摘要： A spindle (2) of a seat belt retractor is rotationally driven when required by a motor (5) to the webbing take-up direction side through a power transmission mechanism section (6). Further, the spindle (2) is always connected to a take-up spring (7) and is always subjected to rotational power acting to the webbing take-up side. The structure enables a user wearing a seat belt to be restrained even in failure, realizing a safer and more reliable restraining device.

摘要： A retractor includes a slide nut that is caused to slide toward a tread head while rotating by a mesh between a first male screw groove and a female screw groove when the tread head is locked and a spindle rotates in a direction for unreeling a webbing, and a slider that is caused to slide toward the slide nut by a mesh between the female screw groove and a second male screw groove. A torsional rigidity of a second shaft part of a torsion bar is larger than that of a first shaft part, and a play is eliminated before a gap such that the slide nut and the slider are integrated.

摘要： A starting device (21, 121, 41) for actuating a gas generator (8) by striking a detonator (10) in response to an acceleration of a predetermined level or more. The starting device includes a firing pin (22), an inertial mass (23), an annular permanent magnet (24) and an erroneous-actuation preventing mechanism (9, 109, 42). The firing pin (22) is capable of igniting the detonator (10) by moving toward and colliding against the detonator (10). The inertial mass (23) is made of a cylindrical permanent magnet for supplying kinetic energy to the firing pin (22). The annular permanent magnet (24) has an inside diameter larger than an outside diameter of the inertial mass (23). The erroneous-actuation preventing mechanism (9,109, 42) prevents the erroneous actuation of the starting device (21, 121, 41). The erroneous-actuation preventing mechanism (9,109, 42) includes a restricting member for selectively setting the inertial mass (23) in a nonmovable state and in a movable state.

摘要： An automotive passenger restraint and protection apparatus prevents damage to a seatbelt. An electric retractor having a motor for retracting and protracting the seatbelt includes the automotive passenger restraint and protection apparatus. The motor is controlled by a CPU. The CPU detects whether the seatbelt is attached to, or disconnected from, the occupant, and whether the seatbelt has been retracted to a limit thereof. The motor is controlled by the CPU such that when the CPU detects that the seatbelt is retracted and when the CPU subsequently detects that the seatbelt has been fully retracted to the limit thereof, the seatbelt is prevented from being further retracted.

摘要： An automotive passenger restraint and protection apparatus for an automotive vehicle has a seatbelt and operates to restrain an occupant of the automotive vehicle by the seatbelt to protect the occupant. An electric retractor has a DC motor for retracting and protracting the seatbelt. An MPU controls the DC motor. Protraction of the seatbelt by the occupant is detected. When the protraction of said belt is detected, the MPU controls the DC motor so as to protract the seatbelt. A seatbelt protraction and retraction amount-detecting device calculates an amount of protraction or retraction of the seatbelt, based upon at least one of a number of times pulsating components of detected terminal voltage across the DC motor rises above a first predetermined value from a value below a first predetermined value, a number of times the pulsating components drops below a second predetermined value from a value above the second predetermined value, a frequency component obtained by frequency analysis of the pulsating components, and results of time integration of the detected terminal voltage, and a detected rotational direction of the motor.

摘要： In a through anchor (10), a webbing sliding contact surface (15) is formed by bending in a curved fashion a lower edge of an opening (14) formed in a metal insert (11) toward a side. The through anchor (10) is covered over portions of the metal insert (11) other than the webbing sliding contact surface (15) with a coating resin (13). Accordingly, it is possible to provide a seat belt assembly that can continue to provide good sliding contact between a webbing guide and webbing, with simple construction.
