Abstract: A clamping device for a motor vehicle safety belt comprising a housing (2) traversed by the safety belt strap (1) coming from a strap winding device, respectively, from its winding shaft, as well as a first and a second wedge (3,4) arranged in the housing (2). The first wedge (3) forms a deviation member for the strap (1) on the side opposite to the strap winding device, respectively, to its winding shaft, and is provided with two skewed surfaces (12,13) delimiting a sharp angle and differently inclined with respect to the medial plane (16) of the first wedge (3) parallel to the strap (1) in the housing (2). By means of the inclined surface (13) delimiting with the medial plane (16) a larger angle, the first wedge (3) bears against a correspondingly inclined surface (15) of the housing (2) and, by means of the other inclined surface (12), against a correspondingly inclined surface (14) of the second wedge (4).

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.
