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.
