  • Patent number: 11572729
    Abstract: A protector with a sensor couples to a sliding door. A first end of an insert made of a non-conductive material is inserted in and fills up a space on a hollow part of the protector, and a terminal part is into die molding. The insert includes at least two feeding ports to receive and feed molding material into the insert during die molding. The feeding ports are spaced from each other and formed along a direction in which a wire harness extends. Covered parts are exposed from the wire harness where the covered parts are faced with the feeding ports.

  • Publication number: 20220325570
    Abstract: An inner-cabin side part of a hollow part of a protector with a sensor extends between a top end and an inner-cabin side end with an inner-cabin side apex closest to an interior of an automobile body. An outer-cabin side part of the hollow part extends between the top end and an outer-cabin side end with an outer-cabin side apex closest to an exterior of the automobile body. Distances are shorter between the apexes and the ends than between the top end and the apexes. A first conductive part includes parts closer to an installation base member than an apex of a second conductive part. Lower ends of the first conductive part have protrusions formed. The protrusions extend to protrude toward the second conductive part from an inner surface of an outer coat of the hollow part and are formed on uneven bases.

  • Patent number: 11433746
    Abstract: A protrusion is formed on a first part of an inner-cabin side wall of an installation base member of a protector with a sensor. The first part is closer to a connecting wall than a second part opposite the first part. The protrusion is on a virtual line in cross section. The virtual line is where convex substances, keys for example, hanging on passengers' clothes conceivably pass through. The virtual line extends toward a connecting point from a rear part of an automobile body closer to an interior of the automobile body than a reference line. The reference line is parallel with a direction in which a flange protrudes and extends from the connecting point. The connecting point is a part of an inner-cabin side end of a hollow part closest to an interior of the automobile body. The inner-cabin side end is connected with the installation base member.

  • Patent number: 11420504
    Abstract: A part of a touch sensor, which couples to a curve of a flange, includes a raising member. The curve of the flange is on a belt line of a sliding door. The raising member rises outwardly toward an exterior of the automobile from an inner-cabin side wall of the touch sensor. A space is formed between the raising member and an outer-cabin side wall for the flange to be inserted into the space. The raising member includes a plurality of blocks. The plurality of blocks exist along an upper and lower direction of the automobile body.
