Benefits of technology

[0008] The present invention has been accomplished to solve the above problems of the prior art. An object of the present invention is to provide an air flow device incorporated into a seat of a vehicle which has a good appearance, and the air flow performance of which is excellent.

Problems solved by technology

However, in the above conventional air flow device incorporated into a seat for vehicle use, a flow of air is sent into the vehicle passenger compartment from a large number of small holes formed in the seat skin.
Therefore, a large pressure loss is necessarily caused in the air passage.
Accordingly, it is difficult to ensure that a necessary volume of air can be blown out.
However, since the suction port and the exhaust port are seen by passengers, the device appearance is not good.

FIG. 4 is a partial sectional view showing a relation between a suction port 4 and a pocket cover 3 in the air flow device incorporated into a seat of a vehicle of the present embodiment. FIG. 5 is a front view of a suction port 4 of the air flow device incorporated into a seat of a vehicle, wherein this view is taken from a reverse side of a pocket cover 3.

[0038] The air flow device incorporated into a seat of a vehicle of the present embodiment includes: a seat 1 of a vehicle including a seating portion 1b in which a passenger is seated and also includin...

second embodiment

[0058] The air flow device incorporated into a seat for vehicle use of the second embodiment is different from the first embodiment in that the air flow device of the second embodiment includes a heat exchanger which is provided inside the seat and has a heat exchanging function so that the air in the vehicle passenger compartment 2 can be air-conditioned and blown out from the seat surface. The air flow device incorporated into a seat of a vehicle of the present embodiment will be explained by referring to FIGS. 6 to 8. FIG. 6 is a rear view showing a structure of an air flow device incorporated into a seat of a vehicle of the present embodiment. FIG. 7 is a schematic sectional illustration taken on line VII-VII in FIG. 6. FIG. 8 is a partial sectional view showing a relation between a suction port 4 and a filter 15 in the air flow device incorporated into a seat of a vehicle.

[0059] As shown in FIG. 6, the air flow device incorporated into a seat of a vehicle includes: a blower 5....

third embodiment

[0074] The air flow device incorporated into a seat of a vehicle of the third embodiment is different from the first embodiment in that the suction port 11 is arranged at a position opposite to the reverse side of the seat handle cover 10. The air flow device incorporated into a seat of a vehicle of the third embodiment will be explained referring to FIGS. 9 and 10. FIG. 9 is a rear view showing a structure of the air flow device incorporated into a seat of a vehicle of the present embodiment, and FIG. 10 is a partial sectional view showing the relation between a suction port 11 and a seat handle cover 10 of the air flow device incorporated into a seat of a vehicle of the present embodiment.

[0075] As shown in FIG. 9, the air flow device incorporated into a seat of a vehicle includes: a seat handle cover 10 for covering both end portions of the handle 29; and a suction port 11, which is provided on the seat surface opposite to the reverse face of the seat handle cover 10, wherein th...

Abstract

An air flow device incorporated into a seat of a vehicle comprises: a seat 1 of a vehicle including a seating portion 1b on which a passenger is seated and also including a seat back portion la against which passenger leans; a suction hole 4 open on a surface 7 of the seat of a vehicle, communicated with a vehicle passenger compartment 2; a suction air passage 6 formed inside the seat 1 of a vehicle, communicated with the suction hole 4; a blower 5 for forcibly generating an air current in the suction air passage 6; and a pocket cover 3 covering one portion of the surface of the seat 1 of a vehicle. Further, the suction hole 4 is arranged opposite to a reverse face 3a of the pocket cover. Due to the above constitution, it is possible to provide an air flow device, incorporated into a seat of a vehicle, which has a good appearance and an excellent air flow performance.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an air flow device incorporated into a seat of a vehicle which forces air from the vehicle passenger compartment through the seat. [0003] 2. Description of the Related Art [0004] Concerning this type air flow device incorporated into a seat of a vehicle, for example, the official gazettes of JP-A-2003-252036 and 2003-285628 disclose an air flow device in which an air current is blown out from a seat surface, into a vehicle passenger compartment, through an air passage formed in the seat. In this type air flow device incorporated into a seat of a vehicle, a flow of air is forcibly blown out into an air passage formed in the seat. The blast of air is blown out from a large number of small holes, which are formed on a seat surface communicated with the air passage formed in the seat, into the vehicle passenger compartment. [0005] In the air flow device incorporated into a seat of a vehi...
