Abstract: A single-stage gear reduction output mechanism for an automotive seat assembly including a gear housing bracket, gear housing, axle shaft, eccentric, and first and second gears. The axle shaft extends through the eccentric with a slip fit, the first gear rotates with the axle shaft, and the second gear is carried on a first bearing surface of the eccentric and meshingly engages the first gear in a planetary arrangement. A locking plate including first, second, and third slot cutouts is disposed within the gear housing. A support pin extends from the gear housing through the first slot cutout and a second bearing surface of the eccentric extends through the second slot cutout to support the locking plate and limit its movement along a lateral axis. The second gear includes a first pin that extends through the third slot cutout to prevent the first gear from back-driving the second gear.

The axle shaft extends through the eccentric with a slip fit, the first gear rotates with the axle shaft, and the second gear is carried on a first bearing surface of the eccentric and meshingly engages the first gear in a planetary arrangement. The second gear includes an external flange with at least two guide holes. First and second support pins that are rigidly fixed in place relative to the axle shaft extend through the two guide holes in the external flange of the second gear. Forces acting at the interfaces between the first and second support pins and the two guide holes and between the eccentric and the second gear prevent the first gear from back-driving rotation of the second gear.

Abstract: A seat adjuster assembly for a vehicle seat assembly may include a housing, a worm, a spindle screw, a motor, and either a helical gear or a single-enveloping worm gear. The worm may be disposed within the housing for rotation about a first axis and having a thread. The helical gear or single-enveloping worm gear may be disposed within the housing for rotation about a second axis and meshingly-engaged with a pitch surface of the thread of the worm. The spindle screw may extend along the second axis and through the housing and the helical gear or single-enveloping worm gear. The spindle screw may be meshingly-engaged with the helical gear or single-enveloping worm gear. The motor may drive the worm to cause linear movement of the housing, worm, motor, and the helical gear or single-enveloping worm gear along the second axis.

Abstract: 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.

Abstract: A seat adjustment assembly includes a housing, a worm, a gear, and a rail. The worm is disposed within the housing for rotation about a first axis and including a helical thread defining an arcuate profile extending about the first axis. The gear is disposed within the housing for rotation about a second axis and is meshingly-engaged with the worm. The rail extends through the housing and the gear for rotation about a third axis. The rail is meshingly-engaged with the gear.

CPC classification number: B60N2/067 , B60N2/0825
Abstract: 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.

Abstract: A vehicle seat adjustment mechanism may include a gearbox, a first gear, a second gear, and a spindle screw. The first gear is received in the gearbox and is rotatable relative to the gearbox about a first axis. The second gear is received in the gearbox and is rotatable relative to the gearbox about a second axis that is perpendicular to the first axis. The first and second gears are meshingly engaged with each other. The spindle screw is meshingly engaged with the second gear and extends through the second gear along the second axis. The spindle screw may have trapezoidal threads.
