Suspension device for a vehicle seat, comprising an upper suspension portion and a lower suspension portion, which are interconnected by a first swivel connector and a second swivel connector, and the first and the second swivel connector are pivoted in each case about a swivel pin in the case of an oscillating movement of the upper suspension portion relative to the lower suspension portion, wherein a first toothed wheel element which is rotatable about a first axis of rotation is arranged on the first swivel connector for adjusting a position of a first spring unit, by means of which a spring force and a spring rate of the suspension device can be changed, the first toothed wheel element being in operative contact with a second toothed wheel element which is rotatable about a second axis of rotation.

Suspension device for a vehicle seat, comprising an upper suspension portion and a lower suspension portion, said suspension portions being connected to one another by a first swivel connector and a second swivel connector, said first swivel connector being arranged on the lower suspension portion in such a way that it can swivel about a first swivel pin, and said second swivel connector being arranged on the lower suspension portion in such a way that it can swivel about a second swivel pin, a first tension spring and a second tension spring being respectively connected to the first swivel connector by means of a first end region and to the upper suspension portion or the lower suspension portion by means of a second end region, wherein the first end region of the first tension spring is attached to the first swivel connector at a first distance therefrom, and the first end region of the second tension spring is attached to the first swivel connector at a second distance therefrom, the length of the first distance being variable.

A seat, such as a vehicle seat, includes an assembly for use in adjusting a seat support relative to a seat frame to provide a varying level of support to a seat occupant. The assembly includes a chassis mounted on the seat support, a screw drive supported on the chassis, an actuator coupled to the screw drive, a drive block engaging the screw drive, and first and second cables extending from the assembly for adjustable attachment to the seat frame.

The present disclosure discusses an active seating system that includes a load leveling mechanism. The load leveling mechanism includes a force bias actuator assembly, a roll actuator assembly, a heave actuator assembly, a first torsion rod connected to the force bias actuator and the roll actuator, and a second torsion rod connected to the force bias actuator and the heave actuator. Each of the force bias actuator assembly, roll actuator assembly, and heave actuator assemblies comprises a housing, a DC motor disposed within the housing, and a ball screw with a driveshaft, the driveshaft of the ball screw being coaxial with a rotor of the DC motor. The active seating system also includes a seat top and an interface configured to mount the seat top to the load leveling mechanism.

A seat control device includes: a control unit configured to control movement of an electric seat; and a seating detection unit configured to detect whether an occupant is seated on another seat. When the electric seat moves in a direction of the other seat, in a case in which the occupant seated on the other seat is detected, the control unit moves the electric seat in the direction of the other seat in a first control mode including a process for suppressing the occupant from being pinched between the electric seat and the other seat. When the electric seat moves in the direction of the other seat, in a case in which no occupant seated on the other seat is detected, the control unit moves the electric seat in the direction of the other seat in a second control mode not including the process.

Systems and methods are provided herein for managing a vehicle fleet based on compliance regulations, and, in some embodiments, involve blockchain or other distributed ledger technologies. Systems and methods for managing a vehicle fleet based on compliance regulations may include receiving a service request, wherein the service request is a request for a passenger ride or a request for a cargo transport, receiving first information for a first node, wherein the first information comprises a vehicle size, a vehicle weight, and/or a number of seats, receiving second information comprising a first threshold number of vehicle occupants and/or a first threshold vehicle occupant weight limit, determining that the first threshold number of vehicle occupants or the first threshold vehicle occupant weight limit are exceeded, and sending an indication that the first node has not accepted the service request.

A device for operating a seating arrangement that can be folded out of or into a vehicle. Includes a control unit that receives and executes an activation command by an authorized vehicle user and third parties for folding the seating arrangement out of a region inside the vehicle into a region accessible from outside the vehicle.

A motor vehicle seat may have a seat squab, a back rest, and kinematics for moving the vehicle seat from a use position suitable for conveying people to a non-use position or access position. The access position makes accessing a rear row of seats easier. The seat may be moved by a drive device from the use position to the non-use position, and vice versa. The seat may have a rear foot with a locking device that can be locked with a counter-element for securing in the use position. The seat may also have a protection device arranged in the region of the locking device for detecting an obstacle in a movement path of the rear foot when the vehicle seat is moved from the non-use position to the use position.

Systems, methods, and computer-readable media are disclosed for optimized driver seat and pedal positioning using ulna length. An example method may include determining, at a first time and using a sensor of a vehicle, an ulna length of a vehicle user. The example method may also include automatically adjusting a seating position of the vehicle user to a first seating position based on the ulna length of the vehicle user.

A vehicle seat (11) includes a seat frame (22a) having an opening (46) in a plate-shaped part (43), andan actuator (31) mounted on the plate-shaped part (43). Accordingly, it is possible to provide a vehicle seat that further contributes to quietness in the interior of a vehicle.
