A kinetic seat assembly includes a primary seat cushion frame, a secondary seat cushion frame movable relative to the primary seat cushion frame, a primary seat back frame, a secondary seat back frame movable relative to the primary seat back frame, a pair of lateral dampers extending between the primary seat back frame and the secondary seat back frame, a pair of vertical dampers extending between the secondary seat back frame and the primary seat cushion frame, a pair of fluid reservoirs for providing a fluid into the pair of lateral dampers and the pair of vertical dampers, and an electronic control unit configured to control the rate at which the fluid is provided to and drawn out of each of the dampers to control a damping effect. In embodiments, an end of the lateral dampers is permitted to move freely relative to the secondary seat back frame.

An operator seat of a work vehicle includes a seat base, a support, a flange, and a suspension apparatus. The seat base has a base frame. The support extends upward from a rearward portion of the seat base. The backrest is rotatably coupled to the seat base with the support and reclinable relative to the seat base. The flange is coupled to the support and rotatable relative to the support around a first axis. The suspension apparatus is coupled between the flange and the backrest to provide rotation between the flange and the backrest around the first axis. The rotation of the flange rotates the suspension apparatus.

The present shock absorbing structure of an ATV seat for an ATV with a vehicle frame and a seat frame, comprising an elastic support member provided between the seat frame and the vehicle frame, the elastic support member supporting the seat frame and allowing the seat frame to move downward and compress the elastic support member when subjected to an external force. The shock absorbing structure further comprises at least one shock absorber block provided between the seat frame and the vehicle frame, the at least one shock absorber block being either attached to the seat frame and having a gap in an up-and-down direction from the vehicle frame, or attached to the vehicle frame and having a gap in the up-and-down direction from the seat frame. The present shock absorbing structure of an ATV seat provides overall enhanced comfort.

A kinetic seat assembly including a primary seat cushion frame including a rear rod extending between opposite rails, a secondary seat back frame movable relative to the primary seat cushion frame, a pair of clamps provided on the rear rod of the primary seat cushion frame, and a pair of vertical dampers coupled between the secondary seat back frame and the pair of clamps on the primary seat cushion frame, each clamp receiving an end of a corresponding vertical damper. In embodiments, the vertical dampers are arranged in a V-shape such that the vertical dampers are oriented at an angle relative to one another such that a distance between a first end of each vertical damper is greater than a distance between a second end of each vertical damper.

A passenger restraint system for roller coasters designed to maintain a passenger in an essentially seated or lying posture, with suspended feet. The passenger restraint system includes a fixed column and a seat column designed to support and hold the passenger, which seat column is coupled to the fixed column so as to be displaceable with respect to the fixed column during a roller coaster ride. The seat column is coupled to the fixed column by an articulated linkage, and the passenger restraint system further includes a balancing device ensuring a balancing of the seat column, which balancing device is fixed, at a first end, to the fixed column and, at a second end, to the seat column. The balancing device can advantageously be configured to ensure a vertical travel of the seat column during the roller coaster ride in dependence of a vertical acceleration exerted on the passenger.
