Description

Technical Field [0001] The present invention relates to an automatic forming apparatus for a pipe headrest frame,

The present invention relates to an automatic molding apparatus for a pipe headrest frame, and more particularly, to an automated production line capable of manufacturing a headrest frame of a seat with a pipe, thereby improving productivity and significantly reducing manufacturing cost and production cost. The present invention relates to an automatic molding apparatus for a pipe headrest frame.

Generally, a headrest of a vehicle seat supports the head at the top of the backrest, and is fixed at a predetermined height by being supported by a predetermined support frame attached to / detached from the backrest.

In this case, the headrest supporting frame according to the related art is formed of a round bar, and the end portion of the round bar is reduced in a chamfered shape so that it can be easily attached / detached to an engaging hole provided in the back of the seat.
