ABSTRACT:
An inertia activated locking device for a motor vehicle seat of the type having a stationary part and an adjustable part, comprising a locking gear coupled to one part, a pinion meshing with the locking gear and being supported for free movement in an arcuate slot the center of curvature of which coincides with the center of rotation of the locking gear, and an arresting member spaced apart from an end of the arcuate slot at such a distance as to allow free rotation of the pinion when the locking gear rotates at a steady speed and to engage the pinion when the locking gear is abruptly accelerated so that it takes along the pinion as far as to the end of the slot facing the arresting member.
