Abstract
Safety belt device (10) for a motor vehicle comprising: - a belt device (12) comprising a belt strap (14) and a retractor (16), wherein the retractor (16) is designed to retract the belt strap (14), and - a holding device (24) which is designed to support the belt device (12), wherein - the holding device (24) comprises a bearing (26) which is designed to permit a pivoting movement of the belt device (12) when a predetermined tensile force acts on the belt webbing (14) when the belt webbing (14) is pulled out; and - the safety belt device (10) further comprises an alignment device (32) which is designed to guide the belt device (16) during the pivoting movement of the belt device (16) by the predetermined tensile force acting on the belt webbing (14), characterized in that - the alignment device (32) comprises a plate-shaped element (36) and a guide element (40), wherein the plate-shaped element (36) comprises a receiving area (38), wherein the guide element (40) is arranged in the receiving area (38) and is coupled to the belt device (12), wherein the guide element (40) is guided in the receiving area (38) during the movement of the belt device (12), wherein the guide element (40) is connected to the holding device (24), wherein the receiving area (38) is designed as a tapered groove or as a tapered elongated hole.
