Safety belt arrangement for occupants of land vehicles and aircraft
First Claim
1. In a safety belt arrangement, for use in land vehicles and aircraft for securing the occupants thereof, including at least one belt-reeling device with a self-locking blocking mechanism with control means for activating a blocking position that prevents the belt from being pulled out further, the improvement wherein:
- an on-board computer is provided for determining acceleration and deceleration forces of said vehicle and aircraft by calculating said acceleration and deceleration forces by taking values based on operating commands, so that for movements of said vehicle and aircraft initiated by an operator said acceleration and deceleration forces are calculated before actually occurring and can be used as measurements for controlling said self-locking blocking mechanism, with said on-board computer being coupled to said control means of said belt reeling device, said control means activating said blocking position and returning said blocking mechanism to a rest position in response to a signal produced by said on-board computer based on said measurements.

Abstract
A safety belt arrangement, for use in land vehicles or aircraft for securing the occupants thereof, has at least one belt reeling device with a self-locking blocking mechanism with a mechanical control for moving a locking member into the blocking position which prevents the belt from being pulled out further. In order to reduce the response times for the belt reeling devices, a computer is provided which determines the acceleration characteristics of the particular vehicle or aircraft and is coupled to the mechanical control of the belt reeling device, the locking member being moved into its blocking position or returned to its rest position by the mechanical control in response to a signal emitted by the computer.
