The collapsible baby carriage or doll's pram chassis according to claim 1, wherein the actuating element is mounted on a joint mount at at least one of the at least two chassis posts, at which in addition a joint for one of the support struts is provided. 3. The collapsible baby carriage or doll's pram chassis according to claim 2, wherein two stabilising rods are arranged in parallel or in mirror image, which are connected together by way of a connecting element, and that the actuating element or the adjusting device is coupled with the connecting element, wherein the connecting element is attached to the two rear parts of the stabilising rods. 4. The collapsible baby carriage or doll's pram chassis according to claim 1, wherein the seat underside of the insert presses on the actuating element or a holding-down element attached thereto engages on the actuating element. 5. The collapsible baby carriage or doll's pram chassis according to claim 4, wherein two stabilising rods are arranged in parallel or in mirror image, which are connected together by way of a connecting element, and that the actuating element or the adjusting device is coupled with the connecting element, wherein the connecting element is attached to the two rear parts of the stabilising rods. 6. The collapsible baby carriage or doll's pram chassis according to claim 1, wherein the lifting linkage comprises rigid elements which produce pressing-down of the parts of the stabilising rods when the actuating element is pressed down. 7. The collapsible baby carriage or doll's pram chassis according to claim 6, wherein two stabilising rods are arranged in parallel or in mirror image, which are connected together by way of a connecting element, and that the actuating element or the adjusting device is coupled with the connecting element, wherein the connecting element is attached to the two rear parts of the stabilising rods. 8. The collapsible baby carriage or doll's pram chassis according to claim 1, wherein the Bowden pull comprises a holder supported on a bridge element and actuates an entraining eccentric or an angle lever, which is rotatably mounted on the bridge element and is attached to the upwardly protruding arm thereof for an entrainer rod, a cable or a chain, which on actuation of the actuating element introduces a tension force in the region of the toggle joint at the pivotable part of the stabilising rod. 9. The collapsible baby carriage or doll's pram chassis according to claim 8, wherein two stabilising rods are arranged in parallel or in mirror image, which are connected together by way of a connecting element, and that the actuating element or the adjusting device is coupled with the connecting element, wherein the connecting element is attached to the two rear parts of the stabilising rods. 10. The collapsible baby carriage or doll's pram chassis according to claim 1, wherein two stabilising rods are arranged in parallel or in mirror image, which are connected together by way of a connecting element, and that the actuating element or the adjusting device is coupled with the connecting element, wherein the connecting element is attached to the two rear parts of the stabilising rods. 11. The collapsible baby carriage or doll's pram chassis according to claim 10, wherein two stabilising rods are arranged in parallel or in mirror image, which are connected together by way of a connecting element, and that the actuating element or the adjusting device is coupled with the connecting element, wherein the connecting element is attached to the two rear parts of the stabilising rods. 12. The collapsible baby carriage or doll's pram chassis according to claim 1, wherein an adjusting device with rigid elements, particularly rods, is provided between the actuating element and the pivotable part of the stabilising rod, which rigid elements on return of the actuating element to the locking setting urge the pivotable parts into the locking position when the carriage chassis with the at least two chassis posts and the support struts is erected. 13.
