Seat device for a tilting vehicle

A seat apparatus for a tilting vehicle, comprising:

• a seat member having a seat face on which a user of the tilting vehicle is seatable, the seat member being acted on with a force acting in an active direction, wherein the active direction extends transversely relative to the seat face;
• and
• at least one carrier unit, wherein the at least one carrier unit comprises:
• at least one resiliently bendable and/or deformable first carrier portion on which the seat member is arranged,
• at least one rigid, non-flexible, second carrier portion, and
• at least one hollow space arranged between the at least one first carrier portion and the at least one second carrier portion and extending parallel with or obliquely relative to the seat face, wherein the at least one first carrier portion and the at least one second carrier portion are spaced apart from each other without contact by the at least one hollow space and wherein an elastic deformation of the at least one first carrier portion toward the at least one hollow space is enabled by the at least one hollow space;
• and
• at least one adjustment unit comprising at least one adjustment member which is movably arranged in the at least one hollow space and by which the at least one first carrier portion is supported on the at least one second carrier portion, and which adjustment member is changeable from a first support position, in which the at least one first carrier portion comprises a first spring rate, into a second support position, in which the at least one first carrier portion comprises a second spring rate differing from the first spring rate.
