exterior portion at the end of the exterior portion, and
wherein:
the mold-formed portion is integrally formed with the end surface of the one end portion of the extrusion-molded portion at a connecting portion of the automotive door sealing member,
the end of the exterior portion extends to the connecting portion of the door sealing member and terminates at the mold-formed portion, and
a step is formed at the connecting portion between the outer surface of the mold-formed portion and the outer surface of the exterior portion at the end of the exterior portion, such that a surface of the step protrudes toward the outside of the passenger compartment and faces in the longitudinal direction.
2. The automotive door sealing member of claim 1 , wherein
a material of the exterior portion is harder than a material of the mold-formed portion.
3. The automotive door sealing member of claim 1 , wherein
a thickness of the step is in a range from 0.01 mm, inclusive, to 0.2 mm, inclusive.
