Abstract
A center armrest for rear seat backs of cars that comprises an armrest upper part and an armrest lower part that are joined together by means of a hinge located at an end face of the armrest. Within a hollow central portion of the armrest, a control mechanism is provided by which the thickness of the armrest is automatically adjusted when the armrest is swiveled down from an out-of-use position where it functions as part of the seat back into the armrest position.
Claims32
A motor vehicle seat comprising:
- a seat back (13) having left and right sections (16, 17) which define a generally rectangular intermediate space therebetween,
- an armrest (18) disposed in said intermediate space for movement between a folded up position between said left and right sections (16, 17) and a folded down position extending forwardly from the seat back (13),
- said armrest (18) being divided in a lengthwise direction into two parts (22, 23), one part forming a lower part (22) of the armrest and the other part forming an upper part (23) of the armrest when the armrest is in said folded down position,
- said upper part (23) of said armrest having a cushioned armrest surface (34) facing upwardly when the armrest is in said folded down position and extending substantially along the length of said upper part (23),
- a link (39) adjacent one end of said two parts (22,23) in the form of a hinged joint (39) having a pivot axis in fixed relation to said two parts (22,23) joining said two parts (22,23) together for relative pivotal movement about said hinged joint pivot axis, and
- a mechanism (26) for pivoting said two parts (22,23) relative to each other about said fixed hinged joint pivot axis and positioning ends of the two parts (22, 23) remote from the hinged joint (39) away from each other when the armrest is in the folded down position.

- a link (39) adjacent one end of said parts for joining said parts (22, 23) together for relative movement, and
- a mechanism (26) for positioning ends of the two parts (22, 23) remote from the link (39) away from each other when the armrest is in the folded down position,
- said mechanism (26) having at least one cam track (44) in at least one of the armrest parts (22,23) and a cam track (44) disposed in said upper part (23) of the armrest.
