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： The pretensioner transmits power from a power source (rotary actuator A) to a belt take-up element through a clutch mechanism C. The latter has a driving rotary member 1 connected to the power source, a driven rotary member 2 connected to the belt take-up element, and engagement means 3 interposed between the two members. A follower rotary member 4 provided with rotational resistance is disposed in between the driving rotary member and the driven rotary member. Recesses are respectively formed in the driving rotary member and the follower rotary member to define a space for fully accommodating the engagement means 3. However, the latter are pushed out to contact and drive the driven rotary member by contraction of the accommodating space when a rotational phase difference between the driving rotary member and the follower rotary member occurs in response to an emergency situation. In an alternative arrangement, Figs. 8 to 13 (not shown), the engagement means comprise a number of pawls (3A) and the driven rotary member is a ratchet wheel (2A).

摘要： Rotary Actuator-operated Seat Belt Pretensioner A rotary actuator-operated seat belt pretensioner comprises a frame, a belt take-up shaft rotatably mounted on the frame, and a rotary actuator mounted on the frame and including a pressure chamber, a rotating member and a gas generator for supplying pressurized gas to the pressure chamber to impart rotation to the rotating member. A clutch is interposed between the rotating member and the take-up shaft. The pressure chamber of the actuator is annular and includes an inner wall defining a space within the chamber, and the clutch is received in the space within the chamber. The driving force of the rotating member produced by gas pressure supplied to the pressure chamber is transmitted to the take-up shaft by the clutch, and rotation of the take-up shaft winds a segment of the belt onto the shaft and thereby tightens the belt.

摘要： A retractor shaft-rotating type seat belt pretensioner for imparting pretension to a seat belt by rotating the take-up shaft of a belt retractor comprises a driving member engageable with a driven member on the take-up shaft and a power source coupled to the driving member and adapted to rotate the driving member by applying an operating force to it at an operating point. A guide surface supports the driving member at a reaction support point against the reaction force due to a rotary moment applied to the driving member at an engaging point where the driving member engages the take-up reel, the reaction support point being on the opposite side of the engaging point from the operating point where the operating force of the power source acts on the driving member.

摘要： A seat belt pretensioner of the type which rotates the take-up shaft of a retractor in the belt-winding direction so as to wind a length of the belt onto the retractor reel includes a driven gear connected to the retractor take-up shaft and a driving gear connected to a power source, the driving gear normally being held in clearance from the driven gear in the set condition of the pretensioner and being displaced and rotated upon operation of the power source to engage it with the driven gear and to drive the driven gear in rotation. The teeth of one of the gears have addenda that diverge from the addendum circle in the direction of the root circle and in a direction with respect to the direction of rotation of the driving gear such as to facilitate movement of the driving gear into driving engagement with the driven gear in the event of a collision of the addenda of the two gears.

摘要： In a tension less seat belt in which when worn, a small degree of slack is introduced for the comfort of the wearer under normal travelling conditions, the tensionless mechanism is controlled by signals from means detecting repositioning of the seat, changes in the reclination of the seat back or the posture of the wearer. Upon detection of such changes, normal seat belt tension is commanded for a predetermined length of time, after the expiry of which, the tensionless state is resumed.

摘要： A seat belt system comprises a seat belt retractor 1 having a tensionless function to prevent take up of a seat belt, by allowing the wearer to take out a limited amount of slack, the belt then being held in this condition. An acceleration sensor is provided - see figs 6A and 6B, for sensing only a negative acceleration in the direction in which a vehicle is advanced, and a mechanism 17 for cancelling the tensionless function of the retractor in accordance with a signal received from the sensor. The sensor comprises a pendulum switch in which the pendulum 34 is spring biased to contact electrical contact 36 when no deceleration is occurring. When deceleration occurs, contact is broken against the force of spring 37, and the solenoid 17 (fig 1) is activated to disengage the tension relieving mechanism. The idea is that even under gentle braking, the passenger is reassured by feeling the belt tighten up.
