ABSTRACT:
A locking device is provided for a self-coiling vehicle safety belt having a mounted coil spindle attachable to the vehicle, wherein a spindle gear keyed to the coil spindle can transmit the torque of accelerated belt withdrawal to a partially toothless planetary gear (or a pair of such) thus overcoming an anti-rotation bias, rotating said planetary gear or gears into mesh (beyond the toothless segment) with a fixed gear so that orbital and rotary motion of the planetary gear or gears continues until a stop surface provided on each planetary gear abuts with a fixed stop surface thereby locking the entire mechanism against further rotation in the direction of belt withdrawal.
