<p>1. An automatic rapid-lock inertia safety belt mechanism comprising a main housing (14), a roll-up spindle (2) with an associated roll-up spring and a rolled-up safety belt (1) and also a locking mechanism, consisting of an inertia force sensor (8, 9), a locking catch (4) disposed for movement by means of a retaining stud (4b) mounted in a retaining bore (14b) in the housing (14), a locking gearwheel (3) and, carrying the inertia force sensor (8, 9) and mounted on the housing concentrically of the roll-up spindle (2) with a control element (5) freely rotatable in respect of the roll-up spindle (2) and with internally cut teeth (5d) for controlling the locking catch (4) via a control cam (5a) to engage the locking gearwheel (3), with a control gearwheel (6) having externally cut teeth (6c), connected to the roll-up spindle (2) and mounting the control element (5), and with a freely rotatably mounted control catch (10) which is mounted (10a) on the control gearwheel (6) and which has a long lever (10e) and a short lever (10f), and with, adapted to be brought into engagement with the ends (10b, 10c) of the control catch (10) via projections (7b, 7c), a rotatable mass of inertia (7) for actuating the locking catch (4) when there is an excessive acceleration of the safety belt, characterised in that the control gearwheel (6) is fixed on the locking gearwheel (3) via eccentric studs (6e) and comprises a hollow central stud (16) projecting towards the opposite side and in which the central pin of the cup-shaped control element (5) is rotatably mounted, engaging like a cup around the locking gearwheel (3), the locking catch (4) and the control gearwheel (6) with the rotary inertia mass (7) and control catch (10) mounted therein and in that the retaining bore (14b) in the housing (14) is brought into alignment with the belt intake and outlet passage (23) and in that in the locked condition, the region of the locking catch teeth is outside of or at the end (24) of the belt intake and outlet passage (23) on the side towards the locking gearwheel (3).</p> |
