    Abstract: An object of the present invention is to provide a compact base for a seat with a suspension for a vehicle driver, for use in buses, heavy vehicles or special use vehicles, including excavation vehicles or foresting equipment, in which the operator or driver is subject to vibrations. The present invention provides total independence of the suspension properties, including stiffness, damping and range of travel, with height adjustment. In order to accomplish this, the compact base for the seat is divided into parts including a suspension and a seat height adjustment mechanism. These parts have no common component including balloons, dampers or guiding systems. In this manner, the suspension properties of the seat are not affected by the seat height adjustment. Moreover, the invention provides a compact seat base through the use of structures and balloons that fit one within the other.

  • Patent number: 6270159
    Abstract: A manual uplift apparatus comprising a structural frame unit, a mechanical uplift assembly unit, and a power translating mechanism connecting the two units to allow the user to more easily obtain a standing position from a previously seated position. A second use for the apparatus may be as an exercise product for exercising upper body muscle groups. The structural frame unit is used to support and guide the mechanical uplift assembly unit. The mechanical uplift assembly unit has two sections that can independently move vertically with respect to the structural frame unit. One section has a seat, the other has rails or hand engagement handles. When downward force is applied to the hand engagement handles, the section having the handles move vertically downward and produces an upward force in the section having the seat through the power translating mechanism.

  • Patent number: 6224154
    Abstract: An operable chair includes a seat which is pivotally connected to a support arm, the support arm being operably mounted on an upright frame for selective vertical movement along the frame. The seat is mounted for selective and adjustable tilting so that an operator may lean forward from the chair at a desired angle. A footrest is operably mounted to the upright support for selective vertical movement there along, independent of the seat. The footrest includes a foot platform which is selectively pivotable as well. A body restraining harness is provided for an operator seated in the seat, and includes an adjustable length cable connected to a bracket operably mounted on the upright support, to adjustably restrain the upper torso of a person seated in the seat, with the upper torso leaning forwardly over a desired work site.
