Abstract: A first laminated body is worked to form a second laminated body, the first laminated body being formed by laminating prepregs including reinforcing fibers and resin, the second laminated body including a flat portion and a wavy portion, the flat portion being located at at least one of side edge portions of the second laminated body, the wavy portion being located at a portion adjacent to the side edge portion and extending along a longitudinal direction. An intermediate product is formed from the second laminated body by a forming die such that the flat portion becomes a bent portion that is an inside portion whose circumferential length is shorter in a curved portion, and the wavy portion becomes a bent portion that is an outside portion whose circumferential length is longer in the curved portion.

Abstract: A brake device for a motor vehicle seat is composed of a brake assembly, a tooth assembly, and a lever assembly. The brake assembly includes a housing, a pinion shaft, a braking component, and a drive wheel that are structured to be self-held in an assembled state by mechanical interaction thereamong. The tooth assembly includes a holder plate and a tooth plate that are structured to be self-held in an assembled state by mechanical interaction therebetween. The lever assembly includes an input lever, a cover, a coil spring, and a lever bracket that are structured to be self-held in an assembled state by mechanical interaction thereamong. The brake assembly, the tooth assembly, and the lever assembly are arranged and assembled together in an axial direction.

Abstract: A brake device for a motor vehicle seat includes a braking section for holding a pinion shaft in a braked and locked state. The braking section includes a housing including an inner periphery including a braking surface. First and second lock plates are arranged opposite to each other with respect to the pinion shaft in the housing. The pinion shaft includes a rectangular shaft part disposed between the first and second lock plates, wherein the rectangular shaft part includes an acting surface structured to be in contact with the first lock plate. The first lock plate is pressed on the braking surface of the housing by the acting surface. The acting surface includes a crest line corresponding in position to the center of the pinion shaft, and an inclined surface that descends from the crest line toward a radially outward end of the rectangular shaft part.

Abstract: A brake device comprises a brake mechanism which comprises an output shaft having a drive gear secured thereto, a brake housing having a cylindrical braking surface therein and coaxially putting therein the output shaft, two pairs of clamp members movably and abreast installed in the brake housing in such a manner that paired two clamp members of each pair put therebetween an enlarged operation part of the output shaft and two springs that bias the two clamp member of each pair to pivot away from each other, in which each of the clamp members has an outer clamp surface that is slidably contactable with the cylindrical braking surface and includes larger and smaller clamp surface areas that are spaced from each other by a recess.

Abstract: An electrically operated seat slide apparatus includes a lower rail fixed to a floor of a vehicle body, and an upper rail slidably disposed to the lower rail. A seat is connected to the upper rail. A screw shaft is disposed inside the upper rail. A nut is threadedly connected to the screw shaft and connected to the lower rail. A motor is disposed to side of the upper rail. A gear box is fixed to the upper rail to transmit a rotation of the motor to the screw shaft. Additionally, first and second plates are provided for allowing an impact load applied to the upper rail to be directly transmitted to the screw shaft so as to prevent the impact load from being transmitted through the gear box to the screw shaft, and for setting a moving range of the nut.
