Abstract
An arm rest for a seat having a seatback and a seat bottom includes a housing rotatable relative to the seatback and a motor disposed within the housing and configured to maintain a position of the housing relative to the seat bottom during movement of the seatback relative to the seat bottom.
Claims14
An arm rest for a seat having a seatback and a seat bottom, the arm rest comprising:
- a housing rotatable relative to the seatback;
- a motor disposed within the housing and configured to maintain a position of the housing relative to the seat bottom during movement of the seatback relative to the seat bottom;
- and
- a first sensor configured to detect a number of revolutions of the motor.
1 more element
A seat comprising:
- a seat bottom;
- a seatback rotatably attached to the seat bottom;
- an arm rest rotatably attached to the seatback and including a housing;
- and
- an actuator disposed within the housing of the arm rest and including a motor and a screw, the actuator configured to move the arm rest relative to the seatback when the seatback is moved relative to the seat bottom to maintain a position of the arm rest relative to the seat bottom, the screw extending from and driven by the motor and configured to rotate a lever in contact with the seatback to adjust a position of the housing relative to the seatback.
2 more elements
A system for controlling a position of an arm rest relative to a seat having a seatback and a seat bottom, the system comprising:
- a first motor configured to adjust a position of the arm rest relative to the seatback;
- a second motor configured to adjust an angular position of the seatback relative to the seat bottom, the seatback movable between a number of angular positions relative to the seat bottom by the second motor;
- an arm rest control module configured to synchronize operation of the first motor with operation of the second motor to maintain a position of the arm rest relative to the seat bottom during and following movement of the seatback relative to the seat bottom between the number of angular positions;
- a first sensor configured to detect a position of the arm rest relative to the seatback and monitor the first motor;
- and
- a second sensor configured to detect a position of the seatback relative to the seat bottom and monitor the second motor.
