摘要： PROBLEM TO BE SOLVED: To provide a reciprocating slide type air seal mechanism in which abrasion progress of an air seal material is reduced, and a sliding material used therefore.
SOLUTION: In an air seal mechanism, air seal is executed by reciprocating slide contact between an air seal material and a sliding material, wherein the priority of slide abrasion is given to the air material relative to the sliding material. In the evaluation standard of the sliding surface of the sliding material where the evaluation length is 2.5 mm and the cut off is 0.25 Gaussian, the following relations are satisfied : Wca obtained from the cross section curve: ≤0.30μm, Ra obtained from the roughness curve: ≤0.25μm, and load length ratio tp: ≤20% at 20% of the cut ratio and ≥50% at 30% of of the cut ratio.

摘要： PROBLEM TO BE SOLVED: To provide a lightweight seat frame structure capable of mitigating a bending load acting on a seat back frame and free of restriction on the reclining extent. SOLUTION: A seat back frame 18 is coupled with a seat recliner 26 by a seat back side bracket 24 fixed to near the bottom. A wire 28 is set over between the seat back plate 18 and bracket 24. Because the part or the whole of the bending load applied to the seat back frame 18 acts on the wire 28 as a tensile load, stresses in the fixation part 18A of the frame 18 are reduced. This allows reducing the diameter of the frame 18 and also its weight. As the wire 28 rotates in a single piece with the frame 18 and bracket 24, there is no restriction imposed on the reclining angle of the seat back 14.
