Abstract: A compressive member is used to bias a seat backrest into a predetermined position, generally upright as illustrated, relative to a seat base with the compressive member deforming to enable the seat to be pivoted by the application of force to the backrest. When used on a materials handling vehicle for which it is particularly applicable, the resiliently biased backrest attenuates forces that are transferred to the back of an operator occupying the seat when the vehicle is driven over irregularities in a floor supporting the vehicle.

Abstract: An operator's compartment for an industrial vehicle comprises a platform floor, an operator's seat, at least one presence sensing device and a control module. The operator's seat has a base structure coupled to the platform floor and an operator support coupled to the base structure such that the operator support may be rotated with respect to the platform floor. Each provided presence sensing device is arranged to sense an operator's presence in a predetermined location in or about the operator's compartment and the control module is configured to control at least one operation of the vehicle based upon a rotational position of the operator's seat and a signal from at least one of the presence sensing device(s).

Abstract: Seat repositioning systems for vehicles comprise an operator's seat having a seat bottom and optionally, a seat back, where the operator's seat further comprises an adjustable characteristic, such as seat rotation, seat height adjustment, tilt, or X-Y position. A seat release control is operable to release the operator's seat from a locked position for repositioning of the adjustable characteristic of the operator's seat.

Abstract: A vehicle seat arrangement is provided for a working vehicle comprising an operator's seat having an adjustable feature. A first control element is arranged such that a first work operative position is defined. A seat adjusting element is further provided for enabling the operator to set the adjustable feature of the operator's seat. The seat adjusting element is positioned relative to the first control element such that the operator may selectively control the adjustable feature of the seat without significantly interrupting the first work operative position or without significantly interrupting a transition from a first task to a second task and/or from a first work operative position to a second work operative position.

Abstract: Seat repositioning systems for vehicles comprise a seat release element that is operable to cause an operator's seat to be temporarily released from a locked position such that the operator's seat may be adjusted to a new position. By optionally positioning the seat control element proximate to an operator's working position, a vehicle operator may reposition the seat while simultaneously performing another task. Moreover, a controller may be provided that is capable of deciding whether or not to allow the operator's seat to be released based upon vehicle parameters such as vehicle speed or load handling conditions. Still further, the controller may temporarily disable select features of the vehicle depending upon the position of the seat.

Abstract: An operator's seat for a vehicle includes a base structure that allows the operator's seat to be rotated with respect to a platform floor of an operator's compartment within the vehicle. The operator's seat may further include a swivel structure that allows an operator support to swivel independently of the rotation of the base structure. At least one presence sensing device may be provided to detect the presence of an operator. The presence sensing device(s), and rotational position of the operator support may provide input signals to a control module that controls the vehicle travel, load handling features, and/or other features of the vehicle that may be selectively enabled, limited or otherwise controlled.
