Abstract
A stowaway armrest for a seat assembly for a vehicle which is pivotable about a single pivot on a seat back between a normal horizontal use position adjacent the side of the seat assembly and a horizontal stowed position behind the seat back. The single pivot has a pivot axis which is skewed with respect to a horizontal plane and vertical planes extending laterally and longitudinally through the vehicle so that the armrest is caused to rotate through a predetermined arcuate path when pivoted between its use and stowage positions and vice versa.
Claims6
A seat assembly for a vehicle comprising:
- a seat cushion unit;
- a seat backrest unit;
- an armrest unit having a longitudinal axis laterally disposed above and substantially parallel tot he seat cushion unit when in a first use position, and having a longitudinal axis generally horizontal and adjacent to the rear of the seat backrest unit when in a second stowage position;
- a single pivot means for cooperatively securing the armrest unit to the seat assembly, said pivot means being oriented such that the armrest unit, when rotated about the pivot axis, follows a predetermined arcuate path between the first use position and the second stowage position, said predetermined arcuate path defined by the movement of a point at an end of the armrest remote from the pivot axis, said path, when originating from the first use position, is initially simultaneously upward and laterally away from the seat cushion unit and ending in a downward direction and toward the rear of the seat backrest unit, said armrest and pivot means being located substantially within the rear profile of the seat backrest unit and substantially behind the front surface of the seat backrest unit in the stowed position;
- and
- first and second stop means such that the armrest unit is precluded from any pivotal rotation extending beyond the corresponding first use position and the second stowage position.
A seat assembly for a vehicle comprising:
- a seat cushion unit;
- a seat backrest unit;
- an armrest unit comprising an elongate support structure, resilient cushion means, and aesthetic covering means, said armrest unit having a first use position wherein said support structure's longitudinal axis is laterally disposed above and substantially parallel to the seat cushion unit, and having a second stowage position, wherein said axis is generally horizontal and adjacent to the rear of the seat backrest unit;
- a single pivot means for cooperatively securing said armrest unit to the seat backrest unit, said pivot means having a pivot axis which is skewed to a horizontal plane and vertical planes extending laterally and longitudinally through the vehicle, thereby causing the armrest unit to rotate through a predetermined arcuate path between said first use and second stowage positions, said predetermined arcuate path defined by the movement of a point at an end of the armrest remote from the pivot axis, said path, when originating from the first use position, being initially simultaneously upward and laterally away from the seat cushion unit and ending in a downward direction and toward the rear of the seat backrest unit, said armrest and pivot means being located substantially within the rear profile of the seat backrest unit and substantially behind the front surface of the seat backrest unit in the stowed position;
- and
- stop means to prevent said arrest unit from rotating below the first use position.
