摘要： A rotary actuator 1 is driven in rotation by pressurized gas supplied by a gas generator 2 and drives a belt take-up reel (R9, Fig 2). A partition wall 112 that separates the pressure section 102A of the operating chamber 102 from the exhaust section 102B receives a seal member 13, which is resiliently urged by a spring 14 into engagement with the body portion (122, Fig 3) of rotor 12. The seal member prevents gas from leaking past the partition wall from the pressure section to the exhaust section.

摘要： A mechanical acceleration sensor having a weight movably supported on a casing, a latch lever loaded with a set load and disposed to face the weight, and a firing pin spring-loaded and engaged with the latch lever. The latch lever is disengaged from the firing pin against the set load by inertial movement of the weight relative to the casing, thereby allowing the firing pin to perform a percussive action. A sub-lever is provided in connection with the latch lever. The sub-lever is disposed to face a side of the weight which is opposite to the side thereof that faces the latch lever so as to cooperate with the latch lever to clamp the weight from both sides of the direction of inertial movement of the weight, thereby making it possible to sense acceleration acting on the sensor in both the positive and negative directions of inertial movement of the weight by the inertial movement thereof.

摘要： A seat belt retractor is formed of a reel for a seat belt having a rotary shaft with an end, a bearing for rotationally supporting the end of the rotary shaft, and a rotary shaft end support formed in the bearing. The end of the rotary shaft has a curved surface, and the rotary shaft end support has an opposing surface opposing the end of the rotary shaft for supporting the end of the rotary shaft. The opposing surface has a curved surface corresponding to that of the end of the rotary shaft to thereby properly support the rotary shaft without wobbling.

摘要： The belt retraction system comprises of a reel (4) to wind-up a belt (3), a locking mechanism (6) to prevent turning of the reel in unwinding direction, and a torsion bar (7), for non-turnable connection of reel and locking mechanism. The torsion bar has a torsion part (20), which is twisted when turning of the reel in that direction is being stopped by the mechanism, so that energy is absorbed. The hardness in the outer section of the torsion part is set, so that it is lower than the hardness in the central section of the torsion part.

摘要： A mechanical igniter for a gas generator has a weight, a latch lever and a firing pin as movable elements to fire a percussion cap attached to the gas generator in response to acceleration, and further has a restraint member and a controller therefor as a safety device for making the movable elements immovable. The controller can be activated by attaching the mechanical igniter to the vehicle body, or removing a belt stopper after the mechanical igniter has been attached to the vehicle body, or fastening a seat belt to the occupant's body. Thus, the restraint member is released when the mechanical igniter is attached to the vehicle body, or when the seat belt system is used, thereby automatically and safely releasing the safety device for the igniter.

摘要： A mechanical igniter for a gas generator has a weight, a latch lever and a firing pin, which are provided in a casing as movable elements to fire a percussion cap attached to the gas generator in response to acceleration. The mechanical igniter further has a restraint member movably supported in the casing as a safety catch for making the movable elements immovable. The casing and the restraint member are respectively formed with cam surfaces which cooperate with each other to rotate the restraint member about its own axis so that the restraint member is selectively set in a restraint position and a release position. The restraint member has a rotary control portion that is concealed in the casing and has a portion that is engageable by a rotary tightening tool, such as used in an ordinary bolt tightening operation or the like. The restraint member is rotated by engaging the rotary tightening tool with the rotary control portion of the restraint member and turning the tool. As a result of the rotation, the restraint member is displaced from the restraint position to the release position and set in the latter position by the cooperation of the cam surfaces. Thus, the movable elements are released from the immovable state, thereby allowing the igniter to fire the percussion cap in response to acceleration.

摘要： A gas-pressure actuator apparatus having a rotary actuator serving as a driving source for a pretensioner of a seatbelt system, and a gas generator for supplying a working gas to the actuator. The rotary actuator includes a cylinder block and a rotary piston. The cylinder block has a cylinder chamber, a preliminary chamber formed adjacent to the cylinder chamber, and a communicating hole for providing communication between the cylinder and preliminary chambers. The gas generator is attached to the cylinder block in such a manner that a gas outlet for releasing the generated gas opens into the preliminary chamber. The preliminary chamber functions as a gas pressure buffer space for the cylinder chamber and also serves as a capacity element as follows: In the early stage of the rotary piston operation where the volumetric capacity of the pressurizing chamber defined in the cylinder chamber is extremely small, the preliminary chamber lowers the gas pressure applied to the rotary piston. On the other hand, in a state where the volumetric capacity of the pressurizing chamber has become large at the end of the rotary piston operation, the preliminary chamber raises the gas pressure applied to the rotary piston.

摘要： A trigger for a spring-type pretensioner providing pretension to a vehicle seat belt upon release of a preloaded spring comprises a first toggle and a second toggle connected to the first toggle. The first toggle is engaged with the operating end of a spring, and the second toggle is connected to an output member for transmitting sensor output. The first toggle supports the spring load while it is beyond its toggle dead point, and the second toggle engages the first toggle while it is not beyond its toggle dead point and restricts the operation of said first toggle. The second toggle receives the sensor output and upon being moved thereby beyond its dead point releases the first toggle, whereupon the spring preload is released and the pretensioner is operated.
