Vehicle seat having arm rest adjustment means

摘要

A vehicle seat comprises a pair of laterally spaced apart support plates, a pair of laterally spaced apart arm rests, and independently adjustable arm rest support assemblies for adjustably supporting each arm rest on an associated support plate so that each arm rest can be shifted and also pivoted to different positions in a vertical plane. Each arm rest assembly comprises a pair of elongated support links; a link plate; and pivot means for pivotably connecting the link plate and one end of one elongated support link to the arm rest whereby the arm rest can be pivoted to different positions thereabout. The other elongated support link has one end pivotally connected to the link plate and its other end pivotally connected to the support plate. Adjustable connector means are provided for connecting the other end of the said one support link to the support plate and comprise: a ring gear connected to the other end of the said one support link; a spur gear engaged with the ring gear; an eccentric pin connected to the spur gear; means for rotatably connecting the eccentric pin to the support plate; and a control knob connected to the eccentric pin and adjustably rotatable to effect rotation of the eccentric pin and spur gear and planocentric rotation of the ring gear, whereby the said one support link and the arm rest attached thereto are shiftably movable to desired locked positions relative to the support plate.
