Abstract

The invention relates to a seat adjuster drive for a vehicle. The seat adjuster drive including a stationary track that is fixed to a vehicle and a sliding track that is arranged in sliding engagementwith the stationary track for movement fore and aft. A gear box, mounted to the sliding track, supports a pinion that is part of a rack and pinion drive assembly. The gear box houses a conical spiralgear set and one or more planetary gear sets. The conical spiral gear set includes a conical pinion gear that is coupled to an electric motor and a conical spiral gear that is arranged in meshing engagement with the conical pinion gear. The conical spiral gear is carried on the pinion in a sliding fit. The one or more planetary gear sets rotatably couple the conical spiral gear and the pinion through a gear reduction.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 807,983, filed February 20, 2019. The entire disclosure of the above application is incorporated herein by reference. technical field [0003] The present disclosure generally relates to automotive seat adjuster drives. More specifically, a rack and pinion automotive seat adjuster drive is disclosed. Background technique [0004] This section provides background information related to the present disclosure which is not necessarily prior art. [0005] In today's vehicles, the number of electric actuators is increasing. By way of example and not limitation, electric actuators are commonly used to power vehicle seats and provide various modes of seat adjustment. Electric actuators are driven by electric motors that are sized for the torque they must provide to produce the desired motion. Therefore, if a reasonably high reduction ratio is avai...
