"Buckle"

The invention relates to a buckle according to the preamble of claim 1. Such a buckle is used in connection with a pair of tapes or straps or parts thereof used. In particular, the invention relates to buckles used on child safety belts. Such buckles should be easy to use and, in particular, to be loosened in order to fasten the seat belt to a child to put on or to remove it again.

Such a buckle is described in GB-PS 1,093,854. This buckle includes fasteners for attachment a band or belt, a hook which can come into engagement with a sleeve part, this sleeve part is attached to a band or a belt, as well as a detachable, spring-loaded pawl. These The purpose of the pawl is to close the hook in order to prevent the eyelet from loosening from the hook. The blocking

The handle is provided with a part for opening of the hook can be pressed down against the spring action and for this purpose it is swiveled around an axle that is at a distance from the hook. The hook, the middle for fastening of the belt or belt and a pivot pin load-bearing stops are integral with one another. The pawl is designed in the shape of a channel. She owns lateral Flanges hinged to the trunnions.

The assembly of the pivot pin and also the attachment The pawl on the pivot pin is a difficult, cumbersome one Procedure. With the invention, on the other hand the manufacturing time and cost can be reduced. Furthermore, a robust and thus in The use of a stable construction can be created.

Serve to solve this problem, based on the generic term of claim 1, first of all the features of the characterizing part of claim 1. With this arrangement, during manufacturing the spring engages the pawl and inserted into it, the flap engaging in the slit. The hook-shaped end is deformed so that the pawl can attack it.

With the features of claim 2 is in the closed position of the hook achieves a practically continuous surface.

The resilient device can be a bent leaf spring with a spring part between the rear flange and

the edge part intended to rest on the hook and furthermore with a further spring part which extends towards the hook and engages the hook part, the hook part having a stop for the end of this spring part. In detail, reference is made to the features of the claims
3 and 4 referenced. This allows the spring to attack the stop.

With the features of claim 5 is also the underside an essentially continuous, even surface reached the buckle.

Further advantages and features of the invention emerge from the following description and the associated
Drawing. In this shows:

FIG. 1: an exploded perspective view of a buckle according to FIG
Invention, together with the associated eyelet part,

Fig. 2: a longitudinal section through the

Buckle, with it with the ossnteil is engaged.

The buckle includes a plate-shaped part 11, the
is provided at one end with slots 12, 13 for the attachment of straps, as detailed in GB-PS
1,093,854. The opposite end of the part 11 is shaped so that it is an elongated
Hook 14 forms. A further slot 15 is provided parallel to the slot 13, the one between these

both slots 13 and 15 located leil 18 something the plane of the plate-shaped part 11 is pushed out is. A small stop, which has a stop surface 16, is formed between the slot 15 and the hook 14 .

A pawl or clasp 20 C (hereinafter referred to as pawl 20) with a channel shape is provided. It has a flat cover part 21 which is provided with a bent edge part, preferably a peripheral edge 22, which is used for attack. The channel shape is further determined by side flanges 23, 24 and a rear flange 25, which is located between the side flanges at the end opposite to the edge 22. An elongated tab 26 extends outwardly from the rearward flange 25. This tab 26 engages in the slot 15 and under the adjacent, pushed-up part 16, so that the pawl is pivotable about this approach. A spring 30 presses the pawl into a position in which the hook is closed, with the edge 22 below the hook 14 resting against it. In this position, the outer surface of the lid part 21 is substantially in one plane with the corresponding surface of the upper part of the hook 14, while the outer surface of the lug 26 is substantially in one plane with the outer surface of the plate part.

The spring 30 consists of a leaf spring which, by bending, is divided into a first and a second part 31 and 32, respectively is that they form an acute angle with each other. The spring is between the pawl 20 and your plate

molded part 11 encased. The free end of the first Spring part 31 engages the downwardly bent or deformed edge edge 22, while the other end of this first spring part rests on the rear flange 26 and thereby the position of the spring relative to the pawl 20 determined. The free end of the second spring part 32 engages the stop surface IB, so that the Location of both the spring and the pawl relative to the plate-shaped part 11 is determined.

The pawl can open or make accessible of the hook 14 are depressed so that an eyelet 40 can be brought into engagement with the hook. With the Letting go of the pawl closes the hook, so that the engagement of the hook with the nozzle part is fixed held d. H. is secured. O'er outer part 40 has an eyelet 41 and two slots 42, 43, which accommodate the straps of a belt, in particular a seat belt to serve.

The final shape or profile design of the Hook 14 takes place after the pawl and the spring are mounted on the plate-shaped part. Such Arrangement is simple and can be done quickly
