Abstract:
1. An armrest for a motor vehicle seat comprising: a lower part; an upper part that carries an arm support surface; a first articulation device connecting the upper part to the lower part, said first articulation device having a rotational axis that extends perpendicular to a longitudinal axis of the armrest; a second articulation device connecting the upper part to the lower part that is spaced apart from the first articulation device, said second articulation device having a rotational axis and a translational axis, wherein the rotational axis of the second articulation device is perpendicular to the longitudinal axis of the armrest and the translational axis is approximately perpendicular to said arm support surface, said second articulation device including a first gear with a rotational axis oriented horizontally relative to the use position of the armrest and perpendicular to the longitudinal axis of the armrest, and a toothed rack engaging said first gear; said upper and lower arm rest parts being relatively movable in the direction of said translational axis between positions in which said upper and lower arm rest parts are in relatively separated relation to each and in which said upper and lower arm rest parts are in relatively close relation to each other, a locking device for locking the second articulation device in a desired adjusted position, a horizontal bearing shaft that extends in perpendicular relation to a longitudinal axis of the lower part for pivoting said upper and lower armrest parts upward and downward between a use position which is approximately horizontal and a rest position which is approximately vertical, and a control device activated by pivoting movement of the armrest for bringing the armrest into a position in which the upper part and the lower part lie in relatively close relation to each other.
