An adjuster device for a deflector fitting of a vehicular seat belt system comprises a first cable (28) connected to a longitudinally adjustable vehicle seat and guided to the circumference of a first pulley (26) and a second cable (18) connected to the deflector fitting and guided to the circumference of a second pulley (24). The pulleys (24, 26) are tensioned one against the other by a spiral spring (36) and coupled to rotate with respect to each other so that overloading of all and any of the components of the adjuster device is avoided.

Adjuster device for a deflector fitting

In a device for height adjustment of a vehicular seat belt fitting a load-supporting guide rail (10) equipped for securing to the vehicle has a plurality of latching members (21) spaced in its longitudinal direction. In this guide rail (10) a carrier (12) is shiftably mounted, to which the seat belt fitting is secured. A latch bar (22) selectively latchable to the latching members (21) in this guide rail is mounted on the carrier. By the actuation of a release member (26) the latch bar (22) is releasable from the corresponding latching member (21). The latch bar (22) is mounted on the carrier (12) so that it can be swivelled about a swivel axis (A) which is at least more or less horizontal and its center of gravity (S) is displaced in the direction of the guide rail (10) relative to a plane (E) oriented parallel to the guide rail (10) and passing through the swivel axis (A). In the case of a sudden downwards movement of the carrier 12 due to a belt tensioning action, the latch bar (22) is displaced into its latching position due to its own inertia.
