を特徴とする座席の背凭れに存する。"Means for Solving the Problems" The gist of the present invention for achieving the above object is to have a pad material integrally molded and a cover member covering the rear part, and the pad material and the cover member are integrally formed. In a seat backrest in which a component is disposed in a space between the pad material and the cover member, a protective protrusion having a higher elastic resistance to compressive deformation than the dimension occupied by the component is provided on the pad material. A recess is formed between the protective protrusions to accommodate the constituent member at intervals, and is integrally protruded from the rear surface of the pad material toward the cover member so as to be continuous over the entire rear surface. It is located on the backrest of the seat.

る。 From the rear surface 33 of the pad material 30, horizontal rib-shaped protective protrusions 34, 34, etc. protrude rearward from the rear surface 33.
The protective protrusion 34 extends between the zigzag springs 21 and 21 and faces the inner surface 43 of the garnish 40.
The height is equal to that of the zigzag spring 21 or the supply/discharge pipe 32 of the air bag 31.
The protective protrusions 34, 34... are set larger than the dimensions occupied by the protective protrusions 34, 34, and have elastic resistance against compressive deformation, and a recessed portion is formed between the protective protrusions 34, 34, . has been done. One protective protrusion 34 is provided with a notch 35 through which the supply/discharge pipe 32 of the air bag 31 is passed.

受け止められる。 If a seated person leans strongly against the front of the backrest 10 or a large load is applied to the rear due to an impact, etc., the central part of the pad material 30 and the zigzag spring 2
1 is pushed strongly backwards and is greatly displaced. Then, the protective protrusions 34, 34... are displaced toward the garnish 40, and then move toward the inner surface 43 of the garnish 40.
The protection protrusion 34 itself is compressed and deformed, and its elastic force is added to the elastic force of the pad material 30 and the zigzag spring 21, so that the load from the seated person is absorbed.
保護突起３４，３４，…がガーニツシユ４０の
内面４３に当つて突つ張るので、相当に大きな荷

損壊したりすることはない。 Since the protective protrusions 34, 34, .
A minimum space is secured between the rear surface 33 of 0 and
The zigzag spring 21 is attached to the inner surface 43 of the garnish 40.
The air bag 31 will not be pinched between the air bag 31 and the rear surface 33 of the pad material 30, causing abnormal noises, and the supply/discharge pipe 32 of the air bag 31 will not be pinched and damaged.
