    摘要: A lock is fitted with a locking element and a control element which is rotated by a drive to-and-fro in order to axially reciprocate the locking element through a coaxial drive element between a locked and an unlocked position. The drive element and the control element are also configured coaxially and cooperative by means of a cross-pin which is axially displaceable in a transverse borehole of the inner drive element and by means of two helical inner channels as well as an adjoining plane terminal surface of the outer control element which runs perpendicular to the axis of rotation of the control element and is bounded by a side ramp running from the bottom of one channel past the other channel on the outside thereof toward the drive element. The drive element and control element cooperate in such manner that when the control element rotates in that direction in which the cross-pin runs in the channels toward the terminal surface, the drive element shall be commensurately axially displaced and remain in the axial position it has reached until the control element is rotated in the opposite direction and the cross-pin moves in the channels away from the terminal surface causing the drive element to move axially in the opposite direction.

    摘要: A device for rolling up a belt of a safety belt assembly for automobiles or the like of the kind employing a locking wheel on the reel spindle for the belt. The locking wheel is moved axially into engagement with a set of teeth on the housing to stop the reel spindle rotatably mounted in said housing. A locking member on the locking wheel first engages another set of teeth on the housing in response to accelerations of the belt in the withdrawal direction to bring the locking wheel to a stop in one of a limited number of known angular positions, whereupon it is moved axially to engage the first mentioned housing teeth with no risk of those teeth coming into tip-to-tip engagement. The locking member may be an inertia body and/or acted on by a separate inertia body, which may be a ring. The locking wheel may be in two parts, only one of which moves axially, and there may also be a locking responsive to accelerations of the automobile or the like which, using the two-part locking wheel, still allows the device to be mounted in an inclined attitude.
