ABSTRACT:
A device for limiting the acceleration which an oscillating weight (1) used to drive or wind a power generator powering an instrument of small volume, can undergo, includes a bearing raceway (2) against which such weight abuts when it undergoes an acceleration substantially exceeding that occurring in normal use of the instrument. For this purpose, the weight (1) is elastically mounted on a moving support member (4) so as to move in the plane of such weight which is then braked by the bearing raceway (2) when the weight undergoes an acceleration which exceeds a certain maximum value.
