The second engagement protrusion 152 is a protrusion protruding upward from the left-right center of the upper surface of the third body 113, and the second engagement protrusion 151 of the pad body 100 for the driver's seat (see FIG. 4). Similarly to the above), when viewed from the front side, it is formed into a substantially trapezoidal shape in which the distance between the left and right becomes narrower toward the upper side. On the other hand, the size (left and right length) of the second engagement protrusion 152 is smaller than that of the second engagement protrusion 151. Therefore, the second engaging protrusion 151 provided on the driver seat pad body 100 shown in FIG. 4 and the second engaging protrusion 152 provided on the passenger seat pad body 100 shown in FIG. Is different in size depending on the specification of the vehicle seat S, specifically, the location of the vehicle seat S in the vehicle.

  Further, the second portion 222 of the second cover member 220 is provided at its lower end with a second engagement concave portion 252 into which the second engagement convex portion 152 fits. The second engagement recess 252 is formed in a substantially trapezoidal shape when viewed from the front side, like the second engagement recess 251 (see FIG. 4) of the pad body 100 for the driver's seat. On the other hand, the size (left and right length) of the second engaging recess 252 is smaller than that of the second engaging recess 251 so that the second engaging protrusion 152 fits therein. Therefore, the sizes of the second engagement recess 251 and the second engagement recess 252 also differ according to the specifications of the vehicle seat S.

  According to the present embodiment described above, the first cover member 210 is fixed to the pad body 100, and the second cover member 220 is fixed to both the first cover member 210 and the pad body 100. Since 100, the first cover member 210, and the second cover member 220 are fixed to each other, the seat cushion pad 20 composed of a plurality of parts can be firmly integrated. Specifically, since the second cover member 220 is fixed to both the first cover member 210 and the pad body 100, the integrity of the seat cushion pad 20 is increased. In addition, since the first cover member 210 is fixed to both the pad body 100 and the second cover member 220, this also increases the integrity of the seat cushion pad 20. Furthermore, since the pad body 100 is fixed to both the first cover member 210 and the second cover member 220, this also increases the integrity of the seat cushion pad 20.

  In addition, the lower surface of the first cover member 210 is fixed to the upper surface of the pad body 100, and the lower surface of the second cover member 220 is fixed to both the upper surface of the first cover member 210 and the upper surface of the pad body 100. Since the upper and lower surfaces to which force is applied when a seated person sits on the passenger seat S are fixed to each other, the seat cushion pad 20 composed of a plurality of parts can be more firmly integrated. Moreover, since the second cover member 220 is placed on both the upper surface of the first cover member 210 and the upper surface of the pad body 100, the second cover member 220 can be supported by the pad body 100. As a result, it is possible to prevent the first cover member 210 from being crushed more than necessary and, for example, the air passage 21 (second air passage 21B) becoming narrow.

The boundary portion between the fitting convex portion 140 and the first engaging concave portion 240 can be covered with the second cover member 220. This makes it difficult for a seated person sitting on the vehicle seat S to feel the break formed by the boundary between the first engagement protrusion 140 and the first engagement recess 240, so that the seating feeling of the vehicle seat S is reduced. Can be improved.

  Further, since the first engaging convex portions 140 are plural including the first convex portion 141 and the second convex portion 142, and the first engaging concave portions 240 are plural including the first concave portion 241 and the second concave portion 242, these are omitted. By engaging them, the positions of the pad body 100 and the cover member 200 can be accurately determined.

  Further, since the first convex portion 141 and the second convex portion 142, and the first concave portion 241 and the second concave portion 242 have different shapes, for example, the first cover member 210 is arranged on the pad body 100. At this time, if the front-back direction of the first cover member 210 and the front and back (upper and lower) are incorrect, the first engaging convex portion 140 and the first engaging concave portion 240 do not engage properly, so the pad body 100 and the cover. The incorrect assembly of the member 200 can be suppressed.

  Further, since the first engagement protrusion 140 and the first engagement recess 240 are provided on the left and right inner sides of the side portions 20L and 20R, the first engagement protrusion 140 and the first engagement recess 240 are formed on the side portions. Since it is provided in the central portion 20C that is flatter than 20L and 20R, for example, as compared with the configuration in which the first engaging convex portion and the first engaging concave portion are provided on the inclined surfaces of the side portions 20L and 20R, The seat cushion pad 20 can have a simple structure.

  Further, since the pad main body 100 is provided with the second engaging convex portions 151, 152 and the second cover member 220 is provided with the second engaging concave portions 251, 252, the cover member 200 is overlaid on the pad main body 100. The positions of the pad main body 100 and the cover member 200 can be easily determined by engaging the second engaging convex portions 151, 152 and the second engaging concave portions 251, 252 when arranging them. Further, in the present embodiment, since the pad main body 100 is provided with the first engaging convex portion 140 and the first cover member 210 is provided with the first engaging concave portion 240, the second engaging convex portions 151, 152. By further providing the second engaging recesses 251, 252, the positions of the pad body 100 and the cover member 200 can be determined with higher accuracy.

  Further, the sizes of the second engaging convex portions 151, 152 and the second engaging concave portions 251, 252 are different between the vehicle seat S for the driver seat and the vehicle seat S for the passenger seat. For example, if the second cover member 220 for the passenger seat is to be arranged on the pad body 100 for the driver's seat, the second engagement protrusion 151 and the second engagement recess 252 will not engage properly. Therefore, it is possible to prevent erroneous assembly of the pad body 100 and the cover member 200 having different specifications.
