ABSTRACT:
A seat, especially an airplane or vehicle seat, has a seat part placed on the stand-type seat structure (12) in relation to a base and provided with a bearing part (18) on its front side. The bearing part (18) is embodied in a flexible manner and can move in the direction of the seat structure (12) when a predefined seating load is exerted on it. When the load is discharged, it can move back into its initial position in the opposite direction from the seat structure (12). This arrangement creates a seat whose front part is maintained in a flexible manner such that the front area of the seat part yields according to the seating load exerted by the seat user. The pressure forces are limited to the lower side of the upper thighs of the seat user. As a result, the cross-sections of the veins in that region are not reduced, but are maintained such that the circulation of the blood is not impeded, significantly reducing the risk of thrombosis.
