Abstract

See full text

A retraction device includes a housing and a driving element guided in the housing between a parked position and an end position. A first end of a spring energy accumulator is connected to the housing. The spring energy accumulator is loaded to a maximum operating value when the driving element is in the parked position and is unloaded to a residual energy value when the driving element is in the end position. A second end of the spring energy accumulator can either be fixed to the housing or coupled to the driving element by means of a bistable coupling. The coupling has a blocking element that can be moved between the housing and the driving element.
