Abstract
Described is a seat (10) having a spring means (36) with which the springing characteristic of the seat (10) can be adjusted as desired. For that purpose a two-armed pivot lever (38) is provided on a back element (34) of the seat (10) at least approximately horizontally and is pivotable about a central mounting axis (40). At least one at least approximately horizontally arranged tension spring (48) is fixed by its one end portion (50) to the one arm (44) of the pivot lever (38), the second end portion (54) of the tension spring (48) being fixed to a fixing portion (56) of a support lever (58). The fixing portion (56) is at least approximately aligned with the mounting axis (40). The support lever (58) is mounted pivotably to the back element (34) and is pivotally connected by its fixing portion (56) to a scissor element (18) of a scissor support assembly (16).
