Abstract

A device for adjusting a belt, especially a safety belt for use in motor vehicles and the like, which device comprises a U-shaped housing which is fitted to the vehicle either directly or by way of a belt and in the lateral limbs of which is provided a clamping roller, longitudinally displaceable in slots in the direction in which the belt is pulled, the belt being laid around this clamping roller.

Claims

1. A device for adjusting a belt, especially a safety belt for use in motor vehicles and the like, which device comprises a Ushaped housing with a base mounted to the vehicle, said housing provided with a non-rotatable clamping roller, surrounded at least partially by a shaped part, said roller longitudinally displaceable in said housing in slots in the direction in which the belt is pulled, a belt laid around the clamping roller with the slots extending parallel to the base of the housing, bores located in the housing, a locking roller offset from the slots rotatably mounted in the bores and connected to and rotating with a rocking lever, the arms of which each have a control cam face cooperating with the clamping roller.

2. A device according to claim 1, characterized in that the bores for accommodating the locking roller are offset towards the base of the housing at a distance from the slots.

3. A device according to claim 2, characterized in that the clamping roller and the locking roller are knurled.

4. A device for adjusting a belt, especially a safety belt for use in motor vehicles and the like, which device comprises a U-shaped housing with a base mounted to the vehicle, said housing provided with a non-rotatable clamping roller, surrounded at least partially by a shaped part, said roller longitudinally displaceable in said housing in slots in the direction in which the belt is pulled, a belt laid around the clamping roller with the slots extending Parallel to the base of the housing, bores located in the housing, a locking roller offset from the slots rotatably mounted in the bores and connected to and rotating with a rocking lever, the arms of which each have a control cam face cooperating with the clamping roller, characterized in that (the clamping roller is non-rotatable and is surrounded at least partially by a) shaped part is on a side opposite the control cam face.

5. A device according to claim 4, characterized in that a tension spring, disposed in a slot in the base of the housing, is attached to the shaped part, the other end of the spring being secured to the base of the housing.

6. A device according to claim 5, characterized in that a transverse web is fitted between the arms of the rocking lever at that side thereof opposite the control cam face.

7. A device according to claim 6, characterized in that the shaped part takes the form of a bent steel wire.
