1. A belt latch for a safety belt comprising:
- a connection plate for connecting the belt latch to a buckle;
a latch main body being rigidly connected to the connection plate and having a cut-open hollow cylindrical portion with a concave inner surface, two side elevations disposed at opposite ends of the cut-open hollow cylindrical portion to terminate the concave inner surface, and an upper eye and a lower eye for receiving the belt into the cut-open hollow cylindrical portion;
a bending and clamping element with a bending edge and a clamping edge and a convex outer surface is slidingly arranged on the concave inner surface of the cut-open hollow cylindrical portion via its convex outer surface to rotate around a rotation axis in relation to the latch main body from a first deflecting position to a second clamping position if the force in the belt exceeds a defined force; and
a lid removably attached to the latch main body such that it covers the cut-open hollow cylindrical portion;
the lid having a leading edge and a trailing edge engaging the latch main body and two opposing edge covering portions in overlapping engagement with the respective side elevations to cover the opposite ends of the cut-open hollow cylindrical portion, the edge covering portions provided with first fixing means arranged to engage corresponding second fixing means provided at the respective side elevations.

Abstract
A belt latch including a connection plate, for connecting it to a buckle, and a latch main body rigidly connected thereto. The latch main body may have a cut-open hollow cylindrical portion housing a bending and clamping element arranged to rotate in relation thereto from a deflecting position to a clamping position if the force in an associated belt exceeds a defined force. A lid may be arranged to cover the cut-open hollow cylindrical portion.

7. A belt latch for a safety belt comprising:
-
a connection plate for connecting the belt latch to a buckle; a latch main body connected to the connection plate, the latch main body having a cut-open hollow portion, two side elevations disposed at opposite ends of the cut-open hollow portion to terminate an inner surface thereof, and an upper eye and a lower eye for receiving the belt into the cut-open hollow portion; a bending and clamping element configured to rotate around a rotation axis in relation to the latch main body from a first deflecting position to a second clamping position if the force in the belt exceeds a defined force; and a lid removably attached to the latch main body such that it covers the cut-open hollow portion and a portion of the belt therein, the lid having two opposing edge covering portions in overlapping engagement with the respective side elevations to cover the opposite ends of the cut-open hollow portion, the edge covering portions provided with first fixing means arranged to engage corresponding second fixing means provided at the respective side elevations. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A belt latch for a safety belt comprising:
-
a connection plate for connecting the belt latch to a buckle; a latch main body being rigidly connected to the connection plate and having a cut-open hollow cylindrical portion with a concave inner surface, two side elevations disposed at opposite ends of the cut-open hollow cylindrical portion to terminate the concave inner surface, and an upper eye and a lower eye for receiving the belt into the cut-open hollow cylindrical portion; a bending and clamping element with a bending edge and a clamping edge and a convex outer surface is slidingly arranged on the concave inner surface of the cut-open hollow cylindrical portion via its convex outer surface to rotate around a rotation axis in relation to the latch main body from a first deflecting position to a second clamping position if the force in the belt exceeds a defined force; and a lid removably attached to the latch main body such that it covers the cut-open hollow cylindrical portion and having a leading edge and a trailing edge engaging the latch main body and two opposing edge covering portions in overlapping engagement with the respective side elevations to cover the opposite ends of the cut-open hollow cylindrical portion, the edge covering portions provided with first fixing means arranged to engage corresponding second fixing means provided at the respective side elevations, and the lid further comprising a protruding member extending from the trailing edge and positioned such that the bending and clamping element when rotated to the second clamping position contacts the protruding member to push against the trailing edge and thereby cause the trailing edge of the lid to deflect outwardly of the cut-open hollow cylindrical portion, said outward deflection of the trailing edge causing the lid to bend such that the two opposing edge covering portions pinch inwardly on the respective opposing side elevations and urge the first fixing means into firmer engagement with the second fixing means.
