Spring element for use in seat surface and back rest of vehicle i.e. car, seat, has blocking element blocking definite portion of spring deflection, where blocking element is collapsed by plastic deformation upon reaching defined load

摘要

The spring element (2) has a blocking element (4) blocking a definite portion of spring deflection that is necessary for adaptation to a body form, where the blocking element is collapsed by plastic deformation upon reaching a defined load. The blocking element partially embraces a blocking winding. The blocking element is monolithically designed, and consists of multiple individual components. The blocking element is a clip encompassing a flexible material.
