Abstract
The barrel comprises a pre-stressed spiral spring which arms the barrel and further comprises a housing (100), a rotatable hub (200) and the spring (300) which is wound around the hub and anchored to the latter and to the housing. The barrel includes between the hub and the housing an anti-return device (400) which allows a relative rotation between the hub and the housing in only a single direction but is so arranged as to be movable between a first position in which it allows said relative rotation in only the single direction and a second position in which it allows rotation in both directions. The device is accessible from outside the housing for the purpose of shifting the device from one to the other of its positions. The barrel is particularly useful in ground motor vehicle safety belt winders.
