COMPACT SEAT KINEMATIC

摘要

The present invention generally relates to passenger seats. Some embodiments are related to a compact seat kinematic for moving a seat from a retracted position to an extended position. In some embodiments an intermediate component may be provided for coupling between a lower frame and an upper seat portion. The intermediate component (230) may translate in a forward direction relative to the lower frame and may translate the upper seat portion in the forward direction relative to the intermediate component. Other embodiments relate to a seat backrest recline system that may provide constant ratio of speed and force and may forgo the need for calibration.

1. A seat kinematic for use with a seat having a lower frame portion and an upper seat portion and being moveable between a retracted position and an extended position, the seat kinematic configured to translate the upper seat portion relative to the lower frame portion when the seat transitions between the retracted position and the extended position, the seat kinematic comprising:
an actuator system comprising a first linear actuator, a second linear actuator, and at least one motor configured to drive the first linear actuator and the second linear actuator, the first linear actuator and the second linear actuator being parallel to each other; wherein the actuator system is configured to couple the lower frame of the seat to the upper seat portion of the seat; and wherein the actuator system is configured to move the seat between the retracted position to the extended position by:
1) translating the actuator system in a first direction relative to the lower frame by driving the first linear actuator using the at least one motor; and2) translating the upper seat portion in the first direction relative to the actuator system by driving the second linear actuator using the at least one motor.
