Abstract: A storage device for a safety belt, including a rotably mounted coiling shaft to which one end of the belt is secured, inertia actuated means to lock the shaft against rotation in a direction of belt withdrawal and energy absorber means coupled between the shaft and the locking means.

Abstract: A storage device for a safety belt with vehicle-sensitive locking of belt in the direction of pull-out, including a coiling shaft rotatably mounted in a housing, a ratchet wheel axially movable on the coiling shaft and provided with peripheral teeth and with teeth on an end face, a pawl to arrest rotation of the ratchet wheel, an inertia member for moving the pawl into engagement with the peripheral teeth of the ratchet wheel, and teeth fast with the housing with which the end face teeth of the ratchet wheel co-operate and lock upon axial displacement thereof, wherein the ratchet wheel on that side remote from the end face teeth is stepped so that the top circle diameter of the peripheral teeth is smaller than the external diameter of the end face teeth. The ratchet wheel is mounted on the shaft by a smooth trunnion and has an internal thread which co-operates with an external thread on the shaft. Thus, within limits the ratchet wheel may rotate and move axially relative to the shaft.

Abstract: A storage device for a safety belt in which the safety belt is wound up on a shaft rotatably mounted in a housing. A ratchet wheel is carried by the shaft and rotation of the ratchet wheel is arrested by a pawl. The pawl is moved into engagement with the ratchet wheel by an inertia member comprising a ball which, in a normal position of rest, sits on a circular edge of a recess or aperture in a base member. The pawl is of such construction that its tip, which engages with the ratchet wheel, is longitudinally displaceable under a predetermined loading.
