Abstract [en]

The invention includes an arrangement related to seatbelts (1) adapted to a vehicle, having at all events two securing points (2a, 2b), intended for the belt, which points are related to a chassis (3a) belonging to the vehicle, at all events one of the securing points (2b) belonging to the belt consisting of a reel (40), drivable by an electric motor (4), in order to be able to reel belt sections or parts near the securing points (2d) thereon with an intention of being able to hold belt stretchings (2e, 2f) stretched against a person's chest and/or trunk portion or vice versa. One or more sensors are adapted to, at a value occurring above a selected limit value, let said electric motor (4) be activated to drive the reel (40) in a direction in order to increase the stretching force in said belt, and said electric motor consists of a polyphase motor. Said polyphase motor (4) is designed to present a low electric inductance and/or a high torque density, in order to thereby be able to provide a relatively high starting torque, high torque and endure high overload during intermittent operation conditions.
