device and reel to and roll of a belt of a belt, for example

摘要

The rolling and unrolling mechanism is particularly for a safety belt, the latter being wound round a spool with flanges secured in the lengthwise direction between two fixed sidewalls of the housing. A tubular body encloses the shaft of the mechanism, and the belt end forms the connection between spool and shaft during rotation. To secure the shaft (21) in the lengthwise direction in relation to the housing, retainers (8, 23) are provided to position the spool (1) in relation to the shaft in the lengthwise direction, typically comprising a rib on the tubular spool body engaging in a recess in the shaft. The spool is of material elastic in the radical direction, so as to snap the rib into the recess.
