Abstract
A seat belt tensioning device for a vehicle comprises a fixed member fixed to a vehicle body, a movable member which is movable in the direction opposite to the fixed member, a bellow shaped flexible member, both ends of which are secured to the fixed member and the movable member to form a sealed chamber, a rod, one end of which is secured to the movable member, the other end of which is connected to a seat belt through the sealed chamber, and a guide member which is provided along the flexible member for guiding the elongation of the flexible member. One end of the guide member is airtightly fixed to the movable member and the other end of the guide member extends in the direction opposite to the movable member while airtightly and slidably contacted with the fixed member at an urgent time such as upon a vehicle impact, a high pressure gas is produced and is poured into the sealed chamber. Then, the flexible member which is usually contracted, is elongated due to the high gas pressure. Since the flexible member is connected to the guide member through the movable member, the guide member guides the elongation of the flexible member without generating any buckling deformation. Therefore, the seat belt which is connected to the movable member through the rod is certainly tensioned to restrain an occupant with safety.
