Abstract: A reclining mechanism cover for covering hinge portions (15) of a reclining mechanism in a vehicle seat includes a seat front right reclining mechanism cover (11) and a seat front left reclining mechanism cover (12) which cover, from the front of a seat back the hinge portions on the left and right sides in the width direction of the seat back; and a seat lower reclining mechanism cover (10) which comprises left and right rear reclining mechanism covers that cover, from the rear of the seat back, the left and right hinge portions (15) of the seat back and a seat back rear covering component that is integral with the seat back rear reclining mechanism covers. This reclining mechanism cover is mounted to the seat back frame (4) of the seat back via the seat lower reclining mechanism cover (10).

Abstract: The purpose of the present invention is to provide a reclining mechanism cover and vehicle seat using the same such that there are less components for the reclining mechanism cover and a seat rear cover component, component and assembly processing costs are reduced, and safety is improved so as to satisfy regulatory requirements. To achieve this, a reclining mechanism cover for covering hinge portions (15) comprise a seat front right reclining mechanism cover (11) and a seat front left reclining mechanism cover (12) which cover, from the front of a seat back the hinge portions on the left and right sides in the width direction of the seat back; and a seat lower reclining mechanism cover (10) which comprise left and right rear reclining mechanism covers that cover, from the rear of the seat back, the left and right hinge portions (15) of the seat back and a seat back rear covering component that is integral with the seat back rear reclining mechanism covers.

Abstract: A forward slippage preventive structure of seat cushion with lifter device, wherein a horizontal bar element, adapted for preventing forward buttocks slippage of seat occupant, is connected with two link members of the lifter device. A reinforcing flange element is formed in either of forward and backward ends of each of two link members in a direction inwardly of a seat cushion frame. Basically, one end portion of the horizontal bar element is connected integrally with such reinforcing flange element and one of the two link members, such that a truss structure is established thereamong. Based thereon, both end portions of the horizontal bar element are connected between two reinforcing flange elements.

Abstract: Impact absorption structure is provided in side frame element of seat cushion frame, wherein the side frame element has a vertical planar portion, an upper flange portion and a lower flange portion. A centroidal line is utilized as important factor, which extends along a vertical section of those vertical planar portion and upper and lower flange portions. Namely, an upper portion of the centroidal line is inclined by a certain angle toward a side inwardly of the seat cushion frame, and a module of section of said lower flange portion is smaller than a module of section of said upper flange portion, thereby allowing the side frame element to be deformed by impact load toward a side outwardly of the seat cushion frame and thus absorbing the impact load. For example, an inward extension may be merely formed in the upper flange portion to realize such impact absorption structure.

Abstract: A seat back of an automotive seat of the type having upper and lower seat-back sections, in which the upper seat-back section is formed independently of the lower one and further inclinable relative thereto. The connection between the upper and lower seat-back sections is designed so close as to avoid undesired part such as rift or gap therebetween. Further, a hole in that connection area is prevented from being viewed externally by an auxiliary covering member, and a "C"-shaped incision is formed at that connection area of padding, so that its lid may be taken out from or inserted back into its hole, for opening or closing the hole. With this structure, an outer aesthetic appearance of the seat is far improved.
