An operator seat system is provided that includes an operator seat and an armrest control center with an I/O (input/output) system that is connected to and moves with the operator seat. An armrest control center mount system may include a seat mount and an armrest control center mount that are attached to each other with an adjustment system that allows adjustment of the armrest control center with respect to the operator seat.

Embodiments of the invention provide a valve-control assembly for a vehicle seat that includes a pneumatic control valve configured to control at least one seat adjustment function. A control switch is configured to operate the pneumatic control valve, and a cover structure is arranged to one or more of at least partly cover the pneumatic control valve or at least partly surround the control switch. The control switch includes a first tab, and the cover structure includes a second tab. The first tab is configured to engage the second tab, when the control switch is actuated by a predetermined amount, to secure the control switch against movement and thereby secure the pneumatic control valve in an open configuration.

A vehicle seat assembly includes a housing seat attachment portion with hooks in receipt of suspension wires. A housing bracket extends from a housing sidewall to provide a housing cavity and a housing opening. The housing bracket is spaced above the vehicle floor by at least fifty millimeters to provide clearance between the housing bracket and the vehicle floor. A pump is received within the housing cavity adjacent to the seat attachment portion. A cover is fastened to the housing seat attachment portion and the housing bracket to at least partially enclose the housing opening and to retain the pump within the housing. A light source is received within the housing cavity and is adjacent to the seat attachment portion to minimize a height of the housing. The light source is oriented away from the seat attachment portion to illuminate a region beneath the seat bottom frame.

A vehicle seat is provided with a wire that, in the event of a vehicle frontal collision, enables a pulling load applied by a vehicle occupant to a webbing to be transmitted between a cushion frame of a seat cushion and a movable rail of a sliding device. One end portion of the wire is anchored to a first anchoring member of the movable rail, while another end portion of the wire is anchored to a second anchoring member of the cushion frame.

A vehicle seat having a vehicle seat underbody, comprising: a base plate; a side horizontal suspension; a rolling suspension comprising a rod element rotatably mounted with respect to the side horizontal suspension; a scissors-type frame having a first swing and a second swing, wherein the first swing is connected by a first slide element to the rod element and the second swing is connected by a second slide element to the rod element and the first swing is connected to the first slide element and the second swing is connected to the second slide element; a first element carrier; a lengthwise horizontal suspension; and a first spring element, which is connected on the one hand to the first element carrier and on the other hand to the base plate or one of the swings.

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.

Adjustable height limiter for a vehicle seat, comprising: a main body with a slot having a first end and a second end, a piston rod element which is displaceable with respect to the main body and has a pin element which is guided in the slot, a sleeve element which is rotatable with respect to the main body and at least partially surrounds the main body, the sleeve element having a boundary which is helical with respect to the main body, the boundary being arranged between the first end and the second end when viewed in the extension direction of the slot, and the pin element being arranged between the first end and the boundary.

The invention relates to a vehicle seat with a vehicle seat upper part and a vehicle seat lower part, the vehicle seat upper part and the vehicle seat lower part being connected to one another by means of a connecting means in such a way that the vehicle seat upper part can be moved relative to the vehicle seat lower part and, when the vehicle seat upper part moves relative to the vehicle seat lower part, the relative movement can be sprung by means of a spring element, the vehicle seat having an additional volume, the spring element being arranged between the vehicle seat upper part or the vehicle seat lower part and a proportion of the additional volume.

Vehicle seat comprising a vehicle seat top part, a vehicle seat bottom part and a guide device for guiding the vehicle seat top part with respect to the vehicle seat bottom part when the vehicle seat top part is deflected relative to the vehicle seat bottom part. The guide device includes a first assembly having a first lever element, a second lever element and a lever element connector. The first lever element and the second lever element are arranged so as to extend forwards in a longitudinal direction. The guide device also includes a second assembly having a third lever element, a fourth lever element and the lever element connector. The third lever element and the fourth lever element are arranged so as to extend backwards in a longitudinal direction. The guide device further includes a stabilization device having a fifth lever element, a sixth lever element and a seventh lever element, which are pivotally connected by means of a shared pivot axis. The fifth lever element is pivotally connected to the vehicle seat top part, the sixth lever element is pivotally connected to the vehicle seat bottom part and the seventh lever element is pivotally connected to the lever element connector.

A height adjusting mechanism (100) is provided for a vehicle seat (1), in particular for a utility vehicle seat, including a scissors-type frame (3). The height adjusting mechanism (100) includes a gas spring (12) that cooperates with the scissors-type frame (3) as well as a valve device (40) for ventilating and/or evacuating the gas spring (12). The valve device (40) is located on a control unit (110). The control unit (110) includes a control element (82) for actuating the height adjusting mechanism (100). A vehicle seat (1) is also provided including a height adjusting mechanism (100).
