Description

{Cushion cover for air ventilation seat}

The present invention relates to a ventilation sheet cushion cover provided at the lower end of a cushion portion of a ventilation sheet of a vehicle to form a flow path of air.

Generally, a separate cover is provided on the lower end of the cushion portion of the ventilation sheet so as to allow air to flow through the ventilation sheet but not to be washed out.

In the prior art, a ventilation system was constructed using a rigid plastic cover. However, when a rigid cover made of a plastic material is used, there is a problem that a feeling of foreign body can be felt when the passenger seated on the seat, resulting in a decrease in the seating feeling. In addition, the plastic cover increases the manufacturing cost due to the injection mold cost invested for manufacturing the cover, and consequently leads to an increase in the unit price of the product, which causes a problem of lowering the cost competitiveness of the entire sheet product.

In addition, due to the difference in deformation amount due to different material properties from the seat pads, the cover is detached from the cushion portion at the time of seating, and the sealing performance is lost.

It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.
