Embodiments related to active vibration isolation systems for a vehicle seat, as well as their methods of use, are disclosed. In some embodiments, an active suspension system may be configured to support a seat above a floor of a vehicle. The active suspension system may include two or more actuators that may be operated cooperatively to control both the roll and heave of the vehicle seat. In someinstances, these actuators may also be non-back-drivable actuators. Additionally, in some embodiments, an active suspension system may include one or more torsion springs that apply torques in parallel with associated actuators of the active suspension system to support at least a portion of the loads applied to the active suspension system during operation.
公开了涉及用于车辆座椅的主动式振动隔离系统以及主动式振动隔离系统的使用的方法的各实施方式。在一些实施方式中,主动式悬架系统可以构造成将座椅支承在车辆的地板上方。主动式悬架系统可以包括两个或更多个致动器,所述两个或更多个致动器可以被协同操作以控制车辆座椅的侧倾和起伏两者。在一些情况下,这些致动器还可以是不可反向驱动的致动器。另外,在一些实施方式中,主动式悬架系统可以包括一个或更多个扭力弹簧,所述一个或更多个扭力弹簧以平行于主动式悬架系统的相关联的致动器的方式施加扭矩,从而在操作期间对施加至主动式悬架系统的载荷的至少一部分进行支承。
