A vehicle seat comprising a seat part extending in the vehicle longitudinal direction (X) and in the vehicle transverse direction (Y) and including a backrest part is provided. The vehicle seat includes a seat substructure for suspending and/or damping at least the seat part with respect to the body of a vehicle. The seat substructure comprises at least one horizontal suspension device that includes a body-side lower part and a seat-part-side upper part displaceable with respect thereto. A coupling device is arranged interactively between the seat-part-side upper part and the body-side lower part, and includes a deformable suspension element as a first coupling element and a bearing and deformation device as a further coupling element.

A reclinable passenger seat including a base, a seat pan frame having a front end connected to the base via a first fixed pivot, a support arm having one end connected to the base via a second fixed pivot aft of the first fixed pivot, and a backrest frame having an upper backrest member and a lower backrest member. An opposed end of the support arm is pivotally connected to the lower backrest member at a first location spaced from the upper backrest member. A rear end of the seat pan frame is pivotally connected to the lower backrest member at a second location between the first location and the upper backrest member. The backrest frame and seat pan frame are configured to move simultaneously between a sitting configuration and a reclined configuration through pivoting motion about the fixed pivots and about the two locations.

The invention relates to a vehicle seat comprising a vehicle seat upper part and a vehicle seat lower part, which are spaced apart from one another along a height axis and are connected to one another by means of a scissor frame arrangement, wherein the scissor frame arrangement comprises at least one inner swinging arm and at least one outer swinging arm, wherein the at least one inner swinging arm and the at least one outer swinging arm are mechanically coupled, whereby an angle of inclination of the vehicle seat upper part relative to the vehicle seat lower part can be specified, wherein the mechanical coupling comprises an arm element and a first connecting element pivotably connected thereto, wherein the angle of inclination can be specified by a length of the first connecting element.

A vehicle seat is disposed on a floor portion of a passenger compartment, and includes first and second upper seat tracks, and a seat bottom disposed thereon. First and second lower seat tracks are each disposed longitudinally in the vehicle and secured to the floor portion at respective fore and aft attachment locations, wherein each of the first and second upper seat tracks is slidably disposed in a respective one of the first and second lower seat tracks. A support damper is disposed between the floor portion and one of the first and second lower seat tracks and disposed between the respective fore and aft attachment locations. The support damper is disposed at a longitudinal position between the respective fore and aft attachment locations at a maximum vertical deflection point of the respective one of the first and second lower seat tracks relative to the floor portion.

A method performed by one or more processing devices for ensuring that a vehicle seat top is qualified for use with a seat base for a vehicle seat, the method comprising: receiving information that identifies a type of vehicle seat top for coupling to the seat base; verifying that the vehicle seat top is authorized for use with the seat base; and in response to verifying, retrieving, based on the received information that identifies the type of vehicle seat top, pre-determined values of controller parameters of a closed loop control system for isolating vibrations from the vehicle seat top, wherein the predetermined values of the controller parameters are specifically tuned for the vehicle seat top.

A vehicle seat assembly including a vehicle seat mounted on a spring suspension system, the seat assembly having a safe mode into which it can be placed when the seat is unoccupied to avoid damage to the spring suspension system due to forces generated within the suspension system of an unoccupied seat. The seat assembly is configured to be placed in communication with a control system of an associated vehicle in which it is mounted and to invoke the safe mode in dependence on the vehicle being placed in a predetermined operating mode of the vehicle which is indicative that the seat will be unoccupied.

A passenger restraint system for roller coasters designed to maintain a passenger in an essentially seated or lying posture, with suspended feet. The passenger restraint system includes a fixed column and a seat column designed to support and hold the passenger, which seat column is coupled to the fixed column so as to be displaceable with respect to the fixed column during a roller coaster ride. The seat column is coupled to the fixed column by an articulated linkage, and the passenger restraint system further includes a balancing device ensuring a balancing of the seat column, which balancing device is fixed, at a first end, to the fixed column and, at a second end, to the seat column. The balancing device can advantageously be configured to ensure a vertical travel of the seat column during the roller coaster ride in dependence of a vertical acceleration exerted on the passenger.
