Claims18
In combination, an apparatus for stitching an interior trim piece of a vehicle and the interior trim piece, wherein the interior trim piece comprises an outer skin layer, and wherein the apparatus is a single needle chain stitch machine with a rotary looper wherein the rotary looper extends from a portion of the apparatus such that a portion of the interior trim piece being stitched is located above and below the rotary looper as the rotary looper rotates and wherein a needle of the apparatus descends through the interior trim piece and a hook of the rotary looper engages a thread loop formed during retraction of the needle after it has descended through the interior trim piece;
- and wherein the apparatus further comprises a mechanism for moving the interior trim piece relative to the needle and looper to establish a stitch length.
In combination, an apparatus for stitching an interior trim piece of a vehicle and the interior trim piece, the interior trim piece comprising an outer layer, and wherein the apparatus has a rotatable looper arm extending therefrom, the rotatable looper arm being rotatably driven by a shaft and having a hook portion extended from the looper arm via an extension such that the hook portion of the looper arm can be inserted into an area of the interior trim piece having a portion of the interior trim piece located above and below the hook portion as it is rotatably driven by the shaft.
In combination, an apparatus for stitching an interior trim piece of a vehicle and the interior trim piece, the interior trim piece comprising an outer layer and wherein the apparatus has a rotatable arm member and a hook extending from the arm member, the arm member being rotatably driven by a shaft and the hook extends outwardly away from the arm such that the hook can be inserted into an area of the interior trim piece such that a portion of the interior trim piece is located above and below the hook as it is rotatably driven by the shaft.
