However, it has been shown that the known execution forms either require additional space, or not sufficient despite a high level of manufacturing complexity Have operational safety ..

The invention is therefore based on the object of a lock of the type described above with a space-saving; manufacturing technology to equip simple and long-term reliable closing and extension springs.

According to the invention, this object is achieved in that the %

Closing and ejecting spring as coiled or spiral-shaped |

The main spring is designed with an extended end I.

on the lock bolt and with its other end on a ' Eject lever mounted pivotably on the lock acts.

The design of the compression and ejection spring as a friction spring, which can be designed as a helical spring or a spiral spring, results in a space-saving element, the values of which are much more favorable compared to the known designs. ■ Effect associated with an increase in safety and the duration of the stay.

Particularly advantageous is s, if the al3 Leger for the closing and ejection spring formed ejection lever has a bearing pin on which the S _c hließ- and ejection spring engages with one end. Servant pivot pin also serves to set the ejection lever to 'J? ^ .len. g TJchlos ^r .s, v / whether it is spatially fixed by the closing and ejector spring in relation to its pivot axis.

With some lock designs it can also be. be advantageous if the extended end of the closing and. Ejection spring behind his on the S _c hlicßriegel acting. End area is supported at least at one point on 2r> ilfj (V -: Schic sos or danit connected parts.

The lock for seat belts shown in the figures consists of a base body 1 designed as a corner profile, a lock bolt 2 that can be displaced transversely to the profile axis, with a Rxegelansatz 3 engaging in the profile cavity and a pushbutton ^£ !.

The base body 1 is connected to a fitting part 5 to be fastened to a vehicle via a bolt (not shown) tied together.

In the end of the base body 1 opposite the insertion opening 6 of the plug-in tongue 7 there is mounted a cinarnig eject lever 3 with bearing pin 9, which is designed as a bearing for a closing and ejection spring 1o designed as a spiral spring, the Ulli HiJL'etJl i-Llici'tiij. i <iiu.c 1 ι α. ti Kju-ittU W ^ iXiuu it- s ^ u ^ j ^ -. ^ ₀ ^ _ - · _λ ^. ^.
