Abstract
A vehicle seat adjustment mechanism includes a first component and a second component that is movable relative to the first component. A drive mechanism is drivingly connected to the second component for moving the second component relative to the first component. The drive mechanism includes a drive motor drivingly connected to a first gear member having conical involute teeth. A second gear member includes conical involute teeth in meshing engagement with the conical involute teeth of the first gear member. The conical involute teeth have a tapered tooth thickness, a tapered root and a tapered outside diameter.
Claims20
A vehicle seat adjustment mechanism, comprising:
- a first component;
- a second component movable relative to the first component;
- a drive mechanism drivingly connected to the second component for moving the second component relative to the first component, the drive mechanism including a first gear member and a second gear member, wherein the first gear member is drivingly connected to a drive motor, and wherein the second gear member is in meshing engagement with the first gear member, wherein the drive mechanism includes a gear reduction mechanism providing a driving connection between the drive motor and the first gear member;
- and
- a washer that is resiliently deformable and allows adjustment of the first gear member relative to the second gear member,
- wherein the gear reduction mechanism includes a housing and an eccentric disposed within the housing,
- wherein the eccentric is rotatably connected to the drive motor and a locking plate that engages the eccentric and one of a planetary gear and a ring gear and the other of the planetary gear and the ring gear is drivingly connected to the first gear member, and
- wherein the planetary gear includes exterior conical involute teeth and the ring gear includes interior conical involute teeth.
A vehicle seat adjustment mechanism, comprising:
- a first component;
- a second component movable relative to the first component;
- a drive mechanism drivingly connected to the second component for moving the second component relative to the first component, the drive mechanism including a first gear member having conical involute teeth, the first gear member drivingly connected to a drive motor, a second gear member having conical involute teeth in meshing engagement with the conical involute teeth of the first gear member;
- and
- wherein the drive mechanism includes a gear reduction mechanism providing a driving connection between the drive motor and the first gear member,
- wherein the gear reduction mechanism includes a housing and an eccentric disposed within the housing, wherein the drive motor is attached to the housing, and
- wherein the eccentric is rotatably connected to the drive motor and engaged with a wobbling planetary gear with exterior conical involute teeth that engage interior conical involute teeth of a ring gear that is drivingly connected to the first gear member, the wobbling planetary gear including a locking plate with at least two guiding holes that each receive a respective cylindrical pin mounted to a housing of the gear reduction mechanism.
