Abstract: A vehicle seat with a seat cushion, adjustably fixed to the floor of the vehicle, and a backrest, which can be adjusted with respect to the seat cushion, is provided with a restraining device for the seat user. The restraint comprises a three-point safety belt and an additional belt. For optimum protection of the seat user in the resting position and also to prevent so-called submarining, a fixed adjustment of seat cushion and backrest is provided in the resting position in such a manner that the backrest is swiveled about an obtuse angle with respect to the seat cushion, and the seat cushion is shifted into a predetermined front position in the driving direction and inclined towards the rear. The additional belt extends as a transverse shoulder belt from the upper edge of the backrest to a belt buckle disposed near the floor.
