摘要： A cylinder-piston type seat belt tensioning device comprises a broach pipe wherein a broach rod which is connected to a seat belt is disposed, a load limiting member connecting the broach rod to the piston, which is broken at a predetermined load, and locking means for locking the broach pipe in the cylinder when the load limiting member is broken. After the load limiting member is broken at a predetermined load, the broach rod returns while plastically deforming the broach pipe to absorb the kinetic energy of the occupant.

摘要： A seat belt retractor to be installed in a seat belt system of a vehicle for restraining an occupant on his seat by a seat belt in an emergency, comprises a reel, a torsion bar, one end of which is connected to the reel so as to be rotated therewith, the other end of which is formed into a locking portion, a lock member to be engaged with the locking portion for locking the other end of the torsion bar in an emergency and a stopper means which is disposed between the reel and the torsion bar for stopping the rotation of the reel. In an emergency such as upon an impact of the vehicle, the lock member operates to lock the other end of the torsion bar. The torsion bar of which one end is connected to the rotating reel is twisted to absorb the impact energy of an occupant. And before the torsion bar is broken, the stopper means operates to stop the rotation of the reel. Therefore, even if a large tension force is applied to the seat belt, the torsion bar is not broken due to the twisting thereof.

摘要： A tensioning device for a seat belt for protecting a passenger at an urgent time by restraining him on his seat by a tensioned seat belt. A base is adapted to be fixed to a vehicle, and spaced from the base is a plate to which is connected one end of a seat belt which itself is movably inserted through the central portion of the base. At least one flexible cylindrical body is connected between the base and the plate to form a sealed chamber. The cylindrical body is normally in a contracted state, and a gas supplying means which supplies a high pressure gas at an urgent time into the sealed chamber elongates the contracted cylindrical body into a flat sheet to tension the seat belt and restrain the passenger on his seat.

摘要： A seat belt tensioning device includes a cylinder and a piston, one fixed to a vehicle and the other to a seat belt. Means are provided for operating the cylinder, on impact, to retract a piston rod and tension the belt. The piston rod is provided with a load limiting portion to be broken when the tension load of the seat belt reaches a predetermined value. Means are provided for locking the piston in the cylinder when the load limiting portion is broken. A second rod connects the seat belt and the piston when the load limiting portion is broken. The second rod is provided with a plastically deformable portion in contact with the piston. When the tension force of the seat belt applied to the piston through the second rod increases, the plastically deformable portion is deformed to absorb the kinetic energy of the passenger.

摘要： 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.

摘要： An energy absorbing device for use with a vehicular seat belt includes a housing adapted to be secured to the vehicle and defines a circular interior space and a narrow passage extending between the interior space and the outer surface of the housing. An elongated rod-like strip of a metal has a coiled end portion having a plurality of turns disposed in the circular space. An intermediate portion of the metal strip extends from the interior space outwardly through the narrow passage and terminates in the other end which is adapted to be connected to the seat belt. The junction between the circular space and the narrow passage is shaped to bend successive portions of the metal strip and guide them into the narrow passage when a tension of a magnitude greater than the bending stress of the metal strip is applied to the outer end of the strip during a collision.

摘要： A safety seat-belt retractor for use in vehicles, comprising a fixed frame, a winding shaft rotatably mounted on the frame, and a toothed member mounted on the shaft for relative rotation thereto. A pawl is operative in response to a predetermined deceleration of a vehicle to lock the toothed member against rotation relative to the frame. A first projection and a second annular projection are formed on an axial end face of the toothed wheel with the first projection radially spaced from and positioned between the second annular projection and the shaft. An elongated energy-absorption member has one end thereof secured to the shaft and the other end free and extends between the shaft and the first projection, around the latter in U-shape and between the first and second projections. The elongated energy-absorption member is forcedly drawn by and wound around the shaft to absorb a tension on the seat-belt when the toothed member is locked by the pawl.

摘要： A seat belt system for a vehicle including an impact energy absorbing device mounted between a seat belt for restraining an occupant and a seat belt anchor means. The impact energy absorbing device includes a cutter, a member disposed in juxtaposed relation to the cutter and adapted to be sheared by the cutter as the member and the cutter move relative to each other, and a cutter supporting member to which the cutter is securely fixed. When the vehicle collides, the impact energy is absorbed by the shearing of the member by the cutter. The shearing load exerted on the member may vary depending on the tension speed exerted on the seat belt at the time of collision, so that the movement of the occupant caused by the collision can be confined to a substantially constant range at varying collision velocities and a secondary collision of the occupant against an instrument panel or the like can be prevented.

摘要： A piston return stop device for seat belt tensioning equipment. Connected at one end to a seat belt through a cylinder is a piston having a tapered portion the diameter of which enlarges toward its other end. A cylindrical sliding member is slidably disposed between the cylinder and piston so as to slide together with the piston when the piston is thrust to tension the seat belt. A respective stopper member is slidably disposed within each guide groove radially perforated through the cylindrical sliding member and supported by the tapered portion of the piston.When the piston is thrust through the cylinder at an urgent time until the tension force of the seat belt reaches a predetermined value, the piston is stopped from moving within the cylinder furthermore and only the cylindrical sliding member slides within the cylinder due to its inertia force together with the stopper members. Then the stopper member is pushed up by the tapered portion of the piston to cut into the inner wall of the piston. As a result, the return of the piston is certainly and safely stopped.
