Abstract

A latch mechanism for safety belts of the roller belt type intended preferably for vehicles and comprising a strap (3) which can be withdrawn from a roll-up mechanism (1) against spring bias. This roll-up mechanism includes a strap roller(2) rotatably mounted therein, a latch mechanism (8) with a ratchet (10) and a latch (9) which can be adjusted between a position releasing the strap roller, and a latching position. An activating means (7) is arranged for adjusting the latch mechanism to the latching position when the activating means is exposed to an acceleration exceeding a predetermined value. An inertia body included into the activating means is supported in the central rest position thereof by a support surface (24) on the transmission element, and a second support surface (17) is located in a space (15) in which the inertia body is located. A transmission element operatively arranged between the inertia body and the latch has a sensing portion (27) which is located in the cavity (26) of the inertia body, spaced from the first support surface (24), and is arranged to be displaced together with the transmission element and then to turn this element about an annular marginal portion (18) of said second support surface by an engagement surface or edge (28) in the cavity (26) of the inertia body being brought to engage the sensing portion. The latch comprises an operating portion (30) having the shape of a bowl turned up and down with a concave operating surface (31) angled in relation to the longitudinal direction of the transmission element. An activating portion (29) of the transmission element is arranged to project into the operating portion and to turn when the inertia body turns and to be displaced at said turning along the operating surface, the latch being adjusted from releasing position to latching position thereby.
