Description

The invention relates to passive safety devices, in particular, to the construction of control devices of vehicle safety belts, for example, automobiles.

A regulating device is known which comprises a stopper with an overlay and a tongue with a curvature in the working area of the strip, and the stopper pad has tabs for fixing and guiding the stopper, as well as for reducing the slip of the tab 1.

However, this device is not sufficiently reliable and low-tech in manufacturing.

Closest to the invention is a control device of the length of a lmka vehicle safety belt, comprising a stopper covered by a belt, made in the form of a flat U-shaped plate with a lining, a tongue with a lining, and a spring 2 abutting the ends of the stopper.

The known device is not sufficiently reliable, since with a heavy load, the tongue plate moves, its rounded edge spreads out, and the remaining sharp edge cuts the needle.

The purpose of the invention is to increase the reliability of the device and manufacturability in the manufacture.

The goal is achieved by the fact that in a regulating device comprising a stopper covered by a lanyard, made in the form of a flat U-shaped plate with a lining, a tongue with a lining and a spring resting against the ends of the stopper, at the ends of the lower part of the lining of the stopper and the upper part of the lining of the tongue are made flat protrusions , and under the tongue, the lower part of the tong pad is secured with an additional plate with a window and a protrusion for fixing the spring entering the tong hole.

In order to avoid slipping

U

under load, at the ends of the lower part of the stopper's lining, there are bendings, and on the tongue, side cuts.

FIG. 1 schematically shows a regulating device, a plan view; in fig. 2 - the same, longitudinal section; in fig. 3 - the same, when a load is applied to the belt; in fig. 4 - device in axonometric projection.

The adjusting device of the length of the lmka vehicle safety belt contains a stopper 1, made in the form

a flat U-shaped plate with a lining 2, covering the locking lmku 3, tongue 4 with the lining 5 and a spring 7. abutting the ends 6 of the stopper i 7. The lower part 8 of the lining 2 of the stopper 1 and the upper part 9 of the lining 5 And with the dimensions corresponding to the ends 6 of the stopper 1, and under the tongue the lower part 12 of the lining 5 is fixed an additional plate 13 with a window 14 and a protrusion 15 entering the aperture 16 of the tongue 4 and serving to fix the spring 7. 1 and against slipping of lmki 3 at the ends 17 of the lower part 8 of the lining 2 s Bearing 1 are folds 18, and on the tongue 4 - lateral recesses 19.

The seat belt control device works as follows.

When lmka 3 is under load, the stopper 1 with lining 2, surrounding the working area of stopper 1, shifts towards the applied load and abuts against the lining 5 of tongue 4, clamping lmku 3. With further movement, the stopper 1 can turn to the moment when the flat protrusion io of the lining 2 of the stopper 1 is abutted into the tongue 4, so that the cutting of the lintel 3 does not occur. At the same time, the gap does not exceed the thickness of the lintel 3. parts of the lining 2 of the stopper 1 fix zazo and thereby eliminating the slip L pits, and serve as a guide stopper 1.

When adjusting the length of the lmk 3, which is under light load, the stopper 1 is under the load of the spring 7 fixed by means of a protrusion 15 on the plate 13, which does not allow the lmke to slide without a load.

The proposed device has high reliability during long-term operation of the seat belt, which ensures a high degree of passive safety of the driver or passenger of the vehicle. In addition, the proposed device is simple in design, compact and high-tech in production. The mass production of a regulating device presents no difficulties and is quite feasible with ordinary mechanized and automatic equipment.
