Abstract: A gear assembly includes motor, a first gear, one or more planet gears, a first ring gear, and/or a second ring gear. The motor may be configured to rotate the first ring gear at a first speed and/or a second speed. The first gear may be configured to rotate the one or more planet gears. The planet gears may be configured to engage the first ring gear and/or rotate the second ring gear. The second speed may be greater than the first speed. Each of the one or more planet gears may include a first portion and/or a second portion. The first portion may include a first radius, and/or the second portion may include a second radius. The first radius may be larger than the second radius.

Abstract: A foldable vehicle includes a seat base, a seatback connected to the seat base for pivotal movement relative to the seat base from a generally vertical use position to a generally horizontal stow position atop the seat base, wherein the seat base is pivotally connected to the floor such that, when the seatback is moved from its use position to the folded, stow position, the seat base may be moved rearward and downward to thereby provide a lower load floor position. The seat also includes a lock mechanism to engage and lock the seat base in a first position when the seatback is positioned within the defined range of use positions, and unlock the seat base for movement to a second position when the seatback is positioned outside the use range.

Abstract: A vehicle seat controller is provided to control a front seat assembly and a rear seat assembly positioned directly behind of the front seat assembly. The vehicle seat controller programmed to receive a first input indicating whether the rear seat assembly is occupied and receive a second input indicating a position of the front seat assembly. The vehicle seat controller is programmed to provide a signal to an actuator to move the front seat assembly forward if the first input indicates the rear seat is occupied and the second input indicates the position exceeds a rearward travel threshold.

Abstract: A back-drive speed control system for incorporation into an actuated vehicle seating system includes an actuator having a permanent magnet and a coil that can move relative to each other to create a voltage across a first terminal and a second terminal. The actuator is adapted to move a linkage in an actuated vehicle seating system. A biasing member moves one or both of the permanent magnet and the coil such that the first terminal has a positive potential relative to the second terminal. The back-drive speed control system further includes a first diode and a Zener diode in series connected across the first terminal and the second terminal such that the forward current direction of the first diode is oriented in the opposite direction to the forward current direction of the Zener diode.

Abstract: An actuator assembly for moving a vehicle seat on a track includes an actuation cable having a first end and a second end, an actuation gear unit having an output gear with a spool feature attached to the first end of the actuation cable, a first biasing member, and an actuator in communication with the actuation gear unit. The output gear rotates about a first axis, the actuation cable partially windable upon the spool feature. Characteristically, the actuator when actuated rotates the actuation gear unit to wind the actuation cable onto the spool feature thereby retracting the actuation cable from a first position to a second position. Advantageously, the first biasing member biases the actuation gear unit to move the actuation cable from the second position to the first position.

Abstract: A vehicle seat assembly and a method of controlling a vehicle seat assembly are provided. The vehicle seat assembly has a frame, and a seat pan extending from a forward region to a rearward region, with the rearward region of the seat pan rotatably connected to the frame. A torque tube is supported for rotation by the frame and extends transversely across the seat pan. At least one cam is supported by the torque tube for rotation therewith, and the at least one cam extends outwardly from the torque tube to an associated cam surface. The cam surface supports the forward region of the seat pan and is shaped such that the forward region of the seat pan is raised relative to the rearward region in response to rotation of the torque tube.
