A seat track system for a seat of a vehicle includes at least one seat track having a lower track member adapted to be fixed to a vehicle structure and an upper track member adapted to be connected to a seat and moveable relative to the lower track member. The seat track system also includes a manual positive engagement locking system cooperating with the at least one seat track to allow longitudinal adjustment of the upper track member relative to the lower track member and to positively engage the at least one seat track such that a locking element does extend through the locking plate but does not extend below the lower track member.

A double involute pinion-face gear drive system provides transmission of torque and speed, or direction of movement modification between non-intersecting shafts at right angles to one another. Specifically, the system includes three distinct types of gear drives, in which a double involute cylindrical pinion mounted on one of the two axes, engages a rotatable disk-shaped gear mounted on the second axis, disposed orthogonally offset at a prescribed center distance relative to the first axis. The teeth of the cylindrical pinion are curved in an abridged, normal or extended involute shape and may include an involute-shaped tooth depth profile in a plane passing through the tooth pitch point and orthogonal to the axis of the pinion. Likewise, the teeth of the face gear are curved in abridged, normal or extended involute shape in the lengthwise direction of the teeth and may include a straight line shaped tooth depth profile. These gear drive systems can be simultaneously bi-rotational and bi-directional. The novel gear drive system allows for a relatively wide range of low gear speed ratios, as low as 1:1 and as high as 7.5:1, in a compact arrangement.

A gearbox for a vehicle seat adjustment mechanism in accordance with the principles of the present disclosure includes first and second portions. The first portion includes a first body defining a first longitudinal recess and a first peripheral recess in fluid communication with the first longitudinal recess. The first body includes a concave first curved surface. The second portion includes a second body defining a second longitudinal recess and a second peripheral recess in fluid communication with the second longitudinal recess. The second body includes a convex second curved surface. The second curved surface has an equal and opposite curvature compared to the first curved surface. In an assembled configuration, the first and second curved surfaces are in contact, the first longitudinal and second longitudinal recesses cooperate to define a longitudinal passage, and the first and second peripheral recesses communicate to define a peripheral receptacle.

A recliner mechanism includes first, second and third locking plates and a fastener. The first locking plate has a first inner diametrical surface having first teeth formed thereon. The second locking plate has a second inner diametrical surface having second teeth formed thereon. One or both of the first and second locking plates may include an aperture extending therethrough. The third locking plate has an outer diametrical surface having third teeth formed thereon. Some of the third teeth are meshingly engaged with some of the first teeth and some of the second teeth. The fastener may extend through the aperture and is attached to one of a seatback and a seat bottom.

A method of manufacturing a gear drive for a seat adjuster assembly may include applying a cutting process to a worm gear blank to cut gear teeth into the worm gear blank and form a single-enveloping worm gear; forming a worm with a helical thread that includes a pitch surface that is configured to mesh with the gear teeth of the single-enveloping worm gear. A longitudinal crown is created on the pitch surface of the helical thread of the worm such that the pitch surface has an arcuate profile moving from a proximal end of the worm to a distal end of the worm. In addition, a crowned tooth profile is created on the helical thread of the worm that extends in an angular direction between a top land and a bottom land of the helical thread. The crowned tooth profile bows outwardly along a convex curve.

A seat adjuster drive including a stationary track that is fixed to a vehicle and a sliding track that is arranged in sliding engagement with 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 spiral gear 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.
