1. A chairlift chair safety barrier comprising: an anchoring portion; anda projecting portion which projects downwardly from the anchoring portion attached to a front bar of a safety frame of a chair of a chairlift, said projecting portion having a front side and a back side, wherein only the front
1. A chairlift chair safety barrier comprising: an anchoring portion; anda projecting portion which projects downwardly from the anchoring portion attached to a front bar of a safety frame of a chair of a chairlift, said projecting portion having a front side and a back side, wherein only the front side is provided with a one-directional weakening configuration to provide: (i) a substantial bending capability for the projecting portion to bend in a first direction under stress applied to the front side of the projecting portion, and (ii) a substantial rigidity to the projection portion for resisting a substantial bending in a second, opposite direction under stress applied to the back side of the projecting portion. 2. The chairlift chair safety barrier of claim 1, wherein the projecting portion includes a first wall crosswise to a travelling direction and has at least one weakened portion to promote flexibility of said projecting portion. 3. The chairlift chair safety barrier of claim 2, wherein the at least one weakened portion is defined by a groove. 4. The chairlift chair safety barrier of claim 3, wherein the groove is substantially parallel to the anchoring portion. 5. The chairlift chair safety barrier of claim 3, wherein the first wall includes at least one face and said groove is formed in the first wall along said at least one face. 6. The chairlift chair safety barrier of claim 2, wherein the projecting portion includes a second wall facing the first wall and connecting the anchoring portion to the first wall. 7. The chairlift chair safety barrier of claim 6, wherein the anchoring portion, the first wall, and the second wall define a gap. 8. The chairlift chair safety barrier of claim 6, wherein the second wall is thinner than the first wall. 9. The chairlift chair safety barrier of claim 6, wherein the first wall and the second wall are integral with the anchoring portion. 10. The chairlift chair safety barrier of claim 1, wherein the projecting portion is elastically flexible about an axis substantially parallel to the anchoring portion. 11. The chairlift chair safety barrier of claim 1, wherein said anchoring portion includes a polymer material. 12. The chairlift chair safety barrier of claim 1, which includes a cover enclosing at least the anchoring portion. 13. The chairlift chair safety barrier of claim 12, wherein the cover encloses at least part of the front bar adjacent to the anchoring portion. 14. The chairlift chair safety barrier of claim 12, wherein said cover includes a polymer foam. 15. The chairlift chair safety barrier of claim 1, which includes three projecting portions which are configured to be positioned alongside thighs of a passenger. 16. The chairlift chair safety barrier of claim 1, wherein the projecting portion is elastically flexible under stress oriented in a plurality of first directions. 17. The chairlift chair safety barrier of claim 16, wherein the projecting portion is substantially rigid under stress oriented in a plurality of second directions, each of the plurality of first directions being different from each of the plurality of second directions. 18. The chairlift chair safety barrier of claim 1, which includes a plurality of projecting portions. 19. The chairlift chair safety barrier of claim 1, wherein the stress is applied to the back side of the projecting portion when a passenger slides out of the chair of the chairlift and bumps into the back side of the projecting portion. 20. A chairlift chair safety barrier comprising: an anchoring portion; anda projecting portion which projects downwardly from the anchoring portion rigidly attached to a front bar of a safety frame of a chair of a chairlift, said projecting portion having a front side, a back side and at least one groove substantially parallel to the anchoring portion to provide: (i) a substantial bending capability for the projecting portion to bend in a first direction under stress applied to the front side of the projecting portion, and (ii) a substantial rigidity to the projection portion for resisting a substantial bending in a second, opposite direction under stress applied to the back side of the projecting portion. 21. The chairlift chair safety barrier of claim 20, wherein the stress is applied to the back side of the projecting portion when a passenger slides out of the chair of the chairlift and bumps into the back side of the projecting portion.
