An electro-mechanical seat swivel system may include a bottom plate mounted on a frame of a machine or vehicle, and top plate pivotally mounted on the bottom plate, and an operator seat mounted on the top plate. A pawl may be movably mounted on the bottom plate and engage latch catch brackets mounted to the top plate to lock the seat in predetermined operator seat positions. An electro-mechanical actuator may be mounted to the seat and operatively coupled to the pawl. Latch control switches disposed at operator controls may be operated to cause the electro-mechanical actuator to disengage from one of the latch catch bracket to allow the seat to be rotated to another of the predetermined operator seat positions where the pawl will engage the corresponding latch catch bracket to again lock the operator seat in place.

Electro-mechanical seat swivel system

A suspension system for a seat assembly of a machine includes an upper support member and a lower support member. A pair of scissors linkages interconnect the upper and lower support members. Each of the scissors linkages includes first and second arms pivotably attached at central portions thereof. An electronic controller is in communication with a pair of electromagnetic devices positioned at first ends of the first arms. The electronic controller is configured to energize the electromagnetic devices in response to a sensor output.

A scissor suspension includes a first arm having a first end and a second end. The first end may be configured for pivotal attachment to a structure and a first bearing may be pivotally connected proximate to the second end of the first arm. A second arm having a first end and a second end may be pivotally connected to the first arm between the first and second ends of the first and second arms. The first bearing may be moveably coupled to the first rail.

Scissor suspension

An adjustable control pedestal for a work machine. The control pedestal may include a base configured to be rigidly mounted to a chassis of the work machine. The control pedestal may also include an armrest portion having a joystick mounted thereto configured to control at least one function of the work machine, the armrest portion being connected to the base and configured to enable an operator to rest an arm on the armrest portion while operating the joystick. The armrest portion may be linearly movable relative to the base.
