A seat suspension includes a seat support, a base, and a suspension assembly positioned between the seat support and the base. The suspension assembly includes a compressible cushion for containing a gas; and a chamber. The chamber includes a cylindrical hollow member, a front cap at one end of the cylindrical hollow member, an end cap at another end of the cylindrical hollow member, and a piston positioned within the cylindrical hollow member between the front cap and the end cap. The front cap includes an orifice. The orifice provides fluid communication between the cushion and the chamber. When a compressive force causes movement of the seat support portion towards the base, thereby compressing the cushion, the gas from the cushion flows through the orifice into the chamber and directly forces movement of the piston away from the front cap.

A ride height adjustable oil damped air shock boat seat pedestal with selectively lockable swivel capability is shown, which includes a locking pin extending below the seat and moving up and down with the seat as permitted and controlled by the air shock. The locking pin being received by a structure, which limits rotation of the seat.

There are improved a vibration absorption characteristic and an impact absorption characteristic. A seat suspension mechanism set so that links of a first link mechanism on a base frame side and links of a second link mechanism on a seat support frame side, between which an intermediate frame is put, differ in operating angles, that is, so that the links of the second link mechanism operate in the range of an angle closer to a vertical to a front-rear direction of a vehicle body. This allows front-rear movement of the seat support frame through the second link mechanism to mainly respond to input vibrations of front-rear movement to thereby improve a vibration absorption characteristic and an impact absorption characteristic in the front-rear direction.

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 vehicle seat having a suspension unit for cushioning the rolling and vertical suspension movements of the vehicle seat, wherein the vehicle seat has a vehicle seat upper part and a vehicle seat lower part, wherein the vehicle seat upper part and the vehicle seat upper part are connected by means of the suspension unit so that the vehicle seat upper part and the vehicle seat lower part are movable relative to one another, wherein the suspension unit has a scissor arrangement having a first scissor arm and a second scissor arm, the suspension unit is rotatably connected about a first axis of rotation to the vehicle seat lower part and comprises a spring element support and a first spring element, wherein a displacement element is provided which is mounted displaceably with respect to the vehicle seat lower part, wherein the first spring element is connected on the one hand to the displacement element and on the other hand to the spring element support, which is rotatably connected about a second axis of rotation to the first scissor arm and rotatably connected about a third axis of rotation to the second scissor arm.

An adjustable suspended seat apparatus having a tuned frequency-tailored damping through stratified seat structure is described. The damping seat structure includes: a first material of a plurality of materials having a first characteristic to provide a first damping effect in a first layer. A second material of the plurality of materials based on a second characteristic to provide a second damping effect in a second layer, the first material or the second material having an adjustable damping characteristic. The suspended seat apparatus includes a seat base configured to have the seat coupled thereto; a suspension system coupled to the seat base, the suspension system comprising: an adjustment feature configured to adjust operation of the suspension system; and a chassis mount coupled to the suspension system, the chassis mount configured to be coupled to a vehicle.

A seat air bladder assembly is provided with at least one central air bladder region having a support surface. At least one pair of lateral air bladder regions extend from opposed sides of the at least one central bladder region. The at least one pair of lateral air bladder regions are oriented at a non-zero angle to incline laterally and support a thoracic region of a seat occupant. A seat assembly is provided with a seat back with a contact surface with a thoracic region. An air bladder assembly is oriented within the thoracic region of the seat back with a support surface that is reclined relative to the contact surface to provide support, and wedge-shaped so that during inflation the air bladder assembly inflates in an upward and forward direction relative to the seat back.

A seat position adjuster with a manipulable control shaft carrying a position locking latch and a spring that biases the latch toward a latched position that locks seat position with the spring being part of a vibration isolator selectively deactivated by an isolator lockout. The shaft is rotatively and axially movable relative to a mounting bracket carrying the shaft that also is attached to one rail of a slide mechanism with the latch being urged by spring into operative engagement with the other rail. Spring is captured in torsion rotatively biasing the latch toward the latched position and is active in tension and/or compression isolating the seat from vibration and lateral/longitudinal accelerations. A control shaft of the lockout is manipulable between a locked position deactivating isolation by preventing axial movement of the position adjuster control shaft relative to bracket and an unlocked position permitting relative axial movement therebetween activating isolation.

There is described a vehicle seat suspension mechanism, comprising a vehicle mount, a seat support linked to the vehicle mount by a suspension arrangement which allows the seat support to fall with respect to the vehicle mount under load and a shock strut arranged to resist the seat support falling with respect to the vehicle mount during a compression stroke. A control link is arranged to be driven about a control link pivot by the fall of the seat support. The control link is pivotally coupled to a first end of the shock strut to guide the first end with respect to a second end of the shock strut in a manner which causes a motion ratio of the suspension mechanism to increase during progression of the compression stroke. The ride will feel softer for smaller impacts and better damped later for larger impacts. The mechanism is arranged underneath a seat of a vehicle to provide additional comfort for the rider.

The invention relates to a horizontal vibration device for a vehicle seat, comprising a damper module which damps horizontal vibrations between a seat-side upper part and a body-side lower part in the longitudinal direction of the vehicle and/or in the width direction of the vehicle, and comprising a regulating/control module for regulating and/or controlling the damper module, said damper module being arranged in an interspace between the seat-side upper part and the body-side lower part. The horizontal vibration device is further characterized in that the damper module comprises at least one hydraulic vibration damper, said at least one hydraulic vibration damper being fluidically connected to a volume equalizing module.
