초록 ▼

A rotatable spool has seat belt webbing wound around the spool. A motor, when actuated, rotates the spool in the belt withdrawal direction. A spring has a biasing force which rotates the spool to wind the belt webbing onto the spool. A worm gear mechanism is located between the motor and the spool and is selectively drivingly connectable with the spool. When drivingly connected with the spool, the worm gear mechanism prevents the biasing force of the spring from winding the belt webbing onto the spool. A clutch, when engaged, connects the spool and the worm gear mechanism. The clutch is disengaged and the motor is deactuated when a belt tension signal is below a lower predetermined threshold value. The clutch is engaged and the motor is actuated when the belt tension signal is above an upper predetermined threshold value which is greater than the lower predetermined threshold value. The clutch is engaged and the motor is deactuated when the belt tension signal is between the upper and lower predetermined threshold values. A pressure sensor provides the belt tension signal which continuously varies in magnitude as the amount of tension in the belt webbing continuously varies.

대표청구항 ▼

An apparatus comprising: a belt webbing extendable around a vehicle occupant in a seat, said belt webbing having a generally V-shaped portion including a pair of webbing lengths and a base portion interconnecting said pair of webbing lengths; a rotatable spool with said belt webbing wound around said spool, said spool being rotatable in a belt withdrawal direction and in a belt retraction direction, said spool being rotatable in the belt withdrawal direction to enable said belt webbing to be unwound from said spool and buckled around a vehicle occupant, said spool being rotatable in the belt retraction direction to enable said belt webbing to be wound on said spool and drawn against the occupant; an actuatable motor for, when actuated, rotating said spool in the belt withdrawal direction; a belt turning loop assembly including a belt webbing guide member having an opening through which said base portion of said belt webbing extends, said belt webbing guide member including a rib which said base portion of said belt webbing presses against when tension is applied to said belt webbing; means for sensing force applied to said rib by said base portion of said V-shaped portion of said belt webbing, said means comprising (i) a surface portion of said rib, and (ii) a pressure-sensitive chip against which said surface portion of said rib presses when force is applied to said rib by said base portion of said V-shaped portion of said belt webbing, said pressure-sensitive chip including means for providing an analog electrical signal having a magnitude which varies in response to pressure applied by said surface portion of said rib to said chip and which is indicative of the amount of tension applied to said belt webbing; and controller means for controlling actuation of said motor in response to the magnitude of said signal exceeding a predetermined threshold value and thereby controlling rotation of said spool in the belt withdrawal direction.
