Abstract:
1. A seat base of a person's seat with at least one backrest and one seat part to permit a controlled movement of the person's seat for the dissipation of kinetic energy and for the protection of the person sitting on the person's seat in the event of an accident taking place substantially in the direction of the seat, wherein the seat base comprises at least one pair of U-shaped tubular elements oriented sideways relative to an upright position and capable of being deformed, an upper end portion of each U-shaped tubular element, with respect to the height direction of the seat, characterized by an upper leg of the U-shaped tubular element arranged in a torsionally rigid manner substantially on a lower surface of the seat part and a lower end portion of each U-shaped tubular element, with regard to the height direction of the seat, characterized by a lower leg of the U-shaped tubular element arranged in a torsionally rigid manner substantially on an upper surface of a region of a vehicle floor on which the person's seat is arranged, wherein the U-shaped tubular element is non-symmetrical and has a single inflection point nearer the lower leg of the U-shaped tubular element than the upper leg of the U-shaped tubular element, and at least one pair of S-shaped tubular elements oriented upright and capable of being deformed, an upper end portion of each S-shaped tubular element, with respect to the height direction of the seat, is arranged in a torsionally rigid manner substantially on the lower surface of the seat part and a lower end portion of each S-shaped tubular element, with regard to the height direction of the seat, is arranged in a torsionally rigid manner substantially on the upper surface of the region of the vehicle floor, and wherein the pair of U-shaped tubular elements is arranged substantially in front of the pair of S-shaped tubular elements in the direction of the seat, wherein each end portion of the U-shaped tubular elements and the S-shaped tubular elements is fixedly secured in a non-rotatable manner.
