Abstract
A spring (10), for a locking device of a vehicle seat, is designed as a yoke spring defining an axis (A) and made of a spring wire. A cross section diameter (q) has one leg (10a) on each of both ends of the spring wire. The two legs (10a) can pivot relative to each other in a circumferential direction of the axis (A), thereby transitioning the spring (10) from a relaxed state into a tensioned state. At least one first winding (10b) is provided between the legs (10a) that is wound completely around the axis (A) and having a winding diameter (di) in the relaxed state. At least one adjacent second winding (10b) is provided between the legs (10a) and disposed offset along by the axis (A) by a pitch (h), wherein the second winding (10b) may optionally be wound not fully about the axis (A). The second winding (10b) has a winding diameter (d2) in the relaxed state. The pitch (h) is less than the cross section diameter (q).
