DEVICE FOR TIGHTENING A SEAT BELT

摘要

A device for tightening a seat belt (1) such as, for example, a three-point seat belt comprising a lap belt part (2) and a diagonal belt part (3), where the seat belt is used to fix a child car seat in a passenger seat. A portion of the seat belt preferably the lap belt part (2) is arranged in connection with the child car seat's lower portion (4). The device is characterised in that the lower portion (4) is designed with an abutment portion (4a) for placing a portion of the seat belt, preferably the lap belt part (2). Furthermore, a tightening unit (5) is rotatably mounted in at least one mounting point (6) in connection with the child car seat's lower portion (4). The lap belt part (2) is arranged in such manner that it abuts against portions of the abutment portion (4a) and the tightening unit (5) when the tightening unit (5) is located in an initial position. The tightening unit (5) is brought into a tightening position by rotating the tightening unit (5) about the mounting point (6), thus causing the distance between portions of the lap belt part (2) and the child car seat's lower portion (4) to increase, while contact is maintained between portions of the lap belt part (2) and the tightening unit (5). A tightening is thereby obtained of the lap belt part (2) and the child car seat is thereby pressed further in towards the passenger seat.
