Lock Mechanism
With this mechanism connectors (male and female
connectors) are locked by 2 locking devices to in-
crease connection reliability. If the primary lock is in-
complete, ribs interfere and prevent the secondary
lock.
(b)
When the vehicle is involved in a frontal collision in the
hatched area (Fig. 1) and the shock is larger than the pre-
determined level, the SRS is activated automatically. A
safing sensor is designed to go on at a smaller decelera-
tion rate than the airbag sensor. As illustrated in Fig. 2,
ignition is caused when current flows to the squib, which
happens when a safing sensor and the airbag sensor go
on simultaneously.When a deceleration force acts on the
sensors, two squibs in the driver airbag and front passen-
ger airbag ignite and generate gas. The gas discharging
into the driver airbag and front passenger airbag rapidly
increases the pressure inside the bags, breaking open
the steering wheel pad and instrument panel door.
Bag inflation then ends, and the bags deflate as the gas
is discharged through discharge holes at the bag’s rear or
side.
