Description

This invention relates to a vehicle seat, and more particularly to a vehicle seat equipped with a ventilation device. To improve seating comfort, seats with an air conditioning function are known that are configured to blow air from the seat cushion to the occupant. For example, Patent Document 1 discloses a seat cushion pad having an internally formed ventilation passage and an air outlet on its upper surface, configured to allow air from the ventilation passage to be blown out through the air outlet. International Publication No. 2015/030195 This is a perspective view taken from the front at an angle, showing the appearance of a vehicle seat according to one embodiment of the present invention.This is a perspective view from the rear at an angle, showing the frame of a vehicle seat.This is an exploded perspective view showing the seat pad and ventilation unit of a vehicle seat.This is a bottom view showing the cushion frame with the blower attached.This is a top view of the blower.This is a front view showing the seat back pad.This is a plan view showing a seat cushion pad.This diagram shows the ventilation channels arranged in the second cushion pad material.This is a schematic diagram showing a vehicle with an occupant seated.This is a cross-sectional view along the line X-X in Figure 7.This is a cross-sectional view along the line XI-XI in Figure 7.This is a cross-sectional view along the line XII-XII in Figure 7. The configuration of a vehicle seat according to one embodiment of the present invention will be described below with reference to the drawings. However, the embodiments described below are for the purpose of facilitating understanding of the present invention and do not limit it. That is, the present invention can be modified and improved without departing from its spirit, and of course, equivalents thereof are included in the present invention. Furthermore, the descriptions below regarding the materials, shapes, and sizes of the components constituting the vehicle seat are merely examples and do not limit the present invention. In the following, we will describe a vehicle seat installed in a vehicle as an example of a vehicle seat, and explain its configuration. Furthermore, in the following explanation, "front-to-back direction" refers to the front-to-back direction of the vehicle seat, which coincides with the direction of travel when the vehicle is moving. Also, "seat width direction" refers to the width direction of the vehicle seat, which coincides with the left-to-right direction as seen from the perspective of an occupant seated in the vehicle seat. Also, "up-down direction" refers to the up-and-down direction of the vehicle seat, which coincides with the vertical direction when the vehicle is traveling on a horizontal plane. Furthermore, when simply referred to as "outside," it refers to the side closer to the outside when moving outward from the center of the vehicle seat, and when referred to as "inside," it refers to the side closer to the center when moving from the outside of the vehicle seat towards the center. Furthermore, unless otherwise specified, the following descriptions of the shape, position, and orientation of each part of a vehicle seat assume that the vehicle seat is in a seated position. <Vehicle Seat S> The basic configuration of the vehicle seat (hereinafter referred to as the vehicle seat S) according to this embodiment will be explained with reference to Figure 1. Figure 1 is a perspective view of the vehicle seat S, and for illustrative purposes, a portion of the vehicle seat S in Figure 1 is shown with the surface materials 1a to 3a removed. The vehicle seat S is mounted on the vehicle floor and is a seat on which the vehicle's occupants (seatees H) sit. In this embodiment, the vehicle seat S is used as a front seat, corresponding to the front seats of the vehicle. However, it is not limited to this; the vehicle seat S can also be used as a rear seat, and in vehicles with three rows of seats in the front-to-back direction, it can be used as a middle seat in the second row or a rear seat in the third row. As shown in Figure 1, the vehicle seat S mainly consists of a seat back 1, which is the backrest portion that supports the back of the occupant H; a seat cushion 2, which is the seat portion that supports the buttocks Hd of the occupant H; and a headrest 3, which is positioned above the seat back 1 and supports the head of the occupant H. The seat back 1, seat cushion 2, and headrest 3 are sometimes collectively referred to as the seat body Sh. The seat back 1 and seat cushion 2 are connected by sandwiching a reclining device 90 (see Figure 2). The reclining device 90 allows the seat back 1 to rotate relative to the seat cushion 2, and its tilt angle is adjustable. Furthermore, the vehicle seat S includes a rail device 70 that supports the seat body Sh so that it can move in the front-to-back direction relative to the vehicle floor. The rail device 70 is a d
