[0002]
[Prior art]
Conventionally, various types of cushions used in vehicle seats for the purpose of protecting this type of lumbar region have been developed. For example, a lumbar support attached to the inside of the seat cover of the seat so that the position can be adjusted vertically (patented) In order to lay so that the seat and the cushion seat are not detached, the seat back portion of the seat is used for suspending the waist pillow having a cushioning property from above the seat with a string (see Patent Literature 2). A mounting piece for mounting above the seat is provided, and a seat-like connecting portion that is inserted between the seat back portion and the seat seat portion of the seat is extended and inserted on the back surface (see Patent Document 3), A belt (see Patent Document 4) in which a belt is stretched near the back hem and a retaining member is attached to the free end of the belt is disclosed.

[Problems to be solved]
However, if the lumbar support is installed inside the seat cover so that the position of the lumbar support can be adjusted in the vertical direction, the lumbar support is installed inside the seat cover. Even if it is attached so that its position can be adjusted in such a case, it cannot be adjusted easily, and if a waist pillow with cushioning properties is hung with a string body, it is only for the waist, and there is no sense of stability and appearance In addition, if the seat-like connecting portion that is inserted between the seat back portion and the seat seat portion of the seat is extended and inserted on the back surface, it easily moves with the cushion and comes off. And in the case where a belt is stretched near the back hem of the cushion and a retaining member is attached to the free end thereof, the cushion is not easily removed from the seat, but the cushion is a conventional sponge. Stability which was used of a flexible material as a cushion material was a bad thing.
