Abstract

A metal carrier is embedded into trim, for providing proper rigidness in the transverse direction as well as in the longitudinal direction to the strip-like trim formed with rubber or plastics and the like. Transverse slots are formed in the strip-like sheet metal at given intervals in the longitudinal direction and a thin link portion and/or narrow width portion (sectional area in the transverse direction is small) is alternately formed at the top and bottom portions of the transverse slot. When an external force is applied to the metal carrier covered with rubber or plastics, the formed connecting links of the thin link portion and/or narrow width portion at top and bottom are broken, and the metal carrier becomes a continuous zigzag strip.

Dependent claims

A metal carrier to be embedded into rubber or plastic for use as trim, said metal carrier comprising:

an elongated metal strip, a plurality of transverse slots across said strip in the central portion thereof, and link means adjacent the central portion of said strip on each side thereof, each said link means being continuous and including a plurality of first link portions having a thickness equal to the thickness of said strip, a plurality of second thin link portions having a thickness less than the thickness of said strip, and a plurality of intermediate link portions having a thickness equal to the thickness of said strip for connecting said first and second link portions, wherein said link means are positioned with respect to said plurality of slots such that a said first link portion of said link means is adjacent to one end of a first of said slots and a said second thin link portion of said link means is adjacent to the other end of said first of said slots and a said second thin link portion of said link means is adjacent to the one end of a second one of said slots and a said first link portion of said link means is adjacent to the other end of the second of said slots wherein the first and second ones of said slots are adjacent to each other.
