OPERATIONAL DESCRIPTION
Seat Belt Stored Condition-7When Pulling Out
Since the memory tape is wound up, the bushing
shaft and tape holder turn as one unit. The torque of
the two springs, the reducing spring and normal

When the webbing is pulled out and the tongue set in
the buckle with the ignition switch in the ON position,
the switch inside the buckle is turned ON, the
solenoid functions and the lever meshes with the
outer teeth of the tape holder. As a result, the tape
holder is locked in the winding direction, torque of the
normal spring falls to zero and the winding torque
becomes only the torque of the reducing spring.
Consequently, the feeling of oppression is reduced
when the seat belt is initially buckled up and when it

remains buckles. Furthermore, since the tape holder
is locked, the memory tape is loosened by the
rotation of the bushing shaft in accordance with the
winding of the reducing spring. The amount of
loosening of the memory tape is the difference in the
elongation ratio of the normal spring and reducing
spring, and this serves to make the elongation ratio of
the 2 springs the same when the seat belt is stored.
