PCT No. PCT/CH79/00019 Sec. 371 Date Oct. 7, 1979 Sec. 102(e) Date Aug. 28, 1979 PCT Filed Feb. 6, 1979 PCT Pub. No. WO79/00601 PCT Pub. Date Aug. 23, 1979.A shock absorption thrust mechanism includes a thrust piece (19) which is used as a stop for a moving body in motion. This thrust piece 19 is prone to displacement under the effect of kinetic energy of the moving body, against the action of a spring (20) and a shock absorber (21). The displacement of the thrust piece (19) depends on the kinetic energy of the moving body under shock, which is prejudicial particularly with respect to typewriters, where this displacement occurs in the stop position of the moving body or ensures the control of a function. In order to obtain a constant displacement of the thrust piece (19), the mechanism includes a driving device (10, 24) which moves the thrust piece (19) in a predetermined movement, the driving device (10, 24) acting jointly with the moving body on the thrust piece (19). |
