Abstract
Abstract An active dynamic seat has a base, a stiff intermediate piece linked to the base and a seating part linked to the intermediate piece. The seating part is rigidly secured to the intermediate piece and the intermediate piece is mounted in such a way on the base that its central area can tilt in all directions and slide vertically. In addition, one or several restoring devices are arranged on the intermediate piece, in the area below the mounting point on the base, for restoring the tilting movement and at the same time the vertical displacement of the intermediate piece and the seating part.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
144 words
An active dynamic seat comprising: a base including a base part and a tilting joint assembly; a rigid intermediate piece, the intermediate piece including an upper end portion, a central portion, and a lower end portion; at least one restoring device interconnecting the base and the lower end portion of the intermediate piece; and a seat part connected to the upper end of the intermediate piece, wherein the seat part is rigidly connected to the upper end portion of the intermediate piece, the central portion of the intermediate piece is connected to the base via the tilting joint assembly such that the intermediate piece is tiltably moveable in a horizontal direction and is displaceable in a vertical direction, and the at least one restoring device restores the tilting movement and simultaneously restores the vertical movement of the intermediate piece and of the seat part.
Claim 2
Dependent Claim
144 words
An active dynamic seat comprising: a base including a base part and a tilting joint assembly; a rigid intermediate piece, the intermediate piece including an upper end portion, a central portion, and a lower end portion; at least one restoring device interconnecting the base and the lower end portion of the intermediate piece; and a seat part connected to the upper end of the intermediate piece, wherein the seat part is rigidly connected to the upper end portion of the intermediate piece, the central portion of the intermediate piece is connected to the base via the tilting joint assembly such that the intermediate piece is tiltably moveable in a horizontal direction and is displaceable in a vertical direction, and the at least one restoring device restores the tilting movement and simultaneously restores the vertical movement of the intermediate piece and of the seat part.
