摘要： A seat support includes first and second link members coupling a seat supporting member to a base. The second link member has a first end portion pivoted to the base at a first pivot axis and a second end portion pivoted to the seat supporting member at a second pivot axis. The first link member has a first end portion pivoted to the base at a third pivot axis and a second end portion pivoted to the seat supporting member at a fourth pivot axis. The distance between the third and fourth pivot axes is greater than the distance between the first and second pivot axes and may be from about twelve percent to about twenty percent greater. The location of the pivot axes may be expressed by the formula L

摘要： A seat suspension system includes a vibration dampener adapted to operate over less than the full range over which a seat may be raised and lowered by a seat height adjuster, such as an air spring. The dampener may apply dampening forces which vary non-linearly, depending upon the extent a seat moves as a result of seat vibration. In several specific forms, the dampening mechanism is unlatched to permit relative movement of the seat and seat support mechanism relative to the dampener during seat height adjustment, with the dampener being relatched to again apply a dampening force. A mechanically simply seat leveling system may be employed to return the seat to a desired elevation in the event loading on the seat is varied, for example if a seat occupant gets up off a seat.

摘要： A seat suspension method in one approach involves applying a dampening force over less than the full range over which a seat may be raised and lowered by a seat height adjuster. The step of applying a dampening force may comprise applying such a force which varies non-linearly, depending upon the extent a seat moves as a result of seat vibration. In several specific approaches, unlatching of the dampening mechanism may be accomplished to permit relative movement of the seat and seat support mechanism during seat height adjustment. Relatching of the vibration damper may be accomplished to again apply a dampening force. The seat may automatically be returned toward a desired elevation in the event loading on the seat is varied, for example if a seat occupant leaves the seat.

摘要： A coupler, such as a piston pin, is pivotally coupled to a piston such that the piston can pivot about a first axis relative to the coupler. A connecting rod is coupled to the coupler for pivoting about a second axis. The relative positions of the first and second axes can be shifted by pivoting an eccentric portion of the coupler to thereby vary the compression ratio of a piston cylinder within which the piston slides. The coupler comprises a pivot member engager portion that is selectively shifted from first to second positions to vary the compression rates in response to shifting of a pivot member. The pivot member engager is shifted from first to second positions as the piston approaches the bottom dead center position. The pivot member and pivot member engager disengage from one another as the piston travels away from the bottom dead center position.

摘要： A vehicle axle construction comprises a suspension for supporting the axle from first and second frame rail members. Elongated support members extend forwardly from respective locations along the frame rail members that are rearwardly of the axle and are clamped or otherwise coupled to the axle. A single pivot may be utilized to couple the respective rearmost end portions of the supports to the respective frame members. The forward ends of the supports may be coupled to respective air springs. Desirably, at least a portion of each air spring is positioned forwardly of the axle. In addition, at least one lateral stabilizer rigidifies the suspension. An alternative suspension utilizes leaf springs. A double acting rack-and-pinion steering mechanism may be rigidly coupled to the axle for use in steering the wheels of the vehicle.

摘要： The compression ratio of an internal combustion engine is adjustable in a stepwise fashion, such as by pivoting an extension of an eccentric connecting rod bearing. The projection extends into a chamber defined by a portion of a connecting rod coupling portion of a connecting rod assembly. Liquid is delivered to one side of the projection and removed from the opposite side of the projection to move the projection and thereby the eccentric connecting rod bearing from one position corresponding to one compression ratio to another position corresponding to another compression ratio.

摘要： Mechanisms are described for selectively closing grille and/or bumper openings. These mechanisms may be operated in response to one or more vehicle parameters. Closure mechanism control signals may be delivered to such mechanisms along a vehicle databus. In addition, vehicle parameters used in determining the control of such mechanisms may be sensed and provided along the databus to a controller which then processes the parameter information for determining whether to open or close the vehicle grille closing mechanism and/or the vehicle bumper opening closing mechanism.

摘要： The parking brakes on a truck or other vehicle having plural axles are applied such that at least one wheel at a first end of a first axle receives a parking brake force without applying a parking brake force to any wheel at the opposite end of the first axle. In addition, at least one wheel at a second end of a second axle, the second end of the second axle being opposite to the first end of the first axle, receives a parking brake force. Desirably, any wheels at the opposite end of the second axle from the second end of the second axle are not the recipient of a parking brake force such that diagonally disposed parking brake forces are applied upon activation of the vehicle parking brakes. The first axle in one example is forwardly of the second axle and the first end of the first axle may be at the longitudinal side of the vehicle which is the heaviest.

摘要： A retractable stairway assembly for entering and exiting a vehicle with a cab has a stairway with steps. The stairway assembly is movable between a retracted position, in which the stairway is beneath the cab, and an extended position, in which the stairway is exposed to allow entering and exiting of the vehicle. The stairway assembly also has a panel that substantially hides the stairway when in the retracted position. An actuator moves the stairway assembly between the retracted and extended positions in response to closing and opening the door.
