Abstract
A window regulator including a drive rod having a linear axis; a runner connected to the drive rod for movement therealong; a window carrier pivotally secured to the runner for supporting a window; and a guide engaged by the window carrier having a radius of curvature such that the window carrier moves the window along a path coincident with the radius of curvature as the runner moves linearly along the drive rod.
Claims8
An automotive window regulator system comprising:
- a guide rod defining a central axis extending in a vertical direction, said guide rod adapted for rotating about said central axis;
- a runner including a body portion and a pair of trunnions, said runner drivingly engaged with said guide rod, said runner moveable in said vertical direction along said guide rod between a first position and a second position in response to rotation of said guide rod;
- and
- a window carrier including a primary channel extending in said vertical direction and a secondary channel extending in a lateral direction substantially orthogonal to said vertical direction, said body portion of said runner is disposed in said primary channel which prevents rotation of said runner about said central axis and said trunnions are disposed in said secondary channel thereby coupling said runner and said carrier together for movement of said carrier with said runner in said vertical direction, said trunnions defining a lateral axis substantially orthogonal to said central axis;
- wherein said carrier rotates about said lateral axis and said carrier translates in a horizontal direction substantially orthogonal to said vertical and lateral directions such that said trunnions move relative to said carrier in said horizontal direction within said secondary channel in response to moving said runner between said first and second positions, whereby a rotational and translational movement of said carrier permits nonparallel movement of said carrier with respect to said central axis as said runner moves between said first and second positions.

- an arcuate window mounted to said carrier, said window having a radius of curvature;
- and
- a guide engaging said carrier, said guide having substantially the same radius of curvature as said window such that said carrier guides said window along a path coincident with the radius of curvature of said window as said runner moves between said first and second positions.
