Abstract: A reclining seat having a U-shaped back frame of a seat back thereof and a base frame of a seat bottom thereof. End portions of the back frame are connected to connecting means provided in the base frame for connecting to the back frame so as to rotate the back frame with respect to the base frame. At least one of the connecting means has a rotating member provided for adjusting and fixing a tilt angle of the seat back with respect to the seat bottom. The rotating member has a shape corresponding to a circumference of the end portion and has means for temporarily attaching the back frame to the base frame, and the temporarily attaching means have a hook. The circumference of the end portion has an entrance for entering and receiving the hook. When the end portion of the back frame is connected to the connector of the base frame, the hook is entered and received in the entrance, and thereby, the back frame is temporarily attached to the base frame.

Abstract: A seat having various hardnesses provided with a surface material. The seat is air-permeable, has a tactile feeling of the seat surface and has a hardness capable of supporting the weight of a person who sits thereon. The seat (1) is covered with an air-permeable surface material (2) and has a foamed body having a shape generally corresponding to an external shape of the seat. The foamed body includes a first foamed body (10) as a base of the foamed body and a second foamed body (6) connected integrally with the first foamed body. The first foamed body (10) has ascending parts (12, 13) which are formed on parts of a surface thereof. In the method for manufacturing the seat, the mixture (15) is introduced and layered on the first foamed body (10) and the surface material (2) is placed thereon.
