Abstract: A molded structure body includes a base member including at least thermoplastic resin and a molded member. The base member includes a connection portion, a first surrounding portion provided close to the connection portion and having a first density, and a second surrounding portion provided close to the first surrounding portion and having a second density. The first density is higher than the second density. The molded member is connected to and molded with the base member by injection of melted resin to the base member, and the molded member is connected to the connection portion.

Abstract: A vehicle seat component includes a cushion member, and an upholstery member that covers the cushion member. The cushion member and the upholstery member are integrated together during molding of the cushion member. The upholstery member has a first portion that is air-permeable and that is arranged at a seating side, and a second portion that is laminated on the first portion and that prevents intrusion of a molding material of the cushion member. A thin section that is recessed toward the upholstery member is formed in a back surface of the cushion member.

Abstract: A seat back frame includes a main frame that forms a frame of a seat back of a main seat, and an auxiliary frame that forms a frame of a seat back of an auxiliary seat adjacent to the main seat in a width direction, and that is integrally formed with the main frame. The main frame has a first open portion that opens toward a side with the auxiliary seat in the width direction. An end portion of the auxiliary frame is a fitting structure that fits together with the first open portion, and a portion of the fitting structure is welded.

Abstract: The present plate-like fiber base material has fibers and a thermoplastic resin. The fibers are bound by the thermoplastic resin, and the fiber base material includes a plurality of areas that differ in basis weight. The fiber base material may have a cut, and the basis weight of a cut-surrounding area positioned around the cut may be higher than that of an area positioned around the cut-surrounding area. The present interior material has the fiber base material and a surface layer that is disposed on one side of the fiber base material.

Abstract: In an operating lever structure for a vehicle seat in which an opening through which a seat belt extends is provided adjacent to a seat cushion lifting and lowering mechanism and a fixed end portion of the seat belt is connected to a seat cushion frame, a lifter lever includes a plate-like extending portion that is coupled to the lifting and lowering mechanism and a protrusion portion. The plate-like extending portion extends toward a front of the seat. The protrusion portion extends from the front end of the plate-like extending portion toward the outside in the seat width direction. The protrusion portion protrudes from an outer shield through a first exposing port of the outer shield, installed to a side portion of the seat cushion.

Abstract: There is provided a seat gap hiding structure in a vehicle seat where a cutout portion is formed on a seat cushion to arrange a seat belt therein, and a strip-shaped member is provided on a seat cover to correspond to the cutout portion at a part of the cutout portion, which is other than an arrangement position of the seat belt to cover a gap around the seat belt. One end portion of the strip-shaped member is fixed to the seat cover and the other end portion thereof is movably fixed to the seat cover using an elastic member. When the strip-shaped member is moved from an original position where the strip-shaped member covers the gap of the cutout portion, the elastic member generates an elastic force to return the strip-shaped member to the original position.
