Patent number: 10495211Abstract: A shifter assembly including a shift lever pivotally mounted to a housing, a shift lever, a first pivot mechanism, a gimbal ring, and a second pivot mechanism. The lever is movable in a first gate along a first plurality of paths, a second gate along a second plurality of paths, and a bridge gate between the first and second gates. The first pivot mechanism is mounted to the lever to permit movement about a first pivot axis within one of the gates. The gimbal has an aperture and is disposed about and coupled to the lever. The second pivot mechanism is mounted to the gimbal to permit movement about a second pivot axis within another one of the gates. The axes are spaced from each other. The gimbal has receivers recessed from the inner surface with the first pivot mechanism engaging the receivers to couple the lever to the gimbal.Type: GrantFiled: September 8, 2014Date of Patent: December 3, 2019Assignee: Kongsberg Automotive ABInventors: Anders Kvarnström, Bengt Cyrén
