Abstract (en)
[origin: WO2015173372A2] The invention relates, in particular, to a shock absorbing clutch device for a timepiece, comprising a clutch wheel (2) able to take an engaged position and a disengaged position, a clutch member (1) bearing said clutch wheel and a clutch cam (6) engaging with the clutch member (1) to define the engaged position and disengaged position of the clutch wheel (2). According to the invention, the device also comprises a locking member (12) rigidly attached to the clutch cam (6) and an intermediate member (9) controlled by the clutch member (1). Said intermediate member (9) is intended to engage with the clutch member (1) and the locking member (12) to prevent or limit the movement of the clutch member (1) under the effect of a shock when the clutch wheel (2) is in the engaged position, to thus avoid the clutch wheel (2) leaving the engaged position.
