PCT No. PCT/EP92/00265 Sec. 371 Date Nov. 17, 1992 Sec. 102(e) Date Nov. 17, 1992 PCT Filed Feb. 6, 1992 PCT Pub. No. WO92/17252 PCT Pub. Date Oct. 15, 1992.A retainer member (26) is guided for displacement at a housing (24) which is adapted to be fastened to a ski (10), the retainer member being biased by a spring assembly (70) in the direction toward a ski boot (12). The housing (24) contains a support member (40) kept in an inoperative position, in which it forms a thrust bearing for the spring assembly (70), by a locking member (50) as long as the latter is in locking position. Normally, a shoulder (48) formed at a pawl (46) which is pivotable about a transverse pivot axis (44) presses against the locking member (50). An electromagnet (60) is associated with the pawl (46) and becomes energized when the retainer member (26) or a hold-down member (30) supported on the same runs the risk of becoming overloaded. Upon excitation of the electromagnet (60), its armature (62) hits against the pawl (46) which then releases the locking member (50). Thereupon the support member (40) moves into its retracted position so that the retainer member (26) and the hold-down member (30) both are relieved of the pressure of the spring assembly (70), thus releasing the ski boot (12). |
