Abstract

The automatic release mechanism for car or aircraft safety belt can be inserted at any point in the belt. The housing consists of two parts (6, 10) and is detachably fixed to a connecting cap (2). The housing incorporates a pyrotechnic capsule (14). Holes (18) inside the cap (2) contain balls (4) held in position by an axial plunger (3). The housing has an inside notch in enabling the balls to escape when the connecting piece (9) slides along the slide piece formed by the notch. The housing has a projection (19) fitting into the cap (2).
