To provide a highly refractory rubber composition sheet that retains a fixed shape until the thermal expansion residue formed by the heat of a fire or the like is formed, does not allow the thermal expansion residue from the heat formed by a fire or the like to easily detach and fall off of construction materials, such as steel framing and the like, and can prevent penetration of flames for at least two hours in the case of exposure to the flames of a fire or the like. [Solution] The highly refractory rubber composition sheet is formed from a highly refractory rubber composition that contains a polyhydric alcohol (A), a nitrogen-containing foaming agent (B), a rubber substance (C), a flame resistant foaming agent (D), and titanium dioxide (E). The highly refractory rubber composition sheet is characterized by the nitrogen-containing foaming agent (B), being in a range of 76-80 parts by weight to 100 parts by weight of the rubber substance (C).

A method of protecting a passenger in a vehicle from a series of collisions. The method includes detecting that the vehicle is in danger of being involved in a first collision; winding up a webbing of a seat belt to restrain the passenger; permitting the passenger to move forward and the webbing to withdraw; winding up the webbing to restrain and return the passenger to a normal seated position; maintaining the passenger in a restrained condition; determining that the vehicle is in danger of being involved in a second collision; permitting the passenger to move forward and the webbing to withdraw; winding up the webbing to restrain the passenger and return the passenger to a normal seated position; maintaining the passenger in a restrained position; and releasing the restraint on the passenger.

A pretensioner mechanism for a vehicle seat belt comprises a loading device for applying a preload to the seat belt by pulling a segment of the belt in a direction transverse to a path along which is normally extends. The loading device includes a pulling member having a portion engageable with the belt segment and rotatable about an axis spaced apart from and oriented transversely to said normal path of the belt segment. A one-way clamp engages the belt and substantially prevents release of the applied preload. An interlocking device between the loading device and the clamp operates the clamp in response to movement of the pulling member in a direction opposite to the direction in which it moves to apply the preload to the belt.

In an optical pickup apparatus comprising a light source for applying a light beam to an optical memory medium, a beam splitter disposed in the optical path from the light source to the medium to separate the reflected beam from the medium from the beam from the light source, and a photodetector for detecting the separated reflected beam, having a surface opposed to that surface of the beam splitter which faces the photodetector is formed so as to form an angle different from the perpendicular with respect to the optic axis of the separated reflected beam.

An optical information processing apparatus comprising record/reproduction devices for irradiating a focused light beam onto a track on a record medium to record or reproduce information tracking control devices for precisely directing the irradiated light beam to the track split devices for splitting at least a portion of a reflected or transmitted light beam of the irradiated light beam from the record medium into two light beams first screen devices for screening a center area of one of the split light beams across a width of the track second screen devices for screening a peripheral area of the other of the split light beams across the width of the track and detection devices for comparing light intensities of the two light beams transmitted without being screened by said first and second screen devices to detect a focusing state of the irradiated light beam to the record medium.

A motorized seat belt retractor configured to be activated in response to a signal generated by a dangerous state detection device indicating that a vehicle is in a dangerous state. The retractor is configured so that in response to the signal the retractor operates to retract a seat belt webbing prior to a collision thereby restraining an occupant positioned in a seat in the vehicle. The retractor is activated every time a signal indicating that the vehicle is in a dangerous state is received from the detector.

A seat belt retractor having a function of taking up a seat belt using a motor. A spool is fitted in a base frame such that a torsion bar functions as a shaft of the spool. Two gear-clutch casings are disposed on the left and right sides of the spool via a pretensioner and a locking mechanism, respectively, wherein two motors are disposed to the gear-clutch casings, respectively. The two motors achieve respective functions which are different from each other and rotate at respective constant speeds.

A seat belt retractor is formed of a frame, a reel rotationally supported by the frame for winding a seat belt, a reel urging device connected to the reel for urging the reel in a seat belt winding direction, a locking device provided between the frame and the reel for allowing the reel to rotate freely in a normal state and preventing the reel to rotate in a belt unwinding direction when necessary, and a belt tension control mechanism for controlling a belt tension of the seat belt. The belt tension control mechanism includes a motor, and a power transmission path situated between the motor and the reel and actuated by the motor. The power transmission path has an OFF-state in which a rotational torque of the motor is not transmitted between the motor and the reel, and an ON-state in which the rotational torque is transmitted between the motor and the reel. A power transmission path switching mechanism selectively switches the power transmission path between the ON-state and the OFF-state. The belt tension control mechanism is simplified by reducing the number of the components.

A seat belt tension adjuster adjusts tension on a seat belt wound on a reel by a biasing spring. The tension adjuster includes a biasing force adjusting mechanism situated between the reel and the spring for adjusting a biasing force transmitted from the spring to the reel depending on a rotational angular position of the reel. The biasing force adjusting mechanism includes a cam for gradually changing the biasing force based on the rotational angular position of the reel. The tension adjuster can freely set the withdrawing force and the winding force of the seat belt.

In a seat belt control device of the invention, when a buckle switch detects disengagement of a buckle and a tongue plate of a seat belt, the seat belt is retracted through a motor. In addition, the seat belt is re-retracted, through a motor, when a passenger detector detects that no passenger is present in an automobile, when a door switch detects that a door opens, or when an engine key switch detects that an engine key is pulled out or is in an off state. Thus, the seat belt can be positively retracted. Therefore, when a passenger gets off or is going to get off, the seat belt can be securely retracted to thereby prevent the seat belt from being caught by a projection in a compartment or by the door of the automobile.
