Abstract
A power seat track assembly may include an elongated first rail, a second rail, a motor assembly, and a power-transfer assembly. The second rail may engage the first rail and may be movable along a length of the first rail. The motor assembly may be mounted to the second rail and may be operable to drive the second rail along the length of the first rail. The power-transfer assembly may include a first component mounted to the first rail and a second component mounted to the second rail. The first component may wirelessly transmit power to the second component. The second component may be electrically connected to the motor assembly to provide electrical current to the motor assembly.
Claims16
A vehicle seat assembly comprising:
- a vehicle seat;
- an elongated first rail mounted to a vehicle cabin floor;
- a second rail engaging the first rail and movable along a length of the first rail;
- a motor assembly mounted to the second rail and operable to drive the second rail along the length of the first rail;
- and
- a power-transfer assembly including a first component mounted to the first rail and a second component mounted to the second rail, wherein the first component wirelessly transmits power to the second component, and wherein the second component is electrically connected to the motor assembly to provide electrical current to the motor assembly,
- wherein the first rail is fixed relative to the vehicle cabin floor, and wherein the second rail supports the vehicle seat for movement relative to the first rail and the vehicle cabin floor,
- wherein the motor assembly includes a pinion that is rotatable about a rotational axis, and wherein a rack is fixed to the first rail and includes a plurality of teeth that meshingly engage the pinion,
- wherein the rack includes a first aperture, wherein the first rail includes a second aperture, and wherein a fastener extends through the first and second apertures and into a third aperture in the vehicle cabin floor, and
- wherein the teeth of the rack are formed on a lateral surface of the rack, and wherein the rotational axis of the pinion is parallel to a longitudinal axis of the fastener.
