CONNECTING STRUCTURE OF CONNECTOR FOR SEAT VENTILATION APPARATUS AND MANUFACTURING DEVICE OF THE SAME

The present invention relates to a connector connection structure for a ventilation mechanism of a seat and a manufacturing apparatus therefor, and relates to a connection structure between a corrugated pipe and a connector located between a seat pad of a ventilation seat and a duct of a seat frame and a method for manufacturing the same.

The seat of the vehicle should be designed to minimize the passenger's fatigue despite the driver's long driving.

Recently, various convenience devices are installed on the seat of a vehicle to increase the value and functionality of the vehicle. For example, a hot-heated seat having a heater function on the seat is typical. In addition to this, recently, there has been active development of a ventilation sheet that forcibly flows air for comfort of a sheet, and a plurality of holes are provided to blow air out of the sheet and blown air out of the sheet to the outside of the sheet. It is generally composed of a formed sheet pad.

A flow path through which the plurality of holes communicate is formed in the seat pad of the ventilation sheet to evenly distribute the air introduced into the seat pad, and the flow path is connected to a blower and serves to distribute air.

In order to connect the external air introduced from the blower to the flow path of the seat pad, a corrugated pipe in which a plurality of films are fused is located under the seat pad, and the corrugated pipe is connected to the blower through a connector.

However, in the related art, a method in which an operator applies an adhesive by applying an adhesive between the connector and the corrugated pipe has been used, resulting in assembly variation and strength difference, and due to poor adhesion, external air leakage occurs when the ventilation function is operated. The problem occurred.

The above descriptions as background arts are only for improving understanding of the background of the present invention, and should not be accepted as acknowledging that they correspond to the prior arts already known to those skilled in the art.
