A belt retractor unit with a housing, a rotatably mounted belt reel, a blocking unit for blocking the belt reel, wherein the blocking unit has an electrically controllable actuator unit, a control apparatus for controlling the actuator unit, which has a sensor apparatus for measuring at least one…
A system for securing a restraint system includes a retractor enclosing a spool, a sensor coupled to the spool, and a motor coupled to the spool and configured to rotate the spool about a spool rotation axis. The system also includes webbing configured to be wound and unwound from around the spool…
A belt retractor having an electrically actuatable locking device comprising a housing with a base plate and an upright first limb, a locking lever mounted pivotably on the upright first limb with a steel plate which is spring-loaded, and an electromagnet arranged in the housing and having a coil…
The application relates to a seatbelt retractor comprising a motor (8), a spool (4), a power transmission route (10-18) between the motor (8) and the spool (4), a switching mechanism (21-23) for connecting and disconnecting the power transmission route (10-18) and a ratchet mechanism (14,24-28)…
The belt retractor includes a drive wheel (22) that is rotatable relative to a belt spool (12) to a limited extent. The operation of a locking catch (46) is controlled as a function of the relative rotation of the drive wheel and belt spool.
A seat belt control device (1) is provided which comprises a drive motor (70) connected to a seat belt (2) for winding and unwinding the seat belt, a controller (10) for controlling the drive motor, a wearing state sensor (50) for detecting a wearing state of the seat belt (2), a vehicle speed…
According to the present invention there is provided a retractor (1) comprising a rotatably mounted spool (3) for supporting seat belt webbing, an emergency locking mechanism for selectively locking the spool (3) against rotation, an automatic locking mechanism for selectively locking the spool…
The object is to provide a seatbelt retractor in which a locking mechanism can be rapidly operated upon occurrence of an emergency without giving sensation of pressure to a vehicle occupant in a normal state. A reduction gear (13) and sun gear (13b) are integrally rotated by rotation of a motor…
The method involves detecting the direction of rotation of the belt shaft (12) when it is turning and setting the current supplied to the electric motor (14) from a first value to a second value different from the first value so as to compensate for hysteresis forces according to the detected…
The belt retractor for a passenger restraint system has a frame, a belt spool (18) rotatably mounted in the frame, and a locking mechanism (24, 30) for selective blocking of the belt spool. A locking gear (24) provided with external teeth is attached to a flange (22) of the belt spool. A pawl (30)…
