A damper is provided on an upper frame which is a main vibrating body supported on upper portions of front links and rear links of a frame link mechanism, so as to be a sub-vibrating body which generates vibration whose behavior is different from that of vibration of the upper frame caused by the rotary motion of the front links and the rear links. When the upper frame is vibrated by input vibration, since the damper exhibits the different vibration behavior, energy of the input vibration not only is distributed as vibrational energy of the upper frame and heat energy generated by the elongation and contraction of the damper but also is consumed as energy which vibrates the damper itself provided as the vibrating body. Such arrangement and configuration of the damper improve basic performance of vibration absorbency and impact absorbency of the suspension and achieves a reduction in thickness.

A seat suspension system that includes a seat base that enables movement of the seat horizontally; and a lateral attenuation system that when activated, dampens movement of the seat horizontally. The seat base can move along first and second horizontal axes that are orthogonal. The seat base can include a carrier casting moveable along the first horizontal axis relative to a reservoir casting, and a seat casting moveable along the second horizontal axis relative to the carrier casting. The castings can move on rails. The lateral attenuation system can include an actuation mechanism, a stopper, and a connector that couples the actuation mechanism and stopper to the seat base. When the actuation mechanism is activated, the stopper can connect the reservoir and seat castings. The lateral attenuation system can be configured to stop movement of the seat along the first and second horizontal axes at any desired position.

A track assembly includes a track, a support member, and/or a lever. The support member may be connected to the track, and/or the lever may be connected to the support member. The lever may include a rotational axis substantially parallel to the track. The lever may rotate about the rotational axis between a first position and a second position. The lever may limit movement of the support member relative to the track in a first direction, and/or the lever may not limit movement of the support member relative to the track in a second direction. The lever may be configured to contact the track. The track may include a window having a first edge and/or a second edge.

A device for adjusting a seat of a vehicle is capable of implementing functions including adjusting a position of the seat back and forth, a height of the seat up and down, and tilting or the like by using a plurality of actuators having pistons. The functions of adjusting the position of the seat back and forth, the height of the seat up and down, and tilting or the like are carried out by providing connections between a floor panel and a seat cushion frame through a plurality of actuators and a single link, and selectively moving a piston of each actuator back and forth.

The invention relates to a suspension system (1), preferably a driver seat (1), comprising a first suspension part (10), preferably a frame (10) of the driver seat (1); a second suspension part (11), preferably a seat surface (11) of the driver seat (1), wherein the two suspension parts (10, 11) are movable relative to each other in at least one first spatial direction (Z), preferably in the vertical direction (Z); a kinematic system (12), preferably a scissor kinematic system (12) which is designed to connect the two suspension parts (10, 11) in a movable manner relative to each other at least in the first spatial direction (Z); a suspension device (13) which is designed to support the static load of the second suspension part (11); and an actuator (2) which is designed to introduce a force bidirectionally between the two suspension parts (10, 11) and thereby actively damp the relative movement between the two suspension parts (10, 11). The suspension system (1) is characterized in that the actuator (2) has a bearing (28), preferably a ball bearing (28), which is arranged within the power flow between the two suspension parts (10, 11) such that an axial load can be kept away from the driven axle of the actuator (2) at least partly, preferably completely.

A seating assembly for a vehicle includes a seat base pivotally and slidably coupled with a seatback and a support frame operable between a deployed position and a collapsed position. The support frame includes a first member that is pivotally coupled with a bottom portion of the seat base and pivotally coupled to a lower frame member fixedly attached to a floor support and a second member that is slidably coupled with a bottom portion of the seat base, pivotally coupled with the first member, and slidably coupled with the floor support. The support frame also includes a kickstand pivotally coupled to the floor support and slidably coupled to the seat base. The kickstand is operable between a forward position and a rearward position, wherein the kickstand is biased to and lockable in the forward position.

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 disclosed herein comprises a vehicle having improved suspension systems for wheels, motorized wheels and the seat of the user. The wheel suspension system includes a sleeve housing a non-round core snugly surrounded by an elastomeric shock-absorption material. Since both ends of the sleeve have downstanding arms forming the forks supporting a caster axle, irregularities in the terrain encountered by the caster exert torsion upon the core; embedding the core in elastomeric material dampens the shock. The suspension system for the wheel assembly (including any motorized drive shaft) essentially includes pivot-mounting the wheel assembly (wheel-motor) beneath the chassis frame, so that irregularities in the terrain encountered by the drive wheel cause the wheel assembly to flex inwardly (for bumps) or outwardly (for holes); in the resting position there is an elastomeric bumper or compression spring horizontally mounted adjacent to a stop-plate on the pivoting cradle carrying the wheel assembly (or wheel-motor), so that further inward flexion is dampened. The seat suspension system includes elastomeric bumpers essentially acting as fulcrums, to dampen shock by absorbing it directly and by cantilevering the seat for further shock absorption.

A lifter mechanism for an edge of a seat cushion includes a bracket detachable from and rotatable about a transverse bar. The bracket includes a forward lever and a rearward portion. The forward lever is coupled to a seat suspension. The rearward portion is coupled to a linkage. The linkage is coupled to a seatback. The forward lever raises an edge of the seat suspension upon the seatback pivoting to a predetermined reclined position.

A vehicle seat mounting system includes a seat mount plate and a vehicle mount plate. A vertically operable scissor linkage assembly is disposed between the seat mount plate and the vehicle mount plate and is oriented such that respective opposing ends of a first scissor arm and a second scissor arm are each secured to a respective one of the seat mount plate and the vehicle mount plate. A spring assembly is disposed between the seat mount plate and the vehicle mount plate and is oriented to cooperate with the scissor linkage assembly to resist translation between the vehicle mount plate and the seat mount plate. An adjuster assembly cooperates with the spring assembly and is operable to manipulate the proportion of the spring assembly that is available to be engaged to resist motion of the mounting system.
