Webbing retractor.
Background technique
Latch functions on automobile safety belt retractor can guarantee that vehicle encounters safety belt under fortuitous event and is not drawn out,
To protect occupant.But latch functions can cause safety belt in normal use process by false triggering in many cases
It is locked up, causes safety belt that can not pull out.When being in slope such as vehicle, the latch functions of safety belt can be triggered, and lead to occupant
It is used after getting on the bus on the slope without pull-out safety belt；The seat belt retractor of back seat is mounted on by back, works as back seat
After toppling over certain angle, the latch functions of safety belt can be triggered, and occupant is caused to use without safety belt is pulled out；Occupant sits on the seat
Afterwards, if occupant pulls out the excessive velocities (greater than the upper limit value of coiler locking setting) of ribbon, the locking of safety belt is also resulted in
Function triggering, safety belt are used without safety belt is pulled out.Above situation is all the normal operating condition of safety belt, but safety belt is rolled up
The latch functions of device are received by false triggering, causes safety belt not to be available, is inconvenient.To solve the above-mentioned problems, it needs to design
A kind of automobile safety belt retractor equipped with anti-locking device can avoid the latch functions quilt of safety belt under normal operating condition
False triggering, in unexpected situations, latch functions can be normally-open, guarantee occupant safety.
Chinese patent application publication number CN101497333B, publication date is on 07 04th, 2012, entitled " to be used for seat
The locking unit of belt retractor " discloses a kind of locking unit, the tape spool being wrapped about for seat harness to be arranged in
An end seat belt retractor.When seat harness rapid deployment, the locking unit of the utility model is by seat
Seat belt locking, when seat harness is contracted, locking unit prevents seat harness to be locked up.Locking unit includes lock
Only arm, be non-rotatably disposed to the central gear with axis center, starter toothed wheel and lock pin, when safety belt is contracted,
Lock pin stops the locking protruding portion of lockup arm.But the device can not still solve the above problems.
Summary of the invention
The utility model in order to overcome the shortcomings in the prior art, provides a kind of car belt volume equipped with anti-locking device
Device is received, can avoid the latch functions of safety belt by false triggering under normal operating condition, while locking function in unexpected situations
Can be normally-open, guarantee occupant safety.
To achieve the goals above, the utility model uses following technical scheme:
A kind of automobile safety belt retractor equipped with anti-locking device, including coiler ontology and with feeling anti-locking device；Retracting
Device ontology includes fixed shell, mandrel, latch assembly and inertial mass；Mandrel and fixed shell rotation connection, latch assembly and core
