Abstract: A retractor for safety belts having a winding shaft acted upon by a retracting spring, and journaled in a housing so as to be non-displaceable axially, a detent disk provided with detent elements distributed over its periphery and fixed to the winding shaft, and a counter-detent member anti-rotationally joined to the housing and having at least one counter-detent element. The detent disk is disposed fixedly in the axial direction on the winding shaft while the counter-detent disk is axially displaceable on the winding shaft between the detent disk and a housing wall and is secured against rotation by lugs extending from the housing wall approximately parallel to the winding shaft towards the detent disk and engaging notches in the counter-detent disk. A spring extends between the counter-detent disk and the housing wall. A pushbutton displaceable axially to the winding shaft serves as actuating member for the counter-detent disk and grips the same.

Abstract: A push button lock for a safety belt is described including a first lock part which has an insertion aperture at one end, and a second slide in tongue part which is insertable into the opening in an axially extending plane of the first part. Within the first part there is a receiving housing which includes a web portion with a side wall on each side edge of the web portion which latter has a fixed stop which is engageable on a transverse edge formed on the tongue.A slot is provided in each side wall of the receiving housing and this has a first part which is parallel to the axial plane and a second part inclined with respect thereto. The housing has a push button which is axially slideable therein and this comprises a cross-bar, two side walls which are spaced apart by the cross-bar and a manually actuable portion at the insertion opening end of the lock part.
