Elastic support unit
First Claim
1. An elastic support unit, comprising a supporting element movable over a total path and including a rigid member connectable to an object, an elastic member which is elastic in a horizontal direction and in a vertical direction, and a sliding member located substantially between said elastic member and said rigid member and sliding over a sliding path dimensioned so that it starts to act upon exceeding the permissible elastic deformation of said elastic member said members being arranged so that first said elastic member deflects under the action of a horizontal force elastically horizontally until normally permissible stress in said elastic member so as to form a first elastic region, then after a horizontal restoring force of said elastic member exceeds a horizontal friction force between said sliding member and said rigid member said rigid member moves in a horizontal direction over the sliding path so as to form a second sliding region, and thereafter after exceeding said sliding path said elastic member is further elastically deformed by said rigid member with use of stress reserves between the permissible stress and a stress at the elasticity limit of said elastic element so as to form a third elastic region with the same elasticity as in said first elastic region and in said second sliding region, and then it is deformed plastically from a tensile limit stress to a breaking stress.

Abstract
An elastic support unit has a supporting element including an elastic part and a sliding part arranged so that under the action of load, first the elastic part is elastically deformed and the supporting element acts within a first elastic region, then the sliding part allows the supporting element to slide over a slide path and the supporting element acts within a second sliding region, and thereafter upon passing the sliding region the supporting element uses its stress reserves and after exceeding the stress reserves uses plastic deformation of the elastic part, so as to form thereafter an elastic stop and thereby act in a third additional region.
