Description

  The present invention relates to an automobile seat using a wire frame as a seat frame.

Recently, in a car capable of widening the cargo space, the second seat and the third seat have a double folding structure, and the seat frame has a tendency to adopt a wire frame structure.
The seat frame is framed by welding an appropriate number of vertical and horizontal wires to the main wire frame, so that the wire ends of the vertical and horizontal wires are the front and back surfaces of the main wire frame. As a result, it was necessary to protect the trim cover from the wire terminal by performing a terminal process of winding a protective tape around the wire terminal.
Such wire terminal processing is cumbersome, poor in workability, and difficult to reduce costs.
