Vehicle seat including improved adjustable side bolsters

摘要

A vehicle seat including a backrest portion and a seating portion, each having a pair of movable lateral bolster sections mounted on opposite sides thereof to its frame assembly, wherein a manual adjustment mechanism for each pair selectively and simultaneously moves its bolster sections in a controlled fashion between first and second lateral support positions and wherein the adjustment mechanism maintains the bolster sections in both the first and second lateral support positions. Each of the bolster sections includes a rigid paddle which is embedded in the body of resilient material and which is hingedly connected to the frame assembly. The adjustment mechanism includes a handwheel which upon rotation causes its corresponding paddles to pivot with respect to its frame assembly, either toward each other or away from each other depending upon the direction of rotation.
