Abstract: A stretch fabric in which one yarn of warp and weft yarns is obtained from an inelastic yarn having a crimp ratio of 5% to 30% and at least a portion of the other is obtained from an elastic yarn having a crimp ratio of 0% to 5%, and characterized in that the extension percentage in a load direction along the former yarn is 5% to 30% when weighted with a 340N/5 cm load in the load direction. The stretch fabric has excellent cushioning properties and fatigue resistance, and can be used as a material that saves space and combines holding properties with cushioning properties.

Abstract: A projection welding structure including plural projection portions that are provided to an end face at an open side end portion of a reinforcement member flange portion and are disposed at intervals along the length direction of the reinforcement member. The plural projection portions are each abutted and welded to welding projections formed in a surface of a panel frame. Contact between the welding member and the welded member is suppressed at locations other than at the welding projections by such a structure.

Abstract: In a vehicle rear seat, slits are respectively formed in side wall portions of retainers provided on a vehicle body side and are respectively open at upper end sides of the side wall portions. Hinge pins respectively provided at lower end sides on side portions of a rear seat back are inserted in the corresponding slits to thereby couple the rear seat back to the vehicle body side via the retainers. Furthermore, in the vehicle rear seat, distal end sides of the hinge pins, that is, portions that protrude outward of the rear seat back, are respectively covered with covers attached to the corresponding retainers.
