Ventilation apparatus for vehicle seat

Abstract

A ventilation apparatus may include a vehicle seat, wherein the vehicle seat is configured by a seat cushion and a seat back, wherein the seat back is configured by a metal frame, a back board, and a skirt to eject air to the vehicle seat using a cushion duct and a back duct which are varied in length by a connection duct without a change in cross-sectional area of an internal passage through which air passes along the movement of the seat cushion therein, and the back duct and the cushion duct are connected to the skirt by a fixing means while a portion of the back duct and a portion of the cushion duct are covered by the connection duct.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application claims priority to Korean Patent Application No. 10-2020-0073668, filed on Jun. 17, 2020, in the Korean Intellectual Property Office, the entire contents of which is incorporated herein for all purposes by this reference.BACKGROUND OF THE INVENTIONField of the Invention[0002]The present invention relates to a ventilation apparatus for a vehicle seat. More specifically, the present invention relates to a ventilation apparatus for a vehicle seat configured for maximally utilizing a space inside a seat back by integrating a back duct and a cushion duct which are independently disposed in the related art with a skirt, respectively.Description of Related Art[0003]In general, since a vehicle seat in use is not provided with a separate ventilation apparatus, during the summer or winter, a vehicle occupant had no choice but to receive hot and cold air delivered from a seat.[0004]Therefore, as a solution to solve the present...

AI Technical Summary

Benefits of technology

[0015]The present invention having the above configuration can obtain the following effects.

[0016]First, it is possible to maximally utilize a space inside the seat back by configuring a conventional back duct integrally with the back board.

[0017]Second, it is possible to enhance the productability of the seat by improving an occupancy (legroom) of the passenger and an appearance.

[0018]Third, it is possible to improve the performance by maximizing the cross-sectional area of the duct by securing the space in the seat.

[0019]Fourth, it is possible to prevent interference with the passenger's foot located in the rear seat while maintaining the duct shape, by use of a soft material for the connection duct.

Problems solved by technology

Due to the dual structure of the steel frame and the duct configured as described above, there was a problem in that when the ventilation specification is applied, a duct mounting portion is vulnerable to cause a flow of the duct during vehicle operation, and when seating the passenger, the duct is pressed against the body of the passenger, deteriorating the ventilation performance.

However, as illustrated in FIG. 2, there is a problem in that when a foot of a rear passenger is in contact with a portion through which the duct passes, the rear passenger feels a foreign body and a leg room is reduced, or a space in the seat back is narrowed due to the installation of the duct.

Moreover, due to a need of securing a duct mounting space while simplifying the complex structure as described above, the slimness of the seat back is reduced and there is difficulty in increasing the legroom of the rear seat.
