Working Diagram Operation
Basic Operating Process ▶
MGG is ignited and the piston moves up by the
gas pressure.
The rack gear is engaged to the piston. This
changes the linear movement to rotational
movement.
When the piston is rotating, the roller moves to
shaft according to the cam shape of pinion. At
this moment, the clutch is engaged.
The combined set of pinion, sleeve and spool
rotates as a set. -

-
The piston moves up by
the gas pressure and
pulls in the belt by
rotating the spool. -
If the shaft torsion starts to deformed due to
increased load to the passenger, the spool
and pinion (clutch assembly) rotates in reverse
and the psiton moves down.
The psiton moves down when the residual
pressure is eliminated through vent hole. If it
reaches to the bottom, the pinion is
disengaged and rotates freely. -
- Initial position 1.
Inflator ignited
(inner clutch
engaged) 2.
Piston moved to
top position 3.
Load limiter
operated (rack
moved to
opposite
direction) 4.
Rotation of sleeve Tha gap netween
roller and sleeve
is maintained.
Thus, the sleeve
transfers the reel
spring torque to
the spool when it
is rotated. -
