4results about How to "Protrusion suppression" patented technology

Provided is a sliding component capable of suppressing a rise in sliding surface temperature. Sliding components 10 and 20 have sliding surfaces 11 and 21 sliding relative to each other. A base material 22 of the sliding component 20 is directly coated with a thin film 30 mainly made of glassy carbon, and the sliding surface 21 is formed by the thin film 30.

An adhesive composition, wherein the adhesive composition is applied to obtain an adhesive coating layer having a complex viscosity of 10 Pa·s or more and 10,000 Pa·s or less at 25°C or more and 100°C or less, and the adhesive coating layer has a viscosity reduction rate of 80% or less determined by the following formula (1): Viscosityreductionrate%=V25−V100 / V25×100 wherein V25: Complex viscosity at 25°C, and V100: Complex viscosity at 100°C.

Provided is a sliding component capable of obtaining a stable low-friction effect in a wide range of conditions of use. Sliding components 10 and 20 have sliding surfaces 11 and 21 sliding relative to each other. A base material 22 of the sliding component 20 is directly coated with a thin film 30 mainly made of graphite, the sliding surface 21 is formed by the thin film 30, and the thin film 30 contains fillers 40 and 41 with dimensions equal to or less than the thickness of the thin film 30.

This invention provides a seat back that adequately ensures the thickness of the headrest cushion to enhance protection for the head or neck of the occupant. The seat back of this invention includes: a seat back frame (10) serving as the skeleton of the seat back; a headrest (30) supporting the head of the occupant; and a headrest post (40) attached to the upper part of the seat back frame and supporting the headrest, wherein the headrest post has: a fixing portion (41) fixed to the upper front surface of the seat back frame; and a first curved portion (42) extending rearward from the fixing portion.
