no. 2 approach

[0068]This embodiment is a modified example based on the previous embodiment. In the above embodiment, the RAS 20 has the vertical duct 23 and the horizontal duct 24 . In addition, a part of the duct of the RAS 20 may be formed by the seat pad 32 .

[0069] Figure 8 equivalent to Figure 7 . In the present embodiment, the air passage 221 is divided by the recessed portion 32 b of the seat pad 32 and the cover member 234 . The cover member 234 may be provided from the same material as the seat pad 32 . The air passage 221 corresponds to the air passage 23a provided by the vertical duct 23 of the previous embodiment. Air from the blower 22 passes through the air passage 221 and reaches the horizontal duct 24 . In this case, a smooth resin layer may also be provided on the surface of the concave portion 32 b and the cover member 234 . According to the present embodiment, a part of the RAS 20 provided on the outer side of the frame 31 can be provided by the seat pad 32 . ...

no. 3 approach

[0071] This embodiment is a modified example based on the previous embodiment. In the above-described embodiment, the RAS 20 sucks air from the space between the frame 31 and the seat pad 32 . Besides, the RAS 20 can also suck air from the gap of the frame 31 .

[0072] Figure 9 equivalent to image 3 . In this embodiment, the frame 31 has a plurality of gaps 331f. The gap 331f can be provided in various shapes such as a through hole opened in the frame 31, a notch, a gap between two members, and the like. The gap 331f provides an entry path from the frame space through the frame 31 to the inlet 22d. The gap 331f may be an opening formed to reduce the weight of the frame 31 . In addition, the gap 331f may be an opening provided for the frame 31 to function as the frame 31 for the seat 6a. The air blower 22 is arranged so that the inlet 22d communicates with the gap 331f. According to this embodiment, even if it is the structure which sucks in air from the inside of th...

Abstract

A seat (6) has a blower device (RAS) for a rear seat. The RAS has a blower (22) disposed between a frame (31) and a surface material layer. The RAS has a member for defining and forming an air passage(21) extending from the blower along the outside of the frame. The member is formed from a vertical duct (23) and a horizontal duct (24). The RAS has a member for defining and forming a discharge opening from which air supplied from the air passage is discharged toward the rear seat. The member is formed from the horizontal duct. The frame of the seat is prevented from being adversely affected bythe blower and the air passage. The provided blower device for a rear seat discharges air toward the rear seat without impairing the fundamental function of the frame for the seat.
