摘要： An electric control system for an automobile transmission includes an endless transmission member running on a pair of V-shaped pulley units, the mutual distances of the conical sheaves of which are hydraulically adjustable to transmit an output torque of an engine to a driven apparatus. The electric control system is arranged to determine an optimum fluid pressure in relation to the actual output torque of the engine and to determine an optimum transmission ratio for low fuel consumption in relation to the actual output power of the engine. The control system produces a first electric control signal indicative of the difference between the optimum fluid pressure and the actual fluid pressure in one of actuators for the respective pulley units and produces a second electric control signal indicative of the difference between the optimum and actual transmission ratios. The pressure of fluid applied to one of the actuators is controlled in response to the first electric control signal, and the flow quantity of fluid applied to the other actuator is controlled in response to the second electric control signal.

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 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 high pressure gas container hermetically confining therein a high pressure gas for inflating instantaneously a safety air bag to protect occupants in a vehicle is provided with an improved discharge valve for blowing out the gas from the container. The discharge valve comprises a sealing disk disposed at a blocking cock portion, which disk has a thick center portion and thin peripheral portion so that the whole disk may be utterly ruptured upon explosion of a detonator disposed adjacent to the thicker portion of the sealing disk. Such complete destruction of the sealing disk will result in a formation of a large opening for blowing out the high pressure gas and hence allows a rapid inflation of the safety air bag due to increased flow rate of the jetted high pressure gas from the container.
