1. A safety belt retractor including a spool, a locking device for locking the spool and a vehicle sensing device for triggering a locking function of the locking device, wherein the vehicle sensing device has an adaptive vehicle sensing function,
wherein the safety belt retractor further includes vehicle sensing adaptivity suppression device for suppressing the adaptivity of the vehicle sensing function of the vehicle sensing device, and the vehicle sensing adaptivity suppression device includes a driven part and a suppression part,
wherein the driven part can be driven by the spool,
wherein the suppression part can be held on the driven part by an adhesive force, wherein the driven part has a sliding track, and the suppression part has a sliding portion that can slide on the sliding track against the adhesive force,
wherein the suppression part has a stop that can cooperate with a stationary counter stop, so that the suppression part can be limited in a first end position, and
wherein the suppression part has a retainer, and the vehicle sensing device has a counter retainer cooperating with the retainer, wherein the retainer and the counter retainer are disengaged when the suppression part is in the first end position, and the retainer and the counter retainer are engaged when the suppression part leaves away from the first end position to a predetermined extent, so that the adaptivity of the vehicle sensing function is locked.
