A seatbelt arrangement for a vehicle, comprising,
- a seatbelt and a plurality of connecting points arranged to connect the seatbelt to the vehicle,
- whereby a first connecting point is adapted to be placed at a position being at a first lateral side of a vehicle seat and proximate a seat portion of said vehicle seat, a second connecting point is adapted to be placed proximate the seat portion and at an opposite lateral side of the vehicle seat in respect of the first lateral side and a third connecting point is adapted to be placed at the first lateral side at a position above the first connecting point such that when the seatbelt is being used by a user of the vehicle seat, the seatbelt will extend transversely over a backrest of the vehicle seat from the third connecting point to the second connecting point, and from the second connecting point to the first connecting point over the seat portion,
- wherein said seatbelt is releasably connectable to the vehicle at the second connecting point,
- wherein said seatbelt arrangement further comprises a fourth connecting point for the seatbelt, wherein said fourth connecting point is adapted to be placed at the first lateral side of the vehicle seat and at an upper portion of the backrest, and
- wherein said fourth connecting point comprises a first buckle tongue being slidably connected to the seatbelt and a first buckle to be connected to the upper portion of the backrest, wherein said first buckle tongue is releasably connectable to the first buckle,
- a first detection means for detecting whether said first buckle tongue is connected to the first buckle at the fourth connecting point and a second detection means for detecting a parameter being indicative of an inclination angle of the backrest,
- wherein said seatbelt arrangement is configured to initiate a warning signal when the following conditions are fulfilled:
- the vehicle is moving, the first detection means detects that the first buckle tongue is disconnected from the first buckle and the second detection means detects that the inclination angle of the backrest has reached or exceeded a predefined threshold value.
