Swivel mechanism for vehicle seat

摘要

A vehicle passenger seat swivel mechanism connected between a seat frame and a seat base secured to a vehicle body. The swivel assembly can include a swivel axis around which the seat frame rotates and a tracking axis, approximately perpendicular to the swivel axis, along which the seat frame can translate. A guide plate can be disposed on the seat base and has a guide plate rail. A guide follower can be disposed on the seat frame having an engagement surface engaging the guide plate rail. As the seat frame swivels around the swivel axis, the guide follower is displaced along the translation axis, which causes at least the seat frame to displace in the same direction along the translation axis, to at least a first or a second clearance distance from the swivel axis, and the guide plate and the guide follower do not overlap along the swivel axis.
