A lawn maintenance vehicle includes an adjustable seat assembly, wherein the seat assembly is rotatable relative to a frame of the vehicle when the vehicle is operated on a sloped surface. The seat assembly is rotatable in order to maintain the operator in a substantially vertical seated alignment while operating the vehicle on a sloped surface. The seat assembly is also rotatable when the vehicle is in a zero-turn or tight-turn maneuver, wherein the seat is rotated toward the center of turning radius to offset the centrifugal forces experienced by the operator during such a maneuver.

Removable seats and lawnmowers with removable seats are provided. A lawnmower includes a frame; a walking element coupled to the frame to move the lawnmower relative to an underlying ground surface; and a seat selectively coupled to the frame, the seat including: one or more rails; a lower support adjustably coupled to the one or more rails; a backrest coupled to the lower support; and a latch coupled to the lower support through at least one of the one or more rails, the latch being selectively engageable with the frame to maintain the seat in a riding position, wherein the seat is removable from the frame by rotating the seat about a horizontal axis.

Vehicle seat having a pitching spring unit, a vehicle seat upper part and a vehicle seat lower part of the vehicle seat being connected such that they can be moved relative to one another by means of a scissor frame arrangement, comprising a first scissor arm and a second scissor arm which cross in a first region as viewed in a vehicle seat width direction, the pitching spring unit comprising a spring element carrier and a spring element, the spring element being connected on one side to the vehicle seat upper part, the vehicle seat lower part or the scissor arms and on the other side to the spring element carrier which is connected to the first scissor arm such that it can be rotated about a second rotational axis and to the second scissor arm such that it can be rotated about a third rotational axis.

Vehicle structure includes a front seat for a driver and a rear seat for a passenger aligned with each other. The front seat is slidable and/or tiltable between a rearward position, in which it is rigidly secured to the frame of the rear seat by a releasable locking device, and a forward position, in which a gap is formed between the front seat and the rear seat to facilitate the access and exit of the passenger.

An operator workplace for a construction machine, comprising a driver seat with a seating surface, an armrest arranged next to the seating surface and having an arm support surface and a control wheel for controlling at least one machine function, the control wheel being rotatable about a control axis, the control axis of the control wheel being tilted relative to a vertical line by a tilt angle in a direction toward the arm support surface of the armrest. Moreover, the invention relates to a construction machine, in particular a ground compaction machine, for example a road roller or single-drum roller, or a road paver, having such an operator workplace.

The present disclosure describes vehicle seats having integral components for use with ventilation, air conditioning, and/or heating systems. Air ducting can be incorporated into the seat base and the seat back. Further, air can be directed through a rear-facing outlet vent in the seat back, providing improved ventilation, air conditioning, and/or heating for rear passengers of a vehicle.
