The present disclosure relates to a method for operation of a safety arrangement (1) in a vehicle (3). The safety arrangement comprises a seat belt (9), a seat belt retractor (13) and at least one seat position adjustment arrangement (15, 29) for position adjustment of a seat (5) of the vehicle and/or a portion (23) of the seat. The operation of the safety arrangement comprises a retraction (110) of the seat belt by means of the seat belt retractor with a retraction force (130), and a pre-crash displacement (120) of the seat and/or the portion of the seat resulting in a displacement force (140) acting on the seat belt. The method comprises adapting the pre-crash displacement and the retraction of the seat belt to each other by ascertaining that a combined seat belt force (150) comprising the retraction force and the displacement force does not exceed a selectable level (160). The disclosure further relates to a safety arrangement for a vehicle and a vehicle comprising such a safety arrangement.
